Display Device Light Source Segmentation Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices, the placement of the light source part and electronic components in the lower portion leads to increased thickness and potential high temperatures due to heat emission, as the light source and components are often positioned close to each other.
Innovation Solution
The light source part and substrate are positioned at different locations, with the light source placed in the upper portion and electronic components on the rear surface, reducing the overall thickness and preventing high temperatures by separating heat-emitting components.

Engineering Contradiction Analysis
1Device complexity
If the light source part and electronic components are positioned in the lower portion of the display device, then the device structure is simplified, but the overall thickness increases and temperature in the lower portion becomes high
Solution Approach 1:
The patent divides the lower portion space into two separate regions: one for the light source part and another for electronic components. This segmentation allows each component to be positioned independently, reducing the overall thickness requirement while maintaining structural simplicity. The light source part is positioned at a first distance from the display part, and electronic components are positioned at a second distance, creating distinct functional zones that optimize both thickness and heat management.
2Device complexity
If the light source part and electronic components are positioned in the lower portion of the display device, then the device structure is simplified, but the temperature in the lower portion becomes high due to heat emission
Solution Approach 1:
The patent segments the lower portion into distinct regions for light source and electronic components, positioned at different distances from the display part. This spatial segmentation separates heat-emitting components, preventing heat concentration in a single location and thereby reducing the overall temperature in the lower portion while maintaining structural simplicity.
3Device complexity
If the light source part is positioned close to electronic components, then the device structure is compact, but heat dissipation becomes inefficient
Solution Approach 1:
The patent applies segmentation by positioning the light source part and electronic components at different distances from the display part, creating spatial separation between heat-emitting components. This segmentation improves heat dissipation efficiency by preventing heat accumulation in a concentrated area, while the overall device structure remains compact through optimized spatial arrangement.

AI summary
A display device of which an entire thickness in front and rear directions can be reduced and in which temperature of a lower portion can be prevented from being high is provided. A television device (display device) (100) includes a light source part (2), an optical sheet (5), and a rear frame (6). The light source part (2) is disposed in the upper portion of the television device (television device) (100) and a hollow light-guiding region (7) is provided between the reflection sheet (4) and the optical sheet (5). In the reflection sheet (4), a distance to the optical sheet (5) is less in the lower portion than in the upper portion.
