Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to an OLED display screen, an OLED display screen assembly and an electronic device. Background Art

[0002] The setting of the under-screen optical device is conducive to improving the screen-to-body ratio of the display screen while realizing functions such as front-facing shooting, fingerprint recognition, ambient light detection, proximity light detection, and face recognition. However, in the related art, in order to reduce the reflection of external ambient light, a technical solution of physically blocking the external ambient light is adopted, which leads to the technical problem that the under-screen optical device cannot receive external light or the appearance of the under-screen optical device is visible. Summary of the invention

[0003] The present application provides an OLED display screen, an OLED display screen assembly, and an electronic device that are conducive to hiding under-screen optical devices.

[0004] In one aspect, the present application provides an OLED display screen, comprising:

[0005] An OLED light-emitting panel, the OLED light-emitting panel comprising a plurality of pixel units, each of the pixel units comprising a plurality of sub-pixels arranged at intervals; and

[0006] A color filter layer, wherein the color filter layer covers the light-emitting side of the OLED light-emitting panel, the color filter layer includes a plurality of filter units, each of the filter units includes a plurality of filter parts arranged at intervals and at least one first shading part, each of the filter parts covers a corresponding sub-pixel, the first shading part is located between two adjacent filter parts, and at least one of the first shading parts of each filter unit has a first light-through hole.

[0007] On the other hand, the present application also provides an OLED display assembly, comprising at least one optical device and the OLED display, wherein the optical device is located on the side of the OLED light-emitting panel away from the color film layer, and the optical device is arranged corresponding to the plurality of the first light holes.

[0008] On the other hand, the present application also provides an electronic device, including a housing and the OLED display assembly, wherein a receiving space is formed between the housing and the OLED display, and the optical device is located in the receiving space.

[0009] The OLED display provided by the present application includes an OLED light-emitting panel and a color filter layer. Since the OLED light-emitting panel includes multiple pixel units, each pixel unit includes multiple sub-pixels arranged at intervals, the color filter layer covers the light-emitting side of the OLED light-emitting panel, and the color filter layer includes multiple filter units, each filter unit includes multiple filter parts arranged at intervals and at least one first shading part, each filter part covers a sub-pixel correspondingly, and the first shading part is located between two adjacent filter parts. The light emitted by the sub-pixel can be transmitted through the filter part to form a display image, and the shading effect of the first shading part can reduce the external ambient light from entering the OLED display and reflecting, thereby improving the contrast of the OLED display and improving the use effect of the OLED display under strong light. Compared with the solution using a polarizer, the transmittance of the color filter layer in this solution can be higher and the color filter layer can be thinner, which is conducive to improving the brightness of the display image and is suitable for a thin and light design of the OLED display. In addition, at least one first light-shielding portion of each filter unit has a first light-through hole, that is, all the filter units in the entire color film layer have a first light-through hole. This can not only realize the design of the optical device under the screen, but also make the reflectivity and light transmittance of the entire screen uniform, thereby hiding the position of the optical device under the screen and making it difficult for the user to see the optical device under the screen.

DETAILED DESCRIPTION

[0048] The technical solution provided by the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, not all of the embodiments. Based on the embodiments described in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0049] References to "embodiments" and "implementations" in this application mean that the specific features, structures, or characteristics described in conjunction with the embodiments or implementations may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It can be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0050] The terms "first", "second", etc. in the specification and claims of this application and the above drawings are used to distinguish different objects rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions.

[0051] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic plan view of an OLED display screen 100 provided in an embodiment of the present application, Figure 2A cross-sectional schematic diagram of an OLED display screen 100 provided in an embodiment of the present application. The cross-sectional schematic diagram of the OLED display screen 100 can be understood as a cross-sectional schematic diagram along the thickness direction of the OLED display screen 100. The thickness direction of the OLED display screen 100 can refer to the Z-axis direction of the accompanying drawing. OLED (Organic Light Emitting Diode) is also called an organic light-emitting semiconductor. The OLED display screen 100 is used to display information such as text, images, and videos. In the embodiment of the present application, a rectangular OLED display screen 100 is taken as an example. It should be noted that the shape of the OLED display screen 100 includes but is not limited to a rectangle. For example, the shape of the OLED display screen 100 can also be square, circular, etc. The OLED display screen 100 includes an OLED light-emitting panel 10 and a color film layer 20 covering the light-emitting side of the OLED light-emitting panel 10. It can be understood that the OLED light-emitting panel 10 emits light at least toward the side where the color film layer 20 is located. Among them, an adhesive layer, other optical functional layers, etc. can also be set between the OLED light-emitting panel 10 and the color film layer 20, which are not illustrated in the accompanying drawings of the present application.

[0052] like Figure 3 As shown, Figure 3 for Figure 2 A schematic cross-sectional view of an OLED light-emitting panel 10 in the OLED display screen 100 shown. The OLED light-emitting panel 10 is used to emit light. The OLED light-emitting panel 10 may include an anode 11, an organic light-emitting layer 12, a cathode 13 and a substrate 14 stacked in sequence; or, the OLED light-emitting panel 10 may also include a hole transport layer 15 between the anode 11 and the organic light-emitting layer 12, and / or, include an electron transport layer 16 between the organic light-emitting layer 12 and the cathode 13; or, the OLED light-emitting panel 10 may also include a hole injection layer 17 between the anode 11 and the hole transport layer 15, and / or, include an electron injection layer 18 between the electron transport layer 16 and the cathode 13; or, the OLED light-emitting panel 10 may also include an electron blocking layer 19 between the hole transport layer 15 and the organic light-emitting layer 12, and / or, include a hole blocking layer 21 between the organic light-emitting layer 12 and the electron transport layer 16.

[0053] Among them, the substrate is the basis of the entire OLED light-emitting panel 10 and is used to carry other functional layers. The material of the substrate can be glass, plastic, etc. The anode 11 is connected to the positive electrode of the external driving voltage of the OLED light-emitting panel 10. The holes in the anode 11 can move to the light-emitting layer of the OLED light-emitting panel 10 under the drive of the external driving voltage. Generally speaking, the anode 11 needs to have a certain light transmittance so that the light emitted by the organic light-emitting layer 12 can be emitted. The material of the anode 11 can be ITO. The hole injection layer 17 can drive the holes from the anode 11 to be smoothly injected into the hole transport layer 15. The hole transport layer 15 is responsible for transporting the holes to the light-emitting layer. The electron blocking layer 19 can block the electrons from the cathode 13 at the interface of the organic light-emitting layer 12 of the OLED light-emitting panel 10, and increase the electron concentration at the interface of the organic light-emitting layer 12 of the OLED light-emitting panel 10. The organic light-emitting layer 12 is the position where the electrons and holes in the OLED light-emitting panel 10 recombine to form excitons, and the excitons de-excite to emit light. The hole blocking layer 21 blocks the holes from the anode 11 at the interface of the organic light-emitting layer 12 of the OLED light-emitting panel 10, thereby increasing the probability of electrons and holes being recombined at the interface of the organic light-emitting layer 12 of the OLED light-emitting panel 10, and increasing the luminous efficiency of the OLED light-emitting panel 10. The electron transport layer 16 is responsible for transferring electrons from the cathode 13 to the organic light-emitting layer 12. The electron injection layer 18 serves to modify the cathode 13 and transfer electrons to the electron transport layer 16. The cathode 13 is connected to the negative electrode of the external driving voltage of the OLED light-emitting panel 10. The electrons in the cathode 13 will move to the organic light-emitting layer 12 under the drive of the external driving voltage of the OLED light-emitting panel 10, and then recombine with the holes from the anode 11 in the organic light-emitting layer 12.

[0054] like Figure 4 As shown, Figure 4 for Figure 2 A cross-sectional schematic diagram of the color filter layer 20 of the OLED display screen 100 is shown covering the light-emitting side of the OLED light-emitting panel 10. In the present application, the color filter layer 20 can be located on the side of the anode 11 of the OLED light-emitting panel 10 away from the organic light-emitting layer 12. The light from the OLED light-emitting panel 10 that enters the color filter layer 20 is emitted through the side of the color filter layer 20 that is away from the OLED light-emitting panel 10 to form a display screen of the OLED display screen 100.

[0055] like Figure 5 As shown, Figure 5 for Figure 2A schematic diagram of a planar structure of an OLED light-emitting panel 10 in an OLED display screen 100 is shown. The OLED light-emitting panel 10 includes a plurality of pixel units 101. Each pixel unit 101 includes a plurality of sub-pixels 110 arranged at intervals. The present application does not specifically limit the number of pixel units 101 and the number of sub-pixels 110 in each pixel unit 101. For example: the number of pixel units 101 can be one hundred thousand, one million, ten million, one hundred million, one billion, etc. The number of pixel units 101 in the drawings of the present application is only for illustration and should not be understood as a limitation on the number of pixel units 101. The number of sub-pixels 110 in each pixel unit 101 can be two, three, four, five, etc. Different sub-pixels 110 in each pixel unit 101 can emit light of different colors.

[0056] like Figure 6 As shown, Figure 6 for Figure 2 A schematic diagram of a planar structure of the color filter layer 20 in the OLED display screen 100 is shown. The color filter layer 20 includes a plurality of filter units 201. Each filter unit 201 includes a plurality of filter parts 210 arranged at intervals and at least one first light shielding part 211 located between two adjacent filter parts 210. The present application does not specifically limit the number of filter units 201, the number of filter parts 210 in each filter unit 201, and the number of first light shielding parts 211. For example, the number of filter units 201 can be one hundred thousand, one million, ten million, one hundred million, one billion, etc. The number of filter units 201 in the drawings of the present application is only for illustration and should not be understood as limiting the number of filter units 201. The number of filter parts 210 in each filter unit 201 can be two, three, four, five, etc. The number of first light shielding parts 211 in each filter unit 201 can be one, two, three, four, etc. Among them, the number of filter units 201 and the number of pixel units 101 can be the same. The number of the filter sections 210 in each filter unit 201 may be the same as the number of the sub-pixels 110 in each pixel unit 101. The number of the first light shielding sections 211 in each filter unit 201 is less than the number of the filter sections 210. It can be understood that the number of the first light shielding sections 211 may be the number of the filter sections 210 minus N, where N is an integer greater than or equal to 1 and less than the number of the filter sections 210.

[0057] Please refer to Figures 5 to 7, the filter section 210 may include a color filter (CF). The filter section 210 is used to transmit light of a specific wavelength band. Each filter section 210 covers a corresponding sub-pixel 110. In the present application, the filter section 210 can transmit the light emitted by the corresponding sub-pixel 110, and can block the light emitted by other sub-pixels 110 from passing through. The first light shielding section 211 is located between two adjacent filter sections 210. Specifically, the first light shielding section 211 connects two adjacent filter sections 210. In other words, one side of the first light shielding section 211 is directly adjacent to one filter section 210, and the other side of the first light shielding section 211 is directly adjacent to another adjacent filter section 210. The first light shielding section 211 may include a black matrix (BM). The first light shielding section 211 is opaque. In a possible application scenario, the first light shielding section 211 is used to block external ambient light from entering the interior of the OLED display screen 100 through the space between two adjacent filter sections 210. In addition, the first light shielding portion 211 is located between two adjacent light filtering portions 210, which can also prevent the light between the two adjacent light filtering portions 210 from mixing or color cross-talk. At least one first light shielding portion 211 of each light filtering unit 201 has a first light through hole 2110. It can be understood that when each light filtering unit 201 includes one first light shielding portion 211, the first light shielding portion 211 of each light filtering unit 201 has a first light through hole 2110. When each light filtering unit 201 includes two or more first light shielding portions 211, part of the first light shielding portions 211 of each light filtering unit 201 may have a first light through hole 2110, and another part of the first light shielding portions 211 may not be provided with the first light through hole 2110; or, all the first light shielding portions 211 of each light filtering unit 201 have a first light through hole 2110. Among them, the design of the first shading portion 211 can reduce the reflectivity of the OLED display 100 to avoid glare, and the design of the first light hole 2110 is conducive to the design of the optical device under the screen, that is, the optical device under the screen can receive and / or emit light through the first light hole 2110 to achieve corresponding optical functions.

[0058] The OLED display screen 100 provided in the present application includes an OLED light-emitting panel 10 and a color filter layer 20. Since the OLED light-emitting panel 10 includes a plurality of pixel units 101, each pixel unit 101 includes a plurality of sub-pixels 110 arranged at intervals, the color filter layer 20 covers the light-emitting side of the OLED light-emitting panel 10, and the color filter layer 20 includes a plurality of filter units 201. Each filter unit 201 includes a plurality of filter portions 210 arranged at intervals and at least one first light shielding portion 211. Each filter portion 210 covers a sub-pixel 110 correspondingly, and the first light shielding portion 211 is located between two adjacent filter portions. 210, the light emitted by the sub-pixel 110 can be transmitted through the light filtering function of the light filtering part 210 to form a display screen, and the light shielding function of the first light shielding part 211 can reduce the external ambient light from entering the OLED display screen 100 and causing reflection, thereby improving the contrast of the OLED display screen 100 and improving the use effect of the OLED display screen 100 under strong light. Compared with the solution using a polarizer, the color filter layer 20 in this solution can have a higher transmittance and be thinner, which is conducive to improving the brightness of the display screen and being suitable for the thin and light design of the OLED display screen 100. In addition, at least one first light shielding part 211 of each light filtering unit 201 has a first light through hole 2110, that is, the light filtering units 201 of the entire layer of the color filter layer 20 all have the first light through hole 2110, so that the design of the optical device under the screen can be realized, and the reflectivity and light transmittance of the entire screen can be made uniform, so that the position of the optical device under the screen can be hidden, so that the optical device under the screen is not easily seen by the user.

[0059] In one possible embodiment, please refer to Figures 8 to 10 , each pixel unit 101 includes a first sub-pixel 111, a second sub-pixel 112, and a third sub-pixel 113 arranged in sequence. In the embodiment of the present application, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 are arranged in sequence along the width direction of the OLED display screen 100 as an example. Of course, in other embodiments, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 can be arranged in sequence along the length, diagonal direction, etc. of the OLED display screen 100. Among them, the width direction of the OLED display screen 100 can refer to the X-axis direction of the accompanying drawings; the length direction of the OLED display screen 100 can refer to the Y-axis direction of the accompanying drawings.

[0060] Among them, the first sub-pixel 111 is used to emit light of a first color, the second sub-pixel 112 is used to emit light of a second color, and the third sub-pixel 113 is used to emit light of a third color. In a possible implementation, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 can be used to emit red (R), green (G), and blue (B) light, that is, the first color is red (R), the second color is green (G), and the third color is blue (B). Of course, in other implementations, the first color can be blue (B), the second color can be green (G), and the third color can be red (R); or, the first color can be green (G), the second color can be blue (B), and the third color can be red (R), etc. In another possible implementation, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 can also be used to emit cyan (C), magenta (M), and yellow (Y) light, that is, the first color is cyan, the second color is magenta, and the third color is yellow. In the following embodiments, unless otherwise specified, the first sub-pixel 111 is used to emit red (R) light, the second sub-pixel 112 is used to emit green (G) light, and the third sub-pixel 113 is used to emit blue (B) light. That is, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 form an RGB pixel unit 101.

[0061] Each filter unit 201 includes a first filter section 212, a second filter section 213, and a third filter section 214 arranged in sequence. In the embodiment of the present application, the first filter section 212, the second filter section 213, and the third filter section 214 are arranged in sequence along the width direction of the OLED display screen 100 as an example. The first filter section 212 covers the first sub-pixel 111, and the first filter section 212 is used to transmit the light of the first color and to block the light of other colors from passing through. It can be understood that the first filter section 212 is arranged on the light-emitting side of the first sub-pixel 111 along the thickness direction of the OLED display screen 100. In the embodiment of the present application, the first filter section 212 can transmit red (R) light and can block green (G) light and blue (B) light. The second filter section 213 covers the second sub-pixel 112, and the second filter section 213 is used to transmit the light of the second color and to block the light of other colors from passing through. It is understandable that the second filter section 213 is arranged on the light-emitting side of the second sub-pixel 112 along the thickness direction of the OLED display screen 100. In the embodiment of the present application, the second filter section 213 can transmit green (G) light, and can block red (R) light and blue (B) light. The third filter section 214 covers the third sub-pixel 113, and the third filter section 214 is used to transmit light of the third color and to block light of other colors from transmitting. It is understandable that the third filter section 214 is arranged on the light-emitting side of the third sub-pixel 113 along the thickness direction of the OLED display screen 100. In the embodiment of the present application, the third filter section 214 can transmit blue (B) light, and can block green (G) light and red (R) light.

[0062] By making the number of filter parts 210 correspond to the number of sub-pixels 110, and the corresponding filter part 210 only transmits the light emitted by the corresponding sub-pixel 110, the display of color images can be realized, and the light of the three primary colors can be mixed to realize the display of various colors, enriching the display color of the OLED display screen 100. In addition, the setting of the first filter part 212 can also prevent the light of non-first color in the external ambient light from entering the OLED display screen 100 and being reflected. The setting of the second filter part 213 can also prevent the light of non-second color in the external ambient light from entering the OLED display screen 100 and being reflected. Similarly, the setting of the third filter part 214 can also prevent the light of non-third color in the external ambient light from entering the OLED display screen 100 and being emitted. Therefore, the reflectivity of the OLED display screen 100 can be reduced, the contrast and display effect of the OLED display screen 100 under ambient light can be improved, and the OLED display screen 100 can be prevented from causing dazzle to the user.

[0090] In the following embodiments, the fifth sub-pixel 115 emitting green (G) light is taken as an example unless otherwise specified. The fifth sub-pixel 115 emitting the fifth color light may refer to the embodiment in which the fifth sub-pixel 115 emits the fifth color light.

[0091] By making two adjacent pixel units 101 share a fifth sub-pixel 115 , the color difference of the display area corresponding to the two adjacent pixel units 101 can be reduced, and the clarity and fineness of the display image of the OLED display screen 100 can be improved.

[0092] The area of ​​the second sub-pixel 112 may be smaller than or equal to the area of ​​the first sub-pixel 111. The area of ​​the third sub-pixel 113 may be equal to the area of ​​the first sub-pixel 111. The area of ​​the fifth sub-pixel 115 may be smaller than or equal to the area of ​​the first sub-pixel 111. In a possible implementation, the area of ​​the first sub-pixel 111 may be the same as the area of ​​the third sub-pixel 113, and the area of ​​the second sub-pixel 112 may be the same as the area of ​​the fifth sub-pixel 115.

[0093] The first sub-pixel 111 and the third sub-pixel 113 are adjacent and spaced along the first direction. The second sub-pixel 112 and the fifth sub-pixel 115 are adjacent and spaced along the second direction. The second direction intersects with the first direction. In the embodiment of the present application, the first direction is the length direction of the OLED display screen 100, the second direction is the width direction of the OLED display screen 100, and the first direction is perpendicular to the second direction. Of course, in other embodiments, the first direction and the second direction may intersect but not be perpendicular.

[0094] Each filter unit 201 includes two first light shielding parts 211, one first light shielding part 211 is located between the first light filter part 212 and the third light filter part 214, and the other first light shielding part 211 is located between the second light filter part 213 and the fifth light filter part 216, and the first light shielding part 211 located between the first light filter part 212 and the third light filter part 214 and the first light shielding part 211 located between the second light filter part 213 and the fifth light filter part 216 form an overlapping area, and the overlapping area has a first light through hole 2110. It can be understood that one first light shielding part 211 connects the first light filter part 212 and the third light filter part 214 along the first direction, and the other first light shielding part 211 connects the second light filter part 213 and the fifth light filter part 216 along the second direction. In other words, one side of a first light shielding portion 211 is directly adjacent to the first light filtering portion 212 along the first direction, and the other side is directly adjacent to the third light filtering portion 214 along the first direction; one side of another first light shielding portion 211 is directly adjacent to the second light filtering portion 213 along the second direction, and the other side is directly adjacent to the fifth light filtering portion 216 along the first direction. The first light through hole 2110 can be located at the center of the overlapping area, or can be eccentrically arranged.

[0095] The first light shielding portion 211 between the first light filter portion 212 and the third light filter portion 214 can prevent external ambient light from entering the OLED display screen 100 through the space between the first light filter portion 212 and the third light filter portion 214 and causing reflection, and can prevent light from mixing or crossing colors between the first light filter portion 212 and the third light filter portion 214. The first light shielding portion 211 between the second light filter portion 213 and the fifth light filter portion 216 can prevent external ambient light from entering the OLED display screen 100 through the space between the second light filter portion 213 and the fifth light filter portion 216 and causing reflection, thereby avoiding glare to the user.

[0096] The first light holes 2110 in the overlapping area of ​​the two first light shielding parts 211 are conducive to the under-screen optical device 22 receiving and / or emitting light through the corresponding first light holes 2110, so as to realize the design of the under-screen optical device 22. In addition, the first light holes 2110 of the entire OLED display screen 100 are evenly distributed, so that the reflectivity and transmittance of each area of ​​the OLED display screen 100 are more uniform, which can realize the hiding of the under-screen optical device 22 and improve the display uniformity of the display screen.

[0097] Optionally, the diameter of the first light hole 2110 may be 10 μm to 25 μm. For example, the diameter of the first light hole 2110 may be 10 μm, or the diameter of the first light hole 2110 may be 12 μm, or the diameter of the first light hole 2110 may be 17 μm, or the diameter of the first light hole 2110 may be 25 μm, etc.

[0098] For further information, please refer to Fig.29 and Fig.30 The color filter layer 20 further includes a plurality of second light shielding portions 202, each of which is located between two adjacent filter units 201. The plurality of second light shielding portions 202 have second light through holes 220. In one possible implementation, each second light shielding portion 202 of the color filter layer 20 has a second light through hole 220. In another possible implementation, some of the second light shielding portions 202 of the color filter layer 20 may have a second light through hole 220, and another portion of the second light shielding portions 202 may not have a second light through hole 220. For example: two second light shielding parts 202 are arranged between three adjacent filter units 201, one second light shielding part 202 has a second light through hole 220, and the other second light shielding part 202 does not have a second light through hole 220; or, the second light shielding part 202 between two filter units 201 arranged along the first direction has a second light through hole 220, and the second light shielding part 202 between two filter units 201 arranged along the second direction does not have a second light through hole 220, etc. Among them, the design of the second light through hole 220 is also conducive to the under-screen optical device 22 receiving and / or emitting light through the second light through hole 220. In the embodiment in which each second light shielding part 202 of the color filter layer 20 has a second light through hole 220, the reflectivity and transmittance of the OLED display screen 100 are more uniform, which is more conducive to hiding the under-screen optical device 22.

[0099] Optionally, the diameter of the second light hole 220 may be 10 μm to 25 μm. For example, the diameter of the second light hole 220 may be 10 μm; or, the diameter of the second light hole 220 may be 12 μm; or, the diameter of the second light hole 220 may be 17 μm; or, the diameter of the second light hole 220 may be 25 μm, etc. The diameter of the second light hole 220 may be the same as or different from the diameter of the first light hole 2110.

[0100] Furthermore, if Fig.31 As shown, the OLED display screen 100 also includes an anti-reflection protective layer 30 covering the side of the color filter layer 20 away from the OLED light-emitting panel 10, and the anti-reflection protective layer 30 is used to reduce the reflectivity of the OLED display screen 100. The anti-reflection protective layer 30 can be an anti-reflection (AR) film, an AR coating, etc. In the present application, by setting a first light-through hole 2110 in the first light-shielding portion 211 of each filter unit 201, the light acquisition of the optical device 22 under the screen can be achieved, and the reflectivity and transmittance of the whole screen are more uniform, but since the opening also increases the reflectivity of the OLED display screen 100, the anti-reflection protective layer 30 is covered on the side of the color filter layer 20 away from the OLED light-emitting panel 10, the reflectivity of the OLED display screen 100 can be reduced, and the display effect of the OLED display screen 100 under ambient light can be ensured.

[0101] Furthermore, if Fig.32 As shown, the OLED display screen 100 also includes a structural reinforcement layer 40 supported on the side of the OLED light-emitting panel 10 away from the color film layer 20, and the structural reinforcement layer 40 is used to increase the structural strength of the OLED display screen 100. The structural reinforcement layer 40 may include one or more support plates, one or more support columns, one or more reinforcing ribs, etc. In the present application, by setting a first light-through hole 2110 in the first light-shielding portion 211 of each filter unit 201, light acquisition of the optical device 22 under the screen can be achieved, and the reflectivity and transmittance of the entire screen are more uniform, but the opening also reduces the strength of the OLED display screen 100. Therefore, by setting a structural reinforcement layer 40 on the side of the OLED light-emitting panel 10 away from the color film layer 20, the structural strength of the OLED display screen 100 can be increased.

[0102] In addition, if Fig.33 As shown, the present application also provides an OLED display assembly 200. The OLED display assembly 200 includes at least one optical device 22 and the OLED display 100 described in any of the above embodiments.

For example, the light sensor may be an ambient light sensor, an infrared light sensor, a sunlight sensor, an ultraviolet light sensor, etc. The light emitter is used to emit light. For example, the light emitter may be an infrared light emitter, a monochromatic visible light emitter, a multicolor visible light emitter, a sunlight emitter, a white light emitter, an ultraviolet light emitter, etc.

[0104] The optical device 22 is located on the side of the OLED light-emitting panel 10 away from the color filter layer 20, and the optical device 22 is arranged corresponding to the multiple first light holes 2110. It can be understood that the optical device 22 is arranged on the side of the OLED light-emitting panel 10 away from the color filter layer 20 along the thickness direction of the OLED display screen 100. The present application does not specifically limit the number of the first light holes 2110 corresponding to the optical device 22, and can be specifically designed according to the size of the optical device 22 and the size of the first light holes 2110. Since the optical device 22 is arranged corresponding to the multiple first light holes 2110, the optical device 22 can receive and / or emit light through the corresponding multiple first light holes 2110, so as to facilitate the realization of corresponding functions (for example: ambient light detection, fingerprint recognition, facial recognition, proximity detection, etc.) according to the light received and / or emitted by the optical device 22. Of course, in other embodiments, the optical device 22 can also be set corresponding to one or more second light holes 220. In this case, the optical device 22 can receive and / or emit light through the corresponding multiple first light holes 2110 and the corresponding one or more second light holes 220.

[0105] like Fig.34 As shown, the present application also provides an electronic device 1000. Fig.34 The schematic diagram of the structure of an electronic device 1000 provided in an embodiment of the present application. The electronic device 1000 may be a device with a display function, such as a mobile phone, a tablet, a laptop computer, a watch, etc. The present application embodiment takes a mobile phone as an example, which may be a straight-plate mobile phone, a foldable mobile phone, etc. The electronic device 1000 includes a housing 301 and the above-mentioned OLED display assembly 200.

[0106] Please refer to Fig.34 and Fig.35 , Fig.35 for Fig.34Schematic diagram of the exploded electronic device 1000 shown. The housing 301 may include a middle frame 310 and a back cover 311. The middle frame 310 and the back cover 311 may be integrally formed, or may be connected together in a detachable or non-detachable manner. The middle frame 310 may be approximately a rectangular frame, a square frame, a circular frame, etc. The back cover 311 may be approximately a rectangular cover, a square cover, a circular cover, etc. The material of the middle frame 310 may include one or more of metal, alloy, carbon fiber, plastic, ceramic, glass, etc. The material of the back cover 311 may include one or more of metal, alloy, carbon fiber, plastic, ceramic, glass, etc. The material of the middle frame 310 may be the same as or different from the material of the back cover 311.

[0107] A receiving space 303 is formed between the housing 301 and the OLED display screen 100. Specifically, the OLED display screen 100 is connected to the side of the middle frame 310 away from the rear cover 311, and is arranged opposite to and spaced from the rear cover 311, thereby forming the receiving space 303. At least one optical device 22 is located in the receiving space 303.

[0108] The OLED display assembly 200 and the electronic device 1000 provided in the present application include the OLED display 100 described in any of the above embodiments, so the color filter layer 20 can reduce the external ambient light from entering the OLED display 100 and causing reflection, thereby improving the contrast of the OLED display 100 and improving the use effect of the OLED display 100 under strong light. Compared with the solution using a polarizer, the color filter layer 20 in this solution can have a higher transmittance and be thinner, which is conducive to improving the brightness of the display screen and being suitable for the thin and light design of the OLED display 100. In addition, at least one first light shielding portion 211 of each filter unit 201 has a first light hole 2110, that is, the filter units 201 of the entire color filter layer 20 all have the first light hole 2110, so that the design of the optical device 22 under the screen can be realized, and the reflectivity and light transmittance of the entire screen can be uniform, so that the position of the optical device 22 under the screen can be hidden, so that the optical device 22 under the screen is not easily seen by the user.
