Solution Overview
Problem
Existing liquid crystal panel fabrication methods face challenges in maintaining uniform cell thickness and picture quality due to excessive liquid crystal, leading to non-uniformity and defects.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If liquid crystal is dropped onto the array substrate using the one-drop-filling process, then the liquid crystal panel display region is filled with liquid crystal, but excessive liquid crystal causes non-uniformity of picture and other defects
Solution Approach 1:
The invention divides the space between substrates into two distinct regions: a liquid crystal buffer region (vacuum chamber) and a liquid crystal panel display region. This segmentation allows excess liquid crystal to be contained in the buffer region while maintaining precise control over the display region, preventing non-uniformity and defects caused by excessive liquid crystal.
2Strength
If a sealant is applied to bond the array substrate and color filter substrate, then the substrates are attached, but maintaining strict cell thickness requirements becomes difficult with excessive liquid crystal
Solution Approach 1:
The liquid crystal buffer region acts as an intermediary space between the sealed display region and the external environment. It absorbs excess liquid crystal and provides a buffer zone that maintains stable cell thickness in the display region, allowing the sealant to effectively bond substrates without compromising thickness precision.
3Reliability
If the liquid crystal panel is sealed to prevent leakage, then substrate bonding is achieved, but no provision is made for handling excessive liquid crystal
Solution Approach 1:
The invention embeds a liquid crystal buffer region (vacuum chamber) within the sealed space between substrates. This nested structure allows the system to maintain seal integrity while providing an internal reservoir for excess liquid crystal, avoiding the need for complex external control mechanisms.

AI summary
Embodiments of the present invention relate to a liquid crystal panel and a fabricating method thereof and a display. The liquid crystal panel comprises: an array substrate and a color filter substrate bonded by a first sealant, with a region surrounded by the first sealant between the array substrate and the color filter substrate forming a liquid crystal panel display region filled with liquid crystal. In addition, the liquid crystal panel further comprises: a liquid crystal buffer region, located at the outer side of the first sealant; a liquid crystal channel, through which the liquid crystal buffer region and the liquid crystal panel display region are connected; and a covering layer, covering at least a position where the liquid crystal channel connects with the liquid crystal panel display region.
