[0037] Figure 1A and Figure 1B It is a schematic diagram of the stereoscopic display device according to the first embodiment of the present invention. especially, Figure 1A shows the state that the stereoscopic display device is in the three-dimensional long viewing distance mode, and Figure 1B A state in which the stereoscopic display device is in the three-dimensional short-sight mode is shown. Please refer to Figure 1A and Figure 1B , the stereoscopic display device 1000 of this embodiment includes a display panel 100 and an adjustable grating 200 . The display panel 100 is suitable for providing an image M. Referring to FIG. The image M includes a left-eye image ML and a right-eye image MR. The adjustable grating 200 is located on the transmission path of the image M. In this embodiment, the display panel 100 may be a non-self-luminous display, such as a liquid crystal display panel. However, the present invention is not limited thereto. In other embodiments, ...

[0050] The stereoscopic display device of this embodiment is similar to the stereoscopic display device of the first embodiment, so the same components are denoted by the same reference numerals. The main difference between the two is that the structure of the adjustable grating is different. image 3 It is a three-dimensional schematic diagram of the adjustable grating according to the second embodiment of the present invention. The adjustable grating 200A of this embodiment is similar to the adjustable grating 200 of the first embodiment and the adjustable grating 200 of the first embodiment. The tunable grating 200A of this embodiment is different from the tunable grating 200 of the first embodiment in that: the structure of the first substrate 210A of this embodiment is different from that of the first substrate 210 of the first embodiment. The difference will be described below, and the similarities between the two will not be repeated.

[0060] The stereoscopic display device of this embodiment is similar to the stereoscopic display device of the second embodiment, so the same components are denoted by the same reference numerals. The main difference between the two is that the structure of the adjustable grating is different. Figure 6 It is a three-dimensional schematic diagram of the adjustable grating according to the third embodiment of the present invention. Figure 7 for correspondence Figure 6 A schematic cross-sectional view of the adjustable grating indicated by the middle segment CC'. Please refer to Figure 6 and Figure 7 , the adjustable grating 200B of this embodiment is similar to the adjustable grating 200A of the second embodiment. The difference between the adjustable grating 200B of this embodiment and the adjustable grating 200A of the second embodiment is that in this embodiment, the relative positions of the first substrate 210A and the second substrate 220 are different from those ...

Abstract

The invention relates to a three-dimensional display device which comprises a display panel and an adjustable grating. The display panel is applicable in providing an image. The adjustable grating is arranged on the transmission path of the image. The adjustable grating comprises a first substrate, a second substrate which is over against the first substrate and a display medium which is arranged between the first and the second substrates. The second substrate comprises a second substrate bottom, and a plurality of first electrodes and a plurality of second electrodes which are arranged on the second substrate bottom. The first electrodes are lined with equal spacing. The second electrodes and the first electrodes are lined alternatively. The second electrodes are also lined with equal spacing. The first spacing is left between any two adjacent first electrodes. The second spacing is left between any two adjacent second electrodes. The first spacing is more than the second spacing.

Description

technical field [0001] The invention relates to a stereoscopic display device, and in particular to a stereoscopic display device capable of switching the best viewing distance. Background technique [0002] As far as current display technologies are concerned, stereoscopic display technologies can be broadly classified into stereoscopic, in which viewers need to wear specially designed glasses, and auto-stereoscopic, in which viewers directly watch with naked eyes. Among them, the glasses-wearing stereoscopic display technology has developed maturely and is widely used in some special purposes such as military simulation or large-scale entertainment. However, the glasses-wearing stereoscopic display technology is not easy to popularize because of its poor convenience and comfort. Therefore, the naked-eye stereoscopic display technology has gradually developed and become a new trend. [0003] A known autostereoscopic display includes a display panel for providing images an...
