In the production process of various types of display screens such as self-luminous LED/OLED/MicroLED/MiniLED display screens, the attenuation degree of different lamp beads in the self-luminous LED/OLED/MicroLED/MiniLED display screens can be different due to the material process, the production packaging process and the like of the lamp beads, and further the situation of inconsistent attenuation of the whole screen occurs in the use process. Therefore, before the self-luminous display screen is delivered, correction is usually performed on the self-luminous display screen point by point. In the related art, the self-luminous display screen is usually required to be photographed, and the compensation data of each lamp bead is determined according to the image data of each lamp bead, so as to correct the self-luminous display screen. However, in this process, the image data of the lamp bead may be affected by the external environment light, especially, since the exposure time for photographing is long, the external environment light is difficult to keep stable, which may result in a low accuracy of the compensation data obtained according to the image data of the lamp bead, and affect the correction effect on the self-luminous display screen.
The disclosed embodiment provides a self-luminous display screen correction method, which can be applied to a self-luminous display screen of electronic equipment, wherein at least one first lamp bead in the self-luminous display screen is lightened, at least one second lamp bead is extinguished, at least one second lamp bead in the adjacent lamp bead of each lightened first lamp bead is extinguished, by acquiring an image obtained by shooting the self-luminous display screen, and acquiring first image data corresponding to the first lamp bead and second image data corresponding to the second lamp bead according to the image, and aiming at the first image data corresponding to each first lamp bead, according to the second image data corresponding to the adjacent second lamp beads, correcting the first image data to obtain third image data, and after at least part of the second lamp beads are lightened, and re-executing the steps of obtaining the image obtained by shooting the self-luminous display screen and the subsequent steps until third image data of all lamp beads in the self-luminous display screen are obtained. Through according to the second image data that second lamp pearl corresponds, carry out the correction to the first image data that first lamp pearl corresponds, can obtain the higher third image data of accuracy, and then when proofreaying based on third image data to self-luminous display screen, can reduce variable ambient light influence, effectively strengthen self-luminous display screen correction effect.
Fig. 1 shows a flowchart of a self-luminous display screen calibration method according to an embodiment of the present disclosure. As shown in fig. 1, the self-luminous display screen calibration method may include:
in step S11, an image obtained by shooting the self-luminous display screen is obtained, wherein at least one first lamp bead in the self-luminous display screen is lit, at least one second lamp bead is extinguished, and at least one extinguished second lamp bead in the adjacent lamp bead of each lit first lamp bead.
The self-luminous display screen is formed by lamp bead combination arrangement, and for example, the self-luminous LED display screen can include LED lamp bead. Each light bead can emit light of one color, for example, a red light bead can only emit red light.
The self-luminous display screen comprises at least one first lamp bead and at least one second lamp bead, wherein the first lamp bead is a lighted lamp bead, and the second lamp bead is a extinguished lamp bead. Each first lamp bead is adjacent to eight lamp beads, namely an upper lamp bead, a lower lamp bead, a left lamp bead, a right lamp bead, an upper left lamp bead, an upper right lamp bead, a lower left lamp bead and a lower right lamp bead, and at least one extinguished second lamp bead is arranged in the adjacent lamp beads. Fig. 2 shows a schematic view of a lamp bead combination arrangement according to an embodiment of the present disclosure; fig. 3 shows another schematic diagram of a lamp bead combination arrangement mode according to the embodiment of the disclosure. As shown in fig. 2 and 3, any one of the lit lamp beads includes at least one of the extinguished lamp beads in the adjacent lamp beads. In addition to the lamp bead combination arrangement shown in fig. 2 and 3, any other lamp bead combination arrangement that can turn off at least one of the adjacent lamp beads of each lit first lamp bead may be adopted, which is not specifically limited by the present disclosure.
The self-luminous display screen can be shot by using the image acquisition device, and the image of the self-luminous display screen is acquired. The image obtained by shooting may be in any format, and format conversion may also be performed on the image flexibly according to actual needs, which is not limited in this disclosure.
In step S12, according to the image, first image data corresponding to the first lamp bead and second image data corresponding to the second lamp bead are obtained.
After acquiring an image obtained by shooting the self-luminous display screen, first image data corresponding to the first lamp bead and second image data corresponding to the second lamp bead may be acquired through a data processing device such as a computer. The first image data corresponding to the first lamp beads are measurement data representing the light-emitting characteristics of the first lamp beads, and include real data of the light-emitting characteristics of the first lamp beads and external environment light data. The second image data corresponding to the second lamp beads are measurement data representing the light-emitting characteristics of the second lamp beads, and the second lamp beads do not emit light, so that the second image data corresponding to the second lamp beads only represent external environment light data. The external environment light comprises other light in the shooting scene, such as sunlight, and can also comprise other light emitted by the first lamp bead.
In step S13, for the first image data corresponding to each first lamp bead, the first image data is corrected according to the second image data corresponding to the adjacent second lamp bead, so as to obtain third image data.
The third image data can be regarded as real data of the luminous characteristics of the first lamp beads, which are not influenced by the external environment light.
Therefore, the third image data of a part of lamp beads in the self-luminous display screen can be obtained by correcting all the first lamp beads which are currently lighted in the self-luminous display screen.
The calibration process will be described in detail later in conjunction with possible implementations of the present disclosure, and will not be described in detail here.
In step S14, after at least a portion of the second beads are lit, the steps of acquiring and following the image captured by the self-luminous display screen are re-executed until third image data of all beads in the self-luminous display screen is obtained.
After the third image data of a part of lamp beads in the self-luminous display screen is obtained, the lighting condition of the lamp beads in the self-luminous display screen can be adjusted. Specifically, the lit lamp beads in step S11 may be completely turned off or partially turned off, and the lit lamp beads are completely turned on or partially turned on, that is, all or part of the first lamp beads in step S11 is used as the adjusted second lamp beads, all or part of the second lamp beads in step S11 is used as the adjusted first lamp beads, and in the adjusted self-luminous display screen, at least one of the lit second lamp beads in adjacent lamp beads of each lit first lamp bead is controlled.
Further, based on the self-luminous display screen after adjustment, the above steps S11 to S13 are re-executed. After the steps are executed again, third image data of part or all of the lamp beads in the self-luminous display screen can be obtained.
And under the condition that third image data of part of the lamp beads in the self-luminous display screen are obtained, continuously adjusting the lighting condition of the lamp beads in the self-luminous display screen, and re-executing the steps S11 to S13 until the third image data of all the lamp beads in the self-luminous display screen are obtained.
In step S15, the self-luminous display screen is corrected according to the third image data of all the lamp beads.
Through correcting the first image data corresponding to the lamp beads, the influence of external environment light on the image data is reduced, the third image data corresponding to the lamp beads with higher accuracy can be obtained, the accuracy of correcting the self-luminous display screen based on the third image data of the lamp beads is effectively improved, and the correction effect of the self-luminous display screen is enhanced.
In one possible implementation, the self-luminous display includes at least one of the following: the display screen comprises a self-luminous LED display screen, a self-luminous OLED display screen, a self-luminous MicroLED display screen and a self-luminous MiniLED display screen.
The self-luminous display screen can be a self-luminous LED display screen, a self-luminous OLED display screen, a self-luminous MicroLED display screen, a self-luminous MiniLED display screen or other self-luminous display screens needing to be corrected.
In one possible implementation, the image data is used to indicate the chromaticity and/or brightness of the lamp bead.
The inconsistent attenuation of the whole self-luminous display screen can be embodied as different chromaticities and brightnesses of all lamp beads in the self-luminous display screen, so that compensation data required when the self-luminous display screen is corrected can be determined according to the chromaticities and/or the brightnesses of all the lamp beads in the self-luminous display screen.
In addition to chromaticity and brightness, the image data may also be used to indicate other attribute information of the lamp bead, which is not specifically limited by the present disclosure.
In one possible implementation, the image data includes at least CIE XYZ color space data.
In practical applications, the image data may be expressed by CIE XYZ color space coordinates of a color pattern proposed by the Commission Internationale de l' Eclairage (CIE), and the CIE XYZ color space coordinates may reflect chromaticity and luminance information. However, in the process of acquiring image data, it is not limited to using only CIE XYZ color space coordinates, and data of any color gamut conversion such as chromaticity space coordinates of three primary colors (RGB) may be used for processing, and this disclosure does not specifically limit this.
In a possible implementation manner, for first image data corresponding to each first lamp bead, correcting the first image data according to second image data corresponding to adjacent second lamp beads to obtain third image data, including: acquiring the mean value of second image data corresponding to second lamp beads adjacent to the first lamp beads; and determining third image data of the first lamp bead according to the difference between the first image data and the mean value.
Because in the self-luminous display screen, the interval between two adjacent lamp pearls is less, generally is several millimeters, then can be approximately think that two adjacent lamp pearls receive the influence of external environment light the same. That is, the external environment light data corresponding to the first lamp bead can be represented by the second image data corresponding to the second lamp bead adjacent to the first lamp bead. Under the condition that one first lamp bead is adjacent to two or more second lamp beads, the ambient light environment data of the first lamp bead can be represented by the mean value of the second image data corresponding to all the adjacent second lamp beads.
For a first lamp bead, the difference between the corresponding first image data and the mean value, namely the difference between the measurement data of the luminous characteristic of the first lamp bead and the external environment light data, represents the real data of the luminous characteristic of the first lamp bead.
Fig. 4 shows a schematic diagram of arrangement of lamp beads in a self-luminous display screen according to an embodiment of the disclosure. As shown in fig. 4, it is assumed that the self-luminous display includes 6 first light beads A, B, C, G, H, I and 6 second light beads D, E, F, J, K, L. Wherein, the first image data corresponding to the first lamp bead A can be represented as DAAnd the second lamp beads adjacent to the first lamp beads A are the second lamp beads D and the second lamp beads E. The second lamp bead D and the second lamp bead E respectively correspond to second image data DDAnd second image dataD E. The mean value of the second image data corresponding to the second lamp beads adjacent to the first lamp bead A is
Third image of first lamp bead AThe data can be expressed as
In a possible implementation manner, the third image data of each lamp bead is an average value of at least one third image data of the lamp bead.
Because the lighting condition of the lamp beads in the self-luminous display screen needs to be adjusted for multiple times, and the process of determining the third image data is executed again until the third image data of all the lamp beads in the self-luminous display screen is obtained, at least one third image data exists for one lamp bead. Then, the average value of at least one third image data may be used as the third image data of the lamp bead.
In addition, in practical application, the stability of the camera also influences the accuracy of the image data, in order to avoid the situation that the accuracy of the image data is low due to the stability problem of the camera, the self-luminous display screen can be shot for multiple times according to preset times, so that each lamp bead has at least one third image data, and then the average value of the at least one third image data is used as the third image data of the lamp bead. The preset times can be flexibly selected according to actual conditions, and the preset times are not particularly limited by the disclosure.
In a possible implementation manner, correcting the self-luminous display screen according to the third image data of all the lamp beads includes: and determining compensation data aiming at the self-luminous display screen according to the third image data of all the lamp beads, and correcting the self-luminous display screen based on the compensation data of the self-luminous display screen.
After the third image data of all the lamp beads in the self-luminous display screen are obtained, the compensation data of each lamp bead can be calculated by utilizing the third image data of all the lamp beads in the self-luminous display screen, and then the compensation data of the whole self-luminous display screen is obtained. And finishing the correction of the self-luminous display screen by utilizing the compensation data of the self-luminous display screen. The compensation data may be obtained by any method capable of determining the brightness compensation data of the self-luminous display screen in the related art, and the correction of the self-luminous display screen based on the compensation data of the self-luminous display screen may also be implemented based on the prior art, which is not specifically limited by the present disclosure.
