detailed description

Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, and are only for explaining the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

Please refer to Fig. 1-4, the control method of the embodiment of the present invention is used to control the brightness of the display screen 130, the display screen 130 includes a pixel array 131; the pixel array 131 includes a plurality of pixel groups 1311, and each pixel group 1311 includes a plurality of pixels; control methods include:

S1, determine the number of display pixels 1313 and the number of pixels to be displayed 1314 of each pixel group 1311 according to the target brightness; and

S2, turn off the pixel 1314 to be displayed.

In the control device 110 in the embodiment of the present invention, the control device 110 includes a determination module 111 and a closing module 112, which can be used to realize S1 and S2 respectively. That is, the determination module 111 is used to determine the number of display pixels 1313 and the number of display pixels 1314 of each pixel group 1311 according to the target brightness, and the shutdown module 112 is used to turn off the display pixels 1314 .

The control device 110 in the embodiment of the present invention can be applied to the electronic device 100 in the embodiment of the present invention.

Please refer to FIG. 3 , in some embodiments, the electronic device 100 includes a mobile phone or a tablet computer. The electronic device 100 may include a light sensor 150 or an imaging device 170 for sensing ambient brightness. The imaging device 170 may be a camera.

Since the pupil of the human eye adjusts its size with the change of the ambient brightness, when the pupil is opened in a rather dark environment, or when it suddenly changes from a bright environment to a dark environment, if the display screen 130 is too bright, it will feel dazzling and uncomfortable. Long-term use will also cause certain damage to human eyes. In the embodiment of the present invention, the pixels are divided into a plurality of pixel groups 1311, and by turning off some pixels in the pixel groups 1311, that is, the pixels to be displayed 1314, the brightness of the display screen can be quickly lowered, so as to avoid the human eye Discomfort, helps to protect the eyes.

Due to the high resolution of the general display screen 130 and the large number of pixels, the pixel group 1311 can be composed of several adjacent pixel groups 1311, and each pixel group 1311 turns off one or several pixels, and the display screen 130 can still display the original display. Content.

The number of pixels 1314 to be displayed in the pixel group 1311 can be determined according to the target brightness. For example, the lower the target brightness is, the larger the number of pixels 1314 to be displayed is, that is to say, the greater the range of brightness reduction, so that the brightness of the display screen after turning off the pixels 1314 to be displayed reaches or approaches the target brightness.

Please refer to FIG. 5 , in some implementations, the number of each pixel 1314 to be displayed corresponds to a brightness range; S1 determines the corresponding number of pixels 1314 to be displayed according to the brightness range where the target brightness is located. In some implementations, the determination module 111 of the control device 110 is configured to determine the corresponding number of pixels 1314 to be displayed according to the brightness range where the target brightness is located.

For example, the target brightness is divided into several ranges from high to low, when the target brightness is in the first range (i.e. the range with the highest brightness value), it is determined that the number of pixels 1314 to be displayed is 0, that is, no pixel is turned off; when the target brightness is in the first range In the second range, determine that the number of pixels 1314 to be displayed is 1, that is, each pixel group 1311 turns off 1 pixel; when the target brightness is in the third range, determine that the number of pixels 1314 to be displayed is 2, that is, each pixel group 1311 turns off 2 pixels...and so on. It is worth noting that the number of pixels 1314 to be displayed in the pixel group 1311 should be less than the total number of pixels in the pixel group 1311, that is, the display pixel 1313 is greater than or equal to 1, so as to ensure that at least one pixel in the pixel group 1311 is still Enabled to ensure the display of the displayed content.

In some embodiments, the number and arrangement of pixels in each pixel group 1311 are the same. For example, each pixel group 1311 includes 4 pixels and is arranged in a 2*2 square.

Further, in some implementations, the number of pixels 1314 to be displayed in each pixel group 1311 is the same. That is to say, in S2, the same number of pixels are turned off in each of the same number of pixel groups 1311 , so that the brightness changes in each area of the display screen 130 are balanced, and the overall display effect looks comfortable.

Further, in some implementations, each pixel group 1311 has more than one pixel 1314 to be displayed, and S2 turns off the pixels 1314 to be displayed one by one.

That is to say, if the number of pixels 1314 to be displayed is greater than 1, the pixels 1314 to be displayed are turned off one by one in S2. For example, each pixel group 1311 includes 4 pixels, and the number of pixels 1314 to be displayed is 3, and the pixels to be displayed are turned off one by one for three times. In the first step, all pixel groups 1311 turn off one pixel 1314 to be displayed, and the remaining three pixels are lit; in the second step, each pixel group 1311 turns off one pixel 1314 to be displayed, and the remaining two pixels are lit; in the third step, each The pixel group 1311 turns off another pixel 1314 to be displayed, and the remaining pixel is turned on, and the brightness adjustment is completed so far.

Closing one by one can give the human eye a process of adaptation and buffering, avoiding discomfort to the human eye, and helping to protect the eye.

Please refer to FIG. 6 , further, in some implementations, each pixel 1314 to be displayed is turned off for the same duration.

When the pixels 1314 to be displayed are turned off one by one, the duration of turning off each pixel 1314 to be displayed is the same, or in other words, the time interval between each turn off is the same. In this way, the luminance change rate of the display screen 130, that is, the luminance decrease rate per unit time, is relatively stable, and will not decrease too much at once and then decrease too little suddenly, thereby avoiding discomfort to the human eye and helping to protect the eyes. .

In some implementations that are turned off successively, the duration of turning off each pixel 1314 to be displayed is a predetermined value. That is to say, the duration of turning off each to-be-displayed pixel 1314 is a preset fixed value. For example, each pixel group 1311 includes 4 pixels, and the duration of turning off each time is a preset 0.5 second. If there is only one pixel 1314 to be displayed, one turn off can be completed in an instant. If there are 2 pixels 1314 to be displayed, it needs to be turned off twice, a total of 0.5×(2-1)=0.5 seconds. If there are 3 pixels 1314 to be displayed, it needs to be turned off three times, a total of 0.5*(3-1)=1 second. The duration of each shutdown does not change due to the number of pixels 1314 to be displayed. In this way, no matter how many pixels are turned off, the rate of change of brightness is consistent, which can avoid discomfort caused by human eyes adapting to different rates of change of brightness.

In the above example, each pixel group 1311 includes only 4 pixels. If the pixel group 1311 includes more pixels, such as 9 or 12, and the number of pixels 1314 to be displayed is also more, maintaining a stable brightness change rate will It has more obvious beneficial effects and will be more helpful for eye protection.

Please refer to Fig. 7-9, in other implementation manners of successive closing, the control method includes:

S1a, determine the duration of turning off each pixel 1314 to be displayed according to the number of pixels 1314 to be displayed, the larger the number of pixels 1314 to be displayed, the shorter the duration of turning off each pixel 1314 to be displayed.

S1a can be realized by the duration determination module 111a of the control device 110 in some embodiments, the duration determination module 111a is used to determine the duration of closing each pixel 1314 to be displayed according to the number of pixels 1314 to be displayed, the larger the number of pixels 1314 to be displayed , the shorter the duration of turning off each pixel 1314 to be displayed is.

Please refer to FIG. 9 , that is to say, the duration of turning off each pixel 1314 to be displayed is not fixed, and is related to the number of pixels 1314 to be displayed. And the larger the number of pixels 1314 to be displayed is, the shorter the duration of turning off each pixel 1314 to be displayed is. For example, each pixel group 1311 includes 4 pixels. If the pixel 1314 to be displayed is 2, it needs to be closed twice, and the duration of each closing is set at 0.5s, that is, 0.5*(2-1)=0.5 seconds can be completed. If the pixel 1314 to be displayed is 3, it needs to be turned off three times, and the duration of each turn off can be set to 0.3s, a total of 0.3×2=0.6 seconds.

In this way, when there are too many pixels to be turned off, the time for turning off each pixel 1314 to be displayed is appropriately shortened, so that the total time of the adjustment process will not be too long, so as to realize fast adjustment. In some cases, for example, the ambient brightness changes suddenly, such as after the user turns off the lights in the room, quickly reducing the brightness of the display screen can help protect human eyes from being dazzled by the bright light of the display screen 130 .

Referring to Figures 10-11, in some embodiments, the control method includes:

S3. Determine the brightness of the target.

S3 may be implemented by the brightness determination module 113 of the control device 110 in some embodiments. That is, the brightness determination module 113 is used to determine the target brightness.

The adjustment parameters can only be determined after the target brightness is determined, that is, the brightness of the display screen to be adjusted.

There are many methods for determining the target brightness. For example, in some implementations, the control method determines the target brightness according to user input. For example, the user enters the brightness value, or slides the brightness adjustment bar to determine the target brightness, or the system enters a specific scene mode according to the user input, such as "highlight mode", and then automatically adjusts the display brightness according to the preset mode.

In some implementations, the above user input includes touch input or voice input. In some scenarios, it may be inconvenient for users to perform manual operations. Consider setting up the voice input function, which can provide users with convenience.

In some embodiments, the control method determines the target brightness according to the ambient brightness.

Please refer to FIG. 3 , in some implementations, the electronic device 100 includes a light sensor 150 , and ambient brightness is obtained through the light sensor 150 . The light sensor 150 is a device widely used in electronic devices 100 such as mobile phones, and can be used to sense ambient brightness. Generally, the light sensor 150 is disposed on the same side as the display screen 130 .

Please refer to FIG. 3 , in some implementations, the electronic device 100 includes an imaging device 170 , and the imaging device 170 is used to obtain an environment image, and the environment brightness is obtained by calculating the brightness value of the image.

The imaging device 170 may be a camera module disposed on the electronic device 100 , such as a device camera or a rear camera of a mobile phone.

The captured environmental image can be converted to HSL format to obtain the brightness value of each pixel, and then the brightness values of all pixels are added to obtain the average value, and the average value is used as the ambient brightness. The environmental image captured by the camera can cover a wider field of view, so a more objective environmental brightness can be obtained.

In addition, since a single image is taken, the brightness of the image may not be realistic and objective due to unexpected circumstances, such as fingers or other objects accidentally blocking the camera, or image distortion due to shaking. Therefore, multiple frames of images can be taken, and the average value of the average brightness values of each frame of images can be calculated as the average brightness. Further, screening can be performed in multiple frames of images, for example, eliminating images with too high or too low average brightness values (which may be caused by the above-mentioned accidents), and then using the remaining images to calculate the average brightness. In this way, more reasonable and objective results can be obtained.

Referring to Figures 12-13, in some implementations in which the target brightness is determined according to the ambient brightness, the control method includes:

S4, setting a relational expression between the ambient brightness and the target brightness; the target brightness is determined through the relational expression.

S4 may be implemented by the setting module 114 of the control device 110 in some embodiments. The setting module 114 is used to set the relational expression between the ambient brightness and the target brightness; the target brightness is determined by the relational expression.

Generally speaking, there should be a positive correlation between the target brightness and the ambient brightness, that is to say, the brighter the sensed ambient brightness is, the higher the target brightness should be, and the darker the ambient brightness, the darker the target brightness should be. In some implementations, the target brightness may be equal to the ambient brightness. Or, you can set the relationship between the ambient brightness and the target brightness, for example, the target brightness is the ambient brightness multiplied by a preset coefficient, or the target brightness is the ambient brightness plus a preset value, or there are more complicated relationships, etc. .

Through the setting of the relational expression, a more reasonable relationship between the target brightness and the ambient brightness can be obtained, so that a more suitable target brightness can be obtained according to the ambient brightness, so as to improve the user's physical fitness.

In some embodiments, the display screen 130 includes a self-illuminating display screen 130 .

In some implementations, the electronic device 100 includes an array of point light sources, and each point light source or every few point light sources form a pixel. By adjusting the brightness of the point light source is to adjust the brightness of the pixel, S2 can realize the adjustment of the overall brightness of the display screen 130 by turning off the point light source.

For example, in some embodiments, the display screen 130 may be an OLED display screen 130 . OLED (Organic Light-Emitting Diode) has the characteristic of self-luminescence, so the OLED display screen 130 can realize the technical solution of the above-mentioned point light source array. In addition, the OLED display screen 130 has the advantages of thin thickness, good vibration resistance, wide viewing angle, quick response, high luminous efficiency, and bendability.

By controlling the on or off of the point light source corresponding to the pixel, the control is more direct and the response is fast, thereby achieving the effect of eye protection.

The electronic device 100 in the embodiment of the present invention may include a display screen 130 and the control device 110 in the above embodiments. The control device 110 can be integrated into the electronic device 100 to enrich the functions of the electronic device 100 .
