Problems solved by technology

[0012] However, as mentioned above, the conventional inspection device has a structure that only touches one side of the display panel, so it is not convenient to inspect the above-mentioned display panel that has signal transmission plates on both sides and needs to contact both sides, and it is impossible to apply signals to both sides. , so it is difficult to check
[0013] In addition, assuming that there are contactors on both sides of the display panel for inspection, when the signal transmission board on one side of the display panel is aligned and contacted with the contactor, the position of the signal transmission board on the other side is fixed, Therefore, in order to align with other contactors, it is difficult to parallelize and rotate the signal transmission board on the other side, so there is a problem that it is difficult to check

Embodiment Construction

[0078] Hereinafter, the present invention will be described with reference to the drawings. However, the present invention can be embodied in many different forms and, therefore, is not limited to the embodiments described herein. In addition, in order to accurately describe the present invention in the drawings, parts irrelevant to the description are omitted, and similar reference numerals are assigned to similar parts throughout the specification.

[0079] Throughout the specification, when it is indicated that one part is "connected (coupled, contacted, combined)" with another part, this includes the case of "direct connection" and the case of "indirect connection" with other parts in between. Also, when it is indicated that a part "includes" another structural element, it does not mean excluding other structural elements, but may include other structural elements, as long as there is no particular statement to the contrary.

[0080] The terms used in the present inventio...

Abstract

One embodiment of the present invention provides a two-side alignment and inspection device for a display panel having a first signal transmission plate on one side and a second signal transmission plate on the other side in order to transmit an electrical signal. The two-side alignment and inspection device includes: a base on which the display panel is placed so as to inspect the display panel;a first contact unit that positions the first signal transmission plate on the base and applies an electric signal for inspection; and a second contact unit that moves in the X-axis direction, the Y-axis direction, and a rotational movement using the Z-axis as a rotational axis on the base, aligns with and contacts the second signal transmission plate, and applies an electric signal for inspection.

Description

technical field [0001] The present invention relates to a device for aligning and inspecting both sides of a display panel, and more specifically relates to a device for aligning and inspecting both sides of a display panel that enables the contact unit to move side by side and rotate to align and inspect the display panel. Background technique [0002] Display panels are widely used in televisions (TVs), monitors, mobile communication terminals, and the like. [0003] As a representative display panel, a liquid crystal display (LCD, Liquid Crystal Display) panel is used, but recently, an active mode organic light emitting diode panel (AMOLED panel, Active Mode Organic Light Emitting Diode Panel) is increasingly used. [0004] In general, an active organic light-emitting diode panel is a display that can display a desired image by individually supplying data signals based on image information to multiple pixels arranged in an active matrix (Active Matrix) form to control mul...
