[0057] Reference Figure 2 This application provides an energy efficiency adjustment method, which includes:

[0058] Step S100: Obtain the energy efficiency index table of the equipment;

[0059] Step S200: Based on the energy efficiency index table, determine the first backlight value adjustment range of the device's screen conversion function;

[0060] Step S300: Limit the first backlight value adjustment range to obtain the second backlight value adjustment range of the device screen change function;

[0061] Step S400: Update the energy efficiency index table based on the second backlight value adjustment range.

[0062] In this embodiment, a specific application scenario may be:

[0063] Currently, the cost of televisions is increasing due to the rising cost of screens. In order to save on costs, television manufacturers have to lower the energy efficiency rating of their televisions. Therefore, there is a need for a method that can improve the energy efficiency of televisions without increasing hardware costs.

[0064] The specific steps are as follows:

[0065] Step S100: Obtain the energy efficiency index table of the equipment;

[0066] In this embodiment, the energy efficiency adjustment method is applied to an energy efficiency adjustment device.

[0067] In this embodiment, the device is a device with a display screen, including electronic devices such as televisions, mobile phones, and tablets. Each device's display screen has a corresponding energy efficiency index table, which is located in its corresponding screen parameter directory, panel_factory.ini. Figure 4The values ​​in the index table correspond one-to-one with the OSD backlight values. That is, the OSD backlight value of 0 corresponds to the value of PanelEnergyTable[0], and the OSD backlight value of 100 corresponds to the value of PanelEnergyTable

[100] . The value of PanelEnergyTable[index] ranges from 0 to 100. For example, when PanelEnergyTable

[100] = 10 and the OSD backlight value is 100, refer to... Figure 5 The range of its screen change is PanelEnergyTable

[100] -100. It should be noted that since the maximum value of the screen change cannot exceed the OSD manual backlight value, when the OSD manual backlight value is less than PanelEnergyTable[index], the maximum value of its screen change is the OSD manual backlight value, and it will not reach the value of PanelEnergyTable[index].

[0068] Step S200: Based on the energy efficiency index table, determine the first backlight value adjustment range of the device's screen conversion function;

[0069] In this embodiment, the device determines the first backlight value adjustment range of the device's screen-changing function based on the energy efficiency index table. The screen-changing function is a function implemented by the device using a screen-changing algorithm. Figure 6 The screen adjustment algorithm calculates the required backlight value by using a weighted algorithm to calculate the average value of the 32-level brightness histogram of the acquired image. The first backlight value adjustment range is the range of backlight value that the device's screen adjustment algorithm can adjust; that is, the required backlight value is within the first backlight value adjustment range.

[0070] Specifically, step S200 includes the following steps S210-S220:

[0071] Step S210: Based on the energy efficiency index table, determine the backlight index value and the first backlight PWM value;

[0072] In this embodiment, the device determines the backlight index value and the first backlight PWM value based on the energy efficiency index table, wherein the energy efficiency index table includes the backlight index value and the first backlight PWM value, with reference to... Figure 4 The energy efficiency index table, PanelEnergyTable[0] = 0, indicates that the backlight index value is 0 and the first backlight PWM value is 0. PanelEnergyTable[1] = 8, that is, the backlight index value is 8 and the first backlight PWM value is 1. The energy efficiency index table contains 101 backlight index values ​​and the first backlight PWM value.

[0073] Step S220: Determine the backlight index value as the maximum value of the first backlight value adjustment range, and determine the backlight PWM value as the minimum value of the first backlight value adjustment range, to obtain the first backlight value adjustment range of the device screen change function.

[0074] In this embodiment, the device determines the backlight index value as the maximum value of the first backlight value adjustment range and the backlight PWM value as the minimum value of the first backlight value adjustment range, thereby obtaining the first backlight value adjustment range of the device's screen adjustment function. Specifically, refer to... Figure 7 The Figure 7 This refers to the energy efficiency information in the device's function menu. The energy efficiency table index corresponds to the current backlight value (index value in PanelEnergyTable[index]). The PWM value corresponding to this index is the value of PanelEnergyTable[index]. A value of 65 indicates the PWM duty cycle when the minimum screen brightness is 65. The minimum backlight value is the PWM duty cycle when the OSD backlight value is 0. The maximum backlight value is the PWM duty cycle when the OSD backlight value is 100.

[0075] Step S300: Limit the first backlight value adjustment range to obtain the second backlight value adjustment range of the device screen change function;

[0076] In this embodiment, the device limits the first backlight value adjustment range to obtain a second backlight value adjustment range for the device's screen switching function. The second backlight value adjustment range is smaller than the first backlight value adjustment range, meaning that the second backlight value adjustment range is included within the first backlight value adjustment range. By limiting the backlight value adjustment range of the device's screen switching function, the energy efficiency index table of the device's screen switching function is modified, thereby increasing the power fluctuation value, reducing the device's power consumption, and thus improving the device's energy efficiency. This achieves the goal of improving the TV's energy efficiency without increasing hardware costs.

[0077] Specifically, step S300 includes the following steps S310-S340:

[0078] Step S310: Turn off the screen conversion function of the device, perform an energy efficiency test on the device, and calculate the first overall power of the device at present;

[0079] In this embodiment, the device disables the screen conversion function of the device, performs an energy efficiency test on the device, and calculates the first overall power of the device. The overall power is the power value obtained after energy efficiency calculation, as shown in the following formula:

[0080]

[0081] Among them, E ffThe energy efficiency rating of a television is indicated by: L (average screen brightness), S (effective luminous area of ​​the screen), and P (power efficiency). k Indicates the power consumption during startup; P s This indicates the signal processing power.

[0082] In this embodiment, by adjusting the backlight value range of the limiting device's screen switching function, the energy efficiency index table of the device's screen switching function is modified, thereby increasing the power fluctuation value and reducing the device's start-up power P. k This will improve the energy efficiency of the equipment.

[0083] Step S320: Determine the target adjustment power based on the first overall power;

[0084] In this embodiment, the device determines the target adjustment power based on the first overall power. The target adjustment power is the target power used to adjust the backlight value adjustment range of the screen change algorithm. According to expert experience, the target adjustment power = first overall power * 75%. It should be noted that it is not limited to 75% and can also be other integrals set by the user. No specific limitation is made here.

[0085] Specifically, step S320 includes the following steps S321-S322:

[0086] Step S321: Obtain target adjustment parameters based on expert experience;

[0087] Step S322: Integrate the first total power of the machine with the target adjustment parameter to obtain the target adjustment power.

[0088] In this embodiment, the device integrates the first overall power and the target adjustment parameter to obtain the target adjustment power. The target adjustment power is the target power used to adjust the backlight value adjustment range of the screen-changing algorithm. Based on expert experience, the target adjustment parameter is determined to be 75% of the first overall power, i.e., the target adjustment power = first overall power * 75%. It should be noted that it is not limited to 75%; other integral values ​​can be set by the user. No specific limitation is made here. Refer to Table 1 below:

[0089]

[0090]

[0091] Table 1

[0092] Step S330: Activate the screen switching function of the device, perform the energy efficiency test on the device, and determine the adjusted second backlight PWM value based on the screen switching function and the target adjustment power.

[0093] In this embodiment, the device activates the screen switching function of the device, performs the energy efficiency test on the device, and determines the adjusted second backlight PWM value based on the screen switching function and the target adjustment power.

[0094] Specifically, step S330 includes the following steps S331-S333:

[0095] Step S331: Activate the screen conversion function of the device and output gray field to the device;

[0096] In this embodiment, the device activates the screen conversion function of the device and outputs a gray field to the device. That is, after activating the screen conversion algorithm, the energy efficiency test is performed on the device. Specifically, the VG817 outputs a 33% gray field to perform the energy efficiency test on the device.

[0097] Step S332: When the device is in the gray field scenario, based on the screen change function, the backlight value of the device is adjusted within the first backlight value adjustment range, and the corresponding second overall power is calculated.

[0098] In this embodiment, when the device is in the gray field scenario, based on the screen adjustment function, the device adjusts the backlight value of the device within the first backlight value adjustment range and calculates the corresponding second overall power. Specifically, the OSD backlight value is adjusted according to the backlight value in the first column of Table 1 above. The selected backlight value is then adjusted, and the PWM value corresponding to the index in the energy efficiency table is adjusted so that the actual measured power is equal to or close to the power value in the third column of the table above. The PWM value corresponding to the index in the energy efficiency table is recorded, as shown in Table 2 below:

[0099]

[0100]

[0101] Table 2

[0102] The values ​​in the energy efficiency table are E[] in Table 2 above, totaling 101 numbers. These are the PWM values ​​corresponding to backlight values ​​of 0-100. Fill in the data from the fourth column of the table above into the corresponding positions; other data can be adjusted non-linearly. The energy efficiency index table is located in PanelEnergyTable in panel_factory.ini. It should be noted that only 11 values ​​are displayed in the table, while there are a total of 101 numbers.

[0103] Step S333: The backlight value within the preset range of the target adjustment power of the second whole machine is determined as the second backlight PWM value.

[0104] In this embodiment, the device determines the second backlight PWM value as the backlight value within the preset range of the target adjustment power when adjusting the power of the second whole machine. Specifically, it adjusts the OSD backlight value according to the backlight value in the first column of Table 1, selects the backlight, and then adjusts the PWM value corresponding to the index in the energy efficiency table so that the actual measured power is equal to or close to the power value in the third column of the table above (preset range).

[0105] Step S340: Based on the second backlight PWM value and the backlight index value, a second backlight value adjustment range for the device screen change function is formed.

[0106] In this embodiment, the device forms the second backlight value adjustment range of the device screen change function based on the second backlight PWM value and the backlight index value. For example, the second backlight PWM value of PanelEnergyTable

[100] is 8, that is, the second backlight value adjustment range of PanelEnergyTable

[100] is 8-100, while the original second backlight value adjustment range of PanelEnergyTable

[100] is 3-100, and a certain limit is applied.

[0107] Step S400: Update the energy efficiency index table based on the second backlight value adjustment range.

[0108] In this embodiment, the device updates the energy efficiency index table based on the second backlight value adjustment range, that is, updates each backlight value in the energy efficiency index table according to the second backlight value adjustment range.

[0109] This application provides an energy efficiency adjustment method. Compared with the high cost of improving television energy efficiency in existing technologies, this application obtains an energy efficiency index table for the device; based on the energy efficiency index table, determines a first backlight value adjustment range for the device's screen-changing function; limits the first backlight value adjustment range to obtain a second backlight value adjustment range for the device's screen-changing function; and updates the energy efficiency index table based on the second backlight value adjustment range. In other words, this application modifies the energy efficiency index table for the device's screen-changing function by limiting the backlight value adjustment range, thereby increasing the power fluctuation value, reducing the device's power consumption, and thus improving the device's energy efficiency. This achieves the goal of improving television energy efficiency without increasing hardware costs.

[0110] Based on the first embodiment described above, this application also provides another embodiment, wherein the energy efficiency adjustment method includes: applied to a television set, after the steps of limiting the first backlight value adjustment range to obtain a second backlight value adjustment range for the device's screen-changing function, and updating the energy efficiency index table based on the second backlight value adjustment range, the method includes the following step A100:

[0111] Step A100: Adjust the repeat rate of the DTV signal under the DTV channel to the preset value.

[0112] In this embodiment, the energy efficiency adjustment method is specifically applied to a television set. The replay rate of the 1080i50 and above timing DTV signals under the DTV channel is adjusted to a preset value, specifically 100%, which improves energy efficiency. Replay rate is an important indicator in television image testing; it refers to the ratio of the image program reproduced on the television screen to the image program transmitted by the television station. Replay rate is divided into vertical and horizontal replay rates. For example, if the horizontal effective image pixels are 720, but 680 pixels are actually displayed, the horizontal replay rate is 680 / 720. Generally, the replay rate of a television should be greater than 95%. In existing technologies, the replay rate is around 97%, but in this application, it is adjusted to 100%.

[0113] Specifically, step A100 includes the following steps A110-A120:

[0114] Step A110: Obtain a comparison image with a preset repetition rate;

[0115] In this embodiment, the device acquires a comparison image with a preset repetition rate, which can be acquired by the user uploading the image themselves.

[0116] Step A120: Play the test image on the television set and adjust the replay rate of the DTV signal under the DTV channel until the replay rate of the comparison image and the test image are consistent. Then the replay rate of the DTV signal is adjusted to the preset value.

[0117] In this embodiment, the device plays a test image on the television set and adjusts the repetition rate of the DTV signal under the DTV channel until the repetition rate of the comparison image and the test image are consistent. Then, the repetition rate of the DTV signal is adjusted to a preset value. Specifically, the device adjusts the horizontal size data and horizontal position data, and the vertical size data and vertical position data of the DTV signal under the DTV channel until the horizontal repetition rate and vertical repetition rate are preset values.

[0118] This application also provides another embodiment:

[0119] In the test scenario, if the current image is determined to be a nine-window image provided by the certification authority, and it is a nine-window image, the backlight can be set to maximum, and then the brightness can be increased through gamma bypass and PQ bypass. Specifically, when the average brightness L of the nine windows is greater than 250, the OSD backlight value needs to be adjusted so that the center brightness of the nine windows is equal to or close to 250. For example, if there are two screens, panel A and panel B, and both screens have an average brightness L of 90 when the backlight bl is 100, then panel A needs to adjust the backlight bl to 80 so that the center brightness of the nine windows is equal to 250, and panel B needs to adjust the backlight bl to 45 so that the center brightness of the nine windows is equal to 250. Following the adjustment method in step two above, the energy efficiency values ​​of panel A (0-80) and panel B (0-45) can be obtained. The adjustment method for the energy efficiency values ​​of panel A (81-100) and panel B (46-100) is as follows:

[0120] For panelA:

[0121] Considering the consistency of screen optics (the theoretical brightness deviation between the worst and best screens is 20%), for panel A, that is, if the screen we are testing belongs to the worst screen in panel A, considering the consistency of screen energy efficiency, we add 5% to the theoretical deviation, 80 + 80 * 25% = 100. We also need to calculate the energy efficiency values ​​from 81 to 100. That is, the PWM value corresponding to the index in the energy efficiency table for OSD backlight equal to 90 and 100 also needs to be debugged and written to the PanelEnergyTable in panel_factory.ini.

[0122] For panelB:

[0123] As described above, by adjusting the energy efficiency value of panel A, we can calculate the energy efficiency value that we need to calculate further: 45 + 45 * 25% = 56.25. That is, we need to adjust the PWM value PWM corresponding to the index in the energy efficiency table for OSD backlight values ​​of 50 and 56, and write it into the energy efficiency table.

[0124] When the backlight is 0, the power p when the screen is on is not equal to the calculated expected value p0, and adjusting the PWM value pwm to the minimum does not satisfy this condition. In this case, it is necessary to adjust the minimum backlight value bl to a smaller value, and then adjust the PWM value pwm to make p = p0. Then, manually adjust the backlight to 0 and check if the screen goes black. Next, set the screen to off and check if the screen goes black. If the screen does not go black, record the PWM value pwm and the minimum backlight value bl and write them to the corresponding files.

[0125] In test scenarios, energy efficiency can also be increased through gamma bypass and pq bypass actions.

[0126] Pq bypass action: Pq is an image display module in the system. This module is mainly responsible for the correspondence between specific colors and screen driver display, debugging some image-related registers, and debugging related image processing algorithms. In principle, after processing by the Pq module, the colors displayed on the screen will be more vivid, which helps the viewer's subjective experience. However, it will inevitably sacrifice some screen brightness. Therefore, the Pq bypass action can improve brightness to a certain extent.

[0127] Gamma bypass is a set of calibration data. Generally, the default gamma curve of a TV is a straight line. Due to certain screen characteristics, image quality will bend this curve to a certain extent to achieve the best display effect. Gamma bypass can return the screen to its default state, which can improve brightness to some extent.

[0128] This application also provides an energy efficiency adjustment device, referring to... Figure 3 The energy efficiency adjustment device includes:

[0130] The determining module 20 is used to determine the first backlight value adjustment range of the device's screen conversion function based on the energy efficiency index table;
