Description

FIELD OF INVENTION

The present disclosure relates to a technical field of displays, and more particularly to a pixel array.

BACKGROUND OF INVENTION

In-plane color shifts are an important parameter for evaluating panel quality. In-plane color shifts are an important indicator of display color uniformity of different regions of gray scale screens. Therefore, how to improve color uniformity and make in-plane color shifts as small as possible is an inevitable problem for various panel manufacturers.

Currently, to improve an in-plane color shift, an industry primarily uses color demura (color compensation) technology. The technology is similar to demura (luminance compensation) technology and is different in that the demura technology aims at luminance non-uniformity, and the color demura aims at in-plane color uniformity. The color demura technology uses an integrated algorithm in an integrated circuit (IC) to adjust a plurality of gray scales of a plurality of different regions, thereby improving the color uniformity. Although the aforementioned method may improve the in-plane color shift, an additional IC cost is needed.

In order to ensure display consistency of a gray scale screen of a display panel, white balance correction needs to be performed on the display panel. However, after the white balance correction is performed on the display panel, an in-plane color shift is worsened.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The description of each embodiment below refers to respective accompanying drawing(s), to illustrate exemplarily specific embodiments of the present disclosure that may be practiced. Directional terms mentioned in the present disclosure, such as “upper”, “lower”, “front”, “back”, “left”, “right”, “inner”, “outer”, “side”, etc., are only directions by referring to the accompanying drawings, and thus the used directional terms are used to describe and understand the present disclosure, but the present disclosure is not limited thereto. In the drawings, structurally similar units are labeled by the same reference numerals.

The present disclosure is directed to a technical problem that, color non-uniformity of a display panel under a gray scale screen causes the display panel to generate an in-plane color shift. The present embodiment can solve the deficiency.

The present disclosure provides a pixel array to solve the aforementioned problem.

Referring to FIG. 1 or 2, the present disclosure provides a pixel array 10. The pixel array 10 includes a plurality of pixel units. Each pixel unit correspondingly includes a plurality of sub-pixels having a plurality of color types, and the sub-pixels having the color types includes at least one blue sub-pixel B, and a plurality of sub-pixels having other color types of the color types.

In the pixel array 10, a proportion of the at least one blue sub-pixel B is larger than a proportion correspondingly of at least one sub-pixel of the sub-pixels correspondingly having each color type of the other color types of the color types.

When a white balance correction process is performed, a plurality of gray scale values correspondingly of a plurality of blue sub-pixels B drop, causing color uniformity of a display device to be worsened. In the present embodiment, in the pixel array 10, the proportion of the at least one blue sub-pixel B is increased, and is larger than the proportion correspondingly of at least one sub-pixel of the sub-pixels correspondingly having each color type of the other color types of the color types. This causes that when the white balance correction process is performed, even if a plurality of gray scale values correspondingly of the blue sub-pixels B drop, because the proportion of the at least one blue sub-pixel B is larger, color uniformity of the pixel array 10 is improved, and a display effect of a display device is enhanced.

Specifically, as shown in Tables 1 and 2, each degree of a plurality of degrees correspondingly of a plurality of in-plane color shifts is represented by Δx and Δy, wherein Δx represents a difference between a maximum value and a minimum value of a plurality of x color coordinates correspondingly of nine different regions in a plane, and Δy represents a difference between a maximum value and a minimum value of a plurality of y color coordinates. Table 1 represents a data table when white balance correction is performed. Table 2 represents a data table when the white balance correction is not performed. As can be seen from the data tables, when the white balance correction is performed on the pixel array, both a pair of values correspondingly of Δx and Δy are increased, i.e., the in-plane color shift is worsened.

Taking red, green and blue sub-pixels correspondingly having three color types as an example, based on an analysis of an effect of the white balance correction on display of the panel, a gray scale value corresponding to the blue sub-pixel B drop a lot. Taking a forty eighth level as an example, when the white balance correction is performed, a gray scale value of the blue sub-pixel B is reduced from the forty eighth level to a thirty sixth level, and a plurality of gray scale values correspondingly of the other sub-pixels are not changed. Hence, in-plane color uniformity is worsened.

As shown in Table 3, with the increase of the gray scale value of the blue sub-pixel B, a value of Δy is decreased, i.e., the in-plane color shift is improved.

	TABLE 3
	R	G	B	Δy

Therefore, as long as the gray scale value of the blue sub-pixel B is increased, the in-plane color shift is improved. The present embodiment improves the in-plane color shift by increasing the proportion of the at least one blue sub-pixel B in the pixel array 10.

Take the red, green and blue sub-pixels correspondingly having the three color types as an example and compare two cases. Under a first case, all of a plurality of proportions of the sub-pixels correspondingly having the three color types are one-third. Under a second case, a proportion of the blue sub-pixel B is one-half and a proportion correspondingly of one sub-pixel of the sub-pixels correspondingly having each color type of the other color types is one-fourth. When the white balance correction is performed, under the first case, a gray scale value of the blue sub-pixel B is reduced to thirty six, and a gray scale value correspondingly of one sub-pixel of the sub-pixels correspondingly having each color type of the other color types are all forty eight. Under the second case, a gray scale value of the blue sub-pixel B is fifty five, and a gray scale value correspondingly of the one sub-pixel of the sub-pixels correspondingly having each color type of the other color types is forty seven. A result is that when the proportion of the blue sub-pixel B is one-half, an in-plane color shift is improved significantly. Therefore, in the present embodiment, the gray scale values correspondingly of the blue sub-pixels B are increased by making the proportion of the at least one blue sub-pixel B to be larger than the proportion correspondingly of the at least one sub-pixel of the sub-pixels correspondingly having each color type of the other color types of the color types, to enhance a display effect of the display device.

Further, in the present embodiment, in the pixel array 10, the pixel units include at least one first pixel unit 101, and in each first pixel unit 101 of the at least one first pixel unit 101, a proportion of the at least one blue sub-pixel B is larger than a proportion correspondingly of the at least one sub-pixel of the sub-pixels correspondingly having each color type of the other color types of the color types.

In each second pixel unit of the at least one second pixel unit, a proportion correspondingly of at least one sub-pixel of the sub-pixels correspondingly having each color type of the color types is same.

In each second pixel unit of the at least one second pixel unit, a number correspondingly of the at least one sub-pixel of the sub-pixels correspondingly having each color type of the color types is same, and an area of a single pixel of the at least one sub-pixel of the sub-pixels correspondingly having each color type of the color types is same. The pixel array 10 include the at least one first pixel unit 101 and the at least one second pixel unit 102 at the same time.

In the pixel array 10, a proportion of the at least one red sub-pixel R may be equal to a proportion of the at least one green sub-pixel G. The proportion of the at least one blue sub-pixel B in the pixel array 10 is larger than one-third.
