Three colour display modules

Four high resolution three colour TFT active matrix Electronic Paper Display modules have been launched by Pervasive Displays. The devices, which feature internal timing controllers, measure 1.54, 2.13, 2.66 and 2.71in and are said to be suitable for use in sectors such as retail, public displays and healthcare.

The modules feature black, white and red E Ink display panels and each has a resolution of 103pixel/in. Legible in natural light, the bistable display consumes little power to update an image and no power to maintain it. This means a display can operate for months from a single battery.

The integrated chip-on-glass timing controller is said to cut component cost and application development time. A one time programmable look up table holds driving waveforms, which control colour changes. As well as the integrated timing controller, the modules also feature a booster circuit.
