Abstract: A quantum dot light emitting diode includes: a light emitting layer, the light emitting layer including a first quantum dot layer and a second quantum dot layer which are stacked; the first quantum dot layer including a first quantum dot having a hole transporting property; and the second quantum dot layer including a second quantum dot having an electron transporting property. The first quantum dot layer having hole transporting property and the second quantum dot layer having electron transporting property are stacked. The first quantum dot layer and the second quantum dot layer not only form a quantum dot light emitting layer, but also transport holes and electrons respectively, thereby causing excitons to be recombined in the first quantum dot layer and/or the second quantum dot layer, or near the interface of the first quantum dot layer and the second quantum dot layer.

Abstract: The present disclosure provides a display panel, its driving method, and a display device. The display panel includes a first substrate and a second substrate arranged opposite to each other to form a cell, a liquid crystal layer arranged between the first substrate and the second substrate, and a pixel electrode arranged on the second substrate. A sensing electrode to which an external voltage is to be applied is arranged at a region of the first substrate corresponding to the liquid crystal layer. At a display stage, an electric field is generated between the sensing electrode to which the external voltage is applied and the pixel electrode to which a data voltage is applied, so as to drive liquid crystal molecules in the liquid crystal layer to deflect. The sensing electrode is a black matrix and/or color filter made of a conductive material and arranged on the first substrate.
