摘要： The embodiment of the present application provides a display device and method, which relates to the technical field of virtual reality and intends to solve the problem of poor realistic effect of an image displayed by an existing display device. The device includes: a processor, a display screen component, and a half-transmitting and half-reflecting mirror. The display screen component includes a close-range display screen and a long-range display screen. A distance from the close-range display screen to the half-transmitting and half-reflecting mirror is shorter than a distance from the long-range display screen to the half-transmitting and half-reflecting mirror. The processor is used for sending a close-range image among an image to the close-range display screen for display and sending a long-range image among the image to the long-range display screen for display. The half-transmitting and half-reflecting mirror is used for reflecting and transmitting light emitted from the close-range display screen and light emitted from the long-range display screen. By implementing the embodiment of the scheme, the realistic effect of an image may be enhanced.
