Abstract
A full-color display panel includes a plurality of sub-pixel units. The sub-pixel unit includes an LED unit and a filter layer transmitting light of a specific color. The LED unit includes an LED semiconductor chip emitting light of a specific color. The LED semiconductor chips of the plurality of sub-pixel units are homochromatic LED semiconductor chips emitting light of a same color. In each sub-pixel unit, a position of the filter layer corresponds to a position of the LED semiconductor chip, and the filter layer is located on a side of the LED semiconductor chip that emits light.
