ANDpSi025TD-LED-KIT

2.5” Active Color

TFT LCD Color Monitor

The ANDpSi025TD-LED-KIT is an 640 x 240 active matrix color

TFT LCD Module with Digital and Analog Interface that utilizes

new low temperature poly-silicon (p-Si) technology to provide

brighter, thinner and lighter display with high resolution. Both of

horizontal and vertical scan are reversible and controlled by the

serial interface commands. The product is designed for the

requirement of the green product, and the specification complies

with Toppoly’s “Green Product Chemical Substance Specification

Standard Hand Book”. All these features making it ideal for

portable applications including personal digital assistants (PDAs),

medical instruments and test & measurements instruments.

Features

• p-Si construction with drivers on glass

• High luminance

• Digital and Analog Interface

• 16 Million/Full Color

• Slim (2.53 mm) and lightweight design

• Transmissive type. FIxed current LED backlight

• RoHS Compliant
