Problems solved by technology

Since the sub-pixel of the 4th color is added to every 1 pixel, the number of source drivers per pixel increases and the increased sub-pixel share occurs.

Embodiment Construction

[0071] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, a display device as a first embodiment of the present invention will be described. figure 1 It is a plan view showing the structure of the display panel of the display device according to the first embodiment of the present invention. figure 2 is an enlarged schematic diagram showing the color arrangement of sub-pixels in the display panel, image 3 is a block diagram showing the overall structure of the display panel.

[0072] First, the value of dividing the size of the display screen in the row direction by the number of pixels in the row direction is defined as the length corresponding to one pixel in the row direction, and the value of dividing the size of the display screen in the column direction by the number of pixels in the column direction is defined as It is a length corresponding to 1 pixel in the column direction. In the display panel o...

Abstract

The invention provides a display in which the luminance can be enhanced while an increase in the number of source drivers is suppressed as much as possible. When a value obtained by dividing the size of a display screen in the column direction by the number of pixels in the column direction is the length corresponding to one pixel in the column direction, one period of color arrangement in the column direction is the length corresponding to two pixels and one period of that color arrangement consists of two subpixel groups having mutually equal subpixel arrangements arranged along one column while including subpixels (1) of three primary colors of light, i.e. red (R), green (G) and blue (B), and one extra subpixel (1A). Each subpixel (1, 1A) is connected respectively with a scanning line (2) extending along the column direction and a signal line (3) extending along the row column direction.

Description

technical field [0001] The present invention relates to a display device including a color display panel such as a liquid crystal display or an organic electroluminescence (EL: Electro Luminescent) display. Background technique [0002] This type of display device is provided with a display panel that forms a color image using a plurality of pixels that are generally regularly arranged, and is widely used as display screens of personal computers, mobile phones, portable information terminals, and thin televisions. Here, in order to realize a color display, one pixel is generally constituted by sub-pixels of three primary colors of light: red (R), green (G), and blue (B). A sub-pixel is a display unit that can be independently driven and controlled. [0003] In addition, the colors of the sub-pixels included in one pixel are not particularly limited to the three primary colors of light, as long as they can realize color display. For example, three colors of cyan (C), yellow...
