Abstract
Embodiments of the disclosed subject matter provide a device that includes a full color display. A camera may be disposed below the full color display. A controller may modify a video signal applied to one or more sub-pixels of the full color display based on a predicted degradation of the one or more sub-pixels, such that the modification is updated by the controller based on luminance data for the one or more subpixels acquired by the camera.
Claims20
A device comprising:
- a full color display comprising a plurality of pixels which have regions that are configured to emit light to render an image including a first type of pixels that are non-transparent and a second type of pixels that cover a camera lens and are transparent or semi-transparent, wherein each pixel has one or more sub-pixels, wherein the image is selected from the group consisting of:
- a static image or an image frame in a video;
- a camera including the camera lens is disposed below the full color display configured to directly receive light emitted from the one or more sub-pixels of at least one of the plurality of the second type of pixels with the transparent or semi-transparent regions which cover the camera lens that are configured to emit the light both towards the camera lens and away from the camera, wherein the camera is configured to measure luminance for the one or more sub-pixels of the second type of pixels based on the light directly received from the sub-pixel being measured;
- and
- a controller that correlates degradation performance of the first and second type of pixels and modifies a static image or one or more frames in a video signal applied to one or more sub-pixels of the full color display based on a predicted degradation of the one or more sub-pixels, such that the modification is updated by the controller based on luminance data for the one or more subpixels acquired by the camera.

A method comprising:
- analyzing, at a controller, a full color display to predict a degradation based on luminance and temperature history of a first type of pixels that are configured to emit light from a top surface away from a camera including a camera lens that is placed under the full color display wherein the first type of pixels are non-transparent, and a second type of pixels that are configured as transparent pixels that are disposed over the camera that is placed under the full color display, wherein the first type of pixels are configured to emit light from a top surface away from the camera, wherein the second pixels are configured to emit light away from the camera and also towards the camera, and wherein the camera is configured to receive light directly from one or more sub-pixels that are in optical communication with the camera lens of at least the second type of pixels;
- correlating, at the controller, degradation performance of the first type of pixels and the second type of pixels;
- setting, at the controller, the second type of pixels to a predetermined luminance using a predetermined drive current at predetermined time intervals, and measuring an actual luminance for the one or more sub-pixels of the second type of pixels based on the light directly received from the sub-pixel being measured using the camera;
- determining, at the controller, an actual degradation of the second type of pixels based on the measured actual luminance for the one or more sub-pixels of the second type of pixels acquired by the camera;
- comparing, at the controller, the predicted degradation and the actual degradation of the second type of pixels based on a history of the second type of pixels;
- modifying, at the controller, the prediction for degradation of the second type of pixels based on the comparison of the comparison of the predicted degradation and the actual degradation;
- modifying, at the controller, the prediction for the degradation of the first type of pixels based on the correlation of the degradation performance of the first type of pixels and the second type of pixels;
- and
- modifying a static image or one or more frames in a video signal applied to one or more sub-pixels of the full color display based on a predicted degradation of the one or more sub-pixels.

A method comprising:
- analyzing, at a controller, a full color display to predict a degradation based on luminance and temperature history of one or more sub-pixels of pixels that include first type of pixels that are configured to be non-transparent and a second type of pixels that are configured as transparent pixels that are disposed over a camera having a camera lens that is placed under the full color display, wherein the first type of pixels are configured to emit light from a top surface away from the camera, wherein the second type of pixels are configured to emit light both towards and away from the camera, wherein the one or more sub-pixels are in optical communication with the camera lens, and wherein the camera is configured to measure luminance for the one or more sub-pixels of the second type of pixels based on the light directly received from the sub-pixel being measured;
- correlating, at the controller, degradation performance of the first type of pixels and the second type of pixels;
- modifying, at the controller, the predicted degradation of the first type of pixels that are the transparent pixels based on the measured luminance and thermal temperature history acquired by the camera for one or more sub-pixels of the second type of pixels that are the transparent pixels;
- and
- modifying, at the controller, modifying a static image or one or more frames in a video signal applied to one or more sub-pixels of the full color display that is not visible by the camera and at least one of the transparent pixels based on the modified predicted degradation.
