LCX037BLT
3.4cm (1.35 Type) Black-and-White LCD Panel
Description
The LCX037BLT is a 3.4cm diagonal active matrix
TFT-LCD panel addressed by polycrystalline silicon
super thin film transistors with a built-in peripheral
driving circuit. Use of three LCX037BLT panels
provides a full-color representation. The striped
arrangement suitable for data display is capable of
displaying fine text and vertical lines.
The adoption of a new developed dot-line inverse
drive system, CMP (Chemical Mechanical Polish)
and OCS (On Chip Spacer) 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.
Features
Number of active dots: 1,049,088 (1.35 Type, 3.4cm in diagonal)
High optical transmittance: 16% (typ.)
Dot-line inverse drive circuit

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.)
