In the production process of various display screens such as self-luminous LED/OLED/micro LED/MiniLED display screens, the material process, the production packaging process and the like of the lamp beads can cause different attenuation degrees of the lamp beads in the self-luminous LED/OLED/micro LED/MiniLED display screens, so that the condition of inconsistent attenuation of the whole screen occurs in the use process. Therefore, correction is often required for the self-luminous display screen point by point before delivery of the self-luminous display screen. In the related art, it is generally required to photograph a self-luminous display screen, determine compensation data of each lamp bead according to image data of each lamp bead, and then correct the self-luminous display screen. However, in this process, the image data of the lamp beads may be affected by the external ambient light, especially, since the photographing exposure time is long, the external ambient light is difficult to keep stable, which results in lower accuracy of the compensation data obtained according to the image data of the lamp beads, and affects the correction effect on the self-luminous display screen.
The embodiment of the disclosure 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 lighted, at least one second lamp bead is extinguished, at least one second lamp bead in adjacent lamp beads of each lighted first lamp bead is extinguished, an image obtained by shooting the self-luminous display screen is obtained, first image data corresponding to the first lamp bead and second image data corresponding to the second lamp bead are obtained according to the image, further, the first image data is corrected according to the second image data corresponding to the adjacent second lamp beads for each first image data corresponding to obtain third image data, and after at least part of the second lamp beads are lighted, the steps of obtaining the image obtained by shooting the self-luminous display screen and the following steps are re-executed until the third image data of all the lamp beads in the self-luminous display screen are obtained. By correcting the first image data corresponding to the first lamp beads according to the second image data corresponding to the second lamp beads, third image data with higher accuracy can be obtained, and then when the self-luminous display screen is corrected based on the third image data, the influence of variable ambient light can be reduced, and the correction effect of the self-luminous display screen is effectively enhanced.
Fig. 1 shows a flowchart of a self-luminous display screen correction method according to an embodiment of the present disclosure. As shown in fig. 1, the self-luminous display screen correction method may include:
in step S11, an image obtained by photographing the self-luminous display screen is obtained, wherein at least one first bead in the self-luminous display screen is turned on, at least one second bead is turned off, and at least one turned-off second bead is located in an adjacent bead of each turned-on first bead.
The self-luminous display screen is formed by combining and arranging lamp beads, for example, the self-luminous LED display screen can comprise LED lamp beads. Each bead may emit light of one color, e.g., a red bead may only emit light of red color.
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. Wherein, every first lamp pearl is adjacent with upper, lower, left, right, upper left, upper right, lower left, lower right eight lamp pearls, in the adjacent lamp pearl, has at least one second lamp pearl that goes out. FIG. 2 illustrates a schematic diagram of a bead pack arrangement in accordance with an embodiment of the present disclosure; fig. 3 illustrates another bead pack arrangement according to an embodiment of the present disclosure. As shown in fig. 2 and 3, any one of the lighted beads, at least one of the adjacent beads, which is turned off, is included. In addition to the bead combination arrangement shown in fig. 2 and 3, any other bead combination arrangement that can cause at least one of the second beads to be extinguished in the adjacent beads of each first bead that is lit may be used, which is not particularly limited in this 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 captured image may be in any format, or may be flexibly converted according to actual needs, which is not specifically limited in the present 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 the image obtained by shooting the self-luminous display screen is obtained, the first image data corresponding to the first lamp bead and the second image data corresponding to the second lamp bead can be obtained through a data processing device such as a computer. The first image data corresponding to the first lamp beads are measurement data representing the luminous characteristics of the first lamp beads, and the measurement data comprise real data of the luminous 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 luminous 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 ambient light includes other light in the photographed scene, such as sunlight, and may also include other light emitted from the first beads.
In step S13, for the first image data corresponding to each first bead, the first image data is corrected according to the second image data corresponding to the adjacent second beads, so as to obtain third image data.
The third image data may be regarded as real data of the light emission characteristics of the first lamp beads, which are not affected by the external ambient light.
In this way, the third image data of a part of the 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 correction process will be described in detail in connection with possible implementations of the present disclosure, and will not be described here.
In step S14, after at least part of the second beads are turned on, the steps of acquiring the image obtained by photographing the self-luminous display screen and thereafter are re-performed until the third image data of all the beads in the self-luminous display screen are obtained.
After the third image data of a part of the 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 light-up beads in the step S11 may be all turned off, or partially turned off, and the turned-off beads may be all turned on, or partially turned on, that is, all or part of the first beads in the step S11 are used as the adjusted second beads, all or part of the second beads in the step S11 are used as the adjusted first beads, and at least one turned-off second bead in adjacent beads of each light-up first bead in the adjusted self-luminous display screen is controlled.
Further, the above steps S11 to S13 are re-executed based on the self-luminous display panel after adjustment. After the steps are re-executed, the third image data of part or all of the lamp beads of the self-luminous display screen can be obtained.
In the case of obtaining the third image data of a part of the beads in the self-luminous display screen, the lighting condition of the beads in the self-luminous display screen can be continuously adjusted, and the above steps S11 to S13 are repeatedly performed until the third image data of all the beads in the self-luminous display screen is obtained.
In step S15, the self-luminous display screen is corrected according to the third image data of all the lamp beads.
By 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 screen includes at least one of: the display comprises a self-luminous LED display screen, a self-luminous OLED display screen, a self-luminous micro LED 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 micro LED display screen, a self-luminous MiniLED display screen or other self-luminous display screens needing correction.
In one possible implementation, the image data is used to indicate the chromaticity and/or brightness of the beads.
The inconsistent attenuation of the whole self-luminous display screen can be reflected by different chromaticity and brightness of each lamp bead in the self-luminous display screen, so that compensation data required for correcting the self-luminous display screen can be determined according to the chromaticity and/or brightness of each lamp bead in the self-luminous display screen.
In addition to chromaticity and luminance, the image data may be used for other attribute information of the indicator beads, which is not particularly limited in this disclosure.
In one possible implementation, the image data includes at least CIE XYZ color space data.
In practice, the image data may be represented by the color pattern CIE XYZ color space coordinates proposed by the international commission on illumination (Commission Internationale de l' Eclairage, CIE), which may reflect chromaticity and luminance information. However, the process of acquiring image data is not limited to the CIE XYZ color space coordinates, and may be performed using any color gamut converted data such as chromaticity space coordinates of three primary colors (RGB), which is not particularly limited in the present disclosure.
In one possible implementation manner, for the first image data corresponding to each first bead, correcting the first image data according to the second image data corresponding to the adjacent second beads to obtain third image data, including: acquiring the average 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 beads according to the difference between the first image data and the mean value.
Because in the self-luminous display screen, the distance between two adjacent lamp beads is smaller, generally a few millimeters, the two adjacent lamp beads can be approximately considered to be affected by the same external environment light. The second image data corresponding to the second lamp bead adjacent to the first lamp bead can be used for representing the external environment light data corresponding to the first lamp bead. When one first lamp bead is adjacent to two or more second lamp beads, the average value of the second image data corresponding to all the adjacent second lamp beads can be used for representing the external light environment data of the first lamp bead.
For a first lamp bead, the difference between the corresponding first image data and the average value, namely the difference between the measured 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 is a schematic view showing an arrangement of light beads in a self-luminous display screen according to an embodiment of the present disclosure. As shown in fig. 4, it is assumed that the self-luminous display screen includes 6 first beads A, B, C, G, H, I and 6 second beads D, E, F, J, K, L. Wherein the first image data corresponding to the first lamp bead A can be expressed as D A The second lamp beads adjacent to the first lamp bead A are a second lamp bead D and a second lamp bead E. The second lamp bead D and the second lamp bead E respectively correspond to the second image data D D And second image data D E . The average value of the second image data corresponding to the second lamp beads adjacent to the first lamp bead A isThe third image data of the first lamp bead A can be expressed as +.>
In one possible implementation, the third image data for each bead is a mean of at least one third image data for that bead.
Since the lighting condition of the lamp beads in the self-luminous display screen needs to be adjusted for a plurality of times, and the process of determining the third image data is re-executed until the third image data of all the lamp beads in the self-luminous display screen are obtained, at least one third image data is provided for one lamp bead. Then, the mean value of the 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 affects the accuracy of the image data, in order to avoid the situation that the accuracy of the image data is lower due to the stability problem of the camera, the self-luminous display screen can be photographed 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 method is not particularly limited.
In one possible implementation, correcting the self-luminous display screen according to the third image data of all the beads includes: and determining compensation data for 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 using the third image data of all the lamp beads in the self-luminous display screen, so that the compensation data of the whole self-luminous display screen can be obtained. And correcting the self-luminous display screen by using the compensation data of the self-luminous display screen. The compensation data may be obtained by any manner in the related art capable of determining the brightness compensation data of the self-luminous display screen, and based on the compensation data of the self-luminous display screen, the correction of the self-luminous display screen may also be implemented based on the prior art, which is not specifically limited in the present disclosure.
