Embodiment 1

[0022] figure 1 It is a flow chart of a touch screen anti-interference method provided by Embodiment 1 of the present invention. This embodiment is applicable to mobile terminals with internal charge pumps, while reducing the touch screen interference caused by using non-standard adapters while ensuring that most cases In the case of the radio frequency performance index, the method can be performed by a mobile terminal with an internal charge pump, and specifically includes the following steps:

[0023] Step 110, turn off the power supply of the internal charge pump.

[0024] Since the power supply of the internal charge pump is always turned on, it will affect the radio frequency performance index of the mobile terminal and affect the call quality, so the power supply of the internal charge pump is turned off by default to ensure the radio frequency performance of the mobile terminal.

[0025] Among them, the charge pump, called switched capacitor voltage converter, is a DC...

Embodiment 2

[0045] figure 2 It is a flowchart of a touch screen anti-interference method provided by Embodiment 2 of the present invention. This embodiment is based on Embodiment 1 and optimizes the operation after turning on the internal charge pump power supply in Embodiment 1. When the When the adapter is pulled out of the USB interface, the power supply of the internal charge pump is turned off, and the specific steps are as follows:

[0046] Step 210, turn off the power supply of the internal charge pump.

[0047] Step 220, detecting whether there is an adapter plugged into the USB interface.

[0048] Step 230, when it is detected that an adapter is plugged into the USB interface, it is judged whether the adapter is a standard adapter.

[0049] Step 240, if the judgment result is yes, keep turning off the power supply of the internal charge pump.

[0050] Step 250, if the judgment result is no, turn on the internal charge pump to supply power.

[0051] Step 260, after turning on...

Embodiment 3

[0057] image 3 It is a schematic structural diagram of a touch screen anti-interference device provided in Embodiment 3 of the present invention, as shown in image 3 As shown, the anti-jamming device for the touch screen described in this embodiment includes: a first shutdown module 310 , a first detection module 320 , a judging module 330 and a processing module 340 .

[0058] Wherein, the first closing module 310 is used to close the power supply of the internal charge pump;

[0059] The first detection module 320 is used to detect whether an adapter is inserted into the USB interface;

[0060] The judging module 330 is used to judge whether the adapter is a standard adapter when it is detected that an adapter is plugged into the USB interface;

[0061] The processing module 340 is configured to keep turning off the power supply of the internal charge pump if the judgment result of the judgment module is yes; and to turn on the power supply of the internal charge pump if...

Abstract

The invention discloses an anti-interference method and apparatus for a touch screen. The method comprises: switching off a power supply of an internal charge pump; detecting whether an adapter is inserted in a USB interface or not; when it is detected that the adapter is inserted in the USB interface, judging whether the adapter is a standard adapter or not; if a judgment result is that the adapter is the standard adapter, keeping the switch-off of the power supply of the internal charge pump; and if the judgment result is that the adapter is not the standard adapter, switching on the power supply of the internal charge pump. According to the anti-interference method and apparatus, the power supply of the internal charge pump defaults to be switched off when the adapter is not used for charging, and the power supply of the internal charge pump is kept switched off even if the standard adapter is used for charging, so that radio-frequency performance indexes in most conditions can be ensured and the anti-interference capability of the touch screen is not influenced; and only when a non-standard adapter is used for charging, the power supply of the internal charge pump is switched on for improving the anti-interference capability of the touch screen, so that touch screen interferences caused by use of the non-standard adapter are reduced and the radio-frequency performance indexes in the most conditions are ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of touch screens, and in particular, to a method and device for anti-interference of a touch screen. Background technique [0002] Capacitive touch screens have become the standard configuration of mobile terminals such as smart phones. Capacitive touch screens are widely loved and accepted by consumers because of their convenient operation and good experience, and their touch experience and related technologies are also improving day by day. In the actual debugging and testing, as well as feedback from some users in the aftermarket, when using non-standard adapters such as counterfeit adapters or non-standard adapters for charging, the operating experience of the touch screen will be significantly deteriorated probabilistically. exceptions etc. [0003] In order to enhance the anti-interference ability of the touch screen, most of the current touch driver chips integrate a charge pump...
