Abstract
The application relates to a display screen blind test detection method, a concentration evaluation method and a point screen device. The method comprises the following steps: randomly determining whether a blind test detection mode is started currently according to a preset second blind test rate, wherein the second blind test rate indicates the probability of starting the blind test detection mode currently; randomly extracting N reference images from a plurality of reference images to be transmitted as first reference images under the condition that the blind detection mode is determined to be started, wherein N is a natural number; generating N blind test images corresponding to each other one by one based on the N reference images, wherein the blind test images are used for simulating display abnormality of a display screen; and sending the plurality of reference images and the N blind test images to the display screen.
Description
The application is a divisional application of application with application date 2023, 02-03, china application number 202310053473.7 and the name of 'display screen blind detection method, point screen device and storage medium', and the whole content of the original application is incorporated by reference.
Technical Field
The application relates to the technical field of display screen point screen detection, in particular to a display screen blind detection method, a concentration evaluation method and point screen equipment.
Background
Before the display screen leaves the factory, the operator needs to carry out screen pointing detection on the semi-finished display screen. One solution is to send a series of standard images to the display screen through the dot screen device to display on the display screen, and the operator judges whether there is an abnormality such as a defective dot, a defective line or Mura (uneven brightness of the display) by observing the condition of the images displayed on the display screen. If there is an abnormality, the defective panel needs to be reworked. The detection flow requires that the operator be in a concentrated state for a long time. Therefore, the display abnormality of the current display screen is always generated, but the operator is not focused to cause missed detection.
In this regard, chinese patent publication No. CN105301001a discloses a blind test technique, which adds a blind test image with a defect in the test process to check whether an operator can detect the defect, so as to determine whether the operator is focused.
However, in the technical solutions disclosed in the above patent documents, at least the following drawbacks exist:
1. in the prior art, corresponding blind test images (special blind test patterns) are edited in an upper computer one by one according to reference images (conventional test patterns). In the production process, if the reference image is changed, the blind test image is required to be synchronously changed to be supported, so that the timeliness is poor.
2. In the prior art, a conventional reference image needs to be replaced by a blind test image, and after the replacement, the defect of the blind test image has the probability of covering the defect of the display screen itself (for example, if the position of a black line for simulating an abnormality on the blind test image is just the dead pixel position of the display screen, the real dead pixel of the display screen cannot be judged). In the above patent document, after the blind test is finished, only the attention of the operator is detected, and after the actual dead pixel on the screen is covered by the blind test image, the inspector cannot see the actual dead pixel, thereby causing missed detection. If the blind test result is reported to the MES (production process execution management system server), the whole is rechecked by the reference image again to confirm whether the display screen has display defects or not, the operation time is increased, and the detection efficiency is reduced.
3. In the prior art, a blind test result settlement interface is displayed after all the current patterns are switched, and an operator fills in test contents by virtue of memory, so that the situation of error recording aiming at the defect position and type result of the blind test image is possible.
4. Once the blind test image in the prior art is edited, the defect position of the blind test image is relatively fixed. After multiple tests, operators can clearly know the blind test images and the defect simulation positions of the blind test images, and the effects of checking the attention of the operators and reducing the omission ratio are difficult to achieve.
5. In the prior art, when whether the blind test mode needs to be started or not is confirmed, the blind test mode can be started only through interaction with a client MES system, the starting is notified through the MES system, and if part of clients do not need to be connected with the MES, the function cannot be used.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. It will be apparent that the described embodiments are some, but not all, embodiments of the application. All other embodiments, which can be made by a person skilled in the art without creative efforts, based on the described embodiments of the present application fall within the protection scope of the present application. It is to be understood that some of the technical means of the various embodiments described herein may be interchanged or combined without conflict.
In the description of the present specification and claims, the terms "first," "second," and the like, if any, are used merely to distinguish between the described objects and do not have any sequential or technical meaning. Thus, an object defining "first," "second," etc. may explicitly or implicitly include one or more such objects. Also, the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one.
As shown in fig. 1, a flowchart of a method for detecting blind detection of a display screen according to an embodiment of the present application may be applied to a dot screen device, that is, the method for detecting blind detection may be executed by each hardware portion of the dot screen device in combination with a corresponding software program. The method comprises the following steps:
s101, sending a first blind test image to a display screen to enable the display screen to display the first blind test image, wherein the first blind test image is obtained by adding a first abnormal simulation pattern to a random part of a first reference image, and the first abnormal simulation pattern is used for simulating that a display abnormality exists in a part of the display screen corresponding to the random part;
s102, acquiring feedback information of an operator aiming at the first blind test image, wherein the feedback information indicates whether the operator judges that a first abnormal simulation graph exists on the first blind test image;
and S103, sending the first reference image to a display screen so that the display screen displays the first reference image.
It can be understood that the first reference image is a normal dot screen image (such as a pure red image, a pure blue image, a stripe image between red and white, or a landscape image) provided by the dot screen device, and if the display performance of the tested display screen is normal, the standard first reference image is completely presented on the display screen; if the display performance of the display screen to be tested is abnormal, the display screen cannot completely display the standard first reference image, for example, the display screen has dark spots at corresponding positions of the first reference image displayed on the display screen due to the damage of the luminous pixel points of a certain area of the display screen.
The first abnormal simulation pattern is a pattern which is actively added to the original normal first reference image by the dot screen device, and the first abnormal simulation pattern is used for replacing the normal pattern coverage of the corresponding area on the first reference image. When the first blind test image with the first abnormal simulation pattern is displayed by the display screen, the presented first abnormal simulation pattern can virtually represent (rather than truly reflect) the fault type of the corresponding position on the display screen, however, a detector (hereinafter referred to as an industrial personnel) judging whether the display screen has a display fault by visually observing (or checking with a tool) whether the display screen is abnormal or not does not know that the display effect of the first abnormal pattern is a real effect or a virtual effect, and only judges whether the corresponding display fault type exists according to the observed display screen, but the point-screen device with a hardware circuit and a software code can know the simulation information. Therefore, if the operator can accurately indicate the simulated display fault type when or after the first blind test image is displayed on the display screen, the operator is indicated to have better concentration; if the operator can not accurately indicate the simulated display fault type when or after the first blind test image is displayed on the display screen, the concentration is not concentrated.
It should be noted that, in general, the dot screen device sends a plurality of images with different display effects to the display screen sequentially, so as to fully show the display performance of the display screen as much as possible. In case the first reference image is not reiterated after the transmission of the first blind test image evolved from the first reference image, there may be a problem that:
although the first blind test image has part of the content of the first reference image, the first blind test image is not completely presented for the first reference image, so that the display panel cannot well show the display performance which can be shown by the first reference image. More seriously, if the display screen originally has a display defect at the position of the first blind test model, especially the position of the first abnormal simulation graph, and the display defect can be obviously expressed only when the first reference image is displayed, the display screen cannot find out the corresponding defect of the display screen due to the lack of the first reference image. For example, assuming that a display screen has a defective pixel at its center portion and cannot normally display an ideal color, and that color abnormality exhibited by the center portion is most prominent when the display screen displays a first reference image, it is coincided that in step S301, the first abnormality simulation pattern is just randomly added to the center portion of the first blind test image, in which case, if the display screen does not complement the first reference image after displaying the first blind test image for testing the concentration of an operator instead of actually detecting the display performance of the display screen, there is a high possibility that the problem that the defective pixel at the center portion of the display screen cannot be found finally, and thus the display screen having a display failure flows to the market is caused. Advantageously, the embodiment of the application supplements the original first reference image after sending the first blind test image for testing the concentration degree of the operator instead of truly detecting the display performance of the display screen to the display screen, thereby reducing the possibility of missed detection.
In addition, the part of the first abnormal simulation pattern added on the first reference image is random and not fixed all the time, so that the condition that the experienced operator easily knows that the first blind test image is a fault simulation image, the position of the first abnormal simulation pattern and the display abnormal type of the first abnormal simulation pattern simulation can be effectively avoided.
In some embodiments, the examiner may store in advance in the memory of the dot screen apparatus a plurality of types of abnormality simulation patterns, such as an abnormality dot pattern for simulating the presence of a pixel point displaying an abnormality on the display screen, an abnormality line pattern for simulating the presence of a line area displaying an abnormality on the display screen, a MURA pattern for simulating the presence of display unevenness (MURA abnormality) in the relevant portion of the display screen, the plurality of types of abnormality simulation patterns constituting an abnormality simulation pattern library, the aforementioned first abnormality simulation pattern being one type of abnormality simulation pattern randomly extracted from the abnormality simulation pattern library. In this way, the likelihood of this occurrence can be further reduced: the experienced operator easily knows that the first blind test image is a fault simulation image which is penetrated and the display abnormality type of the first abnormality simulation graph simulation.
Obviously, the foregoing outlier pattern, and MURA pattern may each include multiple sub-types, and for example, the outlier pattern may include outlier arcs, outlier lines, outlier fold lines, and the like.
If the feedback of the operator to the first blind test image is not examined immediately after the first blind test image is transmitted, but the first reference image is directly reissued, and after the first reference image is reissued, the feedback of the operator to the first blind test image is collected, there may be a problem that: after the operator examines the first blind test image, the operator also continuously examines at least one other image including the first reference image, so that the visual impression of the operator on the first blind test image is blurred, and the feedback information about the first blind test image is caused to have deviation which is not caused by insufficient concentration. Furthermore, more seriously, the operator is likely to confuse his impression of the first blind test image with the impression of the first reference image when giving feedback information.
In contrast, in the present embodiment shown in fig. 1, step S102 is further performed after S101 and before S103: and acquiring feedback information of the operator aiming at the first blind test image.
After the point screen device sends the first blind test image to the display screen, the point screen device does not pay attention to the display screen to send the first reference image, but confirms that the feedback information of the operator on the first blind test image is received, so as to know whether the operator judges that the first abnormal simulation graph exists on the first blind test image or not, and then sends the first reference image. In this way, the operator's impression of the first blind test image can be reduced from blurring.
In other embodiments, step S102 further requires: the feedback information indicates that the operator determines that the first abnormal simulation pattern exists on the first blind test image, that is, the dot screen device needs to send the first reference image after confirming that the operator has accurately determined that the first abnormal simulation pattern exists on the first blind test image. In this way, the operator can be further allowed to perform subsequent detection work under the condition that the concentration of the operator is confirmed to be sufficiently concentrated, and the false detection rate is reduced.
In the embodiment described in the previous paragraph, in case the point screen device fails to receive the desired feedback information within a predetermined time period, for example, the actual feedback information given by the operator for a predetermined time period does not correspond to the desired feedback information, the sending of the first reference image may be stopped, and the method may be stopped, or the operator may be allowed to re-enter the feedback information until it is correct.
In order to determine the concentration of the operator more accurately, in the embodiment described in the previous paragraph, step S102 may further require: the feedback information indicates the operator to judge that the first abnormal simulation pattern exists in the random part of the first blind test image. That is, the operator needs to not only point out the display failure type corresponding to the first abnormal simulation pattern, but also accurately point out the position of the first abnormal simulation pattern in the first blind test image (display screen) and then reissue the first reference image.
Referring back to fig. 1, in the embodiment shown in fig. 1, even if the feedback information indicates that the operator has not successfully determined that the first abnormal simulation pattern exists in the random portion of the first blind test image, step S103 is still performed. Further, after step S103, the method further includes:
and S104, based on the feedback information, evaluating the concentration of the operator.
In combination with the above description, if the operator can accurately indicate the simulated display fault type and fault location when or after the first blind test image is displayed on the display screen, the operator is illustrated to have better concentration; if the operator can not accurately indicate the simulated display fault type and fault position when or after the first blind test image is displayed on the display screen, the concentration is not concentrated. Therefore, the concentration of the worker can be evaluated based on the feedback information.
In order to guide the operator to perform the above input operation, referring to fig. 2, in some embodiments, before acquiring the feedback information of the operator, that is, before step S102, the screen pointing method further includes:
s105, sending an interactive interface to the second display screen so that the second display screen displays the interactive interface, wherein the interactive interface comprises an abnormal type selection area and an abnormal position selection area.
The second display screen may be the same display screen as the aforementioned display screen (i.e., the display screen to be tested), or may be two different display screens, for example, the second display screen is a display screen of the pointing device.
In the embodiment shown in fig. 2, the feedback information in step S102 thereof includes a selection result of the abnormality type selection area and a selection result of the abnormality position selection area.
Illustratively, after the point screen device sends the interactive interface to the second display screen, an interactive interface capable of performing man-machine interaction is displayed on the second display screen. The interactive interface at least comprises an abnormal type selection area and an abnormal position selection area, wherein the abnormal type selection area is provided with a plurality of options for representing abnormal type information, and the abnormal position selection area is provided with a plurality of options for representing abnormal position information. The operator selects the considered abnormal type information option and the abnormal position information option and clicks the 'confirm' button, so that the point screen device can receive feedback information generated by the input operation, and further can judge whether the feedback information accords with the abnormal information simulated by the first blind test image.
In order to fully demonstrate the display performance of the display screen as much as possible, the dot screen device typically sends a plurality of standard images with different display effects to the display screen sequentially, and it is quite specific to use one or more of the plurality of standard images as the first reference image of the first blind test image generation basis. In particular to the present embodiment shown in fig. 1, this can be done (see fig. 3):
s301, randomly extracting N reference images from a plurality of reference images to be transmitted as a first reference image, where N is a natural number, and the value of N is determined according to the total number of the plurality of reference images and a preset first blind measurement rate, and the first blind measurement rate indicates a ratio of the total number of the first reference images to the total number of the plurality of reference images.
In an example a, the dot screen device is to send a total of 21 different reference images to the display screen under test to verify the display effect of the display screen under test on the 21 reference images, respectively. The manager may manually set the first blind measurement rate he wishes, for example, set the first blind measurement rate to 10%, which means that: two reference images (21×10% =2.1 is not an integer, rounded to 2) are randomly extracted from the 21 reference images as two first reference images, respectively. The aforementioned two first reference images are different images.
Further, in the foregoing example a, before step S301, the method further includes:
s300, a blind test starting mode is randomly determined according to a preset second blind test rate, wherein the second blind test rate indicates the probability of starting the blind test detection mode.
For example, in the foregoing example a, the administrator manually set the second blind test rate to 1% in advance for the point screen device, which means that: the probability of starting the blind test detection mode is 1%, that is, the spot-screen program runs 100 times per cycle (for detecting 100 display screens in sequence), and approximately 1 time is the blind test mode, namely, 20 standard images and two blind test images are sent, and the other 99 times are all the normal detection modes, namely, only 20 standard images are sent and no blind test image is sent.
It can be understood that by setting the second blind measurement rate in the dot screen device, and randomly determining whether to start the blind measurement detection mode currently according to the second blind measurement rate (the larger the second blind measurement rate is, the higher the probability of starting the blind measurement detection mode currently is, and the lower the probability is, if the second blind measurement rate is zero, the blind measurement detection mode will not be started currently), the method is more automatic, and communication with the MES is not needed to determine whether to start the blind measurement detection mode.
That is, in example a, the operations of S301 to S304 described below are performed on the premise that the screen pointing device just randomly determines that the blind test detection mode is currently turned on (obviously, the blind test module can be turned on currently, and the preset second blind test rate is not zero), and if the screen pointing device randomly determines that the blind test mode is not turned on currently according to the preset second blind test rate, and performs the screen pointing detection in the normal mode, the steps of S301 to S304 described below are not performed this time. Obviously, when the second blind detection rate is 1%, the blind detection mode is not turned on in most cases.
S302, copying each of the N reference images once to obtain N pairs of first reference images.
In the foregoing example a, the dot screen device copies two first reference images randomly extracted from 20 reference images, respectively, once, to obtain two pairs of first reference images, and the two first reference images in the same pair are identical.
S303, adding a first abnormal simulation graph to a random part of one of the N pairs of first reference images to obtain N first blind test images, and further obtaining an image queue containing the plurality of reference images and the N first blind test images.
For convenience of description, the two first reference images in example a will be referred to as a first pair of first reference images and a second pair of first reference images, respectively. And adding a first abnormal simulation pattern to the random part of one first reference image in the first pair of first reference images by the dot screen device to obtain one first blind test image, and adding a first abnormal simulation pattern to the random part of one first reference image in the second pair of first reference images by the dot screen device to obtain the other first blind test image. Thus, two different first blind test images are obtained together, and the positions and/or types of the first abnormal simulation patterns in the two first blind test images can be the same or different. Thereby, an image queue including the 21 reference images and the 2 first blind test images is obtained.
S304, sequentially sending each reference image and each first blind test image in the image queue to a display screen, and after each time of sending one first blind test image, acquiring feedback information of an operator for the first blind test image, sending a first reference image corresponding to the first blind test image; for each first reference image and one first blind test image corresponding to the first reference image, the first reference image and the first blind test image are sent to a display screen by the point screen device in a sequential adjacent mode without any other reference images.
In the foregoing example a, for convenience of description, the 21 reference images are respectively referred to as 1 st to 21 st reference images in preset transmission order, and assuming that the dot screen device randomly selects the 5 th and 12 th reference images among the 21 reference images as the first reference image, the dot screen device transmits the first blind test image corresponding to the 5 th reference image after transmitting the 4 th reference image to the display screen to be tested. Subsequently, the 5 th to 11 th reference images are sequentially transmitted. Subsequently, another first blind test image corresponding to the 12 th reference image is transmitted. Subsequently, 12 th to 21 st reference images are sequentially transmitted.
It is understood that the contents of the foregoing steps S101 to S103 specifically correspond to the contents of the foregoing step S304.
In addition, the embodiment of the application also provides a point screen device, which comprises: a memory, a processor connected to the memory, a program stored in the memory and executable by the processor; wherein the processor, when executing the program, implements the method described above.
In addition, the embodiment of the application also provides a computer readable storage medium, wherein a program is stored in the storage medium, and when the program is executed by a computer device, the method can be realized.
