LCX017DLT 4.6cm (1.8 Type) Black-and-White LCD Panel Description The LCX017DLT is a 4.6cm diagonal active matrix TFT-LCD panel addressed by polycrystalline silicon super thin film transistors with a built-in peripheral driving circuit. Use of three LCX017DLT 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 (Dual Metal Shield) structure realizes a high luminance screen. And new cross talk free and ghost free structures 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 S-XGA 5:4 and PC-98 8:5 data signals by changing the active area according to the type of input signal.

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 768 gate lines sequentially in a single horizontal scanning period. (XGA mode) • A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits, applies selected pulses to every 1024 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 768 × 1024 dots to display a picture in a single vertical scanning period. • The data and video signals shall be input with the 1H-inverted system.

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) 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 0.294N · m or less. i) Use appropriate filter to protect a panel. j) Do not pressure the portion other than mounting hole (cover). – 25 – LCX017DLT Package Outline Unit: mm 5.4 ± 0.1 4 16.5 ± 0.05 Thickness of the connector 0.3 ± 0.05 2.35 ± 0.1 Incident light Polarizing Axis 2 3 5 6 107.6 ± 1.4 50.0 ± 0.1 3-φ2.3 ± 0.05 C0.8 56.0 ± 0.15 3.0 4-R (51.6) 1 7 Incident light Output light Polarizing Axis Active Area 9 3.0 ± 0.1 25.0 ± 0.25 (36.9) (27.6) 2.2 ± 0.1 8 φ2.2 ± 0.1 25.0 ± 0.25 40.0 ± 0.1 No 5.0 ± 0.1 50.0 ± 0.15 P 0.5 ± 0.02 × 31 = 15.5 ± 0.03 0.5 ± 0.1 0.35 ± 0.03 PIN1 4.0 ± 0.4 0.5 ± 0.15 1 PIN32 Description F P C 2 Molding material 3 Outside frame 4 Reinforcing board 5 Reinforcing material electrode (enlarged) The rotation angle of the active area relative to H and V is ± 1°. 6 Glass 1 7 Glass 2 8 Cover 1 9 Cover 2 Mass 25g – 26 – Sony Corporation
