Taking a flexible display panel as an example, please refer to FIG. 1b, the display panel 100 is folded along a folding line 106, so the display panel 100 is divided into a display area 107 and a non-display area 108, and all corresponding pixel units located in the display area 107 are Lights up, and all corresponding pixel units located in the non-display area 108 are turned off.
当显示面板100沿着折叠线106折叠了多次后，由于不同折叠区域的亮暗次数不同，OLED材料随着发光次数的增加，发光性能逐渐下降。因此，当需要展开显示时，先前不同折叠区域的显示亮度会存在差异的。请参阅图1c，用户总共对显示面板折叠80次，其中，在折叠后的历史点亮次数中，第一屏幕区域1c1被点亮的次数为30次，第二屏幕区域1c2被点亮的次数为50次。在展开显示时，第一屏幕区域1c1比较亮，第二屏幕区域1c2比较暗。出于不同角度地观察，在一些实施例中，第一屏幕区域1c1可被称为亮度异常区域，第二屏幕区域1c2可被称为亮度正常区域。在另一些实施例中，第一屏幕区域1c1可被称为亮度正常区域，第二屏幕区域1c2可被称为亮度异常区域。When the display panel 100 is folded multiple times along the folding line 106, the light-emitting performance of the OLED material gradually decreases as the number of light-emitting times increases due to different light-dark times of different folding regions. Therefore, when it is necessary to expand the display, the display brightness of the different folding areas will be different. Referring to FIG. 1c, the user folds the display panel a total of 80 times. Among the number of historical lighting times after folding, the first screen area 1c1 is lit 30 times and the second screen area 1c2 is lit For 50 times. During the unfolding display, the first screen area 1c1 is relatively bright, and the second screen area 1c2 is relatively dark. Viewed from different angles, in some embodiments, the first screen area 1c1 may be referred to as an abnormal brightness area, and the second screen area 1c2 may be referred to as a normal brightness area. In other embodiments, the first screen area 1c1 may be referred to as a normal brightness area, and the second screen area 1c2 may be referred to as an abnormal brightness area.
在本申请实施例中，通过亮度调节，其能够将第一屏幕区域1c1与第二屏幕区域1c2的亮度调节一致，使得第一屏幕区域1c1与第二屏幕区域1c2之间的亮度分界线得以消失，使得各个屏幕区域的亮度均匀显示。In the embodiment of the present application, by adjusting the brightness, it can adjust the brightness of the first screen area 1c1 and the second screen area 1c2 to be consistent, so that the brightness boundary between the first screen area 1c1 and the second screen area 1c2 can disappear , So that the brightness of each screen area is displayed uniformly.
作为本申请实施例的一方面，本申请实施例提供一种屏幕显示方法。请参阅图2a，屏幕显示方法200包括：As an aspect of the embodiments of the present application, the embodiments of the present application provide a screen display method. Referring to FIG. 2a, the screen display method 200 includes:
S21、确定屏幕的亮度异常区域；S21. Determine the abnormal brightness area of the screen;
在本实施例中，屏幕使用柔性基板或刚性基板，柔性基板诸如包括薄玻璃、金属箔片或塑料基底等等具有柔性的材料，例如，塑料基底具有包括涂覆在基膜的两侧上的柔性结构，基膜包括诸如聚酰亚胺(PI)、聚碳酸酯(PC)、聚乙二醇对酞酸酯(PET)、聚醚砜(PES)、聚乙烯薄膜(PEN)、纤维增强塑料(FRP)等等树脂。刚性基板可以为，但不局限于玻璃基板、金属基板、或陶瓷基板。In the present embodiment, the screen uses a flexible substrate or a rigid substrate, such as a flexible substrate including thin glass, metal foil, or a plastic substrate, etc., having a flexible material, for example, the plastic substrate has a substrate coated on both sides of the base film Flexible structure, the base film includes such as polyimide (PI), polycarbonate (PC), polyethylene glycol terephthalate (PET), polyethersulfone (PES), polyethylene film (PEN), fiber reinforced Plastic (FRP) and other resins. The rigid substrate may be, but not limited to, a glass substrate, a metal substrate, or a ceramic substrate.
在本实施例中，折叠时，以折叠线为分界线，屏幕被分为至少两个屏幕区域，其中，一个屏幕区域中各行像素单元按照第一方向被点亮，另一个屏幕区域中各行像素单元未被点亮。其中，该折叠线可在形成屏幕时已被构造及预设，亦可以由用户折叠屏幕而形成的。In this embodiment, when folding, the screen is divided into at least two screen areas using the folding line as the dividing line, where each row of pixel units in one screen area is lit according to the first direction and each row of pixels in the other screen area The unit is not illuminated. The folding line may have been constructed and preset when the screen is formed, or may be formed by the user folding the screen.
在本实施例中，第一方向可由用户自定义，例如，以屏幕所在的平面建立坐标系XOY，第一方向可以为自X正半轴到X负半轴的方向，可以为自X负半轴到X正半轴的方向，可以为自Y正半轴到Y负半轴的方向，可以为自Y负半轴到Y正半轴的方向。In this embodiment, the first direction can be defined by the user. For example, the coordinate system XOY is established based on the plane where the screen is located. The first direction can be the direction from the positive X axis to the negative X axis, which can be from X negative half The direction from the axis to the positive X axis can be the direction from the positive Y axis to the negative Y axis, and can be the direction from the negative Y axis to the positive Y axis.
屏幕的亮度异常区域的产生因素可多种，例如，如前所述，屏幕经过多次折叠后，由于不同屏幕区域在历史点亮次数上存在不同，导致不同屏幕区域在展开显示时，存在亮度显示不均匀的现象，亦即，亮度过亮的屏幕区域可为亮度异常区域，或者，亮度过暗的屏幕区域可为亮度异常区域。There are many factors that can cause the abnormal brightness area of the screen. For example, as mentioned above, after the screen is folded multiple times, different screen areas have different historical lighting times. The phenomenon of uneven display, that is, the screen area with excessive brightness may be an abnormal brightness area, or the screen area with excessively dark brightness may be an abnormal brightness area.
再例如，虽然各个屏幕区域的历史点亮次数相同，但是屏幕受制作工艺的影响，不同屏幕区域的亮度也会出现不均匀的情况，亦即，不同屏幕区域的亮度之间存在差异化，在此种情况下，亮度过亮的屏幕区域可为亮度异常区域，或者，亮度过暗的屏幕区域可为亮度异常区域。As another example, although the historical lighting times of each screen area are the same, the screen is affected by the production process, and the brightness of different screen areas may also be uneven, that is, there is a difference between the brightness of different screen areas. In this case, the screen area that is too bright may be an abnormal brightness area, or the screen area that is too dark may be an abnormal brightness area.
S22、获取亮度异常区域被点亮的起始时间；S22. Obtain the starting time when the area with abnormal brightness is lit;
在本实施例中，由于驱动电路按照一定方向依序扫描各行像素单元，由此而点亮各行像素单元，因此，屏幕的不同屏幕区域被点亮的起 始时间是不同的，起始时间为每个屏幕区域中首先被点亮的首行像素单元的点亮时间。例如，屏幕排列有150行像素单元，在显示一帧画面下，每行像素单元的扫描时间为0.2ms，当屏幕不存在亮度异常区域时，该屏幕被点亮的起始时间为第一行像素单元的起始时间，亦即为第0ms。当屏幕存在亮度异常区域与亮度正常区域，其中，亮度正常区域为第1行至第50行的像素单元，亮度异常区域为第51行至第150行的像素单元，因此，亮度正常区域被点亮的起始时间为第0ms，亮度异常区域被点亮的起始时间为第10ms。In this embodiment, since the driving circuit sequentially scans the pixel units of each row according to a certain direction, thereby lighting the pixel units of each row, the start time of different screen areas of the screen being lit is different, and the start time is The lighting time of the first row of pixel cells that are lit first in each screen area. For example, the screen is arranged with 150 rows of pixel units. When displaying a frame of pictures, the scanning time of each row of pixel units is 0.2ms. When there is no abnormal brightness area on the screen, the start time for the screen to be lit is the first row The starting time of the pixel unit is the 0ms. When there is an abnormal brightness area and a normal brightness area on the screen, the normal brightness area is the pixel unit of the 1st line to the 50th line, and the abnormal brightness area is the pixel unit of the 51st line to the 150th line, therefore, the normal brightness area is marked The start time of lighting is 0ms, and the start time of the area with abnormal brightness is 10ms.
S23、根据起始时间，调节亮度异常区域的亮度。S23. Adjust the brightness of the abnormal brightness area according to the starting time.
在本实施例中，屏幕自亮度异常区域的起始时间开始，便开始调节亮度异常区域的亮度，举例而言，调节亮度异常区域的亮度与亮度正常区域的亮度相同，例如，将亮度过亮的屏幕区域的亮度调低，直至该屏幕区域与其它屏幕区域的亮度相一致，或者，将亮度过暗的屏幕区域的亮度调高，直至该屏幕区域与其它屏幕区域的亮度相一致。In this embodiment, the screen starts to adjust the brightness of the abnormal brightness area from the start time of the abnormal brightness area. For example, adjusting the brightness of the abnormal brightness area is the same as the brightness of the normal brightness area, for example, the brightness is too bright The brightness of the screen area of is lowered until the brightness of the screen area is consistent with that of other screen areas, or the brightness of the screen area that is too dark is increased until the brightness of the screen area is consistent with the brightness of other screen areas.
再举例而言，调节亮度异常区域的亮度与亮度正常区域的亮度之间的差值落入预设阈值范围内。For another example, the difference between the brightness of the abnormal brightness adjustment area and the brightness of the normal brightness area falls within a preset threshold range.
在本实施例中，通过补偿亮度异常区域的亮度，从而提高显示效果以及画质品质。In this embodiment, the brightness of the abnormal brightness area is compensated to improve the display effect and image quality.
在一些实施例中，确定屏幕的亮度异常区域的方式比较多，例如，通过获取在指定灰阶下屏幕对应的显示画面，通过图像分析算法分析该显示画面，从中确定屏幕的亮度异常区域。再例如，其还可以通过统计屏幕中各个屏幕区域对应的历史点亮时间以确定亮度异常区域。请参阅图2b，S21包括：In some embodiments, there are many ways to determine the abnormal brightness area of the screen. For example, by acquiring the display image corresponding to the screen at the specified gray scale, the display image is analyzed by an image analysis algorithm to determine the abnormal brightness area of the screen. For another example, it can also determine the area with abnormal brightness by counting the historical lighting time corresponding to each screen area in the screen. Please refer to Figure 2b, S21 includes:
S211、获取屏幕中各个屏幕区域对应的历史点亮时间；S211: Obtain the historical lighting time corresponding to each screen area in the screen;
S212、选择满足预设条件的历史点亮时间对应的屏幕区域作为亮度异常区域。S212. Select the screen area corresponding to the historical lighting time that meets the preset condition as the abnormal brightness area.
在本实施例中，历史点亮时间为在历史使用屏幕过程中，各个屏幕区域被点亮的总时间，例如，第一屏幕区域A的历史点亮时间为2400个小时，第二屏幕区域B的历史点亮时间为2000个小时。In this embodiment, the historical lighting time is the total time that each screen area is lit during the history of using the screen. For example, the historical lighting time of the first screen area A is 2400 hours, and the second screen area B The historical lighting time is 2000 hours.
对于屏幕被预设有固定折叠线的情况下，每次折叠后，屏幕皆记录并累加不同屏幕区域的点亮时间，从而得到各个屏幕区域对应的历史点亮时间。For the case where the screen is preset with a fixed folding line, after each folding, the screen records and accumulates the lighting time of different screen areas, thereby obtaining the historical lighting time corresponding to each screen area.
在一些实施例中，请参阅图2c，屏幕的背面设置有若干弯曲传感器2c1，弯曲传感器2c1用于检测屏幕的折叠度以及折叠位置，其中，弯曲传感器可以根据业务需求，沿着预设方向部分地或者全面地布设于屏幕上，因此，弯曲传感器能够部分地或者全面地检测到屏幕的弯曲区域位置、弯曲半径、弯曲角度等等。举例而言，在纵向上，各个弯曲传感器2c1分别沿着Y轴依次排列。在横向上，各个弯曲传感器2c1分别沿着X轴依次排列，其中，每个弯曲传感器2c1有规律地间隔预设距离进行排列。In some embodiments, please refer to FIG. 2c, a plurality of bending sensors 2c1 are provided on the back of the screen, and the bending sensors 2c1 are used to detect the folding degree and folding position of the screen, wherein the bending sensors can be partially along the preset direction according to business requirements It is arranged on the screen completely or completely, so the bending sensor can partially or fully detect the position of the bending area, the bending radius, the bending angle, etc. of the screen. For example, in the longitudinal direction, the respective bending sensors 2c1 are sequentially arranged along the Y axis. In the lateral direction, the respective bending sensors 2c1 are sequentially arranged along the X axis, wherein each bending sensor 2c1 is regularly arranged at a predetermined distance.
当外力向屏幕施加压力而使屏幕弯曲时，其可以根据压力变化的传感器所处的位置而识别出弯曲区域。每个弯曲传感器2c1可以是电阻传感器或者微光纤传感器。在一些实施例中，弯曲传感器2c1还可以为加速度传感器、重力传感器、陀螺仪等等。When an external force exerts pressure on the screen to bend the screen, it can identify the bending area according to the position of the pressure change sensor. Each bending sensor 2c1 may be a resistance sensor or a micro-fiber sensor. In some embodiments, the bending sensor 2c1 may also be an acceleration sensor, a gravity sensor, a gyroscope, and so on.
对于屏幕未被预设有规定折叠线，并且由用户自由折叠屏幕的情况下，屏幕通过弯曲传感器检测出的弯曲区域位置，从而得知折叠线所在的位置，进而得知能够显示画面的屏幕区域以及未能够显示画面的屏幕区域，再进而统计出各个屏幕区域对应的历史点亮时间。For the case where the screen is not preset with a prescribed folding line, and the user freely folds the screen, the screen detects the position of the bending area by the bending sensor, so as to know the position of the folding line, and then know the screen area that can display the screen And the screen area where the screen cannot be displayed, and then the historical lighting time corresponding to each screen area is counted.
在本实施例中，预设条件由用户根据业务需求自定义，例如，预设条件为预设点亮时间阈值范围，满足预设条件为历史点亮时间落入预设点亮时间阈值范围，未满足预设条件为历史点亮时间未落入预设点亮时间阈值范围。In this embodiment, the preset condition is customized by the user according to business needs. For example, the preset condition is a preset lighting time threshold range, and the meeting of the preset condition is that the historical lighting time falls within the preset lighting time threshold range, The failure to meet the preset condition is that the historical lighting time does not fall within the preset lighting time threshold range.
如前所述，随着点亮时间越长，OLED材料的发光效率越低。随着点亮时间越短，OLED材料的发光效率不容易下降。在一些实施例中，请参阅图2d，S212包括：As mentioned above, the longer the lighting time, the lower the luminous efficiency of the OLED material. As the lighting time is shorter, the luminous efficiency of the OLED material is not easy to drop. In some embodiments, referring to FIG. 2d, S212 includes:
S2121、比较任意两个屏幕区域对应的历史点亮时间；S2121. Compare the historical lighting time corresponding to any two screen areas;
S2122、根据比较结果，遍历出历史点亮时间为最长或最短的屏幕区域作为亮度异常区域。S2122. According to the comparison result, the screen area with the longest or shortest lighting time in history is traversed as the abnormal brightness area.
在本实施例中，当屏幕被折叠成至少两个屏幕区域时，屏幕可通过比较任意两个屏幕区域对应的历史点亮时间，以此遍历出亮度异常区域。例如，屏幕区域A1对应的历史点亮时间t1为1500个小时，屏幕区域A2对应的历史点亮时间t2为1600个小时，屏幕区域A3对应的历史点亮时间t3为2000个小时，屏幕区域A4对应的历史点亮时间t4为2400个小时，通过比较，历史点亮时间由长到短的顺序为：t4>t3>t2>t1，因此，展开显示时，屏幕区域A4的亮度比较暗，屏幕区域A1的亮度比较亮，因此，可以选择屏幕区域A4作为亮度异常区域，亦可以选择屏幕区域A1作为亮度异常区域。In this embodiment, when the screen is folded into at least two screen areas, the screen can traverse the abnormal brightness area by comparing the historical lighting times corresponding to any two screen areas. For example, the historical lighting time t1 corresponding to the screen area A1 is 1500 hours, the historical lighting time t2 corresponding to the screen area A2 is 1600 hours, the historical lighting time t3 corresponding to the screen area A3 is 2000 hours, and the screen area A4 The corresponding historical lighting time t4 is 2400 hours. By comparison, the order of historical lighting time from long to short is: t4>t3>t2>t1. Therefore, when the display is expanded, the brightness of the screen area A4 is relatively dark, the screen The brightness of the area A1 is relatively bright. Therefore, the screen area A4 can be selected as the brightness abnormal area, and the screen area A1 can also be selected as the brightness abnormal area.
在一些实施例中，显示时，按照第一方向依序点亮屏幕中各行像素单元。因此，在获取亮度异常区域被点亮的起始时间的过程中，屏幕选择亮度异常区域中首先被点亮的首行像素单元对应的点亮时间作为起始时间。如前所述，屏幕排列有150行像素单元，其中，亮度异常区域为第51行至第150行的像素单元，则第51行像素单元为亮度异常区域中首行像素单元，并且，在展开显示时，第51行像素单元在亮度异常区域中首先被点亮的，则，第51行像素单元被点亮的点亮时间作为起始时间。In some embodiments, during display, the pixel units of each row in the screen are sequentially lit according to the first direction. Therefore, in the process of acquiring the starting time when the abnormal brightness area is lit, the screen selects the lighting time corresponding to the first row of pixel units in the abnormal brightness area as the starting time. As mentioned earlier, the screen is lined with 150 rows of pixel units, where the area with abnormal brightness is the pixel unit from line 51 to line 150, then the line 51 pixel unit is the first line of pixel units in the area with abnormal brightness, and When displaying, the pixel unit of the 51st row is first lit in the region of abnormal brightness, then the lighting time when the pixel unit of the 51st row is lit is taken as the start time.
在一些实施例中，选择亮度异常区域中首先被点亮的首行像素单元对应的点亮时间作为起始时间的过程中，首先，屏幕确定亮度异常区域中首先被点亮的首行像素单元对应的目标行数，例如，第51行作为目标行数。In some embodiments, in the process of selecting the lighting time corresponding to the first-line pixel unit in the abnormal brightness area as the starting time, first, the screen determines the first-line pixel unit in the abnormal brightness area that is first lit Corresponding target line number, for example, the 51st line is the target line number.
其次，屏幕根据目标行数与预设扫描时间，计算出切换时间，例如，预设扫描时间为每行0.2ms，计算出驱动电路打开各行像素单元的数量，因此，第51行像素单元的切换时间为0.2*(51-1)＝10ms。Secondly, the screen calculates the switching time based on the target number of lines and the preset scan time. For example, the preset scan time is 0.2 ms per line, and the number of pixel units in each line that the drive circuit turns on is calculated. Therefore, the switching of the pixel unit in line 51 The time is 0.2*(51-1)=10ms.
最后，屏幕将切换时间作为起始时间。Finally, the screen will use the switching time as the starting time.
在一些实施例中，调节亮度屏幕区域的亮度的方式多种多样，屏幕自动检测出亮度屏幕区域，自动调节亮度异常区域的亮度。或者，屏幕根据亮度调节指令实施亮度异常区域的亮度调节。请参阅图3a，S23包括：In some embodiments, there are various ways to adjust the brightness of the brightness screen area. The screen automatically detects the brightness screen area and automatically adjusts the brightness of the abnormal brightness area. Or, the screen adjusts the brightness of the abnormal brightness area according to the brightness adjustment instruction. Referring to Figure 3a, S23 includes:
S231、在显示灰阶下，获取亮度调节指令；S231. Obtain the brightness adjustment instruction in the display gray scale;
S232、自起始时间开始，根据亮度调节指令，调节亮度异常区域的亮度至预设亮度。S232. From the start time, adjust the brightness of the area with abnormal brightness to the preset brightness according to the brightness adjustment instruction.
显示一帧画面时，向屏幕输入显示灰阶，通过伽马校正后，使得屏幕显示对应的亮度。因此，显示灰阶为展开显示时，屏幕显示该帧画面所对应的灰阶。未输入屏幕并辅助显示当前显示画面之用的灰阶作为中间灰阶或者未显示灰阶。可以理解的是，当未显示灰阶输入屏幕以使得屏幕显示一帧画面时，该未显示灰阶变成了“显示灰阶”，因此“未显示灰阶”与“显示灰阶”在输入屏幕作为显示之用是而被互相转化，并不是固定地作为“未显示灰阶”与“显示灰阶”。When displaying a frame of pictures, input the display gray scale to the screen, and after gamma correction, make the screen display the corresponding brightness. Therefore, when the display gray scale is the expanded display, the screen displays the gray scale corresponding to the frame. The gray scale used for not displaying the screen and assisting in displaying the currently displayed picture is used as the intermediate gray scale or the gray scale is not displayed. It can be understood that when the gray scale input screen is not displayed so that the screen displays a frame of pictures, the undisplayed gray scale becomes "display gray scale", so "non-display gray scale" and "display gray scale" are input The screen is used for display and is converted into each other, and is not fixedly used as "non-display gray scale" and "display gray scale".
如前所述，屏幕支持任何位数的灰阶显示，例如，支持全灰阶为0-255灰阶，当灰阶250输入屏幕以使得屏幕显示一帧画面时，灰阶250作为显示灰阶，然而，诸如灰阶0至249或者251至255等等作为未显示灰阶。As mentioned earlier, the screen supports grayscale display of any number of digits. For example, it supports full grayscale of 0-255 grayscale. When grayscale 250 is input to the screen so that the screen displays a frame of pictures, grayscale 250 is used as the display grayscale. However, such gray levels as 0 to 249 or 251 to 255, etc. are not displayed as gray levels.
亮度调节指令的获取方式多种多样，举例而言，用户可操作屏幕的物理按键而触发亮度调节指令，例如，用户连续按动屏幕的POWER键三次，便可以进入亮度异常区域的亮度调节模式，再按动一次，便可以按照预设亮度调节比例调节亮度异常区域的亮度。There are various ways to obtain the brightness adjustment command. For example, the user can operate the physical buttons on the screen to trigger the brightness adjustment command. For example, the user can press the POWER button on the screen three times in succession to enter the brightness adjustment mode of the abnormal brightness area. Press again to adjust the brightness of the abnormal brightness area according to the preset brightness adjustment ratio.
再举例而言，屏幕显示有亮度调试界面，亮度调试界面包括若干个亮度虚拟调节器，亮度调节指令由用户操作亮度虚拟调节器而触发屏幕将亮度比例系数封装于指令而分发出的，于是，屏幕便可以根据亮度调节指令调节亮度异常区域的亮度。For another example, the screen displays a brightness debugging interface. The brightness debugging interface includes several brightness virtual adjusters. The brightness adjustment command is issued by the user operating the brightness virtual adjuster to trigger the screen to encapsulate the brightness scale factor in the command and issue. So, The screen can adjust the brightness of the abnormal brightness area according to the brightness adjustment instruction.
在一些实施例中，亮度调节指令包括亮度比例系数。请参阅图3b，S232包括：In some embodiments, the brightness adjustment instruction includes a brightness scale factor. Referring to Figure 3b, S232 includes:
S2321、根据亮度比例系数与预设伽马曲线，调节亮度异常区域的亮度至预设亮度；S2321: Adjust the brightness of the abnormal brightness area to the preset brightness according to the brightness scale factor and the preset gamma curve;
S2322、记录不同显示灰阶对应的预设亮度；S2322. Record the preset brightness corresponding to different display gray levels;
S2323、计算出不同未显示灰阶对应的预设亮度；S2323. Calculate the preset brightness corresponding to different undisplayed gray levels;
S2324、记录各个未显示灰阶对应的预设亮度。S2324. Record the preset brightness corresponding to each gray level not displayed.
在本实施例中，亮度比例系数由用户自定义设置，例如，亮度比例系数对应的亮度调节范围为0至100％，其中，屏幕中的亮度调试界面显示有4组亮度虚拟调节器，每个亮度虚拟调节器对应的亮度调节范围皆为0至100％。请参阅图3c，调节时，用户选择在显示灰阶为255时，对亮度异常区域作调节，例如，用户操作第一组亮度调节虚拟调节器K1，输出的亮度比例系数为10％。用户选择在显示灰阶为250时，对亮度异常区域作调节，用户操作第二组亮度调节虚拟调节器K2，输出的亮度比例系数为5％。用户选择在显示灰阶为128时，对亮度异常区域作调节，用户操作第三组亮度调节虚拟调节器K3，输出的亮度比例系数为8％。用户选择在显示灰阶为32时，对亮度异常区域作调节，用户操作第四组亮度调节虚拟调节器K4，输出的亮度比例系数为6％。In this embodiment, the brightness scale factor is set by the user. For example, the brightness scale range corresponds to a brightness adjustment range of 0 to 100%. Among them, the brightness debug interface on the screen displays 4 sets of brightness virtual adjusters, each The brightness adjustment range corresponding to the brightness virtual regulator is 0 to 100%. Please refer to FIG. 3c. During the adjustment, the user chooses to adjust the abnormal brightness area when the display gray level is 255. For example, when the user operates the first group of brightness adjustment virtual adjusters K1, the output brightness scale factor is 10%. The user chooses to adjust the abnormal brightness area when the display gray level is 250. The user operates the second group of brightness adjustment virtual adjusters K2, and the output brightness scale factor is 5%. The user chooses to adjust the abnormal brightness area when the display gray level is 128. The user operates the third group of brightness adjustment virtual adjusters K3, and the output brightness scale factor is 8%. The user chooses to adjust the abnormal brightness area when the display gray level is 32. The user operates the fourth group of brightness adjustment virtual adjusters K4, and the output brightness scale factor is 6%.
预设伽马曲线由用户根据业务需求自行选择，例如，预设伽马曲线对应的函数为：The preset gamma curve is selected by the user according to business needs. For example, the function corresponding to the preset gamma curve is:
Figure PCTCN2019070063-appb-000001
Figure PCTCN2019070063-appb-000001
其中，x为预设灰阶的灰阶数，L x为第x灰阶的目标亮度，L 255为第255灰阶的目标亮度，γ为伽马值。 Where x is the number of gray levels of the preset gray level, L x is the target brightness of the xth gray level, L 255 is the target brightness of the 255th gray level, and γ is the gamma value.
一般的，用户根据预设伽马曲线，计算出不同灰阶对应的目标亮度，并根据不同灰阶与目标亮度的对应关系，构建gamma校正表，通过查找gamma校正表，可以知悉任意灰阶对应的目标亮度值。Generally, the user calculates the target brightness corresponding to different gray levels according to the preset gamma curve, and constructs the gamma correction table according to the corresponding relationship between the different gray levels and the target brightness. By looking up the gamma correction table, you can know the correspondence of any gray level The target brightness value.
在本实施例中，亮度比例系数作为k，其可与L x相乘或者作任何合适的运算，于是，其便可以计算出在显示灰阶下对应修正后的目标亮度。例如，修正后的伽马曲线对应的函数为： In this embodiment, the brightness scale factor is k, which can be multiplied by L x or any suitable calculation, so that it can calculate the corresponding corrected target brightness in the display gray scale. For example, the function corresponding to the modified gamma curve is:
Figure PCTCN2019070063-appb-000002
Figure PCTCN2019070063-appb-000002
其中，L” x为修正后的目标亮度。 Among them, L″ x is the corrected target brightness.
因此，屏幕便可以根据式二，调节亮度异常区域的亮度至预设亮度，亦即，预设亮度为修正后的目标亮度。例如，当显示灰阶为255时，k为10％，预设亮度(修正后的目标亮度)为350nit。当显示灰阶为250时，k为5％，预设亮度为330nit。当显示灰阶为128时，k为10％，预设亮度为160nit。Therefore, the screen can adjust the brightness of the abnormal brightness area to the preset brightness according to Equation 2, that is, the preset brightness is the corrected target brightness. For example, when the display gray scale is 255, k is 10%, and the preset brightness (corrected target brightness) is 350nit. When the display gray level is 250, k is 5%, and the preset brightness is 330nit. When the display gray level is 128, k is 10%, and the preset brightness is 160nit.
在上述预设亮度下，屏幕可以消除不同显示灰阶下的亮度异常区域与亮度正常区域之间的分界线，使得屏幕的各个屏幕区域的显示亮度均匀。Under the above preset brightness, the screen can eliminate the boundary between the abnormal brightness area and the normal brightness area in different display gray levels, so that the display brightness of each screen area of the screen is uniform.
为了可靠快速地实现另一帧画面的亮度异常区域的亮度调节，屏幕记录不同显示灰阶对应的预设亮度，例如记录显示灰阶为255、250、128各自对应的预设亮度。In order to reliably and quickly adjust the brightness of the abnormal brightness area of another frame, the screen records the preset brightness corresponding to different display gray levels, for example, the preset brightness corresponding to the display gray levels of 255, 250, and 128 respectively.
为了实现全灰阶下对亮度异常区域的亮度调节，屏幕还计算出不同未显示灰阶对应的预设亮度。在一些实施例中，计算出不同未显示灰阶对应的预设亮度的方式多种多样，例如，请参阅图3c，S2323包括：In order to realize the brightness adjustment of the abnormal brightness area under the full gray scale, the screen also calculates the preset brightness corresponding to different undisplayed gray scales. In some embodiments, there are various ways to calculate the preset brightness corresponding to different undisplayed gray levels. For example, referring to FIG. 3c, S2323 includes:
S31、确定至少两组显示灰阶对应的预设亮度；S31. Determine a preset brightness corresponding to at least two groups of display gray levels;
S32、根据插值法与至少两组显示灰阶对应的预设亮度，计算出插值函数；S32. Calculate the interpolation function according to the preset brightness corresponding to the at least two sets of display gray levels by the interpolation method;
S33、根据插值函数与每个未显示灰阶，计算出各个未显示灰阶对应的预设亮度。S33. Calculate the preset brightness corresponding to each undisplayed gray scale according to the interpolation function and each undisplayed gray scale.
在本实施例中，首先，为了计算非显示灰阶对应的预设亮度，屏幕需要确定至少两组显示灰阶对应的预设亮度，例如，屏幕确定(255，350)，(250，330)这两组显示灰阶对应的预设亮度。In this embodiment, first, in order to calculate the preset brightness corresponding to the non-display gray scale, the screen needs to determine at least two sets of preset brightness corresponding to the display gray scale, for example, the screen determines (255, 350), (250, 330) These two groups show the preset brightness corresponding to gray scale.
其次，屏幕根据插值法，计算出插值函数，其中，插值法可以采用任意合适的方法，例如，采用线性插值算法，计算出的插值函数为线性插值函数。例如，令y＝ax+b，将(255，350)，(250，330)分别代入上式，得到y＝4x-670。因此，对于在灰阶250至255之间，其对应的线性插值函数为y＝4x-670，因此，当未显示灰阶为251时，其对应的预设亮度为334nit，当251作为显示灰阶输入屏幕时，其便可以将亮度异常区域的亮度调节至334nit。Secondly, the screen calculates an interpolation function according to the interpolation method. Among them, the interpolation method can adopt any suitable method, for example, a linear interpolation algorithm is used, and the calculated interpolation function is a linear interpolation function. For example, let y=ax+b, substituting (255, 350) and (250, 330) into the above formula, respectively, to obtain y=4x-670. Therefore, for the gray level between 250 and 255, the corresponding linear interpolation function is y=4x-670, therefore, when the gray level is not displayed, the corresponding preset brightness is 334nit, when 251 is used as the display gray When step input screen, it can adjust the brightness of the abnormal brightness area to 334nit.
同理，当屏幕再次得到(128，160)这一组显示灰阶对应的预设亮度时，将(128，160)、(250，330)分别代入上式，得到y＝1.39x-18.4。因此，对于在灰阶128至250之间，其对应的线性插值函数为y＝1.39x-18.4，因此，当未显示灰阶为150时，其对应的预设亮度为190nit，当150作为显示灰阶输入屏幕时，其便可以将亮度异常区域的亮度调节至190nit。Similarly, when the screen again obtains the preset brightness corresponding to the set of gray levels of (128, 160), substitute (128, 160) and (250, 330) into the above equations, respectively, to obtain y=1.39x-18.4. Therefore, for the gray level 128 to 250, the corresponding linear interpolation function is y=1.39x-18.4, therefore, when the gray level is not displayed, the corresponding preset brightness is 190nit, when 150 is displayed When the gray scale input screen, it can adjust the brightness of the abnormal brightness area to 190nit.
