摘要： A projection lens system which is arranged between an object side at which a micro-display panel is located and an image side at which a screen is located, and includes an aperture stop; a front lens group arranged at an object-side of the aperture stop and having a positive refractive power; a rear lens group arranged at an image-side of the aperture stop, the rear lens group including a first aspherical lens at a position closest to the image side and a second aspherical lens adjacent to an object-side surface of the first aspherical lens; and an aspherical mirror having a negative refractive power and reflecting light coming from the rear lens group toward the image side.

摘要： An electronic device includes a projector, an operating method of an electronic device including a projector, and a non-transitory computer-readable recording medium having recorded thereon instructions for performing the operating method. The electronic device includes a communicator configured to exchange data with an external device, a projector configured to project light; a sensor configured to measure a degree of proximity between the electronic device and an installation surface on which the electronic device is to be installed, and a controller configured to control the communicator and/or the projector based on the degree of proximity measured by the sensor.
