METHOD FOR DETERMINING SUBSTRATE, AND MANUFACTURING METHOD FOR FLEXIBLE DISPLAY USING THE SAME

摘要

An apparatus for determining a substrate is provided, including a light emitting unit, a light receiving unit, a memory unit, and a control unit. The light emit light is configured to emit light onto one surface of the substrate. The light receiving unit is configured to receive light reflected from the one surface of the substrate, and to detect optical information. The memory unit is configured to store the optical information of the received light and a reference value. The control unit is configured to determine whether the one surface of the substrate is a first surface or a second surface of the substrate by comparing the optical information and the reference value.

1. A method for determining a substrate, comprising:
preparing a substrate including a first surface and a second surface having different optical properties; detecting optical information on one of the first surface or the second surface of the substrate; and determining whether the one of the first surface or the second surface of the substrate is the first surface or the second surface of the substrate by comparing the optical information and a stored reference value.
