Solution Overview

Problem

Existing displays, particularly LED and OLED displays used in studio environments, suffer from defects that compromise the quality of both visual and acoustic performance, necessitating complex manipulations to make images acceptable for viewers and recordings.

Innovation Solution

The solution involves optimizing LED displays for studio applications by improving visual performance through methods such as reducing frame delay, using programmable vertical sync updates, minimizing banding effects, adjusting current settings for individual colors, compensating for RLC behavior and temperature effects, and enhancing acoustic performance by reducing noise and sound reflections using acoustic materials and open structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If LED displays are used in studio environments, then visual performance is improved, but acoustic performance deteriorates due to noise and sound reflections

Engineering Contradiction:

Improvevisual performanceVSAvoidacoustic performance

Core Design Contradiction:

Illumination intensityVSObject-generated harmful factors

Solution Approach 1:

The display surface is segmented into individual LED elements with spacing between them, creating an open structure that allows sound to pass through rather than reflect off a solid surface. This segmentation maintains visual display functionality while improving acoustic performance by reducing sound reflections.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the display structure are given different properties: the LED elements provide light emission for visual performance, while the spaced arrangement and optional acoustic materials provide acoustic transmission. This local differentiation allows simultaneous optimization of both visual and acoustic characteristics.

Inventive Principle:

Principle #3Local quality

2Reliability

If complex manipulations are performed to correct display defects, then image acceptability is improved, but device complexity increases

Engineering Contradiction:

Improveimage acceptabilityVSAvoidmanipulation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The display is pre-configured with optimized LED spacing, positioning, and optional acoustic materials during manufacturing to inherently reduce reflections and improve image quality. This preliminary design approach eliminates the need for complex post-installation manipulations to correct defects.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The design accepts that LED displays generate some reflections, but converts this potential harm into a benefit by strategically positioning LEDs and using spacing to create desired visual effects while minimizing harmful reflections. The open structure transforms what could be a source of interference into an acoustic advantage.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Object-generated harmful factors

If acoustic materials are added to reduce sound reflections, then acoustic performance is improved, but device complexity increases

Engineering Contradiction:

Improvesound reflectionsVSAvoidstructure complexity

Core Design Contradiction:

Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The display structure serves multiple functions simultaneously: the spaced LED arrangement provides both visual display and acoustic transmission, while optional acoustic materials attached to the rear provide both sound absorption and structural support. This multi-functionality reduces the need for separate acoustic treatment components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The display structure is designed asymmetrically with the LED elements positioned on one side and acoustic materials on the other, allowing light to pass through to the viewing side while sound is absorbed or transmitted from the opposite side. This asymmetric arrangement efficiently separates optical and acoustic functions without requiring complex multi-layer structures.

Inventive Principle:

Principle #4Asymmetry
