A display apparatus includes a display system and a control system. The display system includes pixel units and a network interface based on a network protocol. The pixel units are arranged in a matrix and each of the pixel units includes solid state light emitting elements. The control system includes a control module, an input module, and an output module. The output module is electronically coupled to the network interface. The control system is configured to receive an input signal through the input module, generate a corresponding control signal by the control module, and output the control signal by the output module to the display system via the network interface according to the network protocol to control the display contents of the display system.
