Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display panel and an electronic device. Background Art

[0002] The pixel arrangement in the current conventional display panel is as follows Figure 1 As shown, the black outer frame represents the edge of the display panel. Pixels of different colors are typically arranged with varying lengths and widths due to differences in luminous efficiency and luminescent materials. They are arranged so that the long axis of each pixel is parallel to the vertical direction of the display surface of the display panel. Pixels marked with R are red, pixels marked with B are blue, and pixels marked with G are green. In actual arrangement, the number of green pixels represents the actual resolution of the display panel. Red and blue pixels use a borrowed color scheme, so that two adjacent green pixels share a group of red and blue pixels, forming two white pixels.

[0003] But using Figure 1 The display panel implemented in this manner has a problem of a large difference between the width M of a single horizontal line and the width N of a single vertical line during actual display, which in turn causes the display panel to easily cause uneven display effects when presenting the display image. In addition, there is pixel redundancy for the red and blue pixels at the edge of the display surface, which requires additional algorithms to be compensated, which is not conducive to simplifying the drive control of the display panel.

[0006] In some embodiments, a first sub-pixel row and a second sub-pixel row form a pixel row, and there is an overlapping part between the projections of the first sub-pixel and the second sub-pixel in each pixel row in the first direction and the second direction, wherein the second direction is a direction perpendicular to the first direction in the display panel.

[0007] In some embodiments, the width of a single horizontal line of the display panel is the distance between an edge of the third sub-pixel and an edge of the second sub-pixel adjacent to each other in the first direction in the pixel row.

[0008] In some embodiments, the width of a single vertical line of the display panel is the distance between edges of two adjacent third sub-pixels in the pixel row in the second direction.

[0010] In some embodiments, the first angle is 45 degrees.

[0011] In some embodiments, the first sub-pixel is a blue pixel, the second sub-pixel is a red pixel, and the third sub-pixel is a green pixel.

[0012] In some embodiments, a pixel number ratio between the red pixels, the blue pixels, and the green pixels is 1:1:2.

[0027] This description may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," each of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0028] The pixel arrangement in the current conventional display panel is as follows Figure 1 As shown, the black outer frame represents the edge of the display panel. Pixels of different colors are typically arranged with varying lengths and widths due to differences in luminous efficiency and luminescent materials. They are arranged so that the long axis of each pixel is parallel to the vertical direction of the display surface of the display panel. Pixels marked with R are red, pixels marked with B are blue, and pixels marked with G are green. In actual arrangement, the number of green pixels represents the actual resolution of the display panel. Red and blue pixels use a borrowed color scheme, so that two adjacent green pixels share a group of red and blue pixels, forming two white pixels.

[0029] But using Figure 1 The display panel implemented by the method has a problem of a large difference between the width M of a single horizontal line and the width N of a single vertical line when actually displaying, which leads to uneven display effect when the display panel presents the display picture. Figure 1 As shown, the width of a single horizontal line, M, refers to the distance between the edges of red pixels in each row, and the width of a single vertical line, N, refers to the distance between the edges of green and red pixels in each column. Furthermore, there is pixel redundancy for red and blue pixels at the edges of the display surface, requiring additional algorithms to compensate, which hinders the simplification of display panel drive control.

[0030] In order to solve the above problems, the first embodiment of the present disclosure provides a display panel, which is mainly an organic light-emitting diode (OLED) display panel. The display panel has a pixel arrangement different from that of a conventional display panel. Specifically, Figure 2 shown. Figure 2 The diagram shows the arrangement of the pixel units of the display panel in this embodiment. Figure 2It can be seen that the multiple pixel units in this embodiment are arranged in an array according to a certain rule, wherein the pixel units mainly include a first sub-pixel, a second sub-pixel and a third sub-pixel, which correspond to pixel units showing different colors respectively. When arranging, the first sub-pixel and the third sub-pixel are alternately arranged in sequence to form a first sub-pixel row, and the third sub-pixel and the second sub-pixel are alternately arranged in sequence to form a second sub-pixel row. The pixel unit arrangement of the display panel is based on the alternating arrangement of the first sub-pixel row and the second sub-pixel row in the first direction, and the long axis direction of the first sub-pixel and the second sub-pixel when arranged has a first angle α with the first direction, so that the pixel unit as a whole is arranged at a certain angle to the right (or left). Specifically, the first direction in this embodiment mainly refers to the extension direction of the data line in the display panel, which is generally the vertical direction of the display panel, corresponding to Figure 2 In the figure, X represents the direction, and Y represents the long axis direction of the first sub-pixel and the second sub-pixel. In this embodiment, the first sub-pixel corresponds to the blue pixel (corresponding to Figure 2 The sub-pixel marked with the letter B in the middle), the second sub-pixel corresponds to the red pixel (corresponding to Figure 2 The sub-pixel marked with the letter R in the middle), the third sub-pixel corresponds to the green pixel (corresponding to Figure 2 The sub-pixel marked with the letter G in the middle), since the size of green pixels is generally smaller, the actual setting can refer to the setting direction of red pixels and blue pixels. It should be noted that Figure 2 The X direction shown in the figure is the fixed vertical direction, and the Y direction is the opposite direction after rotating clockwise by a certain angle based on the X direction. In practice, the Y direction can also be the direction rotated counterclockwise by a certain angle based on the X direction. The specific setting can be based on actual conditions, as long as the long axes of the first and second sub-pixels are at a certain angle to the vertical direction. In addition, the first and second sub-pixel rows mentioned in this embodiment do not mean that their corresponding driving TFTs are located in the same row or not. It is only used to indicate that the openings of the pixels are located in the same row.

[0031] In this embodiment, all pixel units contained in a first sub-pixel row and a second sub-pixel row adjacent to each other form a pixel row, and the display panel is formed based on multiple pixel rows arranged along the first direction. It should be noted that each first sub-pixel row and each second sub-pixel row belongs to only one pixel row, and the projections of the first sub-pixel and the second sub-pixel in any pixel row in the first direction and the second direction have overlapping parts. Combined with the setting of the long axis direction, the arrangement of the pixel units in the display panel formed in this embodiment is significantly different from the arrangement in the prior art, avoiding the problem of redundant setting of RB pixels at the edge of the display panel. It should be noted that the second direction is the direction perpendicular to the first direction in the display panel, such as Figure 2The Z direction is shown in FIG. 1 , which may actually be the direction in which the gate lines of the TFTs in the display panel extend.

[0032] In actual implementation, the first angle α can be set between 30 degrees and 60 degrees, and can be preferably set to 45 degrees to ensure that there is enough space for pixel units to be arranged at the edge of the display panel. Generally speaking, one adjacent red pixel, one blue pixel and one green pixel form a white pixel (corresponding to Figure 1 and Figure 2 In the actual display, different colors are mixed by adjusting the brightness of the RGB pixels in the white point pixel, and the color is presented as the most basic display unit in the display panel. Based on the borrowed color scheme, each group of R pixels and G pixels can form two white point pixels with the two G pixels arranged above and below them respectively. Figure 1 In conventional pixel arrangements, there's no space above (or below) the R and B pixels at the edge of the display panel for G pixels, so the brightness of the R and B pixels at the edge is only borrowed once, resulting in pixel redundancy. However, in this embodiment, by varying the pixel unit arrangement angle, space is created for G pixels at the edge of the display panel, achieving a 1:1:2 ratio of R pixels to B pixels to G pixels. Even R and B pixels at the edge can form two independent white pixels with two G pixels, thereby avoiding pixel redundancy. This also eliminates the need for additional algorithms for redundant pixels, reducing the complexity of the display panel drive control method.

[0033] Specifically, the display panel includes a first side, a second side, a third side and a fourth side whose ends are sequentially connected, which correspond to the four sides of the display panel respectively, wherein the first side and the third side are arranged opposite to each other, and the second side and the fourth side are arranged opposite to each other. Figure 2 For example, the upper side of the display panel can be set as the first side, the left side as the second side, the lower side as the third side, and the right side as the fourth side. Combined with the arrangement of the pixel units disclosed in this embodiment, for the display panel, the pixel units close to the first side and the third side are the first sub-pixels and the third sub-pixels arranged alternately, corresponding to Figure 2 The pixels near the upper and left sides are alternating blue pixels and green pixels, and the pixel units near the second and fourth sides are alternating third and second sub-pixels, corresponding to Figure 2 The pixels near the lower side and the right side are alternating green pixels and red pixels, so that the green pixels are fully arranged at the edge of the display panel to avoid the red and blue pixel redundancy.

[0034] The pixel unit in this embodiment is divided into a plurality of pixel groups, each of which includes one red pixel, one blue pixel, and two green pixels. Figure 3 The diagram shows the arrangement of pixels in a pixel group. Taking the first angle α of 45 degrees as an example, the red pixels and blue pixels in each pixel group are arranged in the vertical direction along the Y direction, and the distance between the two can be set in combination with the display panel size requirements and the conventional manufacturing specifications of the display panel; the two green pixels in the pixel group are arranged in the Y direction, and the vertical distance between each green pixel and the center point connection line of the red pixel and the blue pixel is the same, that is, the two green pixels are respectively arranged on both sides of the center point connection line OO', and the vertical distances h1 and h2 between the center point of the green pixel and the center point connection line OO' are the same, thereby ensuring that the two white point pixels formed by each pixel group are the same size, forming a better display effect.

[0035] Furthermore, during the lighting test of the display panel, it may be necessary to light up only any row or column of pixels in the display panel to observe its display effect. The row or column of pixels that are lit here should be a pixel row or pixel column formed by white dot pixels composed of blue pixels, red pixels and green pixels. The width of a single row of pixels is called the single horizontal line width of the display panel, and the width of a single column of pixels is called the single vertical line width of the display panel. Generally, the difference between the single horizontal line width and the single vertical line width can be used to represent the uniformity of the display panel. For the single horizontal line width and the single vertical line width of the display panel in the prior art, the single horizontal line width is too wide, while the single vertical line width is too narrow, and the uniformity of the display panel is poor. Figure 2 The single horizontal line width and single vertical line width of the display panel in this embodiment are also shown. Specifically, the single horizontal line width M of the display panel in this embodiment is the distance between the edge of the third sub-pixel and the edge of the second sub-pixel adjacent in the first direction within a single pixel row, and the single vertical line width is the distance between two adjacent edges of the third sub-pixel in the second direction within a single pixel row. Due to the adjustment of the pixel arrangement direction in this embodiment, the single horizontal line width is reduced compared to the single horizontal line width in the conventional solution, while the single vertical line width is increased compared to the single vertical line width in the conventional solution. This reduces the difference between the single horizontal line width and the single vertical line width, resulting in a more uniform display effect on the display panel.

[0036] It should be noted that when the display panel is actually prepared, the specific values ​​of the single horizontal line width M and the single vertical line width N of the display panel will change according to the actual size of the display panel, the number of pixels and the value of the first angle. For example, for a 5cm*5cm display panel, 1000 white dot pixels need to be set in both the single row and the single column. In theory, the optimal values ​​of the single horizontal line width M and the single vertical line width N are 50um (5 / 1000*10000). At this time, the most uniform display effect can be guaranteed. Therefore, the pixel units can be arranged in combination with the theoretical optimal values ​​of the single horizontal line width M and the single vertical line width N, so that the actual values ​​of the final horizontal line width M and the single vertical line width N are as close to the theoretical values ​​as possible to achieve a better display effect.

[0037] This embodiment adjusts the arrangement of the individual pixel units in the display panel so that a first angle exists between the long axis directions of the first and second sub-pixels and the first direction. This creates space for a third sub-pixel at the edge of the display panel, fully utilizing the pixels at the edge and avoiding pixel redundancy. This also reduces the difference between the widths of a single horizontal line and a single vertical line in the display panel, resulting in a more uniform display. Furthermore, during the actual manufacture of the display panel in this embodiment, only the orientation of the individual pixel units needs to be adjusted, and the number of pixel units needs to be adjusted based on the actual size and resolution of the display panel. No adjustments are required to the manufacturing materials, manufacturing process, pixel size, or other parameters. While achieving a better display quality for the display panel, no additional manufacturing process or other parameter adjustments are required.

[0038] The second embodiment of the present disclosure provides an electronic device, which can be any device with a display function, such as a television, a computer monitor, a mobile phone, a watch, a speaker, a camera, etc. The electronic device of this embodiment includes at least the display panel provided by the first embodiment of the present disclosure, so that the display screen of the electronic device can achieve a better display effect, and when driving each pixel in the display panel to light up, there is no need to set an additional compensation algorithm, which simplifies the pixel drive control method. At the same time, in addition to the display panel, other hardware structures or software programs included in the electronic device can be set according to the actual functional requirements of the electronic device, and this embodiment does not impose any detailed restrictions.

[0039] The above describes in detail multiple embodiments of the present disclosure, but the present disclosure is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications to the embodiments based on the concepts of the present disclosure, and these variations and modifications should all fall within the scope of protection claimed by the present disclosure.
