Embodiment approach 1

[0063] figure 1 The liquid crystal display device 100 of this embodiment is shown. Such as figure 1 As shown, the liquid crystal display device 100 includes a resolution conversion device 10 and a four-primary-color liquid crystal display module 20 , and is a multi-primary-color display device that uses four primary colors for display.

[0064] Although not shown, the four-primary-color liquid crystal display module 20 includes a liquid crystal display panel, a gate driver, a source driver, a timing controller, a backlight (illumination device), and the like. The liquid crystal display panel has a plurality of pixels arranged in a matrix including rows and columns.

[0065] The specific pixel structure (sub-pixel configuration) of the LCD panel is in figure 2 Indicated. Such as figure 2 As shown, each of the plurality of pixels P includes four sub-pixels displaying mutually different colors. Specifically, the four sub-pixels are a red sub-pixel R that displays red, a g...

Abstract

Disclosed is a display device that is provided with a plurality of pixels disposed in a matrix, wherein the plurality of pixels are each formed from four types or five types of subpixels that display mutually different colors. Within each pixel, a first subpixel, which displays the color with the highest intensity, and a second subpixel, which displays the color with the second highest intensity, is arranged in a nonadjacent manner. The four types or five types of subpixels include a plurality of display units that each display a specified color and that are each formed by one or more continuous subpixels. In cases in which the resolution of an input image is higher than the display resolution defined by the total number of pixels, the display device displays each of the plurality of display units as a virtual pixel, thereby providing a multi-primary color display device in which a decrease in display definition is suppressed even if the resolution of the input image is higher than the resolution of the display device.

Description

technical field [0001] The present invention relates to a display device, especially a multi-primary color display device that uses 4 or 5 primary colors for display. Background technique [0002] When the resolution of the image data input to the display device is different from that of the display device, the input image is displayed enlarged or reduced. That is, when the number of pixels of the input image is different from the total number of pixels of the display device, the number of pixels of the input image is displayed on the display device with a number of pixels different from the number of pixels of the input image. [0003] As a method for enlarging or reducing an input image, there are known bilinear method (bi-linear method) or bicubic method (bicubic method). In these methods, for pixels that do not exist in the input image, the values ​​of surrounding pixels are averaged or weighted to perform interpolation, or operations such as filter processing are used ...
