LCX029CPT
2.3cm (0.9 Type) Black-and-White LCD Panel
Description
The LCX029CPT is a 2.3cm diagonal active matrix
TFT-LCD panel addressed by polycrystalline silicon
super thin film transistors with a built-in peripheral
driving circuit. Use of three LCX029CPT 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 DMS∗1 structure and high light
resistance structure realize a high luminance screen.
And cross talk free circuit and ghost free circuit
contribute to high picture quality.
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 S-XGA 5:4 and PC-98 8:5 data signals
by changing the active area according to the type of
input signal.

Input Equivalent Circuit
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 the video signal inputs. All pins are connected to VSS with a
high resistor of 1MΩ (typ.). The equivalent circuit of each input pin is shown below: (Resistance value: typ.)
