Curved Display Panel Fabrication via Substrate Thinning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display panels are difficult to manufacture in a curved shape and incur high costs, and multi-layered displays suffer from image noise due to interference between overlapped panels, requiring additional assembly processes.
Innovation Solution
A method to fabricate a curved-surface display panel by partially thinning and bending existing display panels with guide members and forming light-transmitting reinforcing layers to maintain the curved shape, eliminating the need for additional diffuse layers and simplifying assembly.

Engineering Contradiction Analysis
1Shape
If conventional flexible liquid crystal display panels are manufactured using flexible substrates instead of glass substrates to enable bending, then the display can be bent by external bending force, but the manufacturing process becomes difficult and the manufacturing cost increases
Solution Approach 1:
The invention changes the thickness parameter of the substrate by selectively removing portions of the substrate thickness in specific regions. This allows the substrate to be bent into a curved shape while maintaining structural integrity, avoiding the need for complex flexible substrate manufacturing processes. The selective thinning creates a thickness gradient that enables controlled bending without increasing manufacturing difficulty.
2Object-affected harmful factors
If a diffuse layer is interposed between two LCD panels to prevent noise by the overlap of the LCD panels, then image noise is removed, but an additional assembling process is required and productivity deteriorates
Solution Approach 1:
The invention removes the diffuse layer component entirely from the display structure. Instead of adding a diffuse layer to prevent Moire noise, the patent uses a curved-surface display panel that inherently eliminates the interference pattern through its curved geometry, thereby removing the need for additional assembly steps and maintaining high productivity.
Solution Approach 2:
Rather than adding a diffuse layer to scatter light and reduce noise, the invention inverts the approach by using a curved surface that directs light in a specific pattern, naturally preventing Moire interference without requiring additional optical components or assembly steps.

AI summary
A curved-surface display panel fabrication method for fabricating a curved-surface display panel using a flat display panel having a first substrate and a second substrate includes: paring partially outer surfaces of the first substrate and the second substrate so as to reduce thicknesses thereof to a predetermined thickness; bending the pared flat display panel to a desired curved shape; attaching a first guide member which has a shape corresponding to the desired curved shape to the first substrate with a predetermined gap from the pared outer surface thereof and attaching a second guide member with has a shape corresponding to the desired curved shape to the second substrate with a predetermined gap from the pared outer surface thereof; and forming light transmitting reinforcing layers respectively in a space between the first guide member and the first substrate and a space between the second guide member and the second substrate.
