The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. The touch-operated mobile terminal includes a resistive touch screen and a stylus. The user uses the stylus to click on the resistive touch screen, and the change in the pressure and the change in the contact area can generate different resistances and position intervals. The processor of the mobile terminal has different resistances. And the position interval analyzes the user's operational intent and executes various instructions accordingly. 1 is a diagram showing an implementation of an eraser function based on a resistive touch screen according to an embodiment of the invention. As shown in FIG. 1 , the eraser function implementation method includes the following processing: Step 4: S: Responding to a user's touch operation on the resistive touch display of the mobile terminal, calculating a resistance value of the touch point; Step S104: determining the resistance Whether the value satisfies the erasing condition; Step S106: measuring the position interval of the touch point when the resistance value satisfies the erasing condition; and step S108: performing an erasing operation on the character in the position interval. In the related art, the user deletes the wrong character one by one by using the button on the resistive touch screen, which is inconvenient to operate and has a low experience. With the technical solution provided in the above embodiments, the eraser function can be implemented on the mobile terminal, so that the user can conveniently erase the object. The deleted characters effectively improve the user experience. In the above step S102, the resistance value of the touch point is calculated, and the calculation method in the related art can be used, which will be described below in conjunction with FIG. 2. 2 is a circuit schematic diagram of a resistive touch screen. As shown in FIG. 2, the resistive touch screen comprises two transparent layers stacked one on top of the other, generally composed of two transparent resistive materials having the same surface resistance. An elastic material is usually also used to separate the two layers. When the pressure on the surface of the touch screen (such as pressing through a pen tip or finger) is large enough, contact is made between the top layer and the bottom layer. For the resistive touch screen that receives the touch operation command, the resistance value Rtouch corresponding to the touch pressure can be calculated. The specific calculation method is as follows:
( 1 )将 X-接地, 在 X+加驱动电压 Vdriver, 在 Y+测得电压值 Vx-, 计 算得 Rx-= ( Vx- * Rplate ) /Vdriver, 其中, 上述 Rplate是一个固定值, 为 Rx-和 Rx+之和。 (1) X-ground, at X+ plus drive voltage Vdriver, at Y+ measured voltage value Vx-, Calculate Rx-= ( Vx- * Rplate ) /Vdriver, where Rplate is a fixed value and is the sum of Rx- and Rx+.
( 2 ) 将 X-接地, 在 Y+力口驱动电压 Vdriver, 在 X+测得电压值 Vzl; (2) The X-ground is grounded, the voltage is driven at the Y+ port Vdriver, and the voltage value measured at X+ is Vzl;
( 3 ) 将 X-接地, Y+力口驱动电压 Vdriver, 在 Y-测得电压值 Vz2; ( 4 )计算电阻 Rtouch值: Rtouch = (Vz2-Vzl)/I= ( Vz2-Vz 1 ) *Rx-/Vz 1 , 即 Rtouch =(Vx-*Rplate/Vdriver) *(Vz2/Vzl-l)。 优选地, 步 4聚 S 104可以进一步包括以下处理: (3) X-ground, Y+ force drive voltage Vdriver, measured voltage value Vz2 at Y-; (4) Calculate resistance Rtouch value: Rtouch = (Vz2-Vzl)/I= ( Vz2-Vz 1 ) *Rx -/Vz 1 , ie Rtouch = (Vx-*Rplate/Vdriver) *(Vz2/Vzl-l). Preferably, step S S 104 may further include the following processing:
( 1 ) 将电阻值与设置的阈值进行比较; (1) comparing the resistance value with the set threshold;
( 2 )根据比较结果确定需要执行擦除操作。 其中, 上述阈值可以包括: 第一阈值 (例如, R1 ); 上述步骤(2 )可以 包括: 当第一阈值 <电阻值时, 确定需要执行擦除操作。 优选地, 上述阈值还可以包括: 第二阈值 (例如, R2 ), 其中, 第二阈 值大于第一阈值, 则上述步骤 (2 ) 可以进一步包括: Rl <电阻值 < R2时, 确定需要执行擦除操作。 通过上述处理, 可以确定移动终端是否处于擦除状态下, 即用户是否需 要进行擦除操作, 为后续执行擦除操作提供了判断依据, 便于实现橡皮擦功 能。 优选地, 当电阻值大于 R2 时, 可以确定电阻式触摸屏未获取到触摸操 作指令; 当电阻值小于 R1时, 确定移动终端处于书写状态中。 移动终端的处理器可以才艮据不同电阻和位置区间分析用户的操作意图, 并相应地执行各种指令, 提高了用户体验。 在优选实施过程中, 用户需要擦除待删除字符时, 可以釆用触控笔的尾 部触摸该移动终端的电阻式触摸屏。 优选地, 可以设置触控笔的尾部的材料和接触面积, 其中, 材料的刚性 度与接触面积适合于触控笔的尾部被执行对移动终端的电阻式触摸屏的触摸 操作时, 提供满足擦除条件的电阻值。 其中, 在触控笔的尾部可以安装橡皮擦, 橡皮擦可以釆用接触面积较大 的软性材料制作, 以减小橡皮与触摸展接触时的压强, 减小实际触控点的压 力值。 在优选实施过程中, 如图 3所示, 用户完全可以按照自己的书写习惯进 行汉字、 英文等语言输入 (即釆用触控笔 14的笔头 140在电阻式触摸屏 10 上进行书写), 如果输入错误也不必担心, 该触控笔的另一头(即尾部 )就安 装有橡皮擦 142 (软性材料), 只要把笔倒转过来在错误输入的信息上面轻轻 一按就可以删除错误信息了。 优选地, 可以才艮据触控笔的尾部被执行对移动终端的电阻式触摸屏的触 摸操作时所产生的电阻值, 设置上述擦除条件。 其中, 在设置该擦除条件时, 需要确定上述区间的端点值, 例如, Rl、 R2。 对于一个电阻式触摸屏, 根据其驱动电压, 材料特性, 按压的压力大小 可以预先进行调试, 确定合适的两个电阻阈值 Rl、 R2, 用以判断是否有接 触, 如果有接触, 是为笔头接触, 还是为尾部的接触。 例如, 若触摸屏上下两层之间的电阻值 Rtouch>R2, 判断触控笔和触摸 屏之间没有接触; 若 Rl<Rtouch<R2, 则判断是用橡皮接触; 若 Rtouch<Rl, 则判断是用笔头接触。 以下结合两个优选实施例描述上述优选实施过程。 优选实施例一 (2) It is determined based on the comparison result that an erase operation needs to be performed. The foregoing threshold may include: a first threshold (eg, R1); and the foregoing step (2) may include: determining that an erase operation needs to be performed when the first threshold < resistance value. Preferably, the threshold may further include: a second threshold (for example, R2), wherein the second threshold is greater than the first threshold, the step (2) may further include: when R1 <resistance value < R2, determining that the wipe needs to be performed In addition to the operation. Through the above processing, it can be determined whether the mobile terminal is in an erase state, that is, whether the user needs to perform an erase operation, which provides a judgment basis for subsequent execution of the erase operation, and facilitates the implementation of the eraser function. Preferably, when the resistance value is greater than R2, it may be determined that the resistive touch screen does not acquire the touch operation instruction; when the resistance value is less than R1, it is determined that the mobile terminal is in the writing state. The processor of the mobile terminal can analyze the user's operation intention according to different resistances and position intervals, and execute various instructions accordingly, thereby improving the user experience. In a preferred implementation process, when the user needs to erase the character to be deleted, the tail of the stylus can be used to touch the resistive touch screen of the mobile terminal. Preferably, the material and the contact area of the tail of the stylus may be set, wherein the rigidity and the contact area of the material are suitable for the erasing when the tail of the stylus is performed on the resistive touch screen of the mobile terminal. Conditional resistance value. Wherein, an eraser can be installed at the tail of the stylus, and the eraser can be made of a soft material with a large contact area to reduce the pressure of the rubber in contact with the touch display and reduce the pressure value of the actual touch point. In the preferred implementation process, as shown in FIG. 3, the user can perform language input such as Chinese characters and English according to his own writing habits (that is, the writing head 140 of the stylus 14 is used to write on the resistive touch screen 10), if input Don't worry about the error. The other end of the stylus (ie, the tail) is equipped with an eraser 142 (soft material). You can delete the error message by simply turning the pen upside down and pressing the wrong input message. Preferably, the above-described erasing condition may be set based on the resistance value generated when the tail of the stylus is performed on the touch operation of the resistive touch screen of the mobile terminal. Wherein, when setting the erasure condition, it is necessary to determine the endpoint value of the above interval, for example, R1, R2. For a resistive touch screen, according to its driving voltage, material characteristics, the pressure of the pressing can be debugged in advance, determine the appropriate two resistance thresholds Rl, R2, to determine whether there is contact, if there is contact, it is the tip contact, Still the contact of the tail. For example, if the resistance value Rtouch>R2 between the upper and lower layers of the touch screen is judged, there is no contact between the stylus and the touch screen; if Rl<Rtouch<R2, it is judged to be contacted with rubber; if Rtouch<Rl, the judgment is used. The tip is in contact. The above preferred implementation process is described below in connection with two preferred embodiments. Preferred embodiment 1
