Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the height difference between the main post spacer and the auxiliary post spacer is increased, then the lower limit of the liquid crystal margin is reduced, but the compression resistivity of the panel is weakened
Solution Approach 1:
The invention divides the post spacer system into two distinct functional components: main post spacers that provide compression resistance, and auxiliary post spacers that define the lower limit of liquid crystal margin. This segmentation allows each component to be optimized independently for its specific function, resolving the contradiction between compression resistivity and liquid crystal margin.
Solution Approach 2:
The invention applies different properties to different parts of the post spacer system. The main post spacers are designed with specific height and compression characteristics to provide structural support, while the auxiliary post spacers are designed with different height characteristics to control liquid crystal filling margin. This local differentiation allows simultaneous optimization of both compression resistivity and liquid crystal margin.
2Quantity of substance
If the amount of compression of the main post spacer is increased, then the upper limit of the liquid crystal margin is increased, but the process fluctuation in mass production is restricted
Solution Approach 1:
By segmenting the post spacer functions, the invention allows the main post spacer compression to be optimized for maximizing liquid crystal margin upper limit, while the auxiliary post spacer handles the lower limit control. This eliminates the need to restrict process fluctuation to maintain compression resistivity, thereby improving productivity.
Solution Approach 2:
The invention introduces flexibility in the system by allowing the main post spacer to be compressed within an optimized range to maximize liquid crystal margin, while the auxiliary post spacer provides a stable reference for the lower limit. This dynamic optimization enables increased upper limit without negatively impacting mass production stability.

AI summary
The present disclosure relates to the technical field of liquid crystal display. A liquid crystal panel and a display panel are provided. A main post spacer of the liquid crystal panel is arranged on a first substrate. A stopping structure used to stop the main post spacer from moving in a direction away from a second substrate is arranged on the second substrate. Hence, even if lots of liquid crystals are filled, the main post spacer and the second substrate may be kept in a seamless state due to the stopping structure.
