DETAILED DESCRIPTION

[0020] Exemplary embodiments of the disclosure are described in further detail with reference to the drawings below. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for a more thorough understanding of the present disclosure, and to convey the scope of the present disclosure to those skilled in the art completely.

[0021] FIG. 1 illustrates a schematic flow diagram of a method for adjusting the display brightness of a screen according to an embodiment of the present invention. As shown in FIG. 1, the method includes steps as follows.

[0022] Step S100: a light brightness condition of the screen within a visible range is detected.

[0023] Specifically the light brightness condition of the screen within the visible range is related to the environment in which the user is using the screen. For example, the screen may be a screen of a fixed apparatus such as television, desktop computer, and also may be a screen of a mobile apparatus such as mobile phone, PAD or laptop computer. However, the light brightness condition of the screen within the visible range may be mainly related to the intensity of light emitted by the sun and light intensity of an illumination apparatus around the screen. It is assumed that a visible range of a screen may be a range of a few meters in front of the screen when the screen is a screen of a television.

[0024] Specifically, in the step S100, it is possible to detect the light brightness condition of the screen within the visible range at a preset time interval to obtain a light brightness value of the screen within the visible range. Specifically, the preset time interval may be a time interval such as 30 minutes, 1 hour, or 2 hours. Those skilled in the art may make specific settings for the preset time interval according to the actual needs. In order to meet different needs of individual users, the users may also customize settings of the preset time interval.

[0025] For example, when the preset time interval is 2 hours, in the step S100, the light brightness condition of the screen within the visible range is detected every 2 hours to obtain a light brightness value of the screen within the visible range.

[0026] Step S101: the display brightness of the screen is adjusted according to the detected light brightness condition of the screen within the visible range.

[0027] After the light brightness condition of the screen within the visible range is detected in the step S100, it is possible to adjust the display brightness of the screen according to the detected light brightness condition of the screen within the visible range in the step S101.

[0028] Specifically, the light brightness condition of the screen within the visible range may be detected in the step S100, and then in the step S101, the display brightness of the screen may be adjusted according to the detected light brightness value of the screen within the visible range in the step S100 and a preset light brightness threshold. Those skilled in the art may make specific settings for the preset light brightness threshold according to the actual needs. For example, the preset light brightness threshold may include a first light brightness threshold value, a second light brightness threshold and a third light brightness threshold.

[0029] When the preset light brightness threshold includes a first light brightness threshold, a second light brightness threshold and a third light brightness threshold, and the first light brightness threshold is less than the second light brightness threshold and the second light brightness threshold is less than the third light brightness threshold, the step S101 may include: adjusting the display brightness of the screen to make the screen displaying at a first brightness, when the detected light brightness value of the screen within the visible range is less than the first light brightness threshold; adjusting the display brightness of the screen to make the screen displaying at a second brightness, when the detected light brightness value of the screen within the visible range is more than or equal to the first light brightness threshold and less than the second light brightness threshold; adjusting the display brightness of the screen to make the screen displaying at a third brightness, when the detected light brightness value of the screen within the visible range is more than or equal to the second light brightness threshold and less than the third light brightness threshold; and adjusting the display brightness of the screen to make the screen displaying at a fourth brightness, when the detected light brightness value of the screen within the visible range is more than or equal to the third light brightness threshold. Specifically, the first brightness is less than the second brightness, the second brightness is less than the third brightness, and the third brightness is less than the fourth brightness.

[0030] In addition, by applying the technology solutions according to the present invention, the steps of detecting the light brightness condition of the screen within the visible range and adjusting the display brightness of the screen according to the detected light brightness condition of the screen within the visible range may be rapidly completed, thus achieving a technical effect of adjusting rapidly and automatically the display brightness of the screen. For example, by applying the technology solutions according to the present invention, the steps of detecting the light brightness condition of the screen within the visible range and adjusting the display brightness of the screen may be completed within 1-2 seconds and even less.

[0031] For example, the technical solutions according to the embodiments of the present invention may be applied to televisions. Generally, indoor lighting is adequate at noon and in the afternoon, that is, the light brightness value of the screen of the television within the visible range is higher. In this case, by applying the technical solutions according to the present invention, the display brightness of the screen may be adjusted rapidly and automatically to make the screen displaying with the higher display brightness; while indoor lighting is inadequate in the late afternoon and in the evening, that is, the light brightness value of the screen of the television within the visible range is lower. In this case, by applying the technical solutions according to the present invention, the display brightness of the screen may be adjusted rapidly and automatically to make the screen displaying with the lower display brightness.

[0032] For example, the technical solutions according to the embodiments of the present invention may be applied to mobile phones. There are many people like to browse news, stories, videos or play games for a while by means of a mobile phone after the lights are turned off and before going to sleep. At this time, if the screen of the mobile phone has been displaying with the higher display brightness, it will bring a bad feeling of dazzling to the user, and watching the screen with the higher display brightness in a darker environment for a long time may also cause damage to the user's eyes. In this case, by applying the technical solutions according to the embodiment of the present invention, the display brightness of the screen may be adjusted conveniently, rapidly and automatically, reducing the damage for the user's eye.

[0033] With the method for adjusting the light brightness of the screen according to the present embodiment, a light brightness condition of the screen within a visible range is detected, and the display brightness of the screen is adjusted according to the detected light brightness condition of the screen within the visible range. With the technical solutions according to the present invention, the display brightness of the screen can be adjusted conveniently, intelligently automatically and rapidly, the method for adjusting the display brightness of the screen is optimized, and there is provided a protection for the user's eye, improving the sense of the experience of the user.

[0034] FIG. 2 illustrates a schematic functional structure diagram of a device for adjusting the display brightness of a screen according to an embodiment of the present invention. As shown in FIG. 2, the device includes a detection module 210 and an adjustment module 220.

[0035] The detection module 210 is adapted to detect a light brightness condition of the screen within a visible range.

[0036] Specifically the light brightness condition of the screen within the visible range is related to the environment in which the user is using the screen. For example, the screen may be a screen of a fixed apparatus such as television, desktop computer, and also may be a screen of a mobile apparatus such as mobile phone, PAD or laptop computer. However, the light brightness condition of the screen within the visible range may be mainly related to the intensity of light emitted by the sun and light intensity of an illumination apparatus around the screen.

[0037] The detection module 210 is further adapted to detect the light brightness condition of the screen within the visible range at a preset time interval to obtain a light brightness value of the screen within the visible range.

[0038] Specifically, the preset time interval may be a time interval such as 30 minutes, 1 hour, or 2 hours. Those skilled in the art may make specific settings for the preset time interval according to the actual needs. In order to meet different needs of individual users, the user may also customize settings of the preset time interval. It is assumed that the preset time interval is 30 minutes, and the light brightness condition of the screen within the visible range is detected every 30 minutes to obtain a light brightness value of the screen within the visible range.

[0039] The adjustment module 220 is adapted to adjust display brightness of the screen according to the detected light brightness condition of the screen within the visible range.

[0040] After the light brightness condition of the screen within the visible range is detected by the detection module 210, the adjustment module 220 is triggered to adjust the display brightness of the screen according to the detected light brightness condition of the screen within the visible range.

[0041] Specifically, the light brightness condition of the screen within the visible range may be detected by the detection module 210, and then, the display brightness of the screen may be adjusted by the adjustment module 220 according to the detected light brightness value of the screen within the visible range and a preset light brightness threshold. Those skilled in the art may make specific settings for the preset light brightness threshold according to the actual needs.

[0042] For example, when the preset light brightness threshold includes a first light brightness threshold, a second light brightness threshold and a third light brightness threshold, and the first light brightness threshold is less than the second light brightness threshold and the second light brightness threshold is less than the third light brightness threshold, the adjustment module 220 is further adapted to adjust the display brightness of the screen to make the screen displaying at a first brightness, when the detected light brightness value of the screen within the visible range is less than the first light brightness threshold; adjusting the display brightness of the screen to make the screen displaying at a second brightness, when the detected light brightness value of the screen within the visible range is more than or equal to the first light brightness threshold and less than the second light brightness threshold; adjusting the display brightness of the screen to make the screen displaying at a third brightness, when the detected light brightness value of the screen within the visible range is more than or equal to the second light brightness threshold and less than the third light brightness threshold; and adjusting the display brightness of the screen to make the screen displaying at a fourth brightness, when the detected light brightness value of the screen within the visible range is more than or equal to the third light brightness threshold. Specifically, the first brightness is less than the second brightness, the second brightness is less than the third brightness, and the third brightness is less than the fourth brightness.

[0043] With the device for adjusting the light brightness of the screen according to the present embodiment, a light brightness condition of the screen within a visible range is detected by the detection module, and the display brightness of the screen is adjusted by the adjustment module according to the detected light brightness condition of the screen within the visible range. With the technical solutions according to the present invention, the display brightness of the screen can be adjusted conveniently, intelligently automatically and rapidly, the method for adjusting the display brightness of the screen is optimized, and there is provided a protection for the user's eye, improving the sense of the experience of the user.

[0044] Embodiments of the present invention also provide an electronic device, which includes the above-described device for adjusting the brightness of a screen. Specifically, the electronic apparatus may be a television, a desktop computer, a mobile phone, a PAD or a laptop computer and other electronic device which have a screen.

[0045] For example, when the electronic device is a television, in particular, a light-sensitive sensor may be used as a detection module in a device with the brightness of the screen to be adjusted, and the detection module and the adjustment module may be integrated anywhere in the television. However, in order to facilitate the layout of hardware and structure, preferably, the detection module 310 may be provided on the bottom of the television 300 (the position shown at a circle in FIG. 3), for example the detection module 310 is integrated on the same hardware with an infrared circuits and so on, and the adjustment module (not shown in drawings) is provided inside the television 300, as shown in FIG. 3.

[0046] Further, an embodiment of the present invention further provides a non-transitory computer-readable storage medium storing executable instructions, which can be executed by an electronic device to perform any methods for adjusting the display brightness of a screen mentioned by embodiments of the present invention.

[0050] Processor 410, memory 420, input unit 430 and output unit 440 can be connected by BUS or other methods, and BUS connecting is showed in FIG. 4 for an example.

[0051] Memory 420 can be used for storing non-transitory software program, non-transitory computer executable program and modules as a non-transitory computer-readable storage medium, such as corresponding program instructions/modules for the methods for adjusting the display brightness of a screen mentioned by embodiments of the present invention (such as shown in FIG. 2, detecting module 210 and adjusting module 220). Processor 410 performs kinds of functions and data processing of the electronic device by executing non-transitory software program, instructions and modules which are stored in memory 420, thereby realizes the methods for adjusting the display brightness of a screen mentioned by embodiments of the present invention.
