图3为表面声波触摸屏的结构示意图。 FIG 3 is a schematic view of a surface acoustic wave touch screen. 表面声波触摸屏由触摸屏、声波发生器、声波接收器组成。 A surface acoustic wave touch screen of a touch screen, sound generator, an acoustic wave receiver. 触摸屏四周布满玻璃屏的四个周边则刻有呈45度角由疏到密间隔精密的反射条纹。 Touch screen surrounds with four peripheral glass screen is engraved with a 45 degree angle precision reflective stripes spaced from sparse to dense. 其中,声波发生器能发送一种高频声波跨越屏幕表面,当手指触及时,触点上的声波即被阻止,由此确定坐标位置。 Wherein the acoustic wave generator A high-frequency sound waves can be transmitted across the screen surface, when the finger touches, i.e. to prevent the acoustic wave at the contact, thereby determining a coordinate position. 表面声波触摸屏不受温度、湿度等环境因素影响,分辨率极高, 有极好的防刮性。 A surface acoustic wave touch screen independent of temperature, humidity and other environmental factors, high resolution, excellent scratch resistance.

本实用新型即是考虑到表面声波触摸屏的上述优点,在坐标和压力输入装置即电磁式手写装置中增加表面声波触摸屏,这样,用户使用本装置时即有两种输入模式, 一是用电磁笔在屏幕上书写输入,二是触摸输入。 The present invention i.e. in view of the above-described advantages a surface acoustic wave touch screen, the apparatus i.e. electromagnetic handwriting device coordinates and the pressure increase in the input surface acoustic wave touch screen, so that there are two kinds of input mode when the user uses the present apparatus, one electromagnetic pen written input on the screen, and second touch input.

实际使用中,本装置实时检测信息的输入及信息输入的模式,表面声波触摸屏判断信息输入是否是触摸输入,电磁屏判断是否是电磁笔输入。 In actual use, real-time detection of the present apparatus and the information input mode of the input information, determines a surface acoustic wave touch screen input is a touch input information, determines whether the electromagnetic screen is an electromagnetic pen input. 图4为本实用新型判断信息输入模式的流程图,具体判断过程如下: Analyzing a flowchart of the present invention in FIG. 4 the information input mode, determines the specific process is as follows:

当使用电磁笔输入时,控制模块控制电磁屏进行坐标和压力的检测。 When using an electromagnetic pen, the control module controls the detected electromagnetic screen coordinates and pressure. 具体检测过程是:电磁屏X方向线圈和Y方向线圈分别作为发射电路和接收电路,电磁笔中的谐振电路与电磁屏中的发射电路产生谐振,谐振信号再被电磁屏上的接收电路接收,电磁屏根据返回信号的强弱变化或频率、 相位的变化,计算出电磁笔在电磁屏中的相对位置和压力。 Specific detection process: electromagnetic screen X-direction coil and the Y-direction coils are transmitting and receiving circuits, electromagnetic pen resonance circuit with electromagnetic screen transmission circuit generates a resonance, the resonant signal is then received by the receiver circuit on the electromagnetic screen as, electromagnetic screen according to the change or changes in the strength to return the frequency of the phase signal to calculate the relative positions of the electromagnetic pen pressure and the electromagnetic screen.

当触摸输入时,控制模块控制表面声波触摸屏进行坐标检测。 When the touch input, the control module controls a surface acoustic wave touch screen coordinate detection. 具体检 Specific inspection

测过程是:声波发射器把控制模块发送的电信号转化为声波能量向触摸屏左方表面传递,然后由触摸屏玻璃板下边的一组精密反射条纹把声波能量反射成向上的均匀面传递,声波能量经过屏体表面,再由上边的反射条纹 Test procedure is: an electrical signal into the sonic transmitter control module sends a transmission to the touch surface of the panel to the left of acoustic energy, and by a set of reflective stripes precision of the touch screen below the glass reflector to the acoustic energy transmitted upwardly uniform surface, acoustic energy after the surface of the screen, and then reflected by the upper side stripes

聚成向右的线传播给x轴的声波接收器,声波接收器将返回的表面声波能 Poly into the right line to propagate the acoustic wave receiver to the x axis, the surface acoustic wave acoustic receiver will be able to return

量变为电信号。 Amount into electrical signals.

当声波发生器发射一个窄脉冲后,声波能量历经不同途径到达声波接收器,走最右边的最早到达,走最左边的最晚到达,早到达的和晚到达 When the sound waves emitted a narrow pulse generator, acoustic energy over different routes to reach the acoustic receivers, take the far right of the earliest arriving, take the leftmost latest arriving early arrival and late arrival

的这些声波能量叠加成一个较宽的波形信号,接收信号集合了所有在x轴 These superposed acoustic energy into a wide wave signal, the received signal in the set of all x-axis

方向历经长短不同路径回归的声波能量,它们在Y轴走过的路程是相同的, 但在X轴上,最远的比最近的多走了两倍X轴最大距离。 After the direction of the return path of acoustic energy of different lengths, their distance traveled in the Y axis are the same, but in the X-axis, farthest away than the maximum distance X axis twice more recently. 因此这个波形信号的时间轴反映各原始波形叠加前的位置,也就是X轴坐标。 Thus the time-axis waveforms of signals reflected each position before the original waveform is superimposed, i.e. X-axis coordinate.

发射信号与接收信号波形在没有触摸的时候,接收信号的波形与参照波形完全一样。 Transmit and receive signals in the absence of a touch waveform, the received signal waveform of the reference waveform is exactly the same. 当手指或其它能够吸收或阻挡声波能量的物体触摸屏幕时,X轴途经手指部位向上走的声波能量被部分吸收,反应在接收波形上即某一时刻位置上波形有一个衰减缺口。 When a finger or other object capable of absorbing sonic energy barrier or a touch screen, via the finger portion of the X-axis direction away acoustic energy is partially absorbed, the reaction time i.e. a position on the waveform attenuation has a gap in the received waveform.

接收波形对应手指挡住部位信号衰减了一个缺口,计算缺口位置即得触摸坐标。 Receiving the finger block portion corresponding to the waveform of a signal attenuation notch, the notch position that was calculated touch coordinate. 控制模块分析到接收信号的衰减并由缺口的位置判定X坐标, Analysis module to control the position of the received signal attenuated by the notch determination of the X coordinate,

之后Y轴同样的过程判定出触摸点的Y坐标。 After the same process determines the Y-axis Y coordinate of the touch point.

上述两种输入模式在实际使用中还可能存在以下两种情况-一是手持电磁笔在显示装置上进行书写时,由于表面声波触摸屏是放在显示装置的上方,所以使用者的手可能会与表面声波触摸屏接触,这样, 表面声波触摸屏就会检测到有触摸信息的输入,干扰电磁屏的正常工作。 The two input modes may also exist in the following two cases actual use - when one is held electromagnetic pen to write on the display device, since the surface acoustic wave touch screen is placed above the display device, the user's hand and may be contacting a surface acoustic wave touch screen such that a surface acoustic wave touch screen will detect a touch input information, interfere with the operation of the electromagnetic screen.

本实施例针对可能存在的该种情况,在控制模块中预先设置电磁笔输入模式具有更高优先级,当控制模块检测到电磁笔输入信号和触摸输入信号并存时,屏蔽表面声波触摸屏,指示电磁屏工作迸行坐标和压力的检测。 The present embodiment is directed to the case may be present, preset in the control module electromagnetic input mode has a higher priority, when the control module detects the electromagnetic signal and the pen touch input signal coexist, a surface acoustic wave touch screen shield, indicating electromagnetic detection screen work into line coordinates and pressure.

二是使用者用手指触摸输入时,手掌可能会接触显示装置,此时,表面声波触摸屏不仅会检测到手指的输入信息,还会检测到手掌的信息,因而需要屏蔽手掌信息。 Second, when the user touch input with a finger, the palm may come into contact with the display device, this time, only a surface acoustic wave touch screen detects input information on the finger, but also the information detected palm, palm information thus needs to be shielded. 本实施例在控制模块中预先设定一用于判断触摸输入面积的阈值,当控制模块检测到的输入面积大于该阈值时,输入无效, 即手掌输入信息无效。 In the present embodiment, the control module is set in advance a threshold value for determining a touch input area, when the control module detects that the input area is greater than the threshold value, the input is invalid, i.e., the input information is invalid palm. 当控制模块检测到的输入面积小于该阈值时,输入有效,表面声波触摸屏工作进行手指的坐标和压力信息的检测。 When the control module detects an input area smaller than the threshold value, the input, a surface acoustic wave touch screen working coordinate detection and finger pressure information.

作为本实用新型的第二实施例,与第一实施例不同之处在于,如图5 所示,表面声波触摸感应模块叠放在显示装置的上方,电磁感应模块叠放在显示装置的下方,由控制模块将电磁感应模块和表面声波触摸感应模块采集的坐标和压力信息处理后发送到外部操作系统。 As a second embodiment of the present invention embodiment, different from the first embodiment in that the embodiment shown in Figure 5, a surface acoustic wave touch sensor module stacked above the display device, the electromagnetic induction modules stacked below the display device, sent by the control module and a module electromagnetic induction surface acoustic wave touch sensor module and coordinates collected after the pressure information to the outside of the operating system process. 表面声波触摸感应模块包含透明表面声波触摸屏,电磁感应模块包括电磁屏,电磁屏由非透明材料制成,这样,电磁屏X、 Y方向线圈可以布置在同一层材料上。 A surface acoustic wave module including a transparent touch-sensitive surface acoustic wave touch panel, an electromagnetic induction module comprises an electromagnetic screen, electromagnetic screen is made of a non-transparent material, so that the electromagnetic screen X, Y direction coils may be arranged on the same layer of material. 本实施例的工作流程与第一实施例相同。 Workflow present embodiment is the same as the first embodiment.

本实用新型采用电磁输入和表面声波输入相结合的方式,方便多种输入模式的选用,可以达到很好的输入效果。 The present invention uses a surface acoustic wave and the electromagnetic input input combination, to facilitate selection of various input modes, input can achieve good results.
