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

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.

Input Equivalent Circuits
To prevent static charges, protective diodes are provided for each pin except the power supplies. In addition,
protective resistors are added to all pins except video signal inputs. All pins are connected to Vss with a high
resistance of 1MΩ (typ.). The equivalent circuit of each input pin is shown below: (Resistor value: typ.)
