Problems solved by technology

The disadvantage of this technology is that the pixels of the picture at a glance are only half of the screen at most, and the pixel resolution of the picture is low and not clear enough
The disadvantage of this technology is that the separation between the left and right eyes is low, the three-dimensional effect is not strong, and it is easy to dizziness

Abstract

The invention discloses a stereoscopic display, which comprises a liquid crystal display (LCD), a backlight polaroid, a light-emitting diode (LED) backlight source A, an LED backlight source B and a control unit. A display control method comprises the following steps of: alternatively displaying pictures shot by a stereoscopic camera from left eye pictures to right eye pictures through the LCD; and controlling the LED backlight source A and the LED backlight source B to emit light in the left eye pictures and the right eye pictures, wherein light rays emitted by the LED backlight source A andthe LED backlight source B pass through linear polaroid elements with mutually vertical polarization directions in the backlight polaroid; formed polarized light passes through the LCD; an observer can alternatively see the left eye pictures and the right eye pictures shot by the stereoscopic camera with a left eye and a right eye by wearing linear polaroid eyeglasses with mutually vertical polarization directions on the left eye and the right eye; and a stereoscopic image can be seen by brain processing of a human body. The stereoscopic display is easy to realize, has high stereoscopic impression and high picture quality, makes watching comfortable and can be applied to occasions such as televisions, computer displays, digital photo frames and the like.

Description

【Technical field】 [0001] The invention relates to a display, and in particular to a three-dimensional display which utilizes time-division alternately changing polarized light to provide a backlight for an LCD liquid crystal screen, and the display can be used for displaying 2-dimensional images at the same time. Can be used in TV, computer monitor, digital photo frame and other applications. 【Background technique】 [0002] At present, the technologies used for stereoscopic displays mainly include the following types: [0003] Dual-screen grating screen technology: Two screens are used to display, one screen displays the left-eye image, and the other displays the right-eye image, and the two screens are respectively pasted with polarizers with mutually perpendicular polarization directions. The observer wears polarized glasses to obtain left-eye images in the left eye. The eye image, the right eye image is obtained in the right eye, and the stereoscopic image is seen throug...
