Problems solved by technology

[0004] like image 3 As shown, when the stereoscopic display device is used for 2D display, the liquid crystal lens 1' is powered off. At this time, no electric field is generated between the first substrate 11' and the second substrate 12', and the polarization emitted by the display panel 2' When the light passes through the spacer 14', due to the large difference in refractive index between the spacer 14' and the liquid crystal molecules 13', the light is refracted at the spacer 14', so that when the human eye watches the three-dimensional display device, the spacer 14 'There are bright spots, which affect the viewer's viewing effect and viewing comfort
[0005] The prior art also discloses a stereoscopic display device, including a display panel and a liquid crystal lens grating, the display panel includes a plurality of pixel units and a black matrix arranged between the plurality of pixel units, the liquid crystal lens grating includes spacers, and the spacers The position corresponds to the position of the black matrix in the display panel. Setting the black matrix in the display panel not only affects the display effect of the display panel, but also the black matrix cannot completely cover the gaps, resulting in bright spots in the gaps when viewed by human eyes.

Embodiment approach 2

[0064] Such as Figure 9 As shown, the structure of the stereoscopic display device provided in this embodiment is basically the same as that of the stereoscopic display device provided in Embodiment 1. The difference is that the liquid crystal lens 1a also includes a third electrode 18a, and the third electrode 18a is arranged on each of the first electrodes 15a. An insulating layer (not shown in the figure) is provided between the first substrate 11a and between the third electrode 18a and the first electrodes 15a, and each first electrode 15a is provided on the insulating layer. When the stereoscopic display device is used for 2D display, such as Figure 6 As shown, the voltage module 4 provides the third voltage to each first electrode 15a through the driving circuit 3, provides the fourth voltage to each second electrode 16a, and provides the fifth voltage to the third electrode 18a, the difference between the fourth voltage and the fifth voltage The difference between i...

Embodiment approach 3

[0069] Such as Figure 10 to Figure 12 As shown, the structure of the stereoscopic display device provided in this embodiment is substantially the same as that of the stereoscopic display device provided in Embodiment 1. The alignment direction of the liquid crystal layer 10b is the horizontal direction, and the horizontal direction mentioned here is the vector direction perpendicular to the direction of gravity of the earth. . The difference is that the second electrodes 16b are arranged at intervals, and the angle between the extension direction of the second electrodes 16b and the alignment direction of the liquid crystal layer 10b is an acute angle.

[0070] Such as Figure 10 and Figure 11 As shown, when the stereoscopic display device is used for 2D display, the deflection voltage generates a transverse electric field between the first substrate 11b and the second substrate 12b, and the transverse electric field drives the liquid crystal molecules 13b in the liquid cr...

Abstract

The invention belongs to the technical field of three-dimensional display and provides a three-dimensional display device. The three-dimensional display device comprises a display panel, a liquid crystal lens, a drive circuit and a voltage module, wherein the liquid crystal lens is located on the display side of the display panel; the voltage module is used for supplying initial voltage to the drive circuit; when the three-dimensional display device is used for 3D display, multiple groups of drive voltage required by working of the liquid crystal lens are output after the initial voltage is processed by the drive circuit; when the three-dimensional display device is used for 2D display, deflection voltage is output after each group of drive voltage is processed by the drive circuit; the deflection voltage is higher than threshold voltage of liquid crystal molecules and is lower than or equal to the initial voltage, the liquid crystal molecules in the liquid crystal layer deflect under the action of the deflection voltage, a refractive index difference between each liquid crystal molecule and a photo spacer is reduced, and the influence of the photo spacer on the emergent light of the display panel is eliminated accordingly. Compared with the prior art, the three-dimensional display device has the advantage that the viewing effect and the viewing comfort are improved when the three-dimensional display device is in the 2D display state.

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] With the development of stereoscopic display technology, people require stereoscopic display devices not only to display stereoscopic images, but also to display 2D images according to the needs of viewers, such as displaying text or pictures. Such as figure 1 As shown, the existing stereoscopic display device includes a display panel 2' and a liquid crystal lens 1' disposed on the light-emitting side of the display panel 2'. The display panel 2' provides a left view and a right view with image differences. Through the light splitting effect of the liquid crystal lens 1', the left view enters the viewer's left eye, and the right view enters the viewer's right eye. The viewer's brain based on the perception The image difference forms a stereoscopic image. [0003] Such as figure 1 and figur...
