Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If display device and sound system are separated, then manufacturing cost increases and device volume increases, but image and sound can be produced independently
Solution Approach 1:
The patent merges the display device and sound system into a single integrated unit. The display panel serves dual functions as both visual display and sound output device, eliminating the need for separate sound systems. This integration reduces manufacturing costs, decreases overall device volume, and simplifies the system architecture while maintaining independent functionality of image and sound production.
2Adaptability or versatility
If speaker is point sound source, then sound system structure is simple, but stereo sound associated with image movement is limited
Solution Approach 1:
The patent segments the sound output function across multiple independent units distributed throughout the display panel. Each pixel or pixel group acts as an independent sound source, allowing precise spatial control of sound output. This segmentation enables stereo sound to be associated with specific regions of the display, matching image movement and position, while maintaining relative simplicity in each individual sound generating unit.
3Reliability
If display device and sound system are separated, then each component can be optimized independently, but image and sound mismatch occurs
Solution Approach 1:
By merging the display and sound systems into a single integrated device, the patent ensures that image and sound are generated and output simultaneously from the same spatial location. This integration guarantees synchronization between image and sound, eliminating mismatches that occur when components are separate, while the modular pixel-level architecture keeps the integration manageable.
4Power
If separate sound system is added, then sound output capability is improved, but device volume increases
Solution Approach 1:
The patent makes the display panel universal by enabling it to perform multiple functions: visual display and sound output. Each pixel or pixel group serves dual purposes, eliminating the need for additional dedicated sound components. This multi-functionality maintains strong sound output capability while keeping the overall device volume compact, as no separate sound system is required.

AI summary
The present invention relates to an optical element capable of simultaneously outputting sound from the surface of a display device with an image, the optical element comprising: a first electrode member; a first dielectric elastomer layer disposed on the first electrode member; a second electrode member disposed on the first dielectric elastomer layer; and an optical crystal layer disposed on the second electrode member. Accordingly, in the present invention, image and sound are implemented simultaneously, and thus, it is possible to prevent defects due to mismatching of the image and the sound, and a separate sound system is not required when the display device is manufactured using the optical element, thereby making it possible to reduce components of an electronic product including the display device and reduce the manufacturing cost.
