Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the invention shown in the drawings and described in accordance with the drawings are merely exemplary and the invention is not limited to these embodiments.
It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and/or processing steps that are closely related to the solution according to the present invention are shown in the drawings, and other details that are not relevant are omitted.
Referring to fig. 1, the present embodiment provides a method for controlling current radiation of a mobile terminal, including:
s1, controlling current radiation to be concentrated in a first area on a display screen of a mobile terminal;
s2, detecting the temperature of the first area;
s3, judging whether the temperature of the first area is larger than a preset temperature or not, if so, controlling the current radiation of the first area to diffuse to a second area of the display screen, wherein the area of the second area is larger than that of the first area.
In the method for controlling current radiation of the mobile terminal, when current radiation is concentrated on a certain region (referred to as a first region in this embodiment) on the display screen as usual, the temperature of the region is monitored, and if the temperature of the region is detected to be too high and higher than a preset temperature, the current radiation distributed in the region is controlled to be diffused to another region (referred to as a second region in this embodiment, the second region includes the first region) with a larger area, so that the current radiation on the first region is uniformly distributed to the second region with a larger area, and the temperature on the first region is reduced, thereby preventing the first region of the display screen from being damaged due to the influence of high temperature.
Specifically, the method for controlling the diffusion of current radiation onto the second area of the display screen comprises the following steps: equally dividing the current radiation into a plurality of groups, and diffusing the plurality of groups of current radiation to a second area of the display screen in sequence. The current radiation is divided into a plurality of groups to be sequentially diffused to the second area of the display screen, namely, the heat radiated by the current is diffused to the second area of the display screen in a grading manner, the temperature of the second area is gradually increased, the heat dissipation of the second area is facilitated, and the phenomenon that the temperature of the second area is instantly increased to cause the damage of the whole second area due to high temperature is avoided.
Specifically, in step S3, it is determined whether the temperature of the first area is greater than a preset temperature, and if so, the current radiation of the first area is controlled to diffuse toward the edge of the second area of the display screen. The diffusion from the center of the second region to the edge of the second region can extend the diffusion path and further lower the temperature at the center of the second region.
As shown in fig. 2, since the mobile terminal generates a large current radiation when operating for a long time, the temperature of the first area may still be higher than a safe range value after the current radiation of the first area is diffused to the second area, and even after the current radiation is diffused to the second area, other areas on the second area may be damaged by the high temperature, further, as another embodiment of the current radiation control method, the second area includes a plurality of sub-areas, and the current radiation method further includes:
s4, respectively detecting the temperature of each sub-area of the second area;
and S5, respectively judging whether the temperature of each sub-area is greater than a preset temperature, if so, controlling the radiation of the sub-area with the temperature greater than the preset temperature to diffuse to the whole second area, and executing the step S4 and the step S5 again in sequence.
By executing the step S4 and the step S5, the temperature of each sub-area on the second area can be monitored in real time, and when the temperature of some sub-areas including the first area in the second area is higher than the preset temperature, the radiation on the areas is diffused to the whole second area again, so that the temperature distribution on the second area is further homogenized, the temperature of the abnormal sub-areas is reduced, and the damage caused by high temperature is avoided.
In this embodiment, the first region is a single sub-region.
In this embodiment, the second area is an area occupied by the display screen. The whole area of the display screen is used as the second area, so that the current radiation on the first area can be dispersed to the maximum extent, and the temperature of the first area is reduced to the maximum extent in the secondary diffusion.
The preset temperature is a temperature threshold set according to user requirements, and is used for judging whether the display screen is burnt or not according to whether the temperature on the area is higher than the preset temperature or not, so that the preset temperature is set to be different values according to different factors such as heat resistance of materials, size of the display screen, and working environment of the display screen in practical application. For example, in the present embodiment, the preset temperature is 70 ℃.
The spreading of the current radiation can be achieved, for example, by controlling the current lines with different routing profiles or by using heat-conducting sheets covering different areas. For example: the method comprises the steps that through a first current line arranged in the first area for wiring and a second current line arranged in the second area for wiring, whether the first current line is conducted with the second current line or not is controlled through a switch to achieve radiation diffusion of current in the first area to the second area, namely in step S1, the connection between the first current line and the second current line is disconnected through switch control to control the current radiation to be concentrated in the first area on a display screen of the mobile terminal, and in step S3, if the temperature of the first area is larger than a preset temperature, the first current line and the second current line are conducted through the switch control to control the current radiation diffusion of the first area to the second area of the display screen; for another example, a heat conducting sheet covering the second area may be provided, and a switch is used to control whether the first area is connected to the heat conducting sheet, and heat dissipation is performed by the heat conducting sheet contacting the first area, so as to implement diffusion of the current radiation, in step S1, the connection between the first area and the heat conducting sheet is disconnected through the switch control, so as to control the current radiation to be concentrated on the first area on the display screen of the mobile terminal, and in step S3, if the temperature of the first area is greater than a preset temperature, the first area and the heat conducting sheet are connected through the switch control, so as to control the current radiation of the first area to be diffused to the second area of the display screen.
An embodiment of the present invention further provides a computer storage medium, where a current radiation program is stored on the computer storage medium, and the current radiation program is used for being executed by a processor to implement the current radiation control method described above.
The embodiment of the invention also provides a mobile terminal, which comprises a memory, a processor and a control program of current radiation, wherein the control program of current radiation is stored on the memory and can be operated on the processor, and the control program of current radiation is used for being executed by the processor to realize the control method of current radiation.

In summary, the mobile terminal, the current radiation control method thereof, and the computer storage medium provided in the embodiments of the present invention monitor the temperature of the first area where the current radiation is concentrated on the display screen, and if it is detected that the temperature of the first area is higher than the preset temperature, control the current radiation distributed in the first area to diffuse to the second area with an area larger than that of the first area, so as to reduce the temperature of the first area, thereby preventing the first area of the display screen from being damaged due to the influence of high temperature. And the control method can continuously monitor the temperature of each sub-area on the second area in real time, and when the temperature of some sub-areas in the second area is higher than the preset temperature, the radiation on the sub-areas is diffused to the whole second area again, so that the temperature distribution on the second area is further homogenized, and the risk of the display screen being damaged by high temperature is further reduced.
