Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all of the contents related to the present invention.

FIG. 1 is a flowchart of a method for restoring the state of the touch screen before electrostatic reset provided by an embodiment of the present invention. This embodiment is applicable to the case where the state of the touch screen before the electrostatic reset is restored after the electrostatic reset of the touch screen. It is executed by the device for resetting the state of the touch screen before resetting. The device can be implemented by software and/or hardware, and the device can be configured in a mobile terminal with a touch screen such as a mobile phone or a tablet computer. The method specifically includes the following steps:

Step 110, when it is detected that the static state of the touch screen is abnormal, save the touch information of the touch screen.

Wherein, the touch screen touch information preferably includes: the abscissa of the touch point, the ordinate of the touch point, and the state of whether the finger is lifted. In addition, the touch screen touch information may also include a touch pressure value, a contact area between the finger and the touch screen, and the like.

The abnormal static state of the touch screen can easily lead to problems such as black screen or blurred screen of the touch screen. In order to avoid these problems, the static electricity of the touch screen can be eliminated by electrostatic reset. When it is detected that the static state of the touch screen is abnormal, save the touch screen touch information such as the coordinates of the current touch point and whether the finger is lifted. For example, if the user detects that the static state of the touch screen is abnormal during the process of sending voice Touch information, that is, save the state that the finger is not lifted, and then the unfinished voice will not be sent out.

Step 120, performing electrostatic reset on the touch screen.

The electrostatic reset processing of the touch screen in the prior art often requires powering on and off and resetting the touch screen. However, resetting the touch screen will inevitably cause the touch screen to report the action of raising the finger. Interruption of actions such as speech.

In this embodiment, after the touch screen touch information is saved, electrostatic reset processing is performed on the touch screen. Since the touch screen touch information has already recorded whether the finger is lifted, the status of whether the finger is lifted in the touch screen is no longer reported and recorded. Actions that do not conform to the state, that is, the action of raising the finger is no longer reported during the WeChat voice process, so that the WeChat voice and other action processes will not be interrupted. Performing electrostatic reset processing on the touch screen does not affect the functions of other components of the mobile terminal, that is, the touch screen touch information can be stored normally.

Performing electrostatic reset processing on the touch screen, that is, resetting the display system of the touch screen, for example, firstly controlling the LCD (Liquid Crystal Display, liquid crystal display screen) and MIPI (Mobile IndustryProcessor Interface, mobile industry processor interface) of the display module in the touch screen The controller and the MDP (Mobile Display Process, Mobile Display Process) controller are turned off in sequence, and then the MDP controller, MIPI controller and LCD display screen of the display module are controlled to be turned on in sequence. Among them, MIPI is an open standard and a specification for mobile application processors initiated by the MIPI Alliance. The mobile terminal sends the display content to the LCD for display, and the display content needs to be converted into MIPI signals through the MIPI controller; MDP is the chip in the The display processing sub-module is used to send the buffered display content to the display interface; the LCD is used to display the display content to be displayed.

Step 130 , when it is detected that the electrostatic reset is completed, restore the touch screen state before the electrostatic reset according to the touch screen touch information.

Since the process of electrostatic reset is very short, users generally cannot perceive it, so after the electrostatic reset, the user's fingers cannot leave the position before the electrostatic reset. The displayed state can solve the problem of application process interruption caused by electrostatic reset. At the same time, the current touch state of the touch screen is basically the same as that before the electrostatic reset, which will not cause information errors on the touch screen. For example, FIG. 2 is an example diagram of a user using WeChat voice in the method for restoring the touch screen state before electrostatic reset provided by an embodiment of the present invention. As shown in FIG. 2 , the user is using software such as WeChat to make a voice, and the user keeps pressing the touch screen Voice area 1, if the static reset of the touch screen is performed during the process of sending voice, the touch screen touch information will be saved before the static reset. To send voice, after the static reset, because the user's finger is still pressing the recording button, the touch state at this time is similar to the state before the static reset, and the touch screen touch information before the static reset is directly used to replace the current state. Touch the information, then the user's voice will not be interrupted, and the entire voice will not be sent until the user lifts his finger.

Among them, the detection of abnormal static state of the touch screen can optionally include:

When it is detected that the state of the preset register is abnormal, it is determined that the static state of the touch screen is abnormal.

When judging whether the current touch screen has abnormal static state, the state of the preset register can be read. If the state is abnormal, it means that the touch screen has abnormal static state, wherein the preset register is a register related to the static state of the touch screen. By judging the static state of the touch screen by reading the state of the preset register, the static state of the touch screen can be quickly determined.

Among them, the detection of abnormal static state of the touch screen can also optionally include:

When an error occurs in the I2C (Inter-Integrated Circuit, built-in integrated circuit) bus communication process of the touch screen, it is determined that the static state of the touch screen is abnormal.

To detect the static state of the current touch screen, it can also be judged by detecting whether the I2C bus communication process is normal. If there is an error in the I2C bus communication process, that is, the I2C reading fails, it means that the touch screen has abnormal static state. Among them, the I2C bus is a two-wire serial bus developed by PHILIPS, which is used to connect microcontrollers and their peripheral devices. It is a bus standard widely used in the field of microelectronic communication control. It is a special kind of synchronous communication. It has the advantages of less interface lines, simple control method, small device package form, and high communication rate.

In the technical solution of this embodiment, when an abnormal static state of the touch screen is detected, the touch screen touch information is saved, and after the electrostatic reset is completed, the touch screen state before the electrostatic reset is restored according to the touch screen touch information, thereby solving the problem caused by the static reset. The application process is interrupted.

The touch screen touch information restores the touch screen state before the electrostatic reset" is further optimized to "when the completion of the electrostatic reset is detected, receive the current touch information reported by the touch screen; replace the current touch information with the touch screen touch information ". The method specifically includes the following steps:

Step 310, when it is detected that the static state of the touch screen is abnormal, save the touch information of the touch screen.

Step 320, performing electrostatic reset on the touch screen.

Step 330: When it is detected that the electrostatic reset is completed, the current touch information reported by the touch screen is received.

After obtaining the current touch information, that is, the touch information of the first touch point, it will be reported, and the processor of the mobile terminal will receive it. Current touch information reported by the touch screen.

Step 340: Replace the current touch information with the touch screen touch information.

After the electrostatic reset of the touch screen is completed, after receiving the current touch information reported by the touch screen, that is, the touch information of the first touch point, the touch screen touch information before the electrostatic reset is used to replace the current touch information, so that the state of the touch screen is restored to The state before electrostatic reset.
