| LCX016AM 3.3cm (1.3-inch) Black-and-White LCD Panel Preliminary For the availability of this product, please contact the sales office. Description The LCX016AM is a 3.3cm diagonal active matrix TFT-LCD panel addressed by polycrystalline silicon super thin film transistors with a built-in peripheral driving circuit. Use of three LCX016AM 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 an advanced on-chip black matrix realizes high picture quality without cross talk by incorporating a high luminance screen and cross talk free circuit. 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 MAC17/SVGA/VGA/PC98 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. The adoption of a micro-lens increases the utilization efficiency of incident light, resulting in an optical transmittance of 30% or more with parallel incident light. Features * Number of active dots: 519,000 (1.3-inch, 3.3cm in diagonal) * Accepts the computer requirements of MAC17 (832 x 624), SVGA (800 x 600), VGA (640 x 480) and PC98 (640 x 400) platforms * Supports NTSC (640 x 480) and PAL (762 x 572) by processing the video signal at double speed * High optical transmittance: 30% or more (with parallel incident light) * Built-in cross talk free circuit * High contrast ratio with normally white mode: 200 (typ.) * Built-in H and V drivers (built-in input level conversion circuit, 5V driving possible) * Up/down and/or right/left inverse display function Element Structure * Dots: 832 (H) x 624 (V) = 519,168 * Built-in peripheral driver using polycrystalline silicon super thin film transistors Applications * Liquid crystal data projectors * Liquid crystal projectors, etc. Sony reserves the right to change products and specifications without prior notice.

Transmittance [%] 3. V-T Characteristics V-T characteristics, or the relationship between signal amplitude and the transmittance of the panels, are measured by System II by inputting the same signal amplitude VAC to each input pin.

DC and AC (MAC17/SVGA/VGA/PC98/NTSC: 30Hz, rms, PAL: 25Hz, rms) components of the panel output signal for gray raster mode are measured by a DC voltmeter and a spectrum analyzer in System II. F [dB] = 20log { AC component } ...(7) DC component Each input signal voltage for gray raster mode is given by Vsig = 7.0 V50 [V] where: V50 is the signal amplitude which gives 50% of transmittance in V-T characteristics. 6. Image Retention Time Apply the monoscope signal to the LCD panel for 60 minutes and then change this signal to the gray scale of Vsig = 7.0 VAC (VAC: 3 to 4V). Judging by sight at the VAC that holds the maximum image retention, measure the time till the residual image becomes indistinct.

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 a single horizontal scanning period. (in MAC17 mode) * A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits, applies selected pulses to every 832 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 624 x 832 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. The active area setting modes are shown below.

The right/left and/or up/down setting modes are shown below. RGT H L Mode Right scan Left scan DWN H L Mode Down scan Up scan Right/left and/or up/down mean the direction when the Pin 1 marking is located at the right side with the pin block upside. 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 must be varied. The phase relationship between the start pulse and the clock for each mode is shown on the following pages. - 15 - LCX016AM (1) Vertical direction display cycle (1.1) MAC17 VD VST (DWN = H) VST (DWN = L) VCK 1 2 3 4 621 622 623 624 Vertical display cycle 624H (1.2) SVGA VD VST (DWN = H) VST (DWN = L) VCK 1 2 3 4 597 598 599 600 Vertical display cycle 600H (1.3) PAL VD VST (DWN = H) VST (DWN = L) VCK 1 2 3 4 569 570 571 572 Vertical display cycle 572H (1.4) VGA/NTSC 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 - 16 - LCX016AM (2) Horizontal direction display cycle (2.1.1) MAC17, RGT = H HD HST HCK1 HCK2 1 2 3 4 137 138 139 140 Horizontal display cycle (2.1.2) MAC17, RGT = L HD HST HCK1 HCK2 1 2 3 4 137 138 139 140 Horizontal display cycle (2.2.1) SVGA, RGT = H HD HST HCK1 HCK2 1 2 3 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 - 17 - LCX016AM (2.3.1) PAL, RGT = H HD HST HCK1 HCK2 1 2 3 4 125 126 127 128 Horizontal display cycle (2.3.2) PAL, RGT = L HD HST HCK1 HCK2 1 2 3 4 125 126 127 128 Horizontal display cycle (2.4.1) VGA/NTSC/PC98, RGT = H HD HST HCK1 HCK2 1 2 3 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 - 18 - LCX016AM 3. 6-dot Simultaneous Sampling The horizontal shift register samples signals SIG1 to SIG6 simultaneously. 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 (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 panel 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 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. - 21 - LCX016AM Package Outline Unit: mm 3.7 0.1 Thickness of the connector 0.3 0.05 25.0 0.15 1.8 0.1 4 1 (62.0) 3 2 5 6 Incident light 8 Polarizing Axis Active Area 37.0 0.1 42.0 0.15 104.0 1.4 (20.0) 21.0 0.25 2.5 0.1 2.1 0.05 0.5 0.15 4.0 0.4 The rotation angle of the active area relative to H and V is 1. weight 7.6g 2.
