Slim Frame Display Infrared Receiver Light Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with infrared remote control systems have an excessively wide bottom frame, which obstructs a slim design and affects the display's aesthetic appeal.
Innovation Solution
A light guide member is strategically positioned and designed to change the transmission direction of infrared control signals, allowing the infrared receiver to be shifted backward, with a narrower receiving end that only shows a slim profile, enabling efficient signal reception while maintaining a slim frame design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the infrared receiver is disposed at the front of the display device to receive infrared signals directly, then the signal reception is effective, but the frame becomes excessively wide and cannot achieve a slim design
Solution Approach 1:
The patent changes the spatial arrangement by disposing the infrared receiver at the rear of the display device instead of the front, utilizing the depth dimension (z-axis) to relocate the component. The light guide member then guides infrared signals from the front incident surface through the frame to the rear receiving surface, enabling effective signal reception while maintaining a slim front frame profile.
Solution Approach 2:
The light guide member serves as an intermediary component that bridges the gap between the front incident surface and the rear receiving surface. It transmits infrared signals through the frame structure, allowing the infrared receiver to be positioned at the rear while still receiving signals that appear to come from the front, thus resolving the contradiction between reception effectiveness and frame slimness.
2Reliability
If the light guide member is disposed at the bottom of the frame with the same thickness as the frame, then the infrared signal can be transmitted through the frame, but the frame appears wider and the display effect is compromised
Solution Approach 1:
The light guide member is positioned such that its incident surface is at the front of the frame while its receiving surface is at the rear, utilizing the depth dimension to hide the thickness of the light guide member. This arrangement allows the infrared transmission function to be maintained while the front appearance shows only a minimal profile, improving the display effect.
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
This solution enhances the display effect by maintaining a slim frame design while ensuring effective infrared signal reception, improving the overall appearance and functionality of the display device.
Implementation Method 1
a light guide member 4, wherein the light guide member 4 has a securing surface 40 for securing the light guide member 4 to the frame 1, a receiving end 42 formed at a display side of the display screen 2, and a light exiting surface 43; the width a1 of the receiving end 42 in a direction perpendicular to the frame 1 to which the light guide member 4 is secured is narrower than a width a2 of a light exiting surface 43 in the direction

AI summary
A display device comprises a display screen (2) and a frame (1) disposed around the display device (2), an infrared receiver (3) and a light guide member (4), wherein the light guide member (4) has a securing surface (422) through which the light guide member is secured to the frame (1), the light guide member (4) further comprising a receiving end (42) and a light exiting surface (423), the receiving end (42) formed at a display side of the display device (2), a width of the receiving end (42) in a direction perpendicular to the frame (1) to which the light guide member is secured is narrower than a width of the light exiting surface (423) in the direction. Only a narrower portion of the light guide member can be seen when a human being looks at the display device, thus improving display effect of the narrow frame of the display device.
