日本航空电子工业公司成功开发出最新结构的光学触屏“UP－JAB4－B”。该光学触屏的结构是在X方向和Y方向上，于液晶面板边缘部位的一边配置反射板，而另一边侧配置发光元器件和光电检测元器件，这和原有光学触屏相比，可减小触屏的边缘面积，可降低30％的制造成本。 最新结
JAL Corporation has successfully developed the UP-JAB4-B optical touch panel with the latest structure. The structure of the optical touch panel is such that the reflection plate is arranged on one side of the edge of the liquid crystal panel in the X direction and the Y direction and the light emitting components and the photodetection components are arranged on the other side. Compared with the original optical touch panel, Can reduce the touch screen edge area, can reduce manufacturing costs by 30%. The latest knot
