Description

Technical Field

[0001] This application relates to the field of displays, specifically to a display panel. Background Technology

[0002] Major panel manufacturers are actively developing light-emitting diode (LED) display panels (or Mini-LED panels, or MicroLED panels), especially miniature LED display panels (MinLED or MicroLED panels), which are expected to become the core technology of next-generation display panels. Because LEDs (or Mini-LEDs, or MicroLEDs) experience a certain degree of brightness decay when operating at high contrast and high brightness for extended periods, this leads to uneven brightness in LED display panels. Therefore, a method has been developed to address this issue by placing a photosensor above each sub-pixel containing the LED. The photosensor can detect the brightness of the LEDs in the sub-pixel, enabling automatic brightness detection and compensation for each sub-pixel.

[0003] However, current LED display panels suffer from the problem of light interference between adjacent LEDs. When LEDs in different sub-pixels emit light, the light emitted by the LED in an adjacent sub-pixel can enter the photosensitive sensor when the photosensitive sensor of the LED in one sub-pixel is detecting brightness, causing brightness interference. As a result, the photosensitive sensor of the LED in one sub-pixel can receive light emitted by the LED in the adjacent sub-pixel, making the brightness detected by the photosensitive sensor inaccurate and unable to accurately compensate for the brightness of the LEDs. Consequently, the uneven brightness of the display panel cannot be eliminated. Summary of the Invention

[0004] This application provides a display panel that can solve the problem that in a light-emitting diode (LED) display panel, the brightness detected by the photosensitive sensor is inaccurate due to the mutual interference of light from adjacent LEDs, making it impossible to accurately compensate for the brightness of the LEDs and thus preventing the elimination of uneven brightness in the display panel.

It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0033] Example 1

[0034] Please see Figures 1 to 6 , Figure 1 This is a schematic diagram of a first cross-sectional structure of a display panel 100 provided in an embodiment of this application; Figure 2 This is a schematic diagram of a second cross-sectional structure of a display panel 100 provided in an embodiment of this application; Figure 3 This is a schematic diagram of a third cross-sectional structure of a display panel 100 provided in an embodiment of this application; Figure 4 This is a schematic diagram of a fourth cross-sectional structure of a display panel 100 provided in an embodiment of this application; Figure 5 A fifth cross-sectional structural diagram of a display panel 100 provided in an embodiment of this application;

[0035] Figure 6 This is a top view of a display panel 100 provided in an embodiment of this application.

[0036] This application provides a display panel 100, which includes a driving substrate 10, a plurality of light-emitting diodes (LEDs) 20, an encapsulation cover plate 30, and a plurality of sensor groups 60. The plurality of LEDs 20 are arrayed on the driving substrate 10; the encapsulation cover plate 30 is disposed opposite to the driving substrate 10; the plurality of sensor groups 60 are disposed on the surface of the encapsulation cover plate 30 facing the LEDs 20, and each sensor group 60 corresponds to one LED 20; wherein each sensor group 60 includes a photosensitive sensor 40 and a light-blocking member 50, the light-blocking member 50 of each sensor group 60 is at least disposed on one side of a portion of the side of the photosensitive sensor 40, the material of the light-blocking member 50 includes color resist, and each light-blocking member 50 is used to block light emitted by another LED 20 adjacent to its corresponding LED 20.

[0037] Specifically, the driving substrate 10 may be provided with wiring, circuits, electrodes and other structures for driving the light-emitting diode 20. The driving substrate 10 may be an array substrate or any type of substrate for driving the light-emitting diode 20 in the prior art, and is not limited here.

[0038] Specifically, the surface of the encapsulation cover 30 may also be provided with wiring, circuits, electrodes and other structures for driving the photosensitive sensor 40, which are not limited here.

[0039] Specifically, the encapsulation cover 30 is used to encapsulate and seal the light-emitting diode 20 or the display panel 100. The base material of the encapsulation cover 30 can be glass, which is not limited here.

[0040] Specifically, multiple sensor groups 60 are disposed on the surface of the encapsulation cover plate 30 facing the light-emitting diode 20, that is, the light-emitting diode 20 and the sensor groups 60 are both disposed between the driving substrate 10 and the encapsulation cover plate 30.

[0041] Specifically, each sensor group 60 includes a photosensitive sensor 40 and a light-blocking component 50. The photosensitive sensor 40 can detect the brightness of the light-emitting diodes 20 in the sub-pixels to realize the detection and automatic compensation of the brightness of the light-emitting diodes 20 in each sub-pixel.

[0042] Specifically, each sensor group 60 is configured with a corresponding light-emitting diode 20, and each sensor group 60 is configured with a sub-pixel that is directly opposite or partially opposite to the light-emitting diode 20, which will be described in detail later.

[0043] Specifically, the material of the light-blocking component 50 includes color resist, and each light-blocking component 50 is used to block the light emitted by another light-emitting diode 20 adjacent to its corresponding light-emitting diode 20. The light-blocking component 50 effectively filters out the interfering light from the light-emitting diodes 20 in adjacent sub-pixels, so that the photosensor 40 can accurately detect the brightness of the light-emitting diode 20 in its corresponding sub-pixel. The display panel 100 can then accurately compensate for the brightness of the light-emitting diodes 20, thereby improving the brightness uniformity of the display panel 20.

[0044] Specifically, each light-blocking component 50 is used to block the light emitted by another light-emitting diode 20 adjacent to its corresponding light-emitting diode 20, for example, Figure 1 The diagram illustrates that the light-emitting diode 20 includes a first-color light-emitting diode 21, a second-color light-emitting diode 22, and a third-color light-emitting diode 23. The third-color light-emitting diode 23 and the first-color light-emitting diode 21 are arranged adjacent to each other. The interference light 71 emitted by the third-color light-emitting diode 23 is blocked by the light-blocking member 50. The interference light 71 cannot enter the photosensitive sensor 40 corresponding to the first-color light-emitting diode 21. Therefore, the photosensitive sensor 40 corresponding to the first-color light-emitting diode 21 accurately detects the brightness of the first-color light-emitting diode 21. The display panel 100 can thus accurately compensate for the brightness of the first-color light-emitting diode 21, improving the brightness uniformity of the display panel 20.

[0045] Example 2

[0046] This embodiment is the same as or similar to Embodiment 1, except that the setting of the light-blocking member 50 is further described.

[0047] In some embodiments, the light-emitting diode 20 includes at least one of a first-color light-emitting diode 21, a second-color light-emitting diode 22, and a third-color light-emitting diode 23; each light-blocking component 50 includes at least one of a first-color color resist 51, a second-color color resist 52, and a third-color color resist 53.

[0048] Specifically, the light-emitting diode 20 includes at least one of a first-color light-emitting diode 21, a second-color light-emitting diode 22, and a third-color light-emitting diode 23. In some cases, the first-color light-emitting diode 21 can be a red light-emitting diode, the second-color light-emitting diode 22 can be a green light-emitting diode, and the third-color light-emitting diode 23 can be a blue light-emitting diode, that is, the first-color light-emitting diode 21, the second-color light-emitting diode 22, and the third-color light-emitting diode 23 can be one of a red light-emitting diode, a green light-emitting diode, and a blue light-emitting diode, respectively.

[0049] The color resist is at least divided into a first color resist 51, a second color resist 52, and a third color resist 53, and each light-blocking component 50 includes at least one of the first color resist 51, the second color resist 52, and the third color resist 53. In some cases, the first color resist 51 can be a red color resist, the second color resist 52 can be a green color resist, and the third color resist 53 can be a blue color resist, that is, the first color resist 51, the second color resist 52, and the third color resist 53 can be one of a red color resist, a green color resist, and a blue color resist, respectively.

[0050] It should be noted that Figures 1 to 6 This illustrates that: the first color LED 21 is located in the first sub-pixel 201; the second color LED 22 is located in the second sub-pixel 202; and the third color LED 23 is located in the third sub-pixel 203.

[0051] It should be noted that Figures 1 to 6 The illustration shows that the first color LED 21 is the same size as the first sub-pixel 201; the second color LED 22 is the same size as the second sub-pixel 202; and the third color LED 23 is the same size as the third sub-pixel 203. However, it is not limited to this. For example, in an actual display panel, the size of the LED 20 may be smaller than the size of its corresponding sub-pixel.

[0052] Furthermore, Figure 1 This illustration shows a case where the light-blocking component 50 includes any one of a first color filter 51, a second color filter 52, and a third color filter 53. Figure 1 The diagram illustrates that the third color LED 23, the first color LED 21, and the second color LED 22 are arranged adjacent to each other in sequence. The light-blocking component 50 corresponding to the first color LED 21 is disposed on the first side 101 of the corresponding photosensitive sensor 40. The first side 101 is the side of the photosensitive sensor 40 corresponding to the first color LED that is close to the third color LED 23. At this time, the color resist included in the light-blocking component 50 corresponding to the first color LED 21 is the third color color resist 53.

[0053] Furthermore, Figure 1 This illustration shows a scenario where the light-blocking component 50 includes any one of a first color filter 51, a second color filter 52, and a third color filter 53. Figure 1 The diagram illustrates that the light-blocking member 50 of the same sensor group 60 is located on one side of a photosensitive sensor 40. The color resistance of the light-blocking member 50 is the same as the color of the light emitted by another light-emitting diode 20 adjacent to the light-emitting diode 20 on the same side as the light-blocking member 50.

[0054] In this embodiment, each light-blocking component 50 includes at least one of a first color resist 51, a second color resist 52, and a third color resist 53. Figure 1 The example illustrates a case where the light-blocking component 50 includes any one of the first color resist 51, the second color resist 52, and the third color resist 53. The light-blocking component 50 effectively filters out the interfering light from the light-emitting diodes 20 in adjacent sub-pixels, allowing the photosensitive sensor 40 to accurately detect the brightness of the light-emitting diodes 20 in the corresponding sub-pixels. As a result, the display panel 100 can accurately compensate for the brightness of the light-emitting diodes 20, thereby improving the brightness uniformity of the display panel 20.

[0055] Example 3

[0056] This embodiment is the same as or similar to the above embodiment, except that the light-blocking component includes at least a first color filter and a second color filter in a detailed description.

[0057] In some embodiments, the light-blocking member 50 includes a first color resist 501 and a second color resist 502 arranged side by side on the encapsulation cover plate 30. The first color resist 501 and the second color resist 502 are respectively one of a first color resist 51, a second color resist 52 and a third color resist 53. The first color resist 501 and the second color resist 502 are different colors.

[0058] Specifically, such as Figure 2 and Figure 3 As shown, when the light-blocking component 50 includes a first color resist 501 and a second color resist 502, the first color resist 501 and the second color resist 502 are arranged side by side on the encapsulation cover plate 30, and both the first color resist 501 and the second color resist 502 are directly arranged on the encapsulation cover plate 30.

[0059] In some embodiments, the first color resist 501 emits light of the same color as its corresponding light-emitting diode 20, and the second color resist 502 emits light of the same color as another light-emitting diode 20 adjacent to its corresponding light-emitting diode 20.

[0060] Specifically, such as Figure 2 and Figure 3 As shown, the first color resist 501 emits light of the same color as the corresponding light-emitting diode 20. For example, in the light-blocking member 50 of the sensor group 60 corresponding to the first color light-emitting diode 21, the first color resist 501 of the light-blocking member 50 emits light of the same color as the first color light-emitting diode 21.

[0061] Specifically, such as Figure 3The second color resist 502 emits light of the same color as the light emitted by the other light-emitting diode 20 adjacent to its corresponding light-emitting diode 20. For example, in the light-blocking member 50 of the sensor group 60 corresponding to the first color light-emitting diode 21, the second color resist 502 of the light-blocking member 50 emits light of the same color as the light emitted by the second color light-emitting diode 22 adjacent to the first color light-emitting diode 21.

[0062] Specifically, such as Figure 2 The second color resist 502 emits light of the same color as the light emitted by another light-emitting diode 20 adjacent to its corresponding light-emitting diode 20. For example, in the light-blocking member 50 of the sensor group 60 corresponding to the first color light-emitting diode 21, the second color resist 502 of the light-blocking member 50 emits light of the same color as the light emitted by the third color light-emitting diode 23 adjacent to the first color light-emitting diode 21.

[0063] In this embodiment, the light-blocking member 50 includes a first color resist 501 and a second color resist 502 arranged side-by-side on the encapsulation cover plate 30. The first color resist 501 in the light-blocking member 50 is used to prevent light emitted by the light-emitting diode corresponding to the light-blocking member 50 from entering the photosensitive sensor corresponding to the adjacent light-emitting diode, thereby improving the accuracy of brightness detection by the photosensitive sensor corresponding to the adjacent light-emitting diode. The second color resist 502 in the light-blocking member 50 is used to prevent light emitted by the adjacent light-emitting diode from entering the photosensitive sensor, thereby improving the accuracy of brightness detection by the photosensitive sensor corresponding to the light-blocking member 50. This improves the accuracy of brightness detection by each photosensitive sensor in the display panel 100, thereby enabling accurate compensation of the brightness of each light-emitting diode 20 in the display panel and improving the brightness uniformity of the display panel 20.

[0064] Example 4

[0065] This embodiment is the same as or similar to Embodiment 3, except that the position of the light-blocking component is further described.

[0066] In summary Figure 2 and Figure 3 As shown, in the same light-blocking component 50, the light-blocking component 50 is located on one side of a certain side of the photosensitive sensor 40. The first color resist 501 has the same color as the light emitted by its corresponding light-emitting diode 20. Preferably, the second color resist 502 has the same color as the light emitted by another light-emitting diode 20 adjacent to the light-emitting diode 20 on the same side as the light-blocking component 50. This will be explained in detail below.

[0067] In some embodiments, such as Figure 2As shown, the third color light-emitting diode 23, the first color light-emitting diode 21, and the second color light-emitting diode 22 are arranged adjacent to each other in sequence. The orthographic projection of the photosensitive sensor 40 corresponding to the first color light-emitting diode 21 on the driving substrate 10 is the first projection. The distance d1 from the first projection to the third color light-emitting diode 23 is less than the distance d2 from the first projection to the second color light-emitting diode 22. The light-blocking member 50 corresponding to the first color light-emitting diode 21 is at least disposed on the first side 101 of the corresponding photosensitive sensor 40. The first side is the side of the photosensitive sensor 40 corresponding to the first color light-emitting diode 21 that is close to the third color light-emitting diode 23.

[0068] In some embodiments, such as Figure 3 As shown, the third color light-emitting diode 23, the first color light-emitting diode 21, and the second color light-emitting diode 22 are arranged adjacent to each other in sequence. The orthographic projection of the photosensitive sensor 40 corresponding to the first color light-emitting diode 21 on the driving substrate 10 is the first projection. The distance d1 from the first projection to the third color light-emitting diode 23 is greater than the distance d2 from the first projection to the second color light-emitting diode 22. The light-blocking member 50 corresponding to the first color light-emitting diode 21 is at least disposed on the second side 102 of the corresponding photosensitive sensor 40. The second side 102 is the side of the photosensitive sensor 40 corresponding to the first color light-emitting diode 21 that is closer to the side of the second color light-emitting diode 22.

[0069] Example 5

[0070] This embodiment is the same as or similar to the above embodiment, except that the corresponding positions of the light-blocking member 50 and the sub-pixels of the light-emitting diode 20 are different.

[0071] exist Figure 1 , Figure 2 , Figure 3 The diagram illustrates that the photosensitive sensor 40 and the light-blocking member 50 in the same sensor group 60 are both positioned directly opposite the sub-pixels of their corresponding light-emitting diodes 20. That is, the orthogonal projection of the sub-pixel of the light-emitting diode 20 corresponding to the light-blocking member 50 on the driving substrate 10 covers the orthogonal projection of the light-blocking member 50 on the driving substrate 10.

[0072] In some embodiments, such as Figure 4 As shown, the light-blocking member 50 is disposed on the adjacent parts of the two sub-pixels corresponding to the two adjacent light-emitting diodes 20, the light-blocking member 50 is disposed on the sub-pixel of its corresponding light-emitting diode 20, and the light-blocking member 50 is disposed on the sub-pixel of another light-emitting diode 20 adjacent to its corresponding light-emitting diode 20.

[0073] In this embodiment, the occlusion of the center of the sub-pixels of the light-emitting diode 20 by the sensor group 60 can be reduced, thereby improving the display effect.

[0074] Example 6

[0075] This embodiment is the same as or similar to the above embodiment, except that the light-blocking component 50 also includes a third color filter.

[0076] In some embodiments, such as Figure 5 As shown, the light-blocking component 50 also includes a third color resist 503 disposed in parallel with the first color resist 501 and the second color resist 502 on the encapsulation cover plate 30. The third color resist 503 is one of the first color resist 51, the second color resist 52 and the third color resist 53, and the first color resist 501, the second color resist 502 and the third color resist 503 are different colors.

[0077] This simplifies the design of the color resist types in the light-blocking component 50.

[0078] Example 7

[0079] This embodiment is the same as or similar to the above embodiment, except that the light-blocking member 50 of the same sensor group 60 is arranged around the side of the photosensitive sensor 40.

[0080] In some embodiments, such as Figure 6 As shown, the light-blocking member 50 of the same sensor group 60 is arranged around the side of the photosensitive sensor 40.

[0081] Specifically, such as Figure 6 As shown, the light-blocking component 50 may include any one of the first color resist 51, the second color resist 52, and the third color resist 53, and the light-blocking components 50 of the same sensor group 60 are arranged around the side of the photosensitive sensor 40.

[0082] Specifically, such as Figure 6 As shown, the light-blocking component 50 may include any two of the first color resist 51, the second color resist 52, and the third color resist 53. The light-blocking components 50 of the same sensor group 60 are arranged around the side of the photosensitive sensor 40.

[0083] Specifically, such as Figure 6 As shown, the light-blocking component 50 may include three of the following: a first color resist 51, a second color resist 52, and a third color resist 53. The light-blocking components 50 of the same sensor group 60 are arranged around the side of the photosensitive sensor 40.

[0084] In some embodiments, in each sensor group 60, the height of the light-blocking member 50 on the encapsulation cover 30 is greater than the height of the photosensitive sensor 40 on the encapsulation cover 30.

[0085] It should be noted that in the display panel of any of the above embodiments, in each sensor group 60, the height of the light-blocking member 50 on the encapsulation cover plate 30 is greater than the height of the photosensitive sensor 40 on the encapsulation cover plate 30. The light-blocking member 50 can better block interfering light and improve the accuracy of the photosensitive sensor 40 in detecting brightness. Preferably, the height of the light-blocking member 50 on the encapsulation cover plate 30 is twice or more than twice the height of the photosensitive sensor 40 on the encapsulation cover plate 30, which can improve the blocking effect of the light-blocking member 50.

[0086] It should be noted that in any of the above embodiments, the light-blocking member 50 includes a color resist or uses a color resist in the display panel, which can absorb interfering light and reduce light crosstalk and light mixing problems between different sub-pixels or light-emitting diodes, reduce color crosstalk of the display panel, and will not affect the optical transmittance, thereby improving the display image quality of the display panel.

[0087] It should be noted that in some implementations of the above embodiments, the photosensitive sensor 40 is positioned directly opposite its corresponding light-emitting diode, which can improve the accuracy of the photosensitive sensor detection.

[0088] It should be noted that in the display panel of any of the above embodiments, in the same sensor group, the light-blocking member 50 can be arranged adjacent to the side of the photosensitive sensor 40 in contact with it; in the same sensor group, the light-blocking member 50 can also be arranged adjacent to the side of the photosensitive sensor 40 at a distance. In this case, it is preferable that the distance between the light-blocking member 50 and the photosensitive sensor 40 is less than or equal to 3 micrometers, which can improve the blocking effect of the light-blocking member 50.
