Description

Square TFT Display 4 Inch SPI&MCU 320x320 Dots 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.
