Rotatably-displaying stereoscopic display

Abstract

The invention provides a rotatably-displaying stereoscopic display. The rotatably-displaying stereoscopic display comprises a linear Fresnel lens, a liquid crystal panel, a micro lens grating array which comprises a plurality of micro lenses, a solid-state light source array having a lattice structure, a synchronous driving unit, an image source and a sensing unit, wherein solid-state light source pixels, corresponding to each micro lens, in the solid-state light source array are divided into an upper light source area, a lower light source area, a left light source area and a right light source area around the center of the micro lens; the image source is connected with the liquid crystal panel and the solid-state light source array through the synchronous driving unit and provides a left-eye image and a right-eye image of a frame sequence for the liquid crystal panel; the sensing unit senses a placement angle of the display, generates a corresponding instruction and sends the instruction to the synchronous driving unit; under the control of the instruction which is sent by the sensing unit, according to the frame sequence of the left-eye image and the right-eye image, the synchronous driving unit selectively controls the solid-state light source pixels which correspond to one of the upper light source area, the lower light source area, the left light source area and the right light source area to be started; and the linear Fresnel lens is used for respectively converging time sequence light paths which are separated from the micro lens grating array to realize the stereoscopic display of the images.

Description

technical field [0001] The invention relates to a three-dimensional stereo display technology, in particular to a rotatable stereo display. Background technique [0002] With the continuous development of multimedia technology, users have higher and higher requirements for multimedia, and the need to experience smoother three-dimensional (3D) images needs to be resolved urgently. [0003] When people's naked eyes look at an object, the two eyes look at the object from two angles. Due to the different angles, the two pictures seen are slightly different. The brain mixes the two pictures seen by the eyes into a complete picture. screen, and perceive spatial information according to their differences, and then produce a three-dimensional visual effect. [0004] In the field of multimedia technology, there are many types of three-dimensional display technologies, and the most widely used ones are mainly divided into two types: glasses type and naked eye type. Glasses-type 3D s...

Problems solved by technology

[0005] In a naked-eye 3D stereoscopic display technology, the left and right separation effect of the optical path is realized through the timing control of the side backlight, the light guide plate, and the 3D stretch film, so that the viewer can watch the stereoscopic image. Due to the narrow viewing angle of this technology It has been applied to a certain extent in small handheld devices, such as mobile phones, mobile PCs, handheld audio-visual terminals, etc. However, since the optical path can only be separated left and right and cannot be separated up and down, this technology cannot yet rotate the screen at a 90-degree angle 3D Stereoscopic Display
