Abstract
A field emission device (10) includes a video memory device (12) that receives video data in parallel for each of three colors red, green, and blue. The video memory device (12) provides the video data in color sequential manner to a controller (14). The controller (14) provides appropriate control and data signals in response to the video data to drive a field emission device display (22). The video memory device has a first storage area (30) for a first color (red), a second storage area (32) for a second color (green), and a third storage area for a third color (blue). The second storage area (32) has capacity to store all of the second color of a frame, the first storage area (30) is two-thirds the size of the second storage area (32), and the third storage area (34) is one-third larger than the second storage area (32). The different sizes of the respective storage areas allows for 100% use of memory space without waste. Simultaneous writing into and reading from each storage area is performed in such a manner as to not lose any of the video data.
