[0108] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0109] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0110] This application provides a display panel. Please refer to Figures 1 and 2. Figure 1 is a top view of the display panel provided in this application, and Figure 2 is a cross-sectional view of the display panel provided in Figure 1 (Figure 2 can be a cross-sectional view of the display panel provided in Figure 1 along line A1-A1). The display area of ​​the display panel 10 includes a light-sensitive display area Q1 and a normal display area Q2 located around the light-sensitive display area Q1. Here, the display panel 10 can be an organic light-emitting diode (OLED) display panel. OLED display panels have many advantages, such as self-illumination, low driving voltage, high luminous efficiency, short response time, high clarity and contrast, wide operating temperature range, and the ability to achieve flexible display and large-area full-color display.

[0111] The display area of ​​the display panel 10 can be an area for displaying images or text. The light-sensing display area Q1 can be a display area corresponding to a light-sensing element. Since the light-sensing element needs to operate based on the collected light, the light-sensing display area Q1 has a certain light transmittance to ensure the normal operation of the light-sensing element. For example, the light-sensing element may include: an ambient light sensor, a fingerprint module, an under-display camera, etc. The light-sensing display area Q1 shown in Figure 1 can correspond to an ambient light sensor. The display area of ​​the display panel 10 may also have multiple light-sensing display areas Q1 to correspond to different light-sensing elements; this embodiment does not limit this. The normal display area Q2 is the display area other than the light-sensing display areas Q1, and this embodiment does not limit the light transmittance of the normal display area Q2.

[0112] The display panel includes: a driving backplane 11, a light-emitting device 12, an encapsulation layer 13, and an auxiliary color resist layer 14.

[0113] There are multiple light-emitting devices 12, all located on the same side of the driving backplate 11. Here, the light-emitting devices 12 are used to emit light beams in a direction away from the driving backplate 11. For example, the multiple light-emitting devices 12 may include various light-emitting devices 12 emitting different colors of light, such as red, green, and blue light-emitting devices. All the multiple light-emitting devices 12 can be electrically connected to the driving backplate 11, and the driving backplate 11 can control the light-emitting state and brightness of each light-emitting device 12.

[0114] The encapsulation layer 13 is located on the side of the plurality of light-emitting devices 12 facing away from the driving backplate 11. Here, the encapsulation layer 13 can cover each light-emitting device 12 located on the driving backplate 11, thereby encapsulating each light-emitting device 12 to prevent water and oxygen in the external environment from corroding the light-emitting devices 12 and avoiding the failure of the light-emitting devices 12. For example, the encapsulation layer 13 may include: a first inorganic encapsulation layer, an organic encapsulation layer and a second inorganic encapsulation layer stacked together.

[0115] The auxiliary color resist layer 14 is located on the side of the encapsulation layer 13 facing away from the driving backplate 11. The orthographic projection of the auxiliary color resist layer 14 on the driving backplate 11 lies between the orthographic projections of two adjacent light-emitting devices 12 on the driving backplate 11. The auxiliary color resist layer 14 includes at least two layers of auxiliary color resist portions 141 stacked together, and each layer of auxiliary color resist portions 141 has a different color. The number of auxiliary color resist portions 141 can vary: the auxiliary color resist layer 14 can include two layers of auxiliary color resist portions 141, or more than two layers of auxiliary color resist portions 141, for example, three layers.

[0116] Here, the auxiliary color resist 141 can be used to transmit one color of light and block other colors of light. By stacking at least two auxiliary color resists 141 of different colors, multiple colors of light emitted by the light-emitting device 12 can be blocked. Therefore, the auxiliary color resist layer 14 can be used to block the light between two adjacent light-emitting devices 12, thereby reducing reflectivity and avoiding crosstalk between two adjacent light-emitting devices 12. That is, the auxiliary color resist layer 14 can replace the black matrix (BM) layer.

[0117] The auxiliary color resist layer 14 is distributed at least within the photosensitive display area Q1, and the auxiliary color resist layer 14 has a light-transmitting hole H that penetrates at least one auxiliary color resist portion 141. Here, the light-transmitting hole H of the auxiliary color resist layer 14 can be in several cases: the light-transmitting hole H can penetrate one auxiliary color resist portion 141, or it can penetrate more than one auxiliary color resist portion 141, for example, the light-transmitting hole H can penetrate two auxiliary color resist portions 141.

[0118] It should be noted that Figure 2 only exemplarily shows two different auxiliary color resist layers 14, but the embodiments of this application are not limited to this. By adjusting the passage of the light-transmitting aperture H, the wavelength range of light that can be transmitted through the photosensitive display area Q1 can be adjusted so that this wavelength range overlaps with the photosensitive wavelength range of the photosensitive element, which is the wavelength range of light that the photosensitive element can collect and sense when it is working. This can improve the matching with the photosensitive element, reduce the transmission of light other than the photosensitive wavelength range of the photosensitive element, and thus improve the effect of the auxiliary color resist layer 14 in reducing reflectivity and preventing crosstalk.

[0119] In addition, in this application, the light-transmitting aperture H can be a through hole. Alternatively, the light-transmitting aperture H can also be a blind hole. By adjusting the depth of the light-transmitting aperture H, the transmittance at the light-transmitting aperture H can be adjusted.

[0120] In summary, this application provides a display panel with an auxiliary color resist layer. This auxiliary color resist layer includes at least two stacked auxiliary color resist portions, each of different colors. Thus, the auxiliary color resist layer can block at least three colors of light. For the portion of the auxiliary color resist layer distributed within the photosensitive display area, by providing a light-transmitting hole penetrating at least one auxiliary color resist portion, it can be ensured that the auxiliary color resist layer allows light of a specific wavelength to pass through. Furthermore, by adjusting the penetration of the light-transmitting hole, this specific wavelength can be controlled, thereby improving the matching between the wavelength of light transmitted to the photosensitive display area and the photosensitive wavelength of the photosensitive element, enabling the photosensitive element to function normally.

[0121] In this application, the arrangement of the light-emitting devices can be varied. One exemplary embodiment is shown in Figure 3, which is a top view of a portion of the structure in another display panel provided in this application (Figure 3 can be a top view of a portion of the structure in the light-sensitive display area Q1). The plurality of light-emitting devices 12 includes: a plurality of first-type light-emitting devices 12a and a plurality of second-type light-emitting devices 12b. Both the first-type light-emitting devices 12a and the second-type light-emitting devices 12b are arranged in multiple columns along the first direction X1 and in multiple rows along the second direction X2. The light-emitting devices 12 in adjacent rows can be staggered, and the light-emitting devices 12 in adjacent columns can also be staggered. For example, the first-type light-emitting device 12a can be a green light-emitting device, and the second-type light-emitting device 12b can include: alternating red light-emitting devices 12b1 and blue light-emitting devices 12b2.

[0122] The auxiliary color resist layer 14 includes a plurality of auxiliary color resist blocks B1 located in the light-sensitive display area Q1. An auxiliary color resist block B1 is distributed in the first direction X1 between two adjacent first-type light-emitting devices 12a in a row of first-type light-emitting devices 12a, and in the second direction X2 between two adjacent second-type light-emitting devices 12b in a column of second-type light-emitting devices 12b.

[0123] At least some of the auxiliary color resist blocks B1 have light-transmitting holes H. In the driving backplate 11, the area corresponding to the auxiliary color resist block B1 has no wiring, or the number of wirings is small. By providing light-transmitting holes H in the auxiliary color resist blocks B1, the location of the wiring can be avoided, thereby preventing the wiring from reducing the light transmittance of the light-sensing display area.

[0124] In addition, the auxiliary color resist layer 14 also includes other parts B2 besides the multiple auxiliary color resist blocks B1. In the driving backplane 11, the other parts B2 may be provided with light-transmitting holes H, or they may not be provided with light-transmitting holes H. This application embodiment does not impose any restrictions on this. When the other parts B2 are not provided with light-transmitting holes H, it can avoid the traces from reflecting ambient light, thereby reducing the reflectivity.

[0125] The following explains the types and transmittance of auxiliary color blocks:

[0126] Please refer to Figure 4, which is a schematic diagram of a partial structure in another display panel provided in an embodiment of this application. The auxiliary color resist layer 14 includes at least two layers of auxiliary color resist parts 141 stacked together. For example, the colors of the auxiliary color resist parts 141 may include red, green, and blue. Then, the auxiliary color resist blocks B1 may include the following four types: the first type of auxiliary color resist block B11 is composed of red auxiliary color resist part 141-R and green auxiliary color resist part 141-G stacked together; the second type of auxiliary color resist block B12 is composed of blue auxiliary color resist part 141-B and red auxiliary color resist part 141-R stacked together; the third type of auxiliary color resist block B13 is composed of blue auxiliary color resist part 141-B and green auxiliary color resist part 141-G stacked together; and the fourth type of auxiliary color resist block B14 is composed of blue auxiliary color resist part 141-B, red auxiliary color resist part 141-R, and green auxiliary color resist part 141-G stacked together. However, this application is not limited to these types. These four types of auxiliary color resist blocks B1 can be applied to the light-sensitive display area and the normal display area.

[0127] It should be noted that the embodiments of this application do not restrict the stacking order of the auxiliary color resist parts 141 in the auxiliary color resist block B1. For example, along the direction away from the drive backplate 11, the colors of at least two auxiliary color resist parts 141 are red and blue in sequence, or the colors of at least two auxiliary color resist parts 141 are blue and green in sequence, or the colors of at least two auxiliary color resist parts 141 are green and red in sequence, or the colors of at least two auxiliary color resist parts 141 are red, blue and green in sequence.

[0128] This application does not limit the type of auxiliary color resist block B1 included in the auxiliary color resist layer 14. The display panel shown in Figure 4, which includes four types of auxiliary color resist blocks B1, is merely illustrative, and this application is not limited thereto. The display panel provided in this application embodiment can select from the four types of auxiliary color resist blocks B11 as needed; that is, the auxiliary color resist layer 14 can include at least one of the above four types of auxiliary color resist blocks B11. For example, the auxiliary color resist blocks B1 in different areas can be the same for ease of manufacturing. Alternatively, the auxiliary color resist blocks B1 in different areas can be different to meet the needs of different areas.

[0129] Furthermore, the thickness of each auxiliary color resist layer 141 can range from 0.5 micrometers to 4 micrometers. Also, the thickness of each auxiliary color resist layer 141 can be the same or different; this embodiment does not impose any limitation on this.

[0130] In this application embodiment, the transmittance of the four types of auxiliary color resist blocks B1 and the black matrix layer BM were tested and compared. Please refer to Figure 5, which is a transmittance spectrum of the four types of auxiliary color resist blocks provided in this application embodiment. The horizontal axis of Figure 5 represents wavelength in nanometers, and the vertical axis represents transmittance. The transmittance curves shown in Figure 5 can reflect the transmittance performance of the four auxiliary color resist layers for light of different wavelengths.

[0131] Among them, the first curve S1 is the transmittance curve of the first type of auxiliary color block B11, the second curve S2 is the transmittance curve of the second type of auxiliary color block B12, the third curve S3 is the transmittance curve of the third type of auxiliary color block B13 superimposed, the fourth curve S4 is the transmittance curve of the fourth type of auxiliary color block B14, and the fifth curve S5 is the transmittance curve of the black matrix layer BM.

[0132] The transmittance curve S5 of the black matrix layer BM exhibits extremely low transmittance for both visible light (380 nm-780 nm) and infrared light (greater than 780 nm), meaning the black matrix layer can block both visible and infrared light. The transmittance curves (S1, S2, S3, S4, and S5) of the four auxiliary color resist blocks B1 all show extremely low transmittance for visible light, thus all four types of auxiliary color resist blocks B1 can block visible light. Furthermore, the transmittance curves of the four types of auxiliary color resist blocks B1 also show high transmittance for infrared light; for example, the transmittance of the four types of auxiliary color resist blocks B1 for light with a wavelength of 940 nm is greater than 60%. On the one hand, since the human eye cannot perceive infrared light, the auxiliary color resist layers can replace the functions of the black matrix layer in reducing reflectivity and preventing crosstalk. On the other hand, current light-sensing elements include infrared sensors with an infrared wavelength. Therefore, the auxiliary color resist block B1 does not need to be provided with a light-passing hole in the light-sensing display area to match the light-sensing wavelength of the infrared sensor, thereby simplifying the manufacturing process of the display panel.

[0133] In this application, the auxiliary color resist block in the photosensitive display area can be provided with a light-transmitting hole to ensure that the photosensitive display area has a certain transmittance to the photosensitive wavelength of the mounted photosensitive element. The following describes the setting of the light-transmitting hole in the auxiliary color resist block using two exemplary embodiments:

[0134] In a first exemplary embodiment, please refer to FIG6, which is a cross-sectional structural schematic diagram of the display panel provided in FIG3 (FIG6 may be a cross-sectional structural schematic diagram of the display panel provided in FIG3 at A2-A2). The at least two auxiliary color resist parts 141 in the auxiliary color resist block B1 include: a first auxiliary color resist part 141a and a second auxiliary color resist part 141b stacked along the direction away from the encapsulation layer 13.

[0135] Wherein, at least a portion of the auxiliary color resist block B1 has a light-transmitting aperture H that satisfies at least one of the following conditions:

[0136] (1) For the first type of light-transmitting hole configuration, please refer to Figure 6. The light-transmitting hole H passes through the second auxiliary color resist part 141b and the first auxiliary color resist part 141a in sequence. That is, there is no auxiliary color resist part blocking the light-transmitting hole H, so both visible light and infrared light can pass through the light-transmitting hole H.

[0137] This application embodiment tested the transmittance of the light-sensitive display area under various light-transmitting hole settings. Please refer to Figure 7, which is a transmittance spectrum of six light-sensitive display areas provided in this application embodiment. The six light-sensitive display areas have the same test conditions: the aperture ratio of the light-sensitive display area is 3.47%, which is the ratio of the total area of ​​all light-transmitting holes to the total area of ​​the light-sensitive display area, and the thickness of each auxiliary color resist layer is 2 micrometers.

[0138] Curve T1 represents the transmittance of the light-sensitive display area shown in Figure 6. As can be seen from curve T1, the light-sensitive display area shown in Figure 6 has high transmittance for both visible and infrared light bands. Therefore, the light-sensitive display area can transmit both visible and infrared light. Thus, the light-sensitive element configured in the light-sensitive display area may include at least one of a visible light sensor and an infrared sensor.

[0139] Furthermore, in the first configuration of the light-transmitting hole, the light-transmitting hole H is composed of the second through hole of the second auxiliary color resist part 141b and the first through hole of the first auxiliary color resist part 141a. However, the embodiments of this application do not limit the relative size of these two through holes, and specifically include the following three cases:

[0140] The second through hole can be larger than the first through hole, and the orthographic projection of the first through hole on the drive back plate 11 is located within the orthographic projection of the second through hole on the drive back plate 11, so as to ensure the transmittance of the light-transmitting hole H.

[0141] Alternatively, the second through hole can be smaller than the first through hole, and the orthographic projection of the second through hole on the drive back plate 11 is located within the orthographic projection of the first through hole on the drive back plate 11, so as to ensure the transmittance of the light-transmitting hole H. The edge of the second auxiliary color resist 141b facing the light-transmitting hole H covers the edge of the first auxiliary color resist 141a facing the light-transmitting hole H, so as to prevent the second auxiliary color resist 141b from peeling off.

[0142] Alternatively, the second through-hole can be equal to the first through-hole, that is, the edge of the second auxiliary color resist portion 141b facing the light-transmitting hole H is flush with the edge of the first auxiliary color resist portion 141a facing the light-transmitting hole H. This avoids areas where only a single layer of auxiliary color resist exists, thus improving the effect of reducing reflectivity and preventing crosstalk. It should be noted that the display panel shown in FIG6 includes all three situations for illustration only, but this application is not limited thereto. The display panel provided in the embodiments of this application may include at least one of the three situations. For example, the arrangement in different areas can be the same to facilitate manufacturing. The arrangement in different areas can also be different to adapt to the needs of different areas.

[0143] Please refer to FIG8 for an exemplary embodiment. FIG8 is a schematic diagram of another display panel structure provided in this application embodiment. The auxiliary color resist layer 14 includes a first auxiliary color resist portion 141a and a second auxiliary color resist portion 141b stacked along the direction away from the encapsulation layer 13. The color of the first auxiliary color resist portion 141a is red, and the color of the second auxiliary color resist portion 141b is blue.

[0144] The light-transmitting aperture H includes a first through-hole H1 and a second through-hole H2, wherein the first through-hole H1 penetrates the first auxiliary color resist section 141a, and the second through-hole H2 penetrates the second auxiliary color resist section 141b. In the direction parallel to the drive backplate 11, the size of the first through-hole H1 is smaller than the size of the second through-hole H2. Therefore, the relative sizes of the first through-hole H1 and the second through-hole H2 are the same for all light-transmitting apertures H, which reduces manufacturing difficulty.

[0145] For example, in the direction parallel to the drive backplate 11, the distance between the edge of the first auxiliary color resist 141a facing the light-transmitting hole H and the edge of the second auxiliary color resist 141b facing the light-transmitting hole H can be 1.5 micrometers. This can ensure that the two holes are aligned, thereby improving the transmittance at the light-transmitting hole H.

[0146] (2) For the second type of light-transmitting hole configuration, please refer to Figure 9. Figure 9 is a schematic diagram of another cross-sectional structure of the display panel provided in Figure 3 (Figure 9 can be a schematic diagram of the cross-sectional structure of the display panel provided in Figure 3 at A2-A2). The light-transmitting hole H only penetrates the second auxiliary color resist part 141b. That is, only the first auxiliary color resist part 141a blocks the light-transmitting hole H. Therefore, only light within the wavelength band corresponding to the first auxiliary color resist part 141a and infrared light can pass through the light-transmitting hole H. For example, the color of the first auxiliary color resist part 141a is any one of red, green or blue.

[0147] When the color of the first auxiliary color resist 141a is red, please refer to curve T2 in Figure 7 for the transmittance of the light-sensitive display area. As can be seen from curve T2, the light-sensitive display area has high transmittance for both the red light band and the infrared band, so the light-sensitive display area can transmit red light and infrared light.

[0148] For example, the light-sensing element includes a distance sensor. Light within the photosensitive wavelength range is reflected after being incident on an object. The distance sensor receives the reflected light, and the received light signal is processed to obtain a light intensity value, which reflects the distance between the object and the distance sensor. Since the photosensitive wavelength range of the distance sensor can be 680 nm to 1000 nm, the light-sensing element configured in this light-sensing display area can include at least one of a distance sensor and an infrared sensor.

[0149] When the color of the first auxiliary color resist 141a is green, please refer to curve T3 in Figure 7 for the transmittance of the light-sensitive display area. As can be seen from curve T3, the light-sensitive display area has high transmittance for both the green light band and the infrared band, so the light-sensitive display area can transmit green light and infrared light.

[0150] For example, the optical sensing element includes a fingerprint module. When a finger presses the screen, light within the photosensitive wavelength range shines on the finger and is reflected. The fingerprint module can receive the reflected light and form an image of a fingerprint. This image information is converted into a digital signal, which is then compared by a processor to confirm identity. Since the photosensitive wavelength range of the fingerprint module can be 550 nanometers, the optical sensing element configured in this optical display area can include at least one of a fingerprint module and an infrared sensor.

[0151] When the color of the first auxiliary color resist 141a is blue, please refer to curve T4 in Figure 7 for the transmittance of the light-sensitive display area. As can be seen from curve T4, the light-sensitive display area has high transmittance for both the blue light band and the infrared band, so the light-sensitive display area can transmit both blue light and infrared light.

[0152] For example, the photosensitive element includes a blood oxygen detector, which emits a light beam within a photosensitive wavelength range. When the light beam passes through the skin, it is received by the blood oxygen detector and converted into an electrical signal. Oxyhemoglobin and deoxyhemoglobin have different absorption rates for different wavelengths of light. By analyzing the absorption of light at different wavelengths, the blood oxygen detector can calculate the ratio of oxyhemoglobin to deoxyhemoglobin, thereby obtaining the blood oxygen saturation. Since the photosensitive wavelength range of the blood oxygen detector can be 400 nm to 460 nm, the photosensitive element configured in this photosensitive display area can include at least one of a blood oxygen detector and an infrared sensor.

[0153] (3) For the third type of light-transmitting hole configuration, please refer to Figure 10. Figure 10 is a schematic diagram of another cross-sectional structure of the display panel provided in Figure 3 (Figure 10 can be a schematic diagram of the cross-sectional structure of the display panel provided in Figure 3 at A2-A2). The light-transmitting hole H only penetrates the first auxiliary color resist part 141a. That is, only the second auxiliary color resist part 141b blocks the light-transmitting hole H. Therefore, only light within the wavelength band corresponding to the second auxiliary color resist part 141b and infrared light can pass through the light-transmitting hole H. For example, the color of the second auxiliary color resist part 141b is any one of red, green or blue. Except for infrared light, the corresponding light-transmitting hole H can allow red light, green light or blue light to pass through.

[0154] For the transmittance of the light-sensing display area under these three conditions, please refer to the embodiment corresponding to the second type of light-passing hole setting. The embodiments of this application will not be described in detail here. Since the light-passing hole H penetrates the first auxiliary color resist 141a located on the side near the drive back plate 11, at least a portion of the second auxiliary color resist 141b is located inside the light-passing hole H.

[0155] Additionally, please refer to Figure 7. The light-sensitive display area corresponding to curve T5 does not have a light-sensitive hole. As can be seen from curve T5, the light-sensitive display area still has high transmittance to the infrared band when no light-sensitive hole is provided in the auxiliary color resist layer. Therefore, the light-sensitive element configured in this light-sensitive display area may include an infrared sensor.

[0156] The colors of the first and second auxiliary color resist portions in the auxiliary color resist block in the first exemplary embodiment will be described below:

[0157] Optionally, referring to Figure 6, the colors of the first auxiliary color resist portion 141a in each auxiliary color resist block B1 are all the same, and the colors of the second auxiliary color resist portion 141b in each auxiliary color resist block B1 are all the same, which facilitates the manufacturing of the auxiliary color resist layer 14.

[0158] The colors of the first auxiliary color resist 141a and the second auxiliary color resist 141b are any two of red, green and blue, respectively. For example, referring to Figures 4 and 6, each auxiliary color resist block B1 can be a first type of auxiliary color resist block B11, or a second type of auxiliary color resist block B12, or a third type of auxiliary color resist block B13.

[0159] Optionally, referring to Figure 6, the plurality of auxiliary color resist blocks B1 include: at least two types of auxiliary color resist blocks B1, wherein the colors of the first auxiliary color resist portion 141a in the different types of auxiliary color resist blocks B1 are different, and / or, the colors of the second auxiliary color resist portion 141b in the different types of auxiliary color resist blocks B1 are different. The following description uses two embodiments:

[0160] In the first embodiment, the plurality of auxiliary color resist blocks B1 include two types of auxiliary color resist blocks B1, and the colors of the first auxiliary color resist portion 141a and the second auxiliary color resist portion 141b include the following three cases:

[0161] (1) In different types of auxiliary color resist blocks B1, only the color of the first auxiliary color resist part 141a is different.

[0162] For example, referring to Figures 4 and 6, the multiple auxiliary color blocks B1 may include: multiple second-type auxiliary color blocks B12 and multiple third-type auxiliary color blocks B13.

[0163] (2) In different types of auxiliary color resist blocks B1, only the color of the second auxiliary color resist part 141b is different.

[0164] For example, referring to Figures 4 and 6, the multiple auxiliary color blocks B1 may include: multiple first-type auxiliary color blocks B11 and multiple third-type auxiliary color blocks B13.

[0165] (3) The colors of the first auxiliary color resist part 141a in different types of auxiliary color resist blocks B1 are different, and the colors of the second auxiliary color resist part 141b in different types of auxiliary color resist blocks B1 are different.

[0166] For example, referring to Figures 4 and 6, the multiple auxiliary color blocks B1 may include: multiple first-type auxiliary color blocks B11 and multiple second-type auxiliary color blocks B12.

[0167] In the second embodiment, the plurality of auxiliary color blocks B1 include: a plurality of first-type auxiliary color blocks B11, a plurality of second-type auxiliary color blocks B12, and a plurality of third-type auxiliary color blocks B13.

[0168] In the first type of auxiliary color resist block B1, the two auxiliary color resist sections 141 are red and green, respectively. In the second type of auxiliary color resist block B1, the two auxiliary color resist sections 141 are blue and red, respectively. In the third type of auxiliary color resist block B1, the two auxiliary color resist sections 141 are blue and green, respectively.

[0169] It should be noted that the display panels shown in Figures 6, 9, and 10 each include only one type of light-transmitting hole H, but this application is not limited to this. Embodiments of this application may also combine any two of the above three types of light-transmitting holes, or include all three types of light-transmitting holes simultaneously.

[0170] Optionally, please refer to Figures 11 and 12. Figure 11 is a top view of a portion of the structure in another display panel provided in an embodiment of this application (Figure 11 may be a top view of a portion of the structure in the light-sensitive display area Q1). Figure 12 is a cross-sectional view of the display panel provided in Figure 11 (Figure 12 may be a cross-sectional view of the display panel provided in Figure 11 at A3-A3). Figure 11 uses the process sequence of the red auxiliary color resist 141-R, the blue auxiliary color resist 141-B, and the green auxiliary color resist 141-G as an example. Multiple auxiliary color resist blocks B1 satisfy the following conditions:

[0171] (1) Please refer to area C1 in Figure 11. At least one first-class auxiliary color resist block B11, and / or at least one second-class auxiliary color resist block B12, and / or at least one third-class auxiliary color resist block B13 are not provided with light-transmitting holes H.

[0172] That is, among the multiple auxiliary color resist blocks B1, there is an auxiliary color resist block B1 without a light-transmitting hole H. This auxiliary color resist block B1 without a light-transmitting hole H can be any one of the following types: first type auxiliary color resist block B11, second type auxiliary color resist block B12, and third type auxiliary color resist block B13, or any two or three types. For example, region C1 uses the second type auxiliary color resist block B12. The transmittance characteristics of the auxiliary color resist block B1 that meets this condition can be referred to curve T5 in Figure 7, which will not be elaborated further in this embodiment.

[0173] (2) Referring to region C2 in Figure 11, the light-transmitting hole H in at least one first-class auxiliary color resist block B11 and / or at least one second-class auxiliary color resist block B12 penetrates through a layer of auxiliary color resist 141, but does not penetrate the auxiliary color resist 141 with red color.

[0174] That is, among the multiple auxiliary color resist blocks B1, there is an auxiliary color resist block B1 whose light-transmitting hole H does not penetrate the red auxiliary color resist portion 141-R, and this auxiliary color resist block B1 can be either the first type of auxiliary color resist block B1 or the second type of auxiliary color resist block B1, or both types. For example, region C2 takes the second type of auxiliary color resist block B12 as an example. The transmittance characteristics of the auxiliary color resist block B1 that meets this condition can be referred to curve T2 in Figure 7, which will not be elaborated further in this embodiment.

[0175] (3) Referring to region C3 in Figure 11, the light-transmitting hole H in at least one first-class auxiliary color resist block B11 and / or at least one third-class auxiliary color resist block B13 penetrates through a layer of auxiliary color resist 141, but does not penetrate the green auxiliary color resist 141.

[0176] That is, among the multiple auxiliary color resist blocks B1, there is an auxiliary color resist block B1 whose light-transmitting hole H does not penetrate the green auxiliary color resist portion 141-G, and this auxiliary color resist block B1 can be any one of the first type of auxiliary color resist block B11 and the third type of auxiliary color resist block B13, or both. For example, region C3 takes the third type of auxiliary color resist block B13 as an example. The transmittance characteristics of the auxiliary color resist block B1 that meets this condition can be referred to curve T3 in Figure 7, which will not be elaborated on in this embodiment. Here, the light-transmitting hole H does not penetrate the green auxiliary color resist portion 141-G, a part of the green auxiliary color resist portion 141-G is filled in the light-transmitting hole H, and the upper surface of the green auxiliary color resist portion 141-G facing away from the driving back plate 11 is flat, which can increase the flatness of the auxiliary color resist layer 14 and reduce the risk of color separation.

[0177] (4) Referring to region C4 in Figure 11, the light-transmitting hole H in at least one second-class auxiliary color resist block B12 and / or at least one third-class auxiliary color resist block B13 penetrates through a layer of auxiliary color resist 141, but does not penetrate the blue-colored auxiliary color resist 141.

[0178] That is, among the multiple auxiliary color resist blocks B1, there is an auxiliary color resist block B1 whose light-transmitting hole H does not penetrate the blue auxiliary color resist portion 141-B, and this auxiliary color resist block B1 can be any one of the second type of auxiliary color resist block B12 and the third type of auxiliary color resist block B13, or both. For example, region C4 takes the second type of auxiliary color resist block B12 as an example. The transmittance characteristics of the auxiliary color resist block B1 that meets this condition can be referred to curve T4 in Figure 7, which will not be elaborated further in this embodiment.

[0179] (5) Referring to region C5 in Figure 11, at least one first-class auxiliary color resist block B11, and / or at least one second-class auxiliary color resist block B12, and / or at least one third-class auxiliary color resist block B13 have light-transmitting holes H that simultaneously penetrate the two auxiliary color resist parts 141.

[0180] That is, among the multiple auxiliary color resist blocks B1, there is an auxiliary color resist block B1 with a light-transmitting hole H that simultaneously penetrates two layers of auxiliary color resist portion 141. The auxiliary color resist block B1 can be any one of the following: a first type of auxiliary color resist block B11, multiple second type of auxiliary color resist blocks B12, and multiple third type of auxiliary color resist blocks B13, or any two or three types. For example, region C5 uses a second type of auxiliary color resist block B12. The transmittance characteristics of the auxiliary color resist block B1 that meets this condition can be referred to curve T1 in Figure 7, which will not be elaborated further in this embodiment.

[0181] Furthermore, in the light-sensitive display area, the proportion of auxiliary color resist blocks B1 that satisfy the above five conditions can range from 0 to 1, meaning that the auxiliary color resist layer 14 can include at least one of the auxiliary color resist blocks B1 that satisfy the above five conditions. For an exemplary embodiment, please refer to Figure 11. Curve T6 in Figure 7 represents the transmittance in the light-sensitive display area shown in Figure 11. For the display panel shown in Figure 11, the proportion of auxiliary color resist blocks B1 that satisfy the above five conditions in the light-sensitive display area is 1 / 5. As can be seen from curve T6, the light-sensitive display area shown in Figure 11 exhibits a certain transmittance for red, blue, green, and infrared light. This demonstrates that when auxiliary color resist blocks B1 satisfying the above five conditions are simultaneously provided in the light-sensitive display area, their transmittance characteristics can be combined to achieve a controllable transmittance spectrum for the light-sensitive display area. Furthermore, by adjusting the proportion of auxiliary color resist blocks B1 that satisfy the above five conditions, the transmittance of the light-sensitive display area for a certain wavelength of light can be adjusted.

[0182] Therefore, in the first exemplary instance, this application can adjust the transmittance spectrum of the photosensitive display area according to the photosensitive band of the photosensitive element corresponding to the photosensitive display area, so that the band with higher transmittance in the transmittance spectrum matches the photosensitive band of the photosensitive element. For example, when the photosensitive band of the photosensitive element is the blue light band and the green light band, the proportion of auxiliary color resist blocks B1 in the photosensitive display area that satisfy the third and fourth conditions above can be larger.

[0183] In the embodiments of this application, there are multiple ways in which the auxiliary color resist blocks B1 that satisfy the above five conditions can be arranged. For example, the five auxiliary color resist blocks B1 are arranged sequentially at intervals along the first direction X1, and in the second direction X2, the auxiliary color resist blocks B1 in adjacent rows are arranged alternately. However, this application is not limited to this.

[0184] In a second exemplary embodiment, please refer to FIG13, which is another cross-sectional structural schematic diagram of the display panel provided in FIG3 (FIG13 may be a cross-sectional structural schematic diagram of the display panel provided in FIG3 at A2-A2). The at least two auxiliary color resist parts 141 in the auxiliary color resist block B1 include: a first auxiliary color resist part 141a, a second auxiliary color resist part 141b and a third auxiliary color resist part 141c stacked in a direction away from the encapsulation layer 13.

[0185] Wherein, at least a portion of the auxiliary color resist block B1 has a light-transmitting aperture H that satisfies at least one of the following conditions:

[0186] (1) For the first type of light-transmitting hole configuration, please refer to Figure 13. The light-transmitting hole H passes through the third auxiliary color resist part 141c, the second auxiliary color resist part 141b, and the first auxiliary color resist part 141a in sequence. That is, since there is no auxiliary color resist part blocking the light-transmitting hole H, both visible light and infrared light can pass through the light-transmitting hole H. Therefore, the light-sensing element configured in this light-sensing display area may include at least one of a visible light sensor and an infrared sensor.

[0187] Furthermore, in the first configuration of the light-transmitting hole, the light-transmitting hole H is composed of the third through-hole of the third auxiliary color resist 141c, the second through-hole of the second auxiliary color resist 141b, and the first through-hole of the first auxiliary color resist 141a. However, the embodiments of this application do not limit the relative sizes of these three types of through-holes. Figure 13 shows three cases: for example, the sizes of the first through-hole, the second through-hole, and the third through-hole increase sequentially; or, the sizes of the first through-hole, the second through-hole, and the third through-hole decrease sequentially; or, the sizes of the first through-hole, the second through-hole, and the third through-hole are the same.

[0188] It should be noted that the display panel shown in Figure 13, which includes all three scenarios, is for illustrative purposes only, and this application is not limited thereto. The display panel provided in the embodiments of this application may include at least one of the three scenarios. For example, the settings in different areas may be the same to facilitate manufacturing. The settings in different areas may also be different to adapt to the needs of different areas.

[0189] Please refer to FIG14 for an exemplary embodiment. FIG14 is a schematic diagram of another display panel structure provided in this application embodiment. The auxiliary color resist layer 14 includes a first auxiliary color resist portion 141a, a second auxiliary color resist portion 141b, and a third auxiliary color resist portion 141c stacked along the direction away from the encapsulation layer 13. The color of the first auxiliary color resist portion 141a is blue, the color of the second auxiliary color resist portion 141b is red, and the color of the third auxiliary color resist portion 141c is green.

[0190] The light-transmitting aperture H includes a first through-hole H1, a second through-hole H2, and a third through-hole H3. The first through-hole H1 penetrates the first auxiliary color resist section 141a, the second through-hole H2 penetrates the second auxiliary color resist section 141b, and the third through-hole H3 penetrates the third auxiliary color resist section 141c. In the direction parallel to the drive backplate 22, the size of the first through-hole H1 is smaller than the size of the second through-hole H2, and the size of the second through-hole H2 is smaller than the size of the third through-hole H3. Therefore, the relative sizes of the first through-hole H1, the second through-hole H2, and the third through-hole H3 are set identically for each light-transmitting aperture H. This reduces manufacturing difficulty and ensures the transmittance of the light-transmitting aperture H.

[0191] For example, in the direction parallel to the drive backplate 11, the distance between the edge of the first auxiliary color resist 141a facing the light-transmitting hole H and the edge of the second auxiliary color resist 141b facing the light-transmitting hole H can be 1.5 micrometers. This can ensure that the two holes are aligned, thereby improving the transmittance at the light-transmitting hole H.

[0192] (2) For the second type of light-transmitting hole configuration, please refer to Figure 15. Figure 15 is a schematic diagram of another cross-sectional structure of the display panel provided in Figure 3 (Figure 15 can be a schematic diagram of the cross-sectional structure of the display panel provided in Figure 3 at A2-A2). The light-transmitting hole H only penetrates the third auxiliary color resist part 141c and the second auxiliary color resist part 141b. That is, only the first auxiliary color resist part 141a blocks the light-transmitting hole H, so only the light in the wavelength band corresponding to the first auxiliary color resist part 141a and infrared light can pass through the light-transmitting hole H.

[0193] For example, when the color of the first auxiliary color resist 141a is red, the light-sensitive display area can transmit red light and infrared light. Therefore, the light-sensitive element configured in the light-sensitive display area may include at least one of a distance sensor and an infrared sensor.

[0194] When the color of the first auxiliary color resist portion 141a is green, the photosensitive display area can transmit both green light and infrared light. Therefore, the photosensitive element configured in the photosensitive display area may include at least one of a fingerprint module and an infrared sensor.

[0195] When the color of the first auxiliary color resist 141a is blue, the light-sensitive display area can transmit both blue light and infrared light. Therefore, the light-sensitive element configured in the light-sensitive display area may include at least one of a blood oxygen detector and an infrared sensor.

[0196] Furthermore, in the second type of light-transmitting hole configuration, the light-transmitting hole H is composed of the third through-hole of the third auxiliary color resist 141c and the second through-hole of the second auxiliary color resist 141b. However, the embodiments of this application do not limit the relative sizes of these two through-holes. Figure 15 shows three cases: for example, the size of the second through-hole is smaller than the size of the third through-hole, or the size of the second through-hole is larger than the size of the third through-hole, or the size of the second through-hole is equal to the size of the third through-hole.

[0197] It should be noted that the display panel shown in Figure 15, which includes all three scenarios, is for illustrative purposes only, and this application is not limited thereto. The display panel provided in the embodiments of this application may include at least one of the three scenarios. For example, the settings in different areas may be the same to facilitate manufacturing. The settings in different areas may also be different to adapt to the needs of different areas.

[0198] (3) For the third type of light-transmitting hole configuration, please refer to Figure 16. Figure 16 is a schematic diagram of another cross-sectional structure of the display panel provided in Figure 3 (Figure 16 can be a schematic diagram of the cross-sectional structure of the display panel provided in Figure 3 at A2-A2). The light-transmitting hole H only penetrates the second auxiliary color resist part 141b and the first auxiliary color resist part 141a. That is, only the third auxiliary color resist part 141c blocks the light-transmitting hole H, so only light within the wavelength band corresponding to the third auxiliary color resist part 141c and infrared light can pass through the light-transmitting hole H. The light-sensing element configured in this case can refer to the second type of light-transmitting hole configuration, which will not be elaborated further in this embodiment.

[0199] Furthermore, in the third configuration of the light-transmitting hole, the light-transmitting hole H is composed of a second through-hole in the second auxiliary color resist part 141b and a first through-hole in the first auxiliary color resist part 141a. However, the embodiments of this application do not limit the relative sizes of these two through-holes. Figure 16 illustrates three cases, for example, the size of the second through-hole is smaller than the size of the first through-hole, or the size of the second through-hole is larger than the size of the first through-hole, or the size of the second through-hole is equal to the size of the first through-hole.

[0200] It should be noted that the display panel shown in Figure 16 includes all three situations mentioned above only for illustration purposes, but this application is not limited to this. The display panel provided in the embodiments of this application may include at least one of the three situations. For example, the setting situation in different areas may be the same to facilitate manufacturing. The setting situation in different areas may also be different to adapt to the needs of different areas. (4) For the fourth setting situation of the light-transmitting hole, please refer to Figure 17. Figure 17 is another cross-sectional structural schematic diagram of the display panel provided in Figure 3 (Figure 17 may be a cross-sectional structural schematic diagram of the display panel provided in Figure 3 at A2-A2). The light-transmitting hole H only penetrates the third auxiliary color resist part 141c and the first auxiliary color resist part 141a. That is, only the second auxiliary color resist part 141b blocks the light-transmitting hole H, so only the light in the band corresponding to the second auxiliary color resist part 141b and infrared light can pass through the light-transmitting hole H. The light-sensing element configured in this case can refer to the second setting situation of the light-transmitting hole, which will not be elaborated on in the embodiments of this application.

[0201] Furthermore, in the fourth configuration of the light-transmitting hole, the light-transmitting hole H is composed of the third through-hole of the third auxiliary color resist 141c and the first through-hole of the first auxiliary color resist 141a. However, the embodiments of this application do not limit the relative sizes of these two through-holes. Figure 17 shows three cases, for example, the size of the third through-hole is smaller than the size of the first through-hole, or the size of the third through-hole is larger than the size of the first through-hole, or the size of the third through-hole is equal to the size of the first through-hole.

[0202] It should be noted that the display panel shown in Figure 17, which includes all three scenarios, is for illustrative purposes only, and this application is not limited thereto. The display panel provided in the embodiments of this application may include at least one of the three scenarios. For example, the settings in different areas may be the same to facilitate manufacturing. The settings in different areas may also be different to adapt to the needs of different areas.

[0203] (5) For the fifth type of light-transmitting hole configuration, please refer to Figure 18. Figure 18 is a schematic diagram of another cross-sectional structure of the display panel provided in Figure 3 (Figure 18 can be a schematic diagram of the cross-sectional structure of the display panel provided in Figure 3 at A2-A2). The light-transmitting hole H only penetrates the third auxiliary color resist part 141c. That is, at the light-transmitting hole H, the first auxiliary color resist part 141a and the second auxiliary color resist part 141b overlap and block visible light, so only infrared light can pass through the light-transmitting hole H. Therefore, the light-sensing element configured in this light-sensing display area may include: an infrared sensor.

[0204] (6) For the sixth type of light-transmitting hole configuration, please refer to Figure 19. Figure 19 is a schematic diagram of another cross-sectional structure of the display panel provided in Figure 3 (Figure 19 can be a schematic diagram of the cross-sectional structure of the display panel provided in Figure 3 at A2-A2). The light-transmitting hole H only penetrates the second auxiliary color resist part 141b. That is, at the light-transmitting hole H, the first auxiliary color resist part 141a and the third auxiliary color resist part 141c overlap and block visible light, so only infrared light can pass through the light-transmitting hole H. Therefore, the light-sensing element configured in this light-sensing display area may include: an infrared sensor.

[0205] (7) For the seventh type of light-transmitting hole configuration, please refer to Figure 20. Figure 20 is a schematic diagram of another cross-sectional structure of the display panel provided in Figure 3 (Figure 20 can be a schematic diagram of the cross-sectional structure of the display panel provided in Figure 3 at A2-A2). The light-transmitting hole H only penetrates the first auxiliary color resist part 141a. That is, at the light-transmitting hole H, the third auxiliary color resist part 141c and the second auxiliary color resist part 141b overlap and block visible light, so only infrared light can pass through the light-transmitting hole H. Therefore, the light-sensing element configured in this light-sensing display area may include: an infrared sensor.

[0206] The colors of the first and second auxiliary color resist portions in the auxiliary color resist block in the second exemplary embodiment will be described below:

[0207] Please refer to Figure 12. The first auxiliary color resist portion 141a in each auxiliary color resist block B1 has the same color, the second auxiliary color resist portion 141b in each auxiliary color resist block B1 has the same color, and the third auxiliary color resist portion 141c in each auxiliary color resist block B1 has the same color. This facilitates the manufacturing of the auxiliary color resist layer 14.

[0208] The first auxiliary color resist 141a is colored one of red, green, and blue; the second auxiliary color resist 141b is colored another of red, green, and blue; and the third auxiliary color resist 141c is colored yet another of red, green, and blue. For example, the first auxiliary color resist 141a is green, the second auxiliary color resist 141b is red, and the third auxiliary color resist 141c is blue.

[0209] It should be noted that Figures 13 to 20 each only show one type of light-transmitting aperture H, but this application is not limited to this. Embodiments of this application can also include any combination of the above seven types of light-transmitting apertures.

[0210] Optionally, please refer to Figures 21 and 22. Figure 21 is a top view of a portion of the structure in another display panel provided in this embodiment (Figure 21 may be a top view of a portion of the structure in the light-sensitive display area Q1). Figure 22 is a cross-sectional view of the display panel provided in Figure 21 (Figure 22 may be a cross-sectional view of the display panel provided in Figure 21 at A4-A4). Figure 20 uses the process sequence of the red auxiliary color resist 141-R, the blue auxiliary color resist 141-B, and the green auxiliary color resist 141-G as an example. Multiple auxiliary color resist blocks B1 satisfy the following conditions:

[0211] (1) Referring to area D1 in Figure 21, at least one auxiliary color resist block B1 does not have a light-transmitting hole H. That is, the at least one auxiliary color resist block B1 can allow infrared light to pass through.

[0212] (2) Referring to region D2 in Figure 21, at least one light-transmitting hole H in an auxiliary color resist block B1 penetrates an auxiliary color resist section 141. That is, the at least one auxiliary color resist block B1 allows infrared light to pass through.

[0213] (3) Referring to region D3 in Figure 21, at least one light-transmitting hole H in the auxiliary color resist block B1 penetrates both layers of auxiliary color resist 141, but does not penetrate the red auxiliary color resist 141. That is, the at least one auxiliary color resist block B1 allows red light and infrared light to pass through.

[0214] (4) Referring to region D4 in Figure 21, at least one light-transmitting hole H in the auxiliary color resist block B1 penetrates both layers of auxiliary color resist 141, but does not penetrate the green auxiliary color resist 141. That is, the at least one auxiliary color resist block B1 allows green light and infrared light to pass through.

[0215] (5) Referring to area D5 in Figure 21, at least one light-transmitting hole H in the auxiliary color resist block B1 penetrates both layers of auxiliary color resist 141, but does not penetrate the blue auxiliary color resist 141. That is, the at least one auxiliary color resist block B1 allows blue light and infrared light to pass through.

[0216] (6) Referring to region D6 in Figure 21, at least one light-transmitting hole H in the auxiliary color resist block B1 simultaneously penetrates the three layers of auxiliary color resist 141. That is, the at least one auxiliary color resist block B1 allows visible light and infrared light to pass through.

[0217] Furthermore, in the photosensitive display area, the proportion of auxiliary color resist blocks B1 that satisfy the above six conditions can range from 0 to 1, meaning that the auxiliary color resist layer 14 can include at least one of the auxiliary color resist blocks B1 that meet the above six conditions. Therefore, in the second exemplary embodiment, by adjusting the proportion of auxiliary color resist blocks B1 that satisfy the above six conditions, the photosensitive display area can be adjusted to have a higher transmittance for a certain wavelength of light. Thus, this application can also adjust the transmittance spectrum of the photosensitive display area according to the photosensitive wavelength of the photosensitive element corresponding to the photosensitive display area, so that the wavelength with higher transmittance in the transmittance spectrum matches the photosensitive wavelength of the photosensitive element.

[0218] The shape, size, and setup cycle of the light-transmitting aperture are explained below:

[0219] Please refer to Figure 23, which is a top view of a portion of the structure in another display panel provided in this application embodiment (Figure 23 may be a top view of a portion of the structure in the light-sensing display area Q1). The shape of the light-transmitting hole H may include at least one of the following: triangle, rectangle, circle, ellipse, rhombus, pentagon, hexagon, heptagon, octagon, trapezoid, or other irregular shapes. That is, the shapes of the multiple light-transmitting holes H in the light-sensing display area Q1 may be the same, or may include several of these shapes simultaneously.

[0220] The arrangement period of the light-transmitting holes H can include at least one of the following: 1 / 2 period, single period, 2 periods, 3 periods, and 4 periods. Among them, 1 / 2 period means that each auxiliary color resist block B1 has 2 light-transmitting holes H, single period means that each auxiliary color resist block B1 has 1 light-transmitting hole H, and 4 periods means that every 4 auxiliary color resist blocks B1 have 1 light-transmitting hole H.

[0221] In the direction parallel to the drive backplate 11, the size of the multiple light-transmitting holes H can be the same or different. This application embodiment does not limit this.

[0222] The aperture ratio of the light-sensing display area can be adjusted by setting and adjusting the arrangement period or the size of a single light-transmitting hole. For example, please refer to Table 1, which shows the aperture ratio and transmittance in the case of two-layer perforation provided in the embodiments of this application (the structure of the display panel corresponding to Table 1 can be seen in Figure 6). The transmittance is the transmittance for light with a wavelength of 550 nanometers. As shown in Table 1, the aperture ratio of the light-sensing display area is positively correlated with its transmittance; that is, the larger the aperture ratio, the greater the transmittance.

[0223] Since the light transmittance of the light-sensing display area is greater than the light transmittance threshold of the light-sensing element, the light-sensing element can identify ambient light and operate normally. Therefore, this application can determine the ideal transmittance required for the light-sensing display area based on the transmittance threshold of the light-sensing element, and then adjust the aperture ratio of the light-sensing display area by adjusting the arrangement period or the size of a single light-transmitting hole, so that the actual transmittance of the light-sensing display area is greater than or equal to the ideal transmittance, thereby enabling the light-sensing display area to meet the light transmission requirements of the light-sensing element.

[0224] Table 1

[0225] In this application, the display panel can employ color filter on encapsulation (COE) technology. COE technology replaces the polarizer by manufacturing a color filter (CF) on the encapsulation layer, which can reduce reflectivity and increase brightness. The color filter has selective light transmittance, meaning that only light of specific wavelengths can pass through the color filter.

[0226] In a first exemplary embodiment, a plurality of primary color blocks may be provided in the display panel, and the primary color blocks have selective transmittance for a certain color of light.

[0227] Please refer to Figure 24, which is a schematic diagram of another display panel structure provided in an embodiment of this application. The display panel further includes: multiple main color blocks 15, which are located on the side of the encapsulation layer 13 away from the light-emitting device 12. Each main color block 15 corresponds to one of the multiple light-emitting devices 12, and the orthographic projection of the main color block 15 on the driving back plate 11 overlaps with the orthographic projection of the corresponding light-emitting device 12 on the driving back plate 11. In this way, the light emitted by each light-emitting device 12 can pass through the corresponding main color block 15 before being emitted. The main color block 15 can transmit specific colors of light emitted by the light-emitting device 12 while filtering out other colors, thereby ensuring good color purity of the display panel during the display process. Color purity refers to the purity of the colors displayed by the display panel.

[0228] Among them, the multiple main color blocks 15 include: at least two types of main color blocks 15 with different colors, the at least two types of main color blocks 15 correspond to at least two layers of auxiliary color resists 141, and the color of one type of main color block 15 is the same as the color of the corresponding auxiliary color resist 141.

[0229] For example, the plurality of light-emitting devices 12 may include: a green light-emitting device 12a, a red light-emitting device 12b1, and a blue light-emitting device 12b2. Correspondingly, the plurality of main color resist blocks 15 may include: a green main color resist block 15a, a red main color resist block 15b, and a blue main color resist block 15c. The green main color resist block 15a can be manufactured in the same layer and with the same material as the green auxiliary color resist portion 141-G, the red main color resist block 15b can be manufactured in the same layer and with the same material as the red auxiliary color resist portion 141-R, and the blue main color resist block 15c can be manufactured in the same layer and with the same material as the blue auxiliary color resist portion 141-B, thereby simplifying the manufacturing process.

[0230] It should be noted that Figure 24 shows various types of auxiliary color resist blocks, but the embodiments of this application do not limit the display panel to include all of these types of auxiliary color resist blocks simultaneously. The structure of the auxiliary color resist section and the main color resist block is described below using one type of auxiliary color resist block as an example:

[0231] Please refer to Figure 25, which is a schematic diagram of another display panel structure provided in an embodiment of this application. The multiple main color blocks 15 include: a green main color block 15a, a red main color block 15b and a blue main color block 15c. The first auxiliary color block 141a in the auxiliary color block layer 14 is red and the second auxiliary color block 141b is blue.

[0232] In this embodiment, the first auxiliary color resist part 141a and the red main color resist block 15b are manufactured in the same layer and are made of the same material. That is, the red color resist material layer is manufactured by a one-step patterning process in this application embodiment. The part of the red color resist material layer that overlaps with the red light-emitting device 12b1 in the orthographic projection is the red main color resist block 15b, and the other part of the red color resist material layer is the first auxiliary color resist part 141a.

[0233] The red color resist material layer has a third opening K-R1, a fourth opening K-R2, and a first through-hole H1. That is, the structure of the red color resist material layer can be a mesh structure with multiple openings. The orthographic projection of the third opening K-R1 on the driving backplate 11 overlaps with the orthographic projection of the green light-emitting device 12a on the driving backplate 11, so that the light emitted from the green light-emitting device 12a is emitted through the third opening K-R1. The orthographic projection of the fourth opening K-R2 on the driving backplate 11 overlaps with the orthographic projection of the blue light-emitting device 12b2 on the driving backplate 11, so that the light emitted from the blue light-emitting device 12b2 is emitted through the fourth opening K-R2.

[0234] The second auxiliary color resist 141b and the blue main color resist block 15c are manufactured in the same layer and made of the same material. That is, in this embodiment of the application, the blue color resist material layer is manufactured by a one-step patterning process. The part of the blue color resist material layer that overlaps with the blue light-emitting device 12b2 in the orthographic projection is the blue main color resist block 15c, and the other part of the blue color resist material layer is the second auxiliary color resist 141b.

[0235] The blue color resist material layer has a fifth opening K-B1, a sixth opening K-B2, and a second through-hole H2. This means the blue color resist material layer can have a mesh structure with multiple openings. The orthographic projection of the fifth opening K-B1 onto the driving backplate 11 overlaps with the orthographic projection of the red light-emitting device 12b1 onto the driving backplate 11, allowing light emitted from the red light-emitting device 12b1 to exit through the third opening R1. The orthographic projection of the sixth opening K-B2 onto the driving backplate 11 overlaps with the orthographic projection of the green light-emitting device 12a onto the driving backplate 11, allowing light emitted from the green light-emitting device 12a to exit through the fourth opening R2.

[0236] Furthermore, the third opening K-R1 and the sixth opening K-B2 are continuous, and at least a portion of the green main color block 15a is located within the third opening K-R1 and the sixth opening K-B2. For example, all of the green main color block 15a may be located within the third opening K-R1 and the sixth opening K-B2. Alternatively, a portion of the green main color block 15a may be located within the third opening K-R1 and the sixth opening K-B2, while another portion may be located outside the third opening K-R1 and the sixth opening K-B2.

[0237] Furthermore, another portion of the green primary color resist block 15a can overlap with the first auxiliary color resist portion 141a and the second auxiliary color resist portion 141b. Therefore, in the display panel shown in FIG. 25, besides the case where the red and blue color resist material layers are superimposed, other superposition cases can also exist simultaneously. For example, in the area where another portion of the green primary color resist block 15a overlaps with the first auxiliary color resist portion 141a, the red and green color resist material layers are superimposed. According to FIG. 5, this area can also reduce reflectivity and crosstalk. In the area where another portion of the green primary color resist block 15a overlaps with the second auxiliary color resist portion 141b, the red, green, and blue color resist material layers are superimposed. According to FIG. 5, this area can also reduce reflectivity and crosstalk. In the first exemplary embodiment, for the normal display area, to achieve the functions of reducing reflectivity and avoiding crosstalk, the following two cases can be included:

[0238] Referring to Figure 24, in one scenario, a portion of the auxiliary color resist layer 14 is distributed within the light-sensitive display area Q1, while another portion is distributed within the normal display area Q2. The auxiliary color resist layer 14 has multiple first openings K1 corresponding one-to-one with multiple main color resist blocks 15, with at least a portion of the main color resist blocks 15 located within their respective first openings K1. In this way, the display panel does not require a black matrix layer, reducing the amount of mask used.

[0239] In the first case, the auxiliary color resist layer 14 in the normal display area Q2 will be described using four embodiments:

[0240] For the first embodiment, please refer to FIG26. FIG26 is a schematic diagram of another display panel structure provided in this application embodiment. The auxiliary color resist layer 14 distributed in the normal display area Q2 includes: a first auxiliary color resist part 141a and a second auxiliary color resist part 141b. The color of the first auxiliary color resist part 141a is blue, and the color of the second auxiliary color resist part 141b is green. That is, the blue color resist material layer and the green color resist material layer are superimposed.

[0241] For the second embodiment, please refer to Figure 27. Figure 27 is a schematic diagram of another display panel structure provided in this application embodiment. The auxiliary color resist layer 14 distributed in the normal display area Q2 includes: a first auxiliary color resist part 141a and a second auxiliary color resist part 141b. The color of the first auxiliary color resist part 141a is red, and the color of the second auxiliary color resist part 141b is blue. That is, the blue color resist material layer and the red color resist material layer are superimposed.

[0242] For the third embodiment, please refer to Figure 28. Figure 28 is a schematic diagram of another display panel structure provided in this application embodiment. The auxiliary color resist layer 14 distributed in the normal display area Q2 includes: a first auxiliary color resist part 141a and a second auxiliary color resist part 141b. The color of the first auxiliary color resist part 141a is green, and the color of the second auxiliary color resist part 141b is red. That is, the red color resist material layer and the green color resist material layer are superimposed.

[0243] The fourth embodiment is illustrated in Figure 29, which is a schematic diagram of another display panel structure provided in this application embodiment. The auxiliary color resist layer 14 distributed in the normal display area Q2 includes: a first auxiliary color resist portion 141a, a second auxiliary color resist portion 141b, and a third auxiliary color resist portion 141c. The first auxiliary color resist portion 141a is red, the second auxiliary color resist portion 141b is blue, and the third auxiliary color resist portion 141c is green. That is, a red color group material layer, a blue color resist material layer, and a green color resist material layer are stacked.

[0244] In the above four embodiments, the stacking order of the multilayer auxiliary color resist can also be interchanged. For details, please refer to the structure of the auxiliary color resist layer in the light-sensitive display area, which will not be elaborated here.

[0245] In another scenario, please refer to Figure 30, which is a schematic diagram of another display panel structure provided in an embodiment of this application. The auxiliary color resist layer 14 is only distributed within the photosensitive display area Q1. The display panel further includes a black matrix layer BM distributed within the normal display area Q2, located on the side of the encapsulation layer 13 opposite to the driving backplate 11. The auxiliary color resist layer 14 has multiple first openings K1, each corresponding to a plurality of main color resist blocks 15 distributed within the photosensitive display area Q1. At least a portion of the main color resist blocks 15 distributed within the photosensitive display area Q1 is located within the corresponding first opening K1. The black matrix layer BM has multiple second openings K2, each corresponding to a plurality of main color resist blocks 15 distributed within the normal display area Q2. At least a portion of the main color resist blocks 15 distributed within the normal display area Q2 is located within the corresponding second opening K2.

[0246] In the second case, an auxiliary color resist layer 14 in the normal display area Q2 will be described with reference to an embodiment. Please refer to FIG31, which is a schematic diagram of another display panel structure provided in an embodiment of this application. The black matrix layer BM has a plurality of second openings K2, and the plurality of second openings K2 correspond one-to-one with a plurality of main color resist blocks 15 distributed in the normal display area Q2. A portion of the main color resist blocks 15 distributed in the normal display area Q2 is located in the corresponding second opening K2, and the other portion overlaps with the black matrix layer BM, which can prevent the main color resist blocks 15 from peeling off.

[0247] It should be noted that the structure of the main color block 15 and the black matrix layer BM in Figures 24 and 30 can also be applied to other embodiments described above, and the embodiments of this application will not be elaborated here.

[0248] In a second exemplary embodiment, a light transmittance adjustment layer may be provided in the display panel, the light transmittance adjustment layer having selective transmittance to at least two colors of light.

[0249] Please refer to Figure 32, which is a schematic diagram of another display panel structure provided in an embodiment of this application. Multiple light-emitting devices 12 are used to emit at least two colors of light. The display panel also includes a light transmission adjustment layer 16, which is located on the side of the auxiliary color resist layer 14 away from the driving back plate 11. The light transmission adjustment layer 16 is used to transmit at least two colors of light and block other colors of light besides the at least two colors of light.

[0250] For example, the transmittance characteristics of a light-transmitting adjustment layer 16 are shown in Figure 33. Figure 33 is a transmittance spectrum of a light-transmitting adjustment layer provided in an embodiment of this application. The light-transmitting adjustment layer 16 can transmit red, blue, and green light, and can block light other than these three colors from passing through, that is, the light-transmitting adjustment layer 16 has selective transmittance. Therefore, the light-transmitting adjustment layer 16 can achieve a filtering effect on red, green, and blue light-emitting devices, thereby ensuring good color purity of the display panel during image display. Furthermore, the light-transmitting adjustment layer 16 can block light other than these three colors from passing through, and when ambient light enters the display panel, it can also be partially blocked by the light-transmitting adjustment layer 16, thereby reducing reflectivity. For example, the transmittance range of the light-transmitting adjustment layer 16 can be 50%-90%, and the thickness range of the light-transmitting adjustment layer 16 can be 2 micrometers-5 micrometers.

[0251] In this application, the light transmittance adjustment layer 16 also has another aspect: it can transmit both visible and infrared light, and it does not have selective transmittance in the visible light band (380-780nm). This type of non-selective transmittance adjustment layer 16 has a lower cost. Furthermore, the transmittance range of this light transmittance adjustment layer 16 can be 50%-90%, ensuring that it has a certain transmittance for the light emitted by the light-emitting device 12 while absorbing some ambient light, thereby reducing reflectivity.

[0252] In this design, the orthographic projection of multiple light-emitting devices 12 onto the driving backplate 11 lies within the orthographic projection of the light-transmitting adjustment layer 16 onto the driving backplate 11. In this way, the light-transmitting adjustment layer 16 can filter the light emitted by the multiple light-emitting devices 12, thereby improving the color purity of the display panel. Furthermore, compared to the need for three patterning processes to form multiple main color blocks, since the light-transmitting adjustment layer 16 is a single-layer film, it can be formed in a single patterning process, thus improving production efficiency and saving costs.

[0253] In a second exemplary embodiment, for the normal display area, to achieve the functions of reducing reflectivity and avoiding crosstalk, the following two cases may be included:

[0254] Referring to Figure 32, in one scenario, a portion of the auxiliary color resist layer 14 is distributed within the light-sensitive display area Q1, while another portion is distributed within the normal display area Q2. The auxiliary color resist layer 14 has multiple first openings K1 corresponding one-to-one with the multiple light-emitting devices 12, and at least a portion of the main color resist blocks 15 are located within the corresponding first openings K1. In this way, the display panel does not require a black matrix layer, reducing the amount of mask used.

[0255] In another scenario, please refer to Figure 34, which is a schematic diagram of another display panel structure provided in an embodiment of this application. The auxiliary color resist layer 14 is only distributed within the photosensitive display area Q1. The display panel further includes a black matrix layer BM distributed within the normal display area Q2, located on the side of the encapsulation layer 13 opposite to the driving backplate 11. The auxiliary color resist layer 14 has multiple first openings K1, each corresponding to a plurality of light-emitting devices 12 distributed within the photosensitive display area Q1. At least a portion of the light-transmitting adjustment layers 16 distributed within the photosensitive display area Q1 is located within the corresponding first opening K1. The black matrix layer BM has multiple second openings K2, each corresponding to a plurality of light-emitting devices 12 distributed within the normal display area Q2. At least a portion of the light-transmitting adjustment layers 16 distributed within the normal display area Q2 is located within the corresponding second opening K2.

[0256] It should be noted that the structures of the light transmission adjustment layer 16 and the black matrix layer BM in Figures 32 and 34 can also be applied to other embodiments described above, and the embodiments of this application will not be elaborated here.

[0257] This application embodiment provides another display panel. Please refer to FIG35, which is a schematic diagram of the structure of another display panel provided in this application embodiment. The display panel further includes a pixel definition layer 17, which is located between the driving backplane 11 and the encapsulation layer 13. The pixel definition layer 17 has a plurality of pixel openings K3, and the plurality of pixel openings K3 correspond one-to-one with a plurality of light-emitting devices 12. At least a portion of the light-emitting devices 12 are located within the corresponding pixel openings K3. The pixel definition layer 17 can be used to define the positions of the plurality of light-emitting devices 12 in the display panel on the driving backplane 11 to avoid crosstalk.

[0258] Optionally, the pixel definition layer 17 has the property of absorbing visible light. Within the light-sensing display area Q1, the pixel definition layer 17 has an auxiliary light-passing hole h corresponding to the light-passing hole H. The orthographic projection of the auxiliary light-passing hole h on the driving back plate 11 overlaps with the orthographic projection of the light-passing hole H on the driving back plate 11. By setting the pixel definition layer 17 with light-absorbing properties, the pixel definition layer 17 can reduce the reflectivity of light incident from outside the display panel, thereby improving the contrast. Since the pixel definition layer 17 cannot transmit visible light, setting the auxiliary light-passing hole h can improve the transmittance of the light-sensing display area Q1, ensuring the normal operation of the light-sensing element.

[0259] In addition, when the photosensitive band of the photosensitive element is infrared light, since the pixel definition layer 17 can transmit infrared light, the pixel definition layer 17 may not need to be provided with an auxiliary light-transmitting hole h.

[0260] Furthermore, the pixel definition layer 17 provided in this application embodiment may also include a transparent material, that is, the pixel definition layer 17 may not have light absorption properties, so the pixel definition layer 17 may not have an auxiliary light-transmitting hole h.

[0261] This application does not limit the relative sizes of the auxiliary light-transmitting aperture h and the light-transmitting aperture H. For example, the size of the auxiliary light-transmitting aperture h can be larger than the size of the light-transmitting aperture H, or the size of the auxiliary light-transmitting aperture h can be smaller than the size of the light-transmitting aperture H, or the size of the auxiliary light-transmitting aperture h can be equal to the size of the light-transmitting aperture H. Furthermore, at least one of these three cases can be included in the same display panel. For example, the arrangement in different areas can be the same to facilitate manufacturing. The arrangement in different areas can also be different to adapt to the needs of different areas.

[0262] Optionally, the display panel may further include a touch layer 18, located between the encapsulation layer 13 and the auxiliary color resist layer 14. In this application, a flexible multilayer on-cell (FMLOC) technology can be employed, i.e., a technique for fabricating the touch layer 18 on the encapsulation layer 13 using a patterning process, thereby achieving integrated display and touch functionality. The touch layer 18 may include touch electrodes and a touch insulating layer. For example, the touch electrodes may include a self-capacitive capacitor structure or a mutual-capacitive capacitor structure. When a user's finger contacts the touch electrodes, the capacitance value in the self-capacitive capacitor structure or the mutual-capacitive capacitor structure changes to determine the location of the touch, thus enabling the display panel to perform touch functionality.

[0263] It should be noted that the structure of the pixel definition layer 17 and the touch layer 18 in Figure 35 can also be applied to other embodiments described above, and the embodiments of this application will not be elaborated here.

[0264] In this application, the auxiliary color resist layer in the photosensitive display area may not have a light-transmitting hole. The following example uses the case where the auxiliary color resist layer includes two auxiliary color resist sections. Please refer to Figure 36, which is a schematic diagram of another display panel structure provided in an embodiment of this application. The display panel includes: a driving backplate 11, a light-emitting device 12, an encapsulation layer 13, and an auxiliary color resist layer 14. The auxiliary color resist layer 14 includes: a first auxiliary color resist section 141a and a second auxiliary color resist section 141b stacked along a direction away from the encapsulation layer 13. The auxiliary color resist layer 14 distributed in the photosensitive display area Q1 does not have a light-transmitting hole.

[0265] Based on the transmission spectrum shown in Figure 5, it can be seen that when the colors of the first auxiliary color resist layer 141a and the second auxiliary color resist layer 141b are blue and red, respectively; or when the colors of the first auxiliary color resist layer 141a and the second auxiliary color resist layer 141b are red and green, respectively; or when the colors of the first auxiliary color resist layer 141a and the second auxiliary color resist layer 141b are blue and green, respectively, the auxiliary color resist layer 14 exhibits extremely low transmittance for visible light and high transmittance for infrared light. Therefore, when the photosensitive band of the mounted photosensitive element is the infrared band, the auxiliary color resist layer 14 can meet the light transmission requirements of the photosensitive element without providing a light-passing hole, thereby simplifying the manufacturing process of the display panel.

[0266] Furthermore, when the auxiliary color resist layer comprises three auxiliary color resist sections, as shown in Figure 5, it can be seen that the auxiliary color resist layer also exhibits extremely low transmittance for visible light and high transmittance for infrared light. Therefore, when the photosensitive band of the mounted photosensitive element is the infrared band, the auxiliary color resist layer formed by stacking three auxiliary color resist sections does not need to have a light-passing hole, thus satisfying the light transmission requirements of the photosensitive element and simplifying the manufacturing process of the display panel.

[0267] It should be noted that the embodiments of this application do not limit the shape and size of the light-emitting device, the second opening of the black matrix layer, and the pixel opening of the pixel definition layer. For example, their shapes can be inverted ellipses, circles, ellipses, polygons, etc. Furthermore, their sizes can be the same or different.

[0268] The embodiments of this application do not limit the arrangement of the light-emitting devices. For example, the arrangement of the light-emitting devices can be diamond arrangement, magic arrangement, Real RGB arrangement, RGB Pentile arrangement, etc.

[0269] In summary, this application provides a display panel with an auxiliary color resist layer. This auxiliary color resist layer includes at least two stacked auxiliary color resist portions, each of different colors. Thus, the auxiliary color resist layer can block at least three colors of light. For the portion of the auxiliary color resist layer distributed within the photosensitive display area, by providing a light-transmitting hole penetrating at least one auxiliary color resist portion, it can be ensured that the auxiliary color resist layer allows light of a specific wavelength to pass through. Furthermore, by adjusting the penetration of the light-transmitting hole, this specific wavelength can be controlled, thereby improving the matching between the wavelength of light transmitted to the photosensitive display area and the photosensitive wavelength of the photosensitive element, enabling the photosensitive element to function normally.

[0270] On the other hand, this application also provides a display device. Please refer to FIG37, which is a schematic diagram of the structure of a display device provided in this application embodiment. The display device 20 includes: a light-sensing element 21 and a display panel 10 provided in any of the above embodiments. The light-sensing element 21 is distributed on the back side of the display panel 10, and the light-receiving surface of the light-sensing element 21 faces the light-sensing display area Q1. In this way, external light can pass through the light-sensing display area Q1 and be received by the light-sensing element 21.

[0271] Since the display device 20 includes the display panel 10 provided in the above embodiment, the display device 20 can also have a similar effect, that is, it can improve the matching between the wavelength of light that can be transmitted through the light-sensitive display area Q1 and the light-sensitive wavelength of the light-sensitive element 21.

Similarly, "at least one of A, B, and C" indicates that seven relationships can exist, representing: A existing alone, B existing alone, C existing alone, A and B existing simultaneously, A and C existing simultaneously, C and B existing simultaneously, and A, B, and C existing simultaneously.
