LCX012BL
E96512-ST
3.3cm (1.3-inch) Black-and-White LCD Panel
Description
The LCX012BL is a 3.3cm 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 LCX012BL provides a full-color represen-
tation. The striped arrangement suitable for data
projectors is capable of displaying fine text and
vertical lines.
The adoption of advanced on-chip black matrix
realizes high picture quality without cross talk by
incorporating 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.
Using Sony's timing generator "CXD2442Q" sends
timing signal necessary for LCD panel drive by
identificating computer supporting VGA automati-
cally, and supports double-speed processed
NTSC/PAL.
Features
The number of active dots: 312,000 (1.3-inch; 3.3cm in diagonal)
Accepts the computer requirements of VGA platform (640 x 480)
High optical transmittance: 25% (typ.)
Supports NTSC/PAL by processing the video signal at double speed
Built-in cross talk free circuit
High contrast ratio with normally white mode: 250 (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: 644 (H)
484 (V) = 311,696
Built-in peripheral driver using polycrystalline silicon super thin film transistors.
Applications
Liquid crystal data projectors
Liquid crystal projectors, etc.

Input Equivalent Circuit
To prevent static charges, protective diodes are provided for each pin except the power supply. In addition,
protective resistors are added to all pins except video signal input. All pins are connected to V
SS
with a high
resistance of 1M
(typ.). The equivalent circuit of each input pin is shown below: (The resistor value: typ.)

The typical value of the common pad voltage may lower its suitable voltage according to the set
construction to use. In this case, use the voltage of which has maximum contrast as typical value. When the
typical value is lowered, the maximum and minimum values may lower.

Input a uniformity improvement signal PSIG in the same polarity with video signals SIG1 to 6 and which is
symmetrical to VVC. Also, the rising and falling of PSIG are synchronized with the rising of PCG pulse, and
the rise time trPSIG and fall time tfPSIG are suppressed within 800ns (as shown in a diagram below).
