Abstract: 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. In particular, the border can be several pixels wide, e.g., 1<x<5. In one embodiment, the border region is two pixels wide and surrounds a display region in which images are generated from a frame buffer memory. Both the border region and the display region are implemented using a negative mode passive display matrix using liquid crystal display (LCD) technology. The pixels of the border are controllable between an on state and an off state and have an adjustable threshold voltage level. In one embodiment, the display screen is a negative mode display in which the pixels are normally black when off. The pixel border is useful in providing contrast in display modes having a white background with black characters displayed therein.

Abstract: One embodiment of the present invention provides a transflective display in which a border area adjacent to an active area has a reflectivity that is substantially the same as the active area when the display is turned off. This display includes a polarizer layer, a color filter glass (CFG) layer, a liquid crystal layer, and a reflector layer. The CFG layer contains color filters in the active area, while the border area of the CFG layer is designed to have a reflectivity that is substantially the same as the active area when the display is turned off.
