Displays with partial transparent areas

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.

What is claimed: 
     
         1 . A method of controlling illumination of a display having non-transparent pixels and transparent pixels, 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 the video display frame; and   disabling the transparent pixels during a second portion of the video display frame.   
     
     
         2 . The method of  claim 1 , wherein the difference in brightness between the second brightness and first brightness is proportional to the duty cycle of the first portion to the second portion. 
     
     
         3 . The method of  claim 1 , wherein the duty cycle of the first portion to the second portion is 1:1 and the second brightness is approximately twice the first brightness. 
     
     
         4 . The method of  claim 1 , wherein the duty cycle of the first portion to the second portion is 1:2 and the second brightness is approximately 50% greater than the first brightness. 
     
     
         5 . 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; and   a display controller to drive the non-transparent pixels at a first brightness and drive the transparent pixels at a second brightness greater than the first brightness during image capture by the camera.   
     
     
         6 . The display of  claim 5 , further comprising:
 a plurality of source lines including a first source line composed of a non-transparent portion and a transparent portion, and a second source line composed of the non-transparent portion;   a first set of gate lines including a first gate line composed of the non-transparent material and the transparent portion, and a second gate line composed of the non-transparent portion;   a second set of gate lines including a third gate line composed of the non-transparent material and the transparent portion, and a fourth gate line composed of the non-transparent material, the transparent portion of the first source line, the first gate line, and the third gate line define a transparent area of the display;   wherein the camera is disposed adjacent the second portion of the source line, the second portion of the first gate line, and second portion of the second gate line.   
     
     
         7 . The display of  claim 6 , wherein the first set of gate lines is electrically isolated from the second set of gate lines. 
     
     
         8 . The display of  claim 6 , further including a source driver to control the source lines, a first gate driver to control the first set of gate lines, and a second driver to control the second set of gate lines. 
     
     
         9 . The display of  claim 5 , wherein the second brightness is approximately twice the first brightness. 
     
     
         10 . The display of  claim 5 , wherein the second brightness is approximately 50% greater than the first brightness. 
     
     
         11 . The display of  claim 8 , wherein the first gate driver controls the first gate line independently from the second gate driver to control the second gate line. 
     
     
         12 . The display of  claim 6 , further including a gap between the first gate line and the second gate line. 
     
     
         13 . A non-transitory computer-readable medium comprising instructions to direct a processor to:
 capture images by a camera positioned behind non-transparent pixels of a display having both non-transparent pixels and 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.   
     
     
         14 . The non-transitory computer-readable medium of  claim 13  including instructions to direct the processor to capture images at duty cycle of 1:1 and drive the transparent pixels to twice the first brightness. 
     
     
         15 . The non-transitory computer-readable medium of  claim 13  including instructions to direct the processor to capture images at duty cycle of 1:2 and drive the transparent pixels to approximately 50% greater than the first brightness.
