Abstract
The utility model discloses a kind of liquid crystal display jumper wire construction, comprise glassy layer and ITO layer, ITO layer is provided with drive electrode block and the induction electrode block of multiple longitudinally setting, all gap is left between adjacent drive electrode block and induction electrode block, described gap is finger contact area, drive electrode block and induction electrode block are strip, each drive electrode block is provided with horizontal convex section, each induction electrode block is provided with the recessed section corresponded, and each drive electrode block is all connected with conductive pin with the end of induction electrode block.Liquid crystal display jumper wire construction of the present utility model changes individual layer ITO in the past can only realize single-point touch and the open defect at multiple point touching, when many finger touch, accurately and fast can quote coordinate points, the touch effect of double-deck ITO structure can be reached, simultaneously, manufacture cost and operation reduces greatly, be conducive to the manufacturing of capacitive touch screen.
Description
Technical field
The utility model relates to a kind of jumper wire construction of liquid crystal display.
Background technology
Electric capacity liquid crystal touch screen is generally divided into GF capacitance touch screen and GFF capacitance touch screen.
GFF capacitance touch screen, is two-layer mutual capacitance touchscreens, can multi-point touch really.But need two-layer laying electrode pad, the large multiplex transparent conductive material ITO of this electrode pad makes, production cost process CIMS is complicated, and cost is higher.
GF capacitance touch screen, be individual layer mutual capacitance touchscreens, individual layer ITO can be used to do the electrode of mutual capacitance, a kind of battery lead plate is arranged in the gap between another kind of battery lead plate, electrode with a line is connected to external of screen by transparent ITO lead-in wire, then in the outside touching effective district correspondence with the Electrode connection of a line to together.The technique of individual layer mutual capacitance touchscreens and cost will simplify than traditional two-layer mutual capacitance, but its electrode pattern more complicated, the line connected outside the effective district of touch-screen is very many, proposes high requirement to the precision of production technology, produces yield simultaneously and also can give a discount.Wherein electrode pattern is the most simply use complementary class triangular-shaped electrodes to form.But adopt the self-capacitance touch screen of this kind triangle complementary patterns to touch rate of change coordinates computed owing to adopting in the horizontal direction the computing method of touch point coordinate data, adopt at vertical direction and touch change center of gravity calculation coordinate, can not multi-point touch be realized in some cases.Therefore, traditional wire structures can only realize false 2 points, namely can realize two point operations in most of region, and can only single-point operation in the horizontal direction or in vertical direction, larger to the application restriction ratio of mobile phone.
Utility model content
The jumper wire construction of that the utility model provides a kind of low cost, that multiple point touching can be realized liquid crystal display.
Liquid crystal display jumper wire construction described in the utility model, comprise glassy layer and ITO layer, ITO layer is provided with drive electrode block and the induction electrode block of multiple longitudinally setting, all gap is left between adjacent drive electrode block and induction electrode block, described gap is finger contact area, drive electrode block and induction electrode block are strip, each drive electrode block is provided with horizontal convex section, each induction electrode block is provided with the recessed section corresponded, and each drive electrode block is all connected with conductive pin with the end of induction electrode block.
The jumper wire construction of liquid crystal display described in the utility model, when touching drive electrode block and induction electrode block with finger simultaneously, immediately realizes the current lead-through between conductive pin, can distinguish finger position.The recessed section that drive electrode block is provided with horizontal convex section and induction electrode block can more prepare to distinguish vertical and horizontal position.Change individual layer ITO in the past and can only realize single-point touch and the open defect at multiple point touching, when many finger touch, accurately and fast can quote coordinate points, the touch effect of double-deck ITO structure can be reached.Meanwhile, during production, only need individual layer ITO to realize multiple point touching, manufacture cost and operation reduces greatly, be conducive to the manufacturing of electric capacity liquid crystal touch screen.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of jumper wire construction of liquid crystal display.
Embodiment
As shown in Figure 1, a kind of jumper wire construction of liquid crystal display comprises glassy layer 1 and ITO layer 2, ITO layer 2 is provided with drive electrode block 3 and the induction electrode block 4 of multiple longitudinally setting, all gap is left between adjacent drive electrode block 3 and induction electrode block 4, described gap is finger contact area, drive electrode block 3 and induction electrode block 4 are strip, the drive electrode block of each strip is provided with multiple horizontal convex section, each induction electrode block is provided with the recessed section corresponded, each drive electrode block is all connected with conductive pin 5 with the end of induction electrode block, conductive pin is connected with the circuit on flexible PCB 6.Touch drive electrode block and induction electrode block with finger simultaneously, immediately realize the current lead-through between conductive pin, can finger position be distinguished.The recessed section that drive electrode block is provided with horizontal convex section and induction electrode block can more prepare to distinguish vertical and horizontal position.
Wherein, drive electrode block intersects mutually with induction electrode block, can increase the sensitivity of finger touch liquid crystal display, and finger can be allowed to be more prone to touch the drive electrode block in ITO layer and induction electrode block simultaneously.
The edge of adjacent driven electrode block and induction electrode block is parallel to each other, and can ensure that the clearance distance between drive electrode block and induction electrode block is consistent, and is more conducive to the position accurately identifying finger touch.
