WFM0108A2TAJASNN000 is a 1.08-inch reflective MIP (Memory in Pixel) display module featuring a 160×68 resolution and SPI interface. The display adopts a reflective active-matrix structure with slightly transmissive characteristics, providing good readability under ambient light conditions.
Each pixel integrates 1-bit memory, enabling image data to be stored directly within the panel and allowing the displayed image to be maintained without continuous refresh. The module supports arbitrary line updates, so only modified areas need to be refreshed, significantly reducing overall power consumption.
The module features a monolithic design, resulting in a thin, lightweight, and compact form factor. A HardCoat front polarizer is applied to improve surface durability for portable and low-power device integration.
This display is suitable for applications requiring ultra-low power operation, stable image retention, and reliable visibility in bright ambient environments.
