LCX034ALT

LCX034ALT 1.8cm (0.7 Type) Black-and-White LCD Panel Description The LCX034ALT is a 1.8cm diagonal active matrix TFT-LCD panel addressed by polycrystalline silicon super thin film transistors with a built-in peripheral driving circuit. Use of three LCX034ALT panels provides a full-color representation. The striped arrangement suitable for data projectors is capable of displaying fine text and vertical lines. The adoption of DMS∗1 structure and high light resistance structure realizes a high luminance screen. And cross talk free circuit and ghost free circuit contribute to high picture quality. This panel has a polysilicon TFT high-speed scanner and built-in function to display images up/down and/or right/left inverse. The built-in 5V interface circuit leads to lower voltage of timing and control signals. The panel contains an active area variable circuit which supports SVGA/VGA/PC98∗2 data signals by changing the active area according to the type of input signal. In addition, double-speed processed NTSC/PAL can also be supported. ∗1 Dual Metal Shield ∗2 “PC98” is a treadmark of NEC Corporation.

LCD Panel Operations [Description of basic operations] • A vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse to every 604 gate lines sequentially in a single horizontal scanning period. (in SVGA mode) • A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits, applies selected pulses to every 804 signal electrodes sequentially in a single horizontal scanning period. These pulses are used to supply the sampled video signal to the row signal lines. • 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 604 × 804 dots to display a picture in a single vertical scanning period. • The data and video signals shall be input with the 1H-inverted system. [Description of operating mode] This LCD panel can change the active area by displaying a black frame to support various computer or video signals. The active area is switched by MODE1, 2 and 3. However, the center of the screen is not changed. The active area setting modes are shown below.

To locate the active area in the center of the panel in each mode, polarity of the start pulse and clock phase for both the H and V systems nust be varied.

This requires phase matching between signals SIG1 to SIG6 to prevent the horizontal resolution from deteriorating. Thus, phase matching between each signal is required using an external signal delaying circuit before applying the video signal to the LCD panel. The block diagram of the delaying procedure using the sample-and-hold method is as follows. The following phase relationship diagram indicates the phase setting for right scan (RGT = High level). For left scan (RGT = Low level), the phase settings for signals SIG1 to SIG6 are exactly reversed.

TFT-LCD panels are easily damaged by static charges. 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 mats 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 a clean environment. b) When delivered, the panel surface (glass panel) is covered by a protective sheet. Peel off the protective sheet carefully so as not to damage the glass panel. c) Do not touch the glass panel surface. The surface is easily scratched. When cleaning, use a cleanroom wiper with isopropyl alcohol. Be careful not to leave a stain on the surface. d) Use ionized air to blow dust off the glass panel. (3) Light resistance Orientation film and organic matter such as liquid crystal used inside of the LCD panel deteriorate by the light chemical reaction. As a result, its indication characteristic may irreversible change. The progress of its chemical reaction is influenced by short wavelength side's light (characteristics of UV cut filter) and temperature when quantitiy of light is constant. To control its progress, attach suitable UV cut filter between light source and LCD panel. (Sharp characteristic's filter of λ > 425nm is recommended.) Also, use suitable IR cut filter to lower the temperature of LCD panel and cool the panel carefully. (4) 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 the panel. c) Do not twist or bend the panel or panel frame. d) Keep the panel away from heat sources. e) Do not dampen the panel with water or other solvents. f) Avoid storing or using the panel at a high temperature or high humidity, which may result in panel damages. g) Minimum radius of bending curvature for a flexible substrate must be 1mm. h) Torque required to tighten screws on a panel must be 0.098N · m (measurement screw : JCIS Type 1, M1.7 flat head screw) or less. i) Do not pressure the portion other than mounting hole (cover). – 25 – LCX034ALT Package Outline Unit: mm 4.9 ± 0.2 12.5 ± 0.05 0.3 ± 0.05 Thickness of the connector 2.2 ± 0.1 4 (75.5) 1 5-φ1.8 ± 0.05 2 3 5 Incident light Polarizing Axis 23.0 ± 0.1 26.0 ± 0.15 101.5 ± 1.4 21.0 ± 0.1 25.0 ± 0.15 (14.47) 12.5 ± 0.15 2.0 ± 0.1 12.0 ± 0.15 1.5 ± 0.1 (10.87) P 0.5 ± 0.02 × 23 = 11.5 ± 0.03 0.5 ± 0.1 0.35 ± 0.03 0.5 ± 0.15 4.0 ± 0.4 1.
