And a second transfer unit for linearly moving the position of the inspection stage (110).
Description
The present invention relates to a curved display panel inspection apparatus capable of performing an optical system inspection on a curved display panel.
In general, an LCD or an LED, which is one of the flat panel display panels, has better visibility than a cathode ray tube (CRT) and has a smaller average power consumption than a CRT having the same screen size, As a next-generation display device of a mobile phone, a computer monitor, and a television.
The LCD or LED is manufactured through various manufacturing processes. When starting or finishing each manufacturing process, an inspection process for inspecting a defect that may occur in a preceding manufacturing process or a corresponding manufacturing process is essentially required.
Such an inspection process is performed through various methods, among which there is an inspection method using an optical system.
In general, an inspection method using an optical system is mainly performed when a circuit and an image inspection of a display panel are performed. As shown in FIG. 1, in a conventional display panel inspection apparatus, a display panel P1 A
However, since the conventional display panel inspection apparatus configured as described above is optimized for inspection of the display panel P1 having a flat surface, it is difficult to perform a normal inspection in the case of the recently-developed curved display panel.
2, in order for the normal inspection to be performed, the
It is an object of the present invention to provide a curved display panel inspection apparatus capable of performing a quick and accurate optical system inspection on a curved display panel.
In order to achieve the above object, a curved display panel inspection apparatus of the present invention comprises: a curved surface plate on which a curved display panel to be inspected is placed; an inspection stage having a rotation unit for rotating the curved surface plate about a horizontal rotation axis; A first transfer unit for linearly moving the position of the camera in a vertical direction, a second transfer unit for moving the position of the inspection stage in a straight line And a second transfer unit for transferring the first transfer unit.
Further, the second transfer unit may be operated to linearly move the inspection stage in the horizontal direction and the inspection progress direction.
Also, the first transfer unit may be operated to linearly move the camera in the horizontal direction, and the second transfer unit may be operated to move the inspection stage in the inspection progress direction.
According to another aspect of the present invention, there is provided an apparatus for inspecting a curved display panel including a curved surface plate on which a curved display panel is mounted, the curved surface plate being rotatable in a normal and reverse direction through a rotation unit, It is possible to precisely perform the inspection of the optical system.
