The light-emitting diode chip includes a first epitaxial light-emitting structure; a reflective layer at a side of the first epitaxial light-emitting structure; a second epitaxial light-emitting structure located at a side of the reflective layer which faces away from the first epitaxial light-emitting structure; and a first polar electrode and a second polar electrode electrically connecting semiconductor layers having first polarities and semiconductor layers having second polarities in the first epitaxial light-emitting structure and the second epitaxial light-emitting structure, respectively.

Abstract: A display substrate and a display panel are provided. The display substrate includes: a base including a front surface, a back surface and a side surface; a driving circuit layer disposed on the front surface; a back electrode disposed on the back surface; a side printed wire electrically connected to the driving circuit layer, the side printed wire extends to the back electrode from the side surface and is electrically connected to the back electrode, the side printed wire includes a wire top portion located on a side of the driving circuit layer facing away from the base; and a bonding adhesive layer disposed overlying the side of the driving circuit layer facing away from the base, the bonding adhesive layer is further in contact with and covers the wire top portion. The display substrate and the display panel can solve a problem of excessive height in a non-display area.

Abstract: A compensation circuit and a driving circuit of light-emitting elements, and a light-emitting diode (LED) display device are provided. In the compensation circuit, a first compensation switching device is disposed between a first pixel unit and a second pixel unit, and a second compensation switching device is disposed between a second pixel unit and a third pixel unit. When the first compensation switching device is turned on, the first pixel unit is electrically connected to the second pixel unit to provide compensation current to the second pixel unit. When the second compensation switching device is turned on, the third pixel unit is electrically connected to the second pixel unit to provide compensation current to the second pixel unit. Through the compensation circuit, the second pixel unit can be ensured to have a larger operating current range and emit higher luminous intensity, and power consumption of switching elements is reduced.
