    摘要: A video controller for controlling at least two video displays incorporates a video memory for storing first and second video frames of interleaved pixel data. A video memory controller connected to the video memory sequentially reads data for a first pixel from the first video frame and data for a second pixel from the second video frame. Each pixel data is in turn transferred to a look-up table connected to the video memory controller which converts the first and second pixel data to first and second display data. A selector coupled to the look-up table alternately routes the first display data to one video display and routes the second display data to the other video display.

    摘要: A method and apparatus for compensating crosstalk in liquid crystal displays is disclosed which involves applying boost voltages to the rows and columns of the display in proportion to the number of ON pixels in a row or column, the number of transition between "ON-and-OFF" or "OFF-and-ON" in each column, and the position of the pixel in a row. "Boost" voltages are applied to each row as it is being actively scanned to provide horizontal crosstalk compensation, while "boost" voltages are applied to each column during the vertical retrace interval of the display sequence to provide vertical crosstalk compensation. In a preferred embodiment, the vertical crosstalk compensation is determined during the vertical retrace interval over several flames.
