- 11 - 8. function description registers ic provides two types of 8-bit registers, namely: in struction register (ir) and data register (dr). the register is selected using the rs pin. when the rs pin is set to "0", the instruction register type is selected. when rs pin is set to "1", the data register type is selected. please refer to the table below. rs r/wb operation 0 0 instruction register write as an internal operation. 0 1 read busy flag (db7) and address counter (db0 to db6) 1 0 data register write as an internal operation (dr to ddram or cgram) 1 1 data register read as an internal operation (ddram or cgram to dr) instruction register (ir) the instruction register is used to store the instruction code (i.e. display clear, cursor home and others), display data ram (ddram) address, and the character generator ram (cgram) address. instruction register can only be written from the mpu. data register (dr) the data register is used as a temporary storage for data that are going to be written into the ddram or cgram as well as those data that are going to be read from the ddram or cgram. busy flag (bf) the busy flag is used to determine whether ic is id le or internally operating. when ic is performing some internal operations, the busy flag is set to "1 ". under this condition, the no other instruction will not be accepted. when rs pin is set to "0" and r/wb pin is set to "1", the busy flag will be outputted to the db7 pin. when ic is idle or has completed its previous internal operation, the busy flag is set to "0". the next instruction can now be processed or executed. address counter (ac) the address counter is used to assign the display data ram (ddram) address and the character generator ram (cgram) address. when address inform ation is written into the instruction register (ir), this address information is sent from the instruction register to the address counter. at the same time, the nature of the address (either cgram or ddram) is determined by the instruction. after writing into or reading from the ddram or cgram, the address counter is automatically increased or decreased by 1 (for write or read function). it must be noted that when the rs pin is set to "0" and r/wb is set to "1", the contents of the address counter are outputted to the pins -- db0 to db6. free datasheet http:///
12 display data ram (ddram) the display data ram (ddram) is used to store the display data which is represented as 8-bit character code. the display data ram supports an extended capacity of 128 x 8-bits or 128 characters. the display data ram address (add) is set in the address counter as a hexadecimal. high order bits low order bits address counter (hex) ac6 ac5 ac4 ac3 ac2 ac1 ac0 an example of a ddram address=39 is given below. ddram address: 39 ac6 ac5 ac4 ac3 ac2 ac1 ac0 0 1 1 1 0 0 1 1-line display (n=0) when the number of characters displayed is less th an 128, the first character is displayed at the head position. the relationship between the ddram address and position on the oled panel is shown below. display position (digit) 1 2 3 4 ????. 126 127 128 ddram address (hexadecimal) 00 01 02 03 ????. 7d 7e 7f for example, when only 8 characters are displayed in one display line, the relationship between the ddram address and position on the oled panel is shown below. display position 1 2 3 4 5 6 7 8 ddram address 00 01 02 03 04 05 06 07 shift left 01 02 03 04 05 06 07 08 shift right 7f 00 01 02 03 04 05 06 free datasheet http:///

20 notes: 1. * = not relevant 2. the character pattern row positions correspond to the cgram data bits -- 0 to 4, where bit 4 is in the left position. 3. character code bits 1 and 2 correspond to the cgra m address bits -- 4 and 5 respectively (2 bits : 4 types) 4. if the cgram data is set to "1", then the selection is displayed. if the cgram is set to "0", there no selection is made. 5. the cgram address bits 0 to 3 are used to defi ne the character pattern line position. the 11th line is the cursor position and its display is formed by the logical or with the cursor. the 11th line cgram data bits 0 to 4 must be set to "0". if any of the 11th line cgram data bits 0 to 4 is set to "1", the corresponding display location will light up regardless of the cursor position. 6. when the character code bits 4 to 7 are set to "0", then the cgram character pattern is selected. it must be noted that character code bit -- 0 and 3 are not relevant and will not have any effect on the character display. because of this, the character pattern shown above ( $ ) can be displayed when the character code is 00h, 01h, 08h or 09h. free datasheet http:///
21 timing generation circuit the timing signals for the internal circuit operations (i.e. ddram, cgram, and cgrom) are generated by the timing generation circuit. the timing signals for the mpu internal operation and the ram read for display are generated separately in order to prevent one from interfering with the other. this means that, for example, when the data is being written into the ddram, there will be no unwanted interference such as flickering in areas other than the display area. oled driver circuit ic provides 16 common drivers and 100 segment driver outputs. when a character font and the number of lines to be displayed have been selected, the corresponding common drivers output the waveform automatically. a non-selection waveform will be outputted by the rest of the common outputs. cursor/blink control circuit the cursor or character blinking is generated by the cu rsor / blink control circuit. the cursor or the blinking will appear with the digit located at t he display data ram (ddram) address set in the address counter (ac). ac6 ac5 ac4 ac3 ac2 ac1 ac0 address counter 0 0 0 0 1 1 1 case 1: for 1-line display example: when the address counter (ac) is set to 0eh, the cursor position is displayed at ddram address 0eh. display position 1 2 3 4 5 ?? 14 15 ?? 19 20 ddram address (hexadecimal) 00 01 02 03 04 ?? 0d 0e ?? 12 13 | cursor position notes: the cursor or blinking appears when the address c ounter (ac) selects the character generator ram (cgram). when the ac selects cgram address, then the cursor or the blinking is displayed in a irrelevant and meaningless position. case 2: for 2-line display example: when the address counter (ac) is set to 46h, the cursor position is displayed at ddram address 46h. display position 1 2 3 4 5 6 7 8 ?? 19 20 00 01 02 03 04 05 06 07 ?? 09 13 ddram address (hexadecimal) 40 41 42 43 44 45 46 47 ?? 49 53 free datasheet http:///

instructions win0010's instruction register (ir) and data register (dr) are the only registers that can be controlled by the mpu. prior to the commencement of it internal operation, win0010 temporarily stores the control information to its instruction register (ir) and data register (dr) in order to easily facilitate interface with various types of mpu. the internal operations of the win0010 are determined by the signals (rs, r/wb, db0 to db7) that are sent from the mpu. these signals are categorized into 4 instructions types, namely: 1, function setting instructions (i.e. display, format, data length etc.) 2. internal ram address setting instructions 3. data transfer with internal ram instructions 4. miscellaneous function instructions the generally used instructions are those that execute data transfers with the internal ram. however, when the internal ram addresses are auto incremented/decremented by 1 after each data write, the program load of the mpu is lightened. the display shift instruction can be executed at the same time as the display data write, thereby minimizing system development time with maximum programming efficiency. when an instruction is being executed for an inte rnal operation, only the busy flag/address read instruction can be performed. the other instructions are not valid. it should be noted that during the execution of an instruction, the busy flag is set to "1". the busy flag is set to "0" when the instructions are can be accepted and executed. therefore, the busy flag should be checked to make certain that bf = "0" before sending another instruction from the mpu. if not, the time between the first instruction and the next instruction is longer than the time it takes to execute the instruction itself. free datasheet http:///

(ac incremented by 1). 1 0 shifts entire display to the left. the cursor follows the display shift. 1 1 shifts the entire display to the right. the cursor follows the display shift. in a 2-line display, the cursor moves to the second line when it passes the 40th digit of the first line. the first and second line displays will shift at the same time. when the displayed data is shifted repeatedly, each line moves only horizontally. the second line display does not shift into the first line position. the address counter (ac) conten ts will not change if the only action performed is a display shift. g/c: graphic mode / character mode selection this bit is used to select the display mode for further process. when g/c = 1, the graphic mode will be selected. when g/c = 0, the character mode will be selected. pwr: enable/disable internal power this bit is used to turn on or turn off the internal power. when pwr = 1, the internal power is turned on. when pwr = 0, the internal power is turned off. function set instruction the function set instruction has three controlling 3 bits, namely: dl, n and f. please refer to the table below. rs r/wb db7 db6 db5 db4 db3 db2 db1 db0 ft0 ft1 f n dl 1 0 0 0 0 free datasheet http:///
dl: interface data length control bit this is used to set the interface data length. when dl is set to "1", the data is sent or received in 8-bit length via the db0 to db7 (for an 8-bit data transfer). when dl is set to "0", the data is sent or received in 4-bit length via db4 to db7 (for a 4-bit data transfer). when the 4-bit data length is selected, the data must be sent or received twice. n: number of display line this is used to set the number of display lines. when n="1", the 2-line display is selected. when n is set to "0", the 1-line display is selected. f: character font set this is used to set the character font set. when f is set to "0", the 5 x 8 dot character font is selected. when f is set to "1", the 5 x 10 dot character font is selected. it must be noted that the character font setting must be performed at the head of the program before executing any instructions other than the busy flag and address instruction. otherwise, the function set instruction cannot be executed unless the interface data length is changed. ft1, ft0: font table selection these two bits are used to select one font table out of the three for further process. when (ft1, ft0) = (0, 0), the english_japanese character font table will be selected. (ft1, ft0) = (0, 1), the western european character font table will be selected. (ft1, ft0) = (1, 0), the english_russian character font table will be selected. (ft1, ft0) = (1, 1), n/a note: the default setting for ft1 and ft0 is 0 and 0 respectively which means the default font table is english_japanese character font table. set cgram address instruction this instruction is used to set the cgram addre ss binary aaaaaa into the address counter. data is then written to or read from the mpu for cgram. rs r/wb db7 db6 db5 db4 db3 db2 db1 db0 0 0 0 0 a cg a cg a cg a cg a cg a cg note: acg is the cgram addres set ddram address instruction this instruction is used to set the ddram address binary aaaaaaa into the address counter. the data is written to or read from the mpu for the ddram. if 1-line display is selected (n="0"), then aaaaaaa can be 00h to 4fh. when the 2-line disp lay is selected, then aaaaaaa can be 00h to 27h for the first line and 40h to 67h for the second line. rs r/wb db7 db6 db5 db4 db3 db2 db1 db0 0 0 1 a dd a dd a dd a dd a dd a dd a dd free datasheet http:///

(2)don?t make extra holes on the printed circuit board, modify its shape or change the components of oled module. (3)don?t disassemble the oledm. (4)don?t operate it above the absolute maximum rating. (5)don?t drop, bend or twist oledm. (6)soldering: only to the i/o terminals. (7)storage: please storage in anti-static electricity container and clean environment. 17.1 handling precautions (1) since the display panel is being made of gl ass, do not apply mechanical impacts such us dropping from a high position. (2) if the display panel is broken by some accident and the internal organic substance leaks out, be careful not to inhale nor lick the organic substance. (3) if pressure is applied to the display surface or its neighborhood of the oled display module, the cell structure may be damaged and be careful not to apply pressure to these sections. (4) the polarizer covering the surface of the oled display module is soft and easily scratched. please be careful when handling the oled display module. (5) when the surface of the polarizer of the ol ed display module has soil, clean the surface. it takes advantage of by using following adhesion tape. * scotch mending tape no. 810 or an equivalent never try to breathe upon the soiled surface nor wipe the surface using cloth containing solvent such as ethyl alcohol, since the surf ace of the polarizer will become cloudy. also, pay attention that the following liquid and solvent may spoil the polarizer: * water * ketone * aromatic solvents (6) hold oled display module very carefully when placing oled display module into the system housing. do not apply excessive stress or pressure to oled display module. and, do not over bend the film with electrode pattern layouts. these stresses will influence the display performance. also, secure sufficient rigidity for the outer cases. free datasheet http:///
(7) do not apply stress to the lsi chips and the surrounding molded sections. (8) do not disassemble nor modify the oled display module. (9) do not apply input signals while the logic power is off. (10) pay sufficient attention to the working environments when handing oled display modules to prevent occurrence of element breakage accidents by static electricity. * be sure to make human body grounding when handling oled display modules. * be sure to ground tools to use or assembly such as soldering irons. * to suppress generation of static electricity, avoid carrying out assembly work under dry environments. * protective film is being applied to the surface of the display panel of the oled display module. be careful since static electricity may be generated when exfoliating the protective film. (11) protection film is being applied to the surface of the display panel and removes the protection film before assembling it. at this time, if the oled display module has been stored for a long period of time, residue adhesive material of the protection film may remain on the surface of the display panel after removed of the film. in such case, remove the residue material by the method introduced in the above section 5. (12) if electric current is applied when the oled display module is being dewed or when it is placed under high humidity environments, the el ectrodes may be corroded and be careful to avoid the above. 8.2 storage precautions (1) when storing oled display modules, put them in static electricity preventive bags avoiding exposure to direct sun light nor to light s of fluorescent lamps. and, also, avoiding high temperature and high humidity environment or low temperature (less than 0c) environments. (we recommend you to store these modules in the packaged state when they were shipped from winstar technology inc. at that time, be careful not to let water drops adhere to the packages or bags nor let dewing occur with them. (2) if electric current is applied when water drops are adhering to the surface of the oled display module, when the oled display module is being dewed or when it is placed under high humidity environments, the electrodes may be corroded and be careful about the above. 8.3 designing precautions (1) the absolute maximum ratings are the ratings which cannot be exceeded for oled display module, and if these values are exceeded, panel damage may be happen. (2) to prevent occurrence of malfunctioning by noise, pay attention to satisfy the vil and vih specifications and, at the same time, to make the signal line cable as short as possible. (3) we recommend you to install excess current preventive unit (fuses, etc.) to the power circuit (vdd). (recommend value: 0.5a) (4) pay sufficient attention to avoid occurrence of mutual noise interference with the neighboring devices. (5) as for emi, take necessary measures on the equipment side basically. (6) when fastening the oled display module, fasten the external plastic housing section. (7) if power supply to the oled display module is forcibly shut down by such errors as taking out the main battery while the oled display panel is in operation, we cannot guarantee the quality of this oled display module. free datasheet http:///
* connection (contact) to any other potential than the above may lead to rupture of the ic. precautions in use of oled modules-2 (1)avoid applying excessive shocks to module or making any alterations or modifications to it. (2)don?t make extra holes on the printed circuit board, modify its shape or change the components of oled module. (3)don?t disassemble the oledm. (4)don?t operate it above the absolute maximum rating. (5)don?t drop, bend or twist oledm. (6)soldering: only to the i/o terminals.

8.4 precautions when disposing of the oled display modules 1) request the qualified companies to handle i ndustrial wastes when disposing of the oled display modules. or, when burning them, be sure to observe the environmental and hygienic laws and regulations. 8.5 other precautions (1) when an oled display module is operated for a long of time with fixed pattern may remain as an after image or slight contrast deviation may occur. nonetheless, if the operation is interrupted and left unused for a while, normal state can be restored. also, there will be no problem in the reliability of the module. (2) to protect oled display modules from performan ce drops by static electricity rapture, etc., do not touch the following sections whenever possible while handling the oled display modules. * pins and electrodes * pattern layouts such as the tcp & fpc (3) with this oled display module, the oled driver is being exposed. generally speaking, semiconductor elements change their characteristics when light is radiated according to the principle of the solar battery. consequently, if this oled driver is exposed to light, malfunctioning may occur. * design the product and installation method so that the oled driver may be shielded from light in actual usage. * design the product and installation method so that the oled driver may be shielded from light during the inspection processes. (4) although this oled display module stores the operation state data by the commands and the indication data, when excessive external noise, etc. enters into the module, the internal status may be changed. it therefore is necessary to take appropriate measures to suppress noise generation or to protect from influences of noise on the system design. (5) we recommend you to construct its software to make periodical refreshment of the operation statuses (re-setting of the commands and re-transference of the display data) to cope with catastrophic noise. (6)resistors,capacitors and other passive components will have different appearance and color caused by the different supplier. (7)our company will has the right to upgrade and modify the product function. free datasheet http:///
