Abstract
An electronic device includes a display panel. The display panel includes a number of pixels, each of which includes a driving thin-film-transistor (TFT) and a light-emitting diode. Compensation circuitry external to the display panel applies offset data to pixel data for each pixel of the plurality of pixels before the pixel data is provided to the plurality of pixels.
Claims20
An electronic device, comprising:
- a display panel, comprising:
- a plurality of pixels, each pixel of the plurality of pixels comprising:
- a driving thin-film-transistor (TFT) configured to receive pixel data of a respective pixel;
- and
- a light-emitting diode configured to emit light based on the pixel data provided to the respective pixel;
- and
- compensation circuitry, wherein the compensation circuitry is configured to apply offset data to the pixel data for each pixel of the plurality of pixels, prior to provision of the pixel data to the respective pixel.

A method of operating an electronic device with a display panel, comprising:
- applying offset data to pixel data for each pixel of a plurality of pixels of the display panel of the electronic device, prior to provision of the pixel data to the plurality of pixels, resulting in compensated pixel data;
- applying, at a driving thin-film-transistor (TFT) of each of the plurality of pixels, compensated voltage data that is based upon the compensated pixel data, resulting in a compensated current;
- and
- applying the compensated current to a corresponding diode of each of the plurality of pixels.
1 more element
An electronic display circuitry, comprising:
- a display panel;
- and
- compensation circuitry configured to apply offset data to pixel data for each pixel of a plurality of pixels of the display panel, prior to provision of the pixel data to the plurality of pixels, such that a compensated voltage is applied to a driving thin-film-transistor (TFT) of each pixel, resulting in a compensated current that is applied to a light-emitting diode of each pixel.
