Detailed description of the invention
With embodiment, the present invention is described in more detail below in conjunction with the accompanying drawings.
The invention discloses a kind of monolayer multi-touch function sheet, arrange the most parallel as it is shown in figure 1, it includes
Multiple electrode groups 1, described electrode group 1 includes multiple electrode 2, and described electrode 2 is provided with wire 3, adjacent two electrode groups 1 it
Between be formed with cabling district, described cabling district is for drawing the wire 3 of its upper electrode 2, and the wire of adjacent two electrode groups 1
3 lead direction are contrary, and in described electrode group 1, the area of multiple electrodes 2 successively decreases successively along wire 3 lead direction.
Compared to existing technologies, the present invention preferably saves the cabling space between induction electrode, reduces life
The requirement of production. art, effectively reduces touch blind area, improves precision, can realize multi-point touch simultaneously.
Further, described electrode 2 is square-shaped electrode.Described wire 3 is drawn by the base of electrode 2.Described electrode 2 uses
Self-capacitance mode drives.When described monolayer multi-touch function sheet is used as transparent touch-sensitive panel, described electrode 2 is by ITO, IZO, nanometer
Silver or carbon nano-tube material are made, the ITO material that preferential selection is conventional.By contrast, described monolayer multi-touch function sheet is used
When making transparent touch panel, described electrode 2 and wire 3 are made up of chromium, copper, aluminum, ITO, IZO, nanometer silver or carbon nano-tube material, excellent
First select conventional copper product.
In the present embodiment, functional sheet is monolayer induction electrode functional sheet, and electrode is square or is approximately square, and electrode is square
Battle array is distributed on functional sheet, and in each electrode group, the induction area of electrode gradually successively decreases along its outlet direction gone between, with cabling
Space between two electrodes separated gradually is incremented by along outlet direction, as it is shown in figure 1, the 1st group of electrode is from left to right along walking
Line direction electrode area gradually successively decreases, and the space of the electrode between two row is gradually incremented by from A1 to A2；Drawing of each induction electrode
Line is close to a wherein limit of this electrode along direction of routing, and binding point is one of them angle P1 of electrode, goes between closely along being somebody's turn to do
Square following limit cabling.The adjacent outlet direction between electrode group is contrary.Outlet direction such as the 1st group is
The positive direction of x, the opposite direction that outlet is x of the 2nd group, it is assumed that the positive direction that outlet direction is x of the 1st group of electrode, then 2n
Group electrode the opposite direction that outlet direction is x, the positive direction that outlet direction is x of 2n+1 group electrode, wherein n for be more than or etc.
In the integer of 0.Use the touch function sheet of the above scheme, except most regions (such as A2) drawn by wire, other region
All there is minimizing in various degree blind area, and the blind area width in some region even decreases several times, such as A1 region.
Monolayer multi-touch function sheet based on said structure, the invention also discloses its touch coordinate acquisition methods, its
In, the touch coordinate X equation below on described monolayer multi-touch function sheet draws:

Touch variable quantity the biggest.When finger touching is near electrode 32, owing to the area of electrode 21 is relatively small, calculating x direction
The value of C21 will be amplified during barycentric coodinates, it is assumed that area ratio electrode 21: electrode 22: electrode 23=1:2:4, then calculate center of gravity
Respectively C21, C22 being adjusted to 4*C21,2C22 during coordinate, C23 is constant.Electrode 31,32,33,41,42 and 43 is the most simultaneously
Needing to be adjusted according to its area ratio relation, the ratio of adjustment is with the electrode of area maximum in touch computing unit for ginseng
Examine, be amplified processing to Ci divided by the numerical value of front electrode area according to maximum area.Calculated by the above coordinate and adjust
Whole, eliminate the unequal touch precision problem caused of electrode area.Described functional sheet is the distribution of multi-electrode matrix form, therefore can
Realize multi-point touch.
The above is preferred embodiment of the present invention, is not limited to the present invention, all technology models in the present invention
Enclose interior done amendment, equivalent or improvement etc., should be included in the range of the present invention protected.
