Description

Technical Field

[0001] This application relates to the field of display technology, and more specifically, to a color temperature detection method, a display panel, and an electronic device. Background Technology

[0002] With the continuous development of electronic device display technology, users' demands for shooting effects and display visual experience are increasing. Currently, smartphones and other electronic devices are typically equipped with color temperature sensors to detect the color temperature and illuminance of ambient light, enabling the device to automatically adjust the brightness and color temperature of the display according to environmental conditions. This technology not only helps improve the white balance accuracy when taking photos but also optimizes display effects and enhances user viewing comfort in various lighting environments.

[0003] To further increase the screen-to-body ratio and achieve a full-screen display effect, existing technologies have proposed a design scheme that integrates the color temperature sensor into the display area of ​​the display panel. However, this scheme faces a major problem: when the device displays images, the color temperature sensor not only receives ambient light from outside the display panel but also interference light emitted by the light-emitting elements within the display panel and reflected within the panel. This interference light reflected from within the panel severely interferes with the color temperature sensor's detection of the color temperature of pure ambient light, thus failing to accurately reflect the color temperature of the ambient light and ultimately causing a significant decrease in the accuracy of color temperature detection.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] As described in the background section, with the continuous development of electronic device display technology, users' demands for shooting effects and display visual experience are increasing. Currently, smartphones and other electronic devices are typically equipped with color temperature sensors to detect the color temperature and illuminance of ambient light, enabling the device to automatically adjust the brightness and color temperature of the display according to environmental conditions. This technology not only helps improve the white balance accuracy when taking photos but also optimizes display effects and enhances user viewing comfort in various lighting environments.

[0044] To further increase the screen-to-body ratio and achieve a full-screen display effect, existing technologies have proposed a design scheme that integrates the color temperature sensor into the display area of ​​the display panel. However, this scheme faces a major problem: when the device displays images, the color temperature sensor not only receives ambient light from outside the display panel but also interference light emitted by the light-emitting elements within the display panel and reflected within the panel. This interference light reflected from within the panel severely interferes with the color temperature sensor's detection of the color temperature of pure ambient light, thus failing to accurately reflect the color temperature of the ambient light and ultimately causing a significant decrease in the accuracy of color temperature detection.

[0045] Based on this, this application provides a color temperature detection method, a display panel, and an electronic device, which effectively solves the technical problems existing in the prior art. It removes the interference light components collected by the corresponding interference light sensor from the light data collected by the color temperature sensor, reduces the color temperature detection error of the color temperature sensor, and thus obtains more accurate color temperature data of the ambient light outside the display panel, thereby improving the accuracy of color temperature detection.

[0046] To achieve the above objectives, the technical solution provided in this application is as follows, in specific combination with... Figures 1 to 20 The technical solution provided in this application is described in detail.

[0047] Combination Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of this application (the dashed arrows indicate the transmission direction of the interfering light). Figure 2This is a schematic diagram of a sensor distribution provided in an embodiment of this application. The display area of ​​the display panel 10 provided in this embodiment includes: a substrate 100; a light-emitting structure layer 200 located on one side of the substrate 100, the light-emitting structure layer 200 including a plurality of light-emitting elements 201; a light-filtering structure layer 300 located on the side of the light-emitting structure layer 200 away from the substrate 100, the light-filtering structure layer 300 including a plurality of filter portions 301, at least one light-transmitting portion 302, and a light-shielding portion 303, the light-shielding portion 303 being disposed around the filter portions 301 and the light-transmitting portion 302; in the direction perpendicular to the plane of the display panel 10, one filter portion 301 at least partially overlaps with one light-emitting element 201; and at least one color temperature sensor 11 located between the substrate 100 and the light-filtering structure layer 300; in the direction perpendicular to the plane of the display panel 10, the color temperature sensor 11 at least partially overlaps with the light-transmitting portion 302. At least one interference light sensor 12 is located between the substrate 100 and the light-shielding portion 303; in the direction parallel to the plane of the display panel, the interference light sensor 12 is distributed in the direction surrounding the color temperature sensor 11.

[0048] As can be seen from the above, in the technical solution provided by this application embodiment, at least one interference light sensor 12 is arranged around the color temperature sensor 11. When detecting the color temperature of ambient light outside the display panel 10, the color temperature sensor 11 can collect the ambient light signal outside the display panel 10, while the interference light sensor 12 can collect the interference light signal reflected from inside the display panel 10 near the color temperature sensor 11. Furthermore, by removing the interference light component collected by the interference light sensor 12 from the light data collected by the color temperature sensor 11, the color temperature detection error of the color temperature sensor 11 can be reduced, thereby obtaining more accurate color temperature data of ambient light outside the display panel 10 and improving the accuracy of color temperature detection.

[0049] Continue as Figure 1As shown, the substrate 100 provided in this embodiment includes a substrate 110 and a driving array layer 120 stacked sequentially. The driving array layer 120 refers to a structural layer forming related lines such as driving circuits and pixel circuits. In some embodiments, the driving array layer 120 includes a semiconductor layer 121, which includes an active region constituting a transistor; a gate metal layer 122 located on the side of the semiconductor layer 121 away from the substrate 110, which includes a gate constituting a transistor; and a source / drain metal layer 123 located on the side of the gate metal layer 122 away from the substrate 110, which includes a source and a drain constituting a transistor. An insulating layer is disposed between adjacent layers of the semiconductor layer 121, the gate metal layer 122, and the source / drain metal layer 123. To improve the performance of the driving array layer 120 and the effective wiring space, the driving array layer 120 may further include a light-shielding metal layer 124 located between the semiconductor layer 121 and the substrate 110, and an insulating layer is disposed between the semiconductor layer 121 and the light-shielding metal layer 124. The light-shielding metal layer 124 may include some light-shielding metal blocks. In the direction perpendicular to the plane of the display panel 10 (i.e., the thickness direction of the display panel 10, i.e., the direction in which the substrate 100 and the light-emitting structure layer 200 point to each other), the light-shielding metal blocks may at least partially overlap with the active area of ​​the semiconductor layer 121, thereby blocking stray light from entering the active area. In addition, the light-shielding metal layer 124 may also be provided with some auxiliary lines, etc., to improve the wiring space of the panel. The display panel 10 may further include a capacitor metal layer 125 located between the gate metal layer 122 and the source / drain metal layer 123, and an insulating layer is disposed between the gate metal layer 122 and the capacitor metal layer 125, and between the capacitor metal layer 125 and the source / drain metal layer 123. In addition, the display panel 10 also includes at least one functional metal layer 126 located on the side of the source / drain metal layer 123 away from the substrate 110. The functional metal layer 126 is used to fabricate some traces and transition electrodes, etc. An insulating layer is provided between the functional metal layer 126 and the source / drain metal layer 123. When the panel includes at least two functional metal layers 126, an insulating layer is also provided between adjacent functional metal layers 126.

[0050] Figure 1 The illustration shows a case where the transistors included in the display panel 10 are top-gate transistors. However, the transistors in the display panel 10 provided in this embodiment can also be bottom-gate transistors. For example... Figure 3 As shown, this is a schematic diagram of another display panel structure provided in an embodiment of this application. The driving array layer 120 also includes a semiconductor layer 121, a gate metal layer 122, and a source / drain metal layer 123, and... Figure 1 The stacking order shown is different. Figure 2The semiconductor layer 121 shown is located on the side of the gate metal layer 122 facing away from the substrate 110. Similarly, an insulating layer is provided between adjacent layers of the semiconductor layer 121, the gate metal layer 122, and the source / drain metal layer 123. Furthermore, when the transistors included in the display panel 10 provided in this embodiment are bottom-gate transistors, the display panel 10 may also include at least one of the following: a light-shielding metal layer 124, a capacitor metal layer 125, and a functional metal layer 126. In this case, the light-shielding metal layer 124 is located between the gate metal layer 122 and the substrate 110. The capacitor metal layer 125 may be located between the source / drain metal layer 123 and the semiconductor layer 121, or the capacitor metal layer 125 may also be located between the gate metal layer 122 and the semiconductor layer 121. This application does not impose specific limitations on this, and an insulating layer is provided between each conductive layer for insulation isolation.

[0051] The light-emitting structure layer 200 provided in this embodiment includes a plurality of light-emitting elements 201, each of which may consist of at least an anode, a light-emitting unit, and a cathode. The light-emitting structure layer 200 includes an anode layer 210, a light-emitting layer 220, a cathode layer 230, and a pixel definition layer 240. The anode layer 210 forms the anode of the light-emitting element 201. The pixel definition layer 240 is located on the side of the anode layer 210 facing away from the substrate 100, and includes a plurality of pixel openings that expose at least a portion of the anode of the light-emitting element 201. The light-emitting layer 220 includes a plurality of light-emitting units located within the pixel openings and in contact with the anode. The cathode layer 230 is located on the side of the light-emitting layer 220 away from the substrate 100. The cathode layer 230 includes the cathode of the light-emitting element 201. The cathode layer 230 can be a whole electrode covering the exposed surface of the pixel definition layer 240 and the light-emitting layer 220 away from the substrate 100, and all light-emitting elements 201 share the same cathode. Alternatively, the cathode layer 230 can also include multiple cathode blocks, which are located in the pixel opening and in contact with the light-emitting unit. All cathode blocks are connected by lines. This application does not impose specific limitations on this.

[0052] An encapsulation structure layer is disposed on the light-emitting structure layer 200. The encapsulation structure layer can be a stacked encapsulation type of inorganic layer-organic layer-inorganic layer, or it can be other encapsulation types, which are not specifically limited in this application. The light-filtering structure layer 300 provided in this embodiment is disposed on the side of the encapsulation structure layer away from the substrate 100. The light-filtering structure layer 300 includes a plurality of light-filtering portions 301, at least one light-transmitting portion 302, and a light-shielding portion 303, which is disposed around the light-filtering portion 301 and the light-transmitting portion 302. In the direction perpendicular to the plane of the display panel 10, a light-filtering portion 301 at least partially overlaps with a light-emitting element 201. In some embodiments, the filter structure layer 300 may include a color resist layer 310 and a black matrix layer 320 stacked together. The color resist layer 310 may be located on the side of the black matrix layer 320 facing away from the substrate 100, or the black matrix layer 320 may be located on the side of the color resist layer 310 facing away from the substrate 100; that is, the order in which the color resist layer 310 and the black matrix layer 320 are fabricated is not specifically limited in this application. The filter portion 301 provided in the embodiments of this application may be made of the color resist layer 310, and the light-shielding portion 303 may be made of the black matrix layer 320. When the emission color of at least one light-emitting element 201 is different from the emission color of the other light-emitting elements 201, the filter color of the filter portion 301 corresponding to that light-emitting element 201 is also different from the filter color of the other filter portions 301. When the light-emitting element 201 provided in the embodiments of this application includes a red light-emitting element, a blue light-emitting element, and a green light-emitting element, the filter section 301 corresponding to the red light-emitting element is a red light filter section, the filter section 301 corresponding to the blue light-emitting element is a blue light filter section, and the filter section 301 corresponding to the green light-emitting element is a green light filter section. Optionally, in the display panel 10 provided in the embodiments of this application, a touch structure layer may also be provided between the encapsulation structure layer and the filter structure layer 300, so that the display panel 10 integrates touch functionality. This application does not impose specific limitations on this.

[0053] The color temperature sensor 11 and interference light sensor 12 provided in this application embodiment are located between the substrate 100 and the filter structure layer 300. In some embodiments, the color temperature sensor 11 and interference light sensor 12 provided in this application embodiment may be located between the substrate 100 and the light-emitting structure layer 200; that is, the substrate 100 provided in this application embodiment includes: a substrate 110; a driving array layer 120, the driving array layer 120 being located between the substrate 110 and the light-emitting structure layer 200; at least one of the color temperature sensor 11 and interference light sensor 12 is located between the driving array layer 120 and the light-emitting structure layer 200; in the direction perpendicular to the plane of the display panel 10, the overlapping area of ​​the light-emitting structure layer 200 with the color temperature sensor 11 and interference light sensor 12 has a light channel. Based on this, the light-emitting structure layer 200 provided in this application embodiment includes: a pixel definition layer 240, which includes a plurality of pixel openings and at least one sensing opening 241; a light-emitting element 201 is located at the pixel opening; and in the direction perpendicular to the plane of the display panel 10, at least one of the color temperature sensor 11 and the interference light sensor 12 overlaps at least partially with the sensing opening 241, so that the overlapping area of ​​the light-emitting structure layer 200 with the color temperature sensor 11 and the interference light sensor 12 has a light channel, the color temperature sensor 11 can collect ambient light through the light channel, and the interference light can be transmitted to the color temperature sensor 11 and the interference light sensor 12 through different light channels.

[0054] Specifically, such as Figure 1 and Figure 3As shown, a planarization layer 400 is disposed between the substrate 100 and the anode layer 210. The color temperature sensor 11 and the interference light sensor 12 are both located between the substrate 100 and the planarization layer 400. The pixel definition layer 240 includes a sensing opening 241. In the direction perpendicular to the plane of the display panel 10, the color temperature sensor 11 is overlapped with the corresponding sensing opening 241 so that the color temperature sensor 11 forms a light channel with the light-transmitting part 302 through the corresponding sensing opening 241. The color temperature sensor 11 can collect ambient light outside the display panel 10 through the light channel. In the direction perpendicular to the plane of the display panel 10, the interference light sensor 12 is overlapped with the corresponding sensing opening 241 so that the interference light sensor 12 can collect interference light reflected by the light-shielding part 303 through the corresponding sensing opening 241. Furthermore, in this embodiment, the interference light sensor 12 is disposed between the light-shielding part 303 and the substrate 100, thereby preventing the interference light sensor 12 from collecting ambient light outside the display panel 10. The interference light sensor 12 can only collect interference light reflected from inside the display panel 10. When the display panel 10 displays an image, some of the light emitted by the light-emitting element 201 is reflected by the light-shielding part 303 to form interference light. The reflected interference light can be transmitted to the interference light sensor 12 for collection, and also to the color temperature sensor 11 for collection (the data collected by the color temperature sensor 11 is the sum of the ambient light component and the interference light component). In this embodiment, at least one interference light sensor 12 is disposed near the color temperature sensor 11, so that the interference light components collected by the color temperature sensor 11 and the interference light sensor 12 are basically the same. Therefore, by removing the interference light component collected by the interference light sensor 12 from the light data collected by the color temperature sensor 11, the color temperature detection error of the color temperature sensor 11 can be reduced, thereby obtaining more accurate color temperature data of the ambient light outside the display panel 10 and improving the accuracy of color temperature detection.

[0055] like Figure 2 As shown in the embodiment of this application, an interference light sensor 12 is provided in the direction surrounding the color temperature sensor 11, which is equivalent to providing an interference light sensor 12 near the side of the color temperature sensor 11. Figure 4The diagram shown illustrates another distribution of sensors and light-emitting elements provided in this embodiment. In this embodiment, at least two interference light sensors 12 are arranged around the color temperature sensor 11, effectively distributing multiple interference light sensors 12 near the color temperature sensor 11. The interference light component removed from the light data collected by the color temperature sensor 11 can be the average value of the data collected by all the interference light sensors 12 corresponding to the color temperature sensor 11, or it can be a data value obtained using other algorithms; this application does not impose specific limitations on this. In some embodiments, when the color temperature sensor 11 corresponds to multiple interference light sensors 12, the multiple interference light sensors 12 can be uniformly distributed along the direction surrounding the color temperature sensor 11.

[0056] In some embodiments, the color temperature sensor 11 included in the display panel 10 provided in this application can collect the full-spectrum light of the ambient light of the display panel 10. (Reference) Figure 5 The diagram shown illustrates the structure of another display panel according to an embodiment of this application. The light-transmitting portion 302 provided in this embodiment includes a first light-transmitting portion 3021, which transmits light across the entire wavelength range. The color temperature sensor 11 includes a first color temperature sensor 111. In the direction perpendicular to the plane of the display panel 10, the first color temperature sensor 111 and the first light-transmitting portion 3021 at least partially overlap. The first color temperature sensor 111 collects the full wavelength range of ambient light outside the display panel 10 through the light channel formed between it and the first light-transmitting portion 3021, thereby achieving the purpose of adjusting the panel display, etc., based on the color temperature of the full wavelength range of light.

[0057] Optionally, the first light-transmitting portion 3021 provided in this application embodiment includes a colorless structural layer. This colorless structural layer can transmit ambient light across the entire wavelength range for collection by the first color temperature sensor 111. During the fabrication of the display panel 10, the colorless structural layer provided in this application embodiment can be a material layer separately fabricated at the first light-transmitting portion 3021. Specifically, a first opening is obtained by drilling a hole in the area of ​​the filter structural layer 300 corresponding to the first light-transmitting portion 3021, and then colorless material is filled into the first opening to form the colorless structural layer. In some other embodiments, the colorless structural layer provided in this application embodiment can also be fabricated using existing material layers of the display panel 10; see details below. Figure 6The diagram shows a structural schematic of another display panel provided in this application embodiment. The display panel 10 provided in this application embodiment includes: a cover plate 510, which is located on the side of the light filter structure layer 300 away from the substrate 100; and an adhesive layer 520, which is located between the cover plate 510 and the light filter structure layer 300. The colorless structure layer is a portion of the adhesive layer 520. In other words, in the manufacturing process of the display panel 10 provided in this application embodiment, after a first opening is obtained by drilling a hole in the area of ​​the light filter structure layer 300 corresponding to the first light-transmitting portion 3021, the adhesive layer 520 is formed on the light filter structure layer 300. The material of the adhesive layer 520 fills the first opening to form a colorless structure layer, thus eliminating the need to prepare the material separately to prepare this layer, simplifying the panel manufacturing process and reducing the panel manufacturing cost.

[0058] In some embodiments, the color temperature sensor 11 included in the display panel 10 provided in this application can also collect light of a specific wavelength band in the ambient light of the display panel 10. (See reference...) Figure 7 The diagram shown is a structural schematic of another display panel provided in this application embodiment. The light-transmitting portion 302 provided in this application embodiment includes a second light-transmitting portion 3022, which transmits light of a set color. The color temperature sensor 11 includes a second color temperature sensor 112. In the direction perpendicular to the plane of the display panel 10, the second color temperature sensor 112 and the second light-transmitting portion 3022 at least partially overlap. The second color temperature sensor 112 collects a specific segment of ambient light from the display panel 10 through the light channel formed between it and the second light-transmitting portion 3022, thereby achieving the purpose of adjusting the panel display, etc., based on the color temperature of the specific color light.

[0059] Optionally, at least one second light-transmitting portion 3022 provided in this application embodiment is a red light-transmitting portion for transmitting red light, a green light-transmitting portion for transmitting green light, or a blue light-transmitting portion for transmitting blue light. In some embodiments, the display panel 10 provided in this application embodiment includes all color temperature sensors 11, including a red light color temperature sensor for collecting red light, a green light color temperature sensor for collecting green light, and a blue light color temperature sensor for collecting blue light. Thus, all second light-transmitting portions 3022 of the display panel 10 include a red light-transmitting portion corresponding to the red light color temperature sensor, a green light-transmitting portion corresponding to the green light color temperature sensor, and a blue light-transmitting portion corresponding to the blue light color temperature sensor. By collecting the corresponding color temperature components of red, green, and blue light in ambient light, the purpose of more refined and precise adjustment of the panel display can be achieved.

[0060] The second light-transmitting portion 3022 provided in this application embodiment can be a separately prepared material layer; that is, during the preparation of the display panel 10, the filter structure layer 300 is perforated in the area corresponding to the second light-transmitting portion 3022 to obtain a second opening, and then material is filled at the second opening to form the second light-transmitting portion 3022. In some other embodiments, the second light-transmitting portion 3022 provided in this application embodiment can also be prepared using the original material layer of the display panel 10; see details below. Figure 8 The diagram shown is a structural schematic of another display panel provided in this application embodiment. The light filter structure layer 300 provided in this application embodiment includes a color resist layer 310, and the second light-transmitting part 3022 is a part of the structure layer of the color resist layer 310. In other words, during the fabrication process of the display panel 10 provided in this application embodiment, if a color resist layer 310 is fabricated first and then a black matrix layer 320 is fabricated, while the color resist layer 310 is used to fabricate the light filter portion 301, a color resist material of the corresponding color is formed in the corresponding area of ​​the second light-transmitting portion 3022. Then, the black matrix layer 320 is fabricated to form a light-shielding portion 303 surrounding the light filter portion 301 and the light-transmitting portion 302. Alternatively, when the black matrix layer 320 is fabricated first and then the color resist layer 310 is fabricated, a light filter opening and a second opening are formed on the black matrix layer 320. Then, the color resist layer 310 is used to fill the light filter opening to form the light filter portion 301, and the color resist layer 310 is used to fill the second opening to form the second light-transmitting portion 3022. The remaining part of the black matrix layer 320 is the light-shielding portion 303.

[0061] It should be noted that the display panel 10 provided in this application embodiment may only include a first color temperature sensor 111 and a first light-transmitting part 3021; ​​or, the display panel 10 provided in this application embodiment may only include a second color temperature sensor 112 and a second light-transmitting part 3022, and all the second color temperature sensors 112 may be blue light color temperature sensors, or all of them may be red light color temperature sensors, or all of them may be green light color temperature sensors, and correspondingly, all the second light-transmitting parts 3022 are light-transmitting parts of the color corresponding to the color temperature sensor 11; or, the display panel provided in this application embodiment... The panel 10 may include only the second color temperature sensor 112 and the second light-transmitting part 3022. All the second color temperature sensors 112 may include a combination of at least two of the following: blue light color temperature sensor, red light color temperature sensor, and green light color temperature sensor. Correspondingly, all the second light-transmitting parts 3022 are light-transmitting parts corresponding to the color of the color temperature sensor 11. Alternatively, the display panel 10 provided in this application embodiment may include the first color temperature sensor 111 and the first light-transmitting part 3021, as well as the second color temperature sensor 112 and the second light-transmitting part 3022. This application does not impose specific limitations on this. The display panel 10 provided in this application embodiment allows for the selection of different color temperature sensors 11 and corresponding light-transmitting parts 302 according to panel requirements. This enables the selection of different color temperature data to adjust the panel, achieving further refined and precise adjustments to panel display and other functions, and expanding the panel's applicability.

[0062] In one embodiment, the display area AA provided in this application includes at least one photosensitive area A1. The photosensitive area A1 is provided with at least one first light-transmitting portion 3021 and at least one second light-transmitting portion 3022. When the photosensitive area A1 includes at least two second light-transmitting portions 3022, the set color light transmitted through at least one second light-transmitting portion 3022 is different from the set color light transmitted through the other second light-transmitting portions 3022. Since the light-transmitting portions 302 are correspondingly arranged with the color temperature sensor 11, the distribution of the light-transmitting portions 302 is the same as the distribution of the color temperature sensor 11; see details below. Figure 9The diagram shown is a schematic representation of the distribution of another sensor and light-emitting element provided in this application embodiment. The display area AA provided in this application embodiment includes at least one photosensitive area A1. At least one first light-transmitting part 3021 and at least one second light-transmitting part 3022 are provided in the photosensitive area A1, which is equivalent to providing at least one first color temperature sensor 111 and at least one second color temperature sensor 112 in the photosensitive area A1. The first color temperature sensor 111 collects light of the entire wavelength range in the ambient light, while the second color temperature sensor 112 collects light of a set wavelength range (i.e., light of a set color) in the ambient light. Then, by combining and analyzing the different data collected by the first color temperature sensor 111 and the second color temperature sensor 112, the corresponding color temperature data is selected to adjust the panel according to the panel requirements, so as to achieve the purpose of more refined and precise adjustment of the panel display and other functions. Furthermore, when the photosensitive area A1 includes at least two second light-transmitting portions 3022, the set color light transmitted through at least one second light-transmitting portion 3022 is different from the set color light transmitted through the other second light-transmitting portions 3022; that is, when at least two second color temperature sensors 112 are provided in the photosensitive area A1, the set color light collected by at least one second color temperature sensor 112 is different from the set color light collected by the other second color temperature sensors 112, further expanding the range of ambient light color temperature data selection, such as... Figure 9 The photosensitive area A1 shown in the diagram includes a red light color temperature sensor 1121 and a green light color temperature sensor 1122.

[0063] In some other embodiments, the photosensitive area A1 may further include a red light color temperature sensor 1121 and a blue light color temperature sensor 1123, or the photosensitive area A1 may further include a blue light color temperature sensor 1123 and a green light color temperature sensor 1122. Further, refer to... Figure 10The diagram shown is a schematic diagram of the distribution of another sensor and light-emitting element provided in the embodiment of this application. When the photosensitive area A1 provided in the embodiment of this application includes both a first color temperature sensor 111 and a second color temperature sensor 112, the second color temperature sensor 112 includes both a red light color temperature sensor 1121, a green light color temperature sensor 1122 and a blue light color temperature sensor 1123. It is understood that the display panel 10 provided in this application embodiment includes a first color temperature sensor 111 and a first light-transmitting part 3021, as well as a second color temperature sensor 112 and a second light-transmitting part 3022. All the second color temperature sensors 112 include a blue light color temperature sensor 1123, a red light color temperature sensor 1121, and a green light color temperature sensor 1122. Since the ambient light transmitted through the red light-transmitting part, the green light-transmitting part, and the blue light-transmitting part cannot completely cover the visible light band (380nm~780nm), some light signals will be lost. Therefore, the ambient light data collected by the light channels of the first light-transmitting part 3021 and the first color temperature sensor 111 can be used to supplement the ambient light color temperature detection effect.

[0064] This application embodiment does not impose specific limitations on the arrangement of the first light-transmitting portion 3021 and the second light-transmitting portion 3022, nor on the arrangement of different photosensitive areas A1. In the photosensitive area A1, the first light-transmitting portion 3021 and the second light-transmitting portion 3022 are arranged in a row direction, a column direction, or an array; and / or, the photosensitive area A1 is arranged in a row direction, a column direction, or an array. That is, based on the premise that all photosensitive areas A1 are arranged in a row direction, a column direction, or an array, all light-transmitting portions 302 in each photosensitive area A1 can be arranged in a row direction, a column direction, or an array. For example... Figure 9 and Figure 10 As shown, in the photosensitive area A1 provided in this embodiment, all color temperature sensors 11, consisting of the first color temperature sensor 111 and the second color temperature sensor 112, are arranged in a row direction, that is, all light-transmitting portions 302, consisting of the first light-transmitting portion 3021 and the second light-transmitting portion 3022, are arranged in a row direction. Or refer to Figure 11 The diagram shown is a schematic diagram of the distribution of another sensor and light-emitting element provided in the embodiment of this application. In the photosensitive area A1 provided in the embodiment of this application, all the color temperature sensors 11, which are composed of the first color temperature sensor 111 and the second color temperature sensor 112, are arranged in a 2×2 array. That is, all the light-transmitting parts 302, which are composed of the first light-transmitting part 3021 and the second light-transmitting part 3022, are arranged in a 2×2 array. This needs to be specifically designed according to the actual application.

[0065] Referring to the schematic diagram of the distribution of any sensor and light-emitting element provided in this application, on the reference plane parallel to the plane where the display panel 10 is located, and in the orthographic projection of the reference plane, the color temperature sensor 11 and / or the interference light sensor 12 are disposed in the gap area formed between adjacent light-emitting elements 201. The color temperature sensor 11 and interference light sensor 12 provided in this application embodiment are arranged in the gap area between adjacent light-emitting elements 201 to avoid the sensors affecting the aperture ratio of the display panel 10, ensuring a high display effect of the display panel 10. The following, with reference to the accompanying drawings, describes in more detail several optimized layout schemes between the color temperature sensor 11, interference light sensor 12, and light-emitting elements 201 when the color temperature sensor 11 and interference light sensor 12 are arranged in the gap area between adjacent light-emitting elements 201 according to the embodiments of this application.

[0066] refer to Figure 12 The diagram shown is a schematic representation of the distribution of a sensor and a light-emitting element according to an embodiment of this application. At least one interference light sensor 12 (illustrated as including one interference light sensor 12) is arranged along the direction surrounding the color temperature sensor 11 in a direction parallel to the plane of the display panel 10. In the color temperature sensor 11 and the at least one interference light sensor 12 surrounding it, the distance between the color temperature sensor 11 and at least one adjacent light-emitting element 201 is the same as the distance between the interference light sensor 12 and an adjacent light-emitting element 201 of the same color. This ensures that the environments of the color temperature sensor 11 and the interference light sensor 12 are essentially the same, resulting in high consistency of the interference light collected by the color temperature sensor 11 and the interference light sensor 12. When the interference light component collected by the interference light sensor 12 is removed from the ambient light data collected by the color temperature sensor 11, the obtained ambient light data is more accurate, improving the accuracy of color temperature detection.

[0067] Furthermore, the spacing between the color temperature sensor 11 and any adjacent light-emitting element 201 provided in this embodiment is the same as the spacing between the interference light sensor 12 and an adjacent light-emitting element 201 with the same emitted color. Continuing as... Figure 12As shown, the display panel 10 provided in this embodiment may include a first light-emitting element 2011, a second light-emitting element 2012, and a third light-emitting element 2013 with different light-emitting colors; in the color temperature sensor 11 and the interference light sensor 12 arranged around it: the distance between the color temperature sensor 11 and the adjacent first light-emitting element 2011 and the distance between the interference light sensor 12 and the adjacent first light-emitting element 2011 are the same as the distance a, the distance between the color temperature sensor 11 and the adjacent second light-emitting element 2012 and the distance between the interference light sensor 12 and the adjacent second light-emitting element 2012 are the same. The spacing between the two light sensors is the same as that between the color temperature sensor 11 and the adjacent third light-emitting element 2013, and the spacing between the interference light sensor 12 and the adjacent third light-emitting element 2013 is the same as that between the two light sensors, which is called spacing c. This further improves the consistency of the environment in which the color temperature sensor 11 and the interference light sensor 12 are located, making the interference light collected by the color temperature sensor 11 and the interference light sensor 12 more consistent. When the interference light component collected by the interference light sensor 12 is removed from the ambient light data collected by the color temperature sensor 11, the obtained ambient light data is more accurate, thus improving the accuracy of color temperature detection.

[0068] It should be noted that the light-emitting elements 201 adjacent to the color temperature sensor 11 and the interference light sensor 12, and emitting the same color, can be the same light-emitting element 201; alternatively, the light-emitting elements 201 adjacent to the color temperature sensor 11 and the interference light sensor 12, and emitting the same color, can be different light-emitting elements 201. Continuing as... Figure 12 As shown, the first light-emitting element 2011 adjacent to the color temperature sensor 11 and the interference light sensor 12 is the same light-emitting element 201, while the second light-emitting element 2012 adjacent to the color temperature sensor 11 and the interference light sensor 12 is a different light-emitting element 201, and the third light-emitting element 2013 adjacent to the color temperature sensor 11 and the interference light sensor 12 is a different light-emitting element 201. This needs to be specifically analyzed based on the specific positions of the color temperature sensor 11 and the interference light sensor 12 in the gap formed by the light-emitting elements 201.

[0069] In some embodiments, the light-emitting element 201 provided in this application includes a first light-emitting element 2011; in the direction parallel to the plane of the display panel 10, and in the color temperature sensor 11 and the interference light sensor 12 disposed around it: on the reference plane parallel to the plane of the display panel 10, and in the orthographic projection of the reference plane, at least one interference light sensor 12 and the color temperature sensor 11 are disposed on one side of the first light-emitting element 2011, and the distance between the interference light sensor 12 and the first light-emitting element 2011 is the same as the distance between the color temperature sensor 11 and the first light-emitting element 2011, thereby improving the consistency of the environment in which the interference light sensor 12 and the color temperature sensor 11 are located. Figure 12As shown, in the first direction X, the color temperature sensor 11 and at least one interference light sensor 12 are respectively located on both sides of the first light-emitting element 2011. That is, the color temperature sensor 11 is disposed on the first side of the first light-emitting element 2011, and the interference light sensor 12 is disposed on the second side of the first light-emitting element 2011. At this time, the first side and the second side are opposite sides of the first light-emitting element 2011. Figure 12 The illustration shows that the color temperature sensor 11 and the interference light sensor 12 are located on opposite sides of the first light-emitting element 2011 in the first direction X. The color temperature sensor 11 and the interference light sensor 12 provided in this embodiment can also be located on opposite sides of the first light-emitting element 2011 in other directions; for example... Figure 13 The diagram shows another distribution of sensors and light-emitting elements provided in this application embodiment. The color temperature sensor 11 is located on one side of the first light-emitting element 2011 in the first direction X, while the interference light sensor 12 is located on one side of the first light-emitting element 2011 in the second direction Y. That is, the color temperature sensor 11 is disposed on the first side of the first light-emitting element 2011, and the interference light sensor 12 is disposed on the second side of the first light-emitting element 2011. In this case, the first side and the second side are opposite sides of the first light-emitting element 2011, and are adjacent sides of the first light-emitting element 2011. The distance between the color temperature sensor 11 and the adjacent first light-emitting element 2011 and the distance between the interference light sensor 12 and the adjacent first light-emitting element 2011 are the same, denoted as distance a. The first direction X and the second direction Y intersect, but this application does not impose specific limitations on this. Optionally, the first direction X and the second direction Y are perpendicular. The first direction X can be the scanning line arrangement direction of the display panel 10, and the second direction Y can be the data line arrangement direction of the display panel 10.

[0070] Continue as Figure 12As shown, the light-emitting element 201 provided in this embodiment further includes a second light-emitting element 2012, and the first light-emitting element 2011 and the second light-emitting element 2012 emit different colors of light. On the reference plane parallel to the plane where the display panel 10 is located, and in the orthographic projection of the reference plane, in the second direction Y, a second light-emitting element 2012 is also correspondingly provided on the same side of the color temperature sensor 11 and the interference light sensor 12, and the first direction X and the second direction Y intersect. Further, the light-emitting element 201 provided in this embodiment also includes a third light-emitting element 2013, and the first light-emitting element 2011, the second light-emitting element 2012 and the third light-emitting element 2013 emit different colors of light. On the reference plane parallel to the plane where the display panel 10 is located, and in the orthographic projection of the reference plane, in the first direction X, a third light-emitting element 2013 is also correspondingly provided on different sides of the color temperature sensor 11 and the interference light sensor 12. Specifically, the distance between the color temperature sensor 11 and the adjacent first light-emitting element 2011 is the same as the distance between the interference light sensor 12 and the adjacent first light-emitting element 2011, which is distance a. The distance between the color temperature sensor 11 and the adjacent second light-emitting element 2012 is the same as the distance between the interference light sensor 12 and the adjacent second light-emitting element 2012, which is distance b. Furthermore, the distance between the color temperature sensor 11 and the adjacent third light-emitting element 2013 is the same as the distance between the interference light sensor 12 and the adjacent third light-emitting element 2013, which is distance c. This further improves the consistency of the environment in which the color temperature sensor 11 and the interference light sensor 12 are located, making the interference light collected by the color temperature sensor 11 and the interference light sensor 12 more consistent. When the interference light component collected by the interference light sensor 12 is removed from the ambient light data collected by the color temperature sensor 11, the obtained ambient light data is more accurate, thus improving the accuracy of color temperature detection.

[0071] Figure 12 and Figure 13 The diagram illustrates a distribution structure where a color temperature sensor 11 is correspondingly provided with an interfering light sensor 12. When at least two interfering light sensors 12 are distributed along the direction surrounding the color temperature sensor 11, all interfering light sensors 12 can be centered on the color temperature sensor 11. (Reference) Figure 14The diagram shows another distribution of sensors and light-emitting elements provided in this application embodiment. At least two interference light sensors 12 are arranged along the direction surrounding the color temperature sensor 11 in a direction parallel to the plane of the display panel 10. Among the color temperature sensor 11 and the interference light sensors 12 arranged around it, the interference light sensors 12 are symmetrically distributed around the color temperature sensor 11 in the reference plane parallel to the plane of the display panel 10, and in the orthographic projection of the reference plane. Simultaneously, the distance between the color temperature sensor 11 and at least one adjacent light-emitting element 201 is the same as the distance between the interference light sensor 12 and an adjacent light-emitting element 201 of the same color. By ensuring that the environments of the color temperature sensor 11 and the interference light sensors 12 are basically consistent, resulting in high consistency of the interference light collected by the color temperature sensor 11 and the interference light sensors 12, more accurate interference light components are obtained through multiple interference light sensors 12. Therefore, when removing the interference light components from the ambient light data collected by the color temperature sensor 11, the obtained ambient light data is more accurate, improving the accuracy of color temperature detection.

[0072] refer to Figure 15The diagram shown is a schematic diagram of the distribution of another sensor and light-emitting element provided in the embodiment of this application. The light-emitting element 201 provided in the embodiment of this application includes a first light-emitting element 2011, a second light-emitting element 2012 and a third light-emitting element 2013 with different light-emitting colors; for example, the first light-emitting element 2011 is a blue light-emitting element, the second light-emitting element 2012 is a green light-emitting element and the third light-emitting element 2013 is a red light-emitting element. The light-emitting elements 201 of the display panel 10 are arranged in an array. The display panel 10 includes at least two repeating light-emitting rows arranged along the second direction Y. The repeating light-emitting rows include a first light-emitting row, a second light-emitting row, a third light-emitting row, and a fourth light-emitting row arranged along the second direction. The first light-emitting row includes first light-emitting elements 2011 and third light-emitting elements 2013 alternately arranged along the first direction X. The second light-emitting row includes second light-emitting elements 2012 arranged along the first direction X. The third light-emitting row includes third light-emitting elements 2013 and first light-emitting elements 2011 alternately arranged along the first direction X. The fourth light-emitting row includes second light-emitting elements 2012 arranged along the first direction X. The light emitted by the light-emitting elements 201 in the same column of the first and third light-emitting rows is different in color. Furthermore, the second light-emitting elements 2012 in the second and fourth light-emitting rows are arranged in different colors. The light-emitting arrays are located between the light-emitting elements formed by the first and third light-emitting elements in the first and third light-emitting rows, respectively, with the first direction X and the second direction Y intersecting. On a reference plane parallel to the plane of the display panel 10, and in the orthographic projection of the reference plane: the first light-emitting element 2011 and the third light-emitting element 2013 adjacent to each other in the first direction X are defined as the central first light-emitting element 2111 and the central third light-emitting element 2113, respectively, and the color temperature sensor 11 is located between the central first light-emitting element 2111 and the central third light-emitting element 2113; in the second direction Y, an interference light sensor 12 is provided between the central first light-emitting element 2111 and the adjacent third light-emitting element 2013, and an interference light sensor 12 is provided between the central third light-emitting element 2113 and the adjacent first light-emitting element 2011. Among the color temperature sensor 11 and at least one interference light sensor 12 arranged around it: the distance between the color temperature sensor 11 and at least one adjacent light-emitting element 201 is the same as the distance between the interference light sensor 12 and the adjacent light-emitting element 201 with the same emitting color.

[0073] Understandable. Figure 15The schematic light-emitting elements 201 are arranged in an array. The display panel 10 includes at least two repeating light-emitting column units arranged along a first direction X. The repeating light-emitting column units include a first light-emitting element column to a fourth light-emitting element column arranged sequentially along the first direction X. The first light-emitting element column includes a first first light-emitting element 2011 and a first third light-emitting element 2013 arranged alternately along a second direction Y. The second light-emitting element column includes a plurality of second light-emitting elements 2012 arranged along the second direction Y. The third light-emitting element column includes a second third light-emitting element 2013 and a second first light-emitting element 2011 arranged alternately along the second direction Y. The fourth light-emitting column includes a plurality of second light-emitting elements 2012 arranged along the second direction Y. The first first light-emitting element 2011 of the first light-emitting element column and the second third light-emitting element 2013 of the third light-emitting element column are located in the same light-emitting element row, and the first third light-emitting element 2013 of the first light-emitting element column and the second first light-emitting element 2011 of the third light-emitting element column are located in the same light-emitting element row. In addition, a second light-emitting element 2012 of the second light-emitting element column and a second light-emitting element 2012 of the fourth light-emitting element column are located in the same light-emitting element row. Based on this arrangement of light-emitting elements 201, the spacing between the color temperature sensor 11 and at least one adjacent light-emitting element 201 is designed to be the same as the spacing between the interference light sensor 12 and an adjacent light-emitting element 201 of the same emitting color; for example Figure 15 The schematic sensor distribution satisfies at least one of the following conditions: Spacing a is the same as the distance between the color temperature sensor 11 and the central first light-emitting element 2111 and the distance between at least one interfering light sensor 12 and the adjacent first light-emitting element 2011; spacing b is the same as the distance between the color temperature sensor 11 and the adjacent second light-emitting element 2012 and the distance between at least one interfering light sensor 12 and the adjacent second light-emitting element 2012; spacing c is the same as the distance between the color temperature sensor 11 and the adjacent third light-emitting element 2013 and the distance between at least one interfering light sensor 12 and the adjacent third light-emitting element 2013. This not only ensures that the environments of the color temperature sensor 11 and the interfering light sensor 12 are basically consistent, resulting in high consistency of the interfering light collected by the color temperature sensor 11 and the interfering light sensor 12, but also allows for more accurate acquisition of the interfering light component through multiple interfering light sensors 12. Consequently, when removing the interfering light component from the ambient light data collected by the color temperature sensor 11, the obtained ambient light data is more accurate, improving the precision of color temperature detection.

[0074] refer to Figure 16The diagram shown is a schematic diagram of the distribution of another sensor and light-emitting element provided in the embodiment of this application. The light-emitting element 201 provided in the embodiment of this application includes a first light-emitting element 2011, a second light-emitting element 2012 and a third light-emitting element 2013 with different light-emitting colors; for example, the first light-emitting element 2011 is a blue light-emitting element, the second light-emitting element 2012 is a green light-emitting element and the third light-emitting element 2013 is a red light-emitting element. The light-emitting elements 201 of the display panel 10 are arranged in an array. The display panel 10 includes at least two repeating light-emitting rows arranged along the second direction Y. The repeating light-emitting rows include a first light-emitting row, a second light-emitting row, a third light-emitting row, and a fourth light-emitting row arranged along the second direction. The first light-emitting row includes a first light-emitting element 2011 and a third light-emitting element 2013 arranged alternately along the first direction X. The second light-emitting row includes a second light-emitting element 2012 arranged along the first direction X. The third light-emitting row includes a third light-emitting element 2013 and a first light-emitting element 2011 arranged alternately along the first direction X. The fourth light-emitting row includes a second light-emitting element 2012 arranged along the first direction X. The light emitted by the light-emitting elements 201 in the same column of the first and third light-emitting rows is different.
