Embodiment Construction
[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0023] In the embodiment of the present invention, switching between 2D images and 3D images is realized by controlling the charging / discharging of the striped electrode strips located on the upper and lower substrates in the liquid crystal grating unit.
[0024] An embodiment of the present invention provides a liquid crystal grating unit, such as figure 1 and Figure 5 As shown, it includes an upper substrate 101 and a lower substrate 107;
[0025] A first grating 102 is located on the lower surface of the upper substrate 101, and a second grating 106 is located on the upper surface of the lower substrate 107; the grid of the first grating 102 is a plurality of parallel first electrode strips, and the second grating 106 is located on the upper surface...

The invention provides a liquid crystal grating unit, a display device and a display method. The liquid crystal grating unit comprises an upper substrate and a lower substrate, wherein a first grating is positioned on the lower surface of the upper substrate; a second grating is positioned on the upper surface of the lower substrate; gates of the first grating are a plurality of parallel electrode strips; gates of the second grating are a plurality of parallel electrode strips; the first grating and the second grating are perpendicularly superposed at an interval; a corresponding number of dual-grating superposition regions are formed at the interval superposed position; first voltage is fed into the first grating through a first power line; second voltage is fed into the second grating through a second power line; an electric field in the region covered by the dual-grating superposition regions makes liquid crystals in the electric field be distorted, and light rays are not allowed to pass through the electric field; therefore, a first image and a second image which have vision differences are respectively formed at right and left eyes of a viewer; and after the brain of the viewer receives the first image and the second image, a three-dimensional image can be automatically formed.
Description
technical field [0001] The invention relates to stereoscopic display technology, in particular to a liquid crystal grating unit, a display device and a display method. Background technique [0002] There are many ways to realize 3D display. Light barrier 3D technology is also called parallax barrier or parallax barrier technology, and its principle is similar to polarized 3D. Light barrier 3D products are compatible with existing LCD processes, so they have advantages in yield and cost. At present, the liquid crystal grating 3D display technology generally forms striped electrode strips on the upper and lower substrates of the liquid crystal grating unit. It cannot pass through, so that the liquid crystal grating forms interlaced light and dark stripes. At this time, the left and right eyes of the viewer see the displayed left eye image and right eye image respectively, and the brain synthesizes to form a 3D image. [0003] In the prior art, the full parallax 2D / 3D switcha...
