TFT LCD display module YX20035A

transflective240 x 3202"

Overview
The YX20035A is a 2.0-inch transflective TFT LCD module engineered for applications that demand outdoor readability, low power consumption and stable performance across varied lighting conditions. Equipped with the ST7789V driver and a 16-bit MCU interface, the module offers a 240×320 RGB resolution and compact mechanical dimensions suitable for embedded industrial and portable devices.

Transflective Technology
The transflective optical structure combines reflection and backlight modes: ambient light improves visibility and reduces backlight usage in bright outdoor environments, while the integrated white LED backlight ensures clear, vivid images indoors or in low light. This dual-mode approach enhances battery life and usability in field applications.
