LCX020BK 1.8cm (0.7-inch) Color LCD Panel Description The LCX020BK is a 1.8cm diagonal active matrix TFT-LCD panel addressed by polycrystalline silicon super thin film transistors with built-in peripheral driving circuit. This panel provides full-color representation. RGB dots are arranged in a striped pattern optimum for data applications and capable of displaying fine text and vertical lines. The adoption of an advanced on-chip black matrix realizes a high luminance screen, and high picture quality is possible with built-in cross talk free and ghost free circuits. This panel has a polysilicon TFT high-speed scanner and built-in function to display images up/down and/or right/left inverse. In addition, the built-in 5V interface circuit leads to lower voltage of timing and control signals. The panel contains a display area varying circuit which supports Macintosh16∗1/SVGA/VGA/PC98∗2 data signals by changing the display area according to the type of input signal. In addition, double-speed processed NTSC/PAL/WIDE can also be supported. ∗1 "Macintosh" is a trademark of Apple Company Inc. ∗2 "PC98" is a trademark of NEC.

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 624 gate lines sequentially in every single horizontal scanning period. (in Macintosh16 mode) • A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits, applies selected pulses to every 2496 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 for one dot) turn on to apply a video signal to the dot. The same procedures lead to the entire 2496 × 832 dots to display a picture in a single vertical scanning period. • The data and video signals shall be input with polarity-inverted system in every horizontal cycle. [Description of operating mode] The LCD panel can change the angle of view by displaying a black frame to support various signal systems. The angle of view is switched by MODE1, 2 and 3. However, the picture center does not change. The angle of view mode settings are shown below. MODE1 MODE2 MODE3 Display mode L L L Macintosh16: 832 × 624 L L H SVGA: 800 × 600 L H L PAL: 762 × 572 L H H VGA/NTSC: 640 × 480 H L L PC98: 640 × 400 H L H WIDE: 832 × 480 The LCD panel has the following functions to easily apply to various uses, as well as various signal systems. • Right/left inverse mode • Up/down inverse mode These modes are controlled by two signals (RGT and DWN). The right/left and up/down mode settings are shown in the tables below. RGT Mode DWN Mode H Right scan H Down scan L Left scan L Up scan Right/left and up/down mean the direction when the Pin 1 marking is located at the right side with the pin block facing upward. Since the display area is located in the center of the panel in each mode, the start pulse, clock phase and polarity for both the H and V systems must be varied. The phase relationship between the start pulse and the clock for each mode is shown on the following pages. – 17 – LCX020BK (1) Vertical direction display cycle (1.1) Macintosh 16 VD VST (DWN = H) VST (DWN = L) VCK 1 2 3 621 622 623 624 4 Vertical display cycle 624H (1.2) SVGA VD VST (DWN = H) VST (DWN = L) VCK 1 2 3 597 598 599 600 4 Vertical display cycle 600H (1.3) PAL VD VST (DWN = H) VST (DWN = L) 1 VCK 2 3 4 569 570 571 572 Vertical display cycle 572H (1.4) VGA/NTSC, WIDE VD VST (DWN = H) VST (DWN = L) VCK 1 2 3 4 477 478 479 480 Vertical display cycle 480H (1.5) PC98 VD VST (DWN = H) VST (DWN = L) VCK 1 2 3 4 397 398 399 400 Vertical display cycle 400H – 18 – LCX020BK (2) Horizontal direction display cycle (2.1.1) Macintosh 16, WIDE, RGT = H HD HST 1 HCK1 2 3 4 137 138 139 140 HCK2 Horizontal display cycle (2.1.2) Macintosh 16, WIDE, RGT = L HD HST 1 HCK1 2 3 4 137 138 139 140 HCK2 Horizontal display cycle (2.2.1) SVGA, RGT = H HD HST HCK1 1 2 3 HCK2 4 131 132 133 134 Horizontal display cycle (2.2.2) SVGA, RGT = L HD HST HCK1 HCK2 1 2 3 4 131 132 133 134 Horizontal display cycle – 19 – LCX020BK (2.3.1) PAL, RGT = H HD HST HCK1 1 2 3 HCK2 4 125 126 127 128 Horizontal display cycle (2.3.2) PAL, RGT = L HD HST HCK1 1 2 3 HCK2 4 125 126 127 128 Horizontal display cycle (2.4.1) VGA/NTSC/PC98, RGT = H HD HST HCK1 1 2 3 HCK2 4 105 106 107 108 Horizontal display cycle (2.4.2) VGA/NTSC/PC98, RGT = L HD HST HCK1 HCK2 1 2 3 4 105 106 107 108 Horizontal display cycle – 20 – LCX020BK 3. 18-dot Simultaneous Sampling The horizontal shift register performs SIGR1 to SIGR6, SIGG1 to SIGG6 and SIGB1 to SIGB6 signal sampling simultaneously, which requires phase matching between each signal to prevent the horizontal resolution from deteriorating. Phase matching by an external signal delaying circuit is needed before applying video signals to the LCD panel.

The following phase relationship diagram indicates the phase setting for right-direction scanning (RGT = High level). For leftdirection scanning (RGT = Low level), the phase settings should be inverted for the SIGR1 to SIGR6, SIGG1 to SIGG6 and SIGB1 to SIGB6 signals.

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 dust a) Operate in a clean environment. b) When delivered, panel surface (Polarizer) is covered by a protective sheet. Peel off the protective sheet carefully so as not to damage the panel. c) Do not touch the polarizer surface. The surface is easily scratched. When cleaning, use a clean-room wiper with isopropyl alcohol. Be careful not to leave a stain on the surface. d) Use ionized air to blow dust off the polarizer. (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. – 23 – LCX020BK Package Outline Unit: mm 18.0 ± 0.3 Thickness of the connector 12.0 ± 0.05 0.2 ± 0.03 2 0.3 ± 0.3 2.761 ± 0.1 17.6 ± 0.3 1.075 ± 0.3 19.65 ± 0.15 0.05 ± 0.3 47.75 ± 0.9 3 Incident light 4 4 Reinforcing material 1.5 ± 1.0 19.75 ± 0.15 18.25 ± 0.15 5.0 ± 0.3 (14.227) 0.05 ± 0.3 (10.608) 9±3 6±3 Active Area 14.0 ± 0.3 Polarizing Axis 0.3 ± 0.3 1.754 ± 0.1 1 (26.0) electrode 0.8 ± 0.1 1.9 ± 0.3 2.33 ± 0.4 19.75 ± 0.15 P 0.6 ± 0.02 × 19 = 11.4 ± 0.03 P 0.6 ± 0.02 × 18 = 10.8 ± 0.03 0.3 ± 0.07 0.6 ± 0.07 No Description 1 F P C 2 Reinforcing board 3 Reinforcing material 4 Polarizing film PIN 39 PIN1 weight 2g electrode (enlarged) – 24 –
