Liquid Crystal Display Cooling via Frame Void and Sealant Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display apparatuses face challenges in effectively suppressing temperature increases in liquid crystal panels, which can hinder high luminance and definition, and previous cooling techniques compromise sealing properties and require increased structural size.
Innovation Solution
A liquid crystal display apparatus design that includes a liquid crystal panel, a panel housing, a first transparent member, and a frame member forming a void between the panel and the transparent member for coolant flow, with entrance and exit flow paths in the panel housing and introduction and discharge holes in the frame member, allowing for efficient coolant circulation without relying on additional flow path members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a through hole is formed on the sealant to allow coolant flow, then liquid cooling of the liquid crystal panel is achieved, but the sealing property is compromised and the structural size must be increased
Solution Approach 1:
The sealant is segmented into a first sealant layer and a second sealant layer positioned at different heights. The first sealant layer forms a first void space for coolant flow, while the second sealant layer provides sealing. This segmentation allows the coolant flow function and sealing function to be separated, resolving the contradiction between achieving liquid cooling and maintaining sealing property.
Solution Approach 2:
The patent introduces a vertical dimension by positioning the first and second sealant layers at different heights (first height and second height). The first void space is formed between these layers, creating a three-dimensional structure that allows coolant flow while maintaining sealing integrity through the layered configuration.
2Temperature
If a through hole is formed on the sealant to allow coolant flow, then liquid cooling of the liquid crystal panel is achieved, but the structural size increases making it impossible to incorporate into existing display apparatuses
Solution Approach 1:
The first and second sealant layers are merged into a single integrated sealant structure that simultaneously provides both sealing and coolant flow paths. The first void space is formed within the sealant itself rather than as a separate component, merging the sealing function and cooling function into one unified structure that does not increase the overall device size.
Solution Approach 2:
The sealant structure is designed to perform multiple functions: it provides sealing between the liquid crystal panel and the housing, and simultaneously forms void spaces for coolant flow. This multi-functionality eliminates the need for separate cooling components, allowing the system to be incorporated into existing display apparatuses without increasing structural size.

AI summary
A liquid crystal display apparatus effectively suppresses a temperature increase in a liquid crystal panel, and includes: a liquid crystal panel; a panel housing configured to accommodate the liquid crystal panel; a first transparent member disposed on a front face side of the liquid crystal panel; and a frame member configured to hold the first transparent member and to be attachable to the panel housing, the frame member defining an interval between the liquid crystal panel and the first transparent member, and forming, between the liquid crystal panel and the first transparent member, a void that allows a coolant to flow along a front face of the liquid crystal panel. The panel housing includes an entrance flow path of the coolant formed at a first part of the panel housing, and an exit flow path of the coolant formed at a second part of the panel housing excluding the first part, and the frame member includes an introduction hole that has one end coupled to the entrance flow path and causes the entrance flow path to be communicated with the void, and a discharge hole that has one end coupled to the exit flow path and causes the exit flow path to be communicated with the void.
