[0002] Organic Light Emitting Diodes (OLEDs) are active light-emitting display devices with advantages such as self-luminescence, wide viewing angles, high contrast, low power consumption, and extremely high response speed.

[0031] Please refer to Figure 1 , Figure 1 which is a schematic cross-sectional structure diagram of a display panel provided by an embodiment of the present application.

[0032] The display panel includes, from bottom to top, a substrate 101, a driving circuit layer 102, a light-emitting device layer 103, an encapsulation layer 104, a touch layer 105, a color filter layer 106, an optical adhesive layer 107, and a cover plate 108. The light-emitting device layer 103 includes a pixel definition layer (PDL) and a light-emitting device EL. The pixel definition layer (PDL) includes a pixel barrier D and a pixel opening. The light-emitting device EL is located within the pixel opening and includes an anode, a light-emitting layer, and a cathode. The driving circuit layer 102 includes a thin-film transistor T, the drain of which is connected to the anode. The color filter layer 106 includes a light-shielding portion 1061 and a light-filtering portion 1062. The light-filtering portion 1062 is located between adjacent light-shielding portions 1061 and corresponds to the light-emitting layer of the light-emitting device EL. The touch layer 105 is located between the encapsulation layer 104 and the light-shielding portion 1061.

[0033] The display panel may further include a sensor 109 located on the back of the substrate 101 . The sensor 109 may receive ambient light as well as light emitted by the display panel.

[0034] In the area corresponding to the sensor 109, the light shielding portion 1061 and the pixel retaining wall D are hollowed out to meet the basic light transmittance requirement of the sensor 109. However, how to increase the light transmittance of the sensor 109 area is still a key issue that needs to be studied and solved.

[0035] Based on this, an embodiment of the present application provides a display panel, including: a color filter layer, including a light-shielding portion and a light-filtering portion, the light-filtering portion being located between adjacent light-shielding portions; a metal routing layer, located on one side of the color filter layer and having a light-transmitting gap, the light-transmitting gap being arranged corresponding to the light-shielding portion; a first through-hole, penetrating the light-shielding portion along the thickness direction of the color filter layer, the metal routing in the metal routing layer being arranged around the first through-hole; a first opening, penetrating part of the light-shielding portion along the thickness direction and being arranged adjacent to the first through-hole, the first opening being arranged corresponding to the light-transmitting gap; a sensor, arranged on the side of the metal routing layer facing away from the color filter layer, and the orthographic projections of the first through-hole and the first opening on the sensor are both located within the sensor range.

[0036] In the embodiment of the present application, in the area corresponding to the sensor, not only is a first through hole penetrating the light-shielding portion provided, but also an opening is made on the light-shielding portion corresponding to the light-transmitting gap by utilizing the light-transmitting gap of the metal wiring layer to reduce the thickness of this part of the light-shielding portion, thereby increasing the light transmittance of the area.

[0037] The structure of the display panel provided in the embodiments of the present application is described below with reference to the accompanying drawings.

[0038] See also Figure 2 andFigure 3 , Figure 2 is a schematic diagram of a top view of a display panel provided in some embodiments of the present application, Figure 3 yes Figure 2 Schematic diagram of the cross-sectional structure of the first display area at B-B1.

[0039] The display panel 100 includes a color filter layer 10, a metal wiring layer 20, a first through-hole 31, a first opening 41, and a sensor S. The color filter layer 10 includes a light shielding portion 101 and a light filter portion 102, wherein the light filter portion 102 is located between adjacent light shielding portions 101. The metal wiring layer 20 is located on one side of the color filter layer 10 and has a light-transmitting gap 21, which is arranged corresponding to the light shielding portion 101. The first through-hole 31 penetrates the light shielding portion 101 along the thickness direction Z of the color filter layer 10, and the metal wiring in the metal wiring layer 20 is arranged around the first through-hole 31. The first opening 41 penetrates a portion of the light shielding portion 101 along the thickness direction Z and is arranged adjacent to the first through-hole 31. The first opening 41 is arranged corresponding to the light-transmitting gap 21. The sensor S is disposed on a side of the metal wiring layer 20 facing away from the color filter layer 10 , and the orthographic projections of the first through hole 31 and the first opening 41 on the sensor S are both located within the range of the sensor S.

[0040] The orthographic projections of the first through hole 31 and the first opening 41 on the sensor S are both located within the range of the sensor S, thereby ensuring that light can pass through the first through hole 31 and the first opening 41 to reach the sensor S.

[0041] In some embodiments, the sensor S may include at least one of an ambient light sensor, a touch screen sensor, and an infrared sensor. The ambient light sensor is specifically used to detect the intensity of external light, helping the device automatically adjust the brightness of the display screen based on changes in ambient light to improve visibility and energy saving. Touch screen sensors are used in certain touch screen technologies (such as optical touch screens) and can receive external light or light emitted by the display screen to detect touch locations. Infrared sensors can be used for facial recognition or gesture control and can receive infrared light from the outside or emitted by the device.

[0042] like Figure 2 As shown, the display panel 100 may include a first display area A1 and a second display area A2, wherein the second display area A2 is disposed adjacent to the first display area A1. In some embodiments, the second display area A2 may be disposed around the first display area A1. The sensor S is located in the first display area A1, and the first through-hole 31 and the first opening 41 are both located in the first display area A1.

[0043] The top view shape of the first display area A1 can be set according to actual needs, such as oval, circular or rectangular, and the present application does not limit this.

[0044] It can be understood that both the first display area A1 and the second display area A2 can achieve the display function. The difference is that the first display area A1 is provided with a sensor S. Therefore, the first display area A1 can not only undertake the general display function, but also allow light to pass through. Thus, the first display area A1 can also be called the sensor area A1. The first through hole 31 and the first opening 41 are located in the sensor area A1 to increase the light transmittance of the sensor area A1. Among them, the color filter layer 10 and the metal trace layer 20 are both located in the first display area A1 and the second display area A2.

[0045] In some embodiments, the light-shielding portion 101 includes a light-shielding area 101a, a fully transparent area 101b, and a semi-transparent area 101c. The first through hole 31 is located in the fully transparent area 101b, the first opening 41 is located in the semi-transparent area 101c, and the light-shielding area 101a does not have the first through hole 31 and the first opening 41. Since the first opening 41 thins the thickness of the light-shielding portion 101, the thickness of the light-shielding portion 101 in the light-shielding area 101a is greater than the thickness of the light-shielding portion 101 in the semi-transparent area 101c. It should be noted that the thickness of the light-shielding portion 101 in the fully transparent area 101b can be understood as 0 because the light-shielding portion 101 in the fully transparent area 101b is completely hollowed out.

[0046] It can be understood that the difference between the first through hole 31 and the first opening 41 is that the first through hole 31 completely penetrates the light-shielding portion 101, while the first opening 41 only penetrates part of the light-shielding portion 101. Since the first through hole 31 completely opens the light-shielding portion 101, and the first opening 41 only opens part of the light-shielding portion 101, the light transmittance of the light-shielding area 101a is less than the light transmittance of the semi-transparent area 101c, and the light transmittance of the semi-transparent area 101c is less than the light transmittance of the fully transparent area 101b.

[0047] In some embodiments, the first opening 41 in the light-shielding portion 101 in the semi-transparent area 101c can be formed by using a photolithography process and an etching process. Since the top size of the first opening 41 is very small, in the developing step of the photolithography process, the photoresist cannot be completely developed, so that this part of the light-shielding portion 101 cannot be completely etched open (that is, the part of the light-shielding portion 101 penetrated by the first opening 41), but the thickness of this part of the light-shielding portion 101 is reduced, so the light transmittance of the semi-transparent area 101c can be increased.

[0048] Since the top size of the first opening 41 is very small and it becomes more difficult to etch as it goes downwards, in the thickness direction Z along the direction close to the sensor S (i.e., from top to bottom), the size CD of the first opening 41 in the first direction X gradually decreases. The first direction X is perpendicular to the thickness direction Z. Therefore, the top size of the first opening 41 is the largest.

[0049] In some embodiments, the maximum size CD (i.e., the top size) of the first opening 41 in the first direction X is 0.1 micrometer to 2 micrometers.

[0050] In some embodiments, since the color film layer 10 exists in both the first display area A1 and the second display area A2, and the light-shielding portion 101 in the second display area A2 is light-impermeable, the light-shielding area 101a of the light-shielding portion 101 can be located in the second display area A2.

[0051] In other embodiments, as Figure 3 shown, there can also be a light-shielding portion 101 in the first display area A1 that is not perforated and not open. Therefore, the light-shielding area 101a of the light-shielding portion 101 can also be located in the first display area A1.

[0052] Please refer to Figure 4 , Figure 4 which Figure 2 is a top view structural schematic diagram of the first opening and the first through hole in the first display area in Figure 4 Shown are the actually observed first opening 41 and the first through hole 31. White represents light transmission and black represents light impermeability. Among them, the white spots are the positions where the first opening 41 is located, and the white rectangles are the positions where the first through hole 31 is located.

[0053] In some embodiments, the metal wiring layer 20 includes a driving wiring layer 20a and a touch control wiring layer 20b. The driving wiring layer 20a has a first wiring gap 21a. The touch control wiring layer 20b is located between the driving wiring layer 20a and the light-shielding portion 101, and the touch control wiring layer 20b has a second wiring gap 21b. Among them, the light transmission gap 21 of the metal wiring layer 20 is the gap where the first wiring gap 21a and the second wiring gap 21b overlap.

[0054] It can be understood that the light transmission gap 21 means that light can pass through the metal wiring layer 20 from the light transmission gap 21. That is to say, light can pass through both the first wiring gap 21a and the second wiring gap 21b at the same time, indicating that the position of the first opening 41 (white spots) corresponds to the overlapping part of the first wiring gap 21a and the second wiring gap 21b, that is, the light transmission gap 21.

[0055] Since the light shielding portion 101 corresponding to the light-transmitting gap 21 is provided with the first opening 41 , the light transmittance of this portion is increased, thereby improving the overall light transmittance of the first display area A1 .

[0056] In order to improve the transmittance of the first through hole 31, the wiring in the metal wiring layer 20 will bypass the first through hole 31. However, no matter how densely the wiring in the metal wiring layer 20 is arranged outside the first through hole 31, there will always be wiring gaps, and thus light-transmitting gaps 21.

[0057] In some embodiments, a plurality of first through holes 31 may be provided in the first display area A1, and a first opening 41 may be provided on each light shielding portion 101 corresponding to each light-transmitting gap 21 in the first display area A1. Opening the light shielding portion 101 above each light-transmitting gap 21 not only improves light transmittance but also simplifies the etching process.

[0058] Since the provision of the first through hole 31 causes the reflectivity of the first display area A1 to be greater than the reflectivity of the second display area A2, a visual difference between the second display area A2 and the first display area A1 is caused when the screen is off.

[0059] In some embodiments, the surface of the first opening 41 that contacts the light shielding portion 101 is a curved surface, and the roughness of the curved surface is greater than the roughness of the surface of the light shielding portion 101a in the light shielding area 101. In other words, the roughness of the curved surface is greater than the roughness of the surface of the light shielding portion 101 that is not open and has no holes.

[0060] Since the shading portion 101 of the second display area A2 is not perforated and has no opening, that is, the second display area A2 includes the shading area 101a, and the arc surface where the first opening 41 contacts the shading portion 101 is located in the first display area A1, the roughness of the arc surface in the first display area A1 is greater than the roughness of the surface of the shading portion 101 in the second display area A2. This can increase the diffuse reflection of the first display area A1, thereby improving the reflectivity of the first display area A1, so as to reduce the reflectivity difference between the first display area A1 and the second display area A2, and further reduce the visual difference between the first display area A1 and the second display area A2 in the screen-off state.

[0061] The display panel 100 may further include a pixel definition layer 50 and a light-emitting layer 60. The pixel definition layer 50 is located between the drive wiring layer 20a and the color filter layer 10. The pixel definition layer 50 includes pixel retaining walls D and pixel openings, and the pixel openings are located between adjacent pixel retaining walls D. The light-emitting layer 60 is located within the pixel openings. The light filter 102 is provided corresponding to the light-emitting layer 60, and the light shielding portion 101 is provided corresponding to the pixel retaining walls D.

[0062] The display panel may further include a packaging layer 70 located between the pixel defining layer 50 and the color filter layer 10.

[0063] In some embodiments, the light-emitting layer 60 may include a red light-emitting layer, a blue light-emitting layer, and a green light-emitting layer, and the light filtering portion 102 may include a red color resistor, a blue color resistor, and a green color resistor. Among them, the red color resistor is disposed corresponding to the red light-emitting layer, the blue color resistor is disposed corresponding to the blue light-emitting layer, and the green color resistor is disposed corresponding to the green light-emitting layer.

[0064] The pixel barrier D may be made of a light-impermeable material to reduce color crosstalk between adjacent light-emitting layers 60. In some embodiments, the display panel 100 may include a second through hole 32 that penetrates the pixel barrier D along the thickness direction Z of the pixel defining layer 50. Among them, the orthographic projection of the first through hole 31 on the sensor S is within the range of the orthographic projection of the second through hole 32 on the sensor S, thereby improving the light transmittance of the first display area A1.

[0065] In some embodiments, the display panel 100 may further include a second opening 42 that penetrates part of the pixel defining layer 50 along the thickness direction Z. Among them, the orthographic projection of the second opening 42 on the sensor S overlaps with the orthographic projection of the first opening 41 on the sensor S.

[0066] Since the second opening 42 thins the thickness of the pixel barrier D, the light transmittance of the first display area A1 can be improved, enabling the sensor S to receive more light.

[0067] Please refer to Figure 5 , Figure 5 which is a top view structural schematic diagram of the color filter layer provided by some embodiments of the present application.

[0068] In some embodiments, an opening 101d is formed between the light-shielding portions 101, the light filtering portion 102 is located within the opening 101d and covers part of the light-shielding portion 101, and adjacent light filtering portions 102 are spaced apart.

[0069] Please refer to Figure 6 , Figure 6 which is a top view structural schematic diagram of the color filter layer provided by some embodiments of the present application.

[0070] The difference between this embodiment and Figure 5 the embodiment is that the light filtering portion 102 not only is located within the opening 101d, but also covers the surface of the light-shielding portion 101, and adjacent light filtering portions 102 are connected to each other or overlap each other.

[0071] Please continue to refer to Figure 3 , the display panel 100 further includes a third through hole 33 that penetrates the light filtering portion 102 along the thickness direction Z. Wherein, the third through hole 33 communicates with the first through hole 31 along the thickness direction Z, so that light can sequentially pass through the third through hole 33, the first through hole 31, and the second through hole 32 to reach the sensor S, and this can reduce the influence of the light filtering portion 102 on the light transmittance.

[0072] In some embodiments, the display panel 100 further includes a third opening 43 that penetrates a part of the light filtering portion 102 along the thickness direction Z. Wherein, the orthographic projection of the third opening 43 on the sensor S overlaps with the orthographic projection of the first opening 41 on the sensor S. Therefore, the first opening 41, the second opening 42, and the third opening 43 are all correspondingly arranged with the light transmission gap 21 to increase the light transmittance of the first display area A1.

[0073] In some embodiments, the light emitting layer 60 can not only be located in the second display area A2, but also in the first display area A1, and a light emitting layer 60 can also be arranged between the first through hole 31 and the first opening 41. The position of the first opening 41 is completely determined by the light transmission gap 21.

[0074] Please refer to Figure 7 , Figure 7 which is a schematic cross-sectional structure diagram of a display panel provided by some embodiments of the present application. The difference between this embodiment and Figure 3 the embodiment lies in the structure between the first through hole 31 and the first opening 41.

[0075] As Figure 7 shown, although the light emitting layer 60 is located in the second display area A2 and the first display area A1, there is at least one first through hole 31 where there is no light emitting layer 60 between the first through hole 31 and the first opening 41, that is, the light shielding portion 101 penetrated by the first through hole 31 and the light shielding portion 101 penetrated by the first opening 41 are continuous.

[0076] An embodiment of the present application further provides a display device, including the display panel 100 in any of the above embodiments. This display device has the same beneficial effects as the above display panel 100, and will not be elaborated here.

[0077] The description of the above embodiments is only used to help understand the technical solution and its core idea of the present application; those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
