Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If spherical spacers are used, then the manufacturing process is simple, but the distribution density is uneven affecting display quality
Solution Approach 1:
The single spherical spacer is segmented into multiple protrusions (first spacers on array substrate, second spacers on CF substrate) that form a cross-shaped configuration. This segmentation allows each protrusion to contribute to the overall spacing function while improving distribution control through structured placement patterns.
Solution Approach 2:
The cross-shaped spacer structure introduces asymmetry in the spacer configuration, with protrusions extending in specific directions (e.g., horizontal and vertical orientations). This asymmetric design enables better control over spacer distribution and prevents the uniformity issues associated with spherical spacers while maintaining manufacturing feasibility.
2Device complexity
If pillar-like spacers are used, then the spacer structure is simple, but the spacers shift under external force causing permanent light leakage
Solution Approach 1:
The invention merges the functions of multiple spacers into a unified cross-shaped spacer structure. The first spacers on the array substrate and second spacers on the CF substrate work together as an integrated system, where the相互配合 of multiple protrusions provides mutual support and prevents individual spacer displacement that would occur with simple pillar-like spacers.
Solution Approach 2:
The cross-shaped spacer structure is pre-configured with protrusions extending in multiple directions before assembly. This preliminary structural arrangement ensures that when the array substrate and CF substrate are combined, the spacers are already positioned to resist external forces from multiple directions, preventing displacement before it can occur during operation.
3Ease of manufacture
If single-sided spacers are used, then the manufacturing process is simple, but the contact area is insufficient under external impact
Solution Approach 1:
The invention transitions from single-sided spacers to a dual-sided cross-shaped configuration. By adding spacers on both the array substrate side and CF substrate side, and extending protrusions in horizontal and vertical dimensions, the contact area is significantly increased while maintaining manufacturing simplicity through a systematic design approach.

AI summary
A liquid crystal panel and a cross-shaped spacer structure thereof are disclosed. The liquid crystal panel includes an array substrate, a color filter substrate, and a cross-shaped spacer structure sandwiched between the array substrate and the color filter substrate. The cross-shaped spacer structure includes a plurality of H-shaped first spacers disposed on the upper surface of the array substrate and a plurality of strip-like second spacers disposed on the lower surface of the color filter substrate. The end surface of the crossbar of each one of the H-shaped first spacers and the end surface of each one of the strip-like second spacers are abutted against each other in a cross manner. Thus, when the liquid crystal panel is impacted by external force, the H-shaped first spacers and the strip-like second spacers can keep a tight abutment therebetween, so as to ensure the display quality of the liquid crystal panel.
