Referring to FIG. 3, it illustrates the flow charts of processor awakening method provided by the embodiments of the present application.This method application
In the touch display screen of terminal, this method comprises the following steps (step 301~303).
Step 301, when touch display screen is in the first scanning mode, with the touch of first frequency monitoring touch display screen
Whether parameter value changes.
First scanning mode is also referred to as idle state (low power consumpting state).When touching is not detected in touch display screen in preset duration
When touching parameter value and changing, into the first scanning mode.When touch display screen is in the first scanning mode, swept with first frequency

First frequency can be set by touch display screen or processor, and the embodiment of the present application is not construed as limiting this.
Touching parameter value can determine according to the type of touch display screen.When touch display screen is that Capacitive touch is shown
Screen, then touching parameter value is capacitance；When touch display screen is resistive touch display screen, touch parameter value is resistance value.
In the embodiment of the present application, it is only illustrated so that touch display screen is Capacitive touch display screen as an example, namely touches parameter value
For resistance value.
Step 302, when the touch parameter value for detecting touch display screen changes, the first interrupt signal is generated.
First interrupt signal switches to wake-up states by dormant state for triggering processor.In the embodiment of the present application,
Effective information (such as touch information) is not carried in first interrupt signal.Optionally, step 302 can implement are as follows: will touch
The value for touching the register of touch chip in display screen is assigned a value of preset value, obtains the first interrupt signal, and the first interrupt signal carries
Preset value.
Above-mentioned preset value can be preset by processor or touch display screen, and the embodiment of the present application is not construed as limiting this.
Illustratively.Preset value is Null (sky).Touch display screen usually exists two layers (being set as x layers and y layers), when touch display screen not
When being pressed, y layers of pin is high level, and when touch display screen has been pressed, x layers and y layers are contacted, and y layers due to connecing
Ground switches to low level from high level, generates interrupt signal at this time.In the embodiment of the present application, touch display screen is to touch chip
In register assignment be preset value, such that due to carry above-mentioned preset value in the interrupt signal for touching and generating, so
To the first interrupt signal.
Optionally, when touch display screen monitors that touching parameter value changes, touch display screen can also be switched
Whether change to the second scanning mode, and with the touch parameter value of second frequency monitoring touch display screen.
Second scanning mode is also referred to as active state (full speed operation state).When touch display screen detects in preset duration
When touch parameter value changes, into the second scanning mode.When touch display screen is in the second scanning mode, with second frequency
Whether the touch parameter value of scanning touch display screen changes, and second frequency is usually larger, can exist to avoid touch display screen
There are scan to touch existing terminal response touch behaviour when whether parameter value changes with lower frequency when operational requirements by user
Time larger problem needed for making, duration needed for reducing terminal response touch operation, promotes response efficiency.Second frequency can
To be not construed as limiting by touch display screen or processor setting, the embodiment of the present application to this.Second frequency is greater than first frequency.
Optionally, touch display screen can also interrupt in transmission first and believe when monitoring that touching parameter value changes
Number while, according to the information such as parameter value calculation touch coordinate are touched, so that touch information can be sent to processor in time.
Promote response efficiency.
Step 303, the first interrupt signal is sent to the processor of terminal.
When contacting there are object (such as finger) and touch display screen, touching parameter value can change.It is shown when touching
When screen detects that touching parameter value changes, the first interrupt signal is sent to processor at once, and not waits until to touch display
Shield to send to processor again after calculating touch coordinate and touches interrupt signal (namely the interrupt signal for carrying touch information), with
Processor in a dormant state is waken up in advance, subsequent touch interrupt signal arrive when, eliminate waiting for CPU from
Time needed for dormant state switches to wake-up states, and then improve the efficiency of processor response touch operation.
Optionally, touch display screen is sending the first interrupt signal, and after calculating the touch informations such as touch coordinate, to place
It manages device and sends touch interrupt signal, which carries touch coordinate, touches the touch informations such as duration.Processor is called out
After waking up, above-mentioned touch interrupt signal can be handled in time, and make a response to touch event.
In a specific example, in conjunction with reference Fig. 4, it illustrates the processors shown in the application one embodiment to call out
The flow chart for method of waking up.Touch display screen is in the first scanning mode, scans (also referred to as idle scanning) capacitance with lower frequency
Whether change, when touch display screen is detected from appearance variation, switches to the second scanning mode, (also referred to as with upper frequency
Active scanning) whether scanning capacitance value change, and sends aerial break signal to processor, preprocessor judge whether
In a dormant state, if processor in a dormant state, exits dormant state, and above-mentioned aerial break signal is handled, if processing
Device is not in dormant state, then directly handles above-mentioned dormant state.It should be noted that touch display screen is sending aerial disconnected letter

Shield to send to processor again after calculating touch coordinate and touches interrupt signal (namely the interrupt signal for carrying touch information), with
Processor in a dormant state is waken up in advance, subsequent touch interrupt signal arrive when, eliminate waiting for CPU from
Time needed for dormant state switches to wake-up states, and then improve the efficiency of processor response touch operation.
Referring to FIG. 5, it illustrates the flow chart of processor awakening method provided by the embodiments of the present application, this method application
In the touch display screen of terminal, this method comprises the following steps (step 501~step 505):
Step 501, when touch display screen is in the first scanning mode, with the touch of first frequency monitoring touch display screen
Whether parameter value changes.
Step 502, when the touch parameter value for monitoring touch display screen changes, the touch of touch display screen is detected
Whether parameter value variation amount is greater than first threshold.
Touching parameter value variation amount is the difference touched between parameter value touched before parameter value and variation after variation
Absolute value.First threshold can be set according to actual needs, and the embodiment of the present application is not construed as limiting this.
Due to other than user, when other objects (such as knapsack, pocket) and touch display screen contact, it is also possible to cause
The touch parameter value of touch display screen changes.When different objects and touch display screen contact, caused touch parameter value
Variable quantity is not identical.For example, it is usually larger to touch parameter variation value variable quantity when touch display screen and user's finger contacts；
For another example it is usually smaller to touch parameter value variation amount when the inanimates such as knapsack, pocket and touch display screen contact.
In the embodiment of the present application, touch display screen, can also be further when detecting the presence of touch parameter value variation
Detection touches whether parameter value variation amount is greater than first threshold.When touching parameter value variation amount more than or equal to first threshold,
Then think that touching parameter value variation is caused by user's finger is contacted with touch display screen, touch display screen executes subsequent step at this time
Rapid 503, alternatively, executing subsequent step 504.When touching parameter value variation amount less than first threshold, then it is assumed that touch parameter value
Variation is not caused by user's finger is contacted with touch display screen, and touch display screen does not execute subsequent step at this time, and terminates to flow
Journey.
By the above-mentioned means, part false triggering can be screened out, the case where touch display screen is by false triggering is avoided
Shift to an earlier date wake-up processor down, the process resource of terminal can be saved.
Step 503, whether detection touch display screen is less than to the nearest time interval that processor sends the second interrupt signal
Second threshold.
Second interrupt signal refers to the interrupt signal for carrying touch information, is usually to detect touching by touch display screen
Touch event, and get the corresponding touch data of the touch event it is rear to processor send.
Nearest time interval refer to touch display screen to processor last time send the second interrupt signal timestamp with
Interval between current time stamp.Illustratively, touch display screen to processor last time send the second interrupt signal when
Between stamp for 11 when 59 divide 23 seconds, 59 divide 56 seconds when current time stamp is 11, then nearest time interval is 33 seconds.
Free time length needed for second threshold can switch to dormant state as wake-up states according to processor is practical determining.
Optionally, second threshold that is to say free time length needed for processor switches to dormant state as wake-up states.In other possibility
Implementation in, processor is corresponding with different grades of dormant state, and free time is longer, then dormant state higher grade,
Time needed for waking up the dormant state is longer.At this point, second threshold can be the dormant state corresponding free time of any grade
Duration.If the high-grade corresponding free time length of dormant state can be determined as to the it is expected that terminal consumes the less energy
Two threshold values；If the corresponding free time length of the dormant state of inferior grade can be determined as it is expected that the response speed of terminal is faster
Second threshold.
When the timestamp that touch display screen sends the second interrupt signal to processor last time is closer apart from current time
When, since processor needs to handle second interrupt signal, then processor is in wake-up states certainly at this time, aerial without sending
Break signal carrys out wake-up processor.
In the embodiment of the present application, by comparing nearest time of the touch display screen to processor the second interrupt signal of transmission
The size relation at interval and second threshold, if nearest time interval is less than second threshold, it is determined that processor has been in wake-up
State, touch display screen does not execute the step of sending first terminal signal at this time, and terminates process, if nearest time interval is big
In or equal to second threshold, it is determined that processor is not in wake-up states, and touch display screen executes subsequent step 505 at this time.
By the above-mentioned means, can be to avoid still the first interrupt signal is sent in the case where processor is in wake-up states the case where
Occur, saves the process resource of terminal.
Step 504, the first interrupt signal is generated.
Step 505, the first interrupt signal is sent to the processor of terminal.
In conclusion technical solution provided by the embodiments of the present application, by detect the presence of touch parameter value variation when,
It can also further detect and touch whether parameter value variation amount is greater than first threshold.It is greater than or equal to when touching parameter value variation amount
When first threshold, then it is assumed that touching parameter value variation is to touch display at this time caused by user's finger is contacted with touch display screen
Screen executes subsequent step；When touching parameter value variation amount less than first threshold, then it is assumed that touching parameter value variation is not user
Caused by finger is contacted with touch display screen, touch display screen does not execute subsequent step at this time, and terminates process；It can be by part
False triggering screens out, and avoids touch display screen by wake-up processor in advance in the case where false triggering, can save terminal
Process resource.
Also by comparing nearest time interval and second threshold of the touch display screen to processor the second interrupt signal of transmission
Size relation, if nearest time interval is less than second threshold, it is determined that processor has been in wake-up states, touches at this time aobvious
Display screen does not execute the step of sending first terminal signal, and terminates process, if nearest time interval is greater than or equal to the second threshold
Value, it is determined that processor is not in wake-up states, and touch display screen executes subsequent step at this time；It can be in avoid in processor
Still the case where the first interrupt signal is sent under wake-up states generation, saves the process resource of terminal.

Whether the nearest time interval that device sends the second interrupt signal is less than second threshold.
In the embodiment of the present application, by comparing nearest time of the touch display screen to processor the second interrupt signal of transmission
The size relation at interval and second threshold, if nearest time interval is less than second threshold, it is determined that processor has been in wake-up
State, touch display screen does not execute the step of sending first terminal signal at this time, and terminates process, if nearest time interval is big
In or be equal to second threshold, it is determined that processor is not in wake-up states, at this time touch display screen execute subsequent step 603 or
604。
Step 603, whether the touch parameter value variation amount for detecting touch display screen is greater than first threshold.
In the embodiment of the present application, touch display screen, can also be further when detecting the presence of touch parameter value variation
Detection touches whether parameter value variation amount is greater than first threshold.When touching parameter value variation amount more than or equal to first threshold,
Then think that touching parameter value variation is caused by user's finger is contacted with touch display screen, touch display screen executes subsequent step at this time
