Abstract:
A method for displaying a color image on a liquid crystal panel including a plurality of pixels located in a matrix, said method comprising the steps of:selecting a color by pointing a first position with a pointing device in a color selecting portion on the liquid crystal panel; detecting the first position on the liquid crystal panel by a detector; converting the color into color data by a color designator circuit; storing the color data in N storage regions of a memory device where each of the N storage regions has a number of addresses equal to a number of pixels in the matrix, so that 2N colors are addressed for the liquid crystal panel; pointing a second position with the pointing device on the liquid crystal panel after selecting the color; detecting the second position on the liquid crystal panel by the detector; outputting the position as an output signal having X-coordinate data and Y coordinate data; generating a first address from the X-coordinate data and Y-coordinate data; converting the color data into video data; and displaying the video data by an output circuit in accordance with the first address.
