Embodiment 1
[0036]
[0037] in figure 1 , The display information input part 1 inputs color display information. Display control part 2 control figure 1 In order to perform sub-pixel display, each element of the display device 3 is displayed based on the display image stored in the display image storage unit 11 (VRAM etc.).
[0038] In the display device 3, three light-emitting units that emit light of the three primary colors of RGB are arranged in a certain order to form a pixel, the pixels are arranged in the first direction to form a row, and the row is along the first direction perpendicular to the first direction. Set multiple in 2 directions to form a display screen. Specifically, it is composed of a color LCD, a color plasma display, an organic EL display, etc., and a driver that drives each of these light-emitting units.
[0039] The display control part 2 stores the color display information input from the display information input part 1 into the color image storage part 4. The ...
Embodiment 2
[0087] In this embodiment, as image 3 As shown, compared with Example 1, a chrominance distribution unit 12 is additionally provided between the luminance and chrominance separation unit 5 and the luminance and chrominance synthesis unit 8. And, in its processing flow, such as Figure 4 As shown, between step 3 and step 4, chromaticity allocation processing (step 9) is added. The order of step 3 and step 9 can be the order shown in the figure, or step 9 can be performed before step 3.
[0088] image 3 The chromaticity distribution unit 12 inputs the chromaticity data Cb(x, y) and Cr(x, y) separated by the luminance and chromaticity separation unit 5, and performs the process of suppressing bleeding by the following formula to obtain the distributed The chrominance values Cb'(x, y) and Cr'(x, y) are transmitted to the luminance / chrominance synthesis unit 8.

Abstract
Display of color sub-pixels is performed by using a display device with three light-emitting units arranged in a matrix to emit RGB three primary colors respectively. Separate pixel-accurate color information into pixel-accurate luma data and pixel-accurate chrominance data. Based on the pixel-accurate brightness data, sub-pixel-accurate brightness data is generated. Combining the luminance data with sub-pixel precision and the chrominance data with pixel precision, the color information with sub-pixel precision is obtained.
Description
Technical field [0001] The present invention relates to the display technology of a display device incorporating RGB three primary color light-emitting units, and particularly relates to color display with sub-pixel accuracy (in this specification, grayscale display and general color display are collectively referred to as "color display"). Background technique [0002] Display devices using various display devices have been used so far. Among these display devices, for example, color LCD, color plasma display, organic EL (electroluminescent, electroluminescence) display, etc., three light-emitting units emitting RGB three primary colors are arranged in a certain order, as a pixel, The pixels are arranged side by side in the first direction to form one row, and the rows are arranged in a plurality of rows in the second direction perpendicular to the first direction to form a display screen. [0003] For example, like display devices mounted on mobile phones ...
