The main function of the shading adhesive tape of the liquid crystal display module is to prevent backlight from penetrating through the liquid crystal panel, so that light leakage phenomenon is generated in a specific area. The shading adhesive tape is generally arranged around the frame of an electronic liquid crystal display screen of a computer, a mobile phone, a vehicle-mounted electronic liquid crystal display screen and the like.

In view of the foregoing, it is desirable to provide a method for detecting riding on a tape, so as to improve the detection efficiency and reduce the detection cost while effectively detecting the bad condition of riding on a slight tape.
Specific embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating an exemplary method for detecting riding on a tape according to some embodiments of the present application, where riding on the tape according to the embodiments of the present application means that a light shielding tape is not completely attached to an adhesive tape attaching area, so that a part of the light shielding tape protrudes and is attached to a side wall of a screen of a liquid crystal display to be tested, and such a poor attachment phenomenon of the light shielding tape may affect a light shielding effect of the liquid crystal display. Referring to fig. 1, the method for detecting riding on a rubber belt according to the present application may include:
In step S101, the liquid crystal display to be tested is conveyed to the testing platform through the liquid crystal display carrying device. In the embodiment of the application, the detection platform can be provided with at least one high-angle short-wave light source and at least one low-angle long-wave light source. The light shielding tape is arranged on the surface of the liquid crystal display screen, and is used for irradiating the main body part of the light shielding tape attached to the surface direction in the attaching area. In addition, the long-wave light of the low-angle long-wave light source irradiates the side edge of the attaching region of the masking tape, and can be used for irradiating the side edge of the attaching region at a diagonal position opposite to the setting position of the low-angle long-wave light source. It can be understood that if the shading tape has a slight bad riding phenomenon in the liquid crystal display to be tested, that is, the shading tape is only ridden and attached to the side wall of the screen of the liquid crystal display to be tested but not attached to the surface of the screen of the liquid crystal display to be tested, then the bad attaching part of the shading tape is ridden slightly beyond the side wall of the screen of the liquid crystal display to be tested, so that the light is illuminated by the long wave light of the low-angle long wave light source, and conversely, the light of the short wave light of the high-angle short wave light source cannot illuminate the bad attaching part of the shading tape.
In the embodiment of the present application, a certain included angle may be formed between the short-wave light of the high-angle short-wave light source and the long-wave light of the low-angle long-wave light source, and the included angle may be set to be greater than or equal to 45 ° and less than 90 °, preferably may be set to be 60 °, and in practical application, the included angle needs to be set according to the practical application situation.
In step S102, an attached area of the masking tape is imaged by a color camera to obtain an image to be detected. In the embodiment of the application, the number of the color cameras can be set to be consistent with that of the high-angle short-wave light sources or the low-angle long-wave light sources, and the high-angle short-wave light sources, the low-angle long-wave light sources and the color cameras can be correspondingly matched. Further, the imaging optical axis of the color camera is perpendicular to the attaching area of the shading adhesive tape, and the light reflected by the short-wave light of the high-angle short-wave light source irradiating the main body part of the shading adhesive tape and the light reflected by the long-wave light of the low-angle long-wave light source irradiating the attaching defective part of the shading adhesive tape can enter the matched color camera for imaging.
In step S103, the image to be detected is preprocessed, and a preprocessed image is obtained. In the embodiment of the present application, the foregoing preprocessing may be processing for a color space of an image to be detected, so as to be capable of conveniently performing subsequent processing on the color of the image to be detected.
In step S104, a short-wave light imaging region and a long-wave light imaging region are determined based on the preprocessed image. In the embodiment of the application, the short wave light imaging area and the long wave light imaging area can be distinguished by preprocessing the colors of the images, so that the short wave light imaging area and the long wave light imaging area are determined.
In step S105, it is determined whether the liquid crystal display to be tested has bad riding on the adhesive tape based on the short wave light imaging area and the long wave light imaging area. It can be understood that if the liquid crystal display to be tested does not have bad riding on the adhesive tape, the long-wave light imaging area should not exist. If the long-wave light imaging area does not exist, it can be determined that the liquid crystal display screen to be tested does not have bad riding phenomenon of the rubber belt.
According to the embodiment of the application, the liquid crystal display to be detected is conveyed to the detection platform through the liquid crystal display carrying device, wherein the detection platform is provided with the high-angle short-wave light source and the low-angle long-wave light source, the short-wave light of the high-angle short-wave light source is perpendicular to the shading adhesive tape of the liquid crystal display to be detected, and the long-wave light of the low-angle long-wave light source irradiates the side edge of the attaching area of the shading adhesive tape. And imaging the attached area of the shading adhesive tape through a color camera to obtain an image to be detected, wherein the imaging optical axis of the color camera is perpendicular to the attached area of the shading adhesive tape. Therefore, the main body part of the shading adhesive tape positioned in the attaching area can be illuminated and imaged through the high-angle short-wave light source and the color camera, and the poor attaching part of the shading adhesive tape which is positioned outside the attaching area and slightly ridden on the screen side wall of the liquid crystal display to be tested can be illuminated and imaged through the low-angle long-wave light source and the color camera. Further, the application can preprocess the image to be detected to obtain a preprocessed image. And then confirm short wave light imaging area and long wave light imaging area based on the preliminary treatment image, and then confirm whether the liquid crystal display that awaits measuring exists the area and ride bad phenomenon on the rubber belt based on short wave light imaging area and long wave light imaging area. Thus, the bad riding phenomenon on the shading adhesive tape in the liquid crystal display to be tested can be detected. In general, the embodiment of the application can effectively detect the bad condition of riding on the slight adhesive tape, and simultaneously improve the detection efficiency and reduce the detection cost.
In some embodiments, the preprocessing for the image to be detected may be further designed. The preprocessing process will be described in detail with reference to fig. 2. Fig. 2 is a flowchart illustrating an exemplary method for detecting riding on a rubber belt according to other embodiments of the present application, referring to fig. 2, the method for detecting riding on a rubber belt according to the embodiment of the present application may include:
in step S201, an image to be detected is read, and color space conversion is performed on the image to be detected, so as to obtain a preprocessed image. In the embodiment of the application, in the process of performing color space conversion on the image to be detected, the RGB color space of the image to be detected can be converted into the HSV color space, or the RGB color space of the image to be detected can be converted into the Lab color space.
The above-mentioned HSV color space is an HSV color model, which refers to a visible light subset in a three-dimensional color space of H (hue), S (saturation), and V (lightness), and includes all colors of a certain color gamut. HSV color space handles color changes more easily than RGB color space, particularly in the fields of computer graphics and image processing.
The Lab color space is a Lab color model, and the Lab color model consists of three elements of brightness (L) and related colors, namely a and b. L represents brightness (Luminosity), a represents a range from magenta to green, and b represents a range from yellow to blue.
In step S202, a short-wave light color division threshold range and a long-wave light color division threshold range are set based on the preprocessed image. In the embodiment of the application, the short-wave light color segmentation threshold range can be determined according to the gray value coverage of the short-wave light color, and the long-wave light color segmentation threshold range can also be determined according to the gray value coverage of the long-wave light color. It will be appreciated that in practical applications, the manner of setting the short-wavelength light color division threshold range and the long-wavelength light color division threshold range is various, and the short-wavelength light color division threshold range and the long-wavelength light color division threshold range need to be set according to practical application conditions, and the present application is not limited in this respect.
In some embodiments, the respective short-wave light imaging region and long-wave light imaging region may be determined from a range of color segmentation threshold values for the long-wave light and the short-wave light. The process of confirming whether there is bad riding on the adhesive tape will be described in detail with reference to fig. 3. Fig. 3 is a flowchart illustrating an exemplary method for detecting riding on a rubber belt according to still other embodiments of the present application, and referring to fig. 3, the method for detecting riding on a rubber belt according to the embodiment of the present application may include:
In step S301, a short-wave light imaging region is determined based on the short-wave light color division threshold range. In the embodiment of the application, if the pixel gray value in the preprocessed image is within the range of the shortwave light color segmentation threshold, the pixel gray value is updated to the gray value corresponding to black, and the gray value corresponding to black is 0, so that the area formed by the black pixels forms a shortwave light imaging area.
In step S302, a long-wave light imaging region is determined based on the long-wave light color division threshold range. In the embodiment of the application, if the pixel gray value in the preprocessed image is within the range of the long-wave light color segmentation threshold, the pixel gray value is updated to the gray value corresponding to white, and the gray value corresponding to white is 255, so that a long-wave light imaging area is formed by the area formed by the white pixels.
It should be understood that the execution timing of the step S301 and the step S302 is not limited, and may be executed simultaneously or sequentially, and in practical application, the present application is not limited in this respect.
In step S303, it is determined whether the liquid crystal display to be tested has bad riding on the adhesive tape based on the short wave light imaging area and the long wave light imaging area. In the embodiment of the application, the situation that the long wave light rays of the low-angle long wave light source are wrongly irradiated to other positions, so that the positions are wrongly regarded as long wave light imaging areas can occur. Therefore, it is necessary to determine the detection contour area corresponding to the liquid crystal display screen to be detected based on the short-wave light imaging area first, and only the long-wave light imaging area within the detection contour area can be used as an effective long-wave light imaging area formed by irradiating the defective attachment portion of the light-shielding adhesive tape. Therefore, in the embodiment of the application, if the long-wave light imaging area is located in the detection contour area and the area size of the long-wave light imaging area is larger than the preset specification size, the phenomenon of bad riding on the rubber belt of the liquid crystal display screen to be detected is determined. And on the contrary, the rest conditions determine that the liquid crystal display screen to be tested has no bad riding phenomenon on the rubber belt.
Corresponding to the embodiment of the application function implementation method, the application also provides electronic equipment for executing the method for detecting the riding on the rubber belt and corresponding embodiment.
Fig. 4 shows a block diagram of a hardware configuration of an electronic device 400 in which the tape ride detection method of an embodiment of the present application may be implemented. As shown in fig. 4, electronic device 400 may include a processor 410 and a memory 420. In the electronic apparatus 400 of fig. 4, only constituent elements related to the present embodiment are shown.
