Laser pattern device and laser pattern optical mesh of invisible sensor layer of touch panel

Abstract

The names of the invention are a laser pattern device and a laser pattern optical mesh of an invisible sensor layer of a touch panel. The laser pattern device of the invisible sensor layer of the touch panel comprises a loading unit, a deposition unit, a laser unit and an etching unit; the loading unit is provided with a substrate; a sensor layer is formed by the deposition unit on the substrate; the laser unit performs the laser annealing treatment on a bent anti-interference patch pattern and a sensor layer predetermined pattern of the sensor layer to form a structure changing layer; and the etching unit removes the part of sensor layer except the anti-interference patch pattern and the sensor layer predetermined pattern to form the invisible sensor layer of the touch panel. The laser pattern device provided by the invention can obtain relatively accurate transfer patterns, and can avoid the problems of the common situation that the substrate is likely to be bent, damaged or polluted caused by the fact that the substrate is sent to an oven to be annealed.

Description

【Technical field】 [0001] The invention relates to a laser patterning technology, in particular to a laser patterning device and a laser patterning grid of an invisible sensing layer of a touch panel. 【Background technique】 [0002] In recent years, touch technology has gradually been widely used in general consumer electronics products, such as mobile communication devices, digital cameras, digital music players (MP3), personal digital assistants (PDA), satellite navigation devices (GPS), Hand-held PCs (hand-held PCs), tablet PCs (tablets), and even brand-new super mobile computers (UltraMobilePC, UMPC), etc. Touch technology can be applied to the display panel in various forms, such as adding a touch panel on the display panel (plug-in type), or making a touch sensing unit directly on the display panel (embedded type, also divided into on -cell and in-cell). [0003] However, the process of making the touch sensing unit needs to be formed through film formation, exposure,...
