Problems solved by technology
The common way to achieve liquid crystal alignment is to form an ITO film on the top layer of the substrate that confines liquid crystal molecules by sputtering, and form a polyimide layer, and then rub the polyimide layer with a rubbing cloth to form a liquid crystal. Alignment layer, but this method is not only costly and time-consuming, but also has the problem of light attenuation because the light must pass through the ITO film
[0003] In addition, the liquid crystal alignment layer formed by rubbing with a rubbing cloth often causes product defects such as Zara light leakage and rubbing marks Mura due to problems such as the amount of rubbing cloth press-in

Embodiment Construction
[0025] It will be understood that when an element or layer is referred to as being "on" or "connected to" another element or layer, it can be directly on, directly connected to, or directly on the other element or layer. Either directly bonded to another element or layer, or intervening elements or layers may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element or layer, there are no intervening elements or layers present. Like reference numerals refer to like elements throughout. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0026] For ease of description, spatially relative terms such as "below," "above," "on," "beneath," etc. may be used herein to describe one element or feature as shown in the figures in relation to other elements or features. Relationship. It will be understood that the spatially relative terms are intended to...

The invention provides a liquid crystal panel, a method for manufacturing the liquid crystal panel and a driving method for the liquid crystal panel. The liquid crystal panel comprises an upper panel, a lower panel and a liquid crystal layer, wherein the liquid crystal layer is formed between the upper panel and the lower panel; the upper panel comprises an upper base plate, a polycrystalline silicon layer, a piezoelectric material layer, a metal pattern and an organic material layer; the polycrystalline silicon layer is formed on the upper base plate; the piezoelectric material layer, the metal pattern and the organic material layer are formed on the polycrystalline silicon layer of the upper base plate in turn; the organic material layer is covered with the metal pattern; the lower panel comprises a lower base plate, a polycrystalline silicon layer, a piezoelectric material layer, a metal pattern and an organic material layer; the polycrystalline silicon layer is formed on the lower base plate; the piezoelectric material layer, the metal pattern and the organic material layer are formed on the polycrystalline silicon layer of the lower base plate in turn; the organic material layer is coated with the metal pattern; two bus bars in the shape of finger crossing are arranged on the metal pattern, so as to form an interdigital transducer.
Description
technical field [0001] The present disclosure relates to the field of liquid crystal display, and more particularly, to a liquid crystal panel, a method for manufacturing a liquid crystal panel, and a driving method for a liquid crystal panel. Background technique [0002] In a liquid crystal display, the liquid crystal molecules are usually controlled by an external electric field or magnetic field, so as to realize the alignment of the liquid crystal molecules. The common way to achieve liquid crystal alignment is to form an ITO film on the top layer of the substrate that confines liquid crystal molecules by sputtering, and form a polyimide layer, and then rub the polyimide layer with a rubbing cloth to form a liquid crystal. Alignment layer, but this method is not only costly and time-consuming, but also has the problem of light attenuation because the light must pass through the ITO film. [0003] In addition, the liquid crystal alignment layer formed by rubbing with a ...
