Patent ID: 10718978

Abstract:
Disclosed is an apparatus for improving optical alignment of panels manufactured on a same mother substrate. The technical defect in the prior art which affects product quality can be eliminated. The apparatus for improving optical alignment of panels manufactured on a same mother substrate includes a mother substrate (1), N columns of chips in a first group (2), N columns of chips in a second group (3), and a photomask (4). The N columns of chips in the first group (2) and the N columns of chips in the second group (3) are arranged in an alternate manner and are arranged on the mother substrate (1). An area of the chips in the second group (3) is larger than an area of the chips in the first group (2). The photomask (4) covers the N columns of chips in the first group (2) and the N columns of chips in the second group (3) so that ultraviolet irradiates the N columns of chips in the first group (2) and the N columns of chips in the second group (3) after passing through the photomask (4). N is a positive integer. The apparatus can be used in manufacturing of TFT-LCD.
