Transfer printing plate, display screen, display device and display device manufacturing method

Abstract

The invention provides a transfer printing plate, a display screen, a display device and a display device manufacturing method. The transfer printing plate comprises a printing region and a non-printing region, wherein the printing region comprises multiple sub-printing units corresponding to multiple unit display screens on a mother plate in one-to-one mode, different mark zones are arranged on each sub-printing unit respectively and used for forming marks for identifying the unit display screens on the mother plate on the unit display screens while forming alignment films on the unit display screens on the mother plate. By means of the scheme, the mark zones are set in the printing region of the transfer printing plate through improvement on the transfer printing plate structure, the unit display screens can be simultaneously marked on the same mother plate when the alignment films are formed on the mother plate, and the unit display screen marking efficiency of a current production line is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transfer plate, a display device and a manufacturing method of the display device. Background technique [0002] In the field of display technology, liquid crystal displays are widely used due to their advantages of small size, low power consumption, no radiation, and high resolution. figure 1 is a schematic cross-sectional view of the peripheral area of ​​a liquid crystal display. Such as figure 1 As shown, a general liquid crystal display includes a color filter substrate 10 and an array substrate 20 disposed opposite to each other, and a liquid crystal layer (not shown in the figure) between the two substrates. The surroundings of the color filter substrate 10 and the array substrate 20 are connected by a sealant 30 , the color filter substrate 10 has a black matrix 11 and an alignment film 12 , and the array substrate has an alignment film 12 . Among them, the display a...

AI Technical Summary

Problems solved by technology

When the number of unit displays in a template glass is small, the marking work of Panel ID is relatively simple and occupies less capacity of the production line; but when the number of unit displays on a mother glass is large, the Panel ID The marking work will be more cumbersome and take up more production line capacity

Especially at present, the size of unit displays made by each panel generation line is getting smaller and smaller. There are hundreds of unit displays on the substrate on a mother glass, and the work of marking Panel ID becomes more difficult.

Sometimes, for the consideration of production line capacity, the Panel ID is not marked, so that the problems in the subsequent production process cannot be traced back to the previous process, which greatly reduces the efficiency of the production line
