The entire contents are incorporated by reference in this application.

technical field

The present application relates to the field of intelligent push technology, and in particular to a stylus optimization method, system, mobile terminal and computer-readable storage medium.

Background technique

With the explosive growth of smartphones and tablets, more and more applications require highly sensitive touch; such as painting software, the application of stylus is gradually widespread, and the performance requirements of stylus are getting higher and higher. However, finger operation has limitations, because thick fingers make it difficult to write accurately on a small screen, so a variety of stylus has been produced, and the currently widely used ones are represented by passive capacitive stylus and Apple iPad. active pen.

The capacitive pen is a pen made of conductive materials with conductive properties, which is used to touch the capacitive screen to complete the man-machine dialogue operation. The capacitive pen is an auxiliary device that uses conductive materials to imitate the human body (usually fingers) to complete man-machine dialogue. The capacitive touch screen works by using the current induction of the human body. It is a four-layer composite glass screen. The inner surface and interlayer of the glass screen are each coated with a layer of ITO (that is, coated conductive glass), and the outermost layer is a thin layer of silicon. Earth glass protective layer. The ITO coating is used as the working surface, four electrodes are drawn from the four corners, and the inner layer of ITO is the shielding layer to ensure a good working environment. When the finger touches the metal layer, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitance, for high-frequency current, the capacitance is a direct conductor, so the finger absorbs a very small current from the contact point. This current flows out of the electrodes on the four corners of the touch screen respectively, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller obtains the touch point by accurately calculating the four current ratios. location information.

The capacitive passive pen can be used as a small finger. Generally, the diameter of the pen head is about 2~3mm. The pen itself does not emit signals, but it can change the capacitance of the touch screen matrix when it is in contact with the touch screen. Usually, the passive pen head is relatively large to have sufficient sensitivity. When the pen head is small, the amount of touch changes caused by the pen is small, and the signal-to-noise ratio is insufficient, resulting in insensitive touch operations such as scribing and clicking.

technical problem

In order to take into account the effect of the passive capacitive pen, the current touch software needs to be debugged more sensitively. When there is a strong interference signal, it is easy to produce abnormalities such as automatic false touch.

Embodiment of this application

In order to make the purpose, technical solution and advantages of the present application more clear and definite, the present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

A stylus (Stylus or stylus pen) is a small pen-shaped tool used to input commands to devices with touch screens such as computer screens, mobile devices, and graphics tablets. Users can click on the touch screen with the stylus to select files. or painting. The stylus will bring great convenience to people when playing games and office work, because now the birth of the stylus in the market, there will be more and more touch games, because playing touch If you don’t use a pen to play the game, but use the mouse to use it, it will not be fun, and it will have many small functions, such as the ability to easily zoom the screen and so on. In addition, the new version of the computer system will have a lot of touch functions, which will be more conducive to people's operations. This stylus will have a marking function during office work. For example, when you play a ppt, we It can use its fluorescence effect to make easy-to-remember marks during ppt analysis. Here are some functional applications of the stylus.

The capacitive pen is mainly made of conductive materials with conductive properties. It is used to complete the man-machine dialogue operation on the touch capacitive screen. It is an auxiliary device that uses the conductor material to imitate the human body (usually fingers) to complete the man-machine dialogue. ; Capacitive pens are divided into active and passive. Passive capacitive pens are similar to fingers, and can change the coupling capacitance mentioned above. The active capacitive pen is used as the emitter (so it needs a power supply), and the capacitive screen detects the active capacitive pen to turn off its own emitter. The active and passive detection modes are different, and the two modes do not exist at the same time. Common mobile phone capacitive screens only support passive capacitive pens. The difference between the capacitive pen and the stylus is the difference in the conductor material, mechanism of action and applicable objects. The tip of the capacitive pen has static electricity, and the capacitive screen itself has the technical characteristics of inducting static electricity, so the capacitive pen is suitable for capacitive screens; The stylus works by pressing the screen and is suitable for resistive screens.

The capacitive passive pen can be used as a small finger. Generally, the diameter of the pen head is about 2~3mm. The pen itself does not emit signals, but it can change the capacitance of the touch screen matrix when it is in contact with the touch screen. Usually, the passive pen head is relatively large to have sufficient sensitivity. When the pen head is small, the amount of touch changes caused by the pen is small, and the signal-to-noise ratio is insufficient, resulting in insensitive touch operations such as scribing and clicking. In order to take into account the effect of the passive capacitive pen, the current touch software needs to be debugged more sensitively. When there is a strong interference signal, it is easy to produce abnormalities such as automatic false touch. Because the passive pen itself is not a source of signal emission, the contact accuracy of the pen tip is low and there is no pressure induction. It is impossible to change the thickness of handwriting through changes in writing force, and it is difficult to meet high-precision requirements such as painting.

In view of the above-mentioned defects of the prior art, the stylus optimization method described in the preferred embodiment of the present application, as shown in Figure 1, the stylus optimization method includes the following steps:

Step S10, pre-adding a stylus recognition mode to the system of the mobile terminal.

Adding the stylus recognition mode in advance in the mobile terminal system includes: adding the stylus recognition mode through the desktop UI and adding the stylus recognition mode through system settings.

As shown in Figure 2, the Stylus (stylus) recognition mode is added to the UI desktop, where Stylus represents the added recognition mode of the stylus, as shown in Figure 3, add the stylus option (including touch pen) pen control scene, mode),

You can enter the stylus mode adjustment interface by setting the Stylus (pen mode) APP through the desktop UI or the stylus in the system settings (as shown in Figure 4), that is, enter the stylus recognition mode adjustment The way of the interface includes: setting the pen mode APP or the stylus in the system setting through the desktop UI; the operation mode of the stylus includes: the stylus mode, the adaptive mode and the finger operation mode, and the user can select the finger touch mode , pen and hand simultaneous operation mode and writing pen three modes. According to different usage scenarios, the touch IC terminal adapts different algorithms and parameters to meet user needs, that is, selects the corresponding operation mode of the stylus according to different usage scenarios.

As shown in Figure 4, the stylus mode is used to provide a smooth writing experience. When the stylus is not in use, it is recommended to turn it off to reduce the risk of false touches; the adaptive mode supports simultaneous operation of fingers and pens. The fluency is moderate; the finger operation mode supports finger touch operation, and the performance of pen operation is not good.

Step S20, when entering the scene of the stylus recognition mode, the system of the mobile terminal sends a control command to the touch IC.

Specifically, when the mobile terminal enters the stylus recognition mode scene, the mobile terminal system notifies the touch IC, that is, sends a control command to the touch IC.

Among them, touch here specifically refers to single-point or multi-point touch technology. IC is an integrated circuit, which is a general term for semiconductor component products; touch IC solves the problem of easy accumulation of dust in the traditional key groove, and at the same time increases the control key. The service life is a major breakthrough in button control; touch ICs usually support a wide operating voltage range, and integrate a high-resolution touch detection module and a dedicated signal processing circuit to ensure that the IC has a sensitive automatic identification and tracking function for environmental changes, and Built-in special algorithms to meet waterproof, anti-jamming and other requirements. The most advanced touch chips in China include XC2862 series ICs, etc., which can meet users' high requirements for stability, sensitivity, power consumption, response speed, waterproof, operation with water, anti-vibration, and anti-electromagnetic interference in complex applications. Experience requirements, and with combined functions such as proximity detection and multi-level sensitivity adjustment.

Integrated circuits use semiconductor manufacturing technology to manufacture many transistors, resistors, capacitors and other components on a small single crystal silicon chip, and combine the components into a complete electronic circuit according to the method of multi-layer wiring or tunnel wiring. circuit. It is represented by the letter "IC" (also with the text symbol "N", etc.) in the circuit. IC is a general term for semiconductor component products. In a broad sense, it also involves all electronic components, such as resistors, capacitors, circuit boards/PCB boards, and many other related products.

Step S30 , the touch IC is adapted through an analog front-end circuit module to obtain an optimal signal-to-noise ratio setting value.

Specifically, the touch IC AFE (Analog Front End analog front-end circuit module) front-end module circuit is specially adapted to find the best signal-to-noise ratio (SNR) setting value, and the passive pen can obtain enough touch signal changes by optimizing the software algorithm. volume, improve the effect of passive pen writing. In this application, after entering the passive pen recognition mode, the touch IC switches the front-end AFE circuit parameters, and then finds the best SNR through the pen mode software algorithm processing, effectively solving the problem of insufficient change of the passive pen signal.

Among them, the signal-to-noise ratio (SNR, SIGNAL-NOISE RATIO) refers to the ratio of signal to noise in an electronic device or electronic system. The signal here refers to the electronic signal from the outside of the device that needs to be processed by this device, and the noise refers to the irregular extra signal (or information) that does not exist in the original signal after passing through the device, and this kind The signal does not change with the original signal. Similarly, "the original signal does not exist" and there is another thing called "distortion". In fact, distortion and noise are related to a certain extent. The difference between the two is that distortion is regular, while noise is irregular. The measurement unit of the signal-to-noise ratio is dB, and its calculation method is 10lg (Ps/Pn), where Ps and Pn represent the effective power of the signal and noise respectively, and can also be converted into the ratio relationship of the voltage amplitude: 20Lg (Vs/Vn) , Vs and Vn represent the "rms" of the signal and noise voltages, respectively. In an audio amplifier, what we hope is that the amplifier should not add any other extra things besides amplifying the signal. Therefore, the signal-to-noise ratio should be as high as possible. In a narrow sense, it refers to the ratio of the power of the output signal of the amplifier to the noise power output at the same time, often expressed in decibels. The higher the signal-to-noise ratio of the device, the less noise it generates. Generally speaking, the larger the signal-to-noise ratio, the smaller the noise mixed in the signal, and the higher the sound quality of the sound playback, otherwise the opposite is true. The signal-to-noise ratio should generally not be lower than 70dB, and the signal-to-noise ratio of high-fidelity speakers should reach above 110dB.

The signal-to-noise ratio is the difference between the normal sound signal played back by the speaker and the noise signal (power) when there is no signal. Expressed in dB. For example, the signal-to-noise ratio of a speaker is 80dB, that is, the output signal power is 10^8 times the noise power, and the standard deviation of the output signal is 10^4 times the noise standard deviation. The higher the value of the signal-to-noise ratio, the smaller the relative noise . The broad definition of "noise" is: "signals generated by the device itself during processing" that are not related to the input signal. For MP3 players, the signal-to-noise ratio is a relatively important parameter. It refers to the ratio between the maximum undistorted sound signal intensity produced by the audio source and the simultaneous noise intensity. It is called the signal-to-noise ratio, or SNR for short (Signal/ Noise), usually expressed in S/N, in decibels (dB). For the player, the larger the value, the better. At present, the signal-to-noise ratio of MP3 players is 60dB, 65dB, 85dB, 90dB, 95dB, etc. When we choose MP3, we generally choose 60dB or more, but even if this parameter meets the requirements, it does not necessarily mean that the machine is good. , after all, it is only one of the parameters to be considered in the MP3 performance parameters. Refers to the ratio of the output signal voltage under the specified input voltage to the residual noise voltage output when the input voltage is cut off. It can also be regarded as the ratio between the maximum undistorted sound signal strength and the noise strength emitted at the same time, usually in S /N means. Generally, decibels (dB) are used as the unit. The higher the signal-to-noise ratio, the better the audio product. Common products are above 60dB.

The signal-to-noise ratio is a main technical index to measure the reliability of the communication quality of the communication system. According to different needs in communication, there are different ways of expression. In the transmission of modulated signals, the signal-to-noise ratio generally refers to the ratio of the average power of the carrier signal at the input of the receiver to the average power of the noise in the channel at the output of the channel, which can be called the carrier-to-noise ratio. In an analog communication system, the signal-to-noise ratio generally refers to the ratio of the average power of the signal at the output of the demodulator of the communication terminal to the average power of the noise. In engineering, a set of curves between the input signal-to-noise ratio and the output signal-to-noise ratio of the demodulator is also used to quantitatively compare the communication quality of different analog modulation and demodulation methods. For example: when the input signal-to-noise ratio of the demodulator is the same, the output signal-to-noise ratio is better than FM than AM, and synchronous detection is better than envelope detection. In a digital communication system, the signal-to-noise ratio generally refers to the ratio E/N0 of the average signal energy E of each digital waveform (bit) at the output end of the digital demodulator or decoder of the terminal to the noise power N0 in the unit frequency band , also known as normalized signal-to-noise ratio or energy signal-to-noise ratio, is a commonly used indicator. A set of curves between E/N0 and error (bit error) probability Pe can also be used to represent different digital modulation and demodulation, or the communication quality of different types of channel encoding and decoding. For example, in the demodulator output When the end has the same quality requirements (same error rate), the requirement for signal-to-noise ratio is lower (good) than frequency shifting, frequency shifting is lower than amplitude shifting, and coherent detection is lower than non-coherent detection. Low not used. Therefore, selecting the best modem is the main means to improve the signal-to-noise ratio of the communication system. Increasing or improving the signal-to-noise ratio is a major task to improve the quality of communication. In transmission, it is possible to improve the transmission means and It can be achieved by increasing equipment capabilities. For example, optical cables, coaxial cables or satellite channels are used to reduce transmission loss and noise. However, after the channel is selected, it is mainly by increasing equipment capabilities, such as increasing antenna gain and reducing receivers in satellite communications. The effective noise temperature. Information theory points out: For the time-limited, white Gaussian noise channel with the common bandwidth of F, the channel capacity. When the capacity is constant, increasing the bandwidth can reduce the SNR, and the bandwidth must be compressed to improve the SNR. Therefore, the anti- When interference is the main contradiction, the frequency band can be extended for reception under low SNR. Both FM and spread spectrum are based on this principle. When frequency band is the main contradiction, SNR can be used for frequency band. Based on this principle.

This application adds a stylus recognition mode to the mobile terminal (such as a mobile phone) system. When entering the pen mode scene, the mobile terminal system notifies the touch IC, and the touch IC AFE front-end module circuit is specially adapted to find the best signal-to-noise Ratio (SNR) setting value, by optimizing the software algorithm, the passive pen can obtain enough touch signal change to improve the writing effect of the passive pen. In this application, after entering the passive pen recognition mode, the touch IC switches the front-end AFE circuit parameters, and then finds the best SNR through the pen mode software algorithm processing, effectively solving the problem of insufficient change of the passive pen signal.
