Description

Waveshare 31738 includes a 3.97″ e-paper display in a version without a driver board, intended for use with external control systems via the SPI interface. The electrophoretic display technology enables image rendering using ambient light without backlight, reducing power consumption.

The display retains the last shown content without power, while energy is required only during refresh operations. Resolution of 800 × 480 pixels and 4 gray levels allow presentation of text and graphics in applications requiring good readability. A viewing angle exceeding 170° enables observation from different positions without contrast degradation.
