LCX027AK
Level Conversion Circuit The LCX027AK has a built-in level conversion circuit in the clock input unit located inside the panel. The circuit voltage is stepped up to VDD inside the panel. This level conversion circuit meets the specifications of a 3.0V power supply of the externally-driven IC. 1. I/O characteristics of level conversion circuit
Output voltage (inside panel)
(For a single-phase input unit) An example of the I/O voltage characteristics of a level conversion circuit is shown in the figure to the right. The input voltage value that becomes half the output voltage (after voltage conversion) is defined as Vth. The Vth value varies depending on the VDD voltage. The Vth values under standard conditions are indicated in the table below. (HST, VST, EN, CLR, RGT, VCK and BLK in the case of a single-phase input)

(For a differential input unit) An example of I/O voltage characteristics of a level conversion circuit for a differential input is shown in the figure to the right. Although the characteristics, including those of the Vth voltage, are basically the same as those for a single-phased input, the twophased input phase is defined. (Refer to clock timing conditions.)

2. Current characteristics at the input pin of level conversion circuit A slight pull-in current is generated at the input pin of the level conversion circuit. (The equivalent circuit is shown to the right.) The current volume increases as the voltage at the input pin decreases, and is maximized when the pin is grounded.

9. Method of Measuring the Optimum Vcom There are two methods of measuring the optimum Vcom using the photoelectric element. 9-1. Method of Measuring Flicker In the field invert drive mode, adjust the flicker level of the half tone (Vsig = 1.5 to 2.5V) using the photoelectric element and oscilloscope so that its 30Hz component becomes minimum. The Vcom value at this time is taken to be the optimum Vcom. 9-2. Method of Measuring Contrast In the normal 1H invert drive mode, adjust the optical output voltage of the half tone (Vsig = 1.5 to 2.5V) so that it becomes minimum. The Vcom value at this time is taken to be the optimum Vcom.

2. LCD Panel Operations * A vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse to every 225 gate lines sequentially in every horizontal scanning period. A vertical shift register scans the gate lines from the top to bottom of the panel. * 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 800 signal electrodes sequentially in a single horizontal scanning period. * Scanning direction of horizontal shift register can be switched with RGT pin. Scanning direction is left to right for RGT pin at High level; and right to left for RGT pin at Low level. (These scanning directions are from a front view.) Normally, set to High level. * 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 225 x 800 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. HCK1 and HCK2 should be inverted to display the left-direction horizontal scanning (RGT = Low level). This inversion enables the center of the image to be fixed by eliminating offsets. (When an example of system mentioned on this data sheet is used, TG performs this operation automatically.)

LCX027AK
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 LCX027AK 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.

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) 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.
