On the other hand, if it is desired to smoothly display the outermost peripheral portion of the display area by covering the non-display area with a black matrix or the like, the pixels located at the boundary between the display area and the non-display area are covered by each sub-pixel constituting one pixel. Partially covered areas are different, and there may be a problem that the desired color cannot be expressed

Embodiment approach

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same reference numerals are assigned to the same or corresponding parts, and description thereof will not be repeated. In addition, in order to facilitate understanding and description, in the drawings referred to below, the configuration is simplified or schematically shown, or some constituent members are omitted. In addition, the dimensional ratio between the constituent members shown in each drawing does not necessarily represent an actual dimensional ratio.

[0032] In the following description, a case where the display device is a liquid crystal display will be described. However, the display device of the present invention is not limited to a liquid crystal display, and may be an organic EL display, a plasma display, or the like.

[0033] The display device is, for example, a smartphone. However, the display device is not limited t...

no. 1 Embodiment approach

[0035] figure 1 It is a figure showing the appearance shape of the display device 100 of 1st Embodiment. The display device 100 according to the first embodiment has a non-rectangular shape, and its corners are not right angles, but R-shaped with smooth curves. Similarly, the image display area 11 is also a non-rectangular shape with R-shaped corners. The outside of the display area 11 is a non-display area 12 .

[0036] figure 2 It is an enlarged view of the upper left corner of the display area 11 of the display device 100 . A plurality of pixels 2 are arranged in a matrix in the display device 100 . Each pixel 2 has a rectangular shape. exist figure 2 In , the lower side of the boundary line 13 of the display area is the display area 11 , and the upper side is the non-display area 12 . Rectangular pixels 2 are arranged not only in the display area 11 but also in the non-display area 12 .

[0037] Such as image 3 As shown, one pixel 2 is composed of three sub-pi...

no. 2 Embodiment approach

[0055] In the first embodiment, the case where the non-display area 12 is black has been described. In the second embodiment, a case where the non-display area 12 is white will be described. In this case, a pixel in which all sub-pixels are located in the non-display area 12 may be covered with a white film, or the pixel may be displayed in white.

[0056] In the case where the non-display area 12 is white, if the luminance of a pixel in which all sub-pixels are located in the non-display area 12 is set as T1, and the luminance of a pixel in which all sub-pixels are located in the display area 11 is set as T2, the boundary pixel The brightness of is set to T3, then the relationship of the following formula (4) is established. Here, the luminance value T2 of a pixel whose all sub-pixels are located in the display area 11 refers to the luminance value of a pixel in which all sub-pixels are located in the display area 11 among pixels adjacent to the target boundary pixel.

Abstract

The present invention suppresses the generation of staircase-shaped wobbled display in a display device having a display area of non-rectangular shape in which rectangular pixels are arranged. A display device having a non-rectangular display area is provided with a luminance value adjustment unit where rectangular pixels constituted from a plurality of sub-pixels that each correspond to a plurality of colors are arranged in a plural number in a display area and a non-display area, and the luminance value of boundary pixels partially included both in the display area and in the non-display area is adjusted at image display time so as to be intermediate between the luminance value of pixels that have all the sub-pixels in the non-display area and the luminance value of pixels that are adjacent to the boundary pixels and have all the sub-pixels in the display area.

Description

technical field [0001] The present invention relates to display devices. Background technique [0002] In recent years, development of a display device having a non-rectangular display area has been progressing. When all the pixels are rectangular, if the display control is performed in units of pixels, there may be a stepwise blurring display at the outermost peripheral portion of the display area. On the other hand, if it is desired to smoothly display the outermost peripheral portion of the display area by covering the non-display area with a black matrix or the like, the pixels located at the boundary between the display area and the non-display area are covered by each sub-pixel constituting one pixel. Partially covered areas are different, and there is a problem that desired colors cannot be expressed. [0003] In order to cope with such a problem, Patent Document 1 discloses a technique of realizing a non-rectangular display area with a smooth outer peripheral conto...
