技术领域Technical field

本申请实施例涉及但不限于一种显示屏调整方法及装置、计算机可读存储介质。The embodiments of the present application relate to, but are not limited to, a display screen adjustment method and device, and a computer-readable storage medium.

背景技术Background technique

显示屏由于生产工艺复杂，使用的材料种类非常多，再加上人眼对于显示颜色又非常敏感，因此，不同批次或者相同批次的显示屏之间都会存在色差。显示屏厂家通过对每一个显示屏都调节其驱动电压，改变其白平衡，使得每一个显示屏的白平衡都与目标值接近，缩小显示屏之间的色差。Due to the complicated production process of the display screen, there are many types of materials used, and the human eye is very sensitive to the display color. Therefore, there will be color differences between the display screens of different batches or the same batch. Display manufacturers adjust the driving voltage of each display and change its white balance so that the white balance of each display is close to the target value, reducing the color difference between the displays.

目前减小显示屏色差，调整白平衡都在显示屏生产厂家实现，显示屏生产厂家提供的显示屏都是经过白平衡校准的方法，减小显示屏之间的色差。但是，使用校准设备进行校准的时候，由于误差的存在，两个显示屏仍然可能存在一定的色差。At present, reducing the color difference of the display screens and adjusting the white balance are implemented by the display manufacturer. The display screens provided by the display manufacturers are all calibrated by white balance to reduce the color difference between the display screens. However, when using a calibration device for calibration, there may still be a certain color difference between the two displays due to the existence of the error.

具体实施方式Detailed ways

下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。The embodiments of the present application will be described in detail below with reference to the drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.

在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机***中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。The steps shown in the flowchart of the figures may be performed in a computer system such as a set of computer-executable instructions. And, although the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than here.

显示屏厂家进行白平衡校准的方法的缺点在于，校准完成后，显示屏显示的白色画面是一个固定的状态，当显示屏厂家使用很多的校准设备进行校准的时候，不同校准设备之间存在差异，因此，校准出来的白平衡也存在差异，所以，不同的屏幕之间依然存在一定的色差。当新的产品形态出现后，例如，两个屏幕可以折叠拼成一个屏的时候，如果两个屏幕之间的色差要求非常高，通常需要继续调整白平衡，才能让两个屏幕之间的色差缩小。The disadvantage of the display manufacturer's white balance calibration method is that after the calibration is completed, the white screen displayed on the display is a fixed state. When the display manufacturer uses a lot of calibration equipment for calibration, there are differences between different calibration equipment. Therefore, there are also differences in the calibrated white balance, so there is still a certain color difference between different screens. When the new product form appears, for example, when two screens can be folded to form a screen, if the color difference between the two screens is very high, it is usually necessary to continue to adjust the white balance to make the color difference between the two screens. Zoom out.

另外，随着AMOLED(Active-Matrix Organic Light Emitting Diode，有源矩阵有机发光二极体)显示屏的发展，越来越多的终端使用了AMOLED屏，但是主动发光技术的显示屏都有一个老化的过程，因此使用过程中经常点亮的部分会老化的更快，导致这一部分显示颜色跟其他地方的颜色不同。柔性屏从中间折弯180度，变成原来的一半的时候，其中的一半使用时间长，另一半很少用到，AMOLED屏幕随着使用时间加长，会出现烧屏的现象，烧屏的现象是屏幕随着时间的变长显示颜色会慢慢变黄，那么显示屏的两个半屏会出现色差，因此需要调节其中一个屏幕的颜色才能减小色差。In addition, with the development of AMOLED (Active-Matrix Organic Light Emitting Diode) displays, more and more terminals use AMOLED screens, but the displays of active light technology have an aging Process, so the part that is often lit during use will age faster, resulting in the display color of this part being different from the color of other places. When the flexible screen is bent 180 degrees from the middle, it becomes half of the original time. Half of the screen is used for a long time and the other half is rarely used. As the use time of the AMOLED screen increases, the screen burn-in phenomenon will occur. It is because the screen becomes yellow gradually over time, and then the two half screens of the display will have a color difference, so the color of one of the screens needs to be adjusted to reduce the color difference.

当前调节显示屏颜色的方法主要是利用色温的方式进行调节，调节色温从暖色调到冷色调是一个单方向的调节方式，当有两个显示屏的时候，两个显示屏的调节过程中，两个屏幕不一定有交叉点，所以两个屏幕利用色温的方式不一定可以实现调整到显示一致。The current method of adjusting the color of the display screen is mainly to adjust the color temperature. Adjusting the color temperature from warm to cold is a one-way adjustment method. When there are two displays, the adjustment process of the two displays, The two screens do not necessarily have intersections, so the way in which the two screens use color temperature may not necessarily achieve a consistent display.

本申请实施例中，通过在两个显示屏上显示同一图片，并提供至少一个调整模块，实现对显示屏的调整以达到显示屏的一致。In the embodiment of the present application, by displaying the same picture on two display screens and providing at least one adjustment module, adjustment of the display screen is achieved to achieve uniformity of the display screens.

在一实施例中，还包括：In an embodiment, the method further includes:

获取所述调整模块对应的显示模块分别显示多个预设纯色图片时的多个色度坐标和亮度信息；其中，多个预设纯色图片比如纯白图片、红色图片、绿色图片、蓝色图片。可以显示不同灰阶下的纯白图片、红色图片、绿色图片、蓝色图片。此处红色、绿色、蓝色是指三原色。其中，可以通过色度采集设备采集色度坐标。Obtain multiple chromaticity coordinates and brightness information when the display module corresponding to the adjustment module displays multiple preset solid color pictures, respectively, where multiple preset solid color pictures such as pure white pictures, red pictures, green pictures, and blue pictures . Can display pure white pictures, red pictures, green pictures, blue pictures under different gray levels. Here red, green and blue refer to the three primary colors. Among them, chromaticity coordinates can be collected by a chromaticity acquisition device.

所述调整模块的位置与色度坐标存在对应关系，所述根据所述调整滑块的位置调整所述调整模块对应的显示模块的显示寄存器的值包括：There is a corresponding relationship between the position of the adjustment module and chromaticity coordinates, and the value of the display register of the display module corresponding to the adjustment module according to the position of the adjustment slider includes:

The value of the display register of the display module corresponding to the block is adjusted according to the determined value of the display register.

比如，显示屏IC中，R(红色)，G(绿色)，B(蓝色)三种颜色对应的电驱动压分别有0到255级，初始状态下，背光亮度最大，测得红色，绿色，蓝色三种颜色在驱动电压为第255级时的色度坐标值和亮度值，测得W(白色)在驱动电压为第255级时的色度坐标值和亮度值(此时R，G，B对应的驱动电压均在第255级)，再测电压为63，127，191级时，R(红色)，G(绿色)，B(蓝色)，W(白色)时的色度坐标值和亮度值。For example, in the display IC, the electrical driving voltages corresponding to the three colors of R (red), G (green), and B (blue) are 0 to 255. In the initial state, the backlight brightness is the largest, and the red and green are measured. , The chromaticity coordinate value and brightness value of the three blue colors when the driving voltage is 255th level, the chromaticity coordinate value and brightness value of W (white) when the driving voltage is 255th level (R, The driving voltages corresponding to G and B are in the 255th level). When the retest voltage is 63,127,191, the chromaticity at R (red), G (green), B (blue), and W (white) Coordinate and brightness values.

在一实施例中，测得白色在第255级时的色度坐标例如为(0.31,0.32)，当调整滑块的位置对应的当前色度坐标为(0.30,0.32)时，根据前面测量的第63、127、191、255级的色度坐标值和亮度值，以及，当前的色度坐标值，计算出显示寄存器的值，计算时根据显示屏厂家给出的显示屏的校准公式进行计算，计算时，需考虑gamma值，使得gamma值满足需求。显示寄存器的值与驱动电压存在对应关系，改变显示寄存器的值，则改变了各像素单元的驱动电压，进而改变了显示屏的颜色。In an embodiment, the measured chromaticity coordinate of white at the 255th level is, for example, (0.31,0.32). When the current chromaticity coordinate corresponding to the position of the adjustment slider is (0.30, 0.32), according to the previously measured The 63, 127, 191, and 255 levels of chromaticity coordinate values and brightness values, and the current chromaticity coordinate values, the value of the display register is calculated, and the calculation is performed according to the calibration formula of the display screen given by the display manufacturer. When calculating, you need to consider the gamma value to make the gamma value meet the requirements. There is a corresponding relationship between the value of the display register and the driving voltage. Changing the value of the display register changes the driving voltage of each pixel unit, thereby changing the color of the display screen.

在一实施例中，所述调整区域比如为一矩形区域，其中心对应的色度坐标为(0.30,0.32)，该区域中色度坐标(x,y)的x值从0.27到0.33，y值从0.29到0.35，初始时调整滑块的色度坐标为(0.30，0.32)，该值为显示模块进行生产时纯白色画面的目标色度坐标(即显示模块显示纯白色画面时，调整显示寄存器的值，使得屏幕的色度坐标为(0.30，0.32)，如果用户将调整滑块滑动到(0.31,0.33)，则根据色度坐标(0.31,0.33)以及初始时测量的多组色度坐标和亮度信息，确定显示寄存器的值。本实施例中，滑块最小移动距离0.001，当然，也可以设置为其他值。需要说明的是，目标色度坐标也可以是其他值。本实施例中，将gamma值设置为2.2。当然，也可以设置为2.0至2.4之间的其他值。In an embodiment, the adjustment region is, for example, a rectangular region, and the chromaticity coordinate corresponding to the center thereof is (0.30, 0.32), and the x value of the chromaticity coordinate (x, y) in the region is from 0.27 to 0.33, y The value is from 0.29 to 0.35. Initially, the chromaticity coordinate of the adjustment slider is (0.30, 0.32). This value is the target chromaticity coordinate of the pure white screen when the display module is in production. The value of the register makes the chromaticity coordinates of the screen to be (0.30, 0.32). If the user slides the adjustment slider to (0.31,0.33), then according to the chromaticity coordinates (0.31,0.33) and the multiple sets of chromaticity measured at the beginning The coordinates and brightness information determine the value of the display register. In this embodiment, the minimum moving distance of the slider is 0.001. Of course, it can also be set to other values. It should be noted that the target chromaticity coordinates can also be other values. This embodiment , Set the gamma value to 2.2. Of course, it can also be set to other values between 2.0 and 2.4.
