Description

A stereoscopic display device and imaging method thereof

technical field

The invention belongs to the field of stereoscopic display, and in particular relates to a stereoscopic display device and an imaging method thereof.

Background technique

With the development of stereoscopic display technology, 3D display becomes more and more popular in daily life. The current stereoscopic display technologies mainly include glasses-type, naked-eye, volumetric display, etc. Among them, the glasses-type stereoscopic display technology has been industrialized, but due to many disadvantages, for example, 3D glasses will bring obvious discomfort to facial organs when watching 3D programs. Comfort, especially for myopia patients is more serious, so naked-eye stereoscopic display technology immediately received great attention. Since the naked-eye stereoscopic display technology is free from the shackles of glasses, it has high viewing comfort and is easily accepted by users. Famous scientific research institutions and enterprises at home and abroad are conducting related technical research and product development.

The basic principle of the mainstream naked-eye stereoscopic display technology is to display a stereoscopic image with parallax on the LCD screen, and then use a slit grating or a lenticular lens as a parallax segmentation device, the left and right eyes of the viewer will receive the stereoscopic image with parallax, and It is synthesized in the human brain and produces a three-dimensional perception. In this display technology, after the grating design is completed, a matching naked-eye 3D image is generated by software and displayed on the LCD screen to produce a three-dimensional effect.

As shown in FIG. 1 and FIG. 2 , it is a structural schematic view of an existing grating type stereoscopic display. The grating-type stereoscopic display needs to be formed by adding a grating in front of the flat-panel display 1 (including ordinary liquid crystal display LCD, plasma display PDP, field emission display FED, organic electroluminescence display OLED, etc.), and the grating can be divided into cylindrical grating 2 and The slit grating 3 and the cylindrical grating 2 are also called cylindrical lens array grating or cylindrical lens, and the slit grating 3 is also called parallax barrier array grating or slit baffle. Due to the periodic interference between the grating and the pixel array of the flat-panel display, the image generated by the pixel array of the flat-panel display will form moiré in the displayed image after passing through the grating. Obviously, the effect of this moiré phenomenon on the three-dimensional image It has a great impact, which will destroy the appreciation of the image, seriously affect the visual effect, and cause the viewer to feel uncomfortable.

In order to solve the moiré phenomenon, Philips proposed a stereoscopic display device in US Patent No. 6,064,424. As shown in FIG. 3 , it is a schematic diagram of the relationship between the display array elements and the parallel lens elements of the display panel of the stereoscopic display device. The display array element 10 includes display units 12 formed in rows and columns, and an array 15 formed of lenticular lenses 16 located on the display array element 10 . The lenticular lens 16 is placed obliquely with respect to the column direction (Y) of the display unit, and the angle between the direction L of the lenticular lens 16 and the Y direction is α, so as to reduce the occurrence of moiré. However, this stereoscopic display device only changes the arrangement of the pixel array, but does not change the arrangement of the shading lines 18 (that is, the black matrix) between the display units, and the shading line grating formed by the shading lines still exists.

The pixel arrangement and order of the LCD screen are the basis of the raster design and signal generation. Most of the currently known technical solutions are based on the conventional arrangement order of RGB pixels, and the pixels extracted from the same original 2D sub-image in the generated stereogram are arranged in a vertical direction. Although this arrangement is simple and easy to implement, it is easy to unbalance the resolution changes in the horizontal direction and the vertical direction, and when the grating is added to the front, serious moiré fringes will be generated, which will affect the image quality.
