Embodiment 1

[0031] like figure 1 and figure 2 As shown, the appearance visual detection method and device for AMOLED screens of the present invention ensure the speed and accuracy of appearance detection through the combination of high and low angles of light sources and image analysis and processing modules, and are mainly used for AOI detection of the appearance of AMOLED screens .

[0032] The specific process of the visual inspection method includes the following steps:

[0033] S1. Select the light-colored carrier 4, and place the AMOLED screen 3 to be inspected on the light-colored carrier 4;

[0034] S2. More than two strobe light sources are respectively fixed above the sides of the AMOLED screen body 3 to be inspected, and irradiate on the AMOLED screen body 3 to be inspected at a high angle and a low angle respectively;

[0035] S3. Install a line-scan camera 5 in the reflected light direction of the stroboscopic light source, and the line-scan camera 5 accepts high-angle an...

Embodiment 2

[0050] Such as figure 2 As shown, a visual inspection device for the appearance of an AMOLED screen of the present invention includes a lighting module that emits and reflects light sources, a line-scan imaging module that collects images, and an image analysis and processing module that analyzes and processes images and obtains data processing results. , the lighting module includes a first strobe light source 21, a second strobe light source 22, a light-colored carrier 4 for placing the AMOLED screen body 3 to be checked, the line-scan imaging module includes a line-scan camera 5, the first strobe light source 21, The second stroboscopic light source 22 is respectively fixed on the top of the AMOLED screen body 3 to be checked at a high angle and a low angle. The array camera 5 and the light-colored stage 4 are respectively connected and transmit data to the image analysis and processing module 1 .

[0051] The image analysis and processing module 1 includes a PC terminal ...

Abstract

The invention relates to an AMOLED screen body appearance visual detection method and device. The method comprises the following steps that: S1, a light-color carrying table is selected, and a to-be-detected AMOLED screen body is placed on the light-color carrying table; S2, stroboscopic light sources are fixed to the lateral upper portions of the to-be-detected AMOLED screen body respectively andirradiate the to-be-detected AMOLED screen body at a high angle and a low angle respectively; S3, a line-scan digital camera is installed in the reflected light direction of the stroboscopic light sources, wherein the line-scan digital camera receives high-angle and low-angle reflected light imaging; S4, the linear array camera collects images; S5, the images are analyzed and processed, and a data processing result is obtained; and S6, whether a detection requirement is met or not is judged according to the data processing result, and if not, the angles of the stroboscopic light sources are slightly adjusted, and a lighting scheme is optimized until a detection algorithm requirement is met. According to the invention, the accuracy of appearance detection is improved, a plurality of photoscan be processed in parallel, and the detection speed is improved.

Description

technical field [0001] The invention relates to the field of appearance inspection, in particular to a visual inspection method and device for the appearance of an AMOLED screen body. Background technique [0002] For panel display, especially the AMOLED flat panel display manufacturing industry, due to the many production processes and complicated manufacturing links, it is inevitable to cause certain defects on the appearance of the product during the production process, such as scratches, bumps, dirt, damage, etc. , and the appearance defects of the screen body will not only affect its appearance, but may also affect the performance of the screen body. Provide a basis for improvement. At present, the vast majority of appearance inspection is through manual inspection. This method is easy to cause visual fatigue and misjudgment, and the inspection speed is slow, which affects production efficiency. Therefore, appearance inspection equipment based on machine vision has beg...
