The present application provides a display device 10. Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a top view of a display device according to an embodiment of the application; FIG. 2 is a schematic cross-sectional view taken along line A-A in FIG. 1; fig. 3 is an enlarged partial schematic view at I in fig. 2. In this embodiment, the display device 10 includes a carrier substrate 11. The carrier substrate 11 has a carrier surface 111. The carrier substrate 11 further has a plurality of preset regions 112. The display device 10 further includes a cooling assembly 12, a plurality of light emitting assemblies 14, and a processor 15. The light emitting elements 14 are disposed in the preset areas 112 at intervals, and at least one light emitting element 14 is disposed in one preset area 112. The light emitting assembly 14 includes a light emitting element 141 and a temperature sensor 142, and the light emitting element 141 is disposed on the supporting surface 111. The temperature sensor 142 is used to detect the current temperature of the light emitting element 141. The processor 15 is electrically connected to the temperature sensor 142 and the cooling component 12, and is configured to receive a plurality of the current temperatures, mark a preset area 112 with an average value or a maximum value of the current temperatures being greater than or equal to a preset threshold value as an area to be cooled, and control the cooling component 12 to cool the light emitting element 141 in the area to be cooled.

In the present embodiment, the display device 10 is widely used in various electronic apparatuses 1, such as mobile phones, tablet computers, notebook computers, palm computers, personal computers (Personal Computer, PC), personal digital assistants (Personal Digital Assistant, PDA), and the like.

In this embodiment, the carrier substrate 11 has a plurality of preset regions 112, and the plurality of light emitting elements 14 are disposed at intervals in the plurality of preset regions 112. In each of the light emitting assemblies 14, the temperature sensor 142 is used to detect the current temperature of the light emitting element 141. The processor 15 receives all the current temperatures, determines the average value or the maximum value of the current temperatures of all the light emitting elements 141 in each preset area 112 and the preset threshold value, marks the preset area 112 with the average value or the maximum value of the current temperatures being greater than or equal to the preset threshold value as an area to be cooled, and controls the cooling component 12 to cool the light emitting elements 141 in the area to be cooled, so as to realize targeted area cooling, namely intelligent cooling.

Optionally, each preset area 112 is provided with the same number or different numbers of the light emitting assemblies 14, and a corresponding number of the light emitting assemblies 14 may be set in different preset areas 112 according to actual working requirements, that is, different numbers of the light emitting assemblies 14 may be divided into different preset areas 112 according to actual working requirements. For example, the plurality of cooling components 12 that are prone to generate heat are divided into the same preset area 112 to improve the cooling quality of the display device 10; alternatively, in the case where the area of the display device 10 prone to heat generation is smaller, a larger number of the preset areas 112 may be divided, that is, one preset area 112 includes a smaller number of the light emitting assemblies 14, so that the light emitting elements 141 can be cooled more specifically, and the display device 10 can be cooled more intelligently.

Alternatively, in an embodiment, the temperature sensor 142 is stacked with the light emitting element 141, and the temperature sensor 142 is disposed in the carrier substrate 11, so as to reduce the influence of the temperature sensor 142 on the display of the display device 10. In another embodiment, the temperature sensor 142 is disposed on the carrying surface 111 and adjacent to the light emitting element 141, so that the assembly of the temperature sensor 142 is simpler.

Alternatively, the preset threshold may be set according to the actual working environment and the working requirement of the display device 10, which is not limited herein. In addition, the preset threshold value corresponding to each preset region 112 may be the same or different. If the temperature at which the light emitting element 141 of the display device 10 can operate in each preset area 112 is the same, the preset threshold value corresponding to each preset area 112 may be set to be the same. If there are different temperatures in the display device 10 at which the light emitting elements 141 in the different preset regions 112 operate normally, the preset threshold values corresponding to the different preset regions 112 may be set to be different.

Optionally, in an embodiment, the cooling component 12 cools the light emitting element 141 in the area to be cooled through a cooling liquid, so that the cooling efficiency is high, and the cooling device is environment-friendly. In another embodiment, the cooling component 12 cools the light emitting element 141 in the area to be cooled by blowing air, and the cooling manner is simple and quick.

In summary, the present application provides a display device 10, the carrier substrate 11 of the display device 10 has a plurality of preset areas 112, the temperature sensor 142 detects the current temperature of the light emitting element 141, the processor 15 is configured to receive the current temperature in each preset area 112 and compare the current temperature with the preset threshold, the processor 15 marks the preset area 112 with the average value or the maximum value of the current temperature being greater than or equal to the preset threshold as an area to be cooled, and controls the cooling component 12 to cool the light emitting element 141 in the area to be cooled, so as to implement intelligent cooling. Therefore, the display device 10 provided by the application can identify the region to be cooled and intelligently cool the region to be cooled.

Referring to fig. 1, 2, 3 and 4, fig. 4 is a schematic diagram illustrating a distribution of cooling channels of the display device in fig. 1. In the present embodiment, the carrier substrate 11 has a liquid storage space 113 and a cooling channel 114. The liquid storage space 113 stores a cooling liquid, and the liquid storage space 113 has a plurality of liquid outlets 1131. The cooling channel 114 is arranged on the side of the temperature sensor 142 facing away from the light-emitting element 141. The cooling channel 114 includes a plurality of cooling sub-channels 1141. One cooling sub-channel 1141 is connected to one liquid outlet 1131, different cooling sub-channels 1141 are connected to different liquid outlets 1131, and different cooling sub-channels 1141 are disposed in different preset areas 112. The cooling assembly 12 is configured to drive the cooling liquid in the liquid storage space 113 to the cooling sub-channel 1141 corresponding to the region to be cooled under the control of the processor 15.

In this embodiment, the cooling module 12 cools the light emitting element 141 in the area to be cooled by the cooling liquid stored in the liquid storage space 113, and the cooling liquid can be recycled, so that the cooling by using the cooling liquid is environment-friendly.

In this embodiment, different cooling sub-channels 1141 are disposed in different preset areas 112 to achieve targeted area cooling. One cooling sub-channel 1141 communicates with one liquid outlet 1131, and different cooling sub-channels 1141 communicate with different liquid outlets 1131, i.e., no other communication path exists between different cooling sub-channels 1141. Specifically, when the cooling module 12 drives the cooling liquid in the liquid storage space 113 to the cooling sub-passage 1141 corresponding to the region to be cooled under the control of the processor 15, the cooling liquid flows only in the cooling sub-passage 1141 corresponding to the region to be cooled, and does not flow into the other cooling sub-passages 1141.

Alternatively, the cooling liquid may be, but not limited to, an alcohol-type cooling liquid, or a glycerin-type cooling liquid, or an ethylene glycol-type cooling liquid, or a propylene glycol-type cooling liquid, or water, etc., as long as it can perform a cooling function.

Optionally, the carrier substrate 11 includes a first substrate and a second substrate. The first substrate has the carrying surface 111 for carrying the light emitting element 141. The temperature sensor 142 is provided in the first substrate, and the temperature sensor 142 and the light emitting element 141 are stacked. The second substrate has a receiving space, and the receiving space includes the liquid storage space 113. The accommodating space is used for accommodating the cooling assembly 12. The second substrate is disposed on a side of the first substrate facing away from the light emitting element 141. The second substrate is connected with the first substrate in a matched mode to seal the accommodating space. The first substrate and the second substrate are cooperatively connected to form the bearing substrate 11, which is beneficial to the installation of the cooling assembly 12.

The cooling channel 114 is disposed in the first substrate, or the cooling channel 114 is disposed in the second substrate, or the cooling channel 114 is formed at a connection position between the first substrate and the second substrate after the first substrate is connected with the second substrate in a matching manner.

Further, in the arrangement direction of the plurality of light emitting elements, the thickness of the second substrate is uniformly distributed, so that the second substrate is simple to manufacture; alternatively, the thickness of the second substrate at the cooling channel 114 is smaller than the thickness at the cooling module 12 in the arrangement direction of the plurality of light emitting elements, which is beneficial to reducing the manufacturing cost of the display device 10.

Referring to fig. 4, 5, 6 and 7, fig. 5 is a schematic view of a portion of the cooling device shown in fig. 2; FIG. 6 is a schematic view of a first rotating disk of the display device of FIG. 2; fig. 7 is a schematic structural view of a second rotating disc of the display device of fig. 2. In the present embodiment, the cooling unit 12 includes a first rotary disk 121, a first driving motor 122, and a second rotary disk 123. The first rotating disc 121 has an opening 1211 and a reservoir 1212 in communication therewith. The liquid storage tank 1212 is communicated with the liquid storage space 113 for storing the cooling liquid. The first driving motor 122 is used for driving the opening 1211 of the first rotating disk 121 to align with the liquid outlet 1131 communicated with the cooling sub-channel 1141 corresponding to the region to be cooled under the control of the processor 15. The second rotating disk 123 has a boss 1231. The boss 1231 is configured to matingly couple with the reservoir 1212. With the opening 1211 aligned with the liquid outlet 1131 and the protruding portion 1231 cooperatively connected with the liquid storage tank 1212, the first driving motor 122 drives the second rotating disc 123 to rotate relative to the first rotating disc 121 under the control of the processor 15. The protrusion 1231 presses the cooling liquid in the liquid storage tank 1212 to the cooling sub-channel 1141 corresponding to the region to be cooled through the opening 1211.

In this embodiment, after the processor 15 marks the preset area 112 with the average value or the maximum value of the current temperature being greater than or equal to the preset threshold value as the area to be cooled, the processor 15 controls the first driving motor 122 to drive the opening 1211 of the first rotating disc 121 to align with the liquid outlet 1131 communicated with the cooling sub-channel 1141 corresponding to the area to be cooled. Then, with the protruding portion 1231 being cooperatively connected with the liquid storage tank 1212, the processor 15 controls the second rotating disc 123 to rotate relative to the first rotating disc 121, so as to squeeze the cooling liquid in the liquid storage tank 1212 to the cooling sub-channels 1141 corresponding to the region to be cooled through the protruding portion 1231. The cooling liquid is extruded to the cooling sub-channels 1141 corresponding to the region to be cooled by extrusion, and the cooling mode is simple and easy to control.

Optionally, the first rotating disc 121 has two openings 1211, and the first rotating disc 121 is disposed on a transverse resistance shaft between the openings 1211, when the liquid outlets 1131 communicated with the cooling sub-channels 1141 corresponding to the to-be-cooled area are two liquid outlets disposed at intervals or in communication, the transverse resistance shaft is aligned with the two liquid outlets, and one opening 1211 is disposed corresponding to one liquid outlet, so that the second rotating disc 123 rotates anticlockwise or clockwise relative to the first rotating disc 121, and can both squeeze the cooling liquid in the liquid storage tank 1212 to the cooling sub-channel 1141 corresponding to the to-be-cooled area. When the liquid outlet 1131, which is communicated with the cooling sub-channel 1141 corresponding to the region to be cooled, is a through hole, any one of the two openings 1211 may be aligned with the liquid storage port.

Alternatively, the first driving motor 122 is a stepping motor, so that the first rotating disc 121 and the second rotating disc 123 have stable movement and high movement accuracy.

Referring to fig. 5, fig. 6, fig. 7, fig. 8 and fig. 9, fig. 8 is an enlarged partial schematic view of the mating connection between the first mating portion and the third mating portion at II in fig. 5; fig. 9 is an enlarged partial schematic view of the mating connection between the second mating portion and the third mating portion in fig. 5 at II. In the present embodiment, the first rotating disc 121 has a first engaging portion 1213, and the second rotating disc 123 has a second engaging portion 1232. The cooling assembly 12 also includes a central spindle 124. The central rotating shaft 124 is connected to the first driving motor 122. The central rotating shaft 124 is disposed through the first rotating disc 121 and the second rotating disc 123. The central shaft 124 has a third mating portion 1241. The third mating part 1241 is used for mating connection with the first mating part 1213 or the second mating part 1232. When the third mating portion 1241 is mated with the first mating portion 1213, the first driving motor 122 drives the central rotating shaft 124 to rotate, so as to drive the first rotating disc 121 to rotate, so that the opening 1211 is aligned with the liquid outlet 1131. When the third mating portion 1241 is mated with the second mating portion 1232, the protruding portion 1231 is mated with the liquid storage tank 1212, and the first driving motor 122 drives the central rotating shaft 124 to rotate, so as to drive the second rotating disk 123 to rotate relative to the first rotating disk 121, so as to squeeze the cooling liquid in the liquid storage tank 1212 to the cooling sub-channel 1141 corresponding to the region to be cooled through the opening 1211.

In this embodiment, the third mating part 1241 is mated with the first mating part 1213 or the second mating part 1232, that is, the third mating part 1241 is not mated with the first mating part 1213 and the second mating part 1232 at the same time. When the third mating portion 1241 is mated with the first mating portion 1213 (see fig. 8), the first driving motor 122 drives the central rotating shaft 124 to rotate so as to drive the first rotating disc 121 to rotate, so that the opening 1211 is aligned with the liquid outlet 1131. When the third mating portion 1241 is mated with the second mating portion 1232 (see fig. 9), the protruding portion 1231 is also mated with the liquid storage tank 1212, and the first driving motor 122 drives the second rotating disk 123 to rotate clockwise or counterclockwise compared with the first rotating disk 121, so as to squeeze the cooling liquid in the liquid storage tank 1212 to the cooling sub-channel 1141 corresponding to the region to be cooled, so as to cool the light emitting element 141 in the region to be cooled. In this embodiment, the third mating portion 1241 is mated with the first mating portion 1213 and the second mating portion 1232 in sequence according to a preset sequence, so as to align the opening 1211 with the liquid outlet 1131, and then squeeze the cooling liquid, thereby cooling the region to be cooled.

Referring again to fig. 5, 6, 7, 8 and 9, in the present embodiment, the cooling unit 12 further includes a second driving motor 125 and a third driving motor 126. The second driving motor 125 is connected to the first rotating disc 121.
