[0051] Such as image 3 As shown, this embodiment provides a liquid crystal antenna panel, including the liquid crystal antenna substrate provided in embodiment 1 and the liquid crystal antenna cover plate 6 arranged in a box opposite to the liquid crystal antenna substrate, and the two are sealed by a sealant 7 .

[0052] Wherein, the liquid crystal antenna substrate may be an array substrate or a support layer substrate, and correspondingly, the liquid crystal antenna cover plate may be a support layer substrate or an array substrate. The following description will be made by taking the liquid crystal antenna substrate as the array substrate and the liquid crystal antenna cover plate 6 as the support layer substrate as an example.

[0053] Specifically, such as image 3 As shown, the liquid crystal antenna cover 6 is coated with a sealant 7 at the sealing area A, and the sealant 7 is in contact with the upper surface of the barrier structure 2 . Compared with the prior art...

Embodiment 3

[0055] This embodiment provides a method for preparing a liquid crystal antenna substrate, which is used to prepare the liquid crystal antenna substrate provided in Embodiment 1 or Embodiment 2. Wherein, the liquid crystal antenna substrate may be an array substrate or a supporting layer substrate, and the following description will be made by taking that the liquid crystal antenna substrate may be an array substrate as an example.

[0056] The preparation method of the liquid crystal antenna substrate includes: forming a barrier structure in the sealing area of ​​the substrate through a patterning process, and the thickness of the barrier structure is greater than 50 microns.

[0057] Preferably, the preparation method further includes: forming an auxiliary structure on the side of the barrier structure close to the liquid crystal region through a patterning process, and the auxiliary structure is in contact with the barrier structure; specifically, the auxiliary structure is ...

Abstract

The invention provides a liquid crystal antenna substrate and a preparation method thereof, and a liquid crystal antenna panel and a preparation method thereof, belonging to the technical field of liquid crystal antennas and aiming to solve the problem that a liquid crystal can be leaked off as frame sealing glue can be impacted by the liquid crystal in the conventional liquid crystal antenna preparation process. The liquid crystal antenna substrate provided by the invention is divided into a liquid crystal zone and a sealing zone and comprises a substrate, wherein a baffle structure is arranged on the substrate and in a position corresponding to the sealing zone; and the thickness of the baffle structure is greater than 50 micrometers.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal antennas, and in particular relates to a liquid crystal antenna substrate and a preparation method thereof, a liquid crystal antenna panel and a preparation method thereof. Background technique [0002] Smart antenna refers to an adaptive antenna array, which can automatically adjust the weighted vector of each antenna element to a signal in a certain direction according to a specific receiving criterion, form an array pattern and beam, and align the main lobe direction of the pattern with the useful signal , and at the same time align the direction of the low side lobe or null to the direction of the interference signal, so as to achieve the purpose of "spatial filtering". Compared with the traditional metal antenna, the liquid antenna is an antenna composed of liquid crystal instead of the technical material used in the ordinary antenna radiation unit. It can repair itself after damage an...
