1.1 any substrate of the upper and lower substrate that selection prepares uses and drips the glue device on the binding face of this substrate, instillation glue, and make the glue that is instiled be continuous open line segment;
1.2 another baseplate-laminating is had on the substrate of glue to dripping;
1.3 after treating the glue diffusion of described instillation and being full of the binding face of described substrate, with the glue curing that instils.
More specifically, in carry out step 1.1, making described open line segment is one or two crossing straight-line segments, further, makes described two straight-line segments be cruciform.
Or in carry out step 1.1, making described open line segment is the radial straight-line segment that intersects at same point more than three or three, further, makes described straight-line segment be four and is the radial straight-line segment that M shape distributes.
Described glue can be selected ultraviolet hardening glue or heat-curing type glue for use.
The applying method of condenser type touch screen substrate provided by the present invention, change the mode of existing unordered instillation glue, and adopt the glue make instillation to be the mode of continuous open line segment, especially make the glue of instillation be many continuous, the mode that intersects at the radial straight-line segment line of the same point upper and lower base plate of fitting, like this, be positioned at the space between glue on the baseplate-laminating face, from the center of binding face or intersection point of line segments to the edge of baseplate-laminating face gradually, enlarge in an orderly manner, thereby, can rely on glue diffusion itself, levelling, be covered with binding face process and in an orderly manner to the outside natural exhaust of binding face, gas sealed possibility on substrate reduces, residual number of bubbles significantly reduces, therefore, has the raising product quality, yield rate and advantage such as simple.
