a transfer plate

Abstract

A transfer plate and an orientation film generation system are provided. The transfer plate includes a bottom plate and a plurality of relief plates, wherein, the bottom plate is disposed on a printing cylinder and is distributed with a plurality of engagement holes, each of the engagement holes has a plurality of stopper locations configured to provide different engagement depths; and the plurality of relief plates and the plurality of engagement holes are disposed in one-to-one correspondence, and each of the relief plates is provided with an engagement pin cooperated with the stopper locations of a corresponding engagement hole, wherein the relief plate is made of permeable materials. The orientation film generation system includes the above transfer plate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transfer printing plate. Background technique [0002] In the manufacture of liquid crystal products, the ARP plate (transfer plate) is mainly used for roller coating of alignment liquid (PI, Polyimide, polyimide) in the LCD (liquid crystal display) industry and other processes, that is, to transfer the alignment liquid to the glass substrate. , to form a uniform alignment liquid coating. [0003] Currently, if figure 1 As shown, the general alignment liquid coating process is as follows: first, the nozzle 1 sprays the alignment liquid 1 onto the doctor blade (Doctor) roll 4, and then the Doctor roll 4 transfers the alignment liquid to the anilox (Anilox) roll 3, and then The Anilox roller transfers the alignment liquid to the traditional transfer printing plate 5 on its plate barrel 6, and finally the printing equipment base 7 transports the glass substrate 8 to the bottom ...

AI Technical Summary

Problems solved by technology

[0004] Due to the different requirements for the thickness of the orientation film of different products, for example, in order to ensure that a product has a prominent afterimage effect, a thicker orientation film is generally used; For the sake of cost, normal or thinner oriented film thickness is generally used. In order to meet the needs of different oriented film products, it is generally necessary to replace the Anilox roller or change the mesh depth of the APR plate. Replacing the Anilox roller is time-consuming and labor-intensive, which has a great impact on production capacity. Large; to change the mesh depth of the APR version, it is necessary to re-design the APR version, which is expensive

[0005] In addition, the APR version itself is expensive and occupies a relatively high proportion of the cost of the LCD front-end production process.

In the process of using the APR version, the proportion of APR natural aging is very small, and the proportion of scrapping by external forces accounts for the vast majority. As long as there is a small scratch on the printing surface of the APR version, it cannot continue to be used and must be completed. Replacement, resulting in an increase in production costs and a waste of resources
