Abstract
The utility model provides a kind of far image display device, including image source, optical module, window and shell.Image source is configured as exit image light.Optical module is set in the light path downstream of image source, including at least one free curved mirror, to receive the image light amplification and reflection of image source exit.Optical module is set in the light path downstream of window, and reflected image light is emitted by window.Image source and optical module are set in shell, and reflected image light is emitted to the outside of shell by the position of window in shell.Window includes two mutually spaced and non-light-transmitting sub-windows.The distance between the shape center of two sub-windows is 50-80mm.Or window is connected whole, and optical module deflects image light, so that the optical axis of image light reflected by free curved mirror is perpendicular to window.The embodiment of the utility model is beneficial to simplify optical module, simplify far image display device structure, reduce volume, reduce light loss, and meet different use requirements.
