The electronic device 10 may include a folding screen 100, a first housing 200, and electronic components.

The folding screen 100 is used for displaying images, videos, and the like. The folding screen 100 includes a first portion 110, a second portion 120, and a third portion 130, the third portion 130 being disposed between the first portion 110 and the second portion 120, the third portion 130 being folded when the folding screen 100 is folded, and the first portion 110 being opposite the second portion 120. At least a third portion 130 of the folding screen 100 is made of a flexible material. The first portion 110 and the second portion 120 may be made of a flexible material, may be made of a rigid material, may be made of a flexible material, and may be made of a rigid material.

The folding screen 100 is supported on the first housing 200. The first housing 200 may include a first frame 211, a first rear cover 212, a second frame 221, a second rear cover 222, and a rotation mechanism 230, wherein the rotation mechanism 230 is connected between the first frame 211 and the second frame 221. The first portion 110 of the folding screen 100 is attached to the side of the first frame 211 away from the first rear cover 212, the second portion 120 of the folding screen 100 is attached to the side of the second frame 221 away from the second rear cover 222, and the third portion 130 of the folding screen 100 is attached to the rotating mechanism 230. The first housing 211 and the second housing 221 are rotatably coupled by a rotation mechanism 230, thereby enabling the electronic device 10 to rotate between an extended position and a collapsed position.

When the electronic device 10 is in the unfolded position as shown in fig. 2, the folding screen 100 is in the unfolded state, that is, the display surfaces of the first portion 110, the second portion 120, and the third portion 130 of the folding screen 100 are located in the same plane, that is, a large screen display mode is formed, so as to bring a better use experience to the user.

When the electronic device 10 is in the folded position as shown in fig. 3, the folding screen 100 is in a folded state, that is, the third portion 130 of the folding screen 100 is folded, and the first portion 110 is disposed opposite to the second portion 120. The first case 200 is protected outside the folding screen 100, and the folding screen 100 is not visible to the user, so that the folding screen 100 can be prevented from being scratched or damaged, and the folding screen 100 can be effectively protected.

Further, the first case 200 and the folding screen 100 together define an internal accommodating space for accommodating the electronic component. Wherein a portion of the interior space may be collectively enclosed by the first frame 211, the first rear cover 212, and the first portion 110 of the folding screen 100, and another portion of the interior space may be collectively enclosed by the second frame 221, the second rear cover 222, and the second portion 120 of the folding screen 100.

In some embodiments, referring to fig. 4, fig. 4 is a cross-sectional view of the electronic device 10 provided in fig. 1 in a folded position. The electronic device 10 may further include an external screen 223, where the external screen 223 is a non-folding display screen. The outer panel 223 may be disposed on the first frame 211 or the second frame 221, and disposed on a side of the first frame 211 or the second frame 221 away from the folding screen 100, i.e., the first rear cover 212 or the second rear cover 222 may be replaced by the outer panel 223. Illustratively, the outer screen 223 is disposed at a side of the second frame 221 remote from the second portion 120 of the folding screen 100, that is, the outer screen 223 is used in place of the second rear cover 222, so that another portion of the inner receiving space is defined by the outer screen 223, the second frame 221, and the second portion 120 of the folding screen 100. When the electronic device 10 is in the folded position, the user can view the mobile phone information through the external screen 223, which is beneficial to further improving the use experience of the user.

With continued reference to fig. 4, and with reference to fig. 5 in combination, fig. 5 is a block diagram of the electronic device 10 provided in fig. 1 in an unfolded state in the internal accommodating space (back view of the electronic device 10). The electronic components may include a main circuit board 300, a sub circuit board 310, an SoC chip 400, a battery 320, and the like. The main circuit board 300 is disposed in the first frame 211, the sub circuit board 310 is disposed in the second frame 221, the SoC chip 400 is disposed on the main circuit board 300, and the main circuit board 300 and the sub circuit board 310 can be electrically connected through an FPC board; the battery 320 may be provided with two batteries, and disposed in the first and second housings 211 and 221, respectively, and power electronic components disposed in the first and second housings 211 and 221, respectively.

The above-mentioned installation positions of the electronic components are only one possible example, and may be adjusted according to actual situations (e.g., design requirements), and are not considered as limiting the actual installation positions of the electronic components.

Since some electronic components generate heat during operation, the heat generated by the electronic components in the electronic device 10 during operation may cause the temperature of the electronic components in the vertical projection area on the folding screen 100 to increase. When the electronic device 10 is in the extended position, the folding screen 100 is in the extended state. Since the area of the folding screen 100 is large, and the heat generated by the electronic components located in the first frame 211 and the electronic components located in the second frame 221 are different, the temperature difference is easily generated due to the difference between the temperatures of the first portion 110 and the second portion 120 of the folding screen 100.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating a temperature distribution of a folding screen 100 of the electronic device 10 provided in fig. 1. Among the electronic components inside the electronic device 10, the electronic component having a large heat generation amount is the SoC chip 400, and therefore, when the electronic device 10 is in the extended position, the temperature of the vertical projection area of the SoC chip 400 on the folding screen 100 is high. For example, when the folding screen 100 displays a video, the temperature of the area a of the folding screen 100 corresponding to the SoC chip 400 is 45 ℃, and the area a is gradually extended in a direction away from the area a, and the temperature of the folding screen 100 gradually decreases. Wherein the temperature of the region of the second portion 120 of the folding screen 100 that is further from the region a is 35 c, i.e. in this use scenario the temperature difference between the region of the folding screen 100 that is the highest temperature and the region that is the lowest temperature reaches 10 c.

In this way, the difference between the aging speed of the display pixels in the higher temperature region and the aging speed of the display pixels in the lower temperature region of the folding screen 100 is larger due to the larger temperature difference between the different positions of the folding screen 100. Therefore, differences in display color and brightness of the display area of the folding screen 100 may occur, which affect the display effect of the folding screen 100, thereby affecting the user experience.

In order to solve the above-mentioned problems, referring to fig. 7, fig. 7 is a cross-sectional view of another electronic device 10 in a folded position according to the present application, the electronic device 10 includes the folding screen 100, the first housing 200, and electronic components (hereinafter, the electronic components are referred to as SoC chip 400).

In addition, the electronic device 10 further includes a heating element 500 disposed in the first housing 200, and a vertical projection of the heating element 500 on the folding screen 100 and a vertical projection of the SoC chip 400 on the folding screen 100 are offset from each other. Since the electronic device 10 is a folding-screen mobile phone, the above-mentioned vertical projection misalignment means that the electronic device 10 is in the unfolded position, that is, the vertical projection of the heating element 500 and the SoC chip 400 on the folding screen 100 are misaligned when the folding screen 100 is in the unfolded state.

Specifically, the heating element 500 may include a first heating element 510, and the first heating element 510 is disposed in the second frame 221 and electrically connected to the main circuit board 300 or the sub circuit board 310. For example, the first heating element 510 may be electrically connected with the sub-circuit board 310 and electrically connected with the main circuit board 300 through the sub-circuit board 310, thereby realizing that the heating element 500 is controlled by the SoC chip 400. Or the heating element 500 may be directly electrically connected to the main circuit board 300 through a flexible connection (e.g., FPC board). The present application is not particularly limited thereto.

In this way, the first heating element 510 is arranged in the second casing 221, i.e. the vertical projection of the first heating element 510 on the folding screen 100 is located on the second portion 120; further, since the SoC chip 400 is disposed in the first housing 211 and the vertical projection thereof onto the folding screen 100 is located on the first portion 110, the vertical projections of the first heating element 510 and the SoC chip 400 onto the folding screen 100 are offset from each other when the folding screen 100 is in the unfolded state. Therefore, in the working process of the electronic device 10, when the heat productivity of the SoC chip 400 is larger, and the temperature difference between the first portion 110 and the second portion 120 of the folded screen 100 is larger, the second portion 120 of the folded screen 100 can be heated by the first heating element 510, so that the temperature of the second portion 120 of the folded screen 100 is increased, and the temperature difference between the first portion 110 and the second portion 120 can be reduced, so that the situation that the aging speed difference of the display pixels is large due to different temperatures in different areas of the folded screen 100 is avoided, and further, the display color and brightness of the folded screen 100 are not greatly different is ensured, and the display effect of the folded screen 100 is improved.

Or when the local temperature of the folding screen 100 is greater than the set temperature, the first heating element 510 is activated to heat a corresponding area on the folding screen 100. For example, when the temperature of a certain area on the folding screen 100 is greater than or equal to 40 ℃, the first heating element is controlled to start heating, so that the situation that the aging speed of the display pixels is large due to different temperatures of different areas of the folding screen 100 is avoided. It will be appreciated that the set temperature may also be set to different temperatures, for example, 42 ℃, 45 ℃, 48 ℃, 50 ℃, 60 ℃, etc., depending on the actual use requirements.

Specifically, referring to fig. 8, fig. 8 is a partial sectional view of the electronic device 10 provided in fig. 7. The first heating element 510 may include a substrate 511 and a heat generating layer 512, the substrate 511 is fixed in the second frame 221, the heat generating layer 512 is disposed on a surface of the substrate 511 facing the folding screen 100, and the heat generating layer 512 is electrically connected to the main circuit board 300 or the sub circuit board 310 shown in fig. 5. That is, the substrate 511 is fixed in the second frame 221, so as to support the heat-generating layer 512, and the heat-generating layer 512 is electrically connected with the control circuit, when the temperature difference between the first portion 110 and the second portion 120 of the folding screen 100 is large, the control circuit can energize the heat-generating layer 512, so that the heat-generating layer 512 generates heat to heat the second portion 120 of the folding screen 100, thereby reducing the temperature difference between the first portion 110 and the second portion 120 of the folding screen 100, and ensuring that the display color and the brightness of the folding screen 100 are greatly different.

Referring to fig. 9, fig. 9 is a schematic diagram of a first heating element 510 according to an embodiment of the present application, where the heat generating layer 512 may include conductive wires. For example, the resistance wire with smaller width is bent and arranged on the substrate 511, so that the uniformly distributed metal wires have larger impedance, and when the control circuit supplies power to the conductive metal layer, the conductive metal layer can generate larger heat to heat the second portion 120 of the folding screen 100.

Or referring to fig. 10, fig. 10 is a schematic diagram of another first heating element 510 according to an embodiment of the present application, where the heat generating layer 512 may further include a graphene layer. For example, when the graphene layer is energized, the graphene itself has good electric and thermal conductivity, and thus the energized graphene can generate heat, thereby heating the second portion 120 of the folding screen 100.

In one possible embodiment, the first heating element 510 may be directly attached to the second portion 120 of the folding screen 100, that is, the heat-generating layer 512 is disposed between the substrate 511 and the second portion 120 of the folding screen 100 (as shown in fig. 7 and 8), and the heat-generating layer 512 may be directly contacted with the second portion 120 of the folding screen 100 so as to heat the second portion 120 of the folding screen 100.

The substrate 511 may be fixedly connected to the second housing 221; or may be fixed to other structural members inside the second frame 221. For example, referring to fig. 11 and 12, fig. 11 is a cross-sectional view of still another electronic device 10 in a folded position according to an embodiment of the present application, and fig. 12 is a partial cross-sectional view of the electronic device 10 shown in fig. 11, in which a support plate 224 is disposed in the second housing 221, and the support plate 224 is used to support the folding screen 100 so as to improve the flatness of the folding screen 100. The substrate 511 and the heat generating layer 512 may be disposed on a surface of the support plate 224 away from the second portion 120 of the folding screen 100, and the heat generating layer 512 is disposed between the substrate 511 and the support plate 224. In this way, the temperature generated by the heat-generating layer 512 may be transferred to the second portion 120 of the folding screen 100 through the support plate 224, thereby achieving heating of the second portion 120.

In another possible embodiment, the first heating element 510 may also be integrated into the folding screen 100, i.e. the first heating element 510 is integrated into the second portion 120 of the folding screen 100. For example, the first heating element 510 may include only the heat-generating layer 512 described above, and the heat-generating layer 512 is integrated within the second portion 120 of the folding screen 100 and electrically connected to the control circuit described above. In this way, the second portion 120 can be heated by the heat generating layer 512; on the other hand, the overall thickness of the electronic device 10 can be reduced.

In other embodiments, the first heating element 510 provided by embodiments of the present application may directly cover the second portion 120 of the folding screen 100, i.e., the first heating element 510 is provided only one and covers the display area of the second portion 120 of the folding screen 100. It is also possible to cover a local area on the second portion 120 of the folding screen 100 with one first heating element 510, for example, the first heating element 510 may cover only a region on the second portion 120 with a larger temperature difference (for example, a temperature difference exceeding 10 ℃) from the first portion 110, so as to avoid that the display color and the brightness on the folding screen 100 are greatly different due to the larger temperature difference, and influence the display effect.

Alternatively, a plurality of first heating elements 510 may be provided, and the plurality of first heating elements 510 may be distributed in a direction parallel to the second portion 120 of the folding screen 100, i.e., the plurality of first heating elements 510 may be provided corresponding to a plurality of localized areas of the second portion 120 of the folding screen 100.

Specifically, referring to fig. 13, fig. 13 is a diagram showing a temperature distribution diagram of a folding screen 100 of another electronic device 10 according to an embodiment of the present application, wherein a region with a temperature difference of more than 10 ℃ from a region a shown in fig. 6 is referred to as a low temperature region (as a region shown by a dashed box in fig. 13), and a plurality of low temperature regions are provided on a second portion 120 of the folding screen 100, so that a first heating element 510 may be provided corresponding to each low temperature region. In this way, the plurality of first heating elements 510 can be controlled to heat each low-temperature region respectively, so that the region with lower temperature on the folding screen 100 can be heated more accurately, the region with smaller temperature difference with the region a shown in fig. 6 on the folding screen 100 can be avoided from being heated, the overall temperature on the folding screen 100 can be more balanced, and the display effect of the folding screen 100 can be further improved.

For example, with continued reference to fig. 13, at two top corners of the second portion 120 of the folding screen 100 away from the first portion 110, namely, region B in the drawing, since the region B corresponds to the electronic component disposed in the space in the internal accommodating space (i.e., the second housing 221) and generates less heat or no electronic component is disposed, the temperature of the region B on the second portion 120 of the folding screen 100 is lower (e.g., 35 ℃), and therefore, the first heating element 510 shown in fig. 9 or 10 may be disposed in the second housing 221 corresponding to the two regions B. On one hand, the two areas B can be heated respectively, and on the other hand, the material is saved, and the overall cost is reduced. Meanwhile, other areas (the areas with smaller temperature differences with the area a shown in fig. 6) on the second portion 120 are not heated, so that the overall uniformity of the temperature of the folding screen 100 is further improved, and the display effect of the folding screen 100 can be further improved.

Referring now to fig. 14, therein is shown a block diagram of another electronic device 10 in accordance with the embodiment of the present application. The first portion 110 of the folded screen 100 may include a first area 111 and a second area 112, where a vertical projection of the soc chip 400 on the first portion 110 of the folded screen 100 is located in the first area 111, so as to further improve the uniformity of the overall temperature of the folded screen 100. The heating element 500 may further include a second heating element 520 (the first heating element 510 and the second heating element 520 are respectively shown in hatching in fig. 14), the second heating element 520 is disposed in the first frame 211, and a vertical projection of the second heating element 520 on the first portion 110 of the folding screen 100 is located in the second region 112. In this way, the second heating element 520 is disposed in the second frame 221, and the second area 112 on the first portion 110 of the folding screen 100 can be heated by the second heating element 520, so as to reduce the temperature difference between the first area 111 and the second area 112 of the first portion 110 of the folding screen 100, so that the temperatures of the areas of the first portion 110 of the folding screen 100 are more balanced, and the uniformity of the overall temperature of the folding screen 100 is further ensured.

The specific structure of the second heating element 520 and the installation manner in the first frame 211 are the same as those of the first heating element 510. Also, one second heating element 520 may be provided, and one second heating element 520 may cover the second region 112 of the first portion 110, or may cover a partial region of the second region 112; alternatively, the second heating element 520 may be provided in plural in the second region 112 of the first portion 110, so as to be capable of heating the regions of the second region 112 having a lower temperature. Therefore, a description thereof will not be repeated.

On this basis, in the electronic device 10 according to the embodiment of the present application, the first heating element 510 and the second heating element 520 may be controlled by the SoC chip 400 to be simultaneously energized to heat the corresponding area on the folding screen 100. Or may be separately controlled, that is, individual areas may be selectively heated according to the local temperature on the display 700.

For example, when the temperature of the first region 111 of the first portion 110 corresponding to the SoC chip 400 exceeds a preset temperature, for example, 45 ℃, the first heating element 510 and the second heating element 520 are controlled to be energized to generate heat, so as to heat the corresponding regions, thereby reducing the temperature difference between different regions of the folding screen 100.

Or, it may be set that when the temperature difference between the first area 111 of the first portion 110 and a certain area corresponding to the SoC chip 400 reaches a preset temperature difference, for example, the temperature difference between the first area 111 of the first portion 110 of the folded screen 100 and the second portion 120 of the folded screen 100 reaches 10 ℃, the first heating element 510 is controlled to be energized to generate heat, so as to heat the second portion 120 of the folded screen 100, so as to reduce the temperature difference between the second portion 120 and the first area 111 of the first portion 110, thereby ensuring the overall temperature balance of the folded screen 100.

When the first heating element 510 or the second heating element 520 is provided in plural, and the first heating element 510 and the second heating element 520 are provided in plural, it is possible to control all of the first heating element 510 and the second heating element 520 to be energized at the same time to generate heat. Alternatively, the first heating elements 510 and the second heating elements 520 may be controlled to be energized to generate heat, respectively, that is, some of the first heating elements 510 or some of the second heating elements 520 may be controlled to be energized to generate heat at the same time. The control logic may be adjusted according to the actual use requirements, and thus, embodiments of the present application are not limited in particular.

The electronic device 10 is a folding mobile phone, and the electronic device 10 is a bar mobile phone. Referring to fig. 15 and 16, fig. 15 is a block diagram of still another electronic device 10 according to an embodiment of the present application, and fig. 16 is an exploded view of the electronic device 10 shown in fig. 15.

Specifically, the electronic device 10 is a straight-plate mobile phone as shown in fig. 15, having an approximately rectangular plate-like structure. The electronic device 10 may include a second housing 600 and a display screen 700, where the second housing 600 may include a middle frame 610 and a rear case 620, the display screen 700 and the rear case 620 are respectively fixed on two sides of the middle frame 610, and the display screen 700, the middle frame 610 and the rear case 620 jointly enclose an internal accommodating space, and a main board 330, an SoC chip 400 and a third heating element 530 are disposed in the internal accommodating space, and the SoC chip 400 and the third heating element 530 are electrically connected with the main board 330.

Wherein, the vertical projection of the SoC chip 400 on the display screen 700 and the vertical projection of the third heating element 530 on the display screen 700 are offset from each other. With continued reference to fig. 16, and with continued reference to fig. 17, fig. 17 is a block diagram illustrating an area distribution manner on a display screen 700 of the electronic device 10 provided in fig. 15, where the display screen 700 has a third area 710 and a fourth area 720, a vertical projection of the soc chip 400 on the display screen 700 is located in the third area 710, and a vertical projection of the third heating element 530 on the display screen 700 is located in the fourth area 720.

In this way, the fourth area 720 of the display screen 700 can be heated by the third heating element 530, so that the temperature of the fourth area 720 of the display screen 700 is similar to the temperature of the third area 710, that is, the temperature difference between the fourth area 720 and the third area 710 of the display screen 700 is reduced, so that the whole temperature of the display screen 700 can be kept balanced, larger deviation of the color and brightness displayed in different areas of the display screen 700 is avoided, and the display effect of the display screen 700 is improved.

In some embodiments, the third heating element 530 may cover the entire fourth region 720, while ensuring that the temperatures of the fourth region 720 and the third region 710 remain balanced. Alternatively, only a local area on the fourth area 720 may be covered, for example, the temperature of the area of the fourth area 720 adjacent to the third area 710 is less different from the temperature of the third area 710, so that the third heating element 530 may not be provided, and only the area farther from the third area 710 may be provided with the third heating element 530, thereby being beneficial to saving materials and reducing costs.

For example, with continued reference to fig. 17, the fourth region 720 includes a sub-region 721 (the region shown by the dashed box in the figure), and since the sub-region 721 is far from the third region 710 and no electronic component with a large heat generation amount is present in the space corresponding to the sub-region 721, the temperature of the sub-region 721 in the fourth region 720 is low when the electronic device 10 is in operation, so that a large temperature difference is formed between the sub-region 721 and the third region 710. Based on this, the sub-area 721 may be heated by the third heating element 530, so that a temperature difference between the sub-area 721 and the third area 710 is reduced, so that the temperature of each area of the display screen 700 is kept balanced, and deviation of the color and brightness displayed by the display screen 700 in different areas is avoided.

In other embodiments, referring to fig. 18, fig. 18 is a block diagram illustrating another area distribution pattern on a display screen 700 of the electronic device 10 provided in fig. 15. The fourth region 720 may have a plurality of sub-regions 721 having a relatively low temperature, and thus, a plurality of third heating elements 530 may be disposed corresponding to the plurality of sub-regions 721 to heat each sub-region 721. In this way, on the one hand, each sub-area 721 can be heated separately to ensure that the overall temperature of the display screen 700 is balanced; on the other hand, the material of the third heating element 530 can be saved, which is beneficial to cost reduction.

In addition, the third heating element 530 has the same structure as the first heating element 510 and the second heating element 520 provided in the folding mobile phone, that is, the third heating element 530 includes the substrate 511 and the heat generating layer 512. The substrate 511 is fixed in the middle frame 610, and the heat generating layer 512 is disposed on the substrate 511. Also, the substrate 511 may be fixedly connected to the middle frame 610; or may be attached to the display 700; the substrate 511 may not be provided, and the heat generating layer 512 may be integrated in the display 700, which is the same as the folding mobile phone described above.

On this basis, in the straight mobile phone provided in this embodiment, the control manner and the distance for the third heating element 530 are the same as those of the folded mobile phone. Therefore, the description is not repeated.

In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.

The foregoing is merely illustrative of the present application, and the present application is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
