Abstract
A light emitting diode (LED) display panel includes a LED array, a color change layer, and a shutter layer disposed therebetween. The LED array is formed by multiple LEDs, defining multiple pixels. Each pixel has a corresponding LED and multiple sub-pixels. The color change layer includes multiple color change structures corresponding to the sub-pixels. The shutter layer defines multiple shutter structures correspondingly aligned to the sub-pixels and the color change structures. Each shutter structure is independently controlled to be switchable between a first state, where light emitted by the corresponding LED is prevented from reaching the corresponding color change structure, and a second state, where light emitted by the corresponding LED is allowed to reach the corresponding color change structure. For each pixel, only the shutter structure corresponding to one sub-pixel is in the second state, and the shutter structures corresponding to the other sub-pixels are in the first state.
