Description

APR plate and printing device
Technical Field
The invention relates to the technical field of display, in particular to an APR (advanced photo register) plate and a printing device.
Background
The APR version, also known as relief printing, soft printing, cylinder leather, is commonly used in written language. APR is an abbreviation for ASAHIKASEI PHOTOSENSITIVE RESIN (photosensitive resin developed by asahi corporation in japan); the APR version refers to the generic term liquid plate and later relief plate.
The APR plate is mainly used for roller printing of an alignment Liquid in processes of a TN panel/STN panel/C-STN panel/TFT panel (twisted nematic panel/super twisted nematic panel/color super twisted nematic panel/thin film field effect transistor panel) in the Liquid Crystal Display (LCD) industry, that is, the alignment Liquid is transferred onto a glass substrate to form a uniform alignment Liquid coating. By adopting the APR plate, a high-quality product with good dot depth and dot uniformity can be provided according to customer requirements, so that the thickness of the directional liquid film layer of transfer printing is uniform, and the quality of the product is ensured.
In order to ensure the precision of Polyimide (PI) film formation, printing is usually performed by Coating, i.e., PI liquid is attached to a special APR plate with a high-precision fixed size, and then the plate is transferred to glass. The APR plate adsorbs PI liquid in a mesh mode, and the PI liquid is extruded out of the mesh and transferred to glass during printing. In order to save space and improve the operability of the equipment, the APR plate is designed to be wound on a transfer roller and roll-printed from the printing starting end to the printing tail end, so that one printing operation of the APR plate is completed.
As shown in fig. 1, the APR plate 200 includes a substrate 210 and a printing pattern layer 220 disposed on the substrate 210, and when the APR plate 200 is actually used, the transfer roller 300 rotates to press and deform the APR plate 200 and the glass substrate 100, so as to transfer the PI solution adsorbed on the APR plate 200 onto the glass substrate 100, and for the press deformation, the NIP value, i.e., the width of the APR plate 200 contacting the glass substrate 100, is used in the industry to describe the deformation degree. As shown in fig. 2, when the printing pattern layer 220 of the APR plate 200 is separated from the glass substrate 100, the end of the printing pattern layer 220 may scratch against the printed PI film surface, so as to form an influence region having a width about half of the NIP value, that is, the formed PI film generates Mura.
