Problems solved by technology

However, in order to make the detection results very accurate and avoid the occurrence of some defects not being detected, it is necessary to carry out quite a few image processing procedures
Due to the large number of images that need to be processed, the automatic optical inspection method takes a long time to inspect each LCD panel, which will naturally have a negative impact on the overall production efficiency and production capacity.

Embodiment Construction

[0025] The first specific embodiment according to the present invention is an optical detection device. In this embodiment, the optical detection device is used to detect the defect distribution of the display panel, so as to ensure that the display panel shipped from the factory can have excellent and reliable quality without defects such as bright spots. The display panel may be a liquid crystal display panel or other display devices, but is not limited thereto. Please refer to figure 1 and figure 2 , figure 1 Shown is a schematic diagram of the optical detection device for defect detection of the display panel; figure 2 Shown is a functional block diagram of the optical detection device.

[0026] Such as figure 2 As shown, the optical detection device 1 includes an image capture module 10 , an image processing module 12 and a storage module 14 . The image processing module 12 is coupled to the image capture module 10 and the storage module 14 is coupled to the imag...

Abstract

The invention provides an optical detecting device. The optical detecting device comprises an image acquisition module and an image processing module. The image acquisition module is used for acquiring a plurality of images displayed on a display panel at different time. The image processing module generates a superimposed image according to the acquired images and further generates defect distribution information corresponding to the display panel according to the superimposed image.

Description

technical field [0001] The present invention relates to an optical detection device and an optical monitoring method, and in particular, relates to an optical detection device and an optical detection method for detecting defect distribution of a display panel. Background technique [0002] In recent years, with the continuous development of image display-related technologies, various new types of display devices different from traditional displays have appeared on the market, such as liquid crystal displays and plasma displays. Among them, liquid crystal display or liquid crystal TV and other products using liquid crystal display technology have the highest penetration rate. [0003] Before the liquid crystal display produced by the factory is shipped, it needs to be inspected by inspectors. Generally speaking, at present, most manufacturers have improved the traditional manual inspection method to automatic optical inspection (Automatic Optical Inspection, AOI) method for...
