LCX034ALT
1.8cm (0.7 Type) Black-and-White LCD Panel
Description
The LCX034ALT is a 1.8cm diagonal active matrix
TFT-LCD panel addressed by polycrystalline silicon
super thin film transistors with a built-in peripheral
driving circuit. Use of three LCX034ALT 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 realizes 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 SVGA/VGA/PC98∗2 data signals by
changing the active area according to the type of
input signal. In addition, double-speed processed
NTSC/PAL can also be supported.
∗1 Dual Metal Shield
∗2 “PC98” is a treadmark of NEC Corporation.
Features
• Number of active dots: 485,000 (0.7 Type, 1.8cm in diagonal)
• Accepts the computer requirements of SVGA (804 × 604), VGA (644 × 484) and PC98 (644 × 404) platforms
• Supports NTSC (644 × 484) and PAL (762 × 572) by processing the video signal at double speed
• High optical transmittance: 13% (typ.)
• Built-in cross talk free circuit and ghost free circuit
• High contrast ratio with normally white mode
• Built-in H and V drivers (built-in input level conversion circuit, 5V driving possible)
• Up/down and/or right/left inverse display function
• Dust-proof glass used
Element Structure
• Dots: 804 (H) × 604 (V) = 485,616
• Built-in peripheral driver using polycrystalline silicon super thin film transistors
Applications
• Liquid crystal data projectors
• Liquid crystal projectors, etc.
