Description

Technical Field

[0001] This invention relates to the field of automatic dimming technology, specifically to a backlight adjustment method, a backlight adjustment device, and an electronic device. Background Technology

[0002] Most electronic devices automatically adjust their backlight brightness based on ambient light. These devices typically have only one or two illuminance sensors. Furthermore, these sensors are usually located in front of or behind the display, and can only detect ambient light along the sides of the display's thickness. When strong light is present in front of or behind the display, they cannot detect the true ambient light intensity. Summary of the Invention

[0003] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0004] The viewing angle of a single illuminance sensor is typically less than 120 degrees. When an electronic device's display has only one illuminance sensor, the ambient light intensity detected within the viewing angle of that single sensor is used as the ambient light illuminance. When the ambient light source is outside the viewing range of the single illuminance sensor, the illuminance value detected by the sensor is relatively low. Consequently, the backlight value of the display screen obtained by mapping the light-sensing value is relatively low, resulting in a poor user experience.

[0005] When an electronic device's display has two illuminance sensors, one located in front of the display and the other in the rear, the maximum value from both sensors is typically taken as the ambient light illuminance value. However, when a strong light source approaches from the front or rear of the display, a relatively large ambient light illuminance value is obtained, which does not match the actual illuminance value of the environment. Consequently, the backlight value of the display screen obtained through the mapping of the light sensor value is relatively high, resulting in a poor user experience.

[0006] The present invention aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, embodiments of the present invention propose a backlight adjustment method that can adjust the backlight brightness of the display screen according to the illuminance value of the real ambient light, thereby obtaining the most suitable backlight brightness value.

[0008] An embodiment of the present invention provides a backlight adjustment device that uses three illuminance sensors to reproduce the illuminance value of real ambient light, thereby adjusting the most suitable backlight brightness value.

[0009] Embodiments of the present invention provide an electronic device that can use three illuminance sensors to reproduce the illuminance value of real ambient light, thereby adjusting the display screen to the most suitable backlight brightness value.

[0010] An embodiment of the present invention provides an electronic device capable of implementing the aforementioned backlight adjustment method.

[0011] The backlight adjustment method according to an embodiment of the present invention includes the following steps:

[0012] Detect and acquire the first illuminance value of ambient light on one side of the display screen in the thickness direction;

[0013] Detect and acquire the second illuminance value of the ambient light on the other side of the thickness direction of the display screen;

[0014] The third illuminance value of the ambient light on one side of the display screen in the length or width direction is detected and obtained, wherein the absolute value of the difference between the first illuminance value and the second illuminance value is the first difference value, the absolute value of the difference between the first illuminance value and the third illuminance value is the second difference value, and the absolute value of the difference between the second illuminance value and the third illuminance value is the third difference value.

[0015] The first illuminance value, the second illuminance value, and the third illuminance value shall be taken as the illuminance value of ambient light based on at least one of the first difference, the second difference, and the third difference.

[0016] The backlight brightness of the display screen is adjusted based on the ambient light illuminance value.

[0017] According to the backlight adjustment method of the present invention, the illuminance values ​​of ambient light in multiple directions of the display screen are detected and obtained, thereby improving the detection range and enabling the acquisition of the true ambient light illuminance values.

[0018] Therefore, the backlight adjustment method of this invention can adjust the backlight brightness of the display screen according to the illuminance value of the real ambient light, thereby obtaining the most suitable backlight brightness value.

[0019] In some embodiments, the third illuminance value is taken as the illuminance value of ambient light based on at least one of the first difference, the second difference, and the third difference, or the largest of the first illuminance value, the second illuminance value, and the third illuminance value is taken as the illuminance value of ambient light.

[0020] In some embodiments, when the display screen is turned on, if the first difference is greater than or equal to the first preset value, the third illuminance value is used as the illuminance value of the ambient light.

[0021] In some embodiments, after the step of taking the third illuminance value as the illuminance value of ambient light if the first difference is greater than or equal to a first preset value, the following steps are included:

[0022] If the first difference is greater than or equal to the first preset value, the third illuminance value is retained as the illuminance value of the ambient light.

[0023] If each of the first difference, the second difference, and the third difference is less than or equal to a second preset value, wherein the first preset value is greater than the second preset value, the largest of the first illuminance value, the second illuminance value, and the third illuminance value shall be taken as the illuminance value of the ambient light.

[0024] If the first difference is less than the first preset value, and at least one of the first difference, the second difference, and the third difference is greater than the second preset value, the third illuminance value is maintained as the illuminance value of the ambient light.

[0025] In some embodiments, when the display screen is turned on, if the first difference is less than a first preset value, the largest of the first illuminance value, the second illuminance value, and the third illuminance value is taken as the illuminance value of the ambient light.

[0026] In some embodiments, after the step of taking the largest of the first illuminance value, the second illuminance value, and the third illuminance value as the illuminance value of ambient light if the first difference is less than a first preset value, the following steps are included:

[0027] If each of the first difference, the second difference, and the third difference is less than or equal to a second preset value, wherein the first preset value is greater than the second preset value, the largest of the first illuminance value, the second illuminance value, and the third illuminance value is kept as the illuminance value of the ambient light.

[0028] If the first difference is greater than or equal to the first preset value, the third illuminance value is taken as the illuminance value of the ambient light.

[0029] If the first difference is less than the first preset value, and at least one of the first difference, the second difference, and the third difference is greater than the second preset value, the largest of the first illuminance value, the second illuminance value, and the third illuminance value is kept as the illuminance value of the ambient light.

[0030] A backlight adjustment device according to an embodiment of the present invention includes:

[0031] The first illuminance sensor is used to detect the first illuminance value of ambient light on one side of the display screen in the thickness direction;

[0032] The second illuminance sensor is used to detect the second illuminance value of the ambient light on the other side of the thickness direction of the display screen;

[0033] The third illuminance sensor is used to detect the third illuminance value of the ambient light on one side of the display screen in the length or width direction.

[0034] The acquisition module is used to acquire the first illuminance value, the second illuminance value, and the third illuminance value;

[0036] According to the backlight adjustment device of the present invention, three illuminance sensors are used to detect the illuminance value of ambient light from different directions, thereby increasing the viewing angle of the illuminance sensors and improving the detection range, so as to obtain the illuminance value of real ambient light.

[0037] Therefore, the backlight adjustment device of this embodiment of the invention uses three illuminance sensors to reproduce the illuminance value of the real ambient light, thereby adjusting to the most suitable backlight brightness value.

[0043] The third illuminance sensor is used to detect the third illuminance value of the ambient light on one side of the display screen in the length or width direction.

[0046] According to the electronic device of the present invention, three illuminance sensors are used to detect the illuminance value of ambient light from different positions of the display screen, thereby increasing the viewing angle of the illuminance sensors and improving the detection range, so as to obtain the illuminance value of the real ambient light.

[0062] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0063] The backlight adjustment method of the present invention is described below with reference to the accompanying drawings.

[0064] like Figure 1 As shown, the backlight adjustment method according to an embodiment of the present invention includes the following steps:

[0065] S101. Detect and obtain the first illuminance value.

[0066] Specifically, the first illuminance value of the ambient light on one side (in front of the display screen) in the thickness direction of the display screen is detected by the first illuminance sensor.

[0067] S102. Detect and obtain the second illuminance value.

[0068] Specifically, a second illuminance value of the ambient light on the other side (behind the display screen) in the thickness direction of the display screen is detected and obtained using a second illuminance sensor.

[0069] S103. Detect and obtain the third illuminance value.

[0070] Specifically, a third illuminance sensor is used to detect and acquire the third illuminance value of the ambient light on one side (above, below, left, or right of the display screen) in the length or width direction. Preferably, the third illuminance sensor detects and acquires the third illuminance value of the ambient light above the display screen.

[0071] It should be noted that the absolute value of the difference between the first illuminance value and the second illuminance value is the first difference, the absolute value of the difference between the first illuminance value and the third illuminance value is the second difference, and the absolute value of the difference between the second illuminance value and the third illuminance value is the third difference.

[0072] S104. Based on at least one of the first difference, the second difference, and the third difference, one of the first illuminance value, the second illuminance value, and the third illuminance value shall be taken as the illuminance value of the ambient light.

[0073] Specifically, based on the first difference, or the second difference, or the third difference, or the first difference and the second difference, or the first difference and the third difference, or the second difference and the third difference, or the first difference, the second difference and the third difference, or the first difference, the second difference and the third difference, the one that can reproduce the real ambient light among the first illuminance value, the second illuminance value and the third illuminance value shall be taken as the illuminance value of the ambient light.

[0074] S105. Adjust the backlight brightness of the display screen based on the ambient light illuminance value.

[0075] According to the backlight adjustment method of the present invention, the illuminance values ​​of ambient light in multiple directions of the display screen are detected and obtained, thereby improving the detection range and enabling the acquisition of the true ambient light illuminance values.

[0076] Therefore, the backlight adjustment method of this invention can adjust the backlight brightness of the display screen according to the illuminance value of the real ambient light, thereby obtaining the most suitable backlight brightness value.

[0077] It is understandable that S101, S102, and S103 have no specific order.

[0078] As one possible implementation, the third illuminance value can be used as the illuminance value of the ambient light, or the largest of the first, second, and third illuminance values ​​can be used as the illuminance value of the ambient light.

[0079] In other words, such as Figure 2 As shown, the backlight adjustment method of this invention includes the following steps:

[0080] S201. Detect and obtain the first illuminance value.

[0081] S202. Detect and obtain the second illuminance value.

[0082] S203. Detect and obtain the third illuminance value.

[0083] S204. The third illuminance value is taken as the illuminance value of the ambient light based on at least one of the first difference, the second difference, and the third difference, or the largest of the first illuminance value, the second illuminance value, and the third illuminance value is taken as the illuminance value of the ambient light.

[0084] When the monitor is operating, if the first difference is greater than or equal to the first preset value, the third illuminance value is used as the ambient light illuminance value. In this case, the illuminance of the ambient light in front of and behind the monitor differs significantly, indicating that a strong light source is approaching from the front or back of the monitor. The accuracy of the first and second illuminance values ​​decreases, while the accuracy of the third illuminance value remains unaffected. Therefore, the third illuminance value is used as the ambient light illuminance value.

[0085] When the monitor is operating, if any of the first, second, and third differences is less than or equal to a second preset value, where the first preset value is greater than the second preset value, the largest of the first, second, and third illuminance values ​​is taken as the illuminance value of the ambient light. In this case, the ambient light is not disturbed, and the largest of the first, second, and third illuminance values ​​can reproduce the true ambient light. Therefore, the largest of the first, second, and third illuminance values ​​is taken as the illuminance value of the ambient light.

[0086] Understandably, the first preset value is 800-1200 lux, and the second preset value is 100-300 lux. Specifically, the first preset value can be 1000 lux, and the second preset value can be 200 lux. Of course, provided that the first preset value is greater than the second preset value, the first and second preset values ​​can also be set according to the actual situation.

[0087] S205. Adjust the backlight brightness of the display screen based on the ambient light illuminance value.

[0088] like Figure 3 As shown, in some embodiments, when the display screen is turned on, if the first difference is greater than or equal to the first preset value, the third illuminance value is used as the illuminance value of the ambient light.

[0089] At this point, the significant difference in illuminance between the ambient light in front of and behind the monitor indicates the presence of a strong light source. This reduces the accuracy of the first and second illuminance values, while the accuracy of the third illuminance value remains unaffected. Therefore, the third illuminance value is taken as the ambient light illuminance value.

[0090] After using the third illuminance value as the illuminance value of the ambient light, if the first difference is greater than or equal to the first preset value, the third illuminance value is kept as the illuminance value of the ambient light.

[0091] At this time, the interference from strong light sources in front of or behind the monitor has not ended, and the third illuminance value is still used as the illuminance value of the ambient light.

[0092] After taking the third illuminance value as the illuminance value of the ambient light, if each of the first difference, the second difference, and the third difference is less than or equal to the second preset value, where the first preset value is greater than the second preset value, then the largest of the first illuminance value, the second illuminance value, and the third illuminance value is taken as the illuminance value of the ambient light.

[0093] At this point, the strong light source in front of or behind the monitor disappears, and the ambient light is not disturbed. The largest of the first, second, and third illuminance values ​​can reproduce the true ambient light. Therefore, the largest of the first, second, and third illuminance values ​​is taken as the illuminance value of the ambient light.

[0094] After using the third illuminance value as the illuminance value of the ambient light, if the first difference is less than the first preset value, and at least one of the first difference, the second difference, and the third difference is greater than the second preset value, the third illuminance value is maintained as the illuminance value of the ambient light.

[0095] At this point, the influence of strong light sources in front of or behind the monitor is reduced, but the ambient light is still affected, and the condition of using the largest of the first, second, and third illuminance values ​​as the ambient light illuminance value is not met. Therefore, the third illuminance value is still used as the ambient light illuminance value.

[0096] like Figure 3 As shown, in some embodiments, when the display screen is turned on, if the first difference is less than the first preset value, the largest of the first illuminance value, the second illuminance value, and the third illuminance value is taken as the illuminance value of the ambient light.

[0097] In this case, the ambient light is undisturbed, and the largest of the first, second, and third illuminance values ​​can reproduce the true ambient light. Therefore, the largest of the first, second, and third illuminance values ​​is taken as the illuminance value of the ambient light.

[0098] After taking the largest of the first, second, and third illuminance values ​​as the illuminance value of the ambient light, if each of the first, second, and third differences is less than or equal to a second preset value, wherein the first preset value is greater than the second preset value, the largest of the first, second, and third illuminance values ​​is kept as the illuminance value of the ambient light.

[0099] In this case, since the ambient light has not been disturbed, the largest of the first, second, and third illuminance values ​​is still taken as the ambient light illuminance value.

[0100] After taking the largest of the first, second, and third illuminance values ​​as the illuminance value of the ambient light, if the first difference is greater than or equal to the first preset value, the third illuminance value is taken as the illuminance value of the ambient light.

[0101] In this situation, the significant difference in illuminance between the ambient light in front of and behind the monitor indicates the presence of a strong light source. This reduces the accuracy of the first and second illuminance values, while the accuracy of the third illuminance value remains unaffected. Therefore, the third illuminance value is used as the ambient light illuminance value.

[0102] After taking the largest of the first, second, and third illuminance values ​​as the illuminance value of the ambient light, if the first difference is less than the first preset value, and at least one of the first, second, and third differences is greater than the second preset value, the third illuminance value is kept as the illuminance value of the ambient light.

[0103] In this situation, the ambient light is somewhat disturbed, but there is no strong light source in front of or behind the monitor. Therefore, the accuracy of the first and second illuminance values ​​is minimally affected. The largest of the first, second, and third illuminance values ​​can still reproduce the true ambient light, and the conditions for using the third illuminance value as the ambient light illuminance value are not met. Therefore, the largest of the first, second, and third illuminance values ​​is still used as the ambient light illuminance value.

[0104] It is understood that the first difference being less than the first preset value includes: the first difference being less than the first preset value, and at least one of the first difference, the second difference, and the third difference being greater than the second preset value; and each of the first difference, the second difference, and the third difference being less than or equal to the second preset value.

[0105] When the display screen is turned on, if the first difference is less than the first preset value, and at least one of the first difference, the second difference, and the third difference is greater than the second preset value, then the largest of the first illuminance value, the second illuminance value, and the third illuminance value is taken as the illuminance value of the ambient light.

[0106] After the display screen is turned on, and the largest of the first, second, and third illuminance values ​​has been determined as the ambient light illuminance value or the third illuminance value has been determined as the ambient light illuminance value, if the first difference is less than the first preset value, and at least one of the first, second, and third differences is greater than the second preset value, then the largest of the determined first, second, and third illuminance values ​​will be kept as the ambient light illuminance value or the third illuminance value has been determined as the ambient light illuminance value.

[0107] For ease of understanding, please refer to the following: Figure 3 The backlight adjustment method of the present invention, in conjunction with the above content, will be specifically described below, including the following steps:

[0108] S301. Detect and obtain the first illuminance value.

[0109] S302. Detect and obtain the second illuminance value.

[0110] S303, Detect and obtain the third illuminance value.

[0111] S304. When the display is turned on, identify the magnitudes of the first difference, the second difference, and the third difference.

[0112] Specifically, if condition A is met, steps S401 and S402 are executed. If condition A is not met, steps S501 and S502 are executed.

[0113] S401. Use the third illuminance value as the illuminance value of the ambient light.

[0114] S402, Continue to identify the magnitudes of the first, second, and third differences.

[0115] Specifically, if condition A is met, then steps S401 and S402 are executed. If condition B is met, then steps S501 and S502 are executed. If condition C is met, then steps S401 and S402 are executed.

[0116] S501, the largest of the first illuminance value, the second illuminance value, and the third illuminance value shall be taken as the illuminance value of the ambient light.

[0117] S502, Continue to identify the magnitudes of the first, second, and third differences.

[0118] Specifically, if condition A is met, steps S401 and S402 are executed. If condition B is met, steps S501 and S502 are executed. If condition C is met, steps S501 and S502 are executed.

[0119] Understandably, condition A is: the first difference is greater than or equal to the first preset value. Condition B is: each of the first, second, and third differences is less than or equal to the second preset value. Condition C is: the first difference is less than the first preset value, and at least one of the first, second, and third differences is greater than the second preset value.

[0120] The backlight adjustment device according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0121] like Figure 4 As shown, the backlight adjustment device according to an embodiment of the present invention includes a first illuminance sensor 701, a second illuminance sensor 702, a third illuminance sensor 703, an acquisition module 704, and a control module 705.

[0122] The first illuminance sensor 701 is used to detect the first illuminance value of ambient light on one side (in front of the display screen) in the thickness direction of the display screen. The second illuminance sensor 702 is used to detect the second illuminance value of ambient light on the other side (behind the display screen) in the thickness direction of the display screen. The third illuminance sensor 703 is used to detect the third illuminance value of ambient light on one side (above, below, left, or right of the display screen) in the length or width direction of the display screen.

[0123] It is understood that the display includes a screen, which is located on the front side of the monitor, and the front side of the screen is the side where the screen interface can be seen. The first illuminance sensor can be located on the back side of the screen, that is, on the side of the monitor connected to the screen, or it can be located in other positions that can detect the ambient light in front of the screen. The second illuminance sensor can be located behind the monitor, or in other positions that can detect the ambient light behind the screen. The third illuminance sensor can be located on or above the screen, or in other positions that can detect the ambient light above the screen. Of course, the first, second, and third illuminance sensors can also be specifically set according to the actual situation.

[0124] The acquisition module 704 is used to acquire the first illuminance value, the second illuminance value, and the third illuminance value.

[0125] The control module 705 is used to take one of the first illuminance value, the second illuminance value and the third illuminance value as the illuminance value of the ambient light. The control module 705 is also used to adjust the backlight brightness of the display screen based on the illuminance value of the ambient light.

[0126] Specifically, the control module 705 uses one of the first illuminance value, the second illuminance value, and the third illuminance value as the illuminance value of the ambient light according to the backlight adjustment method of any of the above embodiments.

[0127] According to the backlight adjustment device of the present invention, three illuminance sensors are used to detect the illuminance value of ambient light from different directions, thereby increasing the viewing angle of the illuminance sensors and improving the detection range, so as to obtain the illuminance value of real ambient light.

[0128] Therefore, the backlight adjustment device of this embodiment of the invention uses three illuminance sensors to reproduce the illuminance value of the real ambient light, thereby adjusting to the most suitable backlight brightness value.

[0129] The electronic device according to embodiments of the present invention will now be described with reference to the accompanying drawings.

[0130] like Figure 5 As shown, an electronic device according to an embodiment of the present invention includes a display 800 and a backlight adjustment device. The display 800 includes a display screen, which is disposed on the front side of the display 800. The backlight adjustment device includes a first illuminance sensor 701, a second illuminance sensor 702, a third illuminance sensor 703, an acquisition module 704, and a control module 705.

[0131] The first illuminance sensor 701 is used to detect one side of the display screen in the thickness direction (e.g., Figure 5 The first illuminance value of the ambient light (in front of the central display screen). The second illuminance sensor 702 is used to detect the other side (e.g., in the thickness direction of the display screen) of the central display screen. Figure 5 The second illuminance value is the ambient light behind the central display screen. The third illuminance sensor 703 is used to detect the ambient light on one side (e.g., behind the central display screen) in the length or width direction. Figure 5 The third illuminance value of ambient light (above, below, to the left, or to the right of the central display screen).

[0132] It's understandable that the front of the display screen is the side where the screen interface is visible. The first illuminance sensor can be located on the back of the display screen, that is, on the side of the display connected to the screen, or it can be located in any other position that can detect ambient light in front of the screen. The second illuminance sensor can be located behind the display screen, or in any other position that can detect ambient light behind the display screen. The third illuminance sensor can be located on or above the display screen, or in any other position that can detect ambient light above the display screen. Of course, the first, second, and third illuminance sensors can be configured according to the specific circumstances.

[0133] The acquisition module 704 is used to acquire the first illuminance value, the second illuminance value, and the third illuminance value.

[0134] The control module 705 is used to take one of the first illuminance value, the second illuminance value and the third illuminance value as the illuminance value of the ambient light. The control module 705 is also used to adjust the backlight brightness of the display screen based on the illuminance value of the ambient light.

[0135] Specifically, the control module 705 uses one of the first illuminance value, the second illuminance value, and the third illuminance value as the illuminance value of the ambient light according to the backlight adjustment method of any of the above embodiments.

[0136] According to the electronic device of the present invention, three illuminance sensors are used to detect the illuminance value of ambient light from different positions of the display screen, thereby increasing the viewing angle of the illuminance sensors and improving the detection range, so as to obtain the illuminance value of the real ambient light.
