LCX023CMT
3.3cm (1.3-inch) Black-and-White LCD Panel
For the availability of this product, please contact the sales office.
Description
The LCX023CMT 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 LCX023ALB 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 (Dual Metal Shield) structure
realizes a high luminance screen. And new cross talk
free and ghost free structures 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. Also incorporating microlens can increase
efficiency of incident light.
Features
• Number of active dots: 786,432 (1.3-inch, 3.3cm in diagonal)
• XGA display
• SXGA viewable
• High optical transmittance: 30% (typ.)
• New high light resistance DMS (Dual Metal Shield) structure adopted
• Built-in-new cross talk free circuit and ghost 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
• Antidust glass package
Element Structure
• Dots: 1024 (H) × 768 (V) = 786,432
• Built-in peripheral driver using polycrystalline silicon super thin film transistors
Applications
• Liquid crystal data projectors
• Liquid crystal multimedia projectors
• Liquid crystal rear-projector TVs, etc.

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.)
