Abstract: A light-emitting device, a light-emitting substrate, and a method for manufacturing the light-emitting device. The light-emitting device includes at least one light-emitting structure. The light-emitting structure includes: a first semiconductor layer; a light-emitting layer; a second semiconductor layer, doping ions of the second semiconductor layer and a first semiconductor layer being oppositely charged; a barrier structure provided with an opening for exposing the second semiconductor layer, the orthographic projection of the opening on the base substrate being located in the orthographic projection of the light-emitting layer on the base substrate, and the area of the opening being smaller than that of the light-emitting layer; and a landing electrode located on the side of the barrier structure facing away from the second semiconductor layer, the landing electrode being in contact with the second semiconductor layer by means of the opening.

Abstract: Provided are an automatic parking method, device and system, relating to the technical field of vehicles. The method comprises: receiving operating information input by a user on the condition of receiving an automatic parking start instruction (101); generating a parking control instruction according to the operating information (102); and sending the parking control instruction to a vehicle for the vehicle to complete an automatic parking operation according to the parking control instruction (103). According to the disclosure, in the process of controlling the vehicle to automatically park, a mobile terminal converts the operating information with large data capacity input by the user in the mobile terminal into the parking control instruction with small data capacity, and only sends the parking control instruction to an automatic parking system controller for the vehicle to complete automatic parking.
