背景技术
等离子电视由于具有重量轻、抗干扰能力强、图像清晰和色彩鲜亮等优点受到越来越多的消费者青睐,然而对于等离子电视的控制目前还主要停留在传统的遥控器控制上,这大大限制了等离子电视的应用。
目前广泛使用的触摸屏幕技术是基于电容屏上电容的变化来判断接触物体在屏幕上滑动的位置,或者基于电阻屏上电阻的变化来判断接触物体在屏幕上的滑动的位置。但是这些方案对于屏幕巨大的电视机来说成本过于昂贵。
发明内容
有鉴于此,本发明提供了一种等离子电视机的控制方法、一种蓝牙触控笔和一种等离子电视机,实现了一种新的大屏幕等离子电视机的触摸控制方案,且该方案的用户体验好,成本低。
为达到上述目的,本发明的技术方案是这样实现的:

具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施方式作进一步地详细描述。
图1是本发明实施例中的一种等离子电视机的控制方法的流程图。如图1所示,该方法包括:
101,设置等离子电视机屏幕的所有或部分像素点发出带有像素位置信息的光信号。
本步骤中,即可以设置等离子电视机屏幕的所有像素点发出带有像素位置信息的光信号,也可以设置等离子电视机屏幕的部分像素点发出带有像素位置信息的光信号,如可以设置等离子电视机屏幕上的每行(或每列)中的相间隔的像素点发出带有像素位置信息的光信号。例如,在每一行中,奇数位的像素点发出带有像素位置信息的光信号,而偶数位的像素点的光信号不需要带有像素位置信息,和以往的形式一样无需改变。
本步骤中,像素位置信息的具体形式可以根据实际情况进行设置,在本发明的一个实施例中,像素位置信息具体为:刷屏同步信号的时间点、刷像素所在行的时间点和刷像素所在列的时间点。
等离子电视机每完成一次刷屏的时间是固定的,比如说15.6ms,这里刷屏同步信号的时间点就是每刷一次屏的开始时间。等离子电视机刷每一行的时间点是不同的,刷每一列的时间点也是不同的。
102,触控笔通过与所述屏幕的接触接收光信号,根据光信号中的像素位置信息计算出与屏幕的接触点位置的像素坐标值,并将所计算出的像素坐标值通过蓝牙传输方式发送给等离子电视机。
本步骤中,触控笔的光耦合器件通过与所述屏幕的接触采集光信号,所述触控笔的滤波放大电路对所采集的光信号进行滤波放大整形处理;所述触控笔的主控制器根据滤波放大整形处理后的光信号中的像素位置信息计算出像素坐标值,具体来说:根据刷像素所在行的时间点与刷屏同步信号的时间点的时间差得到像素的纵坐标值,根据刷像素所在列的时间点与刷屏同步信号的时间点的时间差得到像素的横坐标值。
具体来说,根据刷像素所在行的时间点与刷屏同步信号的时间点的时间差可以确定像素点所在的行,即可以确定像素的纵坐标值,再根据刷像素所在列的时间点与刷屏同步信号的时间点的时间差可以确定像素所在的列,即可以确定像素的横坐标值。
所述触控笔的蓝牙射频模块将计算出的像素坐标值通过蓝牙无线传输方式发送给等离子电视机。
103,等离子电视机根据所接收的像素坐标值进行相应操作。
本步骤中,等离子电视机根据所接收的像素坐标值,执行预设的操作(如触控笔点的位置是关闭某个窗口等)或者在对应像素位置进行绘画显示。
图1所示的方法,不需要改变电视机的屏幕,而只需要改变电视机的刷屏时光信号的格式,在光信号接收端采用低成本的光耦合器件和主控制器芯片完成等离子电视光信号的采集和数据处理,并采用蓝牙方式实现数据的无线传输,电视机收到像素坐标值后进行显示或进行相应的操作。
例如可以实现如下的目的:若将笔头轻触电视机屏幕,相当于鼠标的单击操作;若使用笔头双击电视机屏幕,相当于电脑上的双击操作;若将笔头按下并在屏幕上移动,相当于在电脑上进行绘画操作。图2是本发明实施例中的使用蓝牙触控笔在等离子电视机屏幕上进行绘画的一个示意图。蓝牙触控笔202在等离子电视机201的屏幕上进行绘画,触控笔202在屏幕上的任何移动动作都会在电视机屏幕上显示出来。
图3是本发明实施例中的一种蓝牙触控笔的结构示意图。如图3所示,蓝牙触控笔主要包括:光耦合器件301、滤波放大电路302、主控制器303和蓝牙射频模块304,其中:
光耦合器件301,用于通过与等离子电视机屏幕的接触采集带有像素位置信息的光信号;
滤波放大电路302,用于对光耦合器件301采集的光信号进行滤波放大整形处理后发送给主控制器303;
主控制器303,用于根据所接收的光信号中的像素位置信息计算出光耦合器件301与屏幕的接触点位置的像素坐标值;
蓝牙射频模块304,用于将主控制器303所计算出的像素坐标值通过蓝牙无线传输方式发送给等离子电视机。
在图3所示的蓝牙触控笔中,光耦合器件301,通过与等离子电视机屏幕的接触采集携带有刷屏同步信号的时间点、刷像素所在行的时间点和刷像素所在列的时间点的光信号;
主控制器303,根据刷像素所在行的时间点与刷屏同步信号的时间点的时间差得到像素的纵坐标值,根据刷像素所在列的时间点与刷屏同步信号的时间点的时间差得到像素的横坐标值。
图3所示的蓝牙触控笔还进一步包括:
控制按键305,用于控制蓝牙触控笔的开关机、蓝牙连接和光耦合器件的开关;
指示灯306。
此外,蓝牙触控笔还可以包括电池、晶振、存储器和USB充电升级端口等其他的部件。
图4是蓝牙触控笔的工作状态转换示意图。如图4所示,本发明中的蓝牙触控笔有6种工作状态,分别为:关机、配对、清除配对列表、运行、休眠和重连。各状态之间的转化关系如图4所示。
在工作时,首先建立蓝牙触控笔和等离子电视机之间的蓝牙连接。首次连接时,蓝牙触控笔进入主动搜索模式,搜索支持蓝牙的电视机,搜索结束后自动连接与其最近的电视机。如果之前建立过连接则开机后蓝牙触控笔会自动重连上次连接过的电视机。蓝牙连接成功后,用户可以通过触控笔对等离子电视机屏幕上任一点的接触,来进行控制,还可以在屏幕的文本窗中进行书写、绘画等操作。触控笔一段时间不用将自动进入低功耗模式,若使用者需要再次使用触控笔,拿起笔在屏幕上点击一下,即可立即使用。
图5是本发明实施例中的一种等离子电视机的结构示意图。如图5所示,该等离子电视机包括:刷屏设置模块501、屏幕502、蓝牙接收模块503和操作处理模块504,其中:
刷屏设置模块501,用于设置屏幕502的所有或部分像素点发出带有像素位置信息的光信号;
蓝牙接收模块503,用于接收蓝牙触控笔发送的像素坐标值,并将像素坐标值发送给操作处理模块504;
