Description

Substrate identification jig and substrate identification method

The invention relates to an identification fixture and an identification method, and in particular to a method for identifying a substrate identification fixture and a substrate.

With the advancement of flat display technology and the advantages of flat display devices such as light weight, small size, and power saving, flat display devices have become more and more popular. Common flat display devices include liquid crystal display devices, plasma display panels (PDPs), organic light emitting diode displays (OLED Display), and electrophoretic display devices (EPD).

The substrate identification jig used in this embodiment is the substrate identification jig 100 shown in FIG. 2. In addition, the substrate identification jig 100 is used to identify a specific type of substrate. In the embodiment, the substrate identification jig 100 is used to determine whether the substrate 70 to be identified is the first type of substrate.

Next, the identification gap 72 of the substrate 70 is inspected by the identification portion 130 of the substrate identification jig 100. In more detail, the substrate 70 has a long side 74 and a short side 76, and an identification notch 72 connecting the long side 74 and the short side 76, and the identification gap of the substrate 70 is checked by the identification portion 130 of the substrate identification jig 100. The first step of the substrate identification fixture 100 is located next to the long side 74 of the substrate 70, and the second arm 120 of the substrate identification fixture 100 is positioned beside the short side 76 of the substrate 70.
