Detailed Description
The invention is described in detail below with reference to fig. 1 and the specific embodiments.
The invention relates to a method for detecting the subareas of a display screen, which comprises the following steps:
firstly, setting a plurality of detection pictures according to the size of a display screen;
then, dividing each detection picture in the plurality of detection pictures into a plurality of detection areas according to the same division rule, wherein the number of the detection pictures is consistent with that of the detection side areas on each detection picture, one detection area in the plurality of detection areas of each detection picture is an active area, and the rest detection areas are inactive areas; according to the requirements of detection items, the active areas are generally white, pure red, green, blue or colored, the non-active areas are always set to be black, when production line workers detect the active areas, other non-active areas display black, no residual light enters human eyes, and the probability of misjudgment is reduced. Specifically, if the display screen size is smaller, that is: the detection of the whole display screen can be locked in the visual focusing range of human eyes (generally, the focusing range is 30cm away from the human eyes to the display screen), a detection picture can be set, the whole picture of the detection picture is a moving area, and the display screen is driven to display the detection picture, so that the detection of the display screen is realized. For the situation that the size of a display screen is large and the whole screen cannot be locked within a human eye focusing range (generally, the focusing range when the human eye is 30cm away from the display screen), a plurality of detection pictures are set, each detection picture is divided into a plurality of detection areas, each detection picture is provided with an active area, the area of each active area is set to be locked within the focusing range when the human eye is 30cm away from the display screen, for example, 1 detection picture can be set on the display screen below 2.4 inches, the number of the active areas is also 1, and the whole detection picture is an active area; 2 detection pictures are arranged on a 2.4-4.9 inch display screen, and the active area of the 2 detection pictures covers the whole display area of the display screen; setting 4 detection pictures on a display screen of 5-7.9 inches, wherein 4 active areas of the 4 detection pictures cover the whole display area of the display screen; 6 detection pictures are arranged on the display screen of 8-10 inches, and 6 active areas of the 6 detection pictures cover the whole display area of the display screen.
And finally, driving the display screen to sequentially display a plurality of detection pictures at a set time interval, wherein all moving areas of the plurality of detection pictures just cover the whole display screen after the detection is finished. After the data statistics analysis is carried out on the usual detection time of production line staff, the display time of each detection picture is set to be 0.5-3 seconds, most preferably 1.5 seconds, the detection task can be fully completed, and the long detection time caused by overlong display time can be avoided. When the display screen displays a plurality of detection pictures in full screen in sequence, the moving area of the last displayed detection picture and the moving area of the next displayed detection picture are arranged next to each other. Visual jumping of human eyes is reduced, and detection work of production line staff is facilitated.
The following description will be made in detail taking the detection of a 5-inch display screen as an example.
First, 4 test pictures A, B, C, D are set, and the size and resolution of the 4 pictures are the same. Equally dividing each detection picture into 4 detection areas, wherein one detection area is set as an active area and the other detection areas are inactive areas, and it is worth mentioning that the active area in each detection picture is different from the active areas of the other detection pictures, so that the whole display area can be completely detected during detection. As shown in fig. 1, A, B, C, D is 4 inspection pictures, where a1, B2, C3, and D4 are active areas, and the other areas a2, A3, a4, B1, B3, B4, C1, C2, C4, D1, D2, and D3 are all inactive areas, and the inactive areas are always black in the inspection picture. When the detection picture is displayed on the display screen, the 4 activity areas are all located in different areas of the display screen, and the 4 activity areas just cover the whole display screen, so that the sub-area detection of the display screen is realized. The condition that the omission of the boundary division of human eyes causes missed detection or the overlapping of the boundary division causes repeated labor in the existing operation mode is avoided. The colors of the active areas a1, B2, C3, D4 are set according to the items to be detected, and the colors of the 4 active areas are all set to white, as in the black dot test. Utilize MCU drive display screen full screen display in proper order above 4 to detect the picture, the display screen is when showing 4 in proper order and detect the picture, go on according to showing A1 in proper order, B2, C3, D4 or D4, C3, B2, the order of A1, people's eye is detecting time-measuring like this, the vision realizes the detection to the display screen active area clockwise or anticlockwise in proper order, there is not the vision jump, the convenience of detecting has been improved. Similarly, if the number of the detected pictures is more than 4, the operation convenience of the production line staff is more obvious by sequentially displaying the adjacent activity areas.
In addition, when a plurality of display items are to be detected, for example, bright lines or bright points are required to be detected in addition to black point detection, a plurality of groups of detection pictures can be set, the moving area of each group of detection pictures is respectively set to be red, green, blue or colored, and the like, the display screen is driven to sequentially display the plurality of groups of detection pictures, and the detection of the plurality of display items is realized.
In the embodiment, 4 detection pictures are set, the number of the detection pictures can be set according to the focusing range when the area of the moving region of each detection picture is smaller than 30cm away from the display screen by human eyes when each detection picture is displayed on the display screen, and the method is not limited to specific number, and the regional detection of the display screens with different sizes can be realized by utilizing the method.
In summary, the invention realizes the detection of the divided regions of the display screen by setting the plurality of detection pictures, dividing each detection picture in the plurality of detection pictures into the plurality of detection regions according to the same division rule, setting one detection region in each detection picture as an active region, driving the display screen to sequentially display the plurality of detection pictures in a full screen mode, and after the detection is finished, covering all the active regions of the plurality of detection pictures just over the whole display region of the display screen. The method for detecting the display screen in the divided areas is simple, but is greatly convenient for production line workers to detect the display screen, particularly the large-size display screen. The detection picture is directly utilized for partitioning, and human eyes are not needed for carrying out perception partitioning on the display screen, so that poor detection omission and repeated labor caused by omission or overlapping of the perception partitions are avoided, light rays in an inactive area enter the human eyes in a dark mode, misjudgment caused by light ray interference in the detection process is avoided, the production efficiency and the yield are improved, and the device is worthy of being widely popularized and used.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
