Abstract: A display apparatus includes a display unit (2) and an image processing unit (3). The display unit may be configured to project light for a display image. The image processing unit may be configured to change polarization direction of the light for the display image and to selectively scatter or transmit the light for the display image based on the polarization direction of the light for the display image.

Abstract: A display apparatus and a method for driving the same are provided. The display apparatus includes: a timing control circuit; a display source, configured to generate a light having first display information and a light having second display information, under control of the timing control circuit, during mutually alternate first and second timings, respectively; a polarizer, configured to, under control of the timing control circuit, convert the light having the first display information into a first linearly polarized light during the first timing, and convert the light having the second display information into a second linearly polarized light during the second timing; and an optical path controller, configured to receive the first linearly polarized light and the second linearly polarized light from the polarizer, and to project the first linearly polarized light and the second linearly polarized light, spatially separate from each other, into a user's eyes.

Abstract: A display system and an image display method are disclosed. The display system includes a display image export device, a display image import device and a light intensity control device. The display image export device includes a display side and an opposite side; at least part of the display image export device is able to receive at least part of a surrounding image for the opposite side at the display side; and the display image export device can further display a first image at the display side. The display image import device can receive light of the first image, and to transmit the tight of the first image to the display image export device. The light intensity control device can control at least one of an intensity of light of the surrounding image and an intensity of the light of the first image.
