NL12876BC26-28 data sheet dod-pp-0853 (3rd edition) 4 1. outline 1.1 structure and principle color lcd module NL12876BC26-28 is composed of the amorphous silicon thin film transistor liquid crystal display (a-si tft lcd) panel structure with driver lsis for dr iving the tft (thin film transistor) array and a backlight. the a-si tft lcd panel structure is injected liqu id crystal material into a narrow gap between the tft array glass substrate and a color-filter glass substrate. color (red, green, blue) data signals from a host system (e.g. signal generator, etc.) are modulated into best form for active matrix system by a signal processing circuit, and sent to the driver lsis which drive the individual tft arrays. the tft array as an electro-optical switch regulates the amount of transmitted light from the backlight assembly, when it is controlled by data signals. color images are created by regulating the amount of transmitted light through the tft array of red, green and blue dots. 1.2 application ? for industrial use 1.3 features ? ultra-wide viewing angle (adoption of ultra - advanced super fine tft (ua-sft)) ? high luminance ? high contrast ? wide color gamut ? wide temperature range ? lvds interface ? edge light type (without inverter) ? acquisition product for ul60950-1/csa c22.2 no.60950-1-03 (file number: e170632) ? compliance with the european rohs directive (2002/95/ec) www.datasheet.co.kr datasheet pdf - http://www..net/

"vs" and "vblh" are the voltage value between low voltage si de (cold) and high voltage side (hot). note3: the asymmetric ratio of working waveform for lamps (power supply voltage peak ratio, power supply current peak ratio and waveform space ratio) should be less than 5 % (see the following figure.). if the wavefo rm is asymmetric, dc (direct current) element apply into the lamp. in this case, a lamp lifetime may be shortened, because a distribution of a lamp enclosure substance inclines toward one side between low voltage terminal (cold terminal) and high voltage terminal (hot terminal). when designing the inverter, evaluate asymmetric of lamp working waveform sufficiently. pa: supply voltage/current peak for positive, pb: supply voltage/current peak for negative sa: waveform space for positive part, sb: waveform space for negative part. note4: the inverter should be designed so that the lamp starting voltage can be maintained for more than 1 second. otherwise the lamp may not be turned on. note5: in case "fo" is not the recommended value, beat noise may display on the screen, because of interference between "fo" and "1/th". recommended value of "fo" is as following. th: horizontal cycle (see " 4.8.2 timing characteristics ".) n : natural number (1, 2, 3 ???????? ) note6: method of lamp cable installation may invite fluctuation of lamp current and voltage or asymmetric of lamp working waveform. when designing method of lamp cable installation, evaluate the fluctuation of lamp current, voltage and working waveform sufficiently. fo = 1 4 1 th (2n-1) pa pb sa sb 0 | pa - pb | pb 100 5% 100 5% | sa - sb | sb www.datasheet.co.kr datasheet pdf - http://www..net/

(shock: to be not greater 294m/s 2 and to be not greater 11ms, pressure: to be not greater 19.6 n ( 16mm jig)) 7.3 attentions 7.3.1 handling of the product take hold of both ends without touching the circuit board when the product (lcd module) is picked up from inner packing box to avoid broken down or misadjustment, because of stress to mounting parts on the circuit board. do not hook nor pull cables such as lamp cable, and so on, in order to avoid any damage. when the product is put on the table temporar ily, display surface must be placed downward. when handling the product, take the measures of electrostatic discharge with such as earth band, ionic shower and so on, because the product may be damaged by electrostatic. the torque for product mounting screws must never exceed 0.343n ? m. higher torque might result in distortion of the bezel. and the length of product mounting screws must be 2.8mm. ! www.datasheet.co.kr datasheet pdf - http://www..net/
NL12876BC26-28 data sheet dod-pp-0853 (3rd edition) 27 the product must be installed using mounting holes without undue stress such as bends or twist (see outline drawings). and do not add undue stress to any portion (such as bezel flat area). bends or twist described above and undue stress to any portion may cause display mura. recommended installing method: ideal plane "a" is defined by one mounting hole (datum point) and other mounting holes. the ideal plane "a" should be the same plane within 0.3 mm. do not press or rub on the sensitive product su rface. when cleaning the product surface, wipe it with a soft dry cloth. do not push nor pull the interface connec tors while the product is working. do not bend or unbend the lamp cable at the near part of the lamp holding rubber, to avoid the damage for high voltage side of the lamp. properly connect the plug (backlight side) to adap table socket (inverter side) without incomplete connection. after connecting, be careful not to hook the lamp cables because incomplete connection may occur by hooking the lamp cable s. this incomplete connection may cause abnormal operation of high voltage circuit. ? if the lamp cable is attached on the metal part of the product directly, high frequency leak current to the metal part may occur, then the brightness may decrease or the lamp may not be turned on. ? when not connecting fg of the lcd module to th e customer's equipment ground, inverter noise may create video noise on the lcd screen. ? when handling the product, use of an original protection sheet on th e product surface (polarizer) is recommended for protection of product surface. adhe sive type protection sheet may change color or characteristics of the polarizer. ? usually liquid crystals don't l eak through the breakage of glasse s because of the surface tension of thin layer and the construction of lcd panel. but, if you contact with liquid crystal for the worst, please wash it out with soap. 7.3.2 environment do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases. keep the product in packing box with antistatic pouch in room temperature to avoid dusts and sunlight, when storing the product. in order to prevent dew condensation occurring by temperature difference, the product packing box should be opened after enough time being left under the environment of an unpacking room. evaluate the leaving time suffici ently because a situation of dew condensation occurring is changed by the environmental temperature and humidity. (recommended leaving time: 6 hours or more with packing state) do not operate in high magnetic field. circuit boards may be broken down by it. this product is not designed as radiation hardened. product mounting hole "d" mounting hole "f" ideal plane "a" mounting hole "a" (datum point) mounting hole "c" www.datasheet.co.kr datasheet pdf - http://www..net/
