Solution Overview
Problem
The manufacturing of large-sized and curved display devices is challenging due to the need for complex and costly processes, particularly in integrating self-luminous elements directly on substrates, which increases costs and technical difficulties.
Innovation Solution
A display device comprising a display substrate with a display layer and power supply, where the display element includes a base member, transreceivers, and a driving circuit that can receive and transmit power and image signals wirelessly, allowing for the formation of small-sized display elements that can be applied in various shapes without substantial cost increases, enabling efficient manufacturing of large or curved devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If self-luminous devices are manufactured directly on curved substrates, then display device shape versatility is improved, but manufacturing complexity and cost increase substantially
Solution Approach 1:
The display device is divided into separate modules: a flat display element and a curved substrate. The display element is manufactured independently on a flat substrate using conventional processes, then transferred to the curved substrate. This segmentation allows each component to be optimized separately, avoiding the complexity of direct manufacturing on curved surfaces.
Solution Approach 2:
The invention transitions from attempting to manufacture display elements directly on curved surfaces (2D curved manufacturing challenge) to manufacturing on flat surfaces and then transferring (adding the dimension of transferability). This approach uses flat-panel manufacturing technology which is well-established, and overcomes the technical difficulties of curved substrate integration through the transfer process.
2Area of stationary object
If self-luminous devices are manufactured directly on large substrates, then display device size is improved, but manufacturing cost and time increase substantially
Solution Approach 1:
Large display devices are constructed by assembling multiple smaller display elements on the substrate rather than manufacturing one large display element. This modular approach allows parallel manufacturing of multiple small elements, significantly improving productivity while achieving large overall display sizes through composition.
3Manufacturing precision
If conventional manufacturing methods are used for curved display devices, then manufacturing precision is maintained, but ease of manufacture deteriorates
Solution Approach 1:
Instead of attempting to manufacture display elements directly on curved substrates (the conventional difficult approach), the invention inverts the process: manufacture display elements on flat substrates where precision is easier to maintain, then transfer them to curved substrates. This reversal of the manufacturing sequence preserves manufacturing precision while dramatically improving ease of manufacture.
