Title:
ALIGNING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/118196
Kind Code:
A1
Abstract:
Disclosed is an aligning device, which is used to align a first substrate (3) and a second substrate (4) of a display panel. The aligning device comprises: a first platform (1) and a second platform (2) arranged oppositely; a light-emitting unit (5), arranged on the surface of the first platform (1) facing the second platform (2) and used for emitting light toward the second platform (2); a photosensitive unit (6), arranged on the surface of the second platform (2) facing the first platform (1) and used for sensing the light intensity of the light emitted by the light-emitting unit (5); and a control unit (CU), used for adjusting the position of at least one of the first platform (1) and the second platform (2) until the sensed light intensity is less than a pre-set light intensity when the sensed light intensity is greater than or equal to the pre-set light intensity. By means of the mutual cooperation between the light-emitting unit (5) and the photosensitive unit (6) independent of the two substrates, the condition of aligning the two substrates can be determined accurately according to a light intensity received by the photosensitive unit (6), and moreover, the positions of the two platforms are adjusted, so that the two substrates are aligned accurately.
