在前面板的右侧提供了一个减光控制旋扭，由此也可以激发灯泡试验。
A dimmer control knob is provided on the right side of the front panel which also activates the lamp test.
继续沿其路径，这部分的s偏振光将灯泡反光罩反射两次，最终由偏振分光镜得到垂直反射到液晶面板。
Continuing along its path, this portion of s-polarized light would be reflected twice by the lamp reflector, and would finally be reflected perpendicularly, by the beam splitter, toward the LCD panel.
