ABSTRACT:
A driving network for a TFEL panel includes a frame capture buffer for flat panels having split-screen architecture to increase the video bandwidth and to allow for a high frame refresh rate without changing the video input rate. Input serial video data is converted to parallel data bits and latched at a predetermined clock rate. The latched data bits are transferred to appropriate buffer memories, one for each independently driven portion of the screen. Writing to the buffer memories and reading data out from the buffer memories occurs at asynchronous rates so that data in smaller bytes may be clocked in at a higher frequency and read out of the buffer memories in larger bytes at a lower frequency. Since data may be processed onto flat screen arrays in multiple bits per clock pulse, the frame repetition rate limitations inherent in processing serial input video data are avoided.
