Description

Technical Field

[0001] This application relates to the field of display technologies, and in particular, to a display panel and a display device. Background Art

[0002] The brightness and power consumption of a display panel are usually positively correlated. That is, the higher the brightness of the display panel, the higher its power consumption. In related technologies, when it is necessary to present a brightness difference in different display areas of the display panel, usually only the power consumption of some areas can be increased, so that the brightness of these areas increases. However, as the power consumption of these areas increases, the overall energy consumption of the display panel also increases, thereby reducing the battery life of the display panel. Summary of the Invention

[0003] Embodiments of this application provide a display panel and a display device to solve the problem in related technologies that the battery life of the display panel is reduced due to adjusting the power consumption to achieve brightness differences in different display areas.

[0004] On the one hand, embodiments of this application provide a display panel. The display panel has a first display area and a second display area, and the display panel includes:

[0005] An array substrate;

[0006] A plurality of first pixels and a plurality of first lenses located in the first display area, each of the first lenses being correspondingly disposed on the side of one of the first pixels facing away from the array substrate; and

[0007] A plurality of second pixels and a plurality of second lenses located in the second display area, each of the second pixels including at least three sub-pixels, and each of the second lenses being correspondingly disposed on the side of one of the sub-pixels facing away from the array substrate;

[0008] Wherein, the orthographic projection area of the first lens on the array substrate is larger than the orthographic projection area of the second lens on the array substrate.

[0009] In some embodiments, the orthographic projection area of the first lens on the array substrate is greater than or equal to the sum of the orthographic projection areas of the plurality of second lenses corresponding to one second pixel on the array substrate.

[0010] In some embodiments, each of the first pixels includes one sub-pixel, and the pixel density of the sub-pixels located in the second display area is greater than the pixel density of the sub-pixels located in the first display area.

[0011] In some embodiments, the ratio of the pixel density of the sub-pixels located in the second display area to the pixel density of the sub-pixels located in the first display area is greater than or equal to 3.

[0012] In some embodiments, each of the second pixels includes three sub-pixels, and the three sub-pixels are configured to emit light of different colors. In each of the second pixels, the line connecting the geometric centers of the three sub-pixels forms an isosceles triangle.

[0013] In some embodiments, a plurality of the second pixels are arranged in an array in the second display area, and the second display area includes a plurality of sub-pixel rows and a plurality of sub-pixel columns; wherein, the plurality of sub-pixels in each sub-pixel row have the same light-emitting color; in each sub-pixel column, any two adjacent sub-pixels have different light-emitting colors.

[0014] In some embodiments, the focal point of the first lens coincides with the geometric center of the corresponding first pixel.

[0015] In some embodiments, the focal point of the second lens coincides with the geometric center of a corresponding sub-pixel in the second pixel.

[0016] In some embodiments, each of the first pixels includes one sub-pixel, and the sub-pixels located in the first display area are configured to emit light of the same color; at least three of the sub-pixels in each of the second pixels are configured to emit light of different colors.

[0017] In some embodiments, the display panel further has a third display area, and the display panel further includes a plurality of third pixels and a plurality of third lenses located in the third display area. Each of the third lenses is disposed on a side of the corresponding third pixel facing away from the array substrate; wherein, the orthographic projection area of the third lens on the array substrate is larger than the orthographic projection area of the second lens on the array substrate, and the light-emitting color of the third pixel is different from that of the first pixel.

[0018] In some embodiments, each of the third pixels includes one sub-pixel, and the sub-pixels located in the third display area emit light of the same color; the sub-pixels in the third display area and the sub-pixels in the first display area emit red light and green light respectively.

[0019] On the other hand, an embodiment of the present application further provides a display device, and the display device includes the display panel as described in any of the above embodiments.

[0020] For the display panel provided by the embodiments of the present application, since the first lens corresponding to the first pixel has a relatively larger orthographic projection area than the second lens corresponding to the sub-pixel, the first lens can converge light at a relatively larger angle, thus having better light extraction efficiency. Therefore, the brightness presented by the first pixel is higher than that of the corresponding sub-pixel in the second pixel, so that the first display area and the second display area can have different brightnesses, thus meeting the display requirements of the display panel. For example, the display panel can be applied to a head-up display system. By distinguishing the brightness of different areas, some display areas can be made more prominent to attract the driver's attention. Description of the Drawings

The described technical solutions are only used to explain and illustrate the idea of the present application, and should not be regarded as a limitation on the protection scope of the present application.

The term "plurality" and similar words mean two or more, unless otherwise clearly defined.

[0037] The use of "suitable for" or "configured to" in the present application means open and inclusive language, which does not exclude a device suitable for or configured to perform additional tasks or steps. In addition, the use of "based on" means open and inclusive, because a process, step, calculation or other action "based on" one or more of the stated conditions or values may in practice be based on additional conditions or values beyond the stated ones.

[0038] In the present application, the word "exemplary" is used to mean "serving as an example, illustration, or description". Any embodiment described as "exemplary" in the present application is not necessarily construed as being more preferred or having more advantages than other embodiments. The following description is given to enable any person skilled in the art to implement and use the present application.

[0039] The various embodiments of the present application are similar, and the features in different embodiments and / or different examples can be combined with each other.

[0040] Some embodiments of the present application provide a display panel, such as Figures 1 to 3As shown in the figure, the display panel 100 has a first display area A1 and a second display area A2. The display panel 100 includes an array substrate 10, a plurality of first pixels 21 and a plurality of first lenses 31 located in the first display area A1, and a plurality of second pixels 22 and a plurality of second lenses 32 located in the second display area A2.

[0041] Each first lens 31 is correspondingly disposed on one side of a first pixel 21 facing away from the array substrate 10. After the light emitted by each first pixel 21 is modulated by the corresponding first lens 31, it can converge in the direction of the optical axis of the first lens 31, thereby improving the light extraction efficiency of the first pixel 21.

[0042] Each second pixel 22 includes at least three sub-pixels 201, and each second lens 32 is correspondingly disposed on one side of one of the sub-pixels 201 facing away from the array substrate 10. By disposing each second lens 32 on one side of a sub-pixel 201 facing away from the array substrate 10, the light emitted by the sub-pixel 201 can be modulated, so that the light converges in the direction of the optical axis of the second lens 32, thereby improving the light extraction efficiency of each sub-pixel 201.

[0043] Among them, the orthographic projection area of the first lens 31 on the array substrate 10 is larger than the orthographic projection area of the second lens 32 on the array substrate 10. Herein, the orthographic projection refers to the projection along the thickness direction Z of the display panel 100.

[0044] Since the first lens 31 corresponding to the first pixel 21 has a relatively larger orthographic projection area than the second lens 32 corresponding to the sub-pixel 201, the first lens 31 can converge light at a relatively larger angle, thus having a better light extraction efficiency. Therefore, the brightness presented by the first pixel 21 is higher than that of the corresponding sub-pixel 201 in the second pixel 22. In this way, the first display area A1 and the second display area A2 can have different brightnesses, so as to meet the display requirements of the display panel 100. For example, the display panel 100 can be applied to a head-up display system. By differentiating the brightness of different areas, some display areas can be made more prominent to attract the driver's attention. Exemplarily, the display area can be used to display map road signs, warning slogans, vehicle speed information, etc.

[0045] Therefore, for the display panel 100 provided in the embodiments of the present application, due to the different sizes of the first lens 31 and the second lens 32, different degrees of light concentration can be achieved for the pixels (or sub-pixels) in different areas. Furthermore, the brightness difference between the first display area A1 and the second display area A2 can be realized without adjusting the power consumption. In this way, it can be ensured that the display panel 100 has good battery life while presenting different brightness pictures in different areas.

[0046] In some embodiments, as Figure 3 shown, the orthographic projection area of the first lens 31 on the array substrate 10 is greater than or equal to the sum of the orthographic projection areas of a plurality of second lenses 32 corresponding to one second pixel 22 on the array substrate 10.

[0047] As an example, the second pixel 22 includes three sub-pixels 201. In this case, the three second lenses 32 corresponding to the second pixel 22 are respectively located above the three sub-pixels 201, and each second lens 32 covers a corresponding sub-pixel 201. The first lens 31 has a first projection area P1 on the array substrate 10, and the three second lenses 32 have a second projection area P2, a third projection area P3, and a fourth projection area P4 on the array substrate 10 respectively, and the area of the first projection area P1 is greater than or equal to the sum of the areas of the second projection area P2, the third projection area P3, and the fourth projection area P4. For example, the first projection area P1, the second projection area P2, the third projection area P3, and the fourth projection area P4 may all be circular.

[0048] Since the first lens 31 corresponding to the first pixel 21 has a larger orthographic projection area than the plurality of second lenses 32 corresponding to the second pixel 22, the difference in the orthographic projection areas between the first lens 31 and the second lenses 32 is made larger, so that the brightness difference between the first display area A1 and the second display area A2 can be further increased, thereby meeting the usage scenario requirements of the display panel 100.

[0049] In some embodiments, as Figure 4 shown, at least three sub-pixels 201 included in each second pixel 22 are used to emit light of different colors. For example, the three sub-pixels 201 in each second pixel 22 can respectively emit red light, green light, and blue light, so that a color picture display of the second display area A2 can be realized.

[0050] When the second display area A2 is applied to a head-up display system, the second display area A2 can display arrow road sign navigation information, or vehicle own information, etc. In addition, the second display area A2 can also be used as an information interaction area, so that the driver can interact after viewing the corresponding information.

[0051] It should be noted that in Figure 4Among them, the right half region corresponds to the second display area A2. Sub-pixels 201 with the same pattern filling in the right half region emit light of the same color, and sub-pixels 201 with different pattern fillings emit light of different colors. In some examples, each second pixel 22 may include four sub-pixels 201, where three sub-pixels respectively emit red light, green light, and blue light, and another sub-pixel may emit white light, so as to ensure the display of a color picture in the second display area A2. In some embodiments, as Figure 3 and Figure 4 shown, each first pixel 21 includes a sub-pixel 201, and the sub-pixels 201 located in the first display area A1 are used to emit light of the same color.

[0052] In this case, the first display area A1 can be used to achieve monochromatic display, so that the number of sub-pixels 201 can be reduced, thereby saving the manufacturing cost of the display panel 100. And since the sub-pixels 201 located in the first display area A1 can correspond one-to-one with the first lenses 31, this is also beneficial to ensuring the light extraction efficiency of each sub-pixel 201.

[0053] As an example, in the CIE 1931 chromaticity diagram, the color coordinates of red are (X1, Y1), where 0.6 ≤ X1 ≤ 0.72 and 0.28 ≤ Y1 ≤ 0.4; the color coordinates of green are (X2, Y2), where 0.15 ≤ X2 ≤ 0.3 and 0.55 ≤ Y2 ≤ 0.8; the color coordinates of red are (X3, Y3), where 0.08 ≤ X3 ≤ 0.2 and 0.02 ≤ Y3 ≤ 0.12.

[0054] In some examples, the sub-pixels 201 located in the first display area A1 emit green light or red light.

[0055] As an example, the sub-pixels 201 located in the first display area A1 emit green light. In this case, the first display area A1 is used to achieve a green picture display. Green has a high contrast in the visual perception of the human eye, so it is convenient for users to view under different lighting conditions (such as strong light, weak light, or night environment). For example, the first display area A1 can be used as the vehicle speed area of a head-up display system, and the driving speed of the vehicle can be displayed in this vehicle speed area. The green picture can display the vehicle speed information more clearly and reduce the visual fatigue of the driver.

[0056] In some other examples, the sub-pixel 201 located in the first display area A1 emits red light. In this case, the first display area A1 is used to implement the display of a red picture. Red is a color with high saturation that can quickly attract the user's attention, thus achieving a warning effect; moreover, red has a high contrast under different lighting conditions, ensuring that the display information of the picture is clearly visible. For example, the first display area A1 can be used as a warning area of the head-up display system, and information such as lane deviation and warning of collision of the vehicle can be displayed in this warning area. The red picture can immediately alert the driver, thus facilitating the driver to quickly identify potential dangerous situations and make corresponding responses.

[0057] In some embodiments, the area of the first display area A1 is smaller than the area of the second display area A2. As an example, the area of the first display area A1 is 1 / 4 of the area of the second display area A2. Such a setting can enable the display panel 100 to have a smaller area to display a green or red picture, thus playing a reminder or warning role, while the other larger area is used for color picture display, thereby ensuring that the display panel 100 has a larger information transmission volume and improving the user experience.

[0058] In some embodiments, as Figure 5 and Figure 6 shown, the display panel 100 further has a third display area A3. The display panel 100 further includes a plurality of third pixels 23 and a plurality of third lenses 33 located in the third display area A3. Each third lens 33 is disposed on the side of the corresponding third pixel 23 away from the array substrate 10. Among them, the orthographic projection area of the third lens 33 on the array substrate 10 is larger than the orthographic projection area of the second lens 32 on the array substrate 10.

[0059] Since the third lens 33 corresponding to the third pixel 23 has a relatively larger orthographic projection area compared to the second lens 32 corresponding to the sub-pixel 201, the third lens 33 can converge light at a relatively larger angle, thus having a better light output efficiency. Therefore, the brightness presented by the third pixel 23 is higher than that of the sub-pixel 201. In this way, the third display area A3 and the second display area A2 can have different brightnesses, thus adapting to the display requirements of the display panel 100.

[0060] It should be noted that the first display area A1 and the third display area A3 can be adjacent or separated by the second display area A2. The embodiments of the present application do not limit this.

[0061] In some examples, the emission color of the third pixel 23 is different from that of the first pixel 21. This can enable the display panel 100 to have multiple display areas with different colors, thereby expanding the usage scenarios of the display panel 100 and enhancing the user experience. Moreover, since both the first display area A1 and the third display area A3 achieve higher brightness by setting lenses with a larger coverage area, the power consumption of the display panel 100 can be effectively controlled.

[0062] As an example, each third pixel 23 includes a sub-pixel 201, and the sub-pixels 201 located within the third display area A3 emit light of the same color, and the sub-pixels 201 located within the third display area A3 and the sub-pixels 201 located within the first display area A1 emit light of different colors.

[0063] Exemplarily, the sub-pixels 201 within the third display area A3 and the sub-pixels 201 within the first display area A1 emit red light and green light respectively.

[0064] In this case, the third display area A3 and the first display area A1 can serve as a warning area and a vehicle speed area respectively. That is to say, the head-up display system can have a warning area and a vehicle speed area simultaneously, so as to enrich the information scene output of the head-up display system, thereby enhancing the driving experience of the driver.

[0065] In some examples, the third display area A3 and the first display area A1 are adjacent, so that the driver can quickly observe the information within the warning area during the process of viewing the vehicle speed area, and thus can make corresponding countermeasures in a timely manner.

[0066] In some embodiments, the sub-pixel 201 can be a Micro LED (Light-Emitting Diode) or a MiniLED. By adopting a Micro LED or a Mini LED, high-brightness display can be achieved in the corresponding display area, and at the same time, the light is modulated in cooperation with the corresponding lens, so as to ensure that different display areas of the display panel 100 have high brightness to meet its different scenario requirements.

[0067] In some embodiments, such as Figure 3 and Figure 4As shown, the pixel density of the sub-pixel 201 located in the second display area A2 is greater than that of the sub-pixel 201 located in the first display area A1. That is, within a unit area, the number of sub-pixels 201 in the second display area A2 is greater than that in the first display area A1. As an example, the first pixel 21 and the second pixel 22 may have the same area. Since the number of sub-pixels 201 in the second pixel 22 is relatively large, the pixel density of the sub-pixel 201 located in the second display area A2 is greater than that of the sub-pixel 201 located in the first display area A1.

[0068] In this case, since the pixel density of the sub-pixel 201 in the first display area A1 is relatively small, the first lens 31 used to cover the sub-pixel 201 in each first pixel 21 can have a larger coverage area, thus ensuring that the first lens 31 has a good light modulation effect on the corresponding sub-pixel 201, which is conducive to improving the display brightness of the first display area A1. On the other hand, since the pixel density of the sub-pixel 201 in the second display area A2 is relatively large, within the second display area A2, the sub-pixel 201 has a relatively high density, which can improve the fineness of the picture display in the second display area A2, and thus enhance the user's viewing experience.

[0069] In some embodiments, please continue to refer to Figure 3 and Figure 4 , the ratio of the pixel density of the sub-pixel 201 located in the second display area A2 to the pixel density of the sub-pixel 201 located in the first display area A1 is greater than or equal to 3. In this case, compared with the case where the ratio of the pixel density of the sub-pixel 201 in the second display area A2 to the pixel density of the sub-pixel 201 in the first display area A1 is 2, the PPI (Pixels Per Inch) in the second display area A2 can be increased by more than 22%, and the detail expressiveness can be improved by more than 30%. And the color gamut coverage rate in the second display area A2 can be increased from 90% to more than 95%, and the color error can be reduced from 3.0 to below 2.5, so as to ensure the picture display effect of the second display area A2.

[0070] In some examples, when each second pixel 22 includes three sub-pixels 201, the ratio of the pixel density of the sub-pixel 201 located in the second display area A2 to the pixel density of the sub-pixel 201 located in the first display area A1 can be equal to 3. That is, the areas of the first pixel 21 and the second pixel 22 are equal, but the number of sub-pixels 201 in the second pixel 22 is three times that of the sub-pixels 201 in the first pixel.

[0071] In some other examples, when each second pixel 22 includes four sub-pixels 201, the ratio of the pixel density of the sub-pixels 201 located within the second display area A2 to the pixel density of the sub-pixels 201 located within the first display area A1 can be equal to 4. That is to say, the areas of the first pixel 21 and the second pixel 22 are equal, but the number of sub-pixels 201 in the second pixel 22 is four times the number of sub-pixels 201 in the first pixel.

[0072] In some embodiments, please continue to refer to Figure 3 and Figure 4 , each second pixel 22 may include three sub-pixels 201, which are used to emit light of different colors, and the connection line of the geometric centers of the three sub-pixels 201 is an isosceles triangle.

[0073] With such an arrangement, by arranging the three sub-pixels 201 in the form of an isosceles triangle, the three sub-pixels can be arranged relatively closely, so that a larger number of sub-pixels 201 can be set under the same area, thereby improving the display resolution.

[0074] In some examples, each second pixel 22 may include a first sub-pixel, a second sub-pixel, and a third sub-pixel. Among them, the length of the connection line between the geometric centers of the first sub-pixel and the second sub-pixel is equal to the length of the connection line between the geometric centers of the second sub-pixel and the third sub-pixel, and is not equal to the length of the connection line between the geometric centers of the first sub-pixel and the third sub-pixel. That is to say, in the isosceles triangle, the length of one side is not equal to the lengths of the other two sides. As an example, the connection line of the geometric centers of the three sub-pixels 201 can be an isosceles right triangle.

[0075] Since the length of one side in the isosceles triangle is not equal to the lengths of the other two sides, on the one hand, it can adapt to the curved display panel or the special-shaped display panel, reducing pixel waste; on the other hand, it can also match the sensitivity difference of the human eye to the resolution in the horizontal and vertical directions (the human eye is more sensitive to horizontal details), thereby optimizing the rendering efficiency of the display screen.

[0076] In some examples, the connection line of the geometric centers of the three sub-pixels 201 can be an equilateral triangle. That is to say, in each second pixel 22, the length of the connection line between the geometric centers of any two sub-pixels is equal.

[0077] With such an arrangement, the color consistency under a wide viewing angle can be optimized. And, since the geometric center distances of the three sub-pixels 201 in each second pixel 22 are equal, the second lenses 32 corresponding to these sub-pixels 201 can all have a large coverage area, thereby effectively improving the light-emitting brightness of the second pixel 22.

[0078] In some examples, the orthographic projection areas of the multiple second lenses 32 corresponding to each second pixel 22 on the array substrate 10 are equal. This can ensure that the multiple sub-pixels 201 in each second pixel 22 have good luminous brightness, thereby ensuring that the second pixel 22 has good luminous brightness.

[0079] In some embodiments, please continue to refer to Figure 3 and Figure 4 , the multiple second pixels 22 are arranged in an array in the second display area A2. That is, the multiple second pixels 22 are arranged in multiple rows and multiple columns in the second display area A2. The second display area A2 is provided with multiple sub-pixel rows and multiple sub-pixel columns. Among them, each sub-pixel row includes multiple sub-pixels 201 arranged along the row direction X, and each sub-pixel column includes multiple sub-pixels 201 arranged along the column direction Y.

[0080] The luminous colors of the multiple sub-pixels 201 in each sub-pixel row are the same. And in each sub-pixel column, the luminous colors of any two adjacent sub-pixels 201 are different.

[0081] Such a setting can make some sub-pixels 201 shared by multiple second pixels 22, so that the pixel density of the second display area A2 can be increased, thereby improving the display clarity of the second display area A2. In addition, in the row direction X and the column direction Y, the distances between the geometric centers of any two adjacent sub-pixels 201 can be equal, so as to ensure the display effect of the second display area A2.

[0082] As an example, in the row direction X and the column direction Y, the distances between the geometric centers of any two adjacent second lenses 32 are equal, so as to ensure that the second display area A2 has a good display effect.

[0083] In some examples, the size of the first lens 31 can be greater than or equal to 10 μm and less than or equal to 300 μm. In addition, two adjacent first lenses 31 can be connected or arranged at intervals. When two adjacent first lenses 31 are arranged at intervals, the distance between them can be greater than or equal to 2 μm and less than or equal to 10 μm.

[0084] In some embodiments, as Figure 2 shown, the focal point F1 of the first lens 31 coincides with the geometric center O1 of the corresponding first pixel 21 (for example, the sub-pixel 201 in the first pixel 21). This can ensure that the first lens 31 has a good modulation effect on the light of the first pixel 21, thereby improving the light extraction efficiency of the first pixel 21.

[0085] In some examples, the distance between the geometric center of the first lens 31 and the geometric center O1 of the corresponding first pixel 21 (such as the sub-pixel 201 in the first pixel 21) can be greater than or equal to 1 μm and less than or equal to 300 μm, and it can be adjusted as needed.

[0086] In some embodiments, please continue to refer to Figure 2 , the focal point F2 of the second lens 32 coincides with the geometric center O2 of a corresponding sub-pixel 201 in the second pixel 22. In this way, it can be ensured that the first lens 31 forms a good light modulation effect on the corresponding sub-pixel 201 in the second pixel 22, thereby improving the light extraction efficiency of the second pixel 22.

[0087] In some examples, the distance between the geometric center of the second lens 32 and the geometric center O2 of a corresponding sub-pixel 201 in the second pixel 22 can be greater than or equal to 1 μm and less than or equal to 300 μm, and it can be adjusted as needed.

[0088] In some embodiments, a first encapsulation part is provided in the first display area A1, and the first encapsulation part is located between the first lens 31 and the corresponding first pixel 21; a second encapsulation part is provided in the second display area, and the second encapsulation part is located between the second lens 32 and the corresponding sub-pixel 201 in the second pixel 22. Since the size of the first lens 31 is different from that of the second lens 32, the thickness of the first encapsulation part can be greater than the thickness of the second encapsulation part, so as to effectively ensure that the focal point F1 of the first lens 31 coincides with the geometric center O1 of the corresponding first pixel 21. In addition, since the thickness of the second encapsulation part is relatively small, this is beneficial to reducing the light mixing between different sub-pixels 201 in the second pixel 22, thereby reducing light crosstalk and improving the picture display effect of the second display area A2.

[0089] Some embodiments of the present application further provide a display device, as Figure 7 shown, the display device 1000 includes the display panel 100 described in any of the above embodiments.

[0090] Since it includes the display panel 100, the display device 1000 has the technical effects of the above display panel 100, which will not be elaborated here.

[0091] In some examples, the display device 1000 further includes a mounting bracket 200, and the mounting bracket 200 can mount and support the display panel 100 to facilitate the use of the display panel 100.

[0092] The display device 1000 can be a watch or a display device applied to a head-up display system. When the display device 1000 is a watch, since the first lens 31 has a relatively large orthographic projection area, the brightness of the first display area A1 can be enhanced, thus meeting the brightness requirements of the watch (usually above 1000 nits). When the display device 1000 is applied to a head-up display system, the brightness of the first display area A1 can meet the brightness requirements of the head-up display system. At the same time, since the head-up display system usually magnifies the image displayed by the display device 1000, for example, an image of less than 5 inches can be magnified to dozens of inches. Therefore, the first display area A1 can be set to a relatively small area, so that the image displayed in this area can serve as a reminder or warning.

[0093] The embodiments of the present application have been introduced in detail above. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
