  • Patent number: 7495590
    Abstract: A technique for removing vertical stripe artifacts generated in a Liquid Crystal Display (LCD) panel, more particularly a technique for compensating for and removing an inter-channel offset voltage of a column driver, which causes the vertical stripe artifacts, is disclosed. An offset voltage generated in each channel for driving each pixel of the LCD panel is detected for a whole signal path and offset voltages detected for all channels are compared and extracted according to a given timing sequence by a common signal comparator, thereby preventing the offset of the detection comparator and reducing a chip size of the column driver in contrary to the prior art. Moreover, an inter-channel offset voltage is detected in a digital circuit mode, thereby compensating for process variations in a semiconductor chip manufacturing process in circuit terms.
