480x800 4" Resistive Touchscreen TFT Display
Part Number: SF-TC397H-8783A-T
SF-TC397H-8783A-T is a 4 inch TFT-LCD module.It is composed of a
TFT-LCD panel,driver IC,FPC, a back light unit.The 4" display area
contains 480 X(RGB)X 800pixels and can display up to 262K
colors.This product accords with RoHS environmental criterion.
This graphic TFT display module is a 3.97" diagonal, full-color
TFT. This TFT LCD is low-power, uses a white LED backlight, and has
an integrated resistive touch-screen with the connection brought
out to the main TAB connector for the display. This LCD TFT has an
onboard controller and 2.8v single voltage for supply and logic. It
uses an RGB interface, specified via connections to the display.
This module looks awesome! Displaying all information in
full-color. It widely used in coffee machine, micro-wave oven,
scanner, home automation, access control system, monitoring
equipment, analyzers, security system, garden irrigation system,
etc.
