Abstract
The utility model discloses a capacitive touch screen capable of effectively overcoming light interference. The capacitive touch screen capable of effectively overcoming light interference comprises a transparent conducting layer made of indium-tin metallic oxide, circuits are etched at the center wire position of a control end by the transparent conducting layer, circuit wires with the widths ranging from 0.05mm to 0.1mm are non-uniformly arranged on a circuit board, and the intervals among the circuit wires range from 0.015mm to 0.02mm and are preferably 0.015mm. The capacitive touch screen meets design requirements during production by changing the widths of the circuits and the intervals among the wires, the problem of proneness to wire breakage is avoided, and the problem of grating interference fringes is effectively solved.
Description
Technical field
The utility model relates to a kind of touch-screen, relates in particular to a kind of capacitive touch screen that can effectively solve the elimination grating interference strip.
Background technology
In the prior art, when transparency conducting layer connects up, consider symmetrical and uniform problem, live width is all adopting even live width design near the both sides of control end, the isochrone spacing also is consistent, and distance between centers of tracks generally remains between 0.03mm～0.08mm in the traditional design, and such design easily produces grating interference strip in touch-screen uses, also solved produce in because the part live width is thinner, cause the problem of broken string.
The utility model content
The technical problems to be solved in the utility model has been to provide a kind of capacitive touch screen that strengthens live width, reduces line and distance between centers of tracks.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of capacitive touch screen of effective solution interference of light, described touch-screen comprises transparency conducting layer, etches circuit in the control end midline by transparency conducting layer.
Described circuit live width is in inhomogeneous being arranged on the circuit board of the interval arbitrary value of 0.05mm～0.1mm.
The spacing of described circuit line and line is interval at 0.015mm～0.02mm.
Described transparency conducting layer is indium tin metal oxide.
The utility model has the advantages that: by the width of change circuit and the spacing of line and line, the designing requirement when producing to satisfy, the problem that is not easy to break, effectively the solution interference of light and line impedence diminish simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model capacitive touch screen partial enlarged drawing;
Fig. 2 is conventional condenser touch-screen partial enlarged drawing.
Embodiment
Conventional condenser touch-screen as shown in Figure 2, the width of traditional circuit 10 is generally interval at 0.03mm～0.08mm, for example: traditional circuit 10 live widths are 0.03mm, other traditional circuit 10 live widths also are 0.03mm on circuit board, and the fixed value of the spacing 20 of its line and line more than 0.03mm is arranged in the circuit uniformly, such design easily produces grating interference strip when touch-screen uses, aborning because the part live width is thinner, cause the problem of broken string in addition.
As shown in Figure 1, a kind of capacitive touch screen of effective solution interference of light, comprise transparency conducting layer, this transparency conducting layer is indium tin metal oxide, etch circuit 30 in control end 50 midline by transparency conducting layer, described circuit 30 live widths are interval at 0.05mm～0.1mm, and circuit 30 distance between centers of tracks 40 are that 0.015mm～0.02mm is interval, and 0.015mm is optimum spacing.For example: circuit 30 live widths are 0.06mm, but 0.06mm is not fixed value, and other circuit 30 live widths can be established 0.08mm or other value at 0.05mm～0.1mm.By this design, both can satisfy the designing requirement when producing, be not easy again the problem that breaks.
Simultaneously the utility model design also can effectively reduce the line resistance of conducting wire 30, and is conducive to satisfy the line resistance design of circuit, and its computing formula is: R
S=R
Sheet resistanceMultiply by L/D, wherein: R
SBe the line resistance of wire, R
Sheet resistanceBe the sheet resistance value of this material, L is the length of wire, and D is the width of wire.Can find out from above-mentioned formula, the utility model has increased circuit 30 live width D, the length L of wire, sheet resistance value R
Sheet resistanceBe fixed value, thereby reduced the line resistance R of wire
S, realized that effectively the impedance of circuit 30 diminishes.
The above only is preferred implementation of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
