Solution Overview

Problem

Assembly errors during the construction of liquid crystal modules, particularly between the liquid crystal glass and the backlight source, lead to inconsistent black matrix widths and affected display areas in liquid crystal displays.

Innovation Solution

A connecting assembly with adjustable engaging locations and U-shaped holes allows for precise alignment of the front frame and liquid crystal glass, ensuring consistent display areas by enabling adjustments in the relative positions of the connecting assembly, plastic frame, and back plate, thereby maintaining the integrity of the black matrix.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the liquid crystal glass is assembled with the plastic frame and front frame using fixed engagement locations, then the assembly process is simple, but assembly errors occur causing inconsistent black matrix widths and display area discrepancies

Engineering Contradiction:
Improveblack matrix width consistencyVSAvoidconnecting assembly structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The connecting assembly incorporates adjustable engagement locations that allow dynamic positioning during assembly. The U-shaped holes in the connecting assembly can engage with different positions on the vertical plate, enabling adjustment of the relative location between the liquid crystal glass and front frame to compensate for assembly errors and maintain consistent black matrix widths.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The design changes the engagement parameter from fixed to adjustable. By providing U-shaped holes at different positions on the connecting assembly that can engage with corresponding positions on the vertical plate, the system allows variation in engagement location to optimize the relative positioning of components, thereby ensuring consistent display areas.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the engaging location between connecting assembly and plastic frame is fixed, then the assembly process is straightforward, but the display area is affected due to displacement errors

Engineering Contradiction:
Improvedisplay area consistencyVSAvoidassembly process simplicity
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The connecting assembly features adjustable engagement locations with U-shaped holes that can be positioned at different heights. This allows the assembly process to accommodate displacement errors by adjusting the engagement position, thereby maintaining consistent display areas while keeping the assembly process relatively simple through straightforward bolt engagement.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the front frame is assembled with fixed positioning, then the assembly is quick, but the relative location of front frame and liquid crystal glass cannot be adjusted to correct assembly errors

Engineering Contradiction:
Improveadjustability of relative locationsVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The connecting assembly incorporates adjustable engagement locations with U-shaped holes that can be positioned at different heights. This allows the relative location between the front frame and liquid crystal glass to be adjusted during assembly by selecting different engagement positions, providing adaptability to correct assembly errors while minimizing additional assembly time through straightforward adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

AI summary

A liquid crystal module is disclosed. The liquid crystal module includes a back plate having a vertical plate, a plastic frame arranged on the vertical plate for supporting the liquid crystal glass, a connecting assembly and a front frame. The connecting assembly is arranged above the plastic frame. An engaging location of the connecting assembly and the plastic frame is adjustable. A lateral side of the connecting assembly abuts against an edge of the liquid crystal glass. The front frame arranged above the connecting assembly is fixed with the connecting assembly. The front frame covers a rim of the liquid crystal glass. The relative location of the front frame and the liquid crystal glass can be easily adjusted via the connecting assembly. In addition, the displacement of the display area resulting from assembly errors is avoided. As such, the display area and the exposed black matrix remain consistent.
