Being adjusted with vertical pivot Y-axis, wherein, TP (TOUCH PANEL, i.e. touch screen) is used for representing touch screen.Adjust with X-direction below
As a example by whole, Tuning function or adjustment table (Y direction method of adjustment is similar) can be got by following steps.
Step S11, finds out the cycle of the X-direction of the pattern needing the touch screen revised to use.
The pattern design of general touch screen is all to have periodically, i.e. figure is that many groups are same or like
Sensor be stitched together formed pattern.The cycle of general conventional figure is exactly 1 or 2 passages.
Fig. 3 is the schematic diagram of a kind of typical monolayer figure according to embodiments of the present invention.In Fig. 3 with X1, X2, X3, X4,
X5, X6, X7, X8 and X9 represent abscissa, represent vertical coordinate with Y1, Y2, Y3, Y4, Y5, Y6, Y7 and Y8, and Fig. 3 is only with 9 horizontal seats
As a example by 72 points that mark and 8 vertical coordinates show, the embodiment of the present invention is described in detail in detail, as shown in Figure 3: each coordinate points all includes sending
Module and receiver module, as coordinate points (X1, Y1) includes sending module TX1 and receiver module RX1, wherein, TX (transmit,
I.e. send) represent that sending module, RX (Receive, i.e. receive) represent receiver module, figure respectively illustrates 8 sending modules:
TX1, TX2, TX3, TX4, TX5, TX6, TX7 and TX8, respectively illustrate 9 receiver module: RX1, RX2, RX3, RX4, RX5,
RX6, RX7, RX8 and RX9.Wherein, the passage that the entirety of receiver module and transmitter module one repeats, i.e. receiver module and transmitting
Module is to repeat in the cycle from Xn-1 to Xn and between Xn to Xn+1, and 1 ＜ n≤8, n is integer.
At this, we choose M group, and wherein, M is integer, M ＞ 0.Assume this example to select 1 group (the most do not select edge
Passage, edge gateway data are imperfect), such as X3.
Step S22, to the often group N decile selected, wherein, N is integer, N ＞ 0.As shown in Figure 4, the one group of X3 that will select
Carry out N decile (such as eight equal parts), and the abscissa X3 after eight equal parts be finely divided, be respectively designated as X3, X31, X32, X33,
X34, X35, X36 and X37, wherein, N can pre-set.
Step S33, respectively along X3, X31 ... X37 draws 8 vertical lines, and records the X-coordinate corresponding to every vertical line.
Assume that along X-axis coordinate during X3 picture vertical line be POSX (3,0) respectively, POSX (3,1) ... POSX (3, K)；
It is POSX (31,0) respectively along X-axis coordinate during X31 picture vertical line, POSX (31,1) ... POSX (31, K)；
…
It is POSX (37,0) respectively along X-axis coordinate during X37 picture vertical line, POSX (37,1) ... POSX (37, K)；
Wherein, POSX represents X-axis coordinate, and K is natural number, in the present embodiment K=7.
The coordinate recorded is processed and obtains the X-axis coordinate that corresponding every vertical line is corresponding.General process includes removing
The coordinate that obvious deviation is bigger, takes intermediate value or meansigma methods to remaining coordinate.Citing uses the mode of meansigma methods to obtain
POSX3=average (POSX (3,0), POSX (3,1) ... POSX (3, K))；
POSX31=average (POSX (31,0), POSX (31,1) ... POSX (31, K))；
…
POSX37=average (POSX (37,0), POSX (37,1) ... POSX (37, K))；
Wherein, average () expression is averaged.
As, POSX3=average (POSX (3,0), POSX (3,1) ... POSX (3, K)) represents POSX (3,0), POSX
(3,1) ... POSX (3, K) this (K+1) individual point is averaged, wherein, K=7.
Step S44, calculates and obtains theoretical coordinate.Assume that the pixel that each passage is corresponding is R, then: the theoretical seat that X1 is corresponding
Being designated as: 0, X2 corresponding theoretical coordinate is: the theoretical coordinate that R, Xn are corresponding is: (n-1) * R, wherein, n is natural number, real at this
Execute n≤9 in example.Thus can extrapolate:
Theoretical coordinate POSX3 corresponding for X3 is: 2R
Theoretical coordinate corresponding for X31 is: 2R+R/8
Theoretical coordinate corresponding for X32 is: 2R+2R/8
…
Theoretical coordinate corresponding for X37 is: 2R+7R/8
Theoretical coordinate corresponding for X4 is: 3R
Scheme one: process full frame the most by the above process, obtains the actual coordinate of all vertical lines, and extrapolates all perpendicular
The theoretical coordinate of line, then utilizes linear fit, or table look-up actual coordinate is converted into theoretical coordinate, result such as Fig. 5 institute
Showing, in Fig. 5, abscissa X represents actual X-coordinate, and vertical coordinate Comp (X) represents the X-coordinate after calculating, the efficiency of the program is relatively
Low.
Scheme two, utilizes the periodicity of figure, it is known that as long as we are by good for the compensation deals in the cycle, available week
Phase characteristic expands to full frame.Hereinafter the compensation in the cycle is only considered,
Step S55, carries out mould by the actual coordinate of every line to pixel R and removes, obtain X1, X2 ... .X9, wherein,
X1=POSX3modR
X2=POSX31modR
X3=POSX32modR
…
X8=POSX37modR
X9=POSX4modR
Bringing result above into rectangular coordinate system, according to these characteristic points, carry out linear fit, available penalty function is bent
Line Comp (X), as shown in Figure 6, X-axis represents abscissa, and vertical coordinate Comp (X) represents the abscissa after compensating.
Expanding to full frame below equation: Pos (x)=int (x/R) the * R+Comp (xmodR) that can utilize, wherein, x is real
The calculated coordinate in border, Pos (x) is the coordinate after compensating, and int () is for dividing exactly, and mod is that mould removes, and Comp () is penalty function
The curve compensation effect being it desired to matching is more preferable, can choose several passage more and go to obtain doing same process,
Then the characteristic point obtained is averaged.
