Title:
表示制御装置および表示装置
Document Type and Number:
Japanese Patent JP7302506
Kind Code:
B2
Abstract:
To suppress image sticking and color shift due to a deviation of correction in pixels whose cumulative light emission times become equal to or greater than a prescribed time.SOLUTION: A display control unit 3 sets a pixel with the longest cumulative light emission time in a pixel group made of self-luminous elements constituting a display panel 2 as a high frequency pixel, and sets a residual pixel group different from the high frequency pixel in the pixel group as a low frequency pixel group. The display control unit 3 includes a light emission adjustment part 35, and causes the display panel 2 to display a corrected video in which the high frequency pixel is turned off and only the low frequency pixel group is turned on together with the normal video display so as to prevent a user from visually recognizing the corrected video. With this, a difference in the cumulative light emission times between the low frequency pixel group and the high frequency pixel becomes small. Even if a deviation of correction occurs, since the low frequency pixel group and the high frequency pixel have the same level of deviations, image sticking and color shift due to the deviation of correction is suppressed.SELECTED DRAWING: Figure 1
