Abstract:
1. A control apparatus that controls a backlight providing light to a liquid crystal display panel, the control apparatus comprising: a controller configured to: (i) specify a response time required for a pre-change transmittance specified by image data of an image to be displayed on the liquid crystal display panel to become a post-change transmittance specified by image data of a subsequent image, subsequent to the image, to be displayed on the liquid crystal display panel, for each pixel of the liquid crystal display panel, based on the pre-change transmittance and on the post-change transmittance; (ii) derive a representative response time defined as a response time of an image in a frame, based on the response time specified for each of the pixels; and (iii) set an unlit time period of the backlight, between display of the image and the subsequent image, according to the representative response time so that the unlit time period of the backlight varies depending on a value of the representative response time.
