Title:
COLOR DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/079641
Kind Code:
A1
Abstract:
Disclosed is a color display device comprising a total fluctuation calculation unit (23) contained in a display control circuit (200). On the basis of a display data signal (DAT) from the outside, the total fluctuation calculation unit (23) calculates the total of the quantities of potential fluctuations of a driving video signal to be applied for one frame to each video signal line. For a pixel forming portion, to which a display data signal (DATp) (corresponding to a next display line of one frame before) received from a frame memory (22) is fed, a data correction unit (24) makes a correction to compensate the influence which is caused by the potential fluctuations of adjacent another video signal line not connected with the image forming portion. Thus, the color display device of a delta array type can reduce or eliminate a transverse streak, which is caused by the potential fluctuations of said another video signal line, by the simple constitution.
