LCX019AM
3.4cm (1.32-inch) LCD Panel (with microlens)
For the availability of this product, please contact the sales office.
Description
The LCX019AM is a 3.4cm 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.
This panel has an aspect ratio of 4:3 and supports
NTSC/PAL display.
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.
Features
• The number of active dots: 576,000 (1.32-inch; 3.4cm in diagonal)
• Horizontal resolution: 600TV lines
• Effective aperture ratio: 70% (reference value)
• High contrast ratio with normally white mode: 200 (typ.)
• Built-in H and V drivers (built-in input level conversion circuit, 5V driving possible)
• Supports NTSC
(PAL mode also available through conversion of scanned dot numbers by an external IC)
• Up/down and/or right/left inverse display function
Element Structure
• Dots: 1199.5 (H) × 480 (V) = 575,760
• Built-in peripheral driver using polycrystalline silicon super thin film transistors.
Applications
Liquid crystal projectors, etc.

Level Conversion Circuit
The LCX019AM has a built-in level conversion circuit in the clock input unit on the panel. The input signal level
increases to HVDD or VVDD. The VCC of external ICs are applicable to 5 ± 0.5V.

1. Contrast ratio
Contrast Ratio (CR) is given by the following formula (1).
CR =
L (White)
L (Black) ...... (1)
L (White): Surface luminance of the TFT-LCD panel at the input signal amplitude VAC = 0.5V
L (Black): Surface luminance of the panel at VAC = 4.5V
Both luminosities are measured by System I.
