?17 LCX012BL 2. lcd panel operations [description of basic operations] the basic operations of the lcd panel are shown below based on the vga mode. a vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse to every 484 gate lines sequentially in every horizontal scanning period. two lines of horizontal electrodes are sequentially selected in ntsc/pal mode. a horizontal driver, which consists of horizontal shift registers, gates and cmos sample-and-hold circuits, applies selected pulses to every 644 signal electrodes sequentially in a single horizontal scanning period. vertical and horizontal shift registers address one pixel, and then thin film transistors (tfts; two tfts) turn on to apply a video signal to the dot. the same procedures lead to the entire 484 644 dots to display a picture in a single vertical scanning period. to change the combination of the horizontal electrode in ntsc/pal mode, the phase of vck need to be inverted. normally, switching every field maximizes vertical resolution. 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 1h-inverted system. timing diagrams of the vertical for vga mode and ntsc/pal mode and the horizontal display cycle are shown below: vertical display cycle 480h 1 2 480 (1) vertical display cycle (vga) vd vst (dwn = high level) vck (2) horizontal display cycle horizontal display cycle 1 2345 6 108 109 hd hst hck1 hck2 vst (dwn = low level)
?18 LCX012BL the direction of the right/left and/or up/down mean when pin 1 marking is located at right side with the pin block upside. to improve uniformity, the analog signals psig shall be input by synchronizing with sig1 to sig6. when the up-scan mode (dwn = low level) is set, the phase of vst shall be inverted 3. 6-dot simultaneous sampling and dot-inverted drive horizontal driver samples sig1 to sig6 signal simultaneously. which requires the phase matching between sig1 to sig6 signals to prevent horizontal resolution from deteriorating. thus phase matching between each signal is required using an external signal delaying circuit before applying video signal to the lcd panel. the block diagram of the delaying procedure using sample-and-hold method is as follows. the following phase relationship diagram indicates the phase setting for the right scan (rgt = high level). for the left scan (rgt = low level), the phase setting shall be inverted between sig1 to sig6 signals. s / h ck1 ck2 sig3 sig6 sig1 LCX012BL ac amp sig3 sig6 sig1 sig2 sig2 sig4 sig4 sig5 sig5 ck3 ck4 ck5 s / h s / h s / h s / h s / h ck6 s / h s / h s / h s / h s / h ac amp ac amp ac amp ac amp ac amp 8 7 6 5 4 3 [description of operating mode] the lcd panel has the following functions to easily apply to various uses, as well as various broadcasting systems. right/left inverse mode up/down inverse mode these modes are controlled by two signals (rgt and dwn). the setting mode is shown below. dwn h l down scan up scan mode rgt h l right scan left scan mode hckn ck1 ck3 ck5 ck2 ck4 ck6 (right scan)

?20 LCX012BL 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 ionozed air to discharge the panels. (2) protection from dust and dirt a) operate 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.
