Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
As shown in Figure 1, present embodiment provides a kind of implementation method of touch key-press learning correction, it is characterized in that, may further comprise the steps:
Step S001: under correcting state,, and ask the mean value of this N time touch sensible data through the touch sensible data of N senses touch key circuit;
Step S002: through a self-defined title this mean value is stored, selected as a threshold value through the user, whether effective to judge the touch sensible data under the user mode, wherein N is the natural number greater than 2.
Preferable, comprised also that before said step S001 state selects, i.e. the selection of correcting state and user mode, if correcting state execution in step S001 then, if whether the then said system of user mode is effective according to said threshold decision touch sensible data.Method of the present invention goes for the various equipment that have liquid crystal touch screen, can carry out touch sensible study to different user, and learning value is stored, and touches correction so that different users calls the value of oneself, has improved the sensitivity that touches.
Below we to be applied on a LCD TV or the display with this method be that example describes; As shown in Figure 2; This LCD TV or display comprise a PSoC (Programmable System-On-Chip; Programmable system on the sheet) single chip module, this PSoC single chip module is accomplished said step S001 after receiving the correction instruction of this LCD TV MCU.See also Fig. 3; This PSoC single chip module (empty frame part among Fig. 3) adopts a comparator to detect the change in voltage that is recharged electric capacity, and the output Fosc of comparator is as the triggering input of PWM, in the preset measurement period of PWM (for example calculating 10 Fosc cycles); Keep being output as high level; As the enable signal of TIMER, promptly with the gate time width of PWM output, simultaneously with the input signal of fixing system clock as TIMER as TIMER.TIMER cycle statistics to system clock in the time width that PWM enables to allow is output n (count), so data n has been represented the size of current inductance capacitance indirectly.And when finger touch, along with Cp becomes big, Fosc and n value be respective change all.Under the situation of same charging current, when finger touch was arranged, it is big that inductance capacitance Cp becomes, and to the inductance capacitance charging and to cause its voltage to be elevated to time of assign thresholds elongated, promptly the cycle of Fosc is elongated.So in the preset statistics of same PWM number, the time width that PWM keeps being output as high level will become greatly, promptly the gate time scope of TIMER will become big.So counting n, can increase the detected system clock cycle of TIMER.Please continue referring to Fig. 4 initial sensed data 1: the counting n1 of detected Timer when not having finger touch; Touch sensible data 2: the counting n2 of detected Timer when finger touch is arranged; Wherein 3 is frequency of oscillation, and 4 is pwm signal, and 5 is clock signal; Then from figure, can know the button threshold value: establishing the difference that the touch sensible data deduct initial sensed data is ⊿ n, ⊿ n=n2-n1; ， ⊿ n=16 Zhong last figure.If the user does not open calibration function and non-selected historical user's best button threshold values, the threshold values of threshold registers is the acquiescence button Fa Zhi ⊿ n that sends over of MCU (Jia Ding Wei ⊿ n=16).Press as button; The PSoC single chip module deducts detected touch sensible data n 2 according to detected initial sensed data n1; Calculate current calculating touch Zhi Wei ⊿ k=n2 – n1, software can be judged when ⊿ k Da Yu ⊿ n, thinks effective touch key-press action; When ⊿ k Xiao Yu ⊿ n, think invalid touch key-press action, judge that detected data are to be caused by noise; If the user selects calibration function, the threshold values of threshold registers is the minimum button Yu Zhi ⊿ m that MCU sends over,
After the user pressed x button, the PSoC single chip module obtained the reference count n2 [x] when x time actuation of keys being arranged, and calculates each touch value: ⊿ h [x]=n2 [x] – n1 respectively.Software can be got the Ping Jun Zhi ⊿ h of x touch value as the button threshold values, writes threshold registers, sends MCU record and preservation through I2C simultaneously, proofreaies and correct and accomplishes.This moment, the threshold registers value was best button threshold values.Here be noted that when preserving the user can store by the laggard row of self-defined title, for example,, when then Zhang San uses later on, directly transfer Zhang San and get final product through menu with the optimal threshold called after " Zhang San " of oneself.
Concrete, seeing also Fig. 5, Fig. 5 is the system works flow process sketch map that is applied to LCD TV or display, its step roughly comprises:
1), MCU menu control correction module provides the user to select the best button threshold values of calibration function or historical record.
2), MCU sends corrective command through I2C and gives PSoC single-chip software and hardware combining processing module.
3), MCU judges whether to open calibration function; If do not open calibration function and do not use historical user record; MCU sends acquiescence button Fa Zhi ⊿ n and gives the PsoC threshold registers; PosC senses touch sensed data n2 calculates touch value (signal difference of touch sensible data and initial sensed data): ⊿ k=n2 – n1 (n1 is initial sensed data), reads the button threshold values in the threshold registers.Do comparison with touch Zhi ⊿ k and button Fa Zhi ⊿ n, touch effectively if touch Zhi ⊿ k greater than button Fa Zhi ⊿ n, is judged to be, send effective order through I2C and give MCU, MCU handles actuation of keys; If touch Zhi ⊿ k is less than button Fa Zhi ⊿ n, being judged to be is noise, does not process.
4) if the user opens calibration function; MCU sends minimum button Yu Zhi ⊿ m and gives the Psoc threshold registers; PSoC single-chip software and hardware combining processing module is obtained the reference count n2 [x] when x time actuation of keys being arranged, and calculates each touch value: ⊿ h [x]=n2 [x] – n1 respectively.The Ping Jun Zhi ⊿ h that gets x touch value writes threshold registers as the button threshold values, sends MCU record and preservation through I2C simultaneously, proofreaies and correct and accomplishes.This moment, the threshold registers value was best button threshold values.
5) if the user uses historical record; MCU sends best button threshold values and gives the PsoC threshold registers; PosC senses touch sensed data n2; Calculate touch value (signal difference of touch sensible data and initial sensed data): ⊿ k=n2 – n1 (n1 is the initial perception data), read the button threshold values in the threshold registers.Do comparison with touch Zhi ⊿ k and button Fa Zhi ⊿ n, touch effectively if touch Zhi ⊿ k greater than button Fa Zhi ⊿ n, is judged to be, send effective order through IC and give MCU, MCU handles actuation of keys; If touch Zhi ⊿ k is less than button Fa Zhi ⊿ n, being judged to be is noise, does not process.
