Problems solved by technology

[0007] The purpose of the present invention is to provide a liquid crystal coating device and method. By adding a gas cooling device that moves synchronously with the liquid crystal nozzle to the liquid crystal coating device, when the liquid crystal is coated, the gas cooling device will move toward the substrate along the track of the liquid crystal coating. The coated liquid crystal sprays out high-purity low-temperature drying gas, which promotes the rapid cooling of the liquid crystal and prevents its diffusion from contacting the sealant, which effectively solves the problem that the liquid crystal dripped on the substrate in the prior art diffuses too fast and is not compatible with the seal. The problem of dissolution type pollution caused by the contact of the frame glue

Embodiment 1

[0032] Such as figure 1 As shown, a liquid crystal coating device described in this embodiment includes a liquid crystal shower head 3 for coating liquid crystal 2 and a gas cooling device 6 for cooling the coated liquid crystal 2, and the gas cooling device 6 Located behind the liquid crystal shower head 3 and moving along the trajectory of the liquid crystal shower head 3, the liquid crystal shower head 3 ejects liquid crystal through its nozzle 4, and the gas cooling device 6 cools the liquid crystal 2 rapidly.

[0033] The gas cooling device 6 includes an air circuit system 63 and an air injection chamber 61. The air injection chamber 61 communicates with the gas storage device 9 through the air circuit system 63. The gas circuit system 63 is provided with a flow valve for controlling the flow of gas. The flow valve and the flow valve can adjust the size of the gas flow and the temperature of the low-temperature gas, so that the low-temperature gas can be gently applied to...

Embodiment 2

[0039] The liquid crystal coating method described in this embodiment adopts the liquid crystal coating device described in Embodiment 1, and the schematic diagram of the liquid crystal coating device in use is as follows figure 2 shown.

[0040] A kind of liquid crystal coating method described in the present embodiment comprises the following steps:

[0041] S1, through the liquid crystal nozzle 3 figure 2 Spray evenly a set pattern and quantity of liquid crystals 2 on the substrate 1 in the direction shown in ;

[0042] S2. While spraying the liquid crystal 2, the gas cooling device 6 gently sprays high-purity low-temperature dry gas 7 to cool down the liquid crystal 2 on the substrate 1 along the trajectory of the liquid crystal 2 coating, reducing the fluidity of the liquid crystal 2 and increasing the viscosity. Hysteresis coefficient, reducing the diffusion speed of liquid crystal 2;

[0043] S3. Carrying out thermal curing treatment on the frame sealing glue, so t...

Abstract

The invention relates to the technical field of manufacturing liquid crystal panel displays, and discloses a liquid crystal coating device and method. The device includes a liquid crystal shower head and a gas cooling device, the gas cooling device is located behind the liquid crystal shower head and moves along the moving track of the liquid crystal shower head. The method is that when the liquid crystal is coated, the gas cooling device sprays high-purity low-temperature dry gas to the coated liquid crystal on the substrate along the track of the liquid crystal coating, so as to promote the rapid reduction of the temperature of the liquid crystal and avoid its diffusion and sealing glue. touch. A liquid crystal coating device and method provided by the present invention, by adding a gas cooling device that moves synchronously with the liquid crystal spray head to the liquid crystal coating device, effectively solves the problem of too fast diffusion of the liquid crystal dripped on the substrate in the prior art, which is not compatible with the sealing frame After the glue contacts, it will lead to dissolution type pollution, that is, the LCD screen has problems such as yellowing around the LCD screen, afterimages, and broken bright spots.

Description

technical field [0001] The invention relates to the technical field of manufacturing liquid crystal panel displays, in particular to a liquid crystal coating device and a liquid crystal coating method using the device. Background technique [0002] With the development of liquid crystal technology, high-quality, low power consumption, radiation-free thin film transistor liquid crystal display (TFT-LCD) has become the mainstream of the market. [0003] In the cell-forming process of liquid crystal panel manufacturing, liquid crystal filling is a very crucial process. The method is: first fill the liquid crystal between the array substrate and the color filter substrate through a filling device such as inkjet printing equipment, and then pass The frame sealant is vacuum bonded, and finally cut into individual LCD panel units. Usually, in order to reduce the beat, the liquid crystal and the sealant are coated on different substrates respectively. The frame sealant is a transl...
