?18 LCX007BNB 2. lcd panel operations [description of basic operations] the basic operations of the lcd panel are shown below based on the wide-display mode. a vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse to every 480 gate lines sequentially in every horizontal scanning period. a horizontal driver, which consists of horizontal shift registers, gates and cmos sample-and-hold circuits, applies selected pulses to every 1068.5 signal electrodes sequentially in a single horizontal scanning period. vertical and horizontal shift registers address one pixel, and then turn on thin film transistors (tfts; two tfts) to apply a video signal to the dot. the same procedures lead to the entire 480 1068.5 dots to display a picture in a single vertical scanning period. the lcd pixel dots are arranged in a delta pattern, where the dots connected to the identical signal line are positioned with 1.5-dot offset against those of the adjacent horizontal line. horizontal start pulse (hst) is generated with 1.5-bit offset between the horizontal lines to regulate the above offset. hck and sample-hold (s/h) pulses follow the same 1.5-bit offset scheme. the clr pin is provided to eliminate the shading effect caused by the coupling of selected pulses. while maintaining the clr at high level, the vv dd potential drops to approximately 9.5v. this pin shall be grounded when not in use. the video signal shall be input with polarity-inverted system in every horizontal cycle. timing diagrams of the vertical and the horizontal display cycle are shown below: vertical display cycle 480h 1 2 480 (1) vertical display cycle vd vst vck horizontal display cycle 123 45 6 356 357 (2) horizontal display cycle (16:9) blk hst hck1 hck2 (3) horizontal display cycle (4:3) horizontal display cycle 1 2345 6 267 268 blk hst hck1 hck2

?22 LCX007BNB marking side direction of incidence important (1) direction of incident light allow incident light to hit upon an opposite side of a mark-indicated surface. (2) polarizer this lcd is attached with a polarizer. a suitable heat-dissipation method shall be incorporated to suppress optical degradation of a polarizer. (3) light source use visible light (wavelength l = 400 to 780nm) as a light source. do not use a light source containing infrared or ultraviolet components. suppress leakage light (reflection light) into a backside of a panel to sufficiently weak level or shut it out completely.
?23 LCX007BNB notes on handling (1) static charge prevention be sure to take following protective measures. tft-lcd panels are easily damaged by static charge. a) use non-chargeable gloves, or simply use bare hands. b) use an earth-band when handling. c) do not touch any electrodes of a panel. d) wear non-chargeable clothes and conductive shoes. e) install conductive mat on the working floor and working table. f) keep panels away from any charged materials. g) use ionized air to discharge the panels. (2) protection from dust and dirt a) handle in clean environment. b) when delivered, a surface of a panel (polarizer) is covered by a protective sheet. peel off the protective sheet carefully not to damage the panel. c) do not touch the surface of a panel. the surface is easily scratched. when cleaning, use a clean-room wiper with isopropyl alcohol. be careful not to leave stain on the surface. d) use ionized air to blow off dust at a panel. (3) other handling precautions a) do not twist or bend the flexible pc board especially at the connecting region because the board is easily deformed. b) do not drop a panel. c) do not twist or bend a panel or a panel frame. d) keep a panel away from heat source. e) do not dampen a panel with water or other solvents. f) avoid to store or to use a panel in a high temperature or in a high humidity, which may result in panel damages. g) minimum bent radius rating for flexible substrates is 1mm. h) panel screw torque should not exceed 3kg ?cm.
