[0030] The technical solution provided in the embodiments of the present application is described below with reference to the accompanying drawings.

[0031] It should be understood that in the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments, unless otherwise specified, "multiple" means two or more.

[0032] The method for adjusting screen brightness provided in the embodiment of the present application is applicable to electronic devices such as bicycle cycling computers, outdoor sports watches, wearable devices (such as smart watches), etc. This embodiment does not limit the specific type of electronic device.

[0033] Figure 1 is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application. Figure 1 As shown, the electronic device includes a display screen 110 , a background light source 120 , a plurality of solar panels 130 , and a screen brightness adjustment device 140 .

[0034] It is to be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the electronic device. In other embodiments, the electronic device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware. As an example, the electronic device is a bicycle cycling computer.

[0035] The display screen 110 is used to display the screen content of the electronic device. Generally, the screen content displayed by the display screen 110 is different according to the type of the electronic device. For example, the electronic device is a bicycle cycling computer. Figure 2 As shown, the screen content may include: the mileage of this ride, the duration of this ride, the cadence (i.e., pedaling frequency), the user's heart rate, and the date and time, etc., which are not specifically limited in this embodiment.

[0036] In the present embodiment, the display screen 110 is a reflective screen, that is, the display screen 110 itself does not emit light, but uses the mirror reflection principle to reflect the external light to illuminate the screen, thereby achieving the purpose of saving the operation of the electronic device. It can be understood that the screen brightness of the reflective screen is mainly determined by the ambient light. When the ambient light is sufficient, the display screen 110 has sufficient light to reflect and can clearly illuminate the screen. However, when the ambient light is weak or in a dark environment, the display screen 110 cannot display or cannot clearly display the screen content. Therefore, in order not to affect the effect of the user viewing the screen, the assistance of the background light source 120 is usually required to clearly display the screen content.

[0037] The background light source 120 is used to adjust the brightness of the display screen 110 so that the display screen 110 can clearly display the screen content. Specifically, the background light source 120 can emit light to compensate for the brightness of the display screen 110. Therefore, even in a weak ambient light or in a dark environment, the display screen 110 can clearly display the screen content.

[0038] A plurality of solar panels 130 are electrically connected to each other in series or in parallel to form a solar cell group to supply power to the background light source 120 so as to adjust the brightness of the display screen 110 .

[0039] The solar panel 130 is a device that uses solar energy as energy and converts solar energy into electrical energy. It has the advantages of being environmentally friendly, economical, and efficient, and is widely used in modern society. The solar panel 130 in an electronic device can improve the battery life of the electronic device, and can even help the electronic device achieve unlimited battery life without the need for additional charging.

[0040] It should be noted that, due to the large overall area of ​​the multiple solar panels 130, they are often partially shaded during use, and the shaded area is unstable. Therefore, the output parameters (such as output current and output voltage) of the multiple solar panels 130 as a whole are unstable. For a single solar panel 130, it is less likely to be partially shaded. In other words, its shade condition is relatively stable. Therefore, the output parameters of a single solar panel 130 are relatively stable and have good accuracy.

[0041] The screen brightness adjustment device 140 is used to adjust the light intensity of the background light source 120 , thereby adjusting the display brightness of the display screen 110 .

[0042] In some implementations, the screen brightness adjustment device 140 comprehensively adjusts the luminous intensity of the background light source according to the output parameters (such as output current or output voltage) of any solar panel 130 and the ambient light intensity of the electronic device, thereby adjusting the brightness of the display screen 110.

[0043] It is worth noting that in this embodiment, the electronic device determines the ambient light intensity of the electronic device based on the output parameters of a single solar panel, and then determines and adjusts the brightness of the display screen based on the ambient light intensity. Since there are fewer factors affecting the output parameters of a single solar panel, the output parameters are more accurate. Therefore, the ambient light intensity is more accurately determined based on the output parameters, which can improve the accuracy of the electronic device in adjusting the screen brightness, thereby improving the user experience.

[0044] In addition, compared with other electronic devices that measure the intensity of ambient light based on light sensors and adjust the brightness of the display screen according to the ambient light intensity, the electronic device provided in the embodiment of the present application does not need to add a light sensor to the stopwatch screen, has lower cost and power consumption, and avoids the requirements for process and layout when setting up the light sensor, making the manufacturing process more convenient.

[0045] Based on the electronic device provided in the above embodiment, the method for adjusting the screen brightness provided in the embodiment of the present application is described in detail below.

[0046] Figure 3 1 is a schematic flow chart of a method for adjusting screen brightness provided in an embodiment of the present application. The method is specifically controlled and executed by a screen brightness adjustment device 140 of an electronic device, and as Figure 3 As shown, the following steps S301 to S303 are included.

[0047] S301, detecting output parameters of a target solar panel, where the target solar panel is any one of a plurality of solar panels of an electronic device.

[0048] In this embodiment, the output parameter of the solar cell panel may be an output current or an output voltage, which is not limited in this embodiment. Based on the above description, it can be seen that the output current and output voltage are relatively stable and have good accuracy.

[0049] S302: Determine the ambient light intensity of the electronic device according to the output parameter.

[0050] Based on the output parameters including output voltage or output current, correspondingly, determining the ambient light intensity of the electronic device according to the output parameters includes: determining the ambient light intensity of the electronic device according to the output voltage or output current.

[0051] In this embodiment, the correspondence between the output parameter and the ambient light intensity is usually determined at the normal operating temperature of the solar panel (e.g., 10-30°C), and is applicable to a certain temperature range (e.g., 0-60°C), but is not applicable under some extreme temperature conditions (e.g., below 0°C or above 60°C). In other words, under extreme temperature conditions, the ambient light intensity determined according to the correspondence is significantly different from the actual ambient light intensity, and the result is inaccurate. Therefore, the electronic device can detect the operating temperature of the target solar panel and determine the ambient light intensity based on the operating temperature and the output parameter.

[0052] In some embodiments, when the operating temperature of the solar panel is within a preset temperature range, after determining the output parameter of a single solar panel, the electronic device can determine the ambient light intensity by searching the corresponding relationship between the output parameter and the ambient light intensity according to the output parameter. Exemplarily, the preset temperature range can be 0 to 60°C.

[0053] In other embodiments, when the operating temperature of the target solar panel is not within a preset temperature range, the electronic device corrects the corresponding relationship between the output parameter and the ambient light intensity according to the operating temperature; and determines the ambient light intensity according to the output parameter and the corrected corresponding relationship. Exemplarily, the preset temperature range may be 0 to 60°C.

[0054] For the convenience of description, in this embodiment, T is used to represent the operating temperature of the solar cell panel, and (T1, T2) is used to represent the above-mentioned preset temperature range.

[0055] Under the same ambient light intensity, compared to T in (T1, T2), when T<T1, the output parameters (such as output voltage or output current) of the solar panel will increase; and when T>T2, the output parameters of the solar panel will decrease. Therefore, in order to ensure the accuracy of the corresponding relationship between the output parameter and the ambient light intensity, when T<T1, the electronic device increases the output parameter in the corresponding relationship according to the preset rules; and when T>T2, the electronic device decreases the output parameter in the corresponding relationship according to the preset rules, thereby obtaining a corrected corresponding relationship.

[0056] This embodiment takes into account the influence of the operating temperature of the solar panel on the output parameters, and corrects the correspondence between the output parameters and the ambient light intensity within certain temperature ranges by means of temperature compensation. Therefore, the accuracy of the ambient light intensity measurement can be improved, and the precision and accuracy of the display screen brightness adjustment can be further improved.

[0057] S302, adjusting the luminous intensity of the background light source based on the ambient light intensity, thereby adjusting the brightness of the display screen.

[0058] In S302, the electronic device adjusts the luminous intensity of the background light source based on the ambient light intensity, including but not limited to the following method 1 or method 2.

[0059] Method 1: controlling the background light source 120 to be turned on and off based on the ambient light intensity.

[0060] In some embodiments, when the ambient light intensity is less than a preset intensity threshold, the background light source 120 is controlled to turn on to compensate for the ambient light intensity and illuminate the display screen 110. Also, when the ambient light intensity is greater than or equal to the intensity threshold, the background light source 120 is turned off to save power consumption of the electronic device and improve battery life.

[0061] Exemplarily, the intensity threshold may be 180 lux, 200 lux, etc., which is not limited in this embodiment.

[0062] Mode 2: when the background light source 120 is turned on, the light intensity of the background light source 120 is adjusted based on the ambient light intensity bar.

[0063] In some embodiments, the electronic device adjusts the luminous intensity of the background light source 120 according to the corresponding relationship between the ambient light intensity and the luminous intensity.

[0064] Specifically, the electronic device is preset with a correspondence between different ambient light intensity ranges and the luminous intensity of the background light source 120. Moreover, the larger the median value of the ambient light intensity range, the larger the corresponding luminous intensity. Exemplarily, the correspondence may be correspondence 1 shown in Table 1, or correspondence 2 shown in Table 2.

[0065] Table 1 Correspondence 1

[0066] Ambient light intensity / lux <![CDATA[Luminous intensity / (cd / m 2 )]]> 0-60 0-10 60-120 10-20 120-180 20-40

[0067] Table 2 Correspondence 2

[0068] Ambient light intensity / lux <![CDATA[Luminous intensity / (cd / m 2 )]]> 20-70 5-15 70-120 16-25 120-160 26-30

[0069] Based on this, after determining the ambient light intensity, the electronic device can look up the corresponding relationship shown in Table 1 or Table 2, determine the luminous intensity of the background light source corresponding to the ambient light intensity, and control the background light source to emit light according to the luminous intensity, thereby adjusting the brightness of the display screen.

[0070] For example, if the ambient light intensity is 80 lux and the electronic device is preset with the corresponding relationship 1 shown in Table 1, the electronic device can find out that the luminous intensity corresponding to 80 lux is 15 cd / m 2 , and control the background light source to emit 15cd / m 2 to brighten the display screen.

[0071] In addition, when the corresponding relationship 2 shown in Table 2 is preset in the electronic device, when the ambient light intensity is in a dark environment such as 0-20 lux, or in a bright environment such as an ambient light intensity greater than 160 lux, the electronic device can adjust the brightness of the background light source based on the user's control operation, so as to display the screen content at the brightness required by the user. Exemplarily, a knob, button, touch control or voice control module for controlling the brightness is provided on the electronic device, and the electronic device can control the specific adjustment of the brightness of the background light source according to the user's control operation of the knob, button or touch control, or according to the user's voice control operation, thereby adjusting the brightness of the display screen.

[0072] In other embodiments, the electronic device determines the luminous intensity of the background light source based on the target ambient light intensity. The target ambient light intensity is specifically the ambient light intensity after compensation by the background light source. The target ambient light intensity can be a fixed value, such as 180 lux, or can be specifically determined based on the current actual ambient light intensity.

[0073] For example, the electronic device is preset with different correspondences between ambient light intensities and target ambient light intensities, and the larger the median value of the intensity range of the current ambient light intensity, the larger the corresponding target ambient light intensity. The correspondence may be correspondence 3 shown in Table 3. Based on this, after determining the current actual ambient light intensity, the electronic device may search for correspondence 3 to determine the target ambient light intensity. Taking the current actual ambient light intensity of 60 lux as an example, searching for the correspondence shown in Table 3 may determine that the target ambient light intensity is 100 lux.

[0074] Table 3 Correspondence 3

[0075] Current ambient light intensity / lux Target ambient light intensity / lux 20-70 100 70-120 150 120-160 180

[0076] After determining the target luminous intensity, the electronic device needs to control the background light source to emit light to compensate for the ambient light, so that the compensated ambient light intensity of the electronic device reaches the target ambient light intensity.

[0077] In a possible implementation, after determining the target luminous intensity, the electronic device can determine the compensation step length according to the current ambient light intensity, the target ambient light intensity and the adjustment duration, and compensate the ambient light intensity of the electronic device to the target ambient light intensity according to the compensation step length, thereby gradually brightening the brightness of the display screen. The compensation step length is used to represent the change in the actual ambient light intensity per unit time.

[0078] For example, if the current ambient light intensity of the electronic device is 60 lux, the target ambient light intensity is 100 lux, and the adjustment time is 2 seconds, the electronic device can determine the compensation step length as (100 lux - 60 lux) / 2s = 20 lux / s. Subsequently, the electronic device controls the background light source to compensate the ambient light intensity of the display screen at a speed of 20 lux / s, thereby illuminating the display screen so that the user can clearly see the screen content.

[0079] In this embodiment, the electronic device realizes automatic adjustment of the background light source and brightness by processing and controlling the output parameters, ambient light intensity, luminous intensity and other data. This method not only ensures that the user can clearly see the screen in different environments, but also realizes accurate adjustment of the brightness of the meter screen, which has a high user experience.
