Description

Display panel and display device

technical field

The present invention relates to the field of display technology, and more particularly, to a display panel and a display device.

Background technique

At present, display technology has penetrated into every aspect of people's daily life, and correspondingly, more and more materials and technologies are used in display screens. As an important part of the display device, the display panel is used to realize the display function of the display device. Today, mainstream display screens mainly include liquid crystal display panels and organic light-emitting display panels (Organic Light-Emitting Diode, OLED).

Liquid crystal display panels have the advantages of thinness, low power consumption and low radiation, and are widely used in various fields. Organic light-emitting diodes, as a current-mode light-emitting device, have been increasingly used in high-performance displays. OLED display panels have self-illumination, wide viewing angles, fast response, high contrast, wide color gamut, low energy consumption, and panel Thin, rich colors, flexible display, wide operating temperature range and many other excellent features, so it is known as the next generation of "star" flat panel display technology.

The sub-pixels in the liquid crystal display panel are usually arranged in an RGB standard array, and the distance between adjacent sub-pixels is relatively small, which can achieve a high image resolution (Pixels Per Inch, PPI) design, which is relatively perfect; for organic light-emitting display panels In other words, since the sub-pixels of each color of the organic light-emitting display panel have different life spans, the sub-pixels of each color usually need to be designed with different sizes. In addition, the size of the opening of the high-precision metal mask directly determines the size of the sub-pixel. There are limitations in the preparation process of the template. Usually, the sub-pixels of each color are designed as a relatively symmetrical structure such as a circle. In addition, in order to mix the colors evenly, the sub-pixels of each color are designed as a shared algorithm and a special pixel arrangement is adopted, so it is difficult to make a standard Instead of RGB matrix arrangement, special pixel arrangement structures such as delta arrangement and 2in 1 arrangement are used, but these special pixel arrangement structures inevitably lead to a small aperture ratio, that is, the pixel definition layer is not fully utilized, wasting the display panel space, it is difficult to achieve high image resolution.

Therefore, there is an urgent need to provide a display panel and a display device capable of improving image resolution.

In all examples shown and discussed herein, any specific values should be construed as exemplary only, and not as limitations. Therefore, other instances of the exemplary embodiment may have different values.

It should be noted that like numerals and letters denote like items in the following figures, therefore, once an item is defined in one figure, it does not require further discussion in subsequent figures.

In view of the fact that the pixel arrangement structure in the related technology inevitably leads to a small aperture ratio, the pixel definition layer is not fully utilized, the space of the display panel is wasted, and it is difficult to achieve high image resolution, the inventor conducted the following research on the related technology Referring to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is a schematic plan view of a display panel provided in the related art, Fig. 2 is a schematic view of the planar structure of another display panel provided in the related art, and Fig. 3 is a plan view of the display panel provided in the related art A schematic diagram of a pixel arrangement in FIG. 1 , FIG. 2 and FIG. 3 is a common arrangement in related technologies. The three sub-pixels in Fig. 1 are a pixel repeating unit 010, the pixel repeating unit 010 has a first sub-pixel 001, a second sub-pixel 002, a third sub-pixel 003, a first sub-pixel 001, a second sub-pixel 002, a third The opening of the sub-pixel 003 is circular, and the connecting lines of the centers of the first sub-pixel 001, the second sub-pixel 002, and the third sub-pixel 003 in the same pixel repeating unit 010 form a triangle, and the two pixel repeating units in the column direction Y In 010, the arrangement positions of the first sub-pixel 001, the second sub-pixel 002, and the third sub-pixel 003 are different. It can be seen from Fig. 1 that the area K1 between adjacent sub-pixels causes a waste of space. The space is large, but no sub-pixels are set, so the pixel arrangement in Figure 1 cannot achieve high image resolution. The four sub-pixels in Fig. 2 are a pixel repeating unit 010, and a pixel repeating unit 010 has a first sub-pixel 001, a second sub-pixel 002 and two third sub-pixels 003, the first sub-pixel 001, the second The openings of the sub-pixel 002 and the third sub-pixel 003 are circular, and the area K2 between the first sub-pixel 001 and the second sub-pixel 002, and between the two third sub-pixels 003 causes a waste of space. The area K2 The space is large, but no sub-pixels are set, so the pixel arrangement in Figure 2 cannot achieve high image resolution. Figure 3 is an enlarged view of the pixel arrangement. The sub-pixels in Figure 3 take the Pentile arrangement as an example. Assume that the width of the second sub-pixel 002 in the row direction X is 10 μm, and the redundant length of the sub-pixel during deposition is 10 μm (non-opening The length of the region), the sub-pixel length is 40 μm, as shown in Figure 3, the area of the hollow area K3 surrounded by three sub-pixels is approximately 50um ² of a triangle whose base length and height are 10um; and the effective area of a single sub-pixel is about It is: 10×40=400um ² , so the effective area wasted in one pixel unit is about: 50/(400×3)=4.2%. In short, the arrangement of pixels in the related art all causes waste of space, making it difficult to achieve high resolution.

In view of this, the present invention provides a display panel and a display device for achieving high image resolution of the display panel, and specific embodiments of the display panel and the display device will be described in detail below.

In FIG. 4 , FIG. 6 and FIG. 7 , the pixel units 2000 are arranged in an array. Of course, the number of pixel units 2000 is only a schematic illustration, and is not intended to limit the number of pixel units 2000 in an actual product.

Optionally, the first sub-pixel 2001 is located in the middle of the pixel unit 2000, and the second sub-pixel 2002 and the third sub-pixel 2003 are arranged around the first sub-pixel 2001. Of course, in FIG. 4, the third sub-pixel 2003 is an L-shaped structure , At the same time, the second sub-pixel 2002 is also an L-shaped structure as an example. In this way, the L-shaped structure of the third sub-pixel 2003 has a half-enclosed space 3000, and the second sub-pixel 2002 also has the same half-enclosed space 3000. The first sub-pixel 2001 is located in the semi-enclosed space 3000, and the first sub-pixel 2001 is set in the space between the second sub-pixel 2002 and the third sub-pixel 2003. There is less waste of space for the position of the non-aperture A2, and the maximum improvement of the sub-pixel The area of the opening A1 is beneficial to improving the space utilization rate of the display panel 100 and improving the image resolution of the display panel 100 . In FIG. 6, the third sub-pixel 2003 has an L-shaped structure and the second sub-pixel 2002 is a rectangle for example. The structure in FIG. 6 is also arranged around the first sub-pixel 2001. , the first sub-pixel 2001 is located in the semi-enclosed space 3000 formed by the L-shaped structure of the third sub-pixel 2003, the first sub-pixel 2001 is set in the space between the second sub-pixel 2002 and the third sub-pixel 2003, for non-aperture The location of A2 is less wasteful, and the area of the opening A1 of the sub-pixel is maximized, which is beneficial to improving the space utilization rate of the display panel 100 and improving the image resolution of the display panel 100 . In FIG. 7 , the second subpixel 2002 has an L-shaped structure, and the third subpixel 2003 has a rectangular shape. The first subpixel 2001 is located in the semi-enclosed space 3000 formed by the L-shaped structure of the second subpixel 2002. The second subpixel 2002 The first sub-pixel 2001 is set in the space between the third sub-pixel 2003, and the space waste for the non-aperture A2 is less, and the area of the opening A1 of the sub-pixel is maximized, which is conducive to improving the space utilization rate of the display panel 100 , to improve the image resolution of the display panel 100 .

Compared with related technologies, the display panel of the present invention has at least the following beneficial effects:

In the display panel 100 of the present invention, the second sub-pixel 2002 and the third sub-pixel 2003 surround the first sub-pixel 2001, at least one of the second sub-pixel 2002 and the third sub-pixel 2003 has an L-shaped structure, and at least part of the first sub-pixel 2001 is located in the semi-enclosed space 3000 of the L-shaped structure, and the first sub-pixel 2001 is set in the space between the second sub-pixel 2002 and the third sub-pixel 2003. There is less waste of space for the position of the non-opening A2, and the maximum improvement The area of the opening A1 of the sub-pixel is beneficial to improving the space utilization rate of the display panel 100 and improving the image resolution of the display panel 100 . Even under the premise that the image resolution remains unchanged, the area of the aperture A1 of the sub-pixel can be increased, which can increase the aperture ratio of the sub-pixel. It is understandable that the service life of the light-emitting unit in the display panel is positively correlated with the luminous intensity. When the sub-pixel After the aperture ratio is increased, the total light-emitting area increases, so under the premise of the same brightness requirement, the brightness of a single sub-pixel can be reduced to meet the brightness requirement, thereby slowing down the life decay speed of the sub-pixel, improving the service life of the sub-pixel, and enhancing Display panel stability.

Waste; of course, the distance between the second sub-pixel 2002 and the opposite side of the third sub-pixel 2003 is the third distance d3, and the third distance d3 is equal in the preset difference range. In FIG. 9, the third distance d31 and the third distance d32 are at The difference is equal within the preset difference range, so as to ensure that the space between the second sub-pixel 2002 and the third sub-pixel 2003 can be utilized to the maximum extent, and no space is wasted. Also as shown in Figure 10, the distance between the opposite sides of the 0th sub-pixel 2001 and the second sub-pixel 2002 is the first distance d1, the present invention

The opposite side in refers to the position where the two sub-pixels are facing each other. The first distance d1 is equal to the preset difference range. The preset difference range here is only within the allowable range of error. The first distance d1 is relative, as shown in Figure 10 The first distance d11 and the first distance d12 are equal within the preset difference range, thus ensuring

Optionally, the first distance d1, the second distance d2, and the third distance d3 are equal within a preset difference range, or at least two of the first distance d1, the second distance d2, and the third distance d3 are not equal. In Fig. 9, the first distance d1, the second distance d2 and the third distance d3 are all unequal, and in Fig. 10 the first distance d1, the second distance d2 and the third distance d3 are equal within a preset difference range.

In the pixel arrangement design in the related art, the distance between the adjacent (opening) edges of any two sub-pixels differs greatly, the distance between some adjacent edges is small, and the distance between some adjacent edges is relatively large, then in When the minimum spacing meets the lighting conditions, the part with a larger spacing will cause a waste of space.

At this time, adjacent sub-pixels of different colors The pitches of pixels at different positions are also corresponding to the same, which can improve the accuracy of pixel evaporation. Otherwise, if adjacent sub-pixels of different colors have different pitches at different positions, and at least the minimum distance between adjacent sub-pixels of different colors must be the same as the distance between the corresponding mask plates, then the adjacent sub-pixels of different colors Parts with larger spacing between pixels will waste space, and the corresponding pixel aperture ratio will also decrease.

In the present invention, the first distance d1 is equal within the preset difference range, the second distance d2 is equal within the preset difference range, and the third distance d3 is equal within the preset difference range. The distance between adjacent positions is equal within the preset difference range, which avoids the problem of space waste, maximizes the utilization of the space area, and is conducive to improving the image resolution. The pixel aperture A1 area can increase the sub-pixel aperture ratio. It is understandable that the service life of the light-emitting unit in the display panel is positively correlated with the luminous intensity. When the sub-pixel aperture ratio increases, the total light-emitting area increases, and the same brightness Under the premise of the requirements, the brightness of a single sub-pixel can be reduced to meet the brightness requirements, thereby slowing down the life decay speed of the sub-pixel, improving the service life of the sub-pixel, and enhancing the stability of the display panel. Secondly, in the process of evaporating different sub-pixels, sub-pixels of different colors correspond to corresponding masks, and the distance between adjacent mask plates at any adjacent position is the same. The color sub-pixels have the same pitch at any adjacent position, which can improve the accuracy of pixel evaporation.
