Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side-entry-type liquid crystal displays suffer from poor heat radiation, leading to increased temperatures, shortened service life of light bars, and higher usage costs due to the arrangement of circuit boards and wires, which obstruct heat dissipation and require frequent replacements.
Innovation Solution
Integrating heat radiating structures on the mounting frame with outlets in the outer frame to directly dissipate heat outside, improving the overall heat radiation effect without affecting the display's thickness, and using heat radiating pipelines and fins to enhance convection, while positioning control components to avoid blocking heat transfer paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the circuit board and wire are arranged by bypassing the side of the mounting frame from the front side, then the control component can be attached to the rear side, but the heat radiating effect of the display becomes poor
Solution Approach 1:
The patent introduces heat radiating pipelines that extend from the mounting frame to the outer frame, creating a new spatial dimension for heat dissipation. This three-dimensional heat radiation path allows heat to escape laterally through the side surfaces, bypassing the blocking effect of the wire coating the mounting frame.
2Strength
If the outer frame covers the display module for protection, then the structural integrity is improved, but the heat radiating effect becomes poor particularly under high brightness conditions
Solution Approach 1:
The outer frame is designed with localized heat radiating outlets at specific positions (front surface, rear surface, and side surfaces) that allow heat to escape while maintaining the overall protective enclosure. This localized modification preserves the protective function while creating thermal ventilation channels.
Solution Approach 2:
The heat radiating pipelines act as intermediary structures that conduct heat from the mounting frame (where the light bar generates heat) to the outer frame (which provides protection). These pipelines serve as thermal conduits that connect the heat source to the external environment while maintaining the protective enclosure.
3Illumination intensity
If high brightness is maintained for display performance, then the illumination intensity is improved, but the temperature of the overall display becomes overhigh and service life of light bar is shortened
Solution Approach 1:
The patent converts the harmful heat generated by high-brightness operation into a manageable thermal flow by designing dedicated heat radiating pipelines. The heat that would otherwise damage the light bar is redirected through controlled pathways to external outlets, transforming a harmful byproduct into a directed thermal exhaust that protects system reliability.
