[0052] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] Various modifications and variations can be made to this application without departing from its spirit or scope, which will be apparent to those skilled in the art. Therefore, this application is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the implementation methods provided in the embodiments of this application can be combined with each other without contradiction.

[0054] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] As described in the background section, improving the display quality of display panels has become a research direction for those skilled in the art.

[0056] It should be noted that, due to limitations in its manufacturing process and electro-drive principle, OLED display panels generally suffer from uneven brightness (known in the industry as "Mura"). Mura is one of the most common defect types in OLED display panels, severely affecting display quality.

[0057] Currently, the process of eliminating brightness unevenness in the display field is called De-mura. De-mura is a crucial and indispensable process in OLED display panel manufacturing. Specifically, the current De-mura method for OLED display panels involves measuring each frame during production to calculate the De-mura compensation coefficient for each frame, which is then burned into the timing controller of the display panel. When the OLED display panel displays an image, the display data provided by the OLED display panel's control system is used to calculate the De-mura compensation coefficient in the timing controller, resulting in new data that is sent to each pixel of the display panel, ultimately outputting an optimized image. Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the display panel before compensation. Figure 2 This is a schematic diagram of the display screen after compensation. From Figure 1 and Figure 2 As can be seen, the brightness uniformity of the display screen after compensation is greatly improved.

[0058] However, the applicant's research found that OLED display panels, due to their self-emissive properties, generate localized heat. Temperature changes in OLED display panels have a significant impact on the materials of OLED light-emitting devices. For example, the red, green, and blue colors change with temperature, causing color shifts in the OLED display panel's image and affecting the display quality.

[0059] like Figure 3 and Figure 4 As shown, Figure 4 It shows Figure 3 A schematic diagram of temperature distribution at different locations in the middle, where, Figure 3 The temperature of the display area corresponding to position ① is 35.2℃, the temperature of the display area corresponding to position ② is 37.2℃, the temperature of the display area corresponding to position ③ is 34.7℃, the temperature of the display area corresponding to position ④ is 35.8℃, the temperature of the display area corresponding to position ⑤ is 39.3℃, the temperature of the display area corresponding to position ⑥ is 38.6℃, the temperature of the display area corresponding to position ⑦ is 37.7℃, the temperature of the display area corresponding to position ⑧ is 42.8℃, and the temperature of the display area corresponding to position ⑨ is 42.2℃.

[0060] In view of this, embodiments of this application provide an electronic device, such as... Figure 5 As shown, the electronic device includes: a first body and a temperature detection module, wherein,

[0061] The first body includes a display panel 10, such as Figure 6As shown, the display panel 10 includes at least one first display area 11 and at least one second display area 12. The first display area 11 and the second display area 12 do not overlap, and the temperature influencing factors of the first display area 11 and the second display area 12 are different.

[0062] The temperature detection module includes at least two temperature detection elements 20 for detecting the temperature of the first display area 11 and the second display area 12. The temperatures of the first display area 11 and the second display area 12 are detected by different temperature detection elements 20. It should be noted that if the display panel 10 includes at least two first display areas 11, the temperatures of the different first display areas 11 are also detected by different temperature detection elements 20. Similarly, if the display panel 10 includes at least two second display areas 12, the temperatures of the different second display areas 12 are also detected by different temperature detection elements 20.

[0063] The first body also includes a driving circuit 30, which is used to output driving current to each display pixel in the display panel 10 and control the display state of each display pixel. The driving current of each display pixel in the first display area 11 is related to the temperature of the first display area 11, and the driving current of each display pixel in the second display area 12 is related to the temperature of the second display area 12.

[0064] The electronic device provided in this application embodiment uses different temperature detection elements in the temperature detection module to detect the temperature of the first display area and the second display area of ​​the display panel, which are affected by different temperature factors. Based on the temperature of the first display area, the driving current of the display pixels in the first display area can be adjusted, and based on the temperature of the second display area, the driving current of the display pixels in the second display area can be adjusted. Furthermore, by adjusting the driving current of the display pixels in each display area of ​​the display panel, the display image of the display panel can be adjusted, improving the color shift phenomenon of the display image and enhancing the display quality of the display image.

[0065] Optionally, in one embodiment of this application, the temperature detection module uses different temperature detection elements to detect the temperature of the first display area and the second display area. Based on the temperature of the first display area and the second display area, the driving circuit adjusts the De-mura coefficient (brightness compensation coefficient) of each display pixel in the first display area and the second display area, thereby adjusting the driving current of each display pixel in the display panel, improving the display quality of the display screen, and alleviating the color shift phenomenon caused by the different temperatures of different display areas in the display panel.

[0066] Optionally, in one embodiment of this application, the display panel is an OLED display panel, and the display pixels include OLED light-emitting devices, so that the display panel has excellent characteristics such as high brightness, high luminous efficiency, high contrast, wide viewing angle, low power consumption, strong shock resistance, thinness and lightness, and the ability to realize flexible display.

[0067] Optionally, in one embodiment of this application, such as Figure 7 As shown, the first body also includes at least one first heating element 31, with one first heating element 31 corresponding to one first display area. It should be noted that in this embodiment, the temperature of the first display area depends on the first heating element 31, and the temperature of the second display area depends on a heat-generating object outside the electronic device. The temperature detection module includes at least two first temperature detection elements 21, which are disposed on the first body and used to detect the temperature of different display areas.

[0068] It should be noted that if the first body includes at least two first heating elements, different first heating elements correspond to different first display areas, and the temperature of different first display areas is detected by different first temperature detection elements, it should also be noted that in this embodiment, the temperature of different first display areas may be the same or different, depending on the temperature of their corresponding first heating elements.

[0069] Based on the above embodiments, in one embodiment of this application, the temperature of the second display area depends on the ambient temperature of the electronic device. However, this application does not limit this. In other embodiments of this application, if there are other heat-generating objects around the electronic device, and the heat generated by the heat-generating objects can make the temperature of the second display area of ​​the electronic device higher than the ambient temperature, then the temperature of the second display area depends on the temperature of the heat-generating objects, depending on the specific circumstances.

[0070] Based on any of the above embodiments, in one embodiment of this application, the electronic device only includes a first body, such as a mobile phone. Figure 8 As shown, it can also be a tablet computer, such as... Figure 9 As shown, it can also be a desktop computer or an all-in-one computer, such as... Figure 10 As shown, etc.; in another embodiment of this application, the electronic device includes not only a first body but also a second body, the second body and the first body being rotatably connected, such as the electronic device being a laptop computer, etc. Figure 11 As shown, etc., this application does not limit this, but depends on the specific circumstances.

[0071] Optionally, in one embodiment of this application, the first temperature sensing element is at least partially disposed in the region with the highest temperature in the first body, thereby facilitating the detection of the temperature of the display area with the highest temperature in the display panel, so as to improve the display quality of the region with the most obvious color shift phenomenon in the display panel. However, this application does not limit this, and it depends on the specific circumstances.

[0072] Optionally, in one embodiment of this application, the electronic device comprises only a first body, and all heating elements in the electronic device are located on the first body, such as... Figure 7 and Figure 12 As shown, its main heat-generating components include a battery 313, a motherboard 312, and a drive circuit board 311, which generate a significant amount of heat. Therefore, in this embodiment, the first body includes at least three first heat-generating elements 21, corresponding to the battery 313, motherboard 312, and drive circuit board 311 of the electronic device, respectively. Correspondingly, the display panel includes at least three first display areas, wherein the temperature of one first display area depends on the temperature of the battery 313, the temperature of another first display area depends on the temperature of the motherboard 312, and the temperature of yet another first display area depends on the temperature of the drive circuit board 311. The temperatures of different first display areas are detected by different first temperature detection elements 21, and the first temperature detection elements used to detect the temperature of each first display area are all disposed on the first body. It should be noted that, in this embodiment, the drive circuit is disposed on the drive circuit board, the battery is used to provide operating voltage to the electronic device, and the motherboard is used to control the operating state of the electronic device.

[0073] In another embodiment of this application, such as Figure 13As shown, the electronic device includes not only a first body 100 but also a second body 200. A portion of the heating element in the electronic device is located in the first body 100, and a portion is located in the second body 200. In this embodiment, the second body 200 includes at least one second heating element 32. Optionally, in one embodiment of this application, the heat generated by the second heating element 32 has no effect on the display state of the display pixels in the display panel; in another embodiment of this application, when the electronic device is in a target posture, the heat generated by the second heating element 32 can affect the display state of the display pixels in the display panel.

[0074] It should be noted that if the heat generated by the second heating element does not affect the display state of the display pixels in the display panel, the temperature of the first display area also depends on its corresponding first heating element, and the temperature of the second display area also depends on the heat-generating object outside the electronic device; if the heat generated by the second heating element can affect the display state of the display pixels in the display panel when the electronic device is in the target posture, the temperatures of the first display area and the second display area also depend on the second heating element. Specifically, the temperature of the first display area depends on its corresponding first heating element and second heating element, and the temperature of the second display area depends on the heat-generating object outside the electronic device and the second heating element.

[0075] Based on the above embodiments, in one embodiment of this application, the following continues... Figure 13 As shown, the temperature detection module further includes at least one second temperature detection element 22, which is disposed in the second body 200 and is used to detect the second temperature of the corresponding display area; wherein, the temperature of the corresponding display area is determined according to the first temperature and the second temperature, and the corresponding display area is the first display area or the second display area affected by the second heating element 32.

[0076] Specifically, if the corresponding display area is a first display area, the temperature of the first display area is determined by a first temperature detected by a first temperature detection element and a second temperature detected by a second temperature detection element; if the corresponding display area is a second display area, the temperature of the second display area is determined by a first temperature detected by a first temperature detection element and a second temperature detected by a second temperature detection element.

[0077] It should be noted that the second body may include one second heating element or at least two second heating elements. If the second body includes at least two second heating elements, then the temperature detection module includes at least two second temperature detection elements, which are used to detect the second temperature of the corresponding display area corresponding to different second heating elements.

[0078] It should also be noted that if both the first display area and the second display area are affected by the heat generated by the second heating element, the second heating element affecting the temperature of the first display area and the second display area may be the same or different. The difference in the second heating element affecting the temperature of the first display area and the second display area may be that the second heating element affecting the temperature of the first display area and the second display area are completely different, or the second heating element affecting the temperature of the first display area and the second display area may be partially different. This application does not limit this, and it depends on the specific situation.

[0079] In addition, when the second body includes at least two second heating elements, the temperature of a corresponding display area may be affected by the heat generated by only one second heating element in the second body, or it may be affected by at least two second heating elements in the second body. This application does not limit this, and it depends on the specific situation.

[0080] Optionally, in one embodiment of this application, the following continues... Figure 13 As shown, the second temperature detection element 22 corresponds one-to-one with the second heating element 32, and the second temperature detection element 22 is disposed on its corresponding second heating element 32. However, this application does not limit this, as long as the second temperature detection element 22 can detect the second temperature of the corresponding display area.

[0081] Continuing with the example that the heat-generating components affecting the display state of the display pixels of the electronic device are mainly the battery, motherboard, and driver circuit board, optionally, in one embodiment of this application, continuing as follows... Figure 13 As shown, the driving circuit board 311 is disposed on the first body 100, and the battery 322 and the motherboard 321 are disposed on the second body 200. However, this application does not limit this. In other embodiments of this application, the heat-generating elements that affect the display state of the display pixels of the display panel in the electronic device may adopt other distribution methods, depending on the specific situation.

[0082] Based on any of the above embodiments, in one embodiment of this application, when the electronic device is in the target posture, the first body and the second body are stacked. At this time, the display area on the first body is close to the second heating element on the second body, making the temperature of the first display area and / or the second display area easily affected by the heat generated by the second heating element on the second body. However, this application does not limit this. In other embodiments of this application, when the electronic device is in the target posture, the first body and the second body may have other relative positions, such as the first body and the second body being at a certain angle, and the corresponding display area on the first body being close to the position of the second heating element on the second body, depending on the specific situation.

[0083] Optionally, in one embodiment of this application, such as Figure 14 As shown, when the electronic device includes a first body 100 and a second body 200 rotatably connected, the first body 100 has a first surface 101 and a second surface 102 facing each other, wherein the first surface 101 is surface A of the electronic device, and the second surface 102 is surface B of the electronic device. In this embodiment, the display area of ​​the first body 100 may be located only on the second surface 102 of the electronic device, or it may be partially located on the first surface 101 and partially located on the second surface 102 of the electronic device.

[0084] Based on the above embodiments, in one embodiment of this application, when the display area of ​​the first body is partially located on the first surface of the first body and partially located on the second surface of the first body, such as... Figure 15 As shown, when the electronic device is in the target posture, the second surface 102 of the first body 100 and the second body 200 are positioned facing each other. The display areas in the first body 100 that are in display state are all located on the first surface 101 of the first body 100. Correspondingly, the corresponding display areas are also located on the first surface 101 of the first body 100. However, this application does not limit this, and it depends on the specific circumstances.

[0085] Based on any of the above embodiments, in one embodiment of this application, such as Figure 16 and Figure 17 As shown, the display panel is a bendable display panel. In this embodiment, the display panel includes a first display portion 13 and a second display portion 14; different display portions include at least one second display area, or different display portions include at least one first display area and at least one second display area.

[0086] Based on the above embodiments, in one embodiment of this application, the display panel is in a first posture, in which the first display portion and the second display portion are located in the same plane, that is, the display area of ​​the display panel is in a flattened state. At this time, when the display panel is in the display state, both the first display portion and the second display portion are in the display state. Therefore, all the first temperature detection elements are in the working state to detect the temperature of each display area of ​​the display panel. The display panel is in a second posture, in which there is an angle between the first display portion and the second display portion. At this time, when the display panel is in the display state, both the first display portion and the second display portion are in the display state. Therefore, all the first temperature detection elements are also in the working state to detect the temperature of each display area of ​​the display panel.

[0087] Optionally, in one embodiment of this application, the display panel is in a third state. In this state, a portion of the display area is in a display state, and a portion is in a non-display state. At this time, the first temperature detection element located in the displayable portion of the first body is operational to detect the temperature of the displayable portion. It should be noted that in this embodiment, the non-displayable portion may or may not have a first heating element. Even if the non-displayable portion has a first heating element, the heat generated by that element may or may not affect the temperature of the displayable portion.

[0088] Therefore, in one embodiment of this application, the first temperature detection element provided in the non-displaying part is not detected, so that when the non-displaying part is not provided with the first heating element, or the non-displaying part is provided with the first heating element but the heat generated by the first heating element cannot affect the temperature of the displaying part, the temperature of the displaying part in the display panel can be detected, and the number of first temperature detection elements in the working state in the temperature detection module can be reduced, thereby reducing the power consumption of the electronic device.

[0089] In another embodiment of this application, the first temperature detection element provided in the non-display portion can also be in a working state, so as to improve the temperature detection accuracy of the display portion when the first heating element provided in the non-display portion can affect the display state of the display pixels of the display portion. However, this application does not limit this, and it depends on the specific situation.

[0090] Based on the above embodiments, in one embodiment of this application, the following continues... Figure 17As shown, in the third posture, the first display portion 13 and the second display portion 14 are stacked. Optionally, in one embodiment of this application, the display panel is a foldable display panel, and the display panel is in an outward folded state. At this time, the first display portion 13 and the second display portion 14 are stacked, and the display area of ​​the display panel is at least partially visible to the user. In another embodiment of this application, as... Figure 18 As shown, the display panel is a foldable display panel, for example, including a first display portion 13, a third display portion 15, and a second display portion 14 arranged perpendicular to the bending axis. The third display portion 15 is located between the first display portion 13 and the second display portion 14. In this case, the first display portion 13, the third display portion 15, and the second display portion 14 are stacked, with the display areas of the first display portion 13 and the third display portion 15 facing each other, and the display areas of the third display portion 15 and the second display portion 14 facing away from each other, so that the first display portion 13 and the second display portion 14 are stacked and the display area of ​​the second display portion 14 is visible to the user. In other embodiments of this application, the display panel may have more bendable portions, which is not limited in this application and depends on the specific circumstances.

[0091] It should be noted that in the above embodiments, the electronic device may only include the first body, such as a bendable mobile phone or tablet computer, or it may include both the first body and the second body, such as a laptop computer whose display screen is a bendable display panel. Figure 19 As shown, this application does not limit this, and specific matters can be determined.

[0092] Specifically, in one embodiment of this application, when the electronic device includes a first body and a second body, and the second body includes at least one second heating element, the heat generated by the second heating element may or may not affect the display state of the display pixels of the display portion of the display panel that is in operation.

[0093] Therefore, in one embodiment of this application, when the display panel is in a third posture, if the part that can be displayed belongs to the corresponding display area, the second temperature detection element is in working state to improve the temperature detection accuracy of the part that can be displayed.

[0094] Specifically, in one optional embodiment of this application, when the display panel is in the third state, the heat generated by each of the second heating elements in the electronic device will affect the temperature of the display portion of the display panel in the display state. In this embodiment, all the second temperature detection elements in the second body are in working state to improve the temperature detection accuracy of the display portion of the display panel in the display state. In another embodiment of this application, when the display panel is in the third state, the heat generated by some of the second heating elements in the second electronic device will affect the temperature of the display portion of the display panel in the display state, while the heat generated by some of the second heating elements will not affect the temperature of the display portion of the display panel in the display state. However, in this embodiment, the second temperature detection elements corresponding to the second heating elements that can affect the temperature of the display portion of the display panel in the display state are in working state, while the second temperature detection elements corresponding to the second heating elements that cannot affect the temperature of the display portion of the display panel in the display state are in non-working state. This reduces the number of second temperature detection elements in working state in the temperature detection module and reduces the power consumption of the electronic device, based on the detection of the temperature of the display portion of the display panel in the display state.

[0095] The electronic device provided in the embodiments of this application will now be described in conjunction with specific examples.

[0096] Optionally, in one embodiment of this application, the electronic device is a bendable mobile phone or tablet computer. When the first display portion and the second display portion of the display panel are in a flattened state, or when there is a certain angle between the first display portion and the second display portion of the display panel, each of the first temperature detection elements in the first body is in a working state to realize temperature detection of each display area of ​​the display panel. When the electronic device is in an outward folded state, if the first display portion and the second display portion are stacked and the display areas of the first display portion and the second display portion are arranged opposite to each other, one of the first display portion and the second display portion in the display panel is in a display state and the other display portion is in a non-display state. At this time, the first temperature detection element set in the displayable portion of the first body is in a working state. If the non-displayable portion of the first body is provided with a first heating element, and the heat generated by the first heating element affects the display portion, then the first temperature detection element set in the non-displayable portion is also in a working state. Conversely, if the non-displayable portion of the first body is not provided with a first heating element, or the non-displayable portion is provided with a first heating element but the heat generated by the first heating element does not affect the display portion, then the first temperature detection element set in the non-displayable portion is in a non-working state.

[0097] In another embodiment of this application, the electronic device is a laptop computer, comprising a first body containing a display panel and a second body containing input components. In this embodiment, the first body containing the display panel is a bendable portion, for example, the display panel is a folded display panel. In this case, the first display portion and the second display portion of the display panel are in a flattened state, or when there is a certain angle between the first display portion and the second display portion of the display panel, each of the first temperature detection elements in the first body is in a working state to realize temperature detection of each display area of ​​the display panel. When the display panel is in an outward folded state, and the first display portion and the second display portion are stacked, the display areas of the first display portion and the second display portion are opposite to each other. In this configuration, one of the first and second display portions in the display panel is in a display state, while the other is in a non-display state. At this time, the first temperature detection element installed in the displayable portion of the first body is in a working state. If the non-displayable portion of the first body is equipped with a first heating element, and the heat generated by the first heating element affects the display portion, then the first temperature detection element installed in the non-displayable portion is also in a working state. Conversely, if the non-displayable portion of the first body is not equipped with a first heating element, or if the non-displayable portion is equipped with a first heating element but the heat generated by the first heating element does not affect the display portion, then the first temperature detection element installed in the non-displayable portion is in a non-working state.

[0098] In another embodiment of this application, the electronic device is a laptop computer, comprising a first body containing a display panel and a second body containing an input component. In this embodiment, the first body containing the display panel is a bendable portion, for example, the display panel is a bi-fold display panel, including a first display portion, a third display portion, and a second display portion arranged perpendicular to the bending axis. The third display portion is located between the first display portion and the second display portion. In this case, if the first display portion, the third display portion, and the second display portion are stacked, the display areas of the first display portion and the third display portion face each other, and the display areas of the third display portion and the second display portion face away from each other, so that the first display portion and the second display portion are stacked and the display area of ​​the second display portion is visible to the user.

[0099] In the above embodiments, the first temperature detection element provided in the displayable portion of the first body is in working condition. If the non-displayable portion of the first body is provided with a first heating element, and the heat generated by the first heating element affects the displayable portion, then the first temperature detection element provided in the non-displayable portion is also in working condition. Conversely, if the non-displayable portion of the first body is not provided with a first heating element, or if the non-displayable portion is provided with a first heating element but the heat generated by the first heating element does not affect the displayable portion, then the first temperature detection element provided in the non-displayable portion is in non-working condition.

[0100] It should be noted that, in the above embodiments, the heat generated by the second heating element in the second body may also affect the display state of the display pixels in the display panel. Therefore, the second temperature detection element corresponding to the second heating element in the second body that can affect the display state of the display pixels in the display panel is also in working condition to improve the temperature detection accuracy of the displayable part.

[0101] Based on any of the above embodiments, in one embodiment of this application, such as Figure 7 , Figure 12 and Figure 13 As shown, a first temperature detection element 211 for detecting the temperature of the first display area is disposed on the first heating element 21 to improve the temperature detection accuracy of the first heating element 21, thereby improving the detection accuracy of the first temperature of the first display area affected by the first heating element 21. However, this application does not limit this, and it depends on the specific circumstances.

[0102] Based on any of the above embodiments, in one embodiment of this application, the following continues... Figure 7 , Figure 12 and Figure 13 As shown, a first temperature sensing element 212 for detecting the temperature of the second display area is set at a preset position on the first body. In a first direction perpendicular to the first body, the preset position is located within the projection range of the second display area, so as to improve the accuracy of the first temperature sensing element 21 for detecting the temperature of the second display area.

[0103] Optionally, in one embodiment of this application, the following continues... Figure 12 and Figure 13As shown, the preset position corresponds to the boundary area of ​​the display area of ​​the display panel or the corner area of ​​the display area of ​​the display panel, so as to reduce the impact of the setting of the first temperature detection element 212 for detecting the temperature of the second display area on the original structure layout of the first body 100, based on the fact that the first temperature detection element 212 for detecting the temperature of the second display area can detect the temperature of the second display area. However, this application does not limit this, and it depends on the specific situation.

[0104] Based on the above embodiments, in one embodiment of this application, in order to further improve the temperature detection accuracy of the second display area, a first temperature detection element for detecting the temperature of the second display area is provided at each of the four corners of the first body. However, this application does not limit this and it depends on the specific circumstances.

[0105] Optionally, in one embodiment of this application, the first body further includes a housing with a receiving space, the display panel being located within the receiving space, and a first temperature sensing element for detecting the temperature of the second display area being disposed on the housing of the first body. This facilitates the placement of the first temperature sensing element for detecting the temperature of the second display area and further reduces the impact of the placement of the first temperature sensing element for detecting the temperature of the second display area on the layout of the original structure in the display panel. Specifically, the first temperature sensing element for detecting the temperature of the second display area may be disposed on the back of the housing, i.e., on the side opposite to the display side of the display panel. However, this application does not limit this and it depends on the specific circumstances.

[0106] Based on any of the above embodiments, in one embodiment of this application, the driving circuit is further configured to determine a compensation coefficient for the driving current of each display pixel in the display state in the first display area and the second display area based on the temperature detected by the first temperature detection element and / or the second temperature detection element, so as to adjust the driving current of each display pixel in the display state in the first display area and the second display area based on the compensation coefficient, thereby improving the color shift phenomenon of the display screen and improving the display quality.

[0107] Specifically, in one embodiment of this application, the driving circuit determines the compensation coefficient of the driving current of each display pixel in the first display area under display state based on the temperature detected by the temperature detection element for detecting the first display area, and determines the compensation coefficient of the driving current of each display pixel in the second display area under display state based on the temperature detected by the temperature detection element for detecting the second display area.

[0108] Optionally, based on the above embodiments, in one embodiment of this application, if the display panel further includes a third display area located between the first display area and the second display area, the driving circuit can also determine the compensation coefficient of the driving current of each display pixel in the display state in the third display area based on the temperature detected by the temperature detection element for detecting the first display area and the temperature detected by the temperature detection element for detecting the second display area, thereby adjusting the driving current of each display pixel in the third display area located between the first display area and the second display area, and further improving the overall quality of the display screen of the display panel. However, this application does not limit this, and it depends on the specific circumstances.

[0109] Optionally, in one embodiment of this application, the following continues... Figure 13 As shown, the driving circuit includes a temperature processor 3111 and a timing controller 3112. The temperature processor 3111 receives the temperature detected by each temperature detection element in the temperature detection module and sends the temperature detected by each temperature detection element and the position of each temperature detection element to the timing controller 3113. The timing controller 3113 determines the display area corresponding to each temperature detection element through an algorithm, and optimizes the driving current compensation coefficient of the display pixels of each display area based on the temperature detected by the temperature detection element corresponding to each display area. Then, based on the optimized driving current compensation coefficient of each display pixel, it provides driving current to the display pixels of each display area to improve the uniformity of display brightness and reduce color shift phenomenon of the display screen.

[0110] Specifically, in one embodiment of this application, each temperature sensing element is connected to the temperature processor via an external connector to transmit the temperature signal it detects to the temperature processor. However, this application does not limit this and it depends on the specific circumstances.

[0111] As can be seen from the above, in the electronic device provided in this application embodiment, based on the temperature influence factors of each display area in the display panel, the display panel is divided into at least one first display area and at least one second display area. A temperature detection module is then used to detect the temperatures of the first and second display areas. Based on the temperatures of the first and second display areas, the compensation coefficient of the driving current of each display pixel in the display panel that is in display state is optimized to adjust the driving current of each display pixel. It should be noted that the electronic device provided in this application embodiment, by performing partitioned image compensation optimization on the entire display panel, can improve the quality of the displayed image by optimizing the overall compensation coefficient of the display pixels in each display area, resulting in higher image compensation accuracy.

[0112] In summary, the electronic device provided in this application embodiment effectively improves color shift and enhances display quality by increasing the brightness uniformity of the display panel. Furthermore, during operation, the temperature of each display area of ​​the display panel may change. This application embodiment optimizes the driving current compensation coefficient of the display pixels in each display area based on real-time temperature detection, enabling real-time adjustment of the display image and further improving display quality.

[0113] Accordingly, embodiments of this application also provide a control method, such as... Figure 20 As shown, the method includes:

[0114] S1: Determine the display area in the display state in the electronic device, the electronic device includes a first body and a temperature detection module, wherein the first body includes a display panel, the display panel includes at least one first display area and at least one second display area, the first display area and the second display area do not overlap, and the temperature influencing factors of the first display area and the second display area are different;

[0115] S2: Based on the temperature influencing factors of the display area in the display state in the electronic device, determine the temperature detection element in the temperature detection module used to collect the temperature of the display area in the display state;

[0116] S3: Enable the temperature detection element used to collect the temperature of the display area in the display state, and collect the temperature of the display area in the display state;

[0117] S4: Based on the temperature of the display area in the display state, determine the driving current of each display pixel in the display area in the display state, so that the driving circuit in the first body controls the display state of each display pixel in the display area in the display state based on the driving current.

[0118] The control method provided in this application first determines the temperature detection element in the temperature detection module used to collect the temperature of the display area in the display state based on the temperature influencing factors of the display area in the display state in the display device and the display area in the display state in the electronic device. Then, the temperature detection element used to collect the temperature of the display area in the display state is enabled to collect the temperature of the display area in the display state. This allows for the detection of the temperatures of the first display area and the second display area in the display panel affected by different temperature influencing factors. Based on the temperature of the first display area, the driving current of the display pixels in the first display area can be adjusted, and based on the temperature of the second display area, the driving current of the display pixels in the second display area can be adjusted. By adjusting the driving current of the display pixels in each display area of ​​the display panel, the display image of the display panel can be adjusted, improving the color shift phenomenon of the display image and enhancing the display quality of the display image.

[0119] Optionally, in one embodiment of this application, the control method uses different temperature detection elements to detect the temperature of the first display area and the second display area, so as to adjust the De-mura coefficient (brightness compensation coefficient) of each display pixel in the first display area and the second display area based on the temperature of the first display area and the second display area, thereby adjusting the driving current of each display pixel in the display panel, improving the display quality of the display screen, and alleviating the color shift phenomenon caused by the different temperatures of different display areas in the display panel.

[0120] Optionally, in one embodiment of this application, the first body further includes at least one first heating element, with one first heating element corresponding to one first display area. It should be noted that in this embodiment, the temperature of the first display area depends on the first heating element, and the temperature of the second display area depends on a heat-generating object outside the electronic device. The temperature detection module includes at least two first temperature detection elements, which are disposed on the first body and used to detect the temperature of different display areas.

[0121] Optionally, in one embodiment of this application, the first temperature sensing element is at least partially disposed in the region with the highest temperature in the first body, thereby facilitating the detection of the temperature of the display area with the highest temperature in the display panel, so as to improve the display quality of the region with the most obvious color shift phenomenon in the display panel. However, this application does not limit this, and it depends on the specific circumstances.

[0122] Optionally, in one embodiment of this application, the electronic device includes only a first body, and all the heat-generating elements in the electronic device are located on the first body. Its main heat-generating elements include a battery, a motherboard, and a driver circuit board, which generate a significant amount of heat. Therefore, in this embodiment, the first body includes at least three first heat-generating elements, corresponding to the battery, motherboard, and driver circuit board of the electronic device, respectively. Correspondingly, the display panel includes at least three first display areas, wherein the temperature of one first display area depends on the temperature of the battery, the temperature of another first display area depends on the temperature of the motherboard, and the temperature of yet another first display area depends on the temperature of the driver circuit board. The temperatures of different first display areas are detected by different first temperature detection elements, and all first temperature detection elements used to detect the temperature of each first display area are disposed on the first body. It should be noted that in this embodiment, the driver circuit is disposed on the driver circuit board, the battery provides the operating voltage to the electronic device, and the motherboard controls the operating state of the electronic device.

[0123] In another embodiment of this application, the electronic device includes not only a first body but also a second body. A heating element is partially located in the first body and partially in the second body. In this embodiment, the second body includes at least one second heating element. Optionally, in one embodiment of this application, the heat generated by the second heating element has no effect on the display state of the display pixels in the display panel; in another embodiment of this application, when the electronic device is in a target posture, the heat generated by the second heating element can affect the display state of the display pixels in the display panel.

[0124] It should be noted that if the heat generated by the second heating element does not affect the display state of the display pixels in the display panel, the temperature of the first display area also depends on its corresponding first heating element, and the temperature of the second display area also depends on the heat-generating object outside the electronic device; if the heat generated by the second heating element can affect the display state of the display pixels in the display panel when the electronic device is in the target posture, the temperatures of the first display area and the second display area also depend on the second heating element. Specifically, the temperature of the first display area depends on its corresponding first heating element and second heating element, and the temperature of the second display area depends on the heat-generating object outside the electronic device and the second heating element.

[0125] Based on the above embodiments, in one embodiment of this application, the temperature detection module further includes at least one second temperature detection element, which is disposed in the second body and used to detect a second temperature of a corresponding display area; wherein, the temperature of the corresponding display area is determined based on the first temperature and the second temperature, and the corresponding display area is either the first display area or the second display area affected by the second heating element. In this embodiment, the control method, when enabling the temperature detection element for collecting the temperature of the display area in the display state, includes: enabling the first temperature detection element for collecting the temperature of the display area in the display state, collecting the first temperature of the display area in the display state, and enabling the second temperature detection element for collecting the temperature of the display area in the display state, collecting the second temperature of the display area in the display state; the temperature of the display area in the display state is determined by the first temperature and the second temperature.

[0126] Specifically, if the corresponding display area is a first display area, the temperature of the first display area is determined by a first temperature detected by a first temperature detection element and a second temperature detected by a second temperature detection element; if the corresponding display area is a second display area, the temperature of the second display area is determined by a first temperature detected by a first temperature detection element and a second temperature detected by a second temperature detection element.

[0127] Continuing with the example that the main heat-generating components affecting the display state of the display pixels of the display panel in the electronic device are the battery, motherboard, and driver circuit board, optionally, in one embodiment of this application, when the electronic device includes a first body and a second body, the driver circuit board is disposed on the first body, and the battery and the motherboard are disposed on the second body. However, this application does not limit this. In other embodiments of this application, the heat-generating components affecting the display state of the display pixels of the display panel in the electronic device can also adopt other distribution methods, depending on the specific circumstances.

[0128] Based on any of the above embodiments, in one embodiment of this application, when the electronic device is in the target posture, the first body and the second body are stacked. At this time, the display area on the first body is close to the second heating element on the second body, making the temperature of the first display area and / or the second display area easily affected by the heat generated by the second heating element on the second body. However, this application does not limit this. In other embodiments of this application, when the electronic device is in the target posture, the first body and the second body may have other relative positions, such as the first body and the second body being at a certain angle, and the corresponding display area on the first body being close to the position of the second heating element on the second body, depending on the specific situation.

[0129] Optionally, in one embodiment of this application, when the electronic device includes a first body and a second body rotatably connected, the first body has a first surface and a second surface opposite to each other, wherein the first surface is surface A of the electronic device and the second surface is surface B of the electronic device. In this embodiment, the display area of ​​the first body may be located only on the second surface of the electronic device, or it may be partially located on the first surface and partially located on the second surface of the electronic device.

[0130] Based on the above embodiments, in one embodiment of this application, when the display area of ​​the first body is partially located on the first surface of the first body and partially located on the second surface of the first body, and the electronic device is in the target posture, the second surface of the first body and the second body face each other, and all display areas in the first body in the display state are located on the first surface of the first body. Correspondingly, the corresponding display areas are also located on the first surface of the first body. However, this application does not limit this, and it depends on the specific circumstances.

[0131] Based on any of the above embodiments, in one embodiment of this application, the display panel is a bendable display panel, and the control method further includes:

[0132] Detect the orientation of the display panel;

[0133] Based on the orientation of the display panel, the display portions in the display panel that are in a display state are determined. The display panel includes a first display portion and a second display portion. Different display portions include at least one second display area, or different display portions include at least one first display area and at least one second display area.

[0134] Optionally, in one embodiment of this application, the display panel is in a first posture, in which the first display portion and the second display portion are located in the same plane, that is, the display area of ​​the display panel is in a flattened state. At this time, when the display panel is in the display state, both the first display portion and the second display portion are in the display state. Therefore, all the first temperature detection elements are in the working state to detect the temperature of each display area of ​​the display panel. The display panel is in a second posture, in which there is an angle between the first display portion and the second display portion. At this time, when the display panel is in the display state, both the first display portion and the second display portion are in the display state. Therefore, all the first temperature detection elements are also in the working state to detect the temperature of each display area of ​​the display panel.

[0135] Optionally, in one embodiment of this application, the display panel is in a third state. In this state, a portion of the display area is in a display state, and a portion is in a non-display state. At this time, the first temperature detection element located in the displayable portion of the first body is operational to detect the temperature of the displayable portion. It should be noted that in this embodiment, the non-displayable portion may or may not have a first heating element. Even if the non-displayable portion has a first heating element, the heat generated by that element may or may not affect the temperature of the displayable portion.

[0136] Therefore, in one embodiment of this application, the first temperature detection element provided in the non-displaying part is not detected, so that when the non-displaying part is not provided with the first heating element, or the non-displaying part is provided with the first heating element but the heat generated by the first heating element cannot affect the temperature of the displaying part, the temperature of the displaying part in the display panel can be detected, and the number of first temperature detection elements in the working state in the temperature detection module can be reduced, thereby reducing the power consumption of the electronic device.

[0137] In another embodiment of this application, the first temperature detection element provided in the non-display portion can also be in a working state, so as to improve the temperature detection accuracy of the display portion when the first heating element provided in the non-display portion can affect the display state of the display pixels of the display portion. However, this application does not limit this, and it depends on the specific situation.

[0138] It should be noted that in the above embodiments, the electronic device may only include the first body, such as a bendable mobile phone or tablet computer, or it may include both the first body and the second body, such as a laptop computer whose display screen is a bendable display panel. This application does not limit this, and the specific details can be determined accordingly.

[0139] Specifically, in one embodiment of this application, when the electronic device includes a first body and a second body, and the second body includes at least one second heating element, the heat generated by the second heating element may or may not affect the display state of the display pixels of the display portion of the display panel that is in operation.

[0140] Therefore, in one embodiment of this application, when the display panel is in a third posture, if the part that can be displayed belongs to the corresponding display area, the second temperature detection element is in working state to improve the temperature detection accuracy of the part that can be displayed.

[0141] Specifically, in one optional embodiment of this application, when the display panel is in the third state, the heat generated by each of the second heating elements in the electronic device will affect the temperature of the display portion of the display panel in the display state. In this embodiment, all the second temperature detection elements in the second body are in working state to improve the temperature detection accuracy of the display portion of the display panel in the display state. In another embodiment of this application, when the display panel is in the third state, the heat generated by some of the second heating elements in the second electronic device will affect the temperature of the display portion of the display panel in the display state, while the heat generated by some of the second heating elements will not affect the temperature of the display portion of the display panel in the display state. However, in this embodiment, the second temperature detection elements corresponding to the second heating elements that can affect the temperature of the display portion of the display panel in the display state are in working state, while the second temperature detection elements corresponding to the second heating elements that cannot affect the temperature of the display portion of the display panel in the display state are in non-working state. This reduces the number of second temperature detection elements in working state in the temperature detection module and reduces the power consumption of the electronic device, based on the detection of the temperature of the display portion of the display panel in the display state.

[0142] Based on any of the above embodiments, in one embodiment of this application, determining the driving current of each display pixel in the display area in the display state based on the temperature of the display area in the display state, so that the driving circuit in the first body controls the display state of each display pixel in the display area in the display state based on the driving current, includes: optimizing the driving current compensation coefficient of the display pixel in each display area based on the temperature of the display area in the display state; determining the driving current of each display pixel in the display area in the display state based on the optimized driving current compensation coefficient of each display area, so as to provide driving current to the display pixel in the display area in the display state, thereby improving the uniformity of display brightness and reducing color shift in the display image.

[0143] In summary, the control method provided in this application first determines the temperature detection element in the temperature detection module used to collect data on the display area in the display state, based on the temperature influencing factors of the display area in the display device and the display area in the display state in the electronic device. Then, it enables the temperature detection element to collect the temperature of the display area in the display state, thereby detecting the temperature of the first and second display areas in the display panel affected by different temperature influencing factors. Based on the temperature of the first display area, the driving current of the display pixels in the first display area can be adjusted, and based on the temperature of the second display area, the driving current of the display pixels in the second display area can be adjusted. By adjusting the driving current of the display pixels in each display area of ​​the display panel, the display image of the display panel can be adjusted, improving the color shift phenomenon of the display image and enhancing the display quality of the display image.
