Abstract

PROBLEM TO BE SOLVED: To provide an inspection device capable of inspecting a display panel continuously and rapidly.SOLUTION: A display panel inspection device includes: a panel installation jig 12 that has a panel installation portion on which a panel is installed; a backlight 15 that is provided to the panel installation jig for radiating light onto a lower portion of the panel; a photographing device 18 for photographing the panel installed on the panel installation jig; and a photographing device movement unit 34 that moves the photographing device. The photographing device includes: an inspection camera 20 that is disposed so that a lens portion faces the panel; an inspection camera rotation device 23 that rotates the inspection camera so that a photographing angle of the inspection camera with respect to the panel is changed; a frame 22 that supports the inspection camera rotation device; an illumination device 21 for radiating light onto an upper portion of the panel which the inspection camera photographs; and an illumination device movement unit 25 that is coupled to the frame so as to support the illumination device and moves the illumination device so that an angle of light irradiation of the illumination device is changed.

Description

technical field [0001] The present invention relates to an inspection device of a display panel, and more specifically, an inspection device capable of rapidly and accurately inspecting various display panels. Background technique [0002] Recently, with the launch of various digital devices such as smartphones, digital TVs, tablet PCs, notebooks, PMPs, and navigators, the demand for display panels used in flat panel display devices and touch screens has gradually increased. [0003] The flat panel display device includes a liquid crystal display (LCD), a plasma display (PDP), an organic light emitting display (OLED), and the like. Liquid crystal displays are widely used as display devices for various digital devices due to their features such as light weight, thin profile, low power drive, full color, and high resolution. [0004] A liquid crystal display is manufactured by pasting a polarizing plate and a backlight unit on a liquid crystal display panel that controls ligh...
