Abstract

The invention discloses an objective lens adjusting assembly and an OLED display device defect inspection device thereof. The objective lens adjusting assembly comprises a mounting plate, a sliding plate and a plurality of objective lenses; the mounting plate is horizontally arranged; a first through hole vertically penetrating through the upper end is formed in the middle of the upper end; the sliding plate is horizontally installed at the lower end of the installation plate in a sliding mode in the left-right direction; a plurality of second through holes in one-to-one correspondence with the objective lenses are formed in the sliding plate in the left-right direction at intervals; the multiple objective lenses are arranged under the sliding plate; the upper end of each objective lens isembedded in the corresponding second through hole; and the sliding plate slides in the left-right direction under the action of external force till any one objective lens is aligned with the first through hole. Therefore, different objective lenses can be aligned with the first through hole by sliding the sliding plate in the left-right direction, and the objective lenses with different magnification times can be flexibly used as required.

Description

technical field [0001] The invention belongs to the field of testing equipment for OLED display devices, and in particular relates to an objective lens adjustment assembly and a defect inspection device for OLED display devices. Background technique [0002] Due to the development of multimedia display industries such as mobile phones and TVs, the semiconductor display panel market has become huge, and the demand for semiconductor display panels has increased year by year. Therefore, the demand for semiconductor display panel processing, testing and repair technologies has also greatly increased. For the defect detection of OLED displays, especially the detection of bright and dark spots on the screen, there is no equipment that is fast, accurate, adaptable, and easy to operate. Contents of the invention [0003] In order to solve the above technical problems, one object of the present invention is to provide an objective lens adjustment assembly with simple structure and ...
