Project Description

VIS028TN02 is a 2.8 inch TFT LCD screen module model that adopts IPS type LCD with 240*320 resolution. CTP (Capacity Touch Panel) or RTP(Resistive Touch Panel) can be added according to user requirements. Based on the product’s wide view angle and excellent storage and operating temperature range, this 2.8 inch TFT LCD IPS module can be widely used in smart homes, pos machines, industrial instruments (meters), and small medical equipment and other products. We can guarantee a stable supply of this TFT screen module throughout the life cycle of your product.

FPCA shape alignment, polarizer material, and backlight brightness can be adjusted according to your needs.

In order to meet the needs of different customers, we also provide a 2.8-inch TN type TFT LCD display. If you need, please contact us.

Other 2.8 inch TFT LCD screen module (LCM) models that can be replaced by VIS028TN02 are ET028VG01, TXW280047B0-RTP, UE028QV-RH40, etc.
