OPTICAL SYSTEM AND METHOD TO MIMIC ZERO-BORDER DISPLAY
A system and methods to extending the overall display area for a device. At or near the borders of a device, pixel pitch between adjacent pixels may be increased such that overall pixel placement may be provided closer to a border of a display of a device. In one embodiment, pixel drive circuitry may be located in the spacing between adjacent pixels. Additionally, various optical systems and techniques may be utilized to provide an appearance of a lack of a border around the display such as decreasing the size of border pixels, overdriving the border pixels, or utilizing a light pipe on a surface above the border pixels.
1 . An electronic device, comprising:
a display comprising a plurality of pixels, wherein a first distance between a first pixel and its neighboring second pixel is greater than a second distance between a third pixel and its neighboring fourth pixel; and
drive circuitry configured to drive the plurality of pixels, wherein a drive circuit element of the drive circuitry is located in the first distance between the first pixel and its neighboring second pixel.
2 . The electronic device of claim 1 , wherein the first pixel and its neighboring second pixel are located in a border region of the display.
3 . The electronic device of claim 2 , wherein the each pixel in the border region of the display having a neighboring pixel directly adjacent thereto in a common row is configured to generate light of a different color than its neighboring pixel.
4 . The electronic device of claim 2 , wherein the each pixel in the border region of the display having a neighboring pixel directly adjacent thereto in a common column is configured to generate light of a different color than its neighboring pixel.
5 . The electronic device of claim 1 , wherein the third pixel and the fourth pixel are located in a central region of the display.
6 . The electronic device of claim 1 , wherein the display comprises an organic light emitting diode display.
7 . An electronic device, comprising:
