LCX007BK
E95733A64-ST
3.4cm (1.35-inch) Color LCD Panel
Description
The LCX007AK is a 3.4cm diagonal active matrix
TFT-LCD panel addressed by polycrystalline silicon
super thin film transistors with built-in peripheral driving
circuit, and it provides a full-color representation is
possible.
This panel provides a wide aspect ratio of 16:9,
such as those represented in HD. The built-in side-
black function also allows an aspect ratio of 4:3 in
the NTSC/PAL mode.
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
system and control signals.
Features
The number of active dots: 512,880 (1.35-inch; 3.4cm in diagonal)
Horizontal resolution: 400 TV lines
High optical transmittance: 4.0% (typ.)
High contrast ratio with normally white mode: 190 (typ.)
Built-in H and V drivers (built-in input level conversion circuit, 5V driving possible)
NTSC/NTSC-WIDE/HD (band: 20MHz) mode selectable
(PAL/PAL-WIDE mode also available through conversion of scanned dot numbers by an external IC)
Up/down and/or right/left inverse display function

Input Equivalent Circuit
To prevent static charges, protective diodes are provided for each pin except the power supply. In addition,
protective resistors are added to all pins except video signal input. All pins are connected to Vss with a high
resistance of 1M
(typ.). The equivalent circuit of each input pin is shown below: (The resistor value: typ.)
