Problems solved by technology

[0006] This manual detection mode often has the following problems: it is impossible to ensure that workers have observed each displayed picture with the naked eye
Since the picture switching button is at a fixed position on the screen, during the screen test operation, workers may not pay attention to the screen at all, but simply click the picture switching button repeatedly, so that various tests can be successfully completed, which will As a result, there are often unfavorable phenomena that are missed, which eventually leads to the flow of defective products out of the factory, reducing the qualified rate of ex-factory products

Embodiment 1

[0040] see figure 1 , an embodiment of the present invention provides a screen fool-proof detection method, including:

[0041] Step 101, selecting several test pictures to form a test picture set.

[0042] The selected test pictures are output to be displayed on the screen to be tested, and workers can determine various defects of the screen to be tested by visual observation.

[0043] Based on the different defect test items, test pictures that meet different requirements and different quantities can be selected according to needs.

[0044] Defect test items may include, but are not limited to: light leakage, dead pixels, chromatic aberration, etc.

[0045] In this embodiment, 12 test pictures are selected, which are respectively: Red, Blue, Green, Gray255, Gray127, xm_d1s Gray64, Gray0, Edgechecker, Cross2, Cross3, Flicker, Transition_gray; the meanings, selection requirements and The effect is described in the table below:

[0046]

[0047]Step 102, display each tes...

Embodiment 2

[0062] In the first embodiment, the display position of the picture switching button is adjusted from a fixed method to a random generation method to achieve a fool-proof effect, which can effectively prevent workers from missing any test picture due to various factors during the manual inspection process.

[0063] On the basis of the first embodiment, the second embodiment will further improve the anti-fooling effect: each time a new test picture is switched to be displayed, the screen will be automatically locked, and the lock screen will be locked for a preset duration, such as 2 seconds.

[0064] After the screen lock time is reached, the screen will be unlocked automatically, and the worker can switch the picture display by clicking the button.

[0065] Through the automatic lock screen operation and the setting of the lock screen duration, on the one hand, it can remind the workers to observe the current test picture with the naked eye, avoiding the workers to directly cl...

Embodiment 3

[0067] Embodiment 3 provides a screen fool-proof detection device, including:

[0068] A test picture selection unit is used to select a plurality of test pictures to form a test picture set;

[0069] The display switching unit is used to sequentially display each test picture in the test picture set on the screen under test for human observation; at the same time, when switching to display a new test picture each time, update the picture switching button on the screen under test display position, and perform picture display switching after the switching command is collected through the picture switching button;

[0070] The lock screen control unit is used to automatically lock the screen after switching to display a new test picture each time and before collecting the switching instruction through the picture switching button, and the lock screen duration is a preset value.

[0071] In addition, a button coordinate generation unit is also included, which is used to, when th...

Abstract

The invention relates to the technical field of screen detection, and discloses a screen fool-proof detection method and device and a storage medium. The screen fool-proof detection method comprises the following steps: selecting a plurality of test pictures to form a test picture set; sequentially displaying each test picture on a tested screen in a single mode; and updating the display positionof a picture switching button when a new test picture is switched and displayed every time, and executing picture display switching after a switching instruction is acquired through the picture switching button. In the embodiment of the invention, when the test pictures are sequentially switched and displayed, the display positions of the picture switching buttons before and after switching are different, so that a worker cannot realize picture display switching at a previous button position through clicking operation, and the switching is realized by looking up a new button position by observing the tested screen and carrying out clicking operation. Therefore, workers can execute the next operation only after visual observation, the fool-proof effect is realized, and the probability of missed detection can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of screen defect detection, in particular to a screen fool-proof detection method, device and storage medium. Background technique [0002] LCD screens are more and more widely used in mobile phones, televisions and computers, and are closely related to people's lives. The quality of the LCD screen, specifically the quality of the pixels, determines people's experience. In order to improve the qualification rate of the LCD screens that leave the factory, it is necessary to carry out various defect inspections on the LCD screens that have been produced, such as light leakage, dead pixels, and chromatic aberration. [0003] The light leakage of the LCD screen refers to the phenomenon that in a complete display product, there is a relatively obvious phenomenon of light overflow at the junction of the frame frame and the edge of the screen display. It is not allowed to be produced, and it may also be caused by...
