Detailed Description
Hereinafter, only certain exemplary embodiments are briefly described. As will be recognized by those of skill in the pertinent art, the described embodiments may be modified in various different ways without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.
Currently, an off-screen fingerprint technology and an off-screen camera technology have become important means for improving the screen duty ratio. As shown in fig. 1A, in order to implement an under-screen fingerprint recognition or an under-screen image capturing function, a display area AA of a display panel 10 is generally divided into a first display area AA1 and a second display area AA2, and functional devices such as a fingerprint recognition device or an image capturing device are disposed below the first display area AA1, so that light above the display panel 10 enters the functional devices through the first display area AA 1.
To ensure that light above the display panel 10 can pass through the first display area AA1, the thickness of the first display area AA1 is generally reduced. Referring to fig. 1A and 1B, taking the display panel 10 as an example of the flexible display panel 10A, the flexible display panel 10A has a display area AA and a non-display area VA located at the periphery of the display area AA, and the flexible display panel 10A includes a flexible substrate 11, a buffer heat dissipation layer 12, that is, a Super Clean Foam (SCF) layer, located at the backlight side of the flexible substrate 11, and a cover plate 13 located at the light emitting side of the flexible substrate 11, wherein the cover plate 13 is adhered to the flexible substrate 11 through an optical adhesive layer 14. In the case of the configuration under the first display area AA1 to assemble the fingerprint recognition device, the portion of the buffer heat dissipation layer 12 of the flexible display panel 10A located in the first display area AA1 is generally removed, so that the transmittance of the first display area AA1 is greater than the transmittance of the second display area AA 2. The inventors found in the practice of the present application that: since the transmittance of the first display area AA1 is greater than that of the second display area AA2, the first display area AA1 and the second display area AA2 of the display panel 10 generate display differences, such as brightness deviation or chromaticity deviation, so that a Mura phenomenon in visual sense appears; the related art mainly relies on human eyes to observe and subjectively describe the display difference between the first display area AA1 and the second display area AA2, and the description mode cannot objectively quantify the display difference, so that the accuracy of describing the display difference is low.
Based on the method, the display difference determination method can quantitatively represent the display difference of the first display area and the second display area of the display panel, and is beneficial to accurately describing the display difference of different types of display areas on the display panel. Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Fig. 2 is a flow chart illustrating a method for determining display differences according to an embodiment of the application.
As shown in FIG. 2, the method for determining the display difference includes the following steps S210 to S230.
Step S210, obtaining display parameters of at least one target area of the display panel. For example, referring to fig. 3 together, the display panel 10 includes a first display area AA1 and a second display area AA2, the second display area AA2 is located at the periphery of the first display area AA1, the target area 101 includes a partial area of the first display area AA1 and a partial area of the second display area AA2 of the display panel 10, the transmittance of the first display area AA1 is different from that of the second display area AA2, and the display parameters include the display parameters of the first display area AA1 and the display parameters of the second display area AA 2. The second display area AA2 may be located at one side of the first display area AA1, or may surround the first display area AA1, that is, the second display area AA2 at least partially surrounds the first display area AA1, which is not limited in the arrangement manner that the second display area AA2 is located at the periphery of the first display area AA 1. The display parameters are used to characterize the display effect.
Step S220, corresponding display difference coefficients are determined according to a plurality of display parameters of the target area.
Step S230, according to the display difference coefficient of the target area, determining the display difference of the first display area and the second display area.
In the above solution, the display parameters are obtained from at least one target area 101 including the partial area of the first display area AA1 and the partial area of the second display area AA2, so that the multiple display parameters of each target area 101 include the display parameters of both the first display area AA1 and the second display area AA2, and thus the local display difference of the first display area AA1 and the second display area AA2 in each target area 101 can be quantified by using the display difference coefficients determined by the multiple display parameters of each target area 101, and further the overall display difference of the first display area AA1 and the second display area AA2 can be quantified by using the display difference coefficients of at least one target area 101, which is beneficial to objectively and accurately describing the display difference of the first display area AA1 and the second display area AA 2.
When the display difference coefficient is determined by using the plurality of display parameters, the above scheme does not need to distinguish the display parameters of the first display area and the display parameters of the second display area from the plurality of display parameters, and only the display parameters of the first display area and the display parameters of the second display area need to be included in the display parameters, so that the determination method can be simplified, and the display difference can be more easily and quickly quantized.
In one embodiment, step S220 may include: calculating discrete coefficients of a plurality of display parameters in the target area; and setting the discrete coefficient as a display difference coefficient of the corresponding target area.
For example, please refer to fig. 3, the target area 101 is setThe display parameters are respectively/>、/>、……、Wherein/>For an integer of 1 or more, the discrete coefficient/>, of the plurality of display parameters of each target region 101 is calculated by the following formula (1)：
Formula (1)
Wherein,Represents the/>, within the target area 101Display parameters,/>Is greater than or equal to 1 and less than or equal to/>Is an integer of (2); /(I)For/>、/>、……、/>Average value of/(I)Can be calculated by the following formula (2):
Formula (2)
In the target region 101, the discrete coefficients of the plurality of display parameters may characterize the degree of the dispersion of the plurality of display parameters, i.e., the degree of the difference between the plurality of display parameters. The smaller the discrete coefficient is, the lower the discrete degree is, the smaller the degree of difference between the plurality of display parameters is, the smaller the display difference between the first display area AA1 and the second display area AA2 in the target area 101 is, and the better the display uniformity is; the larger the discrete coefficient is, the larger the degree of difference between the plurality of display parameters is, and the larger the display difference between the first display area AA1 and the second display area AA2 in the target area 101 is, the worse the display uniformity is.
In the above solution, the discrete coefficients of the multiple display parameters of the target area 101 are used as the display difference coefficients of the corresponding target area 101, so that the degree of difference between the multiple display parameters in the target area 101 can be accurately represented, and thus the local display difference of the first display area AA1 and the second display area AA2 in the target area 101 can be accurately quantified.
In one embodiment, referring to fig. 3, the target area 101 includes a plurality of sub-target areas (not shown in fig. 3) uniformly distributed in the target area; calculating discrete coefficients for a plurality of display parameters of the target region 101 includes: acquiring display parameters of a plurality of sub-target areas of the target area 101; discrete coefficients of display parameters of the plurality of sub-target areas are calculated.
Illustratively, the sub-target area includes an area in which at least one pixel is located. A pixel may be composed of one R sub-pixel, one G sub-pixel, and one B sub-pixel adjacent to each other. The sub-target area may be an area where one pixel point is located, or may be an area where a plurality of adjacent pixel points are located. Correspondingly, the display parameter of one sub-target area in the acquisition target area 101 may be the display parameter of one pixel point in the acquisition target area 101, or may be the display parameters of a plurality of adjacent pixel points in the acquisition target area 101.
Illustratively, the display parameters of the plurality of sub-target areas of the acquisition target area 101 may be display parameters of all pixel points within the acquisition target area 101. When the sub-target area is an area where one pixel is located, the ratio between the number of obtained display parameters and the number of pixels in the target area 101 is 1:1, and taking the number of all pixels in the target area 101 as 100 as an example, the number of obtained display parameters in the target area 101 is 100. When the sub-target area is an area where a plurality of adjacent pixel points are located, the ratio of the number of the obtained display parameters to the number of the pixel points in the target area 101 is 1:k, wherein k is an integer greater than or equal to 2, and k is the number of the pixel points in the plurality of adjacent pixel points; taking the number of all the pixels in the target area 101 as 100 as an example, if k=2, the area where two adjacent pixels are located is a sub-target area, and further, the display parameters in the target area 101 are obtained to be 50.
In the above solution, since the plurality of sub-target areas are uniformly distributed in the target area 101, and the display parameters of the plurality of sub-target areas are used as the plurality of display parameters of the target area 101, the number of the display parameters of the first display area AA1 and the number of the display parameters of the second display area AA2 in the plurality of display parameters are similar, so that the calculated discrete coefficient can more accurately quantify the local display difference between the first display area AA1 and the second display area AA2 in the target area 101.
In one embodiment, the display parameters include, but are not limited to, luminance values and/or chrominance values. When the display parameter is a luminance value, the display difference coefficient determined by the display parameter is a luminance difference coefficient, and the display difference determined by the display difference coefficient is a display luminance difference. When the display parameter is a chromaticity value, the display difference coefficient determined by the display parameter is a chromaticity difference coefficient, and the display difference determined by the display difference coefficient is a display chromaticity difference. It will be appreciated that the display parameters may also be selected and adjusted according to actual needs, as the application is not limited in this regard.
In an alternative embodiment, the target area comprises one; step S230 includes: the display difference coefficient of one target area 101 is taken as the display difference quantized value of the first display area AA1 and the second display area AA 2. For example, please refer to fig. 3 together, an example is illustrated in which the target area 101 is 1. Setting the display difference coefficient of the target area 101 asWill/>As a display difference quantization value of the first display area AA1 and the second display area AA 2. Thus, it is possible to utilize/>The display difference of the first display area AA1 and the second display area AA2 is quantified.
In another alternative embodiment, the target area includes a plurality of; the plurality includes two or more; step S230 includes: the maximum display difference coefficient in the plurality of target areas 101 is taken as the display difference quantized value of the first display area AA1 and the second display area AA 2. The display difference quantized values of the first display area AA1 and the second display area AA2 may be used as Mura quantized values of the first display area.
For example, please refer to fig. 3 together, an example of 4 target areas 101 is illustrated. Setting the display difference coefficients of the 4 target areas 101 as、/>、/>、/>Will/>、/>、/>、/>The maximum value of (a) is used as a display difference quantized value of the first display area AA1 and the second display area AA 2. Thus, it is possible to utilize/>、/>、/>、/>The maximum value of (a) quantifies the display difference of the first display area AA1 and the second display area AA 2.
In one application scenario, the transmittance of the first display area AA1 is greater than the transmittance of the second display area AA 2. The determination method of the present application can quantify the display difference between the first display area AA1 and the second display area AA2 having different transmittance.
In another application scenario, the first display area AA1 is an area where an under-screen fingerprint identification device or an under-screen image acquisition device is located, and the second display area AA2 is a normal display area. The method for determining the display difference of the first display area AA1 and the second display area AA2 in the application scene can be used for quantifying the display difference of the first display area AA1 and the second display area AA2 in the application scene.
In one embodiment, as shown in fig. 3, the first display area AA1 is polygonal, and the side length of at least one side L of the first display area AA1 ranges from 8mm to 10mm (including the end point value). For example, the side length L of at least one side of the first display area AA1 may be any one of 8mm, 9mm, and 10 mm. It should be noted that the first display area AA1 includes, but is not limited to, regular polygons such as diamond, rectangle, and other irregular polygons.
In one embodiment, as shown in fig. 4A, the second display area AA2 at least partially surrounds the first display area AA1, and the step S210 includes the following steps S211 to S214.
Step S211, an image of the display panel is acquired. For example, an image of a display panel may be acquired using an area imaging device such as an imaging luminance meter, the image of the display panel containing display parameters for each pixel in the display panel, the display parameters including luminance values and/or chrominance values.
Step S212, dividing the image of the display panel into a first image and a second image, wherein the first image is an image of the first display area, and the second image is an image of the second display area. In practical application, the position information of the first display area on the display panel is preset information, and the position information can be obtained after the display panel is designed. Referring to fig. 4B together, step S212 may be to divide the first image 41 from the image 40 of the display panel based on the position information of the first display area on the display panel, and then the rest of the image areas except the first image 41 in the image 40 of the display panel form the second image 42.
Step S213, dividing a partial image area of the first image and the second image, which is located at the periphery of the first image, into images of target areas. For example, as shown in fig. 4C, the partial image area of the first image 41 and the second image 42 located at the periphery of the first image 41 is divided into the images 40A of the plurality of target areas, and the images 40A of the respective target areas may include both the partial area of the first image 41 and the partial area of the second image 42. Note that fig. 4C only shows a partial region of the dashed box B in fig. 4B.
Step S214, correspondingly acquiring display parameters of the target area from the image of the target area.
In the above-mentioned scheme, since the image 40 of the display panel includes the display parameters of each pixel in the display panel, after at least one image 40A of the target area is divided from the image 40 of the display panel, the display parameters of the target area can be obtained from the image 40A of the target area correspondingly, and the implementation manner is simple.
In one embodiment, referring to fig. 3 and 4B together, the image 40 of the display panel is obtained when the first display area AA1 and the second display area AA2 of the display panel 10 are both illuminated. Thus, the display parameters conforming to the practical application can be acquired from the image 40 of the display panel, and the accuracy of the display difference quantification can be improved.
In one embodiment, the outer contour shape of the first image 41 is polygonal, for example, the outer contour shape of the first image 41 includes, but is not limited to, regular polygons such as diamond, rectangular, and other irregular polygons.
Referring to fig. 4C, step S213 includes: at least one edge 41A of the first image 41 is taken as a center line; the partial image areas of the first image 41 and the second image 42 adjacent to the same center line are divided into the image 40A of the same target area, and the outer contour shape of the image 40A of the target area is made symmetrical with respect to the center line to obtain the image 40A of the target area. Illustratively, the outer contour shape of the image 40A of the target area includes, but is not limited to, a symmetrical pattern of circles, ovals, rectangles, regular triangles, and the like.
In the above-mentioned scheme, the outer contour shape of the image 40A of the target area is set to be a symmetrical graph about the corresponding edge 41A of the first image 41, so that the areas of the first image 41 and the second image 42 in the image 40A of the target area are the same, and thus, the same number of display parameters of the first display area and display parameters of the second display area can be obtained from the image 40A of the target area, which is beneficial to more accurately quantifying the display difference between the first display area and the second display area.
In one embodiment, referring to fig. 4C together, the entire area of the first image 41 is completely divided into the images 40A of the plurality of target areas. In this way, in the case of acquiring the display parameters from the images 40A of the plurality of target areas, it is possible to acquire all the display parameters of the first display area, avoiding a decrease in accuracy of quantization due to omission of a part of the display parameters of the first display area.
In one embodiment, referring to fig. 4C, the outer contour of the image 40A of the target area is circular, the outer contours of the images 40A of two opposite target areas are tangent, and the outer contours of the images 40A of two adjacent target areas intersect. Therefore, not only can all the display parameters of the first display area be ensured to be acquired, but also the repeated acquisition quantity of the display parameters can be reduced, and the calculation speed is improved.
The application also provides another method for determining the display difference, as shown in fig. 5, which comprises the following steps S510-S520.
Step S510, controlling the display panel to display a plurality of image frames respectively; the gray scales of the plurality of image frames are different. Referring to fig. 3, when the display panel 10 displays any image, the first display area AA1 and the second display area AA2 of the display panel 10 have the same gray scale. For example, when the gray scale of the image frame displayed on the display panel 10 is 255, the gray scales of the contents displayed on the first display area AA1 and the second display area AA2 are 255. In practical applications, the image frame may be a white image frame.
In step S520, when the display panel displays any one of the image frames, the determining method according to any one of the embodiments is used to determine the display difference between the first display area and the second display area of the display panel, so as to obtain the display difference under different gray scales.
In this way, after the display panel 10 finishes displaying a plurality of image frames, the display differences of the first display area AA1 and the second display area AA2 under a plurality of different gray scales can be determined, so as to realize the quantification of the display differences under different gray scales.
