Abstract: A display device includes: an image display panel having a display area; a light source device configured to illuminate the image display panel with light sources; and a controller configured to control a lighting amount of each light source. The display area includes segment areas each illuminated by one or more of the light sources. Each segment area includes subsegment areas. The controller is configured to: calculate luminance required for each subsegment area, based on an image signal for each subsegment area; temporarily set luminance values of the respective segment areas for determining the lighting amounts of the light sources based on maximum luminance among the required luminance values of the respective subsegment areas of each segment area; and reset, based on at least the maximum luminance, the luminance value of at least the segment area adjacent to the corresponding subsegment area having the required luminance of the maximum luminance.

Abstract: According to an aspect, a display device includes an image display panel; a planar light source including a light guide plate and an edge-lit light source that has light sources; and a controller. The controller sets luminance determination blocks by virtually dividing the image display panel in a light-source-arrangement-direction, identifies a luminance determination block with a highest luminance in the incidence direction, among luminance determination blocks at a same position in the light-source-arrangement-direction, identifies a luminance determination block the luminance of which is to be corrected by referring to luminance information of the light sources, and controls a light quantity of each of the light sources in such a manner that luminance of the identified luminance determination block is achieved.

Abstract: A display device includes: a display panel to display a frame image by arranging line images; and a light source. One frame period includes sub-frame periods each including a writing period and a display period. The line images are written in units of a predetermined number of lines during the writing period. The line images that are written at a time in units of the predetermined number of lines are the same image. In two continuous sub-frame periods in the one frame period, when a line image to be written during the writing period in a preceding sub-frame period differs from a line image to be written during the writing period in a subsequent sub-frame period, a start position of the writing period in the preceding sub-frame period and a start position of the writing period in the subsequent sub-frame period are shifted by one line from each other.

Abstract: The reliability of a display device with an input device is improved. A plurality of detection electrodes (input position detection electrodes) forming an electrostatic capacity between them and a common electrode of a display device to detect an input position are formed on a different substrate from substrates configuring the display device. Moreover, a polarizing plate and the substrate on which the plurality of detection electrodes are formed are adhesively fixed via, for example, an adhesive layer so that the plurality of detection electrodes are fixed so as to be separated apart from the display device. Thus, a distance between electrodes (the detection electrode and a driving electrode) for detecting an input position can be set separately from a thickness of the display device, and therefore, reduction in detection sensitivity (detection reliability) for the input position due to increase in the electrostatic capacity can be suppressed.
