Problems solved by technology

The use of two panels increases the complexity of the display device, resulting in a bulky display device that is inconvenient to carry
At the same time, since there may be optical or electrical interference between the lens panel and the touch panel, this will greatly affect the display effect and reduce the user experience.

Embodiment Construction

[0059] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0060] The touch-type liquid crystal lens panel provided by the present invention includes two electrode structures arranged at intervals and a liquid crystal layer. Wherein, the liquid crystal layer is arranged between the two electrode structures, and the liquid crystal layer includes a plurality of liquid crystal molecules.

[0061] In the specific implementation process, through the configuration, the electric field between the two electrode structures, the electric field makes the liquid crystal molecules in a predetermined alignment state, changes the propagation direction of the light, and makes the liquid crystal layer have a lens effect. Furthermore, the electrode structure also constitutes a variable capacitor, forming a touch driving point, and the capacitive touch positioning function is realized by applying a driving voltage on one electr...

Abstract

The invention discloses a touch-type liquid crystal lens panel, which comprises a first electrode structure, a second electrode structure and a liquid crystal layer, wherein the second electrode structure is formed opposite to the first electrode structure; the liquid crystal layer is formed between the first electrode structure and the second electrode structure; the first electrode structure, the liquid crystal layer and the second electrode structure are configured into a liquid crystal lens with a function of changing the light ray transmitting direction; and the first electrode structure, the liquid crystal layer and the second electrode structure are further configured into a touch position signal for detecting at least one touch occurring on the touch-type liquid crystal lens paneland representing the occurrence of the touch on the touch-type liquid crystal lens panel. The touch-type liquid crystal lens panel has the functions of the liquid crystal lens and multi-point touch and a simple structure. The invention further provides a three-dimensional display device and a computer system applying the touch-type liquid crystal lens panel.

Description

【Technical field】 [0001] The invention belongs to the field of stereoscopic display, and in particular relates to a touch-type liquid crystal lens and a driving method thereof, and also relates to a stereoscopic display device using the touch-type liquid crystal lens and a computer system using the stereoscopic display device. 【Background technique】 [0002] With the continuous development of liquid crystal technology, liquid crystal materials are widely used in various fields. [0003] For example, a traditional optical zoom lens group requires at least two or more lenses to move in cooperation with each other to achieve the effect of zooming. In practical application, such an optical zoom lens group is often thick and bulky, which brings great inconvenience to users. [0004] LC Lens (Liquid Crystal Lens, liquid crystal lens) is an optical component that uses the birefringence characteristics of liquid crystal molecules and the arrangement characteristics that change with...
