►Black and white, 1-bit per pixel
►Serial interface
►1-bit internal memory in panel
►Super low power consumption
WFM0103A2TABASNN000 is a 1.03-inch reflective MIP (Memory in Pixel) display module with a 128x128 resolution and SPI interface. The display operates using ambient light, supporting visibility in bright environments, including outdoor conditions.
An integrated LED back light is included to support visibility under low ambient light conditions. Due to the reflective display structure, the front light functions as a supplementary light source rather than the primary illumination source.
This module is designed for ultra-low power consumption, making it suitable for battery-powered applications requiring efficient power management. The compact module size of 24.29 x 28.66 x 1.78 mm, Hard Coat front polarizer, and operating temperature range of -20°C to +70°C support integration into compact electronic systems.
