Problems solved by technology

The current common electrode is also made of the same material, that is, indium tin oxide (ITO). However, the material of indium tin oxide (ITO) is less ductile and tough, which easily increases the difficulty of the display panel common electrode process and thus reduces the quality of the display panel.

Abstract

A display device includes a driving substrate, a plurality of light emitting elements, and a plurality of metal common electrodes. The light emitting elements are dispersively arranged on the drivingsubstrate, and each light emitting element includes an epitaxial structure layer and a first type electrode and a second type electrode arranged on the epitaxial structure layer. A metal common electrode is dispose dispersedly on that drive substrate and contacts a portion of the second type electrode of each light emit element to form an ohmic contact.

Description

technical field [0001] The invention relates to a display device, in particular to a display device using light-emitting diodes as display pixels. Background technique [0002] In a general display panel, both the common electrode and the light-emitting diode are arranged in the display area, wherein the light-emitting diode is located in each pixel area and is electrically connected to the common electrode, and the display is made by the voltage difference between the common electrode and the light-emitting diode. The state of the media layer changes to display. At present, in the manufacture of light emitting diodes, most people choose Indium Tin Oxide (ITO), which has a high work function of 4.5eV-5.3eV, stable properties and light transmission, as the electrode material. The current common electrode is also made of the same material, that is, indium tin oxide (ITO). However, the material of indium tin oxide (ITO) is less ductile and tough, and it is easy to increase the...
