LCD Panel Operations * Through current of the level shifter during power supply cutoff can be reduced by STB pin. (power save mode) Power save mode is set at STB = Low level. * A vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse to every 218 gate lines sequentially in every horizontal scanning period. A vertical shift register scans the gate lines from the top to bottom of the panel at DWN = High level. * The selected pulse is delivered when the enable pin turns to High level. PAL mode images are displayed by controlling the enable and VCK pin. The enable pin should be High when not in use. * A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits applies selected pulses to every 521 signal electrodes sequentially in a single horizontal scanning period. * Vertical and horizontal drivers 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 218 x 521 dots to display a picture in a single vertical scanning period. * Pixel dots are arranged in a delta pattern, where sets of RGB pixels are positioned with 1.5-dot shifted against adjacent horizontal line. 1.5-dot shift of a horizontal driver output pulse against horizontal synchronized signal is required to apply a video signal to each dot properly. 1H reversed displaying mode is required to apply video signal to the panel. * The video signal shall be input with polarity-inverted system in every horizontal cycle. * Timing diagrams of the vertical and the horizontal right-direction scanning (RGT = High level) display cycle are shown below: - 17 - LCX032ANB * This LCD panel provides the following functions. * Right/left inverse mode * Up/down inverse mode These modes are controlled by two signals, RGT and DWN.

The horizontal display cycle consists of 521/3 = 174 clock pulses because of RGB simultaneous sampling. Refer to Description of Operation "3. RGB Simultaneous Sampling." - 18 - LCX032ANB 3. RGB Simultaneous Sampling Horizontal driver samples R, G and B signal simultaneously, which requires the phase matching between R, G and B 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. Two methods are applied for the delaying procedure: Sample and hold and Delay circuit. These two block diagrams are as follows. The LCX032ANB has the right/left inverse function. 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 B and G signals.

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) 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. - 22 - LCX032ANB Package Outline Unit: mm 12.5 0.3 8.5 0.05 Thickness of the connector 0.3 0.05 1.2 0.3 4 (40.7) 1 R 4- 56.1 0.9 2 5 3 6 15.4 0.15 6.1 0.25 (8.97) 8.0 0.25 16.0 0.15 (6.63) 0.5 0.15 3.0 0.3 0.35 +0.04 -0.03 0.5 0.1 4.0 0.5 PIN 1 0 1.
