Abstract
The invention discloses a method for processing touch screen pressing information of a resistive touch screen, which comprises the following steps of: dividing the touch screen into a plurality of areas; dividing a large screen into small screens, and then adjusting positions of each small screen independently and finely.
Description
Technical field
The touch screen that the present invention relates to a kind of resistive touch screen is pushed information processing method, and especially a kind of touch screen of larger sized resistive touch screen of realizing is pushed the method for information processing.
Background technology
In today of computer technology develop rapidly, occurred multiple computer input methods such as keyboard input, mouse input, voice typing, image acquisition successively, and wherein simple, the most natural a kind of method is directly to carry out information typing, instruction transfer by touching the click mode on computer display.For example, the user needs only the icon or the literal that adopt pointer or finger to touch lightly on the computer display and just can realize computer operation, thereby makes man-machine interaction more simple and direct, and this technology greatly facilitates those users who is ignorant of computation.At present, touching to click to import has become a kind of extremely attractive computer interactive mode, is applied in widely in the various fields such as urban information service, Industry Control, multimedia teaching, tour guide, amusement.
Existing touch-screen mainly still adopts resistance-type, promptly utilizes the pressure perception to control, and (X, physical location Y) are converted to the voltage of representing X coordinate and Y coordinate with touch point in the rectangular area.The main department of resistive touch screen is a resistance film screen that cooperates very much with display screen surface, this is a kind of laminated film of multilayer, it with one deck glass or duroplasts flat board as basic unit, the surface scribbles one deck conductive layer (transparent conductive resistance), lid layer passes through cure process, smooth anti-friction plastic layer more above, its inside surface also scribbles the layer of transparent conductive layer, has many tiny (less than 1/1000 inch) transparent isolating points that two conductive layers is separated insulation between them.When adopting pointer or finger touch screen, two conductive layers has just had contact in the position, touch point, resistance changes, wherein the even voltage field of 5V of a conductive layer connection Y direction makes the voltage of detecting layer become non-zero by zero, after controller detects this connection, carry out the A/D conversion, and the magnitude of voltage that obtains compared the Y-axis coordinate that can obtain the touch point with 5V, and in like manner can draw the coordinate of X-axis, the last mode of analog mouse is again carried out work.
In handheld mobile devices such as most existing smart mobile phone, PDA, UMPC, because screen size is less, can on the predefined fixed position of touch-screen, show the touch area, the user is put into pointer or hand in each step operation and clicks this position on the position of wanting the touch area and get final product like this, also has some handheld mobile devices to realize touching preferably effect by the mode that adopts registration of simple touch area or increase icon size.But for 5 cun even more for the handheld mobile device of large scale screen and operation Windows operating system, the man-machine interactive operation that adopts that resistive touch screen realizes that web page browsing, window drag and drop, outline map punctuate hit etc. and become more meticulous will be a challenging problem.
Summary of the invention
For the touch screen that overcomes existing resistive touch screen is pushed the deficiency that information processing method can not be suitable for larger sized resistive touch screen, the touch screen that the invention provides a kind of new resistive touch screen is pushed information processing method, this method is divided into A, B, four zones of C, D with this touch-screen, giant-screen is divided into the small screen, then to the position adjustment that independently becomes more meticulous of each the small screen.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be:
A kind of touch screen of resistive touch screen is pushed information processing method, and it may further comprise the steps:
A. wait for extraneous touch input;
B. judged whether touch-control;
C. if any touch-control, obtain by hardware circuit A/D conversion and to push coordinate information;
D. coordinate position is readjusted;
E. stored position information subtracts 1 with the sampling number that presets simultaneously;
F. judge whether sampling number is 0,
As not being 0, continue the C step, as be 0, enter the G step;
G. all positional informations of storage are carried out digital filtering, what obtain expecting pushes coordinate information;
H. the coordinate information of pushing that will expect outputs to main frame,
Its touch-screen is divided into M zone (M is more than or equal to 2), then to the position adjustment that independently becomes more meticulous of each zone.
Equaling 4 with M is example, and its touch-screen is that the boundary is divided into A, B, four zones of C, D with vertical center line and horizontal center line, then to the position adjustment that independently becomes more meticulous of each zone.Location regulation method in the described D step is, sets up the XY two-dimensional coordinate system earlier,
