The operation principle of luminancecontrol of field emission display(FED) is introduced based on the modulating characteristic and the feature of matrix addressing.
根据场发射显示器（FED）显示单元的调制特性和矩阵寻址方式特点，分析了其亮度控制的原理和实现方法。

However, with overall consideration of design, 4000K is the only colour temperature used in this project. Intense and dimmed lights are simply achieved through luminancecontrol.
而我们的灯光设计从总体考虑，却单单使用4000k，用亮度控制，形成最纯粹的光的强弱变化；

The LED display control device uses a simpler display driving circuit, so that display luminance of displayed content is even, and the whole display is harmonious.
