Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, it is to be understood that the terms "center", "lateral", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner" and "outer" etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention. Further, when an element is referred to as being "formed on" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.
The inventor researches and discovers that the distance between the pixel units is increased due to the non-uniform deformation of the flexible display screen in the stretching state, and the distance is a main reason for the local display blurring or the display effect reduction of the flexible display screen in the stretching state. Further, after a great deal of stretching tests and analysis are performed on the stretchable flexible display screen, the inventor finds that the deformation amount of the region of the flexible display screen closer to the middle part is relatively larger during stretching, which causes the pixel density (Pixels Per inc, PPI) of the region of the flexible display screen with larger deformation amount to be reduced more, thereby affecting the display effect of the region, and causing the display effect of the region to be blurred, distorted and the like.
In order to solve the above problems, the inventors innovatively provide a flexible display panel and an electronic device, which can effectively solve the problem of display effect degradation such as display blurring and display image distortion caused after the flexible display panel is stretched by differentially setting the number of pixel units in different pixel island regions of the flexible display panel. Alternative embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1, after the conventional flexible display panel is stretched in the transverse direction, the increase of the distance between the pixel units in the middle area is greater than the increase of the distance between the pixel units in the two side areas. When the stretched flexible display panel is used for displaying, the problems of low definition, fuzzy display pictures, distortion of display images and the like can occur in the middle area of the flexible display panel. Similarly, referring to fig. 2 and fig. 3 in combination, the problem of reduced display effect in the middle area also occurs after the conventional flexible display panel is stretched in the longitudinal direction and the transverse direction.
In order to solve the above problem, embodiments of the present invention provide a flexible display panel and an electronic device, in which the number of pixel units in different pixel island regions is designed to be decreased along a set direction, so that a problem of a decrease in display effect of a middle region of the flexible display panel due to stretching can be solved. In the present embodiment, the set direction may be understood as a stretchable direction of the flexible display panel. Further, the set direction may be a direction extending from a central region located in the substrate toward an edge of the substrate.
In practical applications, the embodiment of the invention exemplarily provides three number designs of pixel units considering that different use requirements of the flexible display panel may correspond to different stretching directions. It should be understood that the following design is exemplary only and not limiting.
A first design may be performed for a flexible display panel with a requirement of lateral stretching, as shown in fig. 4, the flexible display panel 100 may include a substrate 1, the substrate 1 may include a plurality of pixel island regions 2, and each pixel island region 2 may include at least two pixel units 21. In this embodiment, each pixel unit 21 may include 3 sub-pixels (red, green, and blue), and each pixel unit 21 may also include 4 sub-pixels (one red, two green, and one blue), which is not limited herein.
Further, the number of pixel cells 21 of adjacent pixel island regions 2 arranged in a direction extending from an axis located at the center of the substrate 1, which may be the longitudinal axis L1 of the substrate 1, toward the edge of the substrate 1 is sequentially decreased. Here, a direction extending from an axis located at the center of the substrate 1 toward the edge of the substrate 1 may be understood as a set direction.
By such a design, when the flexible display panel 100 is stretched along the arrow direction in fig. 4, as the number of the pixel units 21 in the pixel island region 2 closer to the middle of the substrate 1 is larger, and correspondingly, the number of the pixel units 21 in the pixel island region 2 corresponding to the region with the larger deformation amount is also larger, the pixel units 21 can be uniformly distributed as much as possible after the substrate 1 is subjected to stretching deformation, so that the distribution of the pixel units 21 of the flexible display panel 100 after being transversely stretched tends to be uniform as much as possible, and the problems of unclear display screen, display image distortion and other display effects caused by the large PPI reduction in the middle of the substrate 1 are avoided.
In some embodiments, the number of pixel units 21 in the adjacent pixel island region 2 arranged along the set direction may sequentially decrease linearly or non-linearly in the set direction. In this embodiment, taking fig. 4 as an example, the number of the pixel units 21 may preferably decrease linearly in sequence, so that it can be ensured that the number of the pixel units 21 of each portion of the flexible display panel 100 can be distributed more uniformly when the panel is stretched. For example, the number of the pixel units 21 of the adjacent pixel island regions 2 arranged in the set direction may be 8, 6, and 4. For another example, in other embodiments, the number of the pixel units 21 in the adjacent pixel island regions 2 arranged along the setting direction may be 12, 10, 9, 8, 6, 4, and the like. And is not limited thereto.
It can be understood that when the flexible display panel 100 shown in fig. 4 is used, after the flexible display panel 100 is transversely stretched, since the PPI of the pixel island region 2 near the middle of the flexible display panel 100 before stretching is high, the overall PPI of the flexible display panel 100 after stretching can be as consistent as possible, thereby improving the overall display effect of the flexible display panel 100.
The second design may be performed for a flexible display panel with a requirement of longitudinal stretching, as shown in fig. 5, when the flexible display panel 100 is stretched longitudinally, the axis may be a transverse axis L2 of the substrate 1. So designed, when the flexible display panel 100 is stretched in the arrow direction of fig. 5, the number of pixel cells 21 in the pixel island region 2 closer to the middle of the substrate 1 is larger. Accordingly, the larger the number of pixel cells 21 in the pixel island region 2 corresponding to the region having the larger amount of deformation, the more uniformly the pixel cells 21 can be distributed as much as possible after the substrate 1 is subjected to tensile deformation. Therefore, the distribution uniformity of the pixel units 21 of the flexible display panel 100 after longitudinal stretching can be ensured as much as possible, and the problem of reduced display effect, such as unclear display picture, caused by large reduction of the PPI of the substrate 1 near the middle region can be avoided.
In some embodiments, the number of pixel units 21 in the adjacent pixel island regions 2 arranged along the set direction decreases linearly or non-linearly in sequence. Preferably, in this embodiment, taking fig. 5 as an example, the number of the pixel units 21 may be sequentially decreased linearly. For example, the number of the pixel units 21 of the adjacent pixel island regions 2 arranged in the set direction may be 8, 6, and 4. For another example, in other embodiments, the number of the pixel units 21 of the adjacent pixel island regions 2 arranged along the set direction may be 12, 10, 9, 8, 6, 4, and the like. And is not limited herein.
It can be understood that when the flexible display panel 100 shown in fig. 5 is used, after the flexible display panel 100 is longitudinally stretched, since the PPI of the pixel island region 2 near the middle of the flexible display panel 100 before stretching is higher, the PPI of the flexible display panel 100 as a whole can be as consistent as possible after stretching, thereby improving the overall display effect of the flexible display panel and ensuring the definition of the overall display.
The third design scheme can be carried out on the flexible display panel with the requirement of stretching in the transverse direction and the longitudinal direction. In this embodiment, the requirement of stretching in the transverse and longitudinal directions may be understood as stretching the flexible display panel as a whole. In this embodiment, as shown in fig. 6, the setting direction may be a direction extending from the middle of the substrate 1 to the edge of any one side of the substrate 1, and the setting direction may be understood as a radial direction having the middle of the substrate 1 as a radiation center, for example, directions d1, d2, d3,. gtoreq, d8, and the like.
Further, the pixel unit 21 of the flexible display panel 100 shown in fig. 6 may be designed as follows: the greater the number of pixel cells 21 in the pixel island region 2 closer to the middle of the substrate 1. For example, the number of pixel cells 21 of the pixel island region 2a in the middle of the substrate 1 is the largest, the number of pixel cells 21 of the pixel island region 2b surrounding the pixel island region 2a is reduced by a portion, and the number of pixel cells 21 of the pixel island region 2c surrounding the pixel island region 2b is reduced by a portion. For another example, the number of pixel cells 21 of the pixel island region 2a may be 16, the number of pixel cells 21 of the pixel island region 2b may be 9, and the number of pixel cells 21 of the pixel island region 2c may be 4.
In the present embodiment, the pixel island regions 2a can be regarded as radial centers, the ring-shaped regions formed between the pixel island regions 2b can be regarded as first ring-shaped regions, and the ring-shaped regions formed between the pixel island regions 2c can be regarded as second ring-shaped regions. It is understood that the annular region closer to the radiation center corresponds to a larger number of pixel cells 21 in the pixel island region 2.
It can be understood that when the flexible display panel 100 is stretched in the direction of the arrow in fig. 6, since the number of pixel units 21 in the pixel island region 2a near the middle of the substrate 1 is larger, and accordingly, the number of pixel units 21 in the pixel island region 2 corresponding to the region with the larger deformation amount is larger, the pixel units 21 can be uniformly distributed as much as possible after the substrate 1 is subjected to stretching deformation. Therefore, the distribution uniformity of the pixel units 21 of the flexible display panel 100 after longitudinal stretching can be ensured as much as possible, and the problems of unclear display picture and reduced display effect such as distortion of the display picture caused by large PPI reduction in the middle region of the substrate 1 can be avoided.
In practical implementations, the linear function of the linear increment of the number of pixel units 21 may be f1 ═ a × x or the nonlinear function f2 ═ x 2. Wherein, a and x can be both positive integers, x can be the number of the pixel island region 2, and the number of the pixel island region 2 can decrease along the setting direction.
Taking fig. 4 as an example, the number of pixel units 21 may be determined by using a linear function f1 ═ a × x, and the number of the pixel island region 2 in the middle region of the substrate 1 may be 4, so that the number of corresponding pixel units 21 may be 4a, and if a takes 2, the number of corresponding pixel units 21 may be 8. The number of the pixel island region 2 adjacent to the pixel island region 2 of the central region of the substrate 1 may be 3, and the number of the corresponding pixel units 21 may be 6. It is understood that the value of a can be flexibly selected according to the stretching range of the flexible display panel 100, and is not limited herein.
Taking fig. 6 as an example, a non-linear function f2 ═ x may be used2The determination of the number of the pixel units 21 is performed, and the number of the pixel island region 2a may be 4, the number of the corresponding pixel units may be 16, the number of the pixel island region 2b may be 3, the number of the corresponding pixel units may be 9, the number of the pixel island region 2c may be 2, and the number of the corresponding pixel units may be 4.
It should be understood that the above-mentioned functions are only examples, and in practical implementation, parameter adjustment and optimization of the above-mentioned linear functions can be achieved by taking into account deformation parameters (e.g., elastic modulus) of the substrate. For a non-linear distribution of the number of pixel cells 21, a number of iterative analyses may be performed to determine the number of pixel cells 21 of the corresponding pixel island region 2 based on the deformation parameter of the substrate.
On the basis of the three designs described above, the areas of the different pixel island regions 2 can also be adaptively adjusted in order to ensure efficient wiring and packaging for each pixel cell 21.
Referring to fig. 7, based on the first design, the areas of the pixel island regions 2 arranged along the longitudinal axis L1 in the direction extending toward the edge of the substrate 1 may be sequentially decreased, so that the area of the pixel island region 2 including more pixel units 21 is larger, which facilitates the later wiring of the pixel units 21 and the packaging of the entire pixel island region 2, and avoids the problem that the area of the pixel island region 2 is too small to cause difficulty in wiring of the pixel units 21.
Similarly, referring to fig. 8, based on the second design, the areas of the pixel island regions 2 arranged in the direction extending from the lateral axis L2 to the edge of the substrate 1 may be designed to decrease in sequence. Referring to fig. 9, based on the third design, the areas of the pixel island regions 2 arranged along the direction extending from the middle of the substrate 1 to the edge of any side of the substrate 1 may be designed to decrease sequentially. It is to be understood that the area of the pixel island region 2 may be designed to decrease linearly or non-linearly, and the present embodiment may preferably decrease linearly. The area differential design mode of the pixel island region 2 can be flexibly selected according to actual conditions, and is not limited herein.
Further, in practical implementation, the inventors found that the stretching deformation amplitude of the flexible display panel 100 is reduced from the middle to the periphery, and based on this, in order to further ensure the orderly arrangement of the pixel units 21 in the flexible display panel 100 after stretching, so as to ensure the global display effect, the distance between the pixel units 21 in each pixel island region 2 may also be designed differently. For this reason, the distance between the adjacent pixel units in each pixel island region arranged in the set direction may be designed to be increased.
Referring to fig. 10, if the flexible display panel 100 is used in a state of being stretched in the transverse direction, for each row of pixel units 21, the distances between adjacent pixel units 21 arranged in the direction of the two side edges of the substrate 1 increase in sequence from the pixel unit 21a at the longitudinal axis L1 as a starting pixel unit. For example, the distance Wab between the pixel cell 21a and the pixel cell 21b is smaller than the distance Wbc between the pixel cell 21b and the pixel cell 21c, and so on. By doing so, when the flexible display panel 100 is stretched in the transverse direction, the closer the distance between the pixel units 21 is to the longitudinal axis L1, the greater the deformation of the portion of the substrate 1 closer to the longitudinal axis L1, and thus it can be ensured that the pixel units 21 in the flexible display panel 100 can be arranged as neatly as possible after the flexible display panel 100 is stretched in the transverse direction.
For convenience of illustration, referring to fig. 10, before the flexible display panel 100 is stretched in the transverse direction, the distance between each row of pixel units 21a and 21b is Wab, the distance between each row of pixel units 21f and 21g is Wfg, and Wab is smaller than Wfg. After the flexible display panel 100 is transversely stretched, the distance between each row of the pixel units 21a and the pixel units 21b becomes W 'ab, and the distance between each row of the pixel units 21f and the pixel units 21g becomes W' fg, since the distance between each row of the pixel units 21a and the pixel units 21b changes greatly during the stretching process and the distance between each row of the pixel units 21f and the pixel units 21g changes less during the stretching process, after the flexible display panel 100 is transversely stretched, W 'ab and W' fg can be nearly the same, and thus, it can be ensured that the pixel units 21 in the flexible display panel 100 can be arranged neatly as possible after the flexible display panel 100 is transversely stretched.
Similarly, referring to fig. 11 and fig. 12 in combination, when the flexible display panel 100 is used in a laterally stretched state or a wholly stretched state, the distance of the pixel unit 21 can be set according to the same design concept as that of fig. 10, which is not described herein again. In addition, the distance between adjacent pixel units in each pixel island region arranged along the set direction may also be designed to be linearly or non-linearly increasing, and may preferably be linearly increasing, which is not limited herein.
In some examples, the distance between adjacent pixel island regions 2 arranged in a set direction may also be designed differently. For example, the distance between adjacent pixel island regions 2 arranged in a set direction may be designed to be sequentially increased. Wherein, the linear increment and/or the non-linear increment can be selected for design. With this configuration, after the flexible display panel 100 is stretched, it is possible to ensure that the pixel island regions 2 in the flexible display panel 100 are arranged as orderly as possible.
In an actual implementation process, for the above scheme of improving the display effect of the stretched flexible display panel 100, the number-difference design of the pixel cells 21 in the pixel island region 2 at different positions of the substrate 1 may be used alone, or may be used in combination with the area-difference design of the pixel island region 2, the distance-difference design of the pixel island region 2, or the distance-difference design of the pixel cells 21, when performing the difference design of the number of the pixel cells 21, the area of the pixel island region 2, the distance of the pixel island region 2, and the distance of the pixel cells 21, a linear difference design or a nonlinear difference design may be flexibly selected, and there are many corresponding combination modes, which are not listed one by one here. In addition, it is also possible to design different numerical value ranges for different designs of the number of the pixel cells 21, the area of the pixel island region 2, the distance of the pixel island region 2, and the distance of the pixel cells 21.
For the design of the difference of the number of the pixel units 21, the first ratio between the total number of the pixel units 21 in the first pixel island region and the total number of the pixel units 21 in the second pixel island region may be 1.5-5. The first pixel island region is a pixel island region with the largest number of corresponding pixel units 21, and the second pixel island region is a pixel island region with the smallest number of corresponding pixel units 21. For example, in fig. 4, the first ratio may be 8/4-2, and for example, in fig. 6, the first ratio may be 16/4-4. Of course, in practical implementation, the first ratio may also be adjusted according to the design requirement of the actual pixel unit 21, for example, the first ratio may be 1.5, 2, 2.5, 3, 3.5, 4, 4.5 or 5, which is not limited herein.
For the area differentiation design of the pixel island region 2, the second ratio between the area of the first pixel island region and the area of the second pixel island region may be 1-4. Taking fig. 4 as an example, the second ratio between the area of the first pixel island region and the area of the second pixel island region may be 1, and taking fig. 8 as an example, the second ratio between the area of the first pixel island region and the area of the second pixel island region may be 4. Of course, in practical implementation, the second ratio may be adaptively adjusted according to practical requirements, for example, the second ratio may be 1, 1.5, 2, 2.5, 3, 3.5 or 4, and is not limited herein.
For the design of distance differentiation of the pixel island regions 2, a third ratio of the maximum distance between adjacent pixel island regions to the minimum distance between adjacent pixel island regions may be 0.9 to 1.5. For example, the third ratio may be selected to be 0.9, 1, 1.1, 1.2, 1.3, 1.4, or 1.5, which is not limited herein.
For the design of distance differentiation of the pixel cells 21, a fourth ratio of the maximum distance between the adjacent pixel cells 21 in each pixel island region 2 arranged along the set direction to the minimum distance between the adjacent pixel cells 21 in the pixel island region 2 may be 0.9 to 1.5. For example, the fourth ratio may be selected to be 0.9, 1, 1.1, 1.2, 1.3, 1.4, or 1.5, but is not limited thereto.
On the basis of the above embodiments, the embodiment of the present invention further provides an electronic device, which may include the flexible display panel 100 described above. The electronic device may be a wearable display device such as a smart watch, a smart bracelet, or an on-vehicle display device, which is not limited herein. The electronic device has better display effect under different stretching states of the flexible display panel 100.
To sum up, the flexible display panel 100 and the electronic device provided in the embodiment of the invention perform differentiated setting on the number of the pixel units 21 in the pixel island region 2 on the substrate 1 of the flexible display panel 100, so that the number of the pixel units 21 of the adjacent pixel island regions 2 arranged along the set direction is sequentially decreased progressively. In this way, after the flexible display panel 100 is stretched, the uniformity of the distances between the pixel units 21 arranged along the set direction can be ensured as much as possible, and the problem that the display effect of the stretched flexible display panel 100 is reduced in the region where the stretching deformation of the flexible display panel 100 is too large due to the fact that the distance between the pixel units 21 in the region is too large in a partial region of the flexible display panel 100 is avoided.
