The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a schematic structural diagram of an electronic device provided in an application scenario of the present application, where the electronic device 1 shown in fig. 1 may be an electronic device having a display panel 10, such as a mobile phone and a tablet computer, and the display panel may specifically be an Organic Light-Emitting semiconductor (OLED) screen, taking the electronic device 1 as an example in fig. 1. Some electronic devices 1 propose a concept of "full screen" in order to increase the occupation ratio of the display panel 10, and the display panel 10 provided in the electronic device 1 shown in fig. 1 covers all positions of the whole display side, so that the electronic device 1 can present a more complete display effect.
In some embodiments, the electronic device 1 is further provided with an Under-screen photosensitive module such as an Under-screen Display Camera (UDC) and an Under-screen fingerprint recognition device on a non-Display side of the Display screen, in order to enable the functional modules to realize related functions, a region of the Display panel 10 above the functional modules needs to adopt a new organic film and an inorganic film with higher transparency, a metal layer structure of a Display screen body is optimized to improve light transmittance of the region, the Under-screen photosensitive module collects light in operation using the region, a region corresponding to the Under-screen photosensitive modules is denoted as a first Display region 102, and a region outside the first Display region 102 on the Display panel and unrelated to the function of the Under-screen photosensitive module is denoted as a second Display region 101. When the functional module below the display panel 10 is not in the working state, the first display area 102 on the display panel 10 can implement a display function together with the first display area 101 on the whole display panel 10, providing a display effect of a "full screen"; when the functional module is in a working state, the first display area 102 on the display panel 10 can transmit light above the display panel 10 to the functional module below, so that the functional module can implement functions such as image pickup and fingerprint identification according to the received light.
In some embodiments, in order to match the arrangement of the off-screen photosensitive module of the display panel 10 of the electronic device 1 shown in fig. 1, the setting parameters of the pixels, such as the pixel arrangement, the pixel density, and the like, in the first display area 102 are different from the setting parameters in the second display area 101, so that there is a display deviation between the first display area 102 and the second display area 102, which brings about a sensory difference when the display panel 10 is viewed by human eyes. Therefore, in some technologies, an operator may perform a quantitative test for the display difference between two different types of areas on the display panel 10 by using a luminance meter, a colorimeter, or the like. However, when the display difference between the two areas is tested in this technique, the whole first display area 102 is compared with the whole second display area 101, and regarding all the display areas on the whole display panel 10 as a whole may weaken the difference between the two display areas, and may not more accurately compare the more obvious display difference existing at the adjacent junction between the two display areas at the pixel level, which also results in poor precision of the obtained display difference, so that the production designer of the subsequent electronic device 1 may not more accurately adjust the pixel setting parameters of the different display areas, and further affect the appearance of the display panel 10 of the electronic device 1, and reduce the user experience of the electronic device 1.
Therefore, the present application provides a method and an apparatus for determining display differences of a display panel, which divide a display area into different sub-areas, and compare display parameters of adjacent sub-areas in two different display areas to determine display differences between the two display areas corresponding to adjacent positions, so as to more accurately determine display color differences between different types of areas on the display panel, thereby facilitating subsequent production designers to more accurately adjust display setting parameters of different areas on the display panel, improving the appearance of the display panel, and improving user experience of electronic devices.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a flowchart illustrating an embodiment of a method for determining a display difference of a display panel according to the present application, wherein the method shown in fig. 2 can be used to determine a display difference between a first display area 102 and a second display area 101 on a display panel 10 of an electronic device 1 shown in fig. 1. The main body of the method may be a device for determining the display difference of the display panel, for example, fig. 3 is a schematic diagram of a device for performing the method for determining the display difference of the display panel, which may be an electronic device 2 such as a mobile phone or a computer having an imaging device 21, and the electronic device is exemplified as a computer in fig. 2.
Specifically, the method for determining the display difference of the display panel as shown in fig. 1 includes:
s101: when a first display area and a second display area on a display panel of the electronic equipment are both lightened, images of a plurality of first sub-areas in the first display area and images of a plurality of second sub-areas in the second display area in the display panel are obtained.
Taking the electronic device 1 shown in fig. 1 as an example, when none of the photosensitive modules under the screen issued by the display panel 10 of the electronic device 1 is in an operating state, both the first display area 102 and the second display area 101 on the display panel 10 can be used to be lit for displaying, at this time, the device 2 for determining the display difference of the display panel can perform photographing and imaging on the display panel 10 through the imaging device 21 such as a camera, a spectrometer or an Mk6-12 scanner, and an image of a first sub-area in the first display area 102 and an image of a second sub-area in the second display area 101 in an image displayed by the display panel 10 are obtained. Alternatively, in some embodiments, the apparatus 2 for determining the display difference of the display panel as the execution subject may further receive the image 100 transmitted by the tester, the image including the images displayed on the first display area 102 and the second display area 101 of the display panel 10.
The embodiment of the present application does not limit the specific content displayed on the display panel 10 of the electronic device 1, and when the display panel 10 displays the content, the first display area 102 and the second display area 101 on the display panel 10 are both lit, and the first display area 102 and the first display area 101 display the content in the same gray scale correspondingly. For example, the content displayed on the display panel 10 by the electronic apparatus 1 may be an image having a grayscale value of W255, 128, 64, 32, 2nit32, or the like. Alternatively, the device 2 for determining the display difference of the display panel may further send a test instruction to the electronic device 1, control the electronic device 1 to switch to the test state, turn off the off-screen photosensitive module of the electronic device 1, and display the image corresponding to the same gray scale on the display panel 10. In addition, when the display panel 10 displays content, it can be in any one of a High Brightness Monitor (HBM) mode or a Normal mode (Normal) mode, and it is only necessary to ensure that the displayed content corresponds to the same gray level in the first display area 102 and the first display area 101.
Exemplarily, in the example shown in fig. 3, the apparatus 2 determining the display difference of the display panel first controls the electronic device 1 to display an image through the first display area 102 and the first display area 101 thereof in step (r), and controls the imaging device 21 to capture an image of the display 10 by the processing module 22 such as a CPU in the apparatus 2 in step (corresponding to S101 in fig. 1), and then performs subsequent processing by the processing module 22 through step (corresponding to S102 in fig. 2).
In some embodiments, fig. 4 is a schematic diagram of dividing sub-regions of a display area provided in the present application, and as shown in fig. 4, taking a partial region of the image 100 acquired in S101 as an example, in the region shown in fig. 4, a position on the display panel 10 adjacent to the first display region 102 and the first display region 101 is shown, the first display region 102 is on one side of a boundary 103, and the second display region 101 is on the other side of the boundary 103. In S102, the first display area 102 shown in fig. 4 is divided into a plurality of sub areas and recorded as a first sub area, and the second display area 101 is divided into a plurality of sub areas and recorded as a second sub area according to the preset division rule of the sub areas.
In some embodiments, the preset partitioning rule of the sub-region includes: dividing a region to be divided into a plurality of sub-regions with preset shapes, wherein the preset shapes of the sub-regions comprise: a circle with a diameter of 1-10 mm or a quadrangle with at least one side length of 1-10 mm. For example, in the example shown in fig. 4, the preset shape of each sub-region is a circle. The pre-set shape of the sub-area may be selected from a circle with a diameter of 1.56mm or 7.88 mm. Meanwhile, the area of each region may correspond to a setting parameter of a camera device that acquires an image, and for example, when an image is acquired using a spectrometer, if the spot size of the spectrometer is 0.2 °, the diameter of the circular sub-region may be set to 1.56 mm; if the spot size of the spectrometer is 1 deg., the diameter of the circular sub-area can be set to 7.88 mm. Taking fig. 4 as an example, according to a circular division rule with a diameter of 1.56mm, the first display area 102 in fig. 4 may be divided into 12 circular first sub-areas, which are sequentially numbered 1-12, and the second display area 101 may be divided into a plurality of circular second sub-areas, since the second display area 101 has a larger area, fig. 4 only shows a plurality of circular second sub-areas adjacent to the first display area 102 in the second display area 101, which are sequentially numbered 13-24.
In some embodiments, the preset partition rule of the sub-regions provided by the present application may be stored in advance in a device for determining the display difference of the display panel as an execution subject; alternatively, the staff may be stored in the device before S101; still alternatively, the means for determining the display difference of the display panel may also determine a specific division rule of the sub-area according to an image capturing parameter of an image capturing device used for currently obtaining the image, for example, a size of an aperture; or, the device for determining the display difference of the display panel may further receive the setting parameters sent by the staff, and determine the division rule of the corresponding sub-region according to the received setting parameters, in some embodiments, the device for determining the display difference of the display panel may further store a one-to-one correspondence relationship between a plurality of different setting parameters and the sub-region division rule, and after the setting parameters are obtained, the specific sub-region division rule may be determined according to the correspondence relationship. Still alternatively, the division rule of the sub-regions may be determined according to the area of the second display region of the display device to be acquired, for example, when the longest diagonal line of the area of the second display region is 5mm, a plurality of regions in the second display region may not be acquired by using the division rule of 7.88mm, and thus the division rule of 1.56mm in diameter may be used.
In some embodiments, when the spectrometer is used to collect an image in S101, the spectrometer may be controlled to sequentially acquire an image of the first sub-region and an image of the second sub-region in units of sub-regions according to a preset division rule, and then process the images together in subsequent steps; when the image is acquired by using the surface scanner in S101, the whole image of the display panel may be acquired, and then the image is split according to the preset division rule, so as to obtain the image of the first sub-region and the image of the second sub-region.
S102: according to the display parameters of the plurality of first sub-areas in the first display area 102 and the second display parameters of the plurality of second sub-areas in the second display area 101 in the image, the display difference between the first display area 102 and the second display area 101 on the display panel 10 is determined.
Specifically, the display area is divided into different sub-areas, so that the difference between the two display areas can be determined through the difference of display parameters between adjacent sub-areas in different display areas. The display parameter provided by the application can be one or more of brightness, chroma, a brightness uniformity value, a chroma uniformity value, a uniformity difference value, color cast and a color difference.
In some embodiments, in S102, the first sub-area and the second sub-area that are adjacent to each other are specifically determined from between the first display area 102 and the second display area 101, and then the difference of the display parameters between the two display areas is determined according to the difference of the display parameters between each two adjacent sub-areas. For example, in the example shown in fig. 4, a second sub-area with reference number 13 in the second display area 101 is determined to be correspondingly adjacent to a first sub-area with reference number 1 in the first display area 102, and then the first display parameter of the first sub-area and the second display parameter of the second sub-area in the image acquired in S101 are determined, for example, when the display parameter is color cast, the chromaticity u of the first sub-area may be acquired1′v1', and the chromaticity u of the second sub-region2′v2' and then substituting the chromaticities of the two subregions into the formula
A color shift au 'v' between the second sub-area, referenced 13, and the first sub-area, referenced 1, can be obtained. Subsequently, in the same manner as described above, the correspondingly adjacent sub-regions in the two display regions, which are denoted by reference numerals 12 and 14, 12 and 16, 11 and 17, are sequentially used as the first sub-region and the second sub-region, and the above calculation is performed, so that the color shift Δ u 'v' between all the adjacent sub-regions can be finally obtained by one circle of the boundary 103 between the first display region 102 and the second display region 101. These color shifts Δ u 'v' can be used to quantify the display differences between the first display area 102 and the second display area 101 on the display panel, and to represent the display differences by sub-areas at the pixel level, which can increase the granularity of representation and more accurately represent the display differences that determine the location of adjacent boundaries between different types of areas on the display panel.
In other embodiments, to further increase the granularity of quantization of the display difference between the first display region 102 and the second display region 101, when comparing the display parameters of the sub-areas within the first display area 102 and the sub-areas within the second display area 101, based on the display panel, the display parameters between adjacent sub-areas of two display areas may have smaller display errors, the display difference at that position cannot be accurately corresponded to in the display parameters compared, and therefore in some operating conditions the display panel obtained, in the case where the display error of the sub-areas not adjacent to each other on the boundary is larger than that of the adjacent sub-areas, each sub-area in one display area may be further divided, comparing with the sub-areas of all other boundary positions in another display area to obtain the color cast between the sub-areas of more boundary positions, therefore, the display difference of the adjacent boundary positions between different types of areas on the display panel can be determined more comprehensively and accurately. For example, taking the image 100 shown in fig. 4 as an example, it may be determined that the sub-region labeled 1 in the first display region 102 is the first sub-region, and then, a plurality of second sub-regions labeled 13-24 adjacent to the first display region 102 in the second display region 101 are determined, and the first display parameter of the first sub-region labeled 1 and the plurality of second sub-regions labeled 13-24 are sequentially calculated to obtain a plurality of color shifts Δ u 'v', respectively. In the same manner, after a plurality of color cast Δ u 'v' is obtained by sequentially calculating a plurality of first sub-areas adjacent to the second display area 101 and a plurality of second sub-areas in each first display area 102, a color cast Δ u 'v' obtained by combining any two sub-areas at all boundary positions between the first display area 102 and the second display area 101 can be obtained, and then the display difference between the two display areas can be determined according to the color cast Δ u 'v'.
In some embodiments, in addition to quantifying the display differences by calculating the color shift Δ u 'v' as described above, color shifts can also be calculated by way of CIE1976LAB, calculating the color shifts Δ E ab and Δ C ab between two subregions.
In the foregoing example of the embodiment, the display parameter is taken as an example of color cast, and in other possible implementation manners, when the display parameters in two different display areas are compared in S102, the display parameters may also be determined according to different sub-areasThe luminance, chrominance, etc. of the field, quantitatively describe the display difference between the two display regions. Such as brightness, uniformity, etc. For example, in S103, an average value of the luminance of the pixels in each sub-area in the first display area, denoted as P1, P2, … …, and P12, may be obtained, and a luminance deviation U1 of the first display area, which is the ratio of the minimum luminance to the maximum luminance of the first display area, is determined according to the minimum luminance and the maximum luminance in the first display area. Similarly, the luminance deviation U2 ═ brightness (min)/brightness (max) of the first display area can also be determined according to the ratio of the minimum luminance to the maximum luminance in the average value of the luminance of the pixels in all the sub-areas in the second display area. Then, the luminance difference between the two display regions may be calculated according to the formula Δ U — U1-U2, and the calculated Δ U may be used to represent the display difference between the two display regions. For another example, after obtaining the luminance difference between the two display regions, the following formula can be applied
And calculating a parameter delta L for quantifying the display difference between the two areas, wherein 0.004 is an experience value, and adaptive adjustment and setting can be performed according to different scenes.
It can be understood that, after the quantization parameter is obtained to indicate the display difference existing between the two display areas, the worker may subsequently adjust the brightness and the chromaticity of the pixel at the corresponding position in the display panel 10 of the electronic device 1 according to the display difference, so that the display difference between the two display areas satisfies the condition. For example, after obtaining the quantization parameter that can indicate the display difference between the two display regions, the quantization parameter is compared with a preset threshold, and if the quantization parameter is greater than the preset threshold, the display unevenness between the two display regions of the display device is determined, and then the adjustment can be performed by a worker.
