Embodiment Construction

[0020] figure 1 According to an embodiment of the present invention, a schematic diagram of an image recognition device 100 is shown, wherein the image recognition device 100 is used to recognize a liquid crystal display module (for example: such as figure 2 Defects on the liquid crystal display module 200 shown). Defects include, for example: scratches, air bubbles, glue residue, oil stains or dust, etc.

[0021] The image recognition device 100 may include a processor 110 , a storage medium 120 , a transceiver 130 , an image capture device 140 and a first light emitting element 150 . In an embodiment, the image recognition device 100 may further include a second light emitting element 160 . However, the number of light emitting elements of the image recognition device 100 can be configured by the user according to requirements, and the present invention is not limited thereto.

[0022] The processor 110 is, for example, a central processing unit (central processing unit,...

Abstract

The invention provides an image identification device and an image identification method, which are used for identifying flaws on a liquid crystal display module, and the surface of the liquid crystal display module is covered with a protective film. The image recognition method comprises the following steps: providing at least one side light source to irradiate the liquid crystal display module; acquiring at least one blank screen image of the liquid crystal display module under at least one side light source in a non-display state, and acquiring a marked area from the at least one blank screen image when the at least one blank screen image has flaws; acquiring a plurality of images of the liquid crystal display module in the darkroom in a display state; and identifying at least one flaw on the liquid crystal display module according to the plurality of images and the marked area. The image recognition device and the image recognition method can quickly and accurately carry out image recognition.

Description

technical field [0001] The present invention relates to an electronic device and an identification method using the electronic device, and in particular to an image identification device and an image identification method for identifying defects on a liquid crystal display module. Background technique [0002] As people's demand for different types of display panels such as TVs, electronic signboards, notebook computers, mobile phones, or car displays increases, display panels are gradually developed to have various sizes, resolutions, and specifications. Among various display technologies, a liquid crystal display module (LCM) is the most mature and widely used display panel technology. The liquid crystal display module does not emit light through its liquid crystal display panel, but provides brightness by projecting light from the rear backlight module. The backlight module is mainly composed of an optical film, a light guide plate, a diffusion sheet, a reflection sheet,...
