Patent number: 7466310Abstract: A line compensated overdriving circuit for use in a color sequential display is disclosed. The line compensated overdriving circuit comprises an overdrive unit, a line compensation generator, and a line compensated overdrive (LCO) processor. The overdrive unit receives previous data and present data to output overdrive data. The line compensated generator receives a line position of each pixel to output a line compensated factor, and the LCO processor receives the line compensated factor and the overdriven data to generate compensated data for the pixel. Thus, the line compensated overdriving circuit can eliminate the spatial intensity variations associated with the conventional color sequential displays.Type: GrantFiled: December 13, 2004Date of Patent: December 16, 2008Assignee: Himax Technologies LimitedInventors: Yu-Chu Yang, Ming-Yeong Chen
