Description
1.9-inch Touch Screen TFT LCD
The SHENZHEN TECHSTAR ELECTRONICS INCORPORATED CO., LTD Â SF-TC190ASJ-8977A-CT TFT LCD display module is a transmissive type color active matrix TFT (Thin Film Transistor) liquid crystal display (LCD) that utilizes amorphous silicon TFT as a switching device. This module comprises a TFT LCD module, a driver circuit, and a backlight unit. PPI (Pixel Per Inch) refers to Pixels Per Inch, with the resolution of a 1.9-inch screen containing 170 (RGB) x 320 dots (170 horizontal by 320 vertical pixels array) and capable of displaying up to 262k colors. The SF-TC190ASJ-8977A-CT TFT LCD model supports SPI and RGB interfaces; the supply voltage (VCC) for driving the LCD panel ranges from 2.4V to 3.3V, with a typical value of 2.8V. It can be utilized in embedded systems, automation, GPS, medical equipment, industrial devices, and security equipment requiring TFT displays for high-quality and colorful imagery.
SF-TC190ASJ-8977A-CT is an IPS-LCD type TFT with a brightness of 330 cd/m2 (typical value). The brightness can be customized to achieve 1000 nits. Please contact our sales team for more details. It can operate at temperatures ranging from -20℃ to +70℃, with storage temperatures ranging from -30℃ to +80℃.
