Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a convex lens is used to collect light from light-emitting elements, then light collection efficiency is improved, but the optical element may be damaged due to direct exposure to intense light
Solution Approach 1:
The patent introduces an insulating film as an intermediary layer positioned between the light-emitting element and the convex lens. This film serves as a protective barrier that prevents direct contact and potential damage to the optical element while still allowing light to pass through for collection, thus resolving the contradiction between improving light collection efficiency and ensuring optical element durability
Solution Approach 2:
The insulating film is placed in advance between the light-emitting element and the convex lens to provide protective cushioning. This pre-positioned protective layer prevents potential damage before it can occur, allowing the convex lens to function effectively for light collection without risking damage from intense light or physical contact
2Productivity
If the convex lens is positioned close to the light-emitting element for efficient light collection, then light usage efficiency is improved, but the risk of damage to the optical element increases
Solution Approach 1:
The insulating film acts as a mediator that enables the convex lens to be positioned close to the light-emitting element for efficient light collection while simultaneously protecting the optical element from damage. The film allows close proximity for productivity improvement without exposing the optical element to harmful factors
3Loss of energy
If a sealant with lower refractive index is used with the convex lens, then light collection toward the front direction is improved, but the device structure becomes more complex
Solution Approach 1:
The patent utilizes parameter changes by selecting a sealant with a specific refractive index property (lower than the convex lens material). This parameter difference is strategically used to improve light collection efficiency toward the front direction through refraction control, while the sealant is integrated into the existing device structure to minimize complexity increase

Function Achieved in This Case
The solution enables highly convenient, useful, and reliable functional panels and display devices by enhancing light collection and reducing damage to optical elements, thereby improving the efficiency and reliability of light emission.
Implementation Method 1
The optical element has a first refractive index N1, the optical element is a convex lens... The distance L1 has a relationship represented by Formula (i) with the first radius of curvature R1 and the first refractive index N1. Thus, light emitted from the first region can be collected toward the front direction
Implementation Method 2
The insulating film is interposed between the optical element and the first region, and the insulating film is in contact with the second surface... the optical element can be protected from breakage or damage associated with the use
Implementation Method 3
The sealant has a second refractive index N2, and the second refractive index N2 is lower than the first refractive index N1... light emitted from the first region can be collected toward the front direction of the first region
