Abstract
A display having an area of non-transparent pixels, an area of transparent pixels, a camera positioned behind the transparent pixels to capture an image when light passes through the transparent pixels, and a display controller for driving the non-transparent pixels at a first brightness and driving the transparent pixels at a second brightness greater than the first brightness during image capture by the camera.
Claims17
A method of controlling illumination of a display having non-transparent pixels and transparent pixels that define a transparent area of the display behind which a camera is positioned, comprising:
- driving the non-transparent pixels at a first brightness;
- driving the transparent pixels at a second brightness greater than the first brightness during a first portion of a video display frame in which the camera is not performing image capture, using gate lines that respectively extend from opposite sides of the display towards each other into the transparent area and using a source line, the gate lines electrically isolated from each other in the transparent area, the gate lines and the source line comprising transparent material in the transparent area and non-transparent material outside the transparent area, and the gate lines and the source line having respective terminating ends located in the transparent area and that comprise the transparent material in the transparent area;
- and
- disabling the transparent pixels during a second portion of the video display frame in which the camera is performing image capture.
A display comprising:
- an area of non-transparent pixels;
- an area of transparent pixels;
- a camera positioned behind the transparent pixels to capture an image when light passes through the transparent pixels;
- a display controller to drive the non-transparent pixels at a first brightness, drive the transparent pixels at a second brightness greater than the first brightness when the camera is not capturing the image, and disable the transparent pixels when the camera is capturing the image;
- a plurality of source lines including a first source line composed of a non-transparent material and a transparent material, and a second source line composed of the non-transparent material;
- a first set of gate lines including a first gate line composed of the non-transparent material and the transparent material, and a second gate line composed of the non-transparent material;
- and
- a second set of gate lines including a third gate line composed of the non-transparent material and the transparent material, and a fourth gate line composed of the non-transparent material,
- wherein the transparent material of the first source line, the first gate line, and the third gate line define a transparent area of the display,
- wherein the first gate line and the third gate line extend from opposite sides of the display towards each other into the transparent area,
- wherein respective terminating ends of the first gate line, the third gate line, and the first source line are located in the transparent area and comprise the transparent material in the transparent area,
- wherein the first gate line and the third gate line are electrically isolated from each other in the transparent area,
- wherein the first gate line and the third gate line comprise the transparent material in the transparent area and the non-transparent material outside the transparent area,
- and wherein the camera is disposed adjacent the transparent material of the first source line, the first gate line, and the third gate line.
A non-transitory computer-readable medium comprising instructions to direct a processor to:
- capture images by a camera positioned behind transparent pixels of a display having both non-transparent pixels and the transparent pixels;
- disable the transparent pixels during image capture by the camera;
- drive the non-transparent pixels at a first brightness;
- and
- drive the transparent pixels at a second brightness greater than the first brightness when not disabled using gate lines that respectively extend from opposite sides of the display towards each other into a transparent area and using a source line, the gate lines electrically isolated from each other in the transparent area, the gate lines and the source line comprising transparent material in the transparent area and non-transparent material outside the transparent area, and the gate lines and the source line having respective terminating ends located in the transparent area and that comprise the transparent material in the transparent area.
