Description

WAA0290A2ABA8NXXX000 is a 2.9" Electronic Paper Display (EPD) with capacitive touch panel. The display is capable of showing black-and-white images with full 1-bit display capability. The 2.9-inch active area contains 296x128 pixels. The module uses a TFT array to drive the electrophoresis display, with integrated circuits including gate driver, source driver, MCU interface, timing controller, oscillator, DC-DC converter, SRAM, LUT, and VCOM control. The module can be used in portable electronic devices, such as in Electronic Shelf Label (ESL) systems.
