Description
Technical field
The utility model relate to a kind of on substrate the fixing device of mask, be specifically related to a kind of on substrate the fixing device of mask.
Background technology
Touch-screen is a kind of input unit, can conveniently realize the interaction of people and computer and other portable mobile apparatus.In recent years, be widely used in mobile InterWorking Equipment based on the capacitance touch screen of transparent conductive film, as smart mobile phone, portable panel computer.
Touch-screen is divided into form Touch Zone 2 and lead-in wire electrode district 1 according to functional area, and lead-in wire electrode district 1 connects external structure (Fig. 1 is the functional area synoptic diagram of capacitive touch screen) by controller.Capacitive touch screen is from textural double-disk capacitance touch screen and the one chip capacitance touch screen of being divided into.But no matter the double-disk capacitance touch screen still is the one chip capacitance touch screen, and it all need plate the layer of transparent conductive film layer on substrate.And all need plate long and narrow electrode on four limits of transparent conductive film layer, so that in electrical conductor, form a low voltage alternating-electric field.When touch screen, because people's bulk electric field, can form a coupling capacity between finger and conductor layer, the electric current that four limit electrodes send can flow to the contact, be directly proportional with the distance of pointing electrode and electric current is strong and weak, be positioned at ratio and power that controller after the touch screen just can calculate electric current, accurately calculate touch point position.
In capacitive touch screen, can be the ITO(indium tin oxide as the material of transparent conductive film layer) or Graphene.The transparent conductive film layer that material preparation obtains for ITO, the fragility height is prone to crackle, comes off, and the life-span is short, and can't be used as the substrate of PET material, and the cost height.The ITO transparent conductive film layer can prepare by the mode of sputter coating.Yet, comprising glass sclerosis, ITO plated film, black film, gold-tinted etching, metal coating, wet etching and special-shaped cutting etc. based on the preparation technology of the capacitive touch screen of ITO transparent conductive film, cost is higher, and the yield of product is very low.

(3) utilizing mask directly to form the lead-in wire electrode district in the PVD process is a kind of easier method, but considers that the mask any part all can not block the lead-in wire electrode district, and therefore how fixedly mask is technological difficulties.If can not fix, mask can only horizontal positioned so, thereby the position of having limited the plated film sample has seriously reduced production efficiency.
The preparation of ITO transparent conductive film layer and metallic diaphragm generally adopts the mode of sputter coating to realize.Sputter coating is to utilize energetic ion impact material target, goes out particle and is deposited on film forming method on the workpiece surface from its surface sputtering.
In the preparation process of capacitive touch screen, be covered with the metallic diaphragm that only needs on the substrate of transparent conductive film layer at lead-in wire electrode district coated with conductive as the lead-in wire electrode, send the signal receiver of touch-screen to the touch point signal that the form Touch Zone is received.
