Problems solved by technology

[0005] At present, the transfer printing plate is attached to the printing roller manually. Since the transfer printing plate is made of resin material, the attachment between it and the printing roller is not strong, which will easily lead to transfer printing when the printing roller transfers printing. Due to the displacement of the plate, the printing accuracy cannot be guaranteed

Abstract

The invention provides a printing roller, which includes: a body, which has an attachment surface for attaching a transfer printing plate, and a plurality of protrusions are uniformly distributed on the attachment surface for absorbing the transfer printing plate. The printing roller provided by the present invention, compared with the transfer printing plate in the prior art that is only attached to the printing roller, has a stronger adsorption force on the transfer printing plate, thereby avoiding the displacement of the transfer printing plate when the printing roller transfers printing , so that the printing accuracy can be guaranteed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a printing roller. Background technique [0002] A liquid crystal display (TFT-LCD) expresses images using the optical properties of liquid crystals that vary with applied voltage, and is composed of a liquid crystal panel and a printed circuit board (PCB) for applying signals to the liquid crystal panel. Among them, the liquid crystal The panel consists of a pair of glass substrates injected with liquid crystals. In order to obtain a liquid crystal display device with uniform brightness and high contrast, it is necessary to arrange the liquid crystal molecules in a certain direction in the liquid crystal panel, and an orientation film (Polyimide, PI) can be used to make the liquid crystal molecules be regularly arranged in a certain direction on the surface. [0003] In the process of making liquid crystal display devices, the alignment layer printing machine prints th...
