Description

Touch-control module

Technical field

The present invention relates to a kind of touch-control module, particularly relate to a kind of utilization and fill unit to solve the touch-control module of the aberration problem of touch-control module.

Background technology

Because one chip glass solution (OneGlassSolution, OGS) of touch panel module is to be set directly at by touch sensing on protection glass, so one chip glass solution can reduce cost and the thickness of touch panel module. Therefore, one chip glass solution will become the main flow of touch panel module solution in future by having an opportunity.

But in the prior art, one chip glass solution still has following point: if the first X-axis sensing unit and Y-axis sensing unit are provided in same layer, then X-axis sensing unit must utilize bridge formation isolation X-axis sensing unit and Y-axis sensing unit with the intersection of Y-axis sensing unit, but build bridge the technological level improving one chip glass solution, increase the manufacturing time of one chip glass solution and reduce the yield of one chip glass solution; The second, because different material has different refractive indexs, if so X-axis sensing unit and Y-axis sensing unit are separately positioned on different layers, then one chip glass solution will have the problem of aberration.

As it is shown in figure 1, existing one chip glass solution has the problem that yield is low. After forming X-axis sensing unit layer 10 on substrate, it is necessary to coating insulating barrier 20 on X-axis sensing unit layer 10. But because X-axis sensing unit 10 has thickness, so the problem that insulating barrier 20 has flatness. Now, when on sputter or attaching Y-axis sensing unit 30 to insulating barrier 20, Y-axis sensing unit 30 is by more out-of-flatness. Owing to the flatness of Y-axis sensing unit 30 is very poor, so the yield of existing one chip glass solution will seriously be affected.

Therefore, for one chip glass solution, prior art is not a good selection.
