Liquid crystal dropping device

Abstract

The invention provides a liquid crystal dropping device, which belongs to the technical field of display. Wherein, the liquid crystal dripping device includes a liquid crystal container, a delivery pipeline and a liquid crystal dropping nozzle, the liquid crystal container is used to hold solid liquid crystal particles, and each solid liquid crystal particle has a fixed weight; the liquid crystal dropping nozzle passes through the delivery tube The road communicates with the liquid crystal container, and the liquid crystal dropping nozzle is used to draw the solid liquid crystal particles from the liquid crystal container and drop the solid liquid crystal particles onto the display substrate; the liquid crystal dropping device also includes: A counter for counting the number of solid liquid crystal particles dropped by the liquid crystal dropping nozzle. The technical scheme of the invention can realize precise control of the liquid crystal dropping amount at a lower cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal dropping device. Background technique [0002] In recent years, with the development of TFT-LCD technology, the size of liquid crystal displays has also developed from medium size to large size and small size, and large and small size liquid crystal displays have also been widely used. With the expansion of the application fields of liquid crystal displays, people have put forward higher and higher requirements for key technical indicators such as response time and viewing angle of liquid crystal displays. [0003] In order to achieve a fast response, the easiest way is to make the box thickness smaller. In order to achieve a wide viewing angle, most manufacturers adopt multi-domain vertical alignment (MVA) and in-plane alignment (IPS) technologies. However, conventional vacuum infusion processes limit the application of these techniques. The vacuum infusion ...

Problems solved by technology

This technology requires very precise movement distance of the piston rod and high flatness for the liquid crystal absorbing container to ensure that the piston rod moves the same distance each time, so that the quality of the dropped liquid crystal is the same, and requires a high-precision balance to verify at all times , because high-precision parts are easy to wear in actual production and use, the dripping accuracy will drop a lot after a period of use, the stability is poor, and high-precision parts need to be replaced frequently, and the cost is high
