[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Display devices are widely used in various scenarios. Different scenarios have different requirements for brightness. The brightness of display devices is difficult to meet the brightness requirements of bright scenes. In related technologies, technologies to increase brightness are usually accompanied by increased power consumption, and it is difficult to increase brightness while controlling power consumption. For example, when a Mini LED direct display product with a dot pitch of 0.9 displays a pure white screen at a brightness of 500nit, the power consumption of a 4K display system is about 2880W. If the brightness is increased to 1000nit, the power consumption of the 4K display system increases to about 6000W, doubling the power consumption.

[0026] See also Figure 1 The embodiment of the present invention provides a power balancing method, the power balancing method comprising:

[0027] 01: Determine the reference current and preset reference value.

[0028] 02: Determine the sum of the brightness values ​​of all pixels corresponding to the image to be displayed as a data statistical value.

[0029] 03: Determine the quotient of the preset reference value and the data statistical value as a balance coefficient, and the balance coefficient is greater than or equal to 1.

[0030] 04: Determine the product of the reference current and the balance coefficient as the actual current, and the actual current is greater than or equal to the reference current.

[0031] 05: Control the display module 10 to display the image to be displayed with the actual current.

[0032] Specifically, see Figure 2 The power balancing method of this embodiment can be implemented by the display device 100 of the embodiment of the present invention. The display device 100 includes a display module 10. The display device 100 also includes a first determination module 20, a second determination module 30, a third determination module 40, a fourth determination module 50 and a control module 60. Among them, step 01 can be implemented by the first determination module 20, step 02 can be implemented by the second determination module 30, step 03 can be implemented by the third determination module 40, step 04 can be implemented by the fourth determination module 50, and step 05 can be implemented by the control module 60. That is to say, the first determination module 20 can be used to determine the reference current and the preset reference value; the second determination module 30 can be used to determine the sum of the brightness values ​​of all pixel points corresponding to the picture to be displayed to obtain the data statistical value; the third determination module 40 can be used to determine the quotient of the preset reference value and the data statistical value to obtain the balance coefficient, and the balance coefficient is greater than or equal to 1; the fourth determination module 50 can be used to determine the product of the reference current and the balance coefficient as the actual current, and the actual current is greater than or equal to the reference current; the control module 60 can be used to control the display module 10 to display the picture to be displayed with the actual current.

[0033] Among them, the display module 10 can be an LED (Light Emitting Diode) module, a MiniLED module, an OLED (Organic Light-Emitting Diode) module or an LCD (Liquid Crystal Display) module, etc. The sum of the brightness values ​​of all pixels corresponding to any picture to be displayed is less than or equal to the preset reference value, that is, the data statistical value is less than or equal to the preset reference value, so the balance coefficient obtained by dividing the preset reference value by the data statistical value is greater than or equal to 1, so the actual current obtained by multiplying the balance coefficient by the reference current is greater than or equal to the reference current. Since the higher the current used by the display module 10 when the picture to be displayed is the same, the higher the brightness of the picture to be displayed, so using the actual current to display the picture to be displayed can improve the brightness of the display module 10 when displaying the picture to be displayed. In addition, for the LED module, when the reference current flows through the LED, due to the small reference current, the luminous efficiency of the LED is low, which affects the display effect of the low grayscale picture. In one embodiment, the display module 10 is an LED module. Due to the increase of the actual current, when the actual current flows through the LED, the luminous efficiency of the LED is improved, so that the display effect of the low grayscale picture is improved.

[0034] In addition, different pictures to be displayed have different data statistics. Since the balance coefficient is the quotient of the preset reference value and the data statistics, the data statistics and the balance coefficient are inversely proportional. For pictures to be displayed with larger data statistics, the corresponding balance coefficient is smaller, that is, the actual current of the pictures to be displayed with larger data statistics is smaller than the reference current, and the display module has a smaller display brightness when displaying pictures with larger data statistics. The balance coefficient calculated based on the pictures to be displayed with smaller data statistics is larger, and the actual current obtained is larger than the reference current. When the display module displays the pictures to be displayed with smaller data statistics, the display brightness is larger. The actual power can be equivalent to the product of the data statistics, the balance coefficient and the reference current, and the product of the data statistics and the balance coefficient is the preset reference value. When the preset reference value and the reference current are fixed values, the actual power is also fixed value, which is equal to the reference power.

[0035] In this way, the power balancing method controls the display module 10 to work by an actual current greater than or equal to the reference current, and can improve the brightness of the display module 10 when displaying the picture to be displayed. Since the reference power is the product of the preset reference value and the reference current, the actual power is the product of the data statistical value and the actual current, that is, the actual power is the product of the data statistical value, the balance coefficient and the reference current, and the balance coefficient is the quotient of the preset reference value and the data statistical value, the actual power is the product of the preset reference value and the reference current, that is, the actual power is equal to the reference power, so that the brightness of the display module 10 can be improved while maintaining the power consumption of the display module 10 unchanged.

[0036] See also Figure 3 In some embodiments, step 01 (determining a reference current and a preset reference value) includes:

[0037] 011: Determine a preset reference value, where the preset reference value is the sum of the brightness values ​​of all pixels when the display module 10 displays a pure white image.

[0038] 012: Setting a reference current according to standard brightness. The reference current is a current that controls the display module 10 to reach the standard brightness when displaying a pure white image.

[0039] Specifically, the first determination module 20 includes a first determination submodule and a second determination submodule. Step 011 can be implemented by the first determination submodule, and step 012 can be implemented by the second determination submodule. That is to say, the first determination submodule can be used to determine a preset reference value, which is the sum of the brightness values ​​of all pixels of the display device 10 display module 10 when displaying a pure white picture; the second determination submodule can be used to set a reference current according to the standard brightness, and the reference current is the current that controls the display device 10 display module 10 to reach the standard brightness when displaying a pure white picture.

[0040] In addition, when the screen is pure white, the brightness value of each pixel is 255. If there are n pixels, the preset reference value is the sum of n 255s, which is the product of n times 255. The reference current includes RGB current. For the same display module 10, when the standard brightness is different, the RGB current is different, and the standard brightness can be set according to the actual situation. For the same standard brightness, the display module 10 is different, and the RGB current is also different. For example, for the Mini LED display module 10 with a PCB substrate and a dot pitch of 0.9mm, when the standard brightness is 500nit, the RGB currents are 0.68mA, 0.5mA, and 0.35mA respectively; for the Mini LED display module 10 with a glass substrate and a dot pitch of 0.9mm, when the standard brightness is 500nit, the RGB currents are 45uA, 24uA, and 22uA respectively.

[0041] In this way, the preset reference value can be obtained by summing the brightness values ​​of all pixels corresponding to the pure white picture, and the reference current is set by the standard brightness, so that the reference current is used to control the display module 10 to display the pure white picture to achieve the current of the standard brightness.

[0042] See also Figure 3 In some embodiments, step 02 (determining the sum of the brightness values ​​of all pixels corresponding to the image to be displayed as a data statistic) includes:

[0043] 021: Get the brightness values ​​of all pixels corresponding to the image to be displayed. The brightness values ​​are binary data.

[0044] 022: Convert the brightness value to decimal data.

[0045] 023: Determine the sum of all brightness values ​​converted to decimal data to obtain data statistics.

[0046] Specifically, the second determination module 30 includes a third determination submodule, a fourth determination submodule and a fifth determination submodule, step 021 can be implemented by the third determination submodule, step 022 can be implemented by the fourth determination submodule, and step 023 can be implemented by the fifth determination submodule. The brightness values ​​of all pixels corresponding to the image to be displayed are binary data. To facilitate subsequent calculations, the brightness values ​​of the binary data are converted to decimal data brightness values, and the decimal data brightness values ​​are summed to obtain data statistics values, which are decimal data.

[0047] In addition, the brightness value can be converted from binary to decimal to obtain a data statistical value, and a balance coefficient is obtained by using the data statistical value and a preset reference value. The actual current obtained by multiplying the balance coefficient by the reference current is displayed to achieve improved brightness.

[0048] See also Figure 4 In some embodiments, the power balancing method further comprises:

[0049] 06: Determine the product of the preset coefficient and the reference current as the preset current.

[0050] 07: When the actual current value is greater than the preset current value, the preset current value is used as the actual current value.

[0051] Specifically, the display device 100 further includes a fifth determination module and a sixth determination module, step 06 can be implemented by the fifth determination module, and step 07 can be implemented by the sixth determination module. That is, the fifth determination module can be used to determine the product of the preset coefficient and the reference current as the preset current; the sixth determination module can be used to use the preset current value as the actual current value when the actual current value is greater than the preset current value.

[0052] In addition, a preset coefficient is set in advance, and the preset coefficient is multiplied by the reference current to obtain a preset current, and the preset current is the maximum current that the current of the set display module can reach. Setting the maximum current can protect the circuit and prevent the circuit from being damaged due to the influence of large current, and the maximum brightness can be set by setting the maximum current. When the maximum current is used for display, the maximum brightness of the image to be displayed is reached, thereby controlling power consumption. When the maximum current is set with the preset coefficient, due to the different display efficiencies of the display module 10, the maximum brightness may be higher than the brightness that can be achieved by displaying the current obtained by multiplying the preset coefficient by the reference current.

[0053] In this way, by setting the preset coefficient, the product of the preset coefficient and the reference current can be determined to obtain the maximum current, and when the actual current is greater than the maximum current, the value of the maximum current is used as the value of the actual current, thereby protecting the circuit from high current.

[0054] See also Figure 5 In some embodiments, the preset coefficient is 2, and step 07 (when the actual current value is greater than the maximum current value, setting the actual current value to the maximum current value) includes:

[0055] 071: When the actual current is greater than twice the reference current, the actual current value is set to twice the reference current value.

[0056] Specifically, the sixth determination module includes a sixth determination submodule, and step 071 can be implemented by the sixth determination submodule, that is, the sixth determination submodule can be used to set the value of the actual current to twice the value of the reference current when the actual current is greater than twice the reference current.

[0057] In addition, this embodiment is explained using the display module 10 as an LED module. Since the LED has higher luminous efficiency under a large current, when the preset coefficient is 2, the preset current is twice the reference current. As the current increases, the luminous efficiency of the LED increases. The brightness displayed by the LED under twice the reference current is more than twice that when displayed with the reference current. The maximum brightness that the display module 10 can achieve is greater than twice the standard brightness.

[0058] Thus, when the preset coefficient is 2, the maximum brightness that the display module 10 can achieve is greater than 2 times the standard brightness, which enables the display module 10 to achieve a higher brightness display.

[0059] See also Figure 6 In some embodiments, the power balancing method further comprises:

[0060] 08: Determine a preset current according to a preset brightness, where the preset brightness is the brightness achieved when the display module 10 displays with the preset current.

[0061] 09: When the actual current value is greater than the preset current value, the preset current value is used as the actual current value.

[0062] Specifically, the display device 100 further includes a seventh determination module and an eighth determination module, step 08 can be implemented by the seventh determination module, and step 09 can be implemented by the eighth determination module. That is, the seventh determination module can be used to determine the preset current according to the preset brightness, and the preset brightness is the brightness reached when the display module 10 displays with the preset current; the eighth determination module can be used to use the preset current value as the actual current value when the actual current value is greater than the preset current value.

[0063] In addition, a preset brightness is set in advance, and the preset brightness is the maximum brightness that the display module 10 can reach. Then, a preset current is determined according to the maximum brightness, and the preset current is the maximum current that the current of the set display module can reach. When the actual current value is greater than the maximum current value, the maximum current value is used as the actual current value, so that the current of the display module 10 does not exceed the maximum current. Since the maximum current is obtained according to the preset brightness, when displaying with the maximum current, the maximum brightness that the display module 10 can reach is the preset brightness. However, different display modules 10 have different display efficiencies. Therefore, when the display module 10 displays the image to be displayed, the power consumption of the display module 10 when it reaches the maximum brightness may be less than the product of the power consumption of the display module 10 when it reaches the standard brightness and the maximum coefficient. For example, when the display module 10 is an LED module, the standard brightness is 500nit, and the preset brightness is 1000nit, the preset brightness is twice the standard brightness. Since the LED has a higher luminous efficiency under a large current, the brightness that the display module 10 can achieve when displaying with a current of twice the reference current is higher than the preset brightness. The maximum current corresponding to the preset brightness is less than 2 times the reference current. Therefore, the power consumption of the display module 10 when it reaches the maximum brightness is lower than 2 times the power consumption of the display module 10 when it reaches the standard brightness.

[0064] In this way, by setting the preset brightness and then determining the maximum current according to the preset brightness, the maximum brightness that the display module 10 can reach can be determined, and at the same time, the power consumption of the display module 10 for increasing the brightness can be reduced.

[0065] In some implementations, when the picture to be displayed is a pure white picture, the balance coefficient is 1; when the picture to be displayed is not a pure white picture, the balance coefficient is greater than 1.

[0066] Specifically, since the preset reference value is the sum of the brightness values ​​of all pixels corresponding to the pure white picture, and the brightness value of all pixels corresponding to the pure white picture is 255, the preset reference value is the product of the number of pixels and 255. When the picture to be displayed is a pure white picture, the brightness value of all pixels corresponding to the picture to be displayed is 255, and the data statistical value is the product of the number of pixels and 255, then the quotient of the preset reference value and the data statistical value is 1, that is, the balance coefficient is 1; when the picture to be displayed is not a pure white picture, at least one of the brightness values ​​of the pixels corresponding to the picture to be displayed is less than 255, so the data statistical value is less than the product of the number of pixels and 255, so the data statistical value is less than the preset reference value, and the quotient of the preset reference value and the data statistical value is greater than 1, that is, the balance coefficient is greater than 1.

[0067] In this way, by controlling the balance coefficient to be 1 when the image to be displayed is a pure white image, the display brightness of the display module 10 will not be increased when the image is a pure white image; by controlling the balance coefficient to be greater than 1 when the image to be displayed is not a pure white image, the display brightness of the display module 10 will be increased in other images, thereby selectively increasing the brightness, thereby achieving the goal of improving the brightness of the display image while controlling the maximum power of the display module 10 to remain unchanged.

[0068] See also Figure 7 In some embodiments, step 02 (determining the sum of the brightness values ​​of all pixels corresponding to the image to be displayed as a data statistic) includes:

[0069] 024: Get the brightness values ​​of all pixels corresponding to the image to be displayed;

[0070] Step 04 (determining the product of the reference current and the balance coefficient as the actual current) includes:

[0071] 041: When the brightness values ​​of all pixels are the same, set the balance coefficient to 1.

[0072] 042: Use the reference current value as the actual current value.

[0073] Specifically, the fourth determination module includes a seventh determination submodule and an eighth determination submodule, step 024 can be implemented by the third determination submodule, step 041 can be implemented by the seventh determination submodule, and step 042 can be implemented by the eighth determination submodule. In other words, the third determination submodule can be used to obtain the brightness values ​​of all pixels corresponding to the image to be displayed; the seventh determination submodule can be used to set the balance coefficient to 1 when the brightness values ​​of all pixels are the same; and the eighth determination submodule can be used to use the value of the reference current as the value of the actual current.

[0074] In addition, after obtaining the brightness values ​​of all pixel points corresponding to the image to be displayed, the brightness values ​​are compared. If the brightness values ​​of all pixel points are the same, it means that the image to be displayed is a gray solid color image. In order to reduce power consumption, the brightness of the gray solid color image is not increased. Therefore, the balance coefficient is set to 1, and the value of the reference current is used as the value of the actual current. The display module 10 displays the gray solid color image with the reference current.

[0075] In this way, when the brightness values ​​of all pixels corresponding to the image to be displayed are the same, the balance coefficient is set to 1, and the value of the reference current is used as the value of the actual current, and the image to be displayed is displayed with the reference current, thereby reducing the power consumption of the display module 10.

[0076] An embodiment of the present invention provides an electronic device, which includes one or more processors and a memory. The memory stores a computer program. When the computer program is executed by the processor, the steps of the power balancing method in any of the above embodiments are implemented.

[0077] In this way, the electronic device controls the display module 10 to work by an actual current greater than or equal to the reference current, and can improve the brightness of the display module 10 when displaying the picture to be displayed. Since the reference power is the product of the preset reference value and the reference current, the actual power is the product of the data statistical value and the actual current, that is, the actual power is the product of the data statistical value, the balance coefficient and the reference current, and the balance coefficient is the quotient of the preset reference value and the data statistical value, the actual power is the product of the preset reference value and the reference current, that is, the actual power is equal to the reference power, so that the brightness of the display module 10 can be improved while maintaining the power consumption of the display module 10 unchanged.

[0078] An embodiment of the present invention provides a computer-readable storage medium, and when the program is executed by a processor, the steps of the power balancing method in any of the above embodiments are implemented.

[0079] In this way, the computer-readable storage medium controls the display module 10 to work by an actual current greater than or equal to the reference current, and can improve the brightness of the display module 10 when displaying the picture to be displayed. Since the reference power is the product of the preset reference value and the reference current, the actual power is the product of the data statistical value and the actual current, that is, the actual power is the product of the data statistical value, the balance coefficient and the reference current, and the balance coefficient is the quotient of the preset reference value and the data statistical value, the actual power is the product of the preset reference value and the reference current, that is, the actual power is equal to the reference power, so that the brightness of the display module 10 can be improved while maintaining the power consumption of the display module 10 unchanged.
