Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A display substrate, a display screen, and an electronic apparatus according to an embodiment of the present invention are described below with reference to the drawings.
Fig. 3 is a schematic structural diagram of a display substrate according to an embodiment of the present invention.
As shown in fig. 3, the display substrate 10 (not shown) may include a substrate 11 (not shown), a display array 12 disposed on the substrate 11, and a BM region 13.
The display array 12 is composed of a plurality of display pixels 121 and compensation pixels 122, and is in an R-corner shape.
The display pixel 121 at the edge of the display array is adjacent to one side of the compensation pixel 122, and the other side of the compensation pixel 122 is adjacent to the BM region 13.
Each display pixel 121 at the edge of the display array corresponds to two compensation pixels 122.
When the color of the display pixel 121 located at the edge of the display array is the first color, the colors of the two corresponding compensation pixels 122 are the second color and the third color, respectively. The first color is one of the three primary colors, and the second color and the third color are the other two of the three primary colors.
For example, if the color of the display pixel 121 located at the edge of the display array is blue, the colors of the two corresponding compensation pixels 122 are red and green, respectively.
The display pixels 121 located at the edge of the display array and the two corresponding compensation pixels 122 are in parallel connection, and the output voltages are the same.
In one embodiment of the present invention, the sum of the display areas of the two compensation pixels 122 may be less than or equal to the display area of one display pixel 121.
The following is described as an example.
As shown in fig. 3, assuming that the area of the blue display pixel located at the leftmost side of the first row is 1, the corresponding two compensation pixels are respectively red and green, and the height and width of the two compensation pixels are half of the blue display pixel, so the areas of the two compensation pixels are 1/4. Since the real area of the pixel is very small, it is difficult for the naked eye to see the size of the pixel, so that the color of the blue display pixel and the two compensation pixels looks like blending together and approaches to white by using the characteristic of three primary colors (red, green and blue are combined into white). Similarly, the leftmost blue display pixel of the other rows is also balanced for blue by the red and green compensation pixels. Finally, the color shift problem of the pixel with weakened R angle is realized.
It should be understood that the area of the compensation pixel is not limited to 1/4 which is the area of the display pixel described in the above example, but may be the sum of the areas of two compensation pixels equal to the area of the display pixel as shown in fig. 4. The red compensation pixel is located above the green compensation pixel, which is also described as an example, and other combinations are also possible, for example, the red compensation pixel is located below the green compensation pixel, which is not limited in this example.
According to the display substrate provided by the embodiment of the invention, the color cast problem of the R angle is solved by arranging the two corresponding compensation pixels aiming at the display pixels positioned at the edge of the display array, and the display substrate is simple in process and low in cost.
In order to implement the above embodiments, the present invention further provides a display screen, which includes the display substrate of the previous embodiment.
The display screen may be a display screen of an electronic device such as a mobile terminal and a tablet computer.
