Detailed Description
In view of the problems in the prior art, the invention provides a display device for improving edge color shift, wherein the same-color pixel points among the pixel sub-arrays comprising three primary colors on the display substrate are arranged in the same horizontal row and the same vertical column and are not adjacently arranged, so that the row or column with a single color does not appear on the edge of the display substrate, and the problem of color shift is effectively improved.
The embodiments of the present invention are intended to explain technical concepts of the present invention, technical problems to be solved, technical features constituting technical solutions, and technical effects to be brought about in more detail. The embodiments are explained below, but the scope of the present invention is not limited thereto. Further, the technical features of the embodiments described below may be combined with each other as long as they do not conflict with each other.
The display efficiency of a micro light emitting diode (uLED) display device can approach 70%. The virtual reality system is liberated from the constraint of a power line, and the service lives of batteries of the intelligent watch and the intelligent mobile phone are greatly prolonged. The LED display device has the advantages of low power consumption, high brightness, ultrahigh resolution and color saturation, higher response speed, longer service life and higher efficiency, and can be widely applied to various application scenes.
Referring to fig. 1 and 2, in the prior art, because the red, green, and blue pixels are sequentially arranged in rows and columns, one row or one column of the pixels may be the same color, and this may cause a single color row or a single color column on the side of the display substrate, and thus color shift is caused by lack of combination of three primary colors. As shown in fig. 1, red (R), green (G), and blue (B) pixels are arranged in sequence along the row direction, so that all red (R) pixels are present at the side row of the display substrate; as shown in fig. 2, red (R), green (G), and blue (B) pixels are arranged in the row direction of the pixel array, so that all red (R) pixels are present in the side rows of the display substrate. If the pixels are arranged in green (G), blue (B), and red (R), or in blue (B), green (G), and red (R) along rows or columns, other monochrome pixel dots may occur. Especially, the color is more obvious in large visual angle, for example, the color of red, green and blue is white when mixed, the color of red and green can be orange when the color of blue is lacking, and the color of green and blue can be turquoise when the color of red is lacking. Therefore, it is desirable to provide a solution to the color shift problem.
In summary, referring to fig. 3 to 6, the present invention provides a display device for improving edge color shift, which includes a display substrate, wherein a plurality of pixel sub-arrays 10 are disposed on the display substrate, each pixel sub-array 10 includes at least three pixels of three colors, i.e., a red pixel, a green pixel, and a blue pixel, and the same-color pixels between the pixel sub-arrays 10 are disposed non-adjacently on the same horizontal row and are disposed non-adjacently on the same vertical column. The same-color pixel points among the pixel sub-arrays 10 comprising the three primary colors on the display substrate are arranged in the same transverse row and the same longitudinal row and are not adjacently arranged, so that the rows or the rows with the single color cannot appear on the edge of the display substrate, and the problem of color cast is effectively solved.
In specific implementation, in this embodiment, the pixel sub-array 10 is taken as a unit, and the pixel sub-array 10 includes three colors of pixels, namely, a red pixel, a green pixel, and a blue pixel, so that each pixel sub-array 10 includes complete three primary colors. In order to avoid the situation that two adjacent pixels between the pixel sub-arrays 10 are same-color pixels, the same-color pixel points between each pixel sub-array 10 are set to be not adjacent to each other (that is, the last pixel point of the previous pixel sub-array is adjacent to the first pixel point of the next pixel sub-array, and the two pixel points are not same-color pixel points), and the finally formed arrangement mode is that the pixel points of each color have no adjacent same-color pixel points in the cross direction of the same longitudinal row and the same transverse row. In other words, each pixel subarray contains three pixels of red (R), green (G) and blue (B), the pixel subarray can be sequentially arranged along a row direction (taking the horizontal direction as the row direction) or a column direction (taking the direction perpendicular to the horizontal direction as the column direction), the pixels of the same color on the same row or the same column cannot be adjacent (namely, other pixels of different colors are at least spaced in the middle of the pixels of the same color), the pixels of the same color on adjacent rows or adjacent columns are staggered by one position, and the pixels of other colors are spaced in the horizontal direction or the longitudinal direction, and can only be connected in an oblique diagonal manner. The side edge of the display substrate is prevented from generating single-color rows or single-color columns, mixed color display is realized, and the rows or the columns with single color can not be generated on the edge side, so that the problem of color cast is avoided.
The invention relates to a display device which comprises a plurality of pixel points, wherein each pixel point is composed of a micro light emitting diode (uLED), and comprises a display substrate and a plurality of pixel sub-arrays 10 arranged on the display substrate, wherein the pixel sub-arrays 10 are electrically connected with a controller, and can independently regulate and control the micro light emitting diodes corresponding to red pixel points, green pixel points and blue pixel points to emit light with three colors and different wavelengths, and the full-color display effect is formed by matching with different gray scale combinations. The pixel sub-arrays 10 are micro light emitting diode combinations, and each pixel sub-array 10 is periodically arranged on the display substrate (i.e. each pixel sub-array 10 is arranged on the display substrate in turn in the same arrangement). The color mixing display is realized, the edge area of the display area does not only emit single-strip pure color light any more, and color cast caused by lack of color can be avoided.
Optionally, with continued reference to fig. 3, the pixel sub-array 10 includes three pixel points, and the three pixel points have six arrangement modes; the red pixel, the green pixel and the blue pixel in each pixel sub-array 10 are arranged in the same arrangement. The red pixel points, the green pixel points and the blue pixel points are used as a pixel sub-array 10, and no matter which arrangement mode is used by the three pixel points in the pixel sub-array 10, the arrangement modes of the pixel sub-arrays 10 are the same, so that the color light of the display substrate is uniform, and basically, no color cast exists.
In specific implementation, in this embodiment, the pixel sub-array 10 only includes three pixel points, that is, only one red pixel point, one green pixel point, and only one blue pixel point. The pixel sub-array 10 is guaranteed to contain complete three primary colors, and the number of pixel points of each color is the same, so that mixed color display is realized. In addition, the pixel points in the pixel sub-array 10 may be arranged in any one of red, green, blue, green, and blue modes, and only the condition that the same color pixel points are not adjacently arranged on the same horizontal row and are not adjacently arranged on the same longitudinal row is satisfied, so that the display substrate can be a three-primary color combination no matter the rows or the columns are, and the rows or the columns with a single color cannot appear on the edge side, thereby avoiding the color cast problem. It should be noted that, the implementation manner should satisfy that there are no adjacent same-color pixels in the pixel sub-arrays 10 and between each pixel sub-array 10 (that is, the same-color pixels are not adjacently disposed on the same horizontal row and are not adjacently disposed on the same vertical column), so as to avoid occurrence of a single-color pixel region and occurrence of color difference.
Further, referring to fig. 4 to 6, in practical applications, a problem that one of the three primary colors red pixel, the green pixel, and the blue pixel is not good in color display and needs to be compensated may occur. A scheme that the pixel sub-array 10 includes four pixel points can be selected, and the four pixel points include a pair of same-color pixel points; the same-color pixel points in the pixel sub-array 10 are not adjacently arranged on the same transverse row and are not adjacently arranged on the same longitudinal row; when any one of the same-color pixels exists, four pixel arrangement modes of the pixel sub-array 10 are provided.
In this embodiment, the pixel sub-array 10 is configured to include four pixels, wherein one pixel is added in addition to one of the red pixel, the green pixel, and the blue pixel, and the pixel is a same-color pixel of a pixel with a weaker display effect. For example, when a pair of the pixels with the same color is red, the arrangement mode is any one of red-blue-red-green, red-green-red-blue, green-red-blue-red, blue-red-green-red; when the pair of same-color pixel points are green, the arrangement mode is any one of green, red, green, blue, green and blue; when the pair of same-color pixels are blue, the arrangement mode is any one of green-blue-red-blue, red-blue-green-blue, blue-red-blue-green and blue-green-red. Specifically, the pixel sub-arrays 10 can select different pixel arrangement modes, but each pixel sub-array 10 in the same display device is the same.
This embodiment is different when the display effect is strong or weak among red pixel, green pixel, three kinds of pixels of blue pixel, set up the pixel that the display effect is weakest into two, this kind uses 4 subpixels as the arrangement mode of a pixel element (pixel subarray), can compensate to a certain extent and show weaker colour, but the condition that two kinds of single colours appear in turn also can appear in the position of row or row (for example, after red pixel appears, red pixel appears again after separating a green or blue pixel), but also has great improvement for prior art's scheme. It should be noted that, the implementation manner should satisfy that there are no adjacent same-color pixels in the pixel sub-arrays 10 and between each pixel sub-array 10 (that is, the same-color pixels are not adjacently disposed on the same horizontal row and are not adjacently disposed on the same vertical column), so as to avoid occurrence of a single-color pixel region and occurrence of color difference.
In an optional implementation manner, the pixel sub-array 10 includes five pixels, and two pairs of same-color pixels or three same-color pixels are included in the five pixels; the same-color pixels in the pixel sub-array 10 are not adjacently arranged on the same horizontal row and are not adjacently arranged on the same longitudinal row.
Specifically, the five pixel points in the pixel sub-array 10 may also be randomly arranged, but the rule that there is no adjacent same-color pixel point in the same row and the same column should also be followed, so as to avoid the occurrence of a single-color pixel region and the occurrence of color difference.
In an optional implementation manner, the pixel sub-array 10 includes six pixels, and each of the six pixels is less than or equal to three; the same-color pixels in the pixel sub-array 10 are not adjacently arranged on the same horizontal row and are not adjacently arranged on the same longitudinal row.
Specifically, the six pixel points in the pixel sub-array 10 may also be randomly arranged, but the rule that there is no adjacent same-color pixel point in the same row and the same column is also followed to avoid the occurrence of a single-color pixel region and the occurrence of color difference.
It should be noted that the number of the pixels and the arrangement of the pixels included in the pixel sub-array 10 are not limited to the above-mentioned several types, and other pixel number settings and arrangement settings capable of improving color shift are also included, but all of them are within the protection scope of the present invention.
A television set comprising a television housing and a display device as hereinbefore described for improving edge colour shift disposed within the television housing. Since the display device for improving the edge color shift is described in detail above, it is not described in detail here.
In summary, the display device and the television set for improving edge color shift provided by the invention include a display substrate, wherein a plurality of pixel sub-arrays are arranged on the display substrate, the pixel sub-arrays include pixels of three colors, namely red, green and blue, and the pixels of the same color between each pixel sub-array are not adjacently arranged on the same horizontal row and are not adjacently arranged on the same longitudinal row. According to the invention, the same-color pixel points among the pixel sub-arrays comprising the three primary colors on the display substrate are arranged on the same transverse row in a non-adjacent mode and on the same longitudinal row in a non-adjacent mode, so that rows or rows with single color cannot appear on the edge of the display substrate, and the problem of color cast is effectively improved.
