New description: [New technical field] This creation is about a stereoscopic display device, especially a stereoscopic display device with light weight, high brightness and high resolution. [Prior Art] After years of research, stereoscopic display technology has developed several display modes that enable viewers to produce a stereoscopic vision. The so-called stereoscopic vision mainly applies different images to the left eye and the right eye, so that the brain analyzes and overlaps, and then perceives the layering and depth of the object, thereby producing a three-dimensional sense. Therefore, the stereoscopic display device displays the left-eye signal and the right-eye signal on the left and right eyes of the viewer through a certain technique, so that the viewer feels the image content and has a three-dimensional effect. In general, an autostereoscopic display device uses images such as a lenticular lens, a parallax barrier, or a lens array to isolate images of left and right eyes. Among them, a parallax barrier is a technique employed by many people. In the prior art, the parallax barrier has a fence-like structure, which can separately isolate the information of the left and right eyes, and the parallax barrier can be __ kind of petal, or "liquid crystal panel ^ use liquid crystal panel as parallax, except that 3D can be displayed. In addition to the stereoscopic surface, the 2D/3D scenes can be converted by switching the t source. The figure is a schematic diagram of a stereoscopic display device for making a doping panel as a parallax barrier, and the stereoscopic display device includes an image display element M381074 11, and a parallax barrier 12. The image display element η can display an image information, usually a liquid crystal panel. The parallax barrier 12 has two substrates 121 and 122. Two layers of indium tin oxide (NO) electrodes 123 and 124 are respectively disposed on the two substrates 121 and 122. The electrodes 123 have a gate-like structure, and the electrodes 124 are In the planar structure, liquid crystal molecules are implanted between the electrodes 123 and 124 to form a liquid crystal layer 125. To operate the 3D mode, a driving voltage can be applied to the electrodes 123 and 124, and the parallax barrier 12 forms a bright and alternating barrier structure for the viewer to receive and generate a stereoscopic image. When the 2D mode is to be operated, • no driving voltage is applied to the electrodes 123 and 124, so that no gate structure is generated, and the viewer can obtain a -2D image of the plane. However, since the barrier structure is blocked when the 3D mode is operated The image display element η has an area of at least -half, so there is a disadvantage that the brightness and the resolution are sharply reduced by half. In addition, since such a stereoscopic display is required to increase the structure of a parallax barrier, the overall thickness and cost are also increased. The brightness and volume of the light stand-up device is the current industry
