[0002] LED (Light Emitting Diode) display screens are widely used in various fields. An LED display screen realizes full-color and full-pixel display by cooperation of RGB. However, since the area of an LED display screen is usually large, and the power supply mode of a row and column driving chip is mostly unified and direct power supply, the LED screen is rarely powered off when it is in a standby state. Therefore, power consumption has always been a prominent problem in the LED industry.

[0003] In the prior art, a scheme is usually considered that when a gray value of video data is less than a certain threshold, it is determined that the display screen enters an energy-saving mode, so as to power off the row and column driving chip, thereby achieving the purpose of energy saving. However, by using this method, the detection result is one-sided, and the influence of the light-emitting condition under different ambient light is not considered. SUMMARY

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] It should be noted that the terms "first," "second," "target," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] Example 1

[0036] Figure 1 This is a flowchart of a method for determining an energy-saving mode according to Embodiment 1 of the present invention. This embodiment is applicable to situations where it is necessary to accurately determine whether a display screen has entered an energy-saving mode under different environments. This method can be executed by an energy-saving mode determining device, which can be implemented in hardware and / or software. This energy-saving mode determining device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0037] S110, determine the light intensity of each LED in the target area in each component based on the individual light intensity of each LED in the target area of ​​the display screen.

[0038] Here, "display screen" can refer to an LED display screen. An LED display screen can achieve full-color, full-pixel display by using LEDs of three different colors: R (red), G (green), and B (blue). The target area can refer to the region of interest on the display screen, serving as the basis for determining whether the display screen has entered energy-saving mode. For example, the target area can be the region on the display screen corresponding to video frame data, i.e., the area on the display screen capable of playing video frame data; it can also be a region obtained by dividing the entire display screen area into blocks. "Components" can refer to the three color components: R, G, and B.

[0039] Here, "LED bead" refers to the external LED beads on the display screen hardware. "Single LED light intensity" refers to the light intensity of a single LED bead in a target area, used to characterize the brightness of that single LED bead in the target area. LED bead light intensity can refer to the single LED light intensity of the target area in the R, G, and B components. It should be noted that different displays may use different LED bead models, and different models of LED beads correspond to different LED bead information. Therefore, the LED bead information may differ between different displays, and the specific information needs to be determined based on the LED bead model of the display screen.

[0040] In this embodiment, optionally, the light intensity of the LEDs in each component of the target area is determined based on the individual light intensity of each LED corresponding to the target area of ​​the display screen, including: determining the individual light intensity of each LED corresponding to the target area of ​​the display screen; and determining the light intensity of the LEDs in each component of the target area based on the current value of the LED in each component and the relationship between the current value of each component and the relative light intensity obtained in advance.

[0041] In this embodiment, the individual light intensity of each LED in the target area is first determined based on the LED information of the target area. Optionally, determining the individual light intensity of each LED in the target area of ​​the display screen includes: determining the regional light intensity of the target area of ​​the display screen; and determining the individual light intensity based on the regional light intensity, the LED density in the target area, and the number of scans. The regional light intensity can refer to the white balance brightness of the target area, and the LED density can refer to the number of LEDs per square meter in the target area. For example, the individual light intensity can be calculated using the following formula: [(Iv×n) / a]×80%=Ivm. Where Iv represents the individual light intensity, n represents the LED density in the target area, a represents the number of scans, and Ivm represents the regional light intensity. For example, assuming the regional light intensity Ivm is 700 cd and the LED density n in the target area is 640,000 dots / m². 2 When the number of scans a is 64, the intensity of a single lamp is: Iv = Ivm ÷ 80% × a ÷ n = 87.5 mcd.

[0042] After determining the individual light intensity of each LED in the target area, the current value of each LED in each component can be determined based on the LED information on the display screen. Then, based on the pre-acquired relationship between the current value of each component and its relative light intensity, the relative light intensity of each component is determined, and thus the proportional relationship between the relative light intensities of each component is determined. Finally, the individual light intensities are proportionally allocated according to the proportional relationship between the relative light intensities of each component, thereby determining the LED light intensity in each component of the target area. It should be noted that, in order to easily adapt to LED information (LED parameters) of different models from various manufacturers, a characteristic dashed line table can be created based on the relationship between the current value of each component and its relative light intensity, and the characteristic dashed line table can be imported into the PC (Personal Computer).

[0043] Figure 2 This is a schematic diagram illustrating the relationship between the current values ​​of each component and the relative light intensity, as provided in Embodiment 1 of the present invention. For example, assuming the current values ​​of the LED bead in the R, G, and B components are I(R) = 5mA, I(G) = 2.5mA, and I(B) = 2.5mA respectively, if the relationship between the current values ​​of each component and the relative light intensity satisfies... Figure 2 The relationship between them is... Figure 2 The relative light intensities of the R, G, and B components can be obtained separately, and the ratio of the relative light intensities of the three components can be determined as Iv(R)∶Iv(G)∶Iv(B)=3∶6∶1. Assuming the intensity of a single lamp is 87.5 mcd, the lamp light intensities in each component of the target area can be determined by proportional allocation as follows: Lamp(R)=26.25 mcd, Lamp(G)=52.5 mcd, Lamp(B)=8.75 mcd.

[0044] This solution, through this configuration, can quickly and accurately determine the light intensity of LEDs in each component of a target area for displays with different LED information, based on the individual light intensity of each LED in the target area, the current value of the LED in each component, and the relationship between the current value of each component and the relative light intensity.

[0045] S120, calculate the black factor for each component based on the video grayscale value and LED light intensity of the target area in each component.

[0046] Among them, video grayscale values ​​can be used to characterize the brightness of the video displayed on the screen. Understandably, the smaller the video grayscale value, the lower the video brightness; the larger the video grayscale value, the higher the video brightness. The black factor can be used to represent the degree of blackness in a target area, and can be determined by the video grayscale values ​​of the target area in each component and the light intensity of the LED beads.

[0047] In this embodiment, after determining the light intensity of the LEDs in each component of the target area, the original video grayscale value of the target area on the display screen can be obtained. Then, the original video grayscale value is converted to R, G, and B components to determine the video grayscale value of the target area on the display screen in each component. The conversion method can be found in the prior art, and this embodiment is not limited thereto.

[0048] In this embodiment, optionally, the black factor of each component is calculated based on the video grayscale value and LED light intensity of the target region in each component, including: the sum of the product of the video grayscale value and the video grayscale value weight of the target component and the product of the LED light intensity and the LED light intensity weight of the target component is used as the black factor of the target component.

[0049] The target component can refer to any one of the R, G, and B components. The video grayscale weight and the LED light intensity weight can be used to characterize the proportion of video grayscale value and LED light intensity in the black factor calculation, respectively. For example, the video grayscale weight can be set to 0.7, and the LED light intensity weight can be set to 0.3, i.e., video grayscale weight : LED light intensity weight = 7 : 3. In this embodiment, the black factor of the target component can be represented as follows:

[0050] Y(R / G / B)=x×Data(R / G / B)+y×Lamp(R / G / B);

[0051] Where Y represents the black factor of the target component, x and y represent the video grayscale weight and LED light intensity weight, respectively, Data and Lamp represent the video grayscale value and LED light intensity of the target component, respectively, and R, G, and B represent the three components. In other words, the black factor uses grayscale value weight and LED light intensity weight to represent the degree of black screen in the target area.

[0052] This solution uses this setting to determine the black factor of the target component based on both internal display data (the grayscale value of the target component's video) and external data (the luminous intensity of the target component's LEDs). This allows for subsequent judgment on whether the target component should enter energy-saving mode based on the black factor of the target component, improving the accuracy of the energy-saving mode judgment and enabling flexible responses to the impact of different environments.

[0053] S130: Based on the black factor of the target component and the preset black factor threshold, determine whether the target component should enter the energy-saving mode.

[0054] The black factor threshold can refer to a pre-set black factor reference value, which can be set according to actual needs; this embodiment does not limit this. Optionally, the process of determining the black factor threshold includes: determining the black factor threshold based on the current ambient brightness and the LED temperature of each LED corresponding to the target area. It should be noted that since the LED models of different displays may differ, i.e., the LED information of different displays may be different, and the black factor is affected by the current ambient brightness and LED temperature, the black factor threshold can be dynamically determined based on the current ambient brightness and the LED temperature of each LED corresponding to the target area to adapt to displays with different LED models. Through this setting, this solution can dynamically and adaptively adjust the black factor threshold based on the current ambient brightness and the LED temperature of each LED corresponding to the target area for displays with different LED models. This allows for subsequent judgment on whether the target component enters energy-saving mode based on the black factor threshold, thereby improving the accuracy of the target component energy-saving mode judgment.

[0055] In this embodiment, after determining the black factor of the target component, the black factor of the target component can be compared with a preset black factor threshold, and the target component can be determined to enter the power-saving mode based on the comparison result. For example, if the black factor of the target component is less than or equal to the preset black factor threshold, it indicates that the brightness of the target component's image is very low or even completely black, and it can be determined that the target component has entered the power-saving mode; if the black factor of the target component is greater than the preset black factor threshold, it indicates that the image of the target component has a certain brightness, and it can be determined that the target component has not entered the power-saving mode.

[0056] The technical solution of this invention determines the LED light intensity of the target area in each component based on the individual light intensity of each LED corresponding to the target area of ​​the display screen; calculates the black factor for each component based on the video grayscale value and LED light intensity of the target area, where the black factor represents the degree of black screen in the target area; and determines whether the target component enters energy-saving mode based on the black factor of the target component and a preset black factor threshold. This technical solution, by combining video grayscale information and LED light intensity to determine the black factor of the target area of ​​the display screen in each component, comprehensively determines whether to enter energy-saving mode based on the black factor, and implements component control for RGB, enabling flexible responses to the impact of different environments.

[0057] Example 2

[0058] Figure 3 This is a flowchart of a method for determining an energy-saving mode according to Embodiment 2 of the present invention. This embodiment is an optimization based on the above embodiment. Specifically, the optimization is as follows: the target area is the area on the display screen corresponding to the video frame data; based on the black factor of the target component and a preset black factor threshold, it is determined whether the target component enters the energy-saving mode, including: if it is determined that the black factor of the target component of a consecutive preset number of video frame data is less than or equal to the preset black factor threshold, and a synchronization signal is received, then it is determined that the target component enters the energy-saving mode.

[0059] like Figure 3 As shown, the method in this embodiment specifically includes the following steps:

[0060] S210: Determine the light intensity of each LED in the target area in each component based on the individual light intensity of each LED in the target area of ​​the display screen.

[0061] The target area is the region on the display screen that corresponds to the video frame data.

[0062] S220: Calculate the black factor for each component based on the video grayscale value and LED light intensity of the target area in each component.

[0063] The specific implementation methods of S210-S220 can be found in the detailed description of S110-S120, and will not be repeated here.

[0064] S230, if it is determined that the black factor of the target component of a consecutive preset number of video frame data is less than or equal to the preset black factor threshold, and a synchronization signal is received, then it is determined that the target component enters the energy-saving mode.

[0065] The preset quantity can refer to a pre-defined quantity parameter, which can be used to characterize the number of video frames in which the black factor of the target component of the video frame data is less than or equal to a preset black factor threshold. For example, the preset quantity can be set to 2. The synchronization signal can refer to a clock division period signal, which is used to count the duration for which the black factor of the target component of the video frame data is less than or equal to the preset black factor threshold.

[0066] In this embodiment, assuming a preset quantity of 2, the black factor Y1 of the target component of the first video frame data is first read in, and it is determined whether Y1 is less than or equal to a preset black factor threshold. If so, Y1 is recorded as 1; otherwise, it is recorded as 0. Then, the black factor Y2 of the target component of the second video frame data is continuously read in, and it is determined whether Y2 is less than or equal to a preset black factor threshold. If so, Y2 is recorded as 1; otherwise, it is recorded as 0. Furthermore, it is determined whether Y1 and Y2 are the same. If they are not the same, 0 is output; if they are the same, the AND result of Y1 and Y2 is output (1 if both are 1, 0 if both are 0).

[0067] Figure 4 This is a schematic diagram of a method for determining an energy-saving mode according to Embodiment 2 of the present invention. Figure 4 As shown, if the black factor judgment result of two consecutive frames is 1, it indicates that there are two consecutive frames where the black factor is less than or equal to the preset black factor threshold. At this time, the power-saving signal is 1. If a synchronization signal is received at the same time, it is determined that the target component enters the power-saving mode (such as the third frame); otherwise, it is determined that the target component does not enter the power-saving mode. The standby signal is the signal obtained by ANDing the synchronization signal and the power-saving signal. If the standby signal is 1, it indicates that the power-saving mode has been entered; if the standby signal is 0, it indicates that the power-saving mode has not been entered.

[0068] Furthermore, the enable time of the energy-saving signal can be predefined. If the energy-saving signal remains at 1 during the enable time, the standby signal is determined to be 1, and the energy-saving mode is entered. For example, the enable time can be 5 seconds. When the period of the synchronization signal is 1 second, if the energy-saving signal is 1 when 5 consecutive synchronization signals arrive, the standby signal is determined to be 1.

[0069] It should be noted that when entering energy-saving mode, the output disconnects the switching control module of the power supply branch, but the LED main control module still operates in a low-power state. The data signal in BankA is continuously updated, and the black factor of adjacent frames of data is compared in a loop until a frame of data ends, at which point it is determined whether to enter energy-saving mode. BankA (e.g., ...) Figure 5A (as shown) and Bank B (as shown) Figure 5B (As shown) are two processing storage banks of the FPGA's internal processing unit, which can be used to compare black factors. Figure 5A and Figure 5B The memory A shown is located in Bank A, and the memory B is located in Bank B.

[0070] It should be noted that the technical solution in this embodiment is applicable to the normal energy-saving mode, that is, it can determine the energy-saving mode based on the continuous video frame images when the screen is in low brightness or completely dark.

[0071] The technical solution of this invention defines the target area as the region on the display screen corresponding to video frame data. If the black factor of the target component of a consecutive preset number of video frame data is less than or equal to a preset black factor threshold, and a synchronization signal is received, then the target component is determined to be in energy-saving mode. This technical solution determines the black factor of the target area of ​​the display screen in each component by combining the video grayscale information of the region on the display screen corresponding to the video frame data and the light intensity of the LED beads. This allows for a comprehensive judgment on whether the display screen enters energy-saving mode based on the black factor, and enables component control of RGB, flexibly responding to the impact of different environments.

[0072] Example 3

[0073] Figure 6 This is a flowchart of a method for determining an energy-saving mode according to Embodiment 3 of the present invention. This embodiment is an optimization based on the above embodiment. Specifically, the optimization is as follows: the target area is the area obtained by dividing the display screen area into blocks; based on the black factor of the target component and a preset black factor threshold, it is determined whether the target component enters the energy-saving mode, including: if it is determined that the black factor of the target component in a consecutive preset number of target areas is less than or equal to the preset black factor threshold, a synchronization signal is received, and an energy-saving mode control signal is received, then it is determined that the target component in the target area enters the energy-saving mode.

[0074] like Figure 6 As shown, the method in this embodiment specifically includes the following steps:

[0075] S310 determines the light intensity of each LED in the target area in each component based on the individual light intensity of each LED in the target area of ​​the display screen.

[0076] The target area is the region obtained by dividing the display screen area into blocks. Figure 7 This is a schematic diagram of a target area provided in Embodiment 3 of the present invention. Figure 7 As shown, the display screen is divided into 10 LED blocks, each of which is a target area.

[0077] S320 calculates the black factor for each component based on the video grayscale value and LED light intensity of the target area in each component.

[0078] The specific implementation methods of S310-S320 can be found in the detailed description of S110-S120, and will not be repeated here.

[0079] S330: If it is determined that the black factor of the target component of a consecutive preset number of target areas is less than or equal to the preset black factor threshold, a synchronization signal is received, and an energy-saving mode control signal is received, then it is determined that the target component of the target area enters the energy-saving mode.

[0080] The power-saving mode control signal can be used to control whether the target component enters the power-saving mode. For example, the power-saving mode control signal can be an if signal. It should be noted that for a target area obtained by dividing the display screen area into blocks, a target area can be considered a matrix area. When a matrix area with all zeros (the target area is completely black), the if signal of the current video frame data, and the synchronization signal are detected simultaneously, the target component of that target area enters the power-saving mode.

[0081] In this embodiment, assuming the preset quantity is 2, it is first determined whether the black factor of the target component of two adjacent video frame data is less than or equal to the preset black factor threshold. Then, it is determined whether Y1 and Y2 are the same, and 0 or 1 is output according to the determination result. The black factor determination process can be found in the detailed description of S240 in the above embodiment two, and will not be repeated here.

[0082] Figure 8 This is a schematic diagram of a method for determining an energy-saving mode according to Embodiment 3 of the present invention. Figure 8 As shown, if the black factor judgment result of two consecutive frames is 1, it indicates that there are two consecutive frames where the black factor is less than or equal to the preset black factor threshold. If a synchronization signal and a power-saving mode control signal are received simultaneously, it is determined that the target component enters the power-saving mode (such as the third frame); otherwise, it is determined that the target component does not enter the power-saving mode. The data signal in BankA is continuously updated, and the data of two adjacent frames are compared in this loop until it is determined whether to enter the power-saving mode before the end of a frame.

[0083] Similarly, in this embodiment, the enable time of the energy-saving signal can also be set. If the energy-saving signal is always 1 during the enable time, the standby signal is determined to be 1, and the energy-saving mode is entered. For example, the enable time can be 5 seconds. When the period of the synchronization signal is 1 second, if the energy-saving signal is 1 when 5 consecutive synchronization signals arrive, and the energy-saving mode control signal is received in all of them, then the standby signal is determined to be 1.

[0084] It should be noted that the technical solution in this embodiment is applicable to the intelligent energy-saving mode, which divides the display screen into multiple target areas and judges each target area in the continuous video frame separately. When a target area is completely black, it can be determined that the target area enters the energy-saving mode, which further enhances the energy-saving effect.

[0085] In this invention's technical solution, the target area is a region obtained by dividing the display screen area into blocks. If it is determined that the black factor of the target component in a consecutive preset number of target areas is less than or equal to a preset black factor threshold, a synchronization signal is received, and an energy-saving mode control signal is received, then it is determined that the target component of the target area enters the energy-saving mode. This technical solution determines the black factor of the target area of ​​the display screen in each component by combining the video grayscale information of the region obtained by dividing the display screen area into blocks and the light intensity of the LED beads. This allows for a comprehensive judgment on whether the display screen enters the energy-saving mode based on the black factor, and enables component control of RGB, flexibly responding to the impact of different environments.

[0086] Figure 9 This is a schematic diagram of a system for determining an energy-saving mode according to Embodiment 3 of the present invention. Figure 9 As shown, the PC transmits video data of the target area unidirectionally to the transmitting box via HDMI, and communicates with the transmitting box via a TYPE-B interface. The transmitting box directly transmits the video RGB signal (the video grayscale values ​​of the target area in each component) and control signals to the receiving card. The receiving card on the HUB board directly transmits the RGB signal to the light board (avoiding time delay in the video data processing stage), and simultaneously transmits the RGB signal to the video information processing module. The video information processing module partitions the RGB signal matrix input to the light board (refreshing the directly supplied RGB signal to achieve zero-delay matching), and simultaneously outputs a switch signal matrix to the light board.

[0087] HDMI (High Definition Multimedia Interface) is a fully digital video and audio transmission interface that can transmit uncompressed audio and video signals. TYPEB refers to a Type-B interface of USB (Universal Serial Bus). HUB refers to a multi-port repeater. The video information processing module is located on the HUB board, and its hardware includes an FPGA, MCU, and CPLD. FPGA (Field Programmable Gate Array), MCU (multi-control unit), and CPLD (Complex Programmable Logic Device) are logic elements. The video information processing module's inputs are RGB signals and SPI communication signals, and its outputs are RGB matrix signals and switch matrix signals. Specifically, the video information processing module includes a logic control module and a switch control module.
