Description

The slim touching glass module of tool flanging

Technical field

The utility model, about a kind of slim touching glass module of tool flanging, refers in particular to a kind of slim touching glass modular structure that is used in projected capacitive contact surface plate.

Background technology

Touch now screen (display) and can divide into liquid crystal display module and touching glass module two large classes, wherein be responsible for the roughly the same (not shown) of liquid crystal display module structure of display frame, be responsible for touch points position to be converted to the touching glass modular structure of electric signal, according to its principle adopting, as: resistance-type, optical sensing type or capacitance type structure but difference are a lot of.

For the capacitor-type touch glass module of main flow, according to its principle adopting and structure thereof, roughly divide into surface capacitance type, two kinds of glass touch module of transmission condenser type.

As shown in Figure 1, this surface capacitance type touching glass module is mainly set up induction electrode 2 at the corner of touching glass 1, and 2 pairs of touch-control glass 1 surfaces of these induction electrodes apply identical voltage, make touch-control glass 1 surface form a uniform electric field; When finger produces touch points (contact point) on touching glass 1 surface, touching glass 1 surface forms capacitive coupling between can and pointing and then generation current changes, the induction electrode 2 in order touching glass 1 corner converses touch points to the distance in each corner according to the current value of autonomous induction, extrapolates correct touch points.

As shown in Figure 2 to Figure 3, this transmission capacitor-type touch glass module and aforementioned maximum difference exist: this transmission condenser type is set up X-axis ITO inductive layer 11, Y-axis ITO inductive layer 12 below touching glass 1, wherein on X-axis ITO inductive layer 11 and Y-axis ITO inductive layer 12, be arranged with a plurality of along the equidistant X rhombus induction electrode 111 arranging of first direction and a plurality of along the equidistant Y rhombus induction electrode 121 arranging of second direction, and X rhombus induction electrode 111 and 121 settings interlaced with each other of Y rhombus induction electrode, when finger produces touch points (contact point) on touching glass 1 surface, to should touch points the X-axis ITO inductive layer 11 of below and the X rhombus induction electrode 111 of 12 of Y-axis ITO inductive layers and Y rhombus induction electrode 121 can and finger between form capacitive coupling generation current and change and produce and respond to.

During aforesaid projected capacitive touching glass module actual production, mainly by glass (touching glass) and glass (lower floor's glass substrate), folder is encapsulated, that is this transmission capacitor-type touch glass is sequentially superimposed and be encapsulated as a touching glass module (as shown in Figure 3) and be assembled into a touching screen (not shown) with aforesaid liquid crystal display module more each other by a touching glass 1, an X-axis ITO inductive layer 11, an insulation course P, a Y-axis ITO inductive layer 12 and lower floor's glass substrate 13 respectively from top to bottom.

Along with electronic product with rapid changepl. never-ending changes and improvements progressive, the touching glass of projected capacitive touching glass module is by extremely single flanging or the tool flanging moulding (as shown in Figure 4) of many flangings of conventional planar shape form development, this tempered glass can be coated the adjacent side to electronic product with electronic product moulding bending, order touching screen also can extend to its side display frame by electronic product front, but single folding or many flangings (being called for short the moulding of tool flanging) tempered glass 1, must first with hot pressing mode, be configured as after tool flanging (list is rolled over or rolled over more), again with an X-axis ITO inductive layer 11, one insulation course P, one Y-axis ITO inductive layer 12Ji lower floor glass substrate 13 superimposed being packaged as a whole, the awkward situation that while but often causing this touching glass module, actual (real) thickness is blocked up and laminating rate is not good (yield only has 60～70%), light for pursuing, thin, short, the electronic product of little moulding aesthetic feeling and high yield, blocked up this touching glass module and low laminating rate seriously affect production efficiency and quality thereof.

For solving the blocked up problem of this touching glass module, though have dealer that three layers of one X-axis ITO inductive layer 11, an insulation course P, Y-axis ITO inductive layers 12 etc. are effectively integrated and be reduced to individual layer, cannot offset with glass (the touching glass 1) problem blocked up with glass (lower floor's glass substrate 13) the module thickness that clip-on packaged type was produced.

For this reason, how by tool flanging touching glass module thickness effectively thinning be the problem of studying intensively for the utility model.
