LCX007CN 3.4cm (1.35-inch) Black-and-White LCD Panel Description The LCX007CN is a 3.4cm diagonal active matrix TFT-LCD panel addressed by polycrystalline silicon super thin film transistors with built-in peripheral driving circuit. Use of three panels in combination with the LCX007CL provides a full-color representation. (The LCX007CN has the visual field angle characteristics of mirror symmetry to those of the LCX007CL.) This panel provides a wide aspect ratio of 16:9, such as those represented in HD. The built-in sideblack function also allows an aspect ratio of 4:3 in the NTSC/PAL mode. 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 system and control signals.

LCD Panel Operations [Description of basic operations] The basic operations of the LCD panel are shown below based on the wide-display mode. • A vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse to every 480 gate lines sequentially in every horizontal scanning period. • A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits, applies selected pulses to every 1068.5 signal electrodes sequentially in a single horizontal scanning period. • Vertical and horizontal shift registers 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 480 x 1068.5 dots to display a picture in a single vertical scanning period. • The LCD pixel dots are arranged in a delta pattern, where the dots connected to the identical signal line are positioned with 1.5-dot offset against those of the adjacent horizontal line. Horizontal Start Pulse (HST) is generated with 1.5-bit offset between the horizontal lines to regulate the above offset. HCK and sample-hold (S/H) pulses follow the same 1.5-bit offset scheme. • The CLR pin is provided to eliminate the shading effect caused by the coupling of selected pulses. While maintaining the CLR at High level, the VVDD potential drops to approximately 9.5V. This pin shall be grounded when not in use. • The video signal shall be input with polarity-inverted system in every horizontal cycle. • Timing diagrams of the vertical and the horizontal display cycle are shown below: (1) Vertical display cycle VD VST VCK 1 2 480 Vertical display cycle 480H (2) Horizontal display cycle (16:9) BLK HST 356 HCK1 1 2 3 4 5 6 357 HCK2 Horizontal display cycle (3) Horizontal display cycle (4:3) BLK HST 267 HCK1 1 2 3 4 5 6 268 HCK2 Horizontal display cycle – 18 – LCX007CN [Description of operating mode] The LCD panel has the following functions to easily apply to various uses, as well as various broadcasting systems. • Right/left inverse mode • Up/down inverse mode • 4:3 display mode with side-black display These modes are controlled by three signals (RGT, DWN, and WID). The setting mode is shown below: WID RGT Mode DWN Mode H H 16:9 right scan H Down scan H L 16:9 left scan L Up scan L H 4:3 right scan L L 4:3 left scan The direction of the right/left and/or up/down mean when Pin 1 marking is located at right side with the pin block upside. • The analog signal (SID) to display side-black shall be input by 1H inversion synchronized with the signal. 3. 3-dot Simultaneous Sampling SIG2 S/H S/H CK2 CK3 SIG1 SIG3 S/H S/H CK1 CK3 S/H AC Amp 3 SIG2 AC Amp 2 SIG1 AC Amp 4 SIG3 CK3 <Phase relationship of delaying sample-and-hold pulses> (right scan) HCKn CK2 CK1 CK3 – 19 – LCX007CN Horizontal driver samples SIG1, SIG2 and SIG3 signal simultaneously, which requires the phase matching between SIG1, SIG2, and SIG3 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. The block diagram of the delaying procedure using sample-and-hold method is as follows. The LCX007 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 SIG2 and SIG3 signals. LCX007CN Display System Block Diagram An example of display system is shown below.

LCX007CN Important (1) Anti-reflection coating Use anti-reflection coating when using a phase-shifting plate on a light egress side of the LCD to align a polarization axis with those of a polarization screen or a prism. (2) Direction of incident light Allow incident light to hit upon an opposite side of a mark-indicated surface. Direction of incidence Marking side (3) Polarizer This LCD is attached with a polarizer on a light egress side. A suitable heat-dissipation method shall be incorporated to suppress optical degradation of a polarizer. (4) Light source • Use visible light (wavelength λ = 400 to 780nm) as a light source. Do not use a light source containing infrared or ultraviolet components. • Suppress leakage light (reflection light) into a backside of a panel to sufficiently weak level or shut it out completely. – 22 – LCX007CN 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) Handle 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. g) Minimum radius of bending curvature for a flexible substrate must be 1mm. h) Torque required to tighten screws on a panel must be 3kg · cm or less. – 23 – LCX007CN Package Outline Unit: mm 3.4 ± 0.1 31.4 ± 0.2 4.55 ± 0.1 Thickness of the connector 0.3 ± 0.05 21.0 ± 0.15 9.75 ± 1.5 1.8 ± 0.1 1 (40.5) (42.5) 4 3 Active Area 5 2 6 Incident light Polarizing Axis 30.75 ± 0.2 34.0 ± 0.2 36.0 ± 0.15 76.5 ± 1.3 0.5 2-R 2-φ3.5 20.25 ± 0.25 40.5 ± 0.15 2.0 ± 0.1 0 φ2.5 – 0.1 (16.8) (29.9) 13.6 ± 0.25 7 No 1.5 ± 0.15 P 1.0 × 19 = 19.0 ± 0.1 PIN20 PIN1 0.5 ± 0.15 1.0 ± 0.15 4.0 ± 0.3 1 0.6 ± 0.05 Description F P C 2 Molding material 3 Outside frame 4 Reinforcing board 5 Reinforcing material 6 electrode (enlarged) 7 The rotation angle of the active area relative to H and V is ± 1°. – 24 – Polarizing film Cover weight 7g
