Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data processing, and in particular, to a method for determining display quality of a display and an electronic device. BACKGROUND

[0002] Currently, liquid crystal display devices on the market need a period of time from starting up to stable image display. This is caused by the cold light-emitting characteristics of liquid crystals and backlight power supplies. In the initial stage of power-on, especially in the case of cold start, the light-emitting and light-transmitting characteristics of the liquid crystal display device are in an unstable state. It takes a period of time to change from the unstable state to the stable state. The process generally does not exceed 20 minutes due to different device materials of liquid crystals and backlights. Meanwhile, the time required for hot start is shorter than that for cold start. In addition, the time required in summer is shorter than that in winter.

[0003] During this period, the display quality of the liquid crystal display device is inconsistent. In important application scenarios, users are reminded to avoid this period of time. However, in less stringent scenarios or in the case of civilian devices, users do not pay attention to this index, and they can accept the change from unstable images to stable images. For example, in the case of home televisions and commercial displays. However, as described above, in some important or special scenarios, this characteristic cannot be ignored. The instability of display image quality may cause user illusion. For example, in the case of medical displays or high-quality drawing displays, the instability of image quality may cause trouble for doctors or drafters.

[0004] In the prior art, the avoidance method is to require users to avoid using liquid crystal display devices during this unstable period and to wait until the display quality of images is stable before using the liquid crystal display devices. However, how to determine that the display quality of images is stable or how long to wait before using the liquid crystal display is determined by the user subjectively, so that the accuracy of determining the display quality of the display is low. SUMMARY

[0005] The present application relates to the technical field of data processing, and in particular, to a method for determining display quality of a display and an electronic device.

[0006] A first aspect of the present application provides a method for determining display quality of a display, the method comprising:

[0007] displaying a preset detection image in a specified area of the display after the display is powered on;

[0008] acquiring a gray-scale signal of the detection image in each color channel within a specified time interval every specified time interval;

[0009] obtaining a gray scale variation of each color channel based on the gray scale variations of the color channels;

[0010] obtaining the display quality of the display based on the gray scale variations of the color channels.

[0011] In the embodiment, the display quality of the display is automatically determined, and the user does not need to make subjective judgment, and the accuracy of determining the display quality of the display is improved.

[0012] In one embodiment, after the display quality of the display is obtained based on the gray scale variations of the color channels, the method further includes:

[0013] If it is determined that the display quality of the display is unstable, and the detection time length is less than a preset time length, returning to the step of obtaining the gray scale signals of the detection image in the specified time length in each color channel every specified time length until it is determined that the display quality of the display is stable or the detection time length is not less than the preset time length, wherein the detection time length is counted from when it is determined that the display is powered on.

[0014] If it is determined that the display quality of the display is unstable, and the detection time length is not less than the preset time length, prompting the user that the display is not working.

[0015] In the embodiment, when it is determined that the display quality of the display is unstable, and the detection time length is less than the preset time length, the display quality of the display needs to be detected again, so as to ensure the accuracy of the display quality.

In this way, the change amounts of the respective color channels determined are more accurate, and the display quality of the display is determined in combination with the change amounts of the respective color channels in this embodiment, further improving the accuracy of the display quality determined.

[0022] In one embodiment, the display quality of the display is obtained based on the gray scale change amounts of the respective color channels, including:

[0023] if the change amounts of the respective color channels are all less than a preset threshold, determining that the display quality of the display is stable; or

[0024] if at least one of the change amounts of the respective color channels is not less than the preset threshold, determining that the display quality of the display is unstable.

[0025] In this embodiment, the change amounts of the respective color channels are compared with the preset threshold respectively, and the display quality of the display is determined based on the comparison result. In this way, the accuracy of the display quality determined is ensured.

[0026] In one embodiment, after the display quality of the display is obtained based on the gray scale change amounts of the respective color channels, the method further includes:

[0027] if the display quality of the display is stable, prompting the user that the display quality of the display is normal.

[0028] In this embodiment, when it is determined that the display quality of the display is stable, the user is prompted that the display quality of the display is normal. In this way, the user does not need to make subjective judgments, and the use efficiency of the display is improved.

[0036] In an embodiment, the processor is further configured to:

[0037] after the display quality of the display is obtained based on the gray change amount of each color channel, if it is determined that the display quality of the display is unstable and a detection time length is less than a preset time length, returning to the step of acquiring, every specified time length, the gray signal of the detection image in each color channel within the specified time length until it is determined that the display quality of the display is stable or the detection time length is not less than the preset time length, wherein the detection time length is counted from when it is determined that the display is powered on;

[0038] if it is determined that the display quality of the display is unstable and the detection time length is not less than the preset time length, prompting a user that the display is invalid.

[0063] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, any other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.

[0064] In the embodiments of the present disclosure, the term “and / or” describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. The character “ / ” generally represents an “or” relationship between the associated objects before and after it.

[0065] The application scenarios described in the embodiments of the present disclosure are used to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. A person of ordinary skill in the art can know that as new application scenarios appear, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems. In the description of the present disclosure, unless otherwise specified, the meaning of “multiple” is two or more.

[0066] The display quality of liquid crystal display device is not consistent in a period of time after the power is turned on. But in the occasion of not strict or civil equipment, the user will not pay attention to this index, and they can accept the change process from unstable image to stable image, such as home television and commercial display. But for some important or special occasions as mentioned above, this characteristic cannot be ignored. The instability of display image quality may cause user illusion. For example, in medical display or high-quality drawing display, the instability of image quality may cause trouble for doctors or drafters. In the prior art, the display quality of the display is determined by the user subjectively, so that the accuracy of determining the display quality of the display is low.

[0067] Therefore, the present disclosure provides a method for determining the display quality of a display, which displays a pre-set detection image in a specified area of the display after the display is powered on, then determines the gray scale variation of each color channel by detecting the gray scale signals of each color channel of the detection image in the specified time period and the gray scale signals of each color channel of the detection image in the last specified time period, and finally determines the display quality of the display based on the variation, so that the display quality of the display can be automatically determined in this embodiment, without the need for user subjective judgment, and the accuracy of determining the display quality of the display is improved. The scheme of the present disclosure will be described in detail below with reference to the drawings.

[0068] As shown in Figure 1 , it is a structure diagram of the display, which includes a power supply circuit 110, a SOC master processor 120, a color sensor 130, a display driving circuit 140 and a display panel 150.

[0069] The power supply circuit 110 is used to supply power to the SOC master processor 120, the color sensor 130, the display driving circuit 140 and the display panel 150.

[0070] The color sensor 130 is used to detect the gray scale signals of each color channel of the detection image in the specified time period.

[0071] The SOC master processor 120 is used to obtain the gray scale signals of each color channel of the detection image in the specified time period detected by the color sensor 130 every specified time period; obtain the gray scale variation of each channel by using the gray scale signals of each color channel of the detection image in the specified time period and the gray scale signals of each color channel of the detection image in the last specified time period; obtain the display quality of the display based on the gray scale variation of each color channel, and then notify the display driving circuit 140 of the prompt information on the display panel 150.

[0072] The display driving circuit 140 is configured to receive instructions from the SOC host processor 120 and provide control signals in accordance with circuit logic as required by the display panel.

[0073] The display panel 150 is configured to display a preset detection image in a designated area.

[0074] As shown in Figure 2A , an application scenario provided by an embodiment of the present application is shown. The application scenario is described by taking an electronic device as a server as an example. The application scenario includes a server 210, a display 220, and a memory 230.

[0075] In a possible application scenario, after the display 220 is powered on, the server 210 obtains a preset detection image from the memory 230 and displays the preset detection image in a designated area of the display 220. Every specified time length, the server 210 obtains grayscale signals of the detection image in each color channel in the specified time length, and obtains grayscale variation of each channel by using the grayscale signals of the detection image in each color channel in the specified time length and grayscale signals of the detection image in each color channel in a previous specified time length. Then, the server 210 obtains display quality of the display based on the grayscale variation of each color channel, and displays the display quality of the display through the display 220.

[0076] As shown in Figure 2B , the application scenario includes a server 210 and a display 220. In a possible application scenario, after the display 220 is powered on, the server 210 obtains a preset detection image and displays the preset detection image in a designated area of the display 220. Every specified time length, the server 210 obtains grayscale signals of the detection image in each color channel in the specified time length, and obtains grayscale variation of each channel by using the grayscale signals of the detection image in each color channel in the specified time length and grayscale signals of the detection image in each color channel in a previous specified time length. Then, the server 210 obtains display quality of the display based on the grayscale variation of each color channel, and displays the display quality of the display through the display 220.

[0077] As shown in Figure 2CAs shown, the application scenario is described by taking the electronic device as an example. The application scenario includes the display 220 and the memory 230. In a possible application scenario, after the display 220 determines that it is powered on, the display 220 acquires a preset detection image and displays the preset detection image in a specified region. Every specified time length, the display 220 acquires the gray signals of the detection image in each color channel in the specified time length, and obtains the gray change amount of each channel by using the gray signals of the detection image in each color channel in the specified time length and the gray signals of the detection image in each color channel in the previous specified time length. Then, the display 220 obtains the display quality of the display based on the gray change amount of each color channel and displays the display quality.

[0078] wherein, Figure 2A and Figure 2B The server 210 and the display 220 in the application scenario can interact information through a communication network. The communication network can adopt a wireless communication mode or a wired communication mode.

[0079] For example, the server 210 can access the network through a cellular mobile communication technology and communicate with the display 220. The cellular mobile communication technology can include, for example, a 5th Generation Mobile Networks (5G) technology.

[0080] Optionally, the server 210 can access the network through a short-range wireless communication mode and communicate with the display 220. The short-range wireless communication mode can include, for example, a Wireless Fidelity (Wi-Fi) technology.

[0081] In addition, the description in the present application is only detailed for a single display 220, a single server 210, and a single memory 230. However, it should be understood by those skilled in the art that the display 220, the server 210, and the memory 230 shown are intended to represent the operations of the display 220, the server 210, and the memory 230 involved in the technical solution of the present application. It is not intended to limit the number, type, or location of the display 220, the server 210, and the memory 230. It should be noted that if additional modules are added to the illustrated environment or individual modules are removed therefrom, the underlying concept of the example embodiments of the present application will not change.

[0082] It should be noted that the method for determining the display quality of the display proposed in the present application is not only applicable to the application scenario shown in Figure 2A , Figure 2B and Figure 2C The method is also applicable to any device for determining the display quality of the display.

[0083] The method for determining display quality of a display according to the present application will be described below in combination with the above-described application scenarios and with reference to the accompanying drawings. It should be noted that the above-described application scenarios are only shown for the purpose of facilitating the understanding of the method and principles of the present application, and the embodiments of the present application are not limited in this respect.

[0084] As shown in FIG. 1, a flowchart of the method for determining display quality of a display according to the present application can include the following steps: Figure 3

[0085] Step 301: After the display is powered on, a pre-set detection image is displayed in a specified area of the display;

[0086] For example, as shown in FIG. 2, a schematic diagram of the specified area of the display, Figure 4 Figure 4 In the embodiment shown in FIG. 2, the specified area is arranged at the lower right of the display area. In the embodiment, the color sensor in the display is installed at a specific angle in the frame of the display, and the light-sensitive area of the color sensor faces the position of the specified area of the display, and an optical access gap is left between the specified area and the color sensor to keep the light unobstructed.

[0087] It should be noted that: Figure 4 The position of the specified area of the display in the embodiment is only used for illustration and does not limit the position of the specified area of the display. In the embodiment, the position of the specified area of the display can be set according to actual conditions, for example, any one of the four corners or any position of the display, and the present embodiment does not limit the position of the specified area of the display.

[0088] In addition, in order to ensure color consistency and focusing of the color sensor, the size of the specified area should be as large as possible in principle. However, a small block will occupy less display space, and other display space can be used by the SOC main processor. Therefore, the size of the specified area should be no less than 20mm*20mm. However, the size of the specified area can be set according to actual conditions, and the present embodiment does not limit the size of the specified area.

[0089] In addition, the color sensor in the embodiment can be an RGB sensor or any other sensor capable of recognizing changes in display light flux, and the present embodiment does not limit the color sensor.

[0090] Step 302: Every specified time interval, the gray-scale signals of the detection image in each color channel within the specified time interval are obtained;

[0091] In the embodiment, the specified time interval can be set according to actual conditions, and the present embodiment does not limit the specified time interval. In the embodiment, the specified time interval can be set according to actual conditions, and the present embodiment does not limit the specified time interval.​

[0092] Step 303: obtaining a gray scale variation of each channel by using the gray scale signal of each color channel of the detection image in the specified time length and the gray scale signal of each color channel of the detection image in the previous specified time length;

[0093] The color channels include an R channel, a G channel and a B channel.

[0094] In an embodiment, step 303 can be implemented as:

[0095] (1) subtracting the gray scale signal of the R channel of the detection image in the previous specified time length from the gray scale signal of the R channel of the detection image in the specified time length to obtain the variation of the R channel. The variation of the R channel can be obtained by formula (1):

[0096] ΔR = R - R' … (1);

[0097] wherein ΔR is the variation of the R channel, R is the gray scale signal of the R channel of the detection image in the specified time length, and R' is the gray scale signal of the R channel of the detection image in the previous specified time length.

[0098] (2) subtracting the gray scale signal of the G channel of the detection image in the previous specified time length from the gray scale signal of the G channel of the detection image in the specified time length to obtain the variation of the G channel. The variation of the G channel can be obtained by formula (2):

[0099] ΔG = G - G' … (2);

[0100] wherein ΔG is the variation of the G channel, G is the gray scale signal of the G channel of the detection image in the specified time length, and G' is the gray scale signal of the G channel of the detection image in the previous specified time length.

[0101] (3) subtracting the gray scale signal of the B channel of the detection image in the previous specified time length from the gray scale signal of the B channel of the detection image in the specified time length to obtain the variation of the B channel. The variation of the B channel can be obtained by formula (3):

[0102] ΔB = B - B' … (3);

[0103] wherein ΔB is the variation of the B channel, B is the gray scale signal of the B channel of the detection image in the specified time length, and B' is the gray scale signal of the B channel of the detection image in the previous specified time length.

[0104] Step 304: obtaining the display quality of the display based on the gray scale variations of the color channels.

[0105] Thus, in the present application, after determining that the display is powered on, a preset detection image is displayed in a specified area of the display, then the gray scale variation of each color channel is determined based on the gray scale signal of each color channel within the specified time duration and the gray scale signal of each color channel within the previous specified time duration, and finally the display quality of the display is determined based on the variation, so that the display quality of the display can be automatically determined without the subjective judgment of the user, and the accuracy of determining the display quality of the display is improved.

[0106] In one embodiment, as shown in FIG. 8, which is a specific flowchart for determining the display quality of the display, the following steps are included: Figure 5

[0107] Step 501: Determine whether the variation of each color channel is less than a preset threshold value, if yes, execute step 502, if no, execute step 503.

[0108] In the present embodiment, the preset threshold value is 1%, but the preset threshold value can be set according to the actual situation, which is not limited in the present embodiment.

[0109] Step 502: Determine that the display quality of the display is stable.

[0110] Step 503: Determine that the display quality of the display is unstable.

[0111] In order to improve the accuracy of determining the display quality of the display, in one embodiment, after step 304 is executed, the following three cases can be included:

[0112] Case 1: If it is determined that the display quality of the display is stable, prompt the user that the display quality of the display is normal.

[0113] For example, as shown in FIG. 9, which is a terminal interface diagram, the user is prompted that the display quality of the display is normal and can use it with confidence. Figure 6

[0114] Case 2: If it is determined that the display quality of the display is unstable and the detection time duration is less than a preset time duration, return to the step of acquiring the gray scale signal of each color channel within the specified time duration every specified time duration until it is determined that the display quality of the display is stable or the detection time duration is not less than the preset time duration, wherein the detection time duration is counted from the time when it is determined that the display is powered on.

[0115] Case 3: If it is determined that the display quality of the display is unstable and the detection time duration is not less than the preset time duration, prompt the user that the display of the display is invalid.

[0116] For example, as shown in FIG. 10, which is a terminal interface diagram, the user is prompted that the display of the display is invalid.​​Figure 7 As shown, it is a terminal interface schematic diagram, which prompts the user that the display of the display is invalid, so as to remind the user to troubleshoot.

[0117] In order to further understand the technical solutions of the present disclosure, the following will be combined with Figure 8 Detailed description can include the following steps:

[0118] Step 801: determining to display a preset detection image in a specified area of the display after the display is powered on;

[0119] Step 802: acquiring the gray signals of the detection image in each color channel within a specified time interval, wherein the color channels include R channel, G channel and B channel;

[0120] Step 803: subtracting the gray signal of the detection image in R channel within the specified time interval from the gray signal of the detection image in R channel within the last specified time interval to obtain the change amount of R channel;

[0121] Step 804: subtracting the gray signal of the detection image in G channel within the specified time interval from the gray signal of the detection image in G channel within the last specified time interval to obtain the change amount of G channel;

[0122] Step 805: subtracting the gray signal of the detection image in B channel within the specified time interval from the gray signal of the detection image in B channel within the last specified time interval to obtain the change amount of B channel;

[0123] Step 806: determining whether R channel, B channel and G channel are all less than a preset threshold, if yes, executing step 807, if not, executing step 808;

[0124] Step 807: determining that the display quality of the display is stable;

[0125] Step 808: determining that the display quality of the display is unstable;

[0126] Step 809: determining whether the detection time interval is less than a preset time interval, if yes, returning to execute steps 803, 804 and 805, if not, executing step 810;

[0127] Step 810: prompting the user that the display of the display is invalid.

[0128] Based on the same disclosure concept, the method for determining the display quality of the display as described above can also be realized by a method device for determining the display quality of the display. The effect of the method device for determining the display quality of the display is similar to that of the foregoing method, which will not be repeated here.
