DISPLAY DEVICE
A display device includes: a display panel with pixels; a dimming panel with dimming pixels; and a light source. When a pixel is controlled to be lit in white and a predetermined condition is satisfied, a blurring region is formed, and light from the light source is transmitted through the blurring region and the pixel. When a pixel is controlled to be lit up in white and the predetermined condition is not satisfied, the blurring region is not formed, the dimming pixel overlapping the pixel on a straight line along a direction in which the display panel faces the dimming panel is controlled to transmit light, and light from the light source is transmitted through the dimming pixel and the pixel. The predetermined condition is satisfied when the pixel controlled to be lit in white is at a predetermined distance or farther from an outer edge of a display area.
1 . A display device comprising:
a display panel comprising a plurality of pixels;
a dimming panel that is disposed so as to face the display panel on one surface side of the display panel and comprises a plurality of dimming pixels; and
a light source configured to emit light that travels from the dimming panel toward the display panel, wherein
in controlling the pixels in accordance with an input image signal such that at least one of the pixels is lit up in white,
when a first pixel disposed farther than a predetermined distance from a border between a display area of the display panel and a frame area of the display panel is lit up in white, a blurring process is applied such that more than one of the dimming pixels transmit light, a blurring region is formed that is a region including the dimming pixels to which the blurring process is applied, and light from the light source is transmitted through the blurring region and the first pixel and emitted to another surface side of the display panel, and
when a second pixel disposed closer to the border than the first pixel is lit up in white, the blurring process is not applied.
2 . The display device according to claim 1 , wherein the second pixel is disposed adjacent to the border.
3 . The display device according to claim 1 , wherein
the display panel receives a signal obtained by applying a first gamma correction to the input image signal, and
the dimming panel receives a signal obtained by applying a second gamma correction different from the first gamma correction to a signal obtained by applying the blurring process to the input image signal.
