Embodiment
For make purpose of the present invention, technical scheme, and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.Obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The schematic flow sheet of the calibration steps of embodiment of the invention touch display screen coordinate as shown in Figure 2, this calibration steps may further comprise the steps:
The present invention is an example with three input sample districts, and each input sample district comprises 4 touch display screen physical points.For the touch display screen terminal, according to the distribution of virtual digit keyboard on the terminal, what choose is 1 on the terminal, 3 and 8 virtual digit buttons, lays respectively at the upper left corner, the upper right corner and the centre position of touch display screen.Each user can have a fixing custom when using terminal push, a certain fixed position of the digital keys of promptly feeling the pulse with three fingers simulataneously for example, in contact button 1, may always contact with the left side of digital keys 1.According to common practise, the zone of a digital keys covers a plurality of LCD pixels, the corresponding lcd screen coordinate of LCD pixel, that is to say the same area that always touches a digital keys, will obtain same lcd screen coordinate, and a custom that has user's contact touch display screen when using terminal of this terminal remains unchanged also generally.For example, for the digital keys on the touch display screen terminal 1, this digital keys is divided into four zones, respectively corresponding four touch display screen physical points 1,2,3 and 4, these four touch display screen physical points are four LCD pixels 1 ', 2 ', 3 ' and 4 ' of corresponding lcd screen respectively.The user always contacts the left side according to custom when using terminal contact digital keys 1, promptly trigger touch display screen physical points 1, and touch display screen physical points 1 pairing touch display screen coordinate conversion is LCD pixel a 1 ' pairing lcd screen coordinate.From statistics, the statistical law that triggering LCD pixel is showed roughly is two-dimentional normal distribution, as shown in Figure 3.The maximal value of Z axle represents that the coordinate points of density maximum is called lcd screen coordinate extreme value through repeatedly button triggering among Fig. 3.From the foregoing description, the coordinate points that LCD pixel 1 ' pairing this lcd screen coordinate on the digital keys 1 is exactly the density maximum, for instance, if the user clicks digital keys 1 totally 100 times, then all can drop on for 90 times near the Δ scope of this density maximum coordinates point, have only and drop on for 10 times near this coordinate points outside the Δ scope, the scope of Δ is very little, drop on the same coordinate as long as drop on all thinking in this Δ scope, so think that through statistics the coordinate points position of being dropped on for 90 times all is a lcd screen coordinate extreme value.Obtaining of this lcd screen coordinate extreme value is by equal difference Calculation Method, inequality refer to each number in one group of data and these group data average difference square and again divided by the number of data.User's point at 100 times hits, LCD pixel 1 ' on the digital keys 1 has and receives triggering command 90 times, other LCD pixels have 10 times and receive triggering command, and the lcd screen coordinate that calculates by equal difference is LCD pixel 1 ' pairing lcd screen coordinate certainly.
We give tacit consent to current touch display screen through calibration after terminal is dispatched from the factory, so a period of time after the first use of touch display screen, perhaps in touch display screen a period of time after touching calibration, promptly in default very first time section, the first lcd screen coordinate of user's LCD pixel correspondence of clicking trigger in described input sample district.Be specially: the lcd screen coordinate figure of recording user LCD pixel correspondence of clicking trigger in each input sample district; According to the lcd screen coordinate figure of each input sample district correspondence, find occurrence number is maximum in the input sample district lcd screen coordinate figure the first lcd screen coordinate as this input sample district.Wherein, each input sample district has one first lcd screen coordinate in very first time section; The maximum lcd screen coordinate figure of occurrence number can be the lcd screen coordinate extreme value of determining by aforesaid statistical way in the described input sample district.
A period of time after touch display screen uses the schedule time for the first time, perhaps, a period of time touch display screen uses the schedule time after touching calibration after, promptly in the second default time period, because touch display screen described in the prior art is aging, reasons such as wearing and tearing, even the user is a touch display screen physical points 1 on the numeric keypad 1 as what originally thought contact still, but the pairing lcd screen coordinate of the LCD pixel that in fact obtains, promptly the second lcd screen coordinate and the first lcd screen coordinate are also inequality, at this moment mistake will occur clicking, that is to say that deviation appears in the touch display screen coordinate.At this moment, the second lcd screen coordinate of user's the 2nd LCD pixel correspondence of clicking trigger in described input sample district.Be specially: the lcd screen coordinate figure of recording user LCD pixel correspondence of clicking trigger in each input sample district; According to the lcd screen coordinate figure of each input sample district correspondence, find occurrence number is maximum in the input sample district lcd screen coordinate figure the second lcd screen coordinate as this input sample district.Wherein, each input sample district has one second lcd screen coordinate in second time period.Wherein, the described schedule time is the chronomere more than 0 or 1, chronomere refer to second, divide and hour etc. chronomere commonly used, 0 chronomere referred to for second time period and is right after the situation of very first time section.
Obtain the first lcd screen coordinate and the second lcd screen coordinate, be in order to carry out the comparison of deviation, relatively whether the grid deviation value between a LCD pixel and described the 2nd LCD pixel is equal to, or greater than default grid deviation threshold value, if mean to touch calibration.Described default grid deviation threshold value is the distance between adjacent two LCD pixels; Wherein, the distance between described adjacent two LCD pixels is that the center of a LCD pixel is to the distance between the center of another one LCD pixel.
