LCX021AM
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

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
SS
with a high
resistor of 1MΩ (typ.). The equivalent circuit of each input pin is shown below: (The resistor value: typ.)
