Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. The claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a screen testing method for testing the flicker value of a target screen, and the specific flow is shown in fig. 1, and the method comprises the following steps:
Step S101: the target screen is divided into N display areas.
Specifically, in this step, the target screen may be divided into N display areas according to different division standards according to actual needs. For example, fig. 2 shows an example of a specific divided display area in the present embodiment, and in fig. 2, the target screen is divided into N display areas 20 arranged in an array, where N is a positive integer, that is, the target screen is divided by using dividing lines that are disposed perpendicular to each other. The partitioning method shown in fig. 2 is highly versatile and simple in process flow. In addition, as shown in fig. 3, the display area may be divided according to the driving circuit to which the light emitting pixel units are connected, that is, the light emitting pixel units belonging to the same driving circuit may be divided into one display area 20. In the division method shown in fig. 3, since the pixel units in the same display area belong to the same driving circuit, the driving circuits in the respective display areas can be adjusted to reduce the flicker value after the flicker value measurement is completed.
It should be understood that the foregoing description is merely illustrative of two specific screen dividing methods according to the present invention, and is not limited thereto, and in other embodiments of the present invention, other methods, such as dividing according to functions of each area of the target screen (transparent display area, non-transparent display area, etc.), may be adopted, and in particular, flexible selection may be performed according to actual needs.
Step S102: m screen images of a target screen are acquired.
Specifically, in this step, the target screen is first lighted, and then the lighted target screen is continuously photographed at a high speed using an imaging device such as a CCD (charge coupled device ) camera, so that M sub-screen images are obtained, where M is a positive integer greater than 1.
Step S103: luminance fluctuation images of the respective display areas are acquired.
In this step, luminance fluctuation images of the respective display areas are acquired according to luminance changes of the respective display areas in the M screen images, wherein each display area corresponds to one luminance fluctuation image. That is, each display area corresponds to one luminance in each screen image, that is, each display area has M display luminances, as shown in fig. 4, for any one display area, the M screen images may be numbered according to the photographing time sequence and then used as a horizontal axis, the display luminances of the display areas are used as a vertical axis to construct a rectangular coordinate system, and the M display luminances of each display area are filled into the rectangular coordinate system, so that a luminance fluctuation image corresponding to each display area can be obtained. The N display areas can correspondingly acquire N brightness fluctuation images.
Step S104: and obtaining the flicker value of each display area according to the brightness fluctuation image.
Specifically, in the present embodiment, the process of acquiring the flicker value from the luminance fluctuation image for each display area is independent from each other, and the luminance fluctuation image for each display area may be acquired one by one as the sampling luminance fluctuation image. It will be appreciated that the prior art computer technology has enabled multi-threaded parallel processing of data, and thus the foregoing acquisition of the luminance fluctuation image of each display area one by one as a sampling luminance fluctuation image is not limited to the acquisition of the luminance fluctuation image of one display area at a time as a sampling luminance fluctuation image, but rather the acquisition of the flicker value of each display area takes its corresponding luminance fluctuation image as a sampling luminance fluctuation image.
Preferably, in an embodiment of the present invention, at least two display areas may be acquired as sampling display areas according to the need, and then the luminance fluctuation image of each sampling display area may be acquired as a sampling luminance fluctuation image. That is, when calculating the flicker value, the flicker value of a part of the display area is calculated according to actual needs, so that the calculated amount can be effectively reduced, and the calculation speed can be improved.
In this embodiment, the specific step of acquiring the flicker value of the display region from the sampled luminance fluctuation image is as shown in fig. 5, and includes the steps of:
Step S201: and inputting the sampling brightness fluctuation image into a spectrum analyzer, and obtaining sampling energy data of a display area corresponding to the sampling brightness fluctuation image, which is output by the spectrum analyzer.
Specifically, in this step, the sampled luminance fluctuation image shown in fig. 4 is input into a spectrum analyzer for spectrum analysis, and the spectrum analyzer outputs an analysis result after spectrum analysis of the sampled luminance fluctuation image, where the analysis result is the sampled energy data of the display area corresponding to the sampled luminance fluctuation image. The sampled energy data includes R luminance fluctuation frequencies and energy values corresponding to the luminance fluctuation frequencies one by one as shown in fig. 6, where R is a positive integer.
Step S202: and obtaining the flicker value of the display area corresponding to the sampling energy data according to the sampling energy data.
Specifically, in this step, first, human eye sensitivity coefficients corresponding to each brightness fluctuation frequency one by one need to be obtained, as shown in fig. 7, which shows a specific human eye sensitivity coefficient table, where each brightness fluctuation frequency corresponds to a specific human eye sensitivity coefficient. Then, the flicker value of the display area corresponding to the sampling energy data can be obtained according to the brightness fluctuation frequency and the human eye sensitivity coefficient. For example, the human eye sensitivity coefficient corresponding to each brightness fluctuation frequency and the energy value corresponding to each brightness fluctuation frequency in the sampling energy data can be multiplied to obtain products corresponding to each brightness fluctuation frequency as scintillation parameters, namely R scintillation parameters can be obtained, and then the maximum value in the R scintillation parameters is obtained as a target scintillation parameter; and obtaining the logarithm of the target flicker parameter to obtain a flicker value. The calculation formula is used for expressing as: y=10log (P X/P0), where Y is the flicker value, P X is the target flicker parameter, and P 0 is the preset constant.
Alternatively, in the present embodiment, the maximum value of the calculated flicker values of the respective display regions may be used as the flicker value of the entire display screen. It should be understood that the maximum value of the flicker value of each display area is merely a specific example of the whole display screen, and is not limited to this embodiment, and in other embodiments of the present invention, the minimum value of the flicker value of each display area, or the average value of the flicker values of each display area, or other calculation methods, for example, the result obtained by differential calculation is taken as the flicker value of the whole display screen, and specifically, the setting may be flexibly performed according to actual needs.

The screen types can be various including a liquid crystal screen, an LED screen, an OLED screen and the like, or OLED screens of different types, liquid crystal screens of different types and the like, and particularly can be flexibly set according to actual needs.
Step S305: and acquiring a human eye sensitive coefficient table corresponding to the screen type sent by the server.
Specifically, in this embodiment, after receiving the update request, the server may search for and obtain the latest human eye sensitivity coefficient table corresponding to the target screen from the internet, and then send the latest human eye sensitivity coefficient table to the screen test device, where after receiving the human eye sensitivity coefficient table sent by the server, the screen test device updates the originally stored human eye sensitivity coefficient table according to the newly received human eye sensitivity coefficient table.
