Title: LIGHT-EMITTING DIODE, LIGHT-EMITTING DEVICE AND DISPLAY DEVICE
Abstract:
Provided are a light-emitting diode, a light-emitting device and a display device. The light-emitting device comprises a light-emitting diode (1) and a substrate (2). The substrate (2) is coated with a bond matrix (3). The light-emitting diode (1) is provided with an anode bonding pad (11) and a cathode bonding pad (12). The surface of the anode bonding pad (11) and/or the cathode bonding pad (12) is provided with a protrusion, and the protrusion is embedded into the bond matrix (3). The anode bonding pad (11) and the cathode bonding pad (12) are fixedly connected to the substrate (2) via the bond matrix (3). According to the provided light-emitting device and display device, a bonding pad of a light-emitting diode is provided with a protrusion, thus avoiding increasing the area of the bonding pad. On the premise that the area of the bonding pad is fixed, a contact area between the bonding pad and a soldering tin is increased, so that the stability of binding the light-emitting diode and the substrate is improved, thus reducing production costs.
