在本实施例中，智能笔微处理器11和第一红外发射器13分别设置于智能笔本体14内部，按键单元12设置于智能笔本体14表面。红外触摸框22设置于显示设备2的显示面，触摸框微处理器21和整机主控芯片23设置于显示设备2的内部。
其中，第一红外发射器13可以为红外发射灯，第二红外接收器24可以为红外接收灯管。
可选的，按键单元12可以是按钮或者选择开关(图2为按钮)。其中，按键单元的具体结构和形状本实施例不作限定。以按键单元12为按钮为例，按扭接收到用户的按压操作后，将按压操作发送至智能笔微处理器11，智能笔微处理器11可以根据该按压操作确定对应的颜色更换指令。
进一步的，整机主控芯片23通过USB和UART(Universal Asynchronous Receiver/Transmitter，通用异步收发传输器)接口(图未示)连接触摸框微处理器21，以接收触摸框微处理器21发送的颜色更换指令，并根据接收的颜色更换指令更换所述智能笔1在显示面中信号显示颜色。
在上述实施例的基础上，显示设备2的红外触摸框22还设置有第二红外发射器25，第二红外发射器25与触摸框微处理器21相连；第二红外发射器25，用于作为信号源向外发射红外信号；触摸框微处理器21，还用于编码需要向外发送的信息并传输给所述第二红外发射器25。相应的，智能笔1还包括第一红外接收器15，第一红外接收器15与智能笔微处理器11相连；第一红外接收器15，用于接收外部信号源发射的红外信号；智能笔微处理器11，还用于解码第一红外接收器15接收的红外信号。
其中，第一红外接收器15设置于智能笔本体14的内部。
可选的，第一红外接收器15可以为红外接收灯或红外光敏元件，第二红外发射器25可以为红外发射灯管。
具体的，第一红外接收器15的光敏元件(图未示)的朝向与第一红外发射器13的发射元件(图未示)的朝向相同。其中，该光敏元件和发射元件均朝向与智能笔1配合使用的显示设备2，以使智能笔1内部的第一红外接收器15及第一红外发射器13，与该显示设备2以较佳的角度进行信号交互。
可选的，图3为本发明实施例一提供的一种红外触摸框的结构示意图，如图3所示，第二红外发射器25与第二红外接收器24分别设置两列，第二红外发射器25与第二红外接收器24在红外触摸框22的内侧壁相对设置。其中，第二红外发射器25与第二红外接收器24在红外触摸框22的内侧壁相对设置，这样使得第二红外发射器25可以尽量向更大的范围发射红外信号，也使得第二红 外接收器24可以尽量接收到更大范围内的红外信号。

实施例二
图4为本发明实施例二提供的一种颜色更换方法的流程图。本实施例提供的颜色更换方法适用于上述实施例提供的交互设备。本实施例提供的颜色更换方法可以由颜色更换系统来执行，该颜色更换系统可以通过软件和/或硬件的方式实现。参考图4，本实施例提供的颜色更换方法具体包括：
S410、智能笔微处理器接收按键单元输入的按键操作，并根据所述按键操作编码对应的颜色更换指令。
具体的，颜色更换指令为更换智能笔在显示设备的显示面中信号显示颜色的指令。例如，更换智能笔的书写颜色或者光标的指示颜色。
示例性的，智能笔微处理器处于工作激活状态，其中，工作激活状态是指智能笔与显示设备完成同步后，可以进行通信的状态。
其中，智能笔微处理器中预先设定按键操作与颜色更换指令的对应关系。基于此，本实施例示例性的提出下述方案：
方案一、智能笔微处理器在接收按键单元输入的按键操作时生成颜色更换指令，并编码所述颜色更换指令。
该方案中，在接收到按键单元输入的按键操作时，智能笔微处理器生成的颜色更换指令为将当前显示颜色的下一个显示颜色确定为所述智能笔信号显示颜色。具体的，预先在显示设备中存储显示颜色排序，当显示设备接收到颜色更换指令时，就可以确定待更换的信号显示颜色。此时，不限定用户对按键单元的具体按键操作方式(比如点击或长按)，智能笔微处理器只要接收到按键单元输入的按键操作，无需解析按键操作的具体方式，直接生成上述颜色更换指令。
可选的，还可以预先在智能笔微处理器中存储显示颜色排序，当接收到按键单元输入的按键操作时，智能笔微处理器无需解析按键操作的具体方式，直 接确定将当前显示颜色的下一个显示颜色确定为所述智能笔信号显示颜色，生成的颜色更换指令中仅需包含待更换的信号显示颜色。此时，显示设备接收到颜色更换指令后，可以直接确定待更换的信号显示颜色。
方案二、智能笔微处理器在接收按键单元输入的按键操作时，解析所述按键操作以确定对应的颜色更换指令，并编码所述颜色更换指令。
该方案中，在智能笔微处理器中预先存储不同的按键操作对应的不同显示颜色。当智能笔微处理器接收按键单元输入的按键操作时，解析按键操作，以确定按键操作的具体方式，根据具体方式确定对应的显示颜色，并生成颜色更换指令。
例如，设定用户点击一次按键，显示颜色为红色；用户双击按键，显示颜色为黑色；用户长按按键，显示颜色为蓝色。智能笔微处理器接收按键单元输入的按键操作为双击按键时，确定显示颜色为黑色，生成的颜色更换指令为将智能笔信号显示颜色更换为黑色。
可选的，还可以预先在显示设备中存储不同的按键操作对应的不同显示颜色。此时，当智能笔微处理器接收按键单元输入的按键操作时，解析按键操作，以确定按键操作的具体方式，根据具体方式生成颜色更换指令。其中，颜色更换指令中包括按键操作的具体方式。显示设备接收到颜色更换指令时，根据颜色更换指令中按键操作的具体方式确定对应的显示颜色。
例如，智能笔微处理器接收按键单元输入的按键操作为双击按键时，生成颜色更换指令包括双击操作。显示设备接收到颜色更换指令时，根据双击操作确定对应的显示颜色为黑色，并将智能笔信号显示颜色更换为黑色。
上述，确定颜色更换指令后，智能笔微处理器对该颜色更换指令进行编码。其中，具体的编码规则本实施例不作限定。
S420、所述智能笔微处理器将编码后颜色更换指令传输给第一红外发射器，以通过所述第一红外发射器发射携带有编码后颜色更换指令的红外信号。
具体的，智能笔微处理器将编码后颜色更换指令传输至第一红外发射器，以使第一红外发射器发射携带有该颜色更换指令的红外信号。其中，红外信号中颜色更换指令为编码后的形式。红外信号还可以携带有其他的数据，数据的具体内容本实施例不作限定。
进一步的，第一红外发射器发射红外信号，以使交互的显示设备接收到该红外信号。
S430、触摸框微处理器解码第二红外接收器接收的红外信号，以获取所述颜色更换指令。
示例性的，显示设备的第二红外接收器接收红外信号，并将接收的红外信号发送至触摸框微处理器。触摸框微处理器解码该红外信号，以获取红外信号中携带的颜色更换指令。其中，具体的解码规则根据上述编码规则确定。
考虑到显示设备中第二红外接收器可以接收到接收范围内全部的红外信号，且无法判断接收红外信号的来源，此时，需要触摸框微处理器解码接收的红外信号，以确定是否为当前交互的智能笔发出的红外信号，并在确定为当前交互的智能笔发出的红外信号后，获取红外信号中包含的颜色更换指令。
具体的判断方法可以是：智能笔微处理器编码智能笔的特征码，并将特征码发送至第一红外发射器，以使第一红外发射器发射的红外信号中包含颜色更换指令和特征码。触摸框微处理器解码第二红外接收器接收的红外信号时，先确认是否可以在红外信号中获取特征码，并在获取到特征码时，判断该特征码是否为交互的智能笔的特征码，若是，则确认红外信号为当前交互的智能笔发出的红外信号。
其中，每个智能笔都有对应的特征码，不同智能笔对应的特征码不同。如果智能笔与显示设备是成套设备，那么智能笔与显示设备应预先相互保存对方的特征码，例如产品序列号、机器码等。可选的，也可以由用户将智能笔的特征码录入显示设备中，以使显示设备确定当前交互的智能笔的特征码。
进一步的，触摸框微处理器可以将解码得到的特征码与预存的特征码进行匹配，以确认当前接收的红外信号是否为交互的智能笔发射的红外信号，这样可以消除其他红外信号对显示设备造成的干扰。
S440、所述触摸框微处理器将所述颜色更换指令发送至整机主控芯片，以使所述整机主控芯片根据所述颜色更换指令更换智能笔在显示设备显示面中信号显示颜色。
具体的，触摸框微处理器将颜色更换指令发送至整机主控芯片，整机主控解析颜色更换指令后，确定待更换的信号显示颜色，并将显示面中智能笔的信号显示颜色更换为待更换的信号显示颜色。
本实施例的技术方案，智能笔微处理器根据接收的按键操作确定并编码对应的颜色更换指令，并将颜色更换指令通过第一红外发射器以红外信号的方式进行发射，触摸框微处理器解码第二红外接收器接收的红外信号，以获取颜色更换指令并发送至整机主控芯片，以使整机主控芯片根据颜色更换指令更换智能笔信号显示颜色，简化了智能笔的操作，实现了智能笔与显示设备间红外通信，降低了智能笔和显示设备的生产成本，消除了外界信号对显示设备的干扰，同时，实现了在显示设备的显示面中更换智能笔信号显示颜色。
实施例三
图5为本发明实施例三提供的一种颜色更换方法的流程图。本实施例在上 述实施例的基础上为优化，参考图5，本实施例提供的颜色更换方法具体包括：
S510、触摸框微处理器将智能笔识别区域信息编码并通过第二红外发射器向外发射。
示例性的，触摸框微处理器将红外触摸框的智能笔识别区域信息及红外触摸框的特征码进行编码，通过红外触摸框上的第二红外发射器将编码后得到的信息以红外信号的方式向外发射。
其中，智能笔识别区域是指红外触摸框能识别智能笔的有效识别区域，该区域是在一定范围内的一个空间区域，在本实施例中该区域的范围大小可调。
具体的，交互的智能笔与显示设备中应预先相互保存对方的特征码。
若交互的智能笔和显示设备中没有预先保存对方的特征码，则可以由用户在显示设备中添加智能笔的特征码。此时，显示设备第一次向智能笔发送的红外信号中不仅包括编码后的智能笔识别区域信息和红外触摸框的特征码，还包括编码后的智能笔的特征码。其中，可以由触摸框微处理器对智能笔的特征码进行编码。
相应的，智能笔微处理器解码该红外信号时，若确定该红外信号中包含自身的特征码，则智能笔可以确认该红外信号为发送给自己的红外信号，即进行一个简单的握手。此时，智能笔进行初始化，并保存红外触摸框的特征码和智能笔识别区域信息。
可选的，显示设备向非首次同步的智能笔发射红外信号时，触摸框微处理器仅需对红外触摸框的智能笔识别区域信息及红外触摸框的特征码信息进行编码即可。
S520、智能笔微处理器解码通过第一红外接收器接收的外部信号源发射的红外信号。
示例性的，智能笔的第一红外接收器接收到外部信号源发射的红外信号，并将该红外信号传输给智能笔微处理器，智能笔微处理器对该红外信号进行解码处理。其中，外部信号源可以为红外触摸框，或为其他可发出红外信号的设备。
考虑到第一红外接收器接收红外信号时，无法确认该红外信号的来源，因此，需要智能笔微处理器对红外信号进行解码后才能明确该红外信号的来源，并根据解码结果进行后续操作。
S530、智能笔微处理器判断通过解码所述外部信号源发射的红外信号得到的信息中是否携带有完整的智能笔识别区域信息。若携带有完整的智能笔识别区域信息，则执行S540，否则，执行S550。
具体的，智能笔中预先还存有交互显示设备的智能笔识别区域信息。智能笔微处理器将解码得到的智能笔识别区域信息和红外触摸框的特征码与预先存储的交互显示设备的智能笔识别区域信息和红外触摸框的特征码进行比对，以确认解码的智能笔识别区域信息和红外触摸框的特征码是否完整。若完整，则说明智能笔进入到该智能笔识别区域，执行S540。否则，执行S550。
需要说明的是，与步骤S510对应的，如果是初次接收到红外信号，该红外信号携带的完整的信息还应该包括智能笔自身的特征码。
S540、智能笔微处理器激活所述智能笔。执行S560。
例如，设置垂直距红外触摸框20厘米范围内为智能笔识别区域，当智能笔进入到该智能笔识别区域时，激活智能笔，整机系统自动打开电子白板应用，或其它自定义功能，例如PPT(Power Point，演示文稿)批注等。
本方案中的智能笔不是随意激活并发射红外信号，而是需要对红外信号接收方的身份进行认证，基于身份认证的激活确认能够消除信号接收时的干扰， 只有认证后的智能笔才能被响应。
S550、智能笔微处理器继续使所述智能笔保持未激活的状态。返回执行S520。
S560、智能笔微处理器接收按键单元输入的按键操作，并根据所述按键操作编码对应的颜色更换指令。
S570、智能笔微处理器编码智能笔的特征码。
其中，S570和S560中编码操作可以同时进行。
S580、智能笔微处理器将编码后颜色更换指令和智能笔的特征码传输给第一红外发射器，以通过所述第一红外发射器发射携带有编码后颜色更换指令和智能笔的特征码的红外信号。
其中，所述第一红外发射器发射的红外信号中还包括：智能笔的特征码。
S590、触摸框微处理器解码所述第二红外接收器接收的红外信号，以获取所述红外信号中携带的智能笔的特征码和颜色更换指令。
S5100、触摸框微处理器判断获取到的特征码是否与当前交互智能笔的特征码匹配。若确认获取到的特征码与当前交互智能笔的特征码匹配，则执行S5110，否则，执行S5120。
S5110、触摸框微处理器发送颜色更换指令至整机主控芯片，以使整机主控芯片根据颜色更换指令更换智能笔在显示设备显示面中信号显示颜色。
S5120、触摸框微处理器停止对当前红外信号的处理。
本实施例提供的技术方案，智能笔通过确认红外信号中智能笔识别区域信息对智能笔进行激活，显示设备通过确认智能笔特征码以执行颜色更换指令，可以消除外界信号的干扰，此外，通过红外通信方式，智能笔进入到红外触摸框的智能笔识别区域时即可激活智能笔，实现红外触摸框对智能笔的悬浮识别， 极大地提升了用户体验。
