Problems solved by technology

Only when the user faces the stereoscopic display device and his eyes are focused on the center of the screen, can he see a better display effect, but when the user observes the left and right sides of the screen, if the stereoscopic image has a large parallax, ghosting will also occur, affecting the display Effect

[0090] Please refer to Figure 11 , this embodiment provides a stereoscopic display unit 100, which is applied to a stereoscopic display system 1000. The biggest difference between the stereoscopic display unit 100 in this embodiment and the first embodiment of the present invention is that the second electrode 140 is placed in the first The direction is divided into a first area, a second area and a third area, and a plurality of strip-shaped electrodes located in the first area are symmetrically distributed with the center line of the first area as the axis, and located on the center line of the first area The strip electrodes at symmetrical positions on both sides are supplied with the same driving voltage by the voltage driving unit 400 . Particularly, in this embodiment, in each microlens unit 150 located in the first region, the strip-shaped electrodes distributed symmetrically with the center line of each microlens unit 150 are supplied by the voltage driving unit 400 ...

Abstract

The invention provides a three-dimensional display unit, a three-dimensional display system and a driving voltage adjusting method, and belongs to the field of three-dimensional display. The three-dimensional display unit comprises a first substrate, a second substrate, a first electrode, a second electrode and a liquid crystal material, wherein the first substrate and the second substrate are oppositely arranged; the first electrode is arranged on the side, near the second substrate, of the first substrate; the second electrode is arranged on the side, near the first substrate, of the second substrate; the liquid crystal material is arranged between the first electrode and the second electrode; the second electrode comprises a plurality of mutually-independent bar-shaped electrodes which are arranged in parallel in a first direction and stretch in a second direction; an independent electrode connecting line supplies driving voltage for each bar-shaped electrode; the first electrode is connected with a reference voltage terminal. Compared with the prior art, the three-dimensional display unit has the advantage as follows: the refractive index distribution of the liquid crystal material can be changed by changing the driving voltage of the bar-shaped electrodes so as to change the surface type of a three-dimensional display.

Description

technical field [0001] The present invention relates to the field of stereoscopic display, in particular to a stereoscopic display unit, system and driving voltage adjustment method. Background technique [0002] The existing three-dimensional display unit is mostly a liquid crystal lens, which is driven by a fixed voltage. When the liquid crystal lens performs three-dimensional display, the refractive index distribution of the liquid crystal molecules in the liquid crystal material will not change, so that the three-dimensional display surface type is fixed. [0003] In actual use, when the user deviates from the normal viewing position and is located on the left or right side of the screen, the light emitted from the right or left side of the screen and entering the human eye deviates the most from the main axis of the lens, and the stereoscopic image seen by the human eye will produce Larger crosstalk. Only when the user faces the stereoscopic display device and his eyes...
