Problems solved by technology

[0008] Although the traditional degassing method of adding a stirring rod can accelerate the degassing, it will greatly increase the content of impurities with a size above 5 μm, so it is not an ideal degassing method for the drop-in liquid crystal filling process (ODF)

Embodiment Construction

[0045] Figure 2A It is a schematic diagram showing the defoaming system for reducing the contamination of liquid crystal in the present invention. As shown in the figure, the liquid crystal defoaming system of the present invention includes a vacuum chamber 1 and a liquid crystal defoaming device 2 . The liquid crystal defoaming device 2 is arranged in the vacuum chamber 1 and is used for defoaming the liquid crystal.

[0046] Please also refer to Figure 2A and 2B, where Figure 2B It is a schematic diagram which shows the said liquid crystal defoaming apparatus 2. The liquid crystal defoaming system of this embodiment can be applied to the drop-injection liquid crystal perfusion process (ODF). As shown in the figure, the liquid crystal defoaming device 2 of the present invention mainly includes a base 21 , a container 22 and an ultrasonic generator device 23. The base 21 has a concave portion 211, and the container 22 is placed on the base 21 and located in the concave ...

Abstract

The liquid crystal debubbling system with reduced contamination includes one vacuum chamber and one liquid crystal debubbling device. The liquid crystal debubbling device set inside the vacuum chamber includes one pedestal, one holding container and one ultrasonic wave generator, the holding container is set on the pedestal for holding the liquid crystal, and the ultrasonic wave generator is used to send one ultrasonic wave to the liquid crystal and form vacuum bubbles inside the liquid crystal.

Description

technical field [0001] The invention relates to a liquid crystal defoaming system and a liquid crystal defoaming method, in particular to a defoaming system and a defoaming method which utilize ultrasonic waves to improve the defoaming effect and can reduce liquid crystal pollution. Background technique [0002] Generally speaking, in the manufacturing process of the existing liquid crystal display, the liquid crystal must be injected between the two substrates first, and the liquid crystal is slowly sucked in by the capillary principle, but this method of filling the liquid crystal is quite time-consuming. Another drip-type liquid crystal perfusion process (ODF) directly drips liquid crystal on a single substrate, and then aligns the upper and lower substrates. The drip-type liquid crystal perfusion process can greatly save the time for liquid crystal filling, especially suitable for for large-sized panels. Taking the 30 o'clock panel as an example, the traditional liquid ...
