Abstract:
1. An image display apparatus, comprising: a light source unit to include at least one light source; an optical unit to generate a directional light using a light projected from the light source unit; a variable diffuser unit including a variable diffuser, wherein the variable diffuser unit controls the variable diffuser to selectively be in one of a transparent state and a diffusing state depending on a presence or absence of power to thereby selectively transmit and diffuse the directional light; a pixel unit to selectively generate three-dimensional (3D) images and two dimensional (2D) images corresponding to the control of the variable diffuser by the variable diffuser unit; a vertical diffusion unit to diffuse the 3D images in a vertical direction; and a high-speed switching control unit to high-speed switch the variable diffuser between the transparent state and the diffusing state to control the 2D images and the 3D images to be simultaneously outputted.
