摘要:
A display device having a display matrix including a pixel border of width x and located around the edge locations of the matrix for improved viewability. The pixels of the border are “dummy pixels” each containing a red, a green and a blue subpixel. Each subpixel has a color filter and is manufactured with a “dummy” transistor which operates to fix open the subpixels thereby allowing a predetermined amount of “white” color brightness through the dummy pixels. The pixel border is useful for increasing viewability of characters that are displayed along the edge of the LCD matrix area in which images are generated from a frame buffer memory.
