DISPLAY DEVICE, ELECTRONIC APPARATUS, AND METHOD FOR DRIVING DISPLAY DEVICE

摘要

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.

1. A display device comprising:
an image display panel; a planar light source including a light guide plate and an edge-lit light source, the light guide plate illuminating the image display panel from a back side, the edge-lit light source including a plurality of light sources arranged facing a plane of incidence that is at least one side surface of the light guide plate; and a controller that controls luminance of each of the light sources independently, wherein the controller sets luminance determination blocks by virtually dividing the image display panel in a light-source-arrangement-direction in which the light sources are aligned and in an incidence direction that is perpendicular to the light-source-arrangement-direction, identifies a luminance determination block with a highest luminance in the incidence direction, when an image is displayed on the image display panel based on information of an input signal of the image, 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.
