Innovation Solution
Incorporating a planarization layer with notches and LEDs in the side display region, along with reflective and diffusive layers, to enable image display and minimize splicing seams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional liquid crystal display panels are spliced together to create a spliced display device, then the display area is expanded, but visible splicing seams are created between the panels, reducing display quality
Solution Approach 1:
The patent merges the liquid crystal display region with the side display region by extending the planarization layer from the liquid crystal display region to the side display region, creating a unified display structure that eliminates the visual boundary between active and inactive areas, thereby removing splicing seams when panels are concatenated
Solution Approach 2:
The side display region is transformed from an inactive area to an active display region by incorporating LEDs and extending the planarization layer, enabling the same structural elements to serve dual purposes: supporting liquid crystal pixels in the central region and LED light sources in the side region, thus eliminating the need for separate inactive borders
2Adaptability or versatility
If the planarization layer is extended to the side display region with notches for LEDs, then image display capability is added to the side region, but the structural complexity increases
Solution Approach 1:
The planarization layer is segmented by forming notches that accommodate individual LEDs in the side display region, allowing the same planarization layer structure to serve both the liquid crystal display region and the LED-based side display region with differentiated local functions
Solution Approach 2:
The display capability is extended from the traditional two-dimensional liquid crystal display region into the side display region by adding vertical LED structures within notches of the planarization layer, creating a multi-functional display surface that utilizes both horizontal and vertical spatial dimensions
