当所述发射端装置发射的光束是不可见光时， 所述不可见光具有一定强度， 如红外线或紫外线等等， 所述光线感应膜感知所述不可见光束投射的位置， 所 述接收端装置的显示屏幕立即在所述不可见光束投射的位置处显示一个光标类 似的图案。 用户移动遥控器， 投射到所述显示屏幕上的光点及光束也跟着移动， 同时所述接收端装置随时根据所述光线感应膜感知到的光束点的位置即时刷新 显示屏幕上的光标图案， 用以给用户指示。
当所述发射端装置发射的光束是可见光及不可见光的混合光束时， 可见光 用来给与用户指示， 不可见光用来让所述光线感应膜感知光束照射点的坐标位 置， 用户移动遥控器， 投射到所述显示屏幕上的混合光点及光束也跟着移动， 用户通过混合光束所形成的混合光点对界面元素进行操作。
所述光线感应膜可以包括导电层、 具有均匀阻值的电阻层以及具有光敏特 性的光导层， 即所述光线感应膜可以分为三层， 第一层为均勾阻值的电阻层， 此层的电阻值是不变的且均勾分布的； 第二层为具有光敏特性的光导层， 此层 特性是没有光束照射时候电阻很大， 一旦有光束照射其阻值迅速下降到很小； 第三层为电阻值可以忽略的导电层， 此层的电阻很小， 几乎可以忽略不计； 所 述光导层被所述光束照射后将连通所述电阻层与所述导电层， 以使所述光线感 应膜感知所述光束点的位置， 并由所述接收端装置根据所述电阻层的电阻值提 取所述光束点在所述光线感应膜上的位置参数。 例如， 当光束从第一层的某个 点射入后， 设所述光束照射到第一层的点为 A点， 设所述光束照射到第二层的 点为 B点， 由于第二层在光束照射后电阻会迅速下降到艮小， 所以 B点电阻降 到艮小， 也就相当于第一层的 A点通过第二层电阻 ^艮小的 B点与第三层导通。 此时， 所述接收端装置提取所述 A点的电阻值， 即提取所述光束点在所述光线 感应膜上的位置参数， 所述接收端装置并根据所述位置参数计算出所述光束点 的位置坐标， 以使接收端装置根据所述位置坐标对界面元素进行定位。
所述接收端装置 2, 还用于接收所述发射端装置发送的按键动作信息， 并根 据所述按键动作信息和所述位置坐标执行所述光束点在所述位置坐标处的操 作。
由于所述发射端装置 1 是通过发射光线来让所述光线感应膜进行感应的， 而所述显示屏幕同样也会发光。 为了避免这二者之间产生干扰使所述光线感应 膜失效， 可以有以下三种应对措施加以解决：
第一种， 提高所述发射端装置 1 的光线发射强度， 从而使光束照射到所述 光线感应膜之上的时候， 所述光线感应膜有较大的感知度。
第二种， 采用所述显示屏幕不能发射的光语段光线， 如紫外线等等。
第三种， 在所述光线感应膜和所述显示屏幕之间加一层过滤膜， 如同眼睛 片上的紫外线过滤膜一样， 降低所述显示屏幕发出光线对所述光线感应膜的影 响。
