Problems solved by technology

[0003] However, the disadvantage of the resistive touch screen is that there is a layer of outer film on the resistive touch screen, and the outer film is easily scratched, thus causing the touch screen to be unusable.
In particular, when the user operates on the resistive touch screen, it is easy to cause damage to the screen with excessive force, which greatly increases the damage rate of the screen and greatly shortens its service life.
[0004] There is no proper method in the current technology to prevent the screen from being damaged due to excessive force when the user operates on the resistive touch screen

Embodiment Construction

[0015] The purpose of the present invention is to issue a warning to remind the user to use less force in the next operation when the user operates the resistive touch screen with excessive force, so as to protect the resistive touch screen from being damaged due to excessive force of the user. First, the theoretical basis of the present invention will be described below.

[0016] Resistive touch screen: It is a structure of film and glass. The adjacent side of film and glass is coated with ITO (Indium Tin Oxides, nanometer indium tin metal oxide) coating. ITO has good conductivity and transparency. When touch operation, the ITO on the lower layer of the film will touch the ITO on the upper layer of the glass, and the corresponding electrical signal will be transmitted through the sensor, sent to the processor through the conversion circuit, and converted into the X and Y values ​​on the screen through calculation, and the point is completed. The selected action is displayed o...

Abstract

The invention discloses a method for protecting a resistance-type touch screen. The method comprises the following steps of: setting the priority level of an alarm sound, an alarm pressure level threshold value and a pressure level corresponding to each resistance value of a contact resistor; when a user touches the surface of the resistance-type touch screen and applies a certain pressure, acquiring parameter information and the position information of a touch point; calculating the value of the contact resistor produced by touching the resistance-type touch screen; converting the calculated value of the touch resistor into a corresponding pressure level; and when the converted pressure level is not smaller than the alarm pressure level threshold value, making an alarm sound for reminding the user of excessively large force. The invention also provides a system for protecting the resistance-type touch screen. By adopting the method and the system, the resistance-type touch screen can be protected from being damaged by excessively large force of the user.

Description

technical field [0001] The invention relates to a protection system and method for a resistive touch screen. Background technique [0002] At present, mobile phones with touch screens have become a major fashion trend, including resistive touch screens. Resistive touch screens have many advantages. Its screen and control system are relatively cheap, and the response sensitivity is also good. It is completely isolated from the outside world. Environment, not afraid of dust and water vapor, can adapt to various harsh environments. It can be touched with any object and has good stability. [0003] However, the disadvantage of the resistive touch screen is that there is an outer film on the resistive touch screen, and the outer film is easily scratched, thus making the touch screen unusable. In particular, when the user operates on the resistive touch screen, excessive force may easily cause damage to the screen, greatly increasing the damage rate of the screen, and greatly sh...
