Abstract
The invention is applied in the field of a liquid crystal displayer and provides a liquid crystal panel manufacturing method and a liquid crystal panel manufactured by the method. The method comprises the following steps of preparing a first glass substrate and a second glass substrate; taking a sealing adhesive as a screen printing material, and performing screen printing on the first glass substrate to form a plurality of prefabricated sealant frames and a plurality of bumps, wherein the bumps are positioned on the outer side of the side frame of each prefabricated sealant frame, the bumps and the corresponding side frames are arranged at intervals, and the bumps are positioned between the corresponding side frames and cutting lines corresponding to the side frames; filling a liquid crystal material into the prefabricated sealant frames; covering the second glass substrate on the first glass substrate and aligning the second glass substrate to the first glass substrate; curing each prefabricated sealant frame and each bump at high temperature to form a sealed sealant frame, and sticking the first glass substrate and the second glass substrate; cutting the first glass substrate and the second glass substrate along cutting lines to obtain the liquid crystal panel. Due to the fact that the bumps and the prefabricated sealant frames are arranged at intervals, formed sawteeth are prevented from being cut during cutting, and the aim of preventing a needle-loading adhesive-dispensing rainbow is fulfilled.
Description
technical field [0001] The invention belongs to the field of liquid crystal displays, and in particular relates to a method for manufacturing a liquid crystal panel and a liquid crystal panel manufactured by using the method. Background technique [0002] The liquid crystal panel is based on the liquid crystal material. Liquid crystals are placed between two parallel glass substrates. There are many small vertical and horizontal wires in the middle of the two glass substrates. The direction of the rod-shaped crystal molecules is controlled by electrifying or not. The light is refracted to create the picture. Therefore, when making a liquid crystal panel, it is necessary to make a sealant frame on the glass substrate, support the two glass substrates, and form a sealed cavity with the two glass substrates, and then fill the sealed cavity with liquid crystal material to form an LCD (liquid crystal panel). Pins (that is, PIN pins) also need to be installed on the liquid crysta...
