Mask graph transfer-printing device and method for preparing mask graph

Abstract

The present invention discloses a mask pattern transferring device and a method of preparing a mask pattern transferring device. The mask pattern transferring device comprises: a magnetization head disposed on a magnetization head carrying device, for magnetizing composite powders each comprising a core of ferromagnetic metal and an outer resin film; a rotary roller formed of a non-ferromagnetic material, for adsorbing the composite powders magnetized by the magnetization head; a demagnetization head disposed at a downstream of the magnetization head in the rotating direction of the rotary roller, for demagnetizing the magnetized composite powders adsorbed by the rotary roller; and a collecting container, the outer edge of which is tangent with one side of the rotary roller, and which is disposed at the downstream of the magnetization head along the periphery of the rotary roller to collect the demagnetized composite powders.

Description

technical field [0001] The invention relates to mask forming technology in liquid crystal display, in particular to a mask pattern transferring device and a method for preparing mask pattern. Background technique [0002] A liquid crystal display (LCD for short) is a commonly used flat panel display at present. In the rapid development of the past ten years, LCD has made great progress from the size of the screen to the quality of the display. With the continuous expansion of LCD production, the competition among various manufacturers is becoming increasingly fierce. Manufacturers are constantly improving the performance of LCD products, while also making continuous efforts to reduce production costs, thereby enhancing market competitiveness. [0003] Mask exposure is an essential process in the current LCD manufacturing process. Mask exposure is: by exposing the pattern on the mask plate to the photosensitive photoresist coating prepared by gluing, low-pressure drying, p...

Problems solved by technology

[0004] However, since the preparation of LCD by mask exposure requires the use of multiple mask plates for complete devices, the preparation of mask plates has become one of the reasons for the high production cost of LCD due to its unusually high price; and when the mask plate design It is inconvenient to modify when an error occurs

In addition, due to the need for low-pressure drying, pre-baking, and developing processes in the process of preparing the photoresist coating, the consumables such as developer solution and compressed gas required in these processes also increase the production cost of LCD.
