Description

顯示器的能源效率測試方法Display energy efficiency test method

本發明是關於一種顯示器的能源效率測試方法，且特別是關於一種具有自動亮度控制功能的顯示器的開機模式平均功耗的能源效率測試方法。 The present invention relates to an energy efficiency test method for a display, and more particularly to an energy efficiency test method for a power-on mode average power consumption of a display having an automatic brightness control function.

顯示器，例如電視機，為高度普及的用電器具，若能提升其能源使用效率，對節能減碳將有正面的助益。美國能源之星計畫或我國節能標章計畫等均有對電視機提出能源效率規範以及其測試方法。電視機的能源效率規範一般包括開機模式平均功耗以及待機-被動模式平均功耗。以美國能源之星計畫為例，電視機的開機模式平均功耗必須小於或等於最大可允許的開機模式平均功耗P_{ON_MAX}如下：P_{ON_MAX}=78.5×tanh[0.0005×(A-140)+0.038]+14，其中，P_{ON_MAX}單位為瓦特(W)，A為電視機的可視螢幕面積，單位為平方英吋。電視機的待機-被動模式平均功耗必須小於或等於0.5W。 Display, such as televisions, is a highly popular electrical appliance. If it can improve its energy efficiency, it will be of great help to save energy and reduce carbon. The US Energy Star program or China's energy-saving stamp program has proposed energy efficiency specifications for TV sets and their testing methods. TV energy efficiency specifications generally include the average power consumption of the boot mode and the average power consumption of the standby-passive mode. Taking the US Energy Star program as an example, the average power consumption of the TV's boot mode must be less than or equal to the maximum allowable boot mode average power consumption P _{ON_MAX} as follows: P _{ON_MAX} = 78.5 × tanh [0.0005 × (A-140) + 0.038]+14, where P _{ON_MAX} is in watts (W) and A is the visible screen area of the TV in square inches. The standby-passive mode average power consumption of the TV must be less than or equal to 0.5W.

以具有自動亮度控制功能的電視機為例，其開機模式平均功耗的能源效率測試方法包括：電視機開機並開啟自動亮度控制功能而啟動環境光感測器，然後等待電視機達到穩定狀態；在電視機上播放測試視訊，分別以光源照度為3、12、35與100勒克司(lux)直接照射於環境光感測器上各10分鐘之測試時間，量測其各別之功耗P₃、P₁₂、P₃₅與P₁₀₀；以及計算開機模式平均功耗P_ON=(P₃+P₁₂+P₃₅+P₁₀₀)/4。這樣的測試流程，執行一次就需要花費40分鐘以上。而且當開機模式平均功耗P_ON高於最大可允許的開機模式平均功耗P_{ON_MAX}，即測試數據不通過時，需要調整電視機的設定，例如調整與各個環境亮度對應的亮度調整比率，然後重新執行上述測試流程，直到測試數據通過為止。因此，現有的電視機的開機模式平均功耗的能源效率測試方法相當耗費時間。 Taking a television with automatic brightness control as an example, the energy efficiency test method for the average power consumption of the boot mode includes: turning on the TV and turning on the automatic brightness control function to activate the ambient light sensor, and then waiting for the TV to reach a steady state; The test video is played on the TV, and the respective power consumption is measured by direct illumination of the light source illumination of 3, 12, 35 and 100 lux on the ambient light sensor for 10 minutes. ₃ , P ₁₂ , P ₃₅ and P ₁₀₀ ; and calculate the average power consumption of the boot mode P _ON = (P ₃ + P ₁₂ + P ₃₅ + P ₁₀₀ ) / 4. Such a test process takes more than 40 minutes to execute once. Moreover, when the power-on mode average power consumption P _{ON is} higher than the maximum allowable power-on mode average power consumption P _{ON_MAX} , that is, when the test data does not pass, it is necessary to adjust the setting of the television, for example, adjusting the brightness adjustment ratio corresponding to each ambient brightness, and then Re-execute the above test process until the test data passes. Therefore, the energy efficiency test method of the average power consumption of the power-on mode of the existing television set is quite time consuming.

請參見圖1，圖1為本發明一實施例之顯示器的能源效率測試方法之流程圖。顯示器例如是電視機，但不限於此。顯示器具有自動亮度控制功能以及區域調光功能。自動亮度控制功能讓顯示器在環境光感測器感測到環境亮度較低時調降畫面亮度，而在環境亮度較高時調高畫面亮度，可節能省電。區域調光功能讓顯示器根據電視機播放的視訊內容，在畫面上較暗區域提供較低背光亮度，而在畫面上較亮區域提供較高背光亮度，可提高畫面動態對比度。 Please refer to FIG. 1. FIG. 1 is a flowchart of a method for testing an energy efficiency of a display according to an embodiment of the present invention. The display is, for example, a television set, but is not limited thereto. Display with automatic brightness control And regional dimming function. The automatic brightness control function allows the display to reduce the brightness of the picture when the ambient light sensor senses that the ambient brightness is low, and increases the brightness of the picture when the ambient brightness is high, which saves energy. The area dimming function allows the display to provide a lower backlight brightness in the darker areas of the screen based on the video content played on the TV, and a higher backlight brightness in the brighter areas of the screen to improve the dynamic contrast of the picture.

顯示器的能源效率測試方法包括：在步驟S1，執行評估軟體以得到顯示器的開機模式平均功耗的評估值P_{ON_E}。步驟S1包括步驟S11~S15。 The energy efficiency test method of the display includes: at step S1, performing an evaluation software to obtain an evaluation value P _{ON_E} of the power-on mode average power consumption of the _display . Step S1 includes steps S11 to S15.

在步驟S11，評估軟體分析測試視訊的內容以得到測試視訊在測試時間內k個畫面的平均像素值分布。此平均像素值分布包括m個平均像素值區段，所述k個畫面根據各自的平均像素值分布於所述m個平均像素值區段，使所述m個平均像素值區段分別對應有m個畫面數量N₁、N₂、...、N_m，N₁+N₂+...+N_m=k。其中，k、m均為正整數，N₁、N₂、...、N_m均為非負整數。 In step S11, the content of the software analysis test video is evaluated to obtain an average pixel value distribution of the k pictures of the test video during the test time. The average pixel value distribution includes m average pixel value segments, and the k pictures are distributed according to the respective average pixel values in the m average pixel value segments, so that the m average pixel value segments respectively correspond to m number of pictures N ₁ , N ₂ , ..., N _m , N ₁ + N ₂ + ... + N _m = k. Where k and m are positive integers, and N ₁ , N ₂ , ..., N _m are all non-negative integers.

在步驟S12，在評估軟體中對顯示器的開機預設亮度值U、與n個環境亮度分別對應的n個第一亮度調整比率S₁、S₂、...、S_n以及與所述m個平均像素值區段分別對應的m個第二亮度調整比率D₁、D₂、...、D_m進行設定。其中，n為正整數，U、S₁、S₂、...、S_n、D₁、D₂、...、D_m均為0~100%(或0~1)。所述n個環境亮度可對應於顯示器的開機模式平均功耗的能源效率測試方法中所要求的多個光源照度，例如是3、12、35與100勒克司。需要說明的是，第一亮度調整比率S₁、S₂、...、S_n分別對應照度由低到高依序排列的n個環境亮度，第二亮度調整比率D₁、D₂、...、D_m分別對應平均像素值由低到高依序排列的m個平均像素值區段，而為了畫面整體平順起見，在進行設定或調整時，必須保持S₁≦S₂≦...≦S_n，D₁≦D₂≦...≦D_m。 In step S12, the boot preset brightness value U of the display in the evaluation software, n first brightness adjustment ratios S ₁ , S ₂ , . . . , S _n corresponding to the n ambient brightnesses, and the m The m second brightness adjustment ratios D ₁ , D ₂ , . . . , D _m corresponding to the average pixel value segments are set. Where n is a positive integer, and U, S ₁ , S ₂ , ..., S _n , D ₁ , D ₂ , ..., D _m are all 0 to 100% (or 0 to 1). The n ambient brightnesses may correspond to a plurality of light source illuminances required in an energy efficiency test method for a power-on mode average power consumption of the display, such as 3, 12, 35, and 100 lux. It should be noted that the first brightness adjustment ratios S ₁ , S ₂ , . . . , S _n respectively correspond to n ambient brightnesses in which the illuminance is sequentially arranged from low to high, and the second brightness adjustment ratios D ₁ , D ₂ , . .., D _m respectively correspond to m average pixel value segments in which the average pixel values are sequentially arranged from low to high, and for the overall smoothness of the screen, S ₁ ≦S ₂ ≦ must be maintained when setting or adjusting. ..≦S _n , D ₁ ≦D ₂ ≦...≦D _m .

在步驟S13，評估軟體根據顯示器的額定背光功耗值P_BL、開機預設亮度值U以及所述n個第一亮度調整比率S₁、S₂、...、S_n，計算與所述n個環境亮度分別對應的n個最大背光功耗值P_BLM1、P_BLM2、...、P_BLMn如下： P_BLMi=P_BL×U×S_i，其中i為1~n任一正整數。額定背光功耗值P_BL即是顯示器畫面亮度為最高亮度時的功耗，其為固定值，一般可由顯示器的規格書得知。 In step S13, the evaluation software calculates and performs according to the rated backlight power consumption value P _BL , the power-on preset brightness value U, and the n first brightness adjustment ratios S ₁ , S ₂ , . . . , S _{n of the} display. The n maximum backlight power consumption values P _BLM1 , P _BLM2 , . . . , P _BLMn corresponding to the n ambient luminances are as follows: P _BLMi =P _BL ×U×S _i , where i is any positive integer from 1 to n. The rated backlight power consumption value P _BL is the power consumption when the brightness of the display screen is the highest brightness. It is a fixed value and can generally be known from the specifications of the display.

在步驟S14，評估軟體根據所述n個最大背光功耗值P_BLM1、P_BLM2、...、P_BLMn、所述m個畫面數量N₁、N₂、...、N_m以及所述m個第二亮度調整比率D₁、D₂、...、D_m，計算與所述n個環境亮度分別對應的n個平均背光功耗值P_BLA1、P_BLA2、...、P_BLAn如下：其中i為1~n任一正整數。一般而言，環境亮度越高，顯示器畫面亮度需要越高，故最大背光功耗值需要越高。而在相同的環境亮度(即相同的最大背光功耗值)下，顯示器畫面內容的平均像素值越高，畫面整體而言較亮，故平均背光功耗值需要越高。簡單地說，環境亮度決定顯示器背光亮度或功耗之上限值，而顯示器畫面內容決定顯示器背光亮度或功耗之在該上限值內為多少。 In step S14, the evaluation software is based on the n maximum backlight power consumption values P _BLM1 , P _BLM2 , . . . , P _BLMn , the m number of pictures N ₁ , N ₂ , . . . , N _m and the m second brightness adjustment ratios D ₁ , D ₂ , . . . , D _m , calculating n average backlight power consumption values P _BLA1 , P _BLA2 , . . . , P _BLAn respectively corresponding to the n ambient brightnesses as follows: Where i is any positive integer from 1 to n. In general, the higher the ambient brightness, the higher the brightness of the display screen, so the maximum backlight power consumption value needs to be higher. In the same ambient brightness (ie, the same maximum backlight power consumption value), the higher the average pixel value of the display screen content, the brighter the overall picture, so the average backlight power consumption value needs to be higher. Briefly, ambient brightness determines the display backlight brightness or power consumption upper limit, and the display screen content determines how much of the display backlight brightness or power consumption is within the upper limit.

在步驟S15，評估軟體根據平均背光功耗值P_BLA1、P_BLA2、...、P_BLAn的平均值以及顯示器的額定主板功耗值P_MB，計算評估值P_{ON_E}如下：P_{ON_E}=(P_BLA1+P_BLA2+...+P_BLAn)/n+P_MB。額定主板功耗值P_MB即是顯示器例如包括主板、螢幕驅動板(Timing Controller，俗稱T-CON)、喇叭、USB等連接器等所有固定的功耗，一般可由顯示器的規格書得知。 In step S15, the evaluation software calculates the evaluation value P _{ON_E} according to the average value of the average backlight power consumption values P _BLA1 , P _BLA2 , . . . , P _BLAn and the rated main board power consumption value P _{MB of the} _display as follows: P _{ON_E} = (P _BLA1 + P _BLA2 +...+P _BLAn )/n+P _MB . The rated power consumption value of the motherboard is P _MB , which is the fixed power consumption of the display, such as the motherboard, the screen driver board (T-CON), the speaker, the USB, etc., and can be generally known by the specification of the display.

顯示器的能源效率測試方法還包括：在步驟S2，當評估軟體判斷評估值P_{ON_E}大於或等於閾值時，對開機預設亮度值U、所述n個第一亮度調整比率S₁、S₂、...、S_n及/或所述m個第二亮度調整比率D₁、D₂、...、D_m進行調整以使評估值P_{ON_E}小於閾值；以及在步驟S3，當評估值P_{ON_E}小於閾值時，實際量測以得到顯示器的開機模式平均功耗的量測值P_ON。步驟S2包括步驟S21~S22。 The energy efficiency test method of the display further includes: in step S2, when the evaluation software judgment evaluation value P _{ON_E is} greater than or equal to the threshold value, the power-on preset brightness value U, the n first brightness adjustment ratios S ₁ , S ₂ , ..., S _n and / or the m second brightness adjustment ratios D ₁ , D ₂ , ..., D _m are adjusted such that the evaluation value P _{ON_E is} smaller than the threshold; and in step S3, when the evaluation value P _{When ON_E is} less than the threshold, the actual measurement is taken to obtain the measured value P _{ON of the} average power consumption of the power-on mode of the display. Step S2 includes steps S21 to S22.

在步驟S21，評估軟體判斷評估值P_{ON_E}是否大於或等於閾值。當評估軟體判斷評估值P_{ON_E}大於或等於閾值時，執行步驟S22，對開機預設亮度值U、所述n個第一亮度調整比率S₁、S₂、...、S_n及/或所述m個第二亮度調整比率D₁、D₂、...、D_m進行調整，返回步驟S13以便重新執行步驟S13~S15得到減小的評估值P_{ON_E}。當評估軟體判斷評估值P_{ON_E}小於閾值時，執行步驟S3，實際量測以得到顯示器的開機模式平均功耗的量測值P_ON。 In step S21, it is evaluated whether the software judgment evaluation value P _{ON_E} is greater than or equal to the threshold. When evaluating the software determines the evaluation value _P ON_E greater than or equal to the threshold value, the step S22, the power-on preset brightness value U, the n first luminance adjustment ratio _{_{S 1, S 2, ...,}} S n and / or The m second brightness adjustment ratios D ₁ , D ₂ , ..., D _m are adjusted, and the process returns to step S13 to re-execute steps S13 to S15 to obtain a reduced evaluation value P _{ON_E} . When the evaluation software judgment evaluation value P _{ON_E is} smaller than the threshold value, step S3 is performed to actually measure the measurement value P _ON of the power-on mode average power consumption of the display.

顯示器的能源效率測試方法還包括：在步驟S4，當評估軟體判斷量測值P_ON大於顯示器的開機模式平均功耗的規範值P_{ON_MAX}(即最大可允許的開機模式平均功耗)時，對開機預設亮度值U、所述n個第一亮度調整比率S₁、S₂、...、S_n及/或所述m個第二亮度調整比率D₁、D₂、...、D_m進行調整以使量測值P_ON小於或等於規範值P_{ON_MAX}。步驟S4包括步驟S41~S42。 The energy efficiency test method of the display further includes: in step S4, when the evaluation software determination measurement value P _{ON is} greater than the specification value P _{ON_MAX of the} display mode average power consumption of the _display (ie, the maximum allowable power-on mode average power consumption), Turning on the preset brightness value U, the n first brightness adjustment ratios S ₁ , S ₂ , . . . , S _n and/or the m second brightness adjustment ratios D ₁ , D ₂ , . D _m is adjusted such that the measured value P _{ON is} less than or equal to the specification value P _{ON_MAX} . Step S4 includes steps S41 to S42.

在步驟S41，評估軟體判斷量測值P_ON是否大於規範值P_{ON_MAX}。當評估軟體判斷量測值P_ON大於規範值P_{ON_MAX}時，執行步驟S42，對開機預設亮度值U、所述n個第一亮度調整比率S₁、S₂、...、S_n及/或所述m個第二亮度調整比率D₁、D₂、...、D_m進行調整，返回步驟S13以便重新執行步驟S13~S15、S2與S3得到減小的量測值P_ON。當評估軟體判斷量測值P_ON小於或等於規範值P_{ON_MAX}時，結束測試流程。 In step S41, it is evaluated whether the software determination measurement value P _ON is larger than the specification value P _{ON_MAX} . When the evaluation software determination measurement value P _{ON is} greater than the specification value P _{ON_MAX} , step S42 is performed to switch on the preset brightness value U, the n first brightness adjustment ratios S ₁ , S ₂ , . . . , S _n and / or the m second brightness adjustment ratios D ₁ , D ₂ , ..., D _m are adjusted, and the process returns to step S13 to re-execute steps S13 to S15, S2 and S3 to obtain a reduced measurement value P _ON . When the evaluation software judgment measurement value P _{ON is} less than or equal to the specification value P _{ON_MAX} , the test flow is ended.

在設計上，閾值必然小於或等於規範值P_{ON_MAX}。當閾值與規範值P_{ON_MAX}的差距越大，表示評估值P_{ON_E}會規範值P_{ON_MAX}差距較大，如此一來，即使量測值P_ON會與評估值P_{ON_E}有些微出入，量測值P_ON仍會小於或等於規範值P_{ON_MAX}，因此可藉由採用與規範值P_{ON_MAX}有適當差距的閾值來避免執行步驟S42，即避免重新實際量測顯示器的量測值P_ON。 In design, the threshold must be less than or equal to the specification value P _{ON_MAX} . When the difference between the threshold and the normal value P _{ON_MAX} is larger, it means that the evaluation value P _{ON_E} has a larger difference between the normal value P _{ON_MAX} , and thus, even if the measured value P _ON is slightly different from the evaluation value P _{ON_E} , the measured value P _{The ON} will still be less than or equal to the specification value P _{ON — MAX} , so that step S42 can be avoided by using a threshold that is appropriately different from the canonical value P _{ON — MAX} , that is, to avoid actually measuring the measured value P _{ON of the} display.

下面以實際數值舉例說明圖1所示顯示器的能源效率測試方法中的部分步驟，但其僅是舉例而非用以限制本發明。 The following is a practical example of some of the steps in the energy efficiency test method of the display shown in FIG. 1, but it is merely an example and is not intended to limit the present invention.

在步驟S11，測試時間為10分鐘，測試視訊在10分鐘之測試時間內有616個畫面。各個畫面內的所有像素的像素值進行算數平均後可得到對應的平均像素值，而616個畫面的平均像素值可構成如圖2所示的平均像素值分布。圖2所示的平均像素值分布是將平均像素值0~100IRE等分成0~10IRE、10~20IRE、20~30IRE、...、90~100IRE而得到10個平均像素值區段，然後對616個畫面的平均像素值進行統計以得到分布於所述10個平均像素值區段的畫面數量N₁、N₂、...、N₁₀，N₁+N₂+...+N_m=616。在本例中，畫面數量N₁、N₂、...、N₁₀分別為2、7、65、149、176、129、60、18、7、3。換句話說，在616個畫面中，有2個畫面的平均像素值介於0~10IRE之間，有7個畫面的平均像素值介於10~20IRE之間，有65個畫面的平均像素值介於20~30IRE之間，有149個畫面的平均像素值介於30~40IRE之間等等。 In step S11, the test time is 10 minutes, and the test video has 616 pictures in the test time of 10 minutes. The pixel values of all the pixels in each picture are arithmetically averaged to obtain a corresponding average pixel value, and the average pixel value of 616 pictures may constitute an average pixel value distribution as shown in FIG. 2. The average pixel value distribution shown in FIG. 2 is obtained by dividing the average pixel value 0~100 IRE into 0~10 IRE, 10~20 IRE, 20~30 IRE, ..., 90~100 IRE to obtain 10 average pixel value segments, and then The average pixel values of the 616 pictures are counted to obtain the number of pictures N ₁ , N ₂ , . . . , N ₁₀ , N ₁ +N ₂ +...+N _m distributed over the 10 average pixel value segments. =616. In this example, the number of pictures N ₁ , N ₂ , ..., N ₁₀ are ₂ , ₇ , 65, 149, 176, 129, 60, ₁₈ , ₇ , 3, respectively. In other words, in 616 screens, the average pixel value of 2 screens is between 0 and 10 IRE, and the average pixel value of 7 screens is between 10 and 20 IRE, with an average pixel value of 65 screens. Between 20~30IRE, there are 149 screens with an average pixel value between 30~40IRE and so on.

The ambient brightness may include 3, 12, 35, and 100 lux, and the four first brightness adjustment ratios S ₁ , S ₂ , . . . , S ₄ respectively corresponding to the four ambient brightnesses may be respectively set to 40%, 50%, 60%, and 70%, indicating that after the automatic brightness control function is turned on, when the ambient light sensor senses an ambient brightness of, for example, 12 lux, the brightness of the picture is reduced to 50%. . The average pixel value segments may include 10 average pixel value segments (0~10 IRE, 10~20 IRE, 20~30 IRE, ..., 90~100 IRE) as shown in FIG. 2, and the 10 average pixels The 10 second brightness adjustment ratios D ₁ , D ₂ , . . . , D ₁₀ respectively corresponding to the value segments can be set to 50%, 60%, 70%, 80%, 90%, 100%, 100%, respectively. 100%, 100%, 100%, indicating that after the area dimming function is turned on, when the average pixel value of the played picture is, for example, 10~20 IRE (the picture is dark overall), the picture brightness is further reduced to 60%; when the average pixel value of the played picture is greater than 50 IRE (the whole picture is brighter), the picture brightness is adjusted to 100%, that is, no adjustment is made.

在步驟S13，計算出與環境亮度3、12、35、100勒克司分別對應的最大背光功耗值P_BLM1、P_BLM2、...、P_BLM4如下：P_BLM1=P_BL×U×S₁=P_BL×80%×40%、P_BLM2=P_BL×U×S₂=P_BL×80%×50%、P_BLM3=P_BL×U×S₃=P_BL×80%×60%、P_BLM4=P_BL×U×S₄=P_BL×80%×70%。 In step S13, the maximum backlight power consumption values P _BLM1 , P _BLM2 , . . . , P _BLM4 corresponding to the ambient luminances of 3, ₁₂ , ₃₅ , and 100 lux are respectively _calculated as follows: P _BLM1 =P _BL ×U×S ₁ =P _BL × 80% × 40%, P _BLM2 = P _BL × U × S ₂ = P _BL × 80% × 50%, P _BLM3 = P _BL × U × S ₃ = P _BL × 80% × 60%, P _BLM4 = P _BL × U × S ₄ = P _BL × 80% × 70%.

在步驟S14，計算出與環境亮度3、12、35、100勒克司分別對應的平均背光功耗值P_BLA1、P_BLA2、...、P_BLA4如下：P_BLA1=P_BLM1×[(N₁×D₁+N₂×D₂+...+N₁₀×D₁₀)/(N₁+N₂+...+N₁₀)]、P_BLA2=P_BLM2×[(N₁×D₁+N₂×D₂+...+N₁₀×D₁₀)/(N₁+N₂+...+N₁₀)]、P_BLA3=P_BLM3×[(N₁×D₁+N₂×D₂+...+N₁₀×D₁₀)/(N₁+N₂+...+N₁₀)]、P_BLA4=P_BLM4×[(N₁×D₁+N₂×D₂+...+N₁₀×D₁₀)/(N₁+N₂+...+N₁₀)]，其中，N₁×D₁+N₂×D₂+...+N₁₀×D₁₀=2×50%+7×60%+65×70%+149×80%+176×90%+129×100%+60×100%+18×100%+7×100%+3×100%，而N₁+N₂+...+N₁₀=k=616。 In step S14, the average backlight power consumption values P _BLA1 , P _BLA2 , . . . , P _BLA4 corresponding to the ambient luminances of 3, ₁₂ , ₃₅ , and _{100 lux} are _calculated as follows: P _BLA1 =P _BLM1 ×[(N ₁ ×D ₁ +N ₂ ×D ₂ +...+N ₁₀ ×D ₁₀ )/(N ₁ +N ₂ +...+N ₁₀ )], P _BLA2 =P _BLM2 ×[(N ₁ ×D ₁ +N ₂ ×D ₂ +...+N ₁₀ ×D ₁₀ )/(N ₁ +N ₂ +...+N ₁₀ )], P _BLA3 =P _BLM3 ×[(N ₁ ×D ₁ +N ₂ ×D ₂ +...+N ₁₀ ×D ₁₀ )/(N ₁ +N ₂ +...+N ₁₀ )], P _BLA4 =P _BLM4 ×[(N ₁ ×D ₁ +N ₂ ×D ₂ +...+N ₁₀ ×D ₁₀ )/(N ₁ +N ₂ +...+N ₁₀ )], where N ₁ ×D ₁ +N ₂ ×D ₂ +...+N ₁₀ ×D ₁₀ = 2 × 50% + 7 × 60% + 65 × 70% + 149 × 80% + 176 × 90% + 129 × 100% + 60 × 100% + 18 × 100% + 7 × 100% + 3 × 100 %, and N ₁ +N ₂ +...+N ₁₀ =k=616.

請同時參見圖1與圖3，圖3為圖1所示步驟S22(即對開機預設亮度值、該些第一亮度調整比率及/或該些第二亮度調整比率進行調整)之一實施例之流程圖。需要說明的是，執行步驟S22的前提是評估值(P_{ON_E})大於或等於閾值。在本實施例中，在圖1所示步驟S11一開始執行評估軟體時，評估軟體會進行參數等的初始化，此時會將p、q設為1；但並不限於此，實際上只要在圖1所示步驟S13之前將p、q設為1即可，例如可在執行完步驟S12後，將p、q設為1，然後才接著執行步驟S13。至於為何需要在步驟S13之前將p、q設為1，容後再敘。 Please refer to FIG. 1 and FIG. 3 at the same time. FIG. 3 is an implementation of step S22 shown in FIG. 1 (ie, adjusting the preset brightness value, the first brightness adjustment ratio, and/or the second brightness adjustment ratio). Flow chart of the example. It should be noted that the premise of performing step S22 is that the evaluation value (P _{ON_E} ) is greater than or equal to the threshold. In this embodiment, when the evaluation software is executed at the beginning of step S11 shown in FIG. 1, the evaluation software initializes parameters and the like, and p and q are set to 1 at this time; but it is not limited thereto, as long as it is P and q may be set to 1 before step S13 shown in FIG. 1. For example, after step S12 is executed, p and q may be set to 1, and then step S13 is performed. As for why it is necessary to set p and q to 1 before step S13.

在本實施例中，步驟S22包括步驟S221~S223，即是根據評估值與閾值相差的程度來決定調整哪些參數。開機預設亮度值U的調整對評估值的影響最大，所述n個第一亮度調整比率S₁、S₂、...、S_n的調整對評估值的影響次之，而所述m個第二亮度調整比率D₁、D₂、...、D_m的調整對評估值的影響最小。當評估值與閾值的差值大於閾值的第一百分比時，表示相差程度很大，故執行步驟S221對開機預設亮度值U進行調降，以便較快地使評估值變小。當評估值與閾值的差值小於或等於閾值的第一百分比且大於閾值的第二百分比時，表示相差程度中等，故執行步驟S222對所述n個第一亮度調整比率S₁、S₂、...、S_n進行調整。當評估值與閾值的差值小於或等於閾值的第二百分比時，表示相差程度很小，故執行步驟S223對所述m個第二亮度調整比率D₁、D₂、...、D_m進行調整。當執行完步驟S221、S222或S223時，即執行完步驟S22時，返回步驟S13以便通過步驟S13~S15計算出新的評估值，若新的評估值還是大於或等於閾值，則再一次執行步驟S22。在一實施例中，第一百分比為30%，第二百分比為10%，因此當所述差值大於閾值的30%時執行步驟S221，當所述差值小於或等於閾值的30%且大於閾值的10%時執行步驟S222，當所述差值小於或等於閾值的10%時執行步驟S223。 In this embodiment, step S22 includes steps S221 to S223, that is, which parameters are adjusted according to the degree to which the evaluation value differs from the threshold. The adjustment of the power-on preset brightness value U has the greatest influence on the evaluation value, and the adjustment of the n first brightness adjustment ratios S ₁ , S ₂ , . . . , S _n has the second influence on the evaluation value, and the m The adjustment of the second brightness adjustment ratios D ₁ , D ₂ , . . . , D _m has the least influence on the evaluation value. When the difference between the evaluation value and the threshold is greater than the first percentage of the threshold, indicating that the difference is large, step S221 is performed to adjust the power-on preset brightness value U to make the evaluation value smaller. When the difference between the evaluation value and the threshold is less than or equal to the first percentage of the threshold and greater than the second percentage of the threshold, indicating that the degree of phase difference is medium, step S222 is performed on the n first brightness adjustment ratios S ₁ , S ₂ , ..., S _n are adjusted. When the difference between the evaluation value and the threshold is less than or equal to the second percentage of the threshold, indicating that the degree of phase difference is small, performing step S223 on the m second brightness adjustment ratios D ₁ , D ₂ , . D _m is adjusted. When step S221, S222 or S223 is executed, that is, step S22 is executed, step S13 is returned to calculate a new evaluation value through steps S13 to S15, and if the new evaluation value is still greater than or equal to the threshold, the step is performed again. S22. In an embodiment, the first percentage is 30% and the second percentage is 10%, so step S221 is performed when the difference is greater than 30% of the threshold, when the difference is less than or equal to the threshold Step S222 is performed when 30% is greater than 10% of the threshold, and step S223 is performed when the difference is less than or equal to 10% of the threshold.

在本實施例中，步驟S221包括步驟S221_1~S221_2，步驟S222包括步驟S222_1~S222_5，步驟S223包括步驟S223_1~S223_4。在步驟S221_1，評估軟體判斷評估值與閾值的差值是否大於閾值的第一百分比，若是則執行步驟S221_2，若否則執行步驟S222_1。在步驟S221_2，表示評估值與閾值的差值大於閾值的第一百分比(例如所述差值大於閾值的30%)，此時以最小調整單位對開機預設亮度值U進行調降，然後返回步驟S13，其中開機預設亮度值U的最小調整單位例如是1%。在步驟S222_1，評估軟體判斷評估值與閾值的差值是否大於閾值的第二百分比，若是則執行步驟S222_2，若否則執行步驟S223_1。 In this embodiment, step S221 includes steps S221_1~S221_2, step S222 includes steps S222_1~S222_5, and step S223 includes steps S223_1~S223_4. In step S221_1, the evaluation software determines whether the difference between the evaluation value and the threshold is greater than a first percentage of the threshold. If yes, step S221_2 is performed, otherwise step S222_1 is performed. In step S221_2, it is indicated that the difference between the evaluation value and the threshold is greater than a first percentage of the threshold (for example, the difference is greater than 30% of the threshold), and at this time, the preset preset luminance value U is adjusted in a minimum adjustment unit, Then, the process returns to step S13, wherein the minimum adjustment unit of the power-on preset brightness value U is, for example, 1%. In step S222_1, the evaluation software determines whether the difference between the evaluation value and the threshold is greater than a second percentage of the threshold. If yes, step S222_2 is performed, otherwise step S223_1 is performed.

在步驟S222_2，表示評估值與閾值的差值小於或等於閾值的第一百分比且大於閾值的第二百分比(例如所述差值小於或等於閾值的30%且大於閾值的10%)，因此通過判斷p是否小於或等於n來判斷前次進行調整的第一亮度調整比率是否是S_n。若在步驟S222_2判斷p小於或等於n，則表示前次進行調整的第一亮度調整比率不是S_n，故執行步驟S222_3以最小調整單位對第一亮度調整比率S_p進行調降，然後執行步驟S222_4將p加1再返回步驟S13，其中第一亮度調整比率S_p的最小調整單位例如是10%。若在步驟S222_2判斷p大於n，則表示前次進行調整的第一亮度調整比率是S_n，故執行步驟S222_5將p設為1再執行步驟S222_3。 In step S222_2, indicating that the difference between the evaluation value and the threshold is less than or equal to a first percentage of the threshold and greater than a second percentage of the threshold (eg, the difference is less than or equal to 30% of the threshold and greater than 10% of the threshold) Therefore, it is judged whether or not the first brightness adjustment ratio that was previously adjusted is S _n by judging whether p is less than or equal to _n . If the determination in step S222_2 p is less than or equal to n, it said first luminance adjustment ratio is not adjusted previous S _n, so step S222_3 be lowered in the unit of the first luminance adjustment ratio S _p, and the step S222_4 plus 1 p-back step S13, the first in which the unit of the luminance adjustment ratio S _p of 10%, for example. If the determination in step S222_2 p is greater than n, it indicates that the ratio of the first luminance adjustment previous adjustment is S _n, so that the step S222_5 p 1 and then to step S222_3.

在步驟S223_1，表示評估值與閾值的差值小於或等於閾值的第二百分比(例如所述差值小於或等於閾值的10%)，通過判斷q是否小於或等於m來判斷前次進行調整的第二亮度調整比率是否是D_m。若在步驟S223_1判斷q小於或等於m，則表示前次進行調整的第二亮度調整比率不是D_m，故執行步驟S223_2以最小調整單位對第二亮度調整比率D_q進行調降，然後執行步驟S223_3將q加1再返回步驟S13，其中第二亮度調整比率D_q的最小調整單位例如是10%。若在步驟S223_1判斷q大於m，則表示前次進行調整的第二亮度調整比率是D_m，故執行步驟S223_4將q設為1再執行步驟S223_2。 In step S223_1, indicating that the difference between the evaluation value and the threshold is less than or equal to a second percentage of the threshold (for example, the difference is less than or equal to 10% of the threshold), and determining whether the previous time is performed by determining whether q is less than or equal to m Whether the adjusted second brightness adjustment ratio is D _m . If it is determined in step S223_1 that q is less than or equal to m, it indicates that the second brightness adjustment ratio that was previously adjusted is not D _m , so step S223_2 is performed to adjust the second brightness adjustment ratio D _q in a minimum adjustment unit, and then steps are performed. S223_3 q plus the back 1 step S13, the second adjustment unit, wherein the minimum ratio of the luminance adjustment, for example, D 10% _q. If it is determined in step S223_1 that q is greater than m, it means that the second brightness adjustment ratio that was previously adjusted is D _m , so step S223_4 is executed to set q to 1 and then step S223_2 is performed.

需要說明的是，通過步驟S221_1與S222_1，每次執行步驟S22，只會執行步驟S221~S223其中之一。通過步驟S222_2~S222_5，每次執行步驟S222，只會以最小調整單位對某個第一亮度調整比率S_p進行調降，且因為在步驟S13之前與步驟S222_5中將p設為1而會按照S₁、S₂、...、S_n、S₁、S₂、...、S_n、S₁、S₂、...的順序進行調整，如此可保持S₁≦S₂≦...≦S_n。通過步驟S223_1~S223_4，每次執行步驟S223，只會以最小調整單位對某個第二亮度調整比率D_q進行調降，且因為在步驟S13之前與步驟S223_4中將q設為1而會按照D₁、 D₂、...、D_m、D₁、D₂、...、D_m、D₁、D₂、...的順序進行調整，如此可保持D₁≦D₂≦...≦D_m。藉此，通過反覆執行圖1所示步驟S13、S14、S15、S21與圖3所示S22以及最小調整單位，評估軟體可自動地對開機預設亮度值、該些第一亮度調整比率及/或該些第二亮度調整比率進行調整，以使評估值小於閾值。 It should be noted that, by step S221_1 and S222_1, only one of steps S221 to S223 is performed each time step S22 is executed. , Each execution of step S222, the minimum will be lowered to an adjustment unit adjusting a first luminance ratio S _p by step S222_2 ~ S222_5, and as in step S13 is set to p S222_5 prior to step 1 but will in accordance with The order of S ₁ , S ₂ , ..., S _n , S ₁ , S ₂ , ..., S _n , S ₁ , S ₂ , ... is adjusted so that S ₁ ≦S ₂ ≦ can be maintained. ..≦S _n . , Each execution of step S223, the minimum will be cut adjustment unit for adjusting a second luminance ratio D _q step S223_1 ~ S223_4, and as in step S13 and is set to 1 in step S223_4 q will follow before the The order of D ₁ , D ₂ , ..., D _m , D ₁ , D ₂ , ..., D _m , D ₁ , D ₂ , ... is adjusted so that D ₁ ≦ D ₂ ≦ can be maintained. ..≦D _m . Thereby, by repeatedly performing steps S13, S14, S15, and S21 shown in FIG. 1 and S22 and the minimum adjustment unit shown in FIG. 3, the evaluation software can automatically preset the brightness values for the power-on, the first brightness adjustment ratios, and/or Or the second brightness adjustment ratios are adjusted such that the evaluation value is less than the threshold.
