Fig. 1 illustrates a flowchart of a display screen control method according to an exemplary embodiment of the present disclosure.

In step S101, a first color temperature parameter acquired by the color temperature sensor is acquired.

The color temperature sensor is one of color sensors, can be formed by elements such as a photodiode and a voltage converter, and can obtain the color temperature parameter of the current ambient light through fitting by collecting visible light and invisible light in the environment. The first color temperature parameter represents a color temperature parameter of the current ambient light collected by the color temperature sensor.

In step S102, a color temperature compensation value is determined according to the current brightness parameter of the display screen and a first correspondence, and the first color temperature parameter is adjusted according to the color temperature compensation value to obtain a second color temperature parameter, where the first correspondence is used to represent the correspondence between the brightness parameter of the display screen and the color temperature compensation value.

The light leakage phenomenon of the display screen is caused by the overflow of a gap between a backlight source of the display screen and a crystal due to structural problems or tolerance, and the higher the brightness of the display screen is, the more serious the light leakage phenomenon is, so that the current light leakage degree of the display screen can be represented by the current brightness parameter (such as a Nib value) of the display screen. According to the current brightness parameter of the display screen and the corresponding relation between the brightness parameter of the display screen and the color temperature compensation value, the color temperature parameter generated by the light leakage rays under the condition that the display screen works with the current brightness parameter, namely the color temperature compensation value, can be determined. And obtaining a second color temperature parameter by removing the color temperature parameter generated by the light leakage light among the first color temperature parameters. The second color temperature parameter is a color temperature parameter generated by real ambient light after the first color temperature parameter is adjusted by the color temperature compensation value.

In step S103, the color temperature of the display screen is controlled according to the second color temperature parameter.

And controlling the color temperature of the display screen display picture according to the color temperature parameters generated by the real ambient light after adjustment. For example, under the condition that the ambient light is warm in color, the display screen can adjust the display picture to a warmth-bias tone, under the condition that the ambient light is cold in color, the display screen can adjust the display picture to a coolness-bias tone, so that the color appearance of the display screen presented to a user under different light environments is kept consistent, and the effect of true color display is achieved.

According to the method, the first color temperature parameter acquired by the color temperature sensor is compensated and adjusted through the acquired color temperature compensation value, and the color temperature of the display screen display picture is controlled through the second color temperature parameter acquired after compensation and adjustment, so that the terminal equipment can shield the influence of light leakage of the display screen on the environment color temperature, the display screen can adjust the color temperature of the display picture according to the real environment color temperature, and the reliability and user experience of a true color display function are improved.

In an alternative embodiment, the first color temperature parameter includes sub-parameters of a plurality of channels;

Determining a color temperature compensation value according to the current brightness parameter of the display screen of the terminal equipment and the first corresponding relation, and adjusting the first color temperature parameter according to the color temperature compensation value to obtain a second color temperature parameter, wherein the method comprises the following steps:

optionally, the color temperature parameters may be obtained by C, R, G, B, W channels of the color temperature sensor, where the color temperature parameters of the three-color light source are obtained through RGB channels, the color temperature parameters of the white light are obtained through W channels, and the total color temperature parameters of the three-color light source and the invisible light source are obtained through C channels. In the five channels, the subparameter of each channel is influenced by the light leakage of the display screen, and the influence degree of the light leakage phenomenon on each color temperature parameter under the condition that the display screen works with the current brightness parameter can be determined by respectively acquiring the color temperature compensation value corresponding to each subparameter of the five channels.

Optionally, the sub-parameters of each channel in the first color temperature parameters are adjusted to obtain the adjusted sub-parameters of each channel, namely the second color temperature parameters.

According to the method, the sub-parameters of each channel in the first color temperature parameters acquired by the color temperature sensor are compensated and adjusted through the acquired color temperature compensation value, so that accurate compensation and adjustment of the color temperature result acquired by the color temperature sensor are realized.

in step S201, in a preset calibration environment, a color temperature parameter acquired by the color temperature sensor when the display screen displays a picture with a preset luminance parameter, and a luminance parameter of the display screen when the color temperature parameter acquired by the color temperature sensor is the preset color temperature parameter are acquired.

The calibration process can be performed through the most each terminal device in the device production stage to obtain a first corresponding relationship of each terminal device, namely, a corresponding relationship between the brightness parameter of the display screen and the color temperature compensation value. In an example, the preset calibration environment may be implemented by a black box, where the black box is made of a black opaque material with low reflectivity, and is used to shield ambient light and influence of screen brightness of the display screen on the color temperature sensor, so that the color temperature sensor can only obtain the color temperature parameter by using light leakage light of the display screen.

And under the preset calibration environment, displaying a picture by the display screen through a preset brightness parameter, so that the color temperature parameter acquired by the color temperature sensor is used for representing the color temperature parameter of light leakage rays under the condition that the light leakage phenomenon of the display screen is serious, wherein the preset brightness parameter can be the highest brightness parameter which can be achieved by the display screen. And then, acquiring the brightness parameter of the display screen when the color temperature parameter acquired by the color temperature sensor is a preset color temperature parameter. The brightness parameter is used for representing the brightness parameter of the display screen under the condition that light leakage cannot influence the color temperature sensor. In one example, 0 may be used as the preset color temperature parameter, where the color temperature of the leaked light cannot be collected by the color temperature sensor, and the influence of the leaked light on the color temperature sensor is minimal.

In step S202, the first correspondence is determined according to a preset luminance parameter of the display screen, a color temperature parameter acquired by the color temperature sensor when the display screen displays a picture with the preset luminance parameter, and a luminance parameter of the display screen when the color temperature parameter acquired by the color temperature sensor is the preset color temperature parameter.

Optionally, the corresponding relation between the brightness parameter of the display screen and the color temperature compensation value can be determined through the color temperature parameter of the light leakage light under the condition that the light leakage phenomenon of the display screen is the worst and the brightness parameter of the display screen under the condition that the light leakage phenomenon does not influence the color temperature sensor. In one example, a model using the luminance parameter of the display screen as an independent variable and the color temperature parameter collected by the color temperature sensor as a dependent variable may be constructed, and the linear correspondence between the luminance parameter of the display screen and the color temperature parameter, that is, the first correspondence, may be determined according to the luminance parameter of the display screen when the luminance parameter of the display screen is the preset luminance parameter and the color temperature parameter is the preset color temperature parameter. According to the first corresponding relation, the color temperature parameter of the display screen light leakage light rays collected by the color temperature sensor when the display screen works with any brightness parameter, namely the color temperature compensation value, can be determined.

In one example, the color temperature parameters collected by the color temperature sensor include sub-parameters of the plurality of channels.

Likewise, when the display screen displays a picture with preset brightness parameters, the subparameter of each channel in the color temperature parameters collected by the color temperature sensor and the brightness parameters of the display screen when the subparameter of each channel in the color temperature parameters collected by the color temperature sensor are respectively preset color temperature parameters can be obtained, and models with the brightness parameters of the display screen as independent variables and the subparameter of each channel in the color temperature parameters as dependent variables are respectively constructed.

In the case that the color temperature sensor obtains the sub-parameters through the five C, R, G, B, W channels, the linear correspondence between the brightness relationship of the display screen and each sub-parameter, that is, the first correspondence between the sub-parameters of each channel, may be determined based on the above method. According to the first correspondence, a sub-parameter of each channel in the color temperature parameters of the display screen light leakage rays collected by the color temperature sensor when the display screen works with any brightness parameter, namely the color temperature compensation value, can be determined.

According to the method, through determining the color temperature change caused by the light leakage phenomenon caused by the brightness parameter of the display screen in the preset calibration environment, the first corresponding relation is determined, so that each terminal device can determine the specific first corresponding relation according to the actual light leakage degree, and the first color temperature parameter can be adjusted in a personalized mode in the follow-up process. In addition, by determining the first corresponding relation of the sub-parameters of each channel, the accuracy of the obtained compensation adjustment parameters is improved, and therefore the reliability of the second color temperature parameters is improved.

In an optional embodiment, the acquiring, in a preset calibration environment, the color temperature parameter acquired by the color temperature sensor when the display screen displays the picture with the preset brightness parameter includes:

For a display screen composed of a backlight source and a liquid crystal material, such as an LCD (liquid crystal screen), in a state of displaying a pure white image card, i.e. a white image, with a preset brightness, the liquid crystal material does not need to change the arrangement condition of internal molecules, and under the condition that a gap exists between the backlight source and a crystal, the light leakage phenomenon reaches the most serious degree, so that the state of displaying the white image with the preset brightness parameter of the display screen can be used as the same state of displaying a picture with the preset brightness parameter of the display screen, and likewise, the preset brightness parameter can be the highest brightness parameter which can be achieved by the display screen.

According to the method disclosed by the disclosure, the display screen is controlled to display the white image with the preset brightness parameter, so that the terminal equipment is in the most serious light leakage state, and the color temperature parameter acquired by the color temperature sensor is acquired at the moment, so that the color temperature parameter of light leakage light rays under the most serious light leakage phenomenon of the display screen can be accurately determined.

In an optional embodiment, the acquiring the luminance parameter of the display screen when the color temperature parameter acquired by the color temperature sensor is a preset color temperature parameter includes:

and controlling the display screen to gradually reduce the brightness parameter by taking the preset brightness parameter as an initial parameter, and acquiring the brightness parameter of the display screen when the color temperature parameter acquired by the color temperature sensor is the preset color temperature parameter.

Optionally, after the color temperature parameter of the light leakage light ray under the condition that the light leakage phenomenon of the display screen is the worst is obtained, the brightness of the display screen can be gradually detected by reducing the brightness of the display screen, and when the color temperature parameter is a preset color temperature parameter, the brightness parameter is determined, that is, the brightness parameter of the display screen under the condition that the light leakage phenomenon does not influence the color temperature sensor is determined. If the color temperature parameters acquired by the color temperature sensor include sub-parameters of a plurality of channels, the brightness parameters of the display screen when each sub-parameter reaches the preset color temperature parameters can be sequentially acquired in the downward detection process of the brightness parameters.

According to the method, the brightness parameters of the display screen are obtained by gradually reducing the brightness parameters to the preset color temperature parameters, so that the brightness parameters of the display screen under the condition that the light leakage phenomenon does not influence the color temperature sensor are accurately obtained.

In an alternative embodiment, after determining the first correspondence, the method further comprises:

and storing the first corresponding relation to a persistent partition of the terminal equipment.

Optionally, the persistent partition (persistent partition) can guarantee persistent storage of data in the terminal device. Because the light leakage degree of each terminal device under the same brightness parameter is different, if the first corresponding relation is lost, the first corresponding relation can only be obtained through recalibration, and inconvenience is brought to users. Therefore, after the first corresponding relation is obtained in the production line, the first corresponding relation and basic data such as Bluetooth and camera calibration data of the terminal equipment can be stored in the persistent partition together, so that the loss of the first corresponding relation caused by a user formatting or reloading system is prevented.

Optionally, before the terminal device needs to obtain the first correspondence to determine the color temperature compensation value, the first correspondence pre-stored in the persistent partition in the production line calibration process may be obtained, so as to facilitate subsequent adjustment of the first color temperature parameter.

According to the method, the first corresponding relation is stored to the persistent partition of the terminal equipment in the calibration stage of the production line, so that the loss of the first corresponding relation caused by user formatting or reinstalling a system is prevented.

In an optional embodiment, the determining a color temperature compensation value according to the current brightness parameter of the display screen of the terminal device and the first correspondence, and adjusting the first color temperature parameter according to the color temperature compensation value, to obtain a second color temperature parameter, includes:

Optionally, the first color temperature parameter includes a real color temperature parameter of the ambient light and a color temperature parameter of the leaked light of the display screen, and under the condition that the ambient light is stronger, the higher the ratio of the real color temperature parameter of the ambient light in the first color temperature parameter is, the smaller the influence of the light leakage phenomenon on the true color display of the display screen is. Therefore, an ambient brightness threshold value can be set, and when the ambient light brightness parameter is larger than the ambient brightness threshold value, compensation adjustment of the first color temperature parameter is stopped so as to reduce the operation pressure of the terminal equipment.

And under the condition that the ambient light is weaker, the ratio of the color temperature parameter of the light leakage light of the display screen to the first color temperature parameter is increased, the influence of the light leakage phenomenon on true color display of the display screen is increased, and under the condition that the ambient light brightness parameter is smaller than the brightness threshold, the compensation adjustment process of the first color temperature parameter can be started, so that the display screen can adjust the color temperature of a display screen according to the real ambient color temperature, and the reliability and user experience of the true color display function are improved.

According to the method, the ambient brightness threshold value is set, compensation adjustment of the first color temperature parameter is stopped under the condition that the ambient light brightness parameter is larger than the ambient brightness threshold value so as to reduce the operation pressure of the terminal equipment, and the compensation adjustment process of the first color temperature parameter is started under the condition that the ambient light brightness parameter is smaller than the ambient brightness threshold value, so that the display screen can adjust the color temperature of a display picture according to the real ambient color temperature, and the reliability and user experience of a true color display function are improved.

In an alternative embodiment, the color temperature sensor is located in a narrow slit at the edge of the screen of the terminal device.

Currently, the color temperature sensor is usually arranged below a crystal of a display screen, and for the display screen with a light leakage phenomenon, the color temperature sensor is easier to collect color temperature parameters of light leakage rays due to the arrangement mode, and the color temperature sensor is arranged in a narrow slit at the edge of a screen of the terminal equipment, so that the color temperature sensor is not easy to collect the color temperature parameters of the light leakage rays by mistake, and the influence of the light leakage phenomenon on the color temperature sensor is reduced.

According to the method, the color temperature sensor is arranged in the narrow slit at the edge of the screen of the terminal equipment, so that the influence of the light leakage phenomenon on the color temperature sensor is further avoided.
