Abstract
The embodiment of the invention relates to the touch technical field, in particular to a touch screen detection method and a terminal used for reducing the probability of the misoperation of a user. In the embodiment of the invention, a touch device obtains indication information from a distance sensor periodically; if the touch device determines that the distance between an obstacle and the touch screen is smaller than a first threshold value according to the information, then the touch operation is not processed during the period from the current time to that the indication information is obtained from the distance sensor next time. Since a mobile phone is in an abnormal working state when the distance between the obstacle and the touch screen is smaller than the first threshold value, the touch operation during the period from the current time to that the indication information is obtained from the distance sensor next time is the misoperation caused by the collision and hit of the obstacle, thus, when the distance between the obstacle and the touch screen is smaller than the first threshold value, during the period from the current time to that the indication information is obtained from the distance sensor next time, the touch device does not process the touch operation during this period. Thereby, the misoperation probability caused by the touch of the obstacle is reduced.

Embodiment
In order to make object of the present invention, technical scheme and beneficial effect better clear, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 illustrates the system architecture that the embodiment of the present invention uses.
The method that the embodiment of the present invention provides is applicable to the terminal being provided with touch-screen 101, touch controller 102 and range sensor 103, and this terminal can be mobile phone terminal, tablet terminal etc.As shown in Figure 1, this terminal also comprises central processing unit (Central Processing Unit, be called for short: CPU) 104, range sensor 103 and CPU104 are by serial data (Serial Data, be called for short SDA) pin, serial clock (SerialClock, be called for short SCL) pin, interrupt pin (Interrupt, be called for short INT) connect, CPU104 passes through SDA, SCL, INT pin is connected with touch controller 102, the INT pin of range sensor 103 and the universal input of touch controller 102 export (General Purpose Input Output, be called for short: GPIO) pin connects.
The application scenarios of the embodiment of the present invention is, after above-mentioned terminal is set to standby dormant state by user, CPU receives deep sleep state instruction, starts to prepare penetration depth dormancy, notifies that the equipment such as range sensor, touch controller enters low-power consumption duty before penetration depth dormant state.Range sensor receives the information entering low-power consumption duty, then enter low-power consumption duty according to the information entering low-power consumption duty.Touch controller receives the information entering low-power consumption duty, then enter low-power consumption duty according to the information entering low-power consumption duty.Some other equipment also enters low-power consumption duty, afterwards, and the complete penetration depth dormant state of CPU.
After range sensor enters low-power consumption duty, and the distance between periodic scan barrier and touch-screen, and the look-at-me of output low level when being less than first threshold of the distance between barrier and touch-screen, export the look-at-me of high level when the distance between barrier and touch-screen is not less than first threshold.CPU is in deep-sleep, not to the response for changing of this level.
After touch controller enters low-power consumption duty, the indication information of the distance periodically from range sensor between acquisition instruction barrier and touch-screen and the relation of first threshold.This cycle can be set to a few tens of milliseconds to hundreds of millisecond.Touch controller starts GPIO pin, and when obtaining the indication information of the relation of distance between instruction barrier and touch-screen and first threshold from range sensor, power consumption added value is less than 1mA.The cycle length that touch controller reads indication information from range sensor is longer, then power consumption is less, otherwise then power consumption is larger.
When touch controller reads high level, think that the distance between barrier and touch-screen is not less than first threshold, now touch controller thinks that mobile phone is in normal operating conditions, self is set to low-power consumption duty.Under low-power consumption duty, touch controller can detect contact action, and can identify this contact action, can carry out next step process after identification to this gesture operation, such as, wakes CPU up and by this information reporting to CPU.
When touch controller reads low level, think that the distance between barrier and touch-screen is less than first threshold, now, terminal may be placed in pocket or in knapsack, and it may be maloperation because the scraping of barrier causes that contact action now occurs.Now the state of self is set to the duty of super low-power consumption by touch controller.Under super low-power consumption duty, touch controller only can detect contact action, when not identifying the meaning of this contact action, because touch controller can not identify the meaning of this contact action, therefore also can not carry out next step process to this contact action.Thus alleviate the equipment power dissipation that the touch screen due to barrier causes, extend the device standby time further.
Preferably, the touch controller in the embodiment of the present invention can be touch controller machine, and can adopt the GT970 converging and push up, the GPIO pin on touch controller can be chosen to be the OPT1 pin of this chip.The ePL2182 that range sensor can select justice grand.
Fig. 2 illustrates a kind of detection method of touch screen that the embodiment of the present invention provides.
Based on said system framework, the method that the embodiment of the present invention provides is applicable to the terminal being provided with touch-screen, touch controller and range sensor, and this terminal can be mobile phone terminal, PC terminal, tablet terminal etc.As shown in Figure 2, comprise the following steps:
Step 201, touch controller periodically obtains indication information from range sensor; Indication information is used to indicate the relation of distance between barrier and touch-screen and first threshold;
Step 202, if described touch controller is less than first threshold according to the distance between described indication information determination barrier and touch-screen, then, during obtaining indication information from current time to next time from range sensor, does not process contact action.
In the embodiment of the present invention, due to the distance between barrier and touch-screen be less than first threshold time, mobile phone is in abnormal operating state, from current time to next time from the maloperation that the range sensor contact action obtained during indication information is because barrier percussion causes, therefore, when distance between barrier and touch-screen is less than first threshold, during obtaining indication information from current time to next time from range sensor, contact action during touch controller does not process this.Thus alleviate the misoperation probability that the touch screen due to barrier causes.
Preferably, if touch controller is less than first threshold according to the distance between indication information determination barrier and touch-screen, then, during obtaining indication information from current time to next time from range sensor, enter super low-power consumption duty; Under super low consumption duty, then do not process contact action.
Preferably, under super low consumption duty, if touch controller detects, and touch-screen has contact action, then do not process contact action.
Before above-mentioned steps 201, specifically, after above-mentioned terminal is set to standby dormant state by user, CPU receives deep sleep state instruction, start to prepare penetration depth dormancy, before penetration depth dormant state, notify that the equipment such as range sensor, touch controller enters low-power consumption duty.Range sensor receives the information entering low-power consumption duty, then enter low-power consumption duty according to the information entering low-power consumption duty.Touch controller receives the information entering low-power consumption duty, then enter low-power consumption duty according to the information entering low-power consumption duty.Some other equipment also enters low-power consumption duty, afterwards, and the complete penetration depth dormant state of CPU.
After range sensor enters low-power consumption duty, and the distance between periodic scan barrier and touch-screen, and the look-at-me of output low level when being less than first threshold of the distance between barrier and touch-screen, export the look-at-me of high level when the distance between barrier and touch-screen is not less than first threshold.CPU is in deep-sleep, not to the response for changing of this level.
After touch controller enters low-power consumption duty, the indication information of the distance periodically from range sensor between acquisition instruction barrier and touch-screen and the relation of first threshold.This cycle can be set to a few tens of milliseconds to hundreds of millisecond.Touch controller starts GPIO pin, and when obtaining the indication information of the relation of distance between instruction barrier and touch-screen and first threshold from range sensor, power consumption added value is less than 1mA.The cycle length that touch controller reads indication information from range sensor is longer, then power consumption is less, otherwise then power consumption is larger.
Accordingly, touch controller periodically reads the look-at-me that range sensor exports, look-at-me represents when being low level that the distance between barrier and touch-screen is less than first threshold, represents that the distance between barrier and touch-screen is not less than first threshold when look-at-me is high level.
Preferably, if touch controller is not less than first threshold according to the distance between indication information determination barrier and touch-screen, if during obtaining indication information from current time to next time from range sensor, touch controller detects, and touch-screen has contact action, then process contact action.
Or there is another kind preferably implementation, if touch controller is not less than first threshold according to the distance between indication information determination barrier and touch-screen, then enter low-power consumption duty; Under low consumption duty, if touch controller detects, and touch-screen has contact action, then process contact action.
When touch controller reads high level, think that the distance between barrier and touch-screen is not less than first threshold, now touch controller thinks that mobile phone is in normal operating conditions, self is set to low-power consumption duty.Under low-power consumption duty, touch controller can detect contact action, and can identify this contact action, can carry out next step process after identification to this gesture operation, such as, wakes CPU up and by this information reporting to CPU.Therefore, under low consumption duty, if touch controller detects, and touch-screen has contact action, then process contact action.
When touch controller reads low level, think that the distance between barrier and touch-screen is less than first threshold, now, terminal may be placed in pocket or in knapsack, and it may be maloperation because the scraping of barrier causes that contact action now occurs.Now the state of self is set to the duty of super low-power consumption by touch controller.Under super low-power consumption duty, touch controller only can detect contact action, when not identifying the meaning of this contact action, because touch controller can not identify the meaning of this contact action, therefore also can not carry out next step process to this contact action.Thus alleviate the equipment power dissipation that the touch screen due to barrier causes, extend the device standby time further.
In the embodiment of the present invention, touch controller periodically obtains indication information from range sensor; If touch controller is less than first threshold according to the distance between indication information determination barrier and touch-screen, then, during obtaining indication information from current time to next time from range sensor, do not process contact action.Due to the distance between barrier and touch-screen be less than first threshold time, mobile phone is in abnormal operating state, from current time to next time from the maloperation that the range sensor contact action obtained during indication information is because barrier percussion causes, therefore, when distance between barrier and touch-screen is less than first threshold, during obtaining indication information from current time to next time from range sensor, contact action during touch controller does not process this.Thus alleviate the misoperation probability that the touch screen due to barrier causes, and reduce further power consumption, extend the device standby time.
