Abstract

The invention discloses a liquid crystal dripping nozzle, a liquid crystal dripping device and a liquid crystal dripping method. The liquid crystal dripping nozzle comprises a main dropping nozzle and a plurality of auxiliary dripping nozzles, and the auxiliary dripping nozzles for liquid crystal dripping in marginal areas are arranged around the main dripping nozzle for liquid crystal dripping in a central area. The liquid crystal dripping device comprises the liquid crystal dripping nozzle, a support and a disperser arranged on the support, and the liquid crystal dripping nozzle is arranged on an operating end face of the disperser. The liquid crystal dripping method includes: performing liquid crystal dripping in the central area of a liquid crystal pattern through the main dripping nozzle; switching the main dripping nozzle with the auxiliary dripping nozzles; performing liquid crystal dripping in the marginal areas of the liquid crystal pattern through the auxiliary dripping nozzles, wherein the total liquid crystal dripping amount of the auxiliary dripping nozzles is equal to the liquid crystal dripping amount of the main dripping nozzle. The liquid crystal dripping nozzle, the liquid crystal dripping device and the liquid crystal dripping method can be applied to the technical field of display to effectively solve problems of corner light leakage and proneness to puncture of existing dripping devices.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal drip nozzle, a liquid crystal dropping device, and a liquid crystal dropping method. Background technique [0002] In the prior art, the thin film transistor display (TFT-LCD) technology has been developed in recent decades, and the technology and process are becoming more and more mature. With the development of the TFT-LCD industry, the competition of liquid crystal display products is becoming increasingly fierce, and all manufacturers are adopting new technologies to improve the competitiveness of their products in the market. [0003] The liquid crystal (LC) dripping method in traditional liquid crystal display (LCD) products mostly adopts the averaged "I-shaped" mode, that is, the corresponding liquid crystal pattern (LC Pattern) is designed according to the product specification, and the target LC amount is averaged to each drop on Pattern. Th...
