It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and do not limit the present disclosure.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.
In order to enable ordinary skilled people in the art to better understand the technical solution of the present disclosure, the technical solution of embodiments of the present disclosure will be clearly and completely described below in combination with the accompanying drawings.
It should be noted that the terms “first” and “second” in the description and claims of the present disclosure and the accompanying drawings are used to distinguish similar objects, and not be used to describe a specific order or sequence. It should be understood that the data such used can be interchanged where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein.

In related art, a technology of Mini LED backlight display adopts a large number of LED lights, resulting in huge heat, and temperature at a region of the display control chip may exceed a standard value. The traditional way is to use a heat dissipation diaphragm to physically dissipate the heat of the display control chip. Intelligent degree of temperature management is low and an effect of temperature control is poor.
To resolve the above-mentioned technical problems, in some embodiments of the present disclosure, temperature information of a target region of a display control chip is acquired, in which the display control chip is configured to control display of a display screen by controlling display of a LED light plate of a display module of an electronic device. The brightness of the display screen of the electronic device is adjusted according to the temperature information of the target region. Therefore, the present disclosure may monitor the temperature information of the target region of the display control chip, adjust the brightness of the display screen according to the monitored temperature information of the target region, so as to control the temperature of the target region and improve performance of temperature control of the device.
It is noted that the temperature at the region of the display control chip exceeding the standard value may be resulted by, on the one hand, heat produced by the display control chip during its own operation; on the other hand, heat of a LED light source external to the display control chip. In the present disclosure, after the temperature at the region of the display control chip exceeds the standard value, the brightness of the display screen of the electronic device is reduced, that is, the brightness of the LED light plate of the display module of the electronic device is reduced. Therefore, an effect of reducing the temperature may be achieved by reducing the heat of the LED light source external to the display control chip.

For another example, the main control chip 11 may calculate the temperature value of the target region according to the temperature value of the region where the timing control chip is located, the temperature value of the region where the backlight control chip is located and weight values occupied by the respective temperature values.
The main control chip 11 may adjust the brightness of the display screen according to the temperature information of the target region, which may include, but is not limited to, the following adjustment manners.
First adjustment manner: the temperature information may include a temperature value. It is determined whether the temperature value of the target region is greater than a preset temperature threshold value. The brightness of the display screen is reduced in response to the temperature value of the target region being greater than the preset temperature threshold value. The preset temperature threshold value may be, for example, 60° C. or 65° C. It is noted that a specific value of the preset temperature threshold value will not be limited in the preset disclosure, and may be adjusted according to the actual situation.
Second adjustment manner, the temperature information may include a temperature state. The brightness of the display screen may be reduced in response to the temperature state of the target region being a high temperature state. The temperature state of the target region is the high temperature state when the temperature value of the target region is greater than the preset temperature threshold value, and the temperature state of the target region is a normal temperature state when the temperature value of the target region is less than or equal to the preset temperature threshold value. It is noted that a specific value of the preset temperature threshold value will not be limited in the preset disclosure, and may be adjusted according to the actual situation.
In some embodiments, adjusting the brightness of the display screen may include, but is not limited to, the following brightness adjustment manners:
First brightness adjustment manner: the brightness of the display screen is reduced from a current brightness to brightness having a preset proportion to the current brightness.
Second brightness adjustment manner: brightness of a second region of the display screen corresponding to the target region is reduced. It is noted that the second region of the display screen corresponding to the target region refers to a region of the display screen corresponding to the display control chip. An area of the second region of the display screen may be slightly larger or smaller than that of the target region. For example, the area of the second region of the display screen may equal to the area of the target region. The area of the second region of the display screen may be adjusted according to the actual situation, which is not limited hereinafter.
Third brightness adjustment manner: a plurality of image frames played by the display screen within a preset time period is acquired, each image frame may include a plurality of pixels, and each pixel corresponds to one pixel region of the display screen. A plurality of voltage values of the pixel regions of the display screen corresponding to any pixel in the plurality of image frames are determined, any pixel is a pixel at a same position of the plurality of image frames. A target pixel is selected from the plurality of pixels, and the pixel region of the display screen corresponding to the target pixel is determined as a first region of the display screen, the target pixel may be a pixel that a variation range of the plurality of voltage values corresponding to the pixel meets a preset range. The brightness of the first region of the display screen is reduced.
In the first brightness adjustment manner, the brightness of the display screen is reduced from the current brightness to the brightness having the preset proportion to the current brightness. In an implementation manner, the brightness of the display screen may be directly reduced from the current brightness to the brightness having the preset proportion to the current brightness. For example, the brightness of the display screen may be directly reduced from the current brightness to 90% of the current brightness. In another implementation manner, the brightness of the display screen is reduced from the current brightness to the brightness having the preset proportion to the current brightness according to a preset speed of brightness reduction. For example, the brightness of the display may reduce the current brightness to 90% of the current brightness with a speed of reducing the current brightness by 1% every 5 seconds. In this brightness adjustment manner, reducing the overall brightness of the display screen may greatly reduce the heat dissipated by the entire LED light plate, and may control the temperature of the device to reduce rapidly.
In the second brightness adjustment manner, the brightness of the second region of the display screen corresponding to the target region is reduced. In an implementation manner, the brightness of the second region of the display screen is reduced from the current brightness to the brightness having the preset proportion to the current brightness. For example, the brightness of the second region of the display screen may be directly reduced from the current brightness to 90% of the current brightness. In another implementation manner, the second region of the display screen is located at a lower portion of the display screen, and the brightness of the second region of the display screen is gradually reduced from top to bottom. For example, a height of the second region of the display screen may be 30 mm, and the brightness of the second region of the display screen may sequentially reduce by 1% of the brightness of the previous region every 2 mm to 3 mm. When the second region of the display screen is located at the lower portion of the display screen, since the lower portion of the display screen is generally a region with less content displayed, the second brightness adjustment manner may be employed, which may ensure user experiences to the greatest extent.
In the third brightness adjustment manner, sixty image frames played by the display screen within 30 seconds are continuously acquired. The sixty image frames may be divided into the plurality of pixels, and each pixel point is located at the same position of the 60 image frames. The plurality of voltage values of the pixel regions of the display screen corresponding to each pixel in the sixty image frames may be determined. The variation range of the plurality of voltage values of each pixel may be calculated. In response to the variation range of the plurality of voltage values of each pixel being less than a preset range, it indicates that the pixel is an unimportant pixel, and the target pixel that the variation range of the plurality of voltage values corresponding to the pixel meets the preset range may be determined from the plurality of pixels, the content in the image frames corresponding to the target pixel is unimportant content, and the pixel region of the display screen corresponding to the target pixel is determined as the first region of the display screen, and the brightness of the first region of the display screen is reduced.
In some embodiments, the main control chip 11 adjusts the brightness of the display screen according to the temperature information of the target region. In an implementation manner, the main control chip 11 transmits a display brightness reduction instruction to the backlight control chip, to enable the backlight control chip to reduce the brightness of the display screen by controlling the brightness of the LED light plate to reduce according to the display brightness reduction instruction. For example, the main control chip 11 transmits the display brightness reduction instruction to the timing control chip, to enable the timing control chip to transmit the display screen brightness reduction instruction to the backlight control chip.
For example, an embedded controller of the main control chip 11 receives the temperature value of the target region transmitted by the temperature sensor. In response to the temperature value of the target region being greater than the preset temperature threshold value, the embedded controller transmits the display brightness reduction instruction to a GPU (graphics processing unit), and the GPU may transmit the display brightness reduction instruction to the timing control chip, and the timing control chip may transmit the display brightness reduction instruction to the backlight control chip. The backlight control chip may reduce the brightness of the display screen by controlling the brightness of the LED light plate to reduce according to the display brightness reduction instruction.
In some embodiments, the temperature sensor may be coupled to the main control chip 11 via a screen cable with a high-definition ultra-fine coaxial line. A connector of the screen cable with the high-definition ultra-fine coaxial line prepares unconnected pins for communication in advance, and is configured to establish a communication relationship between the temperature sensor and the main control chip 11.
