  "textContent": "A display apparatus includes a light-emitting component, a controller, a digital micro-mirror device, a first projection assembly and a second projection assembly. The controller is configured to alternately output a first image signal and a second image signal to the digital micro-mirror device. The digital micro-mirror device is configured such that in response to receiving the first image signal, at least one micro-lens is rotated to a respective first preset position, and that in response to receiving the second image signal, at least one micro-lens is rotated to a respective second preset position. The first projection assembly is configured to receive light reflected by the at least one micro-lens located at the respective first preset position and output a first image. The second projection assembly is configured to receive light reflected by the at least one micro-lens located at the respective second preset position and output a second image.",
