触控式投影幕及触控式投影系统
Abstract:
一种触控式投影幕包括一基材、一第一触控层、一第二触控层、一反射投影膜层及一电路板。基材具有一第一面及相对于第一面的一第二面。第一触控层配置在基材的第一面上并延伸绕过基材的边缘而局部覆盖基材的第二面。第二触控层配置在第一触控层上并延伸绕过基材的边缘而局部覆盖在基材的第二面。反射投影膜层配置在第二触控层上。电路板配置在基材的第二面上并电性连接第一触控层及第二触控层。此外，一种触控式投影系统包括如上述的触控式投影幕以及一投影装置。投影装置投射一影像光束于触控式投影幕上。
Abstract(English):

A touch projection screen includes a substrate, a first touch layer, a second touch layer, a reflective projection film and a circuit board. The substrate has a first surface and a second surface. The first touch layer is disposed on the first surface and extends around an edge of the substrate to cover a part of the second surface of the substrate. The second touch layer is disposed on the first touch layer and extends around an edge of the substrate to cover a part of the second surface of the substrate. The reflective projection film is disposed on the second touch layer. The circuit board is disposed on the second surface of the substrate and electrically connects the first and second touch layers. A touch projection system includes the touch projection screen and a projection device. The projection device projects an image beam onto the touch projection screen.
