Description
The LCX017DLT is a 4.6cm diagonal active matrix
TFT-LCD panel addressed by polycrystalline silicon
super thin film transistors with a built-in peripheral
driving circuit. Use of three LCX017DLT 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.
Features
Number of active dots: 786,432 (1.8 Type, 4.6cm in diagonal)
Accepts the computer requirements of XGA, SVGA, VGA, NTSC and PAL
Supports SXGA with simple display
High optical transmittance: 23% (typ.)
New high light resistance DMS (Dual Metal Shield) structure adopted
New cross talk free and ghost free structures
High contrast ratio with normally white mode: 350 (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 used
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 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 V
SS
with a
high resistor of 1M
(typ.). The equivalent circuit of each input pin is shown below: (Resistance value: typ.)
