4.1cm (1.6-inch) LCD Panel (with microlens)

Description

The LCX021AM is a 4.1cm diagonal active matrix

TFT-LCD panel addressed by polycrystalline silicon

super thin film transistors with built-in peripheral driving

circuit. This panel allows full-color representation

without color filters through the use of a microlens.

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 by incorporating a high

luminance screen, 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. 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 SVGA 4:3/PC98

8:5 data signals

by changing the active area according to the type of

input signal.

"PC98" is a trademark of NEC Corporation.

Features

· The number of active dots: 1,456,000 (1.6-inch; 4.1cm in diagonal)

· Supports SVGA (804

604) and PC98

(804

500)

· Effective aperture ratio: 70% (reference value)

· Built-in cross talk free and ghost free circuits

· High contrast ratio with normally white mode: 150 (typ.)

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 video signal inputs. All pins are connected to V

with a high

resistor of 1M

(typ.). The equivalent circuit of each input pin is shown below: (The resistor value: typ.)
