Problems solved by technology

However, in this liquid crystal display device, when the 5 primary colors of RGYBC are used for displaying in 4 sub-pixels, the sub-pixels are only arranged in order to stagger the 5 primary colors of RGYBC. This configuration mode will cause effective resolution reduction or visual disadvantages

Embodiment approach 1

[0065] In this embodiment mode, a 5-primary-color display device in which sub-pixels of 4 colors are arranged for each pixel will be described.

[0066] Fig. 1 is an embodiment of a pixel constituting a 5-primary-color display device of the present invention, in a display device in which 4 color sub-pixels in R, G, B, Y and C constitute 1 pixel and the 4 sub-pixels are arranged in a strip shape , shows a conceptual diagram of the arrangement composition of the fourth or fifth sub-pixel. FIG. 1 shows a repeating unit of 2×2 pixels, and sub-pixels are arranged in stripes in one pixel.

[0067] In the display device according to the embodiment of the present invention, by using the primary colors of n colors for display, a combination of sub-pixels of n-m+1 colors in n colors is selected to form a sub-pixel arrangement pattern, so that n-m+1 sub-pixels A ratio of 1 in a pixel contains the combination. At this time, as an arrangement pattern of sub-pixels, it is appropriate to u...

Embodiment approach 2

[0091] In this embodiment mode, a four-primary-color display device in which sub-pixels of three colors are arranged for each pixel will be described.

[0092] Fig. 4 is an embodiment of a pixel constituting a 4-primary-color display device of the present invention, in a display device in which one pixel is constituted by sub-pixels of three colors in R, G, B, and Y and three sub-pixels are arranged in a strip shape , showing a conceptual diagram of sub-pixel configuration composition. In addition, in FIG. 4 , a repeating unit of 2×2 pixels is shown, and sub-pixels are arranged in a stripe shape in one pixel. Brightness of each color sub-pixel (cd / m 2 ), whose values ​​are 30 for R, 70 for G, 20 for B, and 160 for Y. Also, the average brightness of the pixel (cd / m 2 ) is 70, the color closest to this value and the second closest to this value are G and R. Furthermore, as an arrangement pattern of the sub-pixels, the third or fourth sub-pixel is arranged at the end of the p...

Embodiment approach 3

[0101] In this embodiment mode, a 5-primary-color display device in which sub-pixels of 4 colors are arranged for each pixel will be described.

[0102] Fig. 6-1 and Fig. 6-2 are an embodiment of the pixel constituting the 5-primary-color display device of the present invention, in which 1 pixel is constituted by sub-pixels of 4 colors in R, G, B, C and Y and 4 In a display device in which sub-pixels are arranged in a square shape (square shape), a conceptual diagram showing a sub-pixel arrangement configuration is shown. In addition, FIGS. 6-1 and 6-2 show a repeating unit of 2×2 pixels, and sub-pixels are arranged in a square (square shape) in one pixel. Brightness of each color sub-pixel (cd / m 2 ), whose values ​​are 30 for R, 70 for G, 20 for B, and 160 for Y. Also, the average brightness of the pixel (cd / m 2 ) is 68, the color closest to this value and the second closest to this value are G and C.

[0103]In this embodiment, Fig. 7-1 to Fig. 7-7 show that in this embo...

Abstract

An present inventive display device uses n primary colors (where n is an integer equal to or greater than four) to display an image by use of pixels including sub-pixels. Each of the pixels constituting the display device includes sub-pixel(s) of m colors (where m is an integer equal to or greater than three and is smaller than n), and every (n - m + 1)-th pixel includes sub-pixels of (n - m + 1) colors out of n colors.

Description

technical field [0001] The present invention relates to a display device and a liquid crystal display device in which a display screen is constituted by a plurality of pixels. Specifically, the present invention relates to a display that can be used in various displays such as liquid crystal televisions, PDPs (Plasma Display Panels), organic ELs (Electroluminescent: electroluminescence), and FEDs (Field Emission Displays: Field Emission Displays). multi-primary color display device. Background technique [0002] As a display device, various displays in which images are formed by pixels have been widely used as means of displaying information or video, but generally, as shown in FIG. Sub-pixels of primary colors constitute one pixel to perform color display. In recent years, in order to improve the display quality, the expansion of the color reproduction range has been studied in this color display technology. For example, in a chromaticity diagram in which the color purit...
