Solution Overview
Problem
There is a need for a decorative lighting solution for display apparatuses like monitors and TVs that can enhance their aesthetic appeal by providing a decorative effect on the rear surface, which is often exposed in home or office settings.
Innovation Solution
A display apparatus with a decorative lighting device featuring an annular total reflection mirror, an annular half mirror, an annular light source, and a pattern forming member, which creates an infinity mirror effect when the light sources are turned on, along with a slide clamp mechanism to adjust the distance between the user and the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources and mirrors are arranged in a circular recessed portion to create an infinity mirror effect, then the decorative effect is improved, but the device complexity increases
Solution Approach 1:
The patent implements nesting by placing the annular light source between the annular total reflection mirror and the annular half mirror within a circular recessed portion. The pattern light source is nested within the light guide, which is itself nested within the circular recessed portion. This nested arrangement allows multiple functional components to be integrated in a compact space, achieving the infinity mirror decorative effect while controlling structural complexity.
Solution Approach 2:
The patent utilizes the vertical dimension by creating a circular recessed portion in the rear surface, allowing light sources and mirrors to be arranged in multiple layers along the depth direction. The annular total reflection mirror, annular half mirror, and annular light source are positioned at different depths, creating a three-dimensional infinity mirror effect that enhances decorative lighting while efficiently using available space.
2Illumination intensity
If a pattern forming member is inclined at an acute angle with respect to the annular half mirror, then the pattern reflection is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent specifies that the pattern forming member is inclined at an acute angle with respect to the annular half mirror, which optimizes the reflection of patterns onto the total reflection mirror. By defining the angle as acute (greater than 0 degrees and less than 90 degrees) rather than requiring a precise specific value, the design achieves good pattern reflection visibility while allowing reasonable manufacturing tolerances.
3Illumination intensity
If the rear surface of the display apparatus is exposed toward the center of the room, then the decorative lighting effect is improved, but the light may cause glare or discomfort to users
Solution Approach 1:
The patent applies local quality by using an annular half mirror that selectively reflects and transmits light. The half mirror allows the infinity mirror decorative effect to be visible from the front while controlling the direction and intensity of reflected light. This local optical property adjustment helps prevent glare to users while maintaining the decorative lighting effect on the exposed rear surface.
Solution Approach 2:
The annular half mirror acts as an intermediary between the light sources and the external environment. It mediates the light from the annular light source, allowing partial reflection to create the decorative infinity mirror effect while partial transmission prevents excessive light intensity and glare from reaching users in the room.
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 solution provides a visually appealing decorative effect on the rear surface of display apparatuses and allows for adjustable positioning, enhancing user experience through customizable lighting scenarios and improved aesthetics.
Implementation Method 1
an annular total reflection mirror disposed in the circular recessed portion; an annular half mirror disposed in the circular recessed portion on an outer side of the annular total reflection mirror
Implementation Method 2
the pattern of the pattern forming member is reflected between the annular total reflection mirror and the annular half mirror

AI summary
A display apparatus includes a display panel supported within a case having a rear surface including a circular recessed portion. An annular total reflection mirror and an annular half mirror are disposed in the circular recessed portion with an annular light source provided therebetween. A pattern forming member is disposed on an outer side of the annular half mirror and is configured to be reflected by the annular total reflection mirror. A pattern light source is configured to supply light to the pattern forming member so that the pattern is reflected on the annular total reflection mirror. When the annular light source and the pattern light source are turned on, the pattern of the pattern forming member is reflected between the annular total reflection mirror and the annular half mirror.
