Abstract
The invention discloses a capacitive touch screen capable of slowing down light interference effectively. The capacitive touch screen comprises a transparent conductive layer which is made of indium and tin metal oxides, and circuits are etched at central lines of control terminals through the transparent conductive layer. The widths of the circuits are in a range of 0.005mm-0.1m and unevenly arranged on a circuit board. The intervals among lines of the circuits range from 0.015mm to 0.02mm, and an optimum value is 0.015mm. According to the capacitive touch screen, design requirements in a production process are met by changing widths of the circuits and gaps among lines, line breaking is not easy to happen, and grating interference fringes are effectively decreased simultaneously.
Description
Technical field
The present invention relates to a kind of capacitive touch screen, relate in particular to a kind of capacitive touch screen that can effectively slow down 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 produces grating interference strip easily in capacitive touch screen uses, also owing to line when connecting up is thinner, cause easily the problem of broken string.
Summary of the invention
The technical problem to be solved in the present invention has been to provide a kind of live width, minimizing line and distance between centers of tracks of strengthening to weaken the capacitive touch screen design scheme of grating interference strip.
For solving the problems of the technologies described above, the present invention realizes by following scheme: a kind of capacitive touch screen that effectively slows down the interference of light, described capacitive 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.
Advantage of the present invention is: by the width of change circuit and the spacing of line and line, and the designing requirement when producing to satisfy, the problem that is not easy to break is effectively slowed down the interference of light simultaneously and line impedence diminishes.
Description of drawings
Below in conjunction with accompanying drawing the present invention is elaborated.
Fig. 1 is conventional condenser touch-screen partial enlarged drawing;
Fig. 2 is capacitive touch screen partial enlarged drawing of the present invention.
Embodiment
Conventional condenser touch-screen as shown in Figure 1, the width of traditional circuit (40) is generally interval at 0.03mm～0.08mm, for example: traditional circuit (40) live width is 0.03mm, other traditional circuit (40) live width also is 0.03mm on circuit board, and the fixed value of the spacing 30 of its line and line more than 0.03mm is arranged in the circuit uniformly, such design produces grating interference strip easily when capacitive touch screen uses, aborning because the part live width is thinner, cause the problem of broken string in addition.
As shown in Figure 2, a kind of capacitive touch screen that effectively slows down the interference of light, comprise transparency conducting layer, this transparency conducting layer is indium tin metal oxide, etch circuit (20) in control end 50 midline by transparency conducting layer, described circuit (20) live width is interval at 0.05mm～0.1mm, and circuit (20) distance between centers of tracks (10) is that 0.015mm～0.02mm is interval, and 0.015mm is optimum spacing.For example: circuit (20) live width is 0.06mm, but 0.06mm is not fixed value, other circuit (20) live width can be established 0.08mm or other value at 0.05mm～0.1mm, and circuit (20) distance between centers of tracks (10) is that 0.015mm～0.02mm is interval, and 0.015mm is optimum spacing.By this design, the designing requirement when satisfying in the production run is not easy again the problem that breaks.
Simultaneously the present invention design also can effectively reduce the line resistance of circuit, 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 the former technology of above-mentioned formula contrast and present technique, the circuit of former technology (40) live width scope is that 0.03mm～0.08mm is interval, and the circuit of present technique (20) live width scope is 0.05mm～0.1mm interval, if when contrast is found all to get maximal value: D
ThisD
Former, therefore having increased circuit (20) live width D by the present invention, former technology and present technique are at length L, the sheet resistance value R of wire simultaneously
Sheet resistanceAll less than changing, therefore will reduce the line resistance R of circuit by present technique
S
The above only is preferred implementation of the present invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes instructions of the present invention 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 invention.
