FIELD-SEQUENTIAL COLOR MODE TRANSITIONS

摘要

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for selecting an operational mode of a reflective display device from a plurality of operational modes that include at least one field-sequential color mode. The operational mode may be selected based, at least in part, on ambient light data. The ambient light data may include ambient light intensity data, ambient light spectrum data and/or ambient light direction data. The operational mode may be selected based, at least in part, on other criteria, such as display application type and/or battery state data.

主权项

1. A reflective display device, comprising:
a front light including light sources having a first range of spectral emissions and a second range of spectral emissions; a reflective display including a first plurality of reflective sub-pixels having a first spectral reflectance range, a second plurality of reflective sub-pixels having a second spectral reflectance range and a third plurality of reflective sub-pixels having a third spectral reflectance range, each of the first, second and third spectral reflectance ranges overlapping the first range of spectral emissions and the second range of spectral emissions; a sensor system including an ambient light sensor; and a control system configured to:
receive ambient light data from the ambient light sensor;select, based at least in part on the ambient light data, a current operational mode from a plurality of operational modes, the plurality of operational modes including at least one field sequential color (FSC) operational mode; andcontrol the front light and the reflective display according to the current operational mode.
