TFT LCD 4 Inch 320x320 Square Type MCU&SPI Interface 3.3V
Product Introduction
SAEF TECHNOLOGY SF-TO400DX-8979A-CT TFT LCD display module is a transmissive type color active matrix
TFT(Thin Film Transistor) liquid crystal display (LCD) that uses
amorphous silicon TFT as a switching device. This module is
composed of a TFT LCD module, a driver circuit, and a back-light
unit. the resolution of a 4” contains 320 (RGB)X 320 dots, and it
can display up to 262k color. SF-TO400DX-8979A-CT TFT LCD model supports MCU and SPI interface; the supply voltage
(VCC) of driving LCD panel is from is 2.7V to 3.6V. Typical value
is 3.3V.
SF-TO400DX-8979A-CT can be operating at temperatures from -20℃ to +70℃; its storage
temperatures range from -30℃ to +80℃. the LCD module is with PCAP
capacitive touch screen, It is great for automation, GPS, medical
equipment, industrial device, security equipment white goods, smart
home applications, IoT System, car equipment, car dashboard, car
audio, car clock, car door display system, water ionizer, which
requires TFT display in high quality and colorful image.
