Infrared Sensor Nesting in Display Front Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices interfere with user immersion due to the external positioning of infrared sensors, which detract from the neat appearance of the display screen.
Innovation Solution
Incorporating an infrared sensor within the display device by designing a mounting system that includes a front cover, guide panel, and sliding groove to securely position the sensor internally, allowing it to be in contact with the front cover and maintain a neat appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the infrared sensor is positioned outside the display device, then the sensor can be easily accessed and installed, but the appearance of the display device becomes less neat and user immersion is interfered with
Solution Approach 1:
The infrared sensor is nested within the display device by inserting it into a mounting hole formed in the front cover. The sensor is positioned between the front cover and guide panel, with the infrared lens exposed through a lens hole in the front cover, creating a nested configuration that maintains neat appearance while accommodating the sensor internally
Solution Approach 2:
The mounting hole is designed to extend in the thickness direction of the display device, allowing the infrared sensor to be positioned internally along the depth dimension. This dimensional approach enables the sensor to be hidden from front view while maintaining functional exposure through the lens hole
2Ease of manufacture
If the mounting hole width in thickness direction is greater than the sensor width, then the sensor can be easily inserted and positioned, but the structural precision and stability are reduced
Solution Approach 1:
The mounting hole is designed with different width characteristics in different directions: wider in the thickness direction to facilitate sensor insertion, and equal to or slightly larger than the sensor width in the horizontal direction to ensure stable positioning. This local quality differentiation optimizes both insertion ease and positioning precision
3Shape
If the infrared sensor is positioned inside the display device, then the appearance is improved, but the sensor accessibility for maintenance is reduced
Solution Approach 1:
The display device is segmented into separable components with the infrared sensor mounted on a separate substrate that can be independently accessed. The sensor assembly can be removed from the mounting hole and the substrate can be detached, allowing maintenance personnel to access and replace the sensor without disassembling the entire display device
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The internal positioning of the infrared sensor enhances the aesthetic appeal of the display device while maintaining its functionality, providing a seamless user experience by hiding the sensor from view.
Implementation Method 1
an infrared sensor inserted into the mounting hole
Implementation Method 2
an infrared lens positioned on at least a portion of a front surface of the cover

AI summary
A display device is disclosed. The display device includes a display panel, a front cover including a front part shielding an edge area of a front surface of the display panel and a side part shielding a side surface of the display panel, a mounting hole being formed on the side part, a guide panel positioned between the display panel and the front cover and coupled to the side surface of the display panel, a backlight unit positioned at a rear surface of the display panel, a frame positioned at a rear surface of the backlight unit, and an infrared sensor inserted into the mounting hole. The present disclosure can provide an apparently neat display device by positioning the infrared sensor inside the display device.
