Abstract
Examples of when to perform a flash update to reset pixels of a display device are described. In some implementations, a pixel threshold may be determined based at least partly on a temperature associated with a display device. A counter may be modified based at least partly on a number of pixels changed by a plurality of updates sent within a predetermined period of time to the display device. A flash update of the display device may be performed based at least partly based on determining that the counter satisfies the pixel threshold.
Claims20
One or more non-transitory computer-readable media comprising instructions executable by one or more processors to perform acts comprising:
- determining a number of pixels changed by a plurality of updates sent within a predetermined period of time to an electronic paper display;
- modifying a counter based at least partly on the number of pixels changed by the plurality of updates;
- and
- performing a flash update of the electronic paper display based at least partly on:
- a temperature associated with the electronic paper display, and
- the number of pixels changed by the plurality of updates.
An electronic book (eBook) reader comprising:
- an electronic paper display;
- a temperature sensor to determine a temperature associated with the electronic paper display;
- a display controller;
- one or more processors;
- and
- one or more non-transitory computer-readable media to store instructions executable by the one or more processors to perform acts comprising:
- determining a number of pixels changed by a plurality of updates received by the display controller;
- and
- instructing the electronic paper display to perform a flash update based at least partly on:
- the temperature associated with the electronic paper display;
- and
- the number of pixels changed by the plurality of updates.
A method performed under control of one or more processors configured with instructions to perform acts comprising:
- determining a number of pixels changed by a plurality of updates sent to an electronic paper display;
- measuring a temperature associated with the electronic paper display;
- and
- sending an instruction to the electronic paper display to perform a flash update based at least partly on:
- the number of pixels changed by the plurality of updates;
- and
- the temperature associated with the electronic paper display.
