Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate speaker is installed in a display device, then sound output function is provided, but space is occupied and design flexibility is limited
Solution Approach 1:
The patent combines the speaker function with the display panel by integrating vibration devices directly into the display structure. The display panel itself serves as the sound output component, eliminating the need for separate speakers and freeing up space within the display device.
Solution Approach 2:
The display panel is designed to perform multiple functions: visual display and sound output. By making the display panel itself capable of generating sound through integrated vibration devices, the system achieves multi-functionality without requiring additional dedicated components.
2Ease of operation
If sound is transmitted from the display panel, then in-screen sound is achieved, but sound quality deteriorates due to interference from reflections
Solution Approach 1:
The patent divides the display panel into multiple independent sound output regions or channels. By segmenting the sound emission areas, the system can control sound propagation paths more precisely and reduce interference from reflections off walls or ground surfaces.
Solution Approach 2:
The patent introduces acoustic isolation structures or sound channels as intermediaries between the vibration devices and the external environment. These intermediaries guide sound transmission while blocking or reducing reflected sounds that would otherwise interfere with audio quality.
3Reliability
If multiple vibration devices are integrated into the display panel, then sound quality and immersion are enhanced, but device complexity increases
Solution Approach 1:
The patent merges the vibration devices with the display panel structure, using the panel's existing components as part of the sound generation system. This integration approach enhances sound quality while avoiding the need for completely separate, complex audio subsystems.

AI summary
A display panel includes at least two first display units arranged along a column direction to form display unit columns, in a display unit column of the display unit columns, a distance L2 of sound channel centers of two adjacent first display units in the column direction is:2×W×tan(α2)wherein W is a vertical distance between a sound receiving position and a side surface of the display panel facing the sound receiving position; a is an angle between linear distances respectively from the sound channel centers of the two adjacent first display units to the sound receiving position in the display unit column, and the a is greater than 3.4 degrees.
