Embodiment 1

[0046] like Figure 4 and Figure 7 As shown, the display panel 1 is a 5.5-inch, 720p (eg, 1280×720 pixels) liquid crystal panel. The first electrode 24 is placed at an angle of 75° to the left relative to the horizontal direction, the width of the liquid crystal lens unit is equal to 0.256mm, and the cell thickness of the liquid crystal lens 2 is 0.030mm, and the ordinary light refractive index n of the liquid crystal molecule 23 is o is 1.524, extraordinary light refractive index n e is 1.824. Since the display unit 11 of the display panel 1 includes three display subunits 111 , it can be obtained that the width of each display subunit 111 is about 31 μm. The width of the first electrodes 24 is set to be 15 μm, the distance between two adjacent first electrodes 24 is 17 μm, and the second electrodes 25 are surface electrodes.

[0047] Similarly, the voltage applied to the first electrode 24 at the boundary of the liquid crystal lens unit is the largest and greater than t...

Embodiment 2

[0052] like Figure 11 As shown, the display panel 1b is a 5.5-inch liquid crystal panel with a resolution of 2K (eg, 2048×1080 pixels). Each liquid crystal lens unit of the liquid crystal lens is placed obliquely to the right by 75° with respect to the horizontal direction of the display panel 1b, and the width of the liquid crystal lens units, that is, the pitch, is equal to 18 μm. Since the display unit of the display panel 1b includes three display subunits 111b, it can be obtained that the width of each display subunit 111b is about 15 μm. In this way, the width of the first electrodes 24 b is 15 μm, the distance between two adjacent first electrodes 24 b is 15 μm, and the second electrodes are surface electrodes.

[0053] Similarly, the voltage applied to the first electrode 24b at the boundary of the liquid crystal lens unit is the largest and greater than the threshold voltage v of the liquid crystal molecules th , the voltage applied from the corresponding first ele...

Embodiment 3

[0055] like Figure 12 As shown, the display panel 1c is a 28-inch liquid crystal panel with a resolution of 2K (eg, 2048×1080 pixels). The liquid crystal lens units of the liquid crystal lens are placed at an angle of 70° to the left relative to the horizontal direction of the display panel 1c, and the width of the liquid crystal lens units, that is, the pitch, is equal to 33 μm. Since the display unit of the display panel 1c includes three display subunits 111c, it can be obtained that the width of each display subunit 111c is about 57 μm. In this way, the width of the two first electrodes 24c located at the boundary of the liquid crystal lens unit is 15 μm, the width of other first electrodes 24c in the middle of the first electrodes 24c on both sides of the liquid crystal lens unit is 20 μm, and the adjacent two first electrodes 24c The distance between them is 30 μm, and the second electrode is a surface electrode.

[0056] Similarly, the voltage applied to the first el...

Abstract

The present invention is applicable to the technical field of stereoscopic display, and provides a stereoscopic display device. The stereoscopic display device includes a liquid crystal lens and a display panel. The display panel includes M×N display units arranged in an array, and the liquid crystal lens includes a plurality of first electrodes. The first electrodes are spaced apart from each other, and the extension direction of the first electrodes is different from the arrangement direction of the display units. When the liquid crystal lens is used for 3D display, a liquid crystal lens unit is formed between the first substrate and the second substrate, and each liquid crystal lens unit Corresponding to n first electrodes arranged continuously, n≥4, the first driving voltage corresponding to each first electrode is arranged symmetrically with the center line of the liquid crystal lens unit, and gradually decreases from the boundary to the center of the liquid crystal lens unit. Improve the deflection degree of the liquid crystal molecules near the first electrode, present a smoother state in terms of phase retardation, reduce the phase difference at the junction of two adjacent liquid crystal lens units, weaken the large crosstalk brought here, and improve the stereoscopic display. effect and viewing comfort.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and in particular relates to a stereoscopic display device. Background technique [0002] In recent years, three-dimensional display technology has developed rapidly and has become a research hotspot. At present, stereoscopic display technology has important applications in fields such as medical treatment, advertising, military affairs, exhibitions, and games. The early stereoscopic display technology mainly used stereoscopic glasses to watch the stereoscopic images, but the current mainstream product is a naked-eye stereoscopic display device based on binocular parallax. At least two parallax images are respectively provided to the left and right eyes of the viewer, so that the viewer sees 3D images. [0003] figure 1 A structural schematic diagram of a stereoscopic display device provided in the prior art. The stereoscopic display device includes a display panel 1' and a liquid...
