Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If LCD panels are tiled together to achieve large display sizes, then the supply of large panels can be increased, but visible tiled lines appear between panels which affect the viewing experience
Solution Approach 1:
The patent extracts the boundary region from the display region and places LED pixels specifically in this boundary region. This separation allows the boundary to be treated differently from the display area, enabling seamless tiling by illuminating the boundaries between panels while maintaining normal LCD display functionality in the display regions.
Solution Approach 2:
The patent applies different pixel types to different regions: LCD pixels in the display region for normal image display, and LED pixels in the boundary region for boundary illumination. This local differentiation allows the boundary to be illuminated seamlessly across panel joints while the display region maintains its original functionality.
2Area of stationary object
If the panel size is increased to meet market demand, then the viewing experience can be enhanced, but the cost increases and yield decreases due to physical limitations
Solution Approach 1:
The patent divides the panel into display region and boundary region, allowing different manufacturing approaches for each. The display region uses standard LCD panel manufacturing, while the boundary region uses LED pixel integration. This segmentation enables modular assembly of multiple panels, avoiding the need to manufacture extremely large single panels and thus maintaining high yield and reasonable costs.
3Object-affected harmful factors
If LED pixels are arranged in the boundary region and connected by light-emitting circuits, then seamless tiling can be achieved, but the device complexity increases
Solution Approach 1:
The patent merges the boundary illumination function with the existing panel structure by integrating LED pixels into the boundary region of the same substrate. The light-emitting circuits are arranged in series along the boundary, combining multiple functions (boundary illumination, tiling seamlessness) into a unified structure rather than adding separate complex systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables seamless tiling by normal operation of LED pixels, enhancing the viewing experience and overcoming size limitations in panel production.
Implementation Method 1
The LED pixels are arranged in an array in the boundary region. The light-emitting circuits are arranged in series in the boundary region along a first direction and are electrically connected to the LED pixels to provide multiple light-emitting signals for the LED pixels
Implementation Method 2
The LED pixels may be lit up based on the light-emitting signal of the light-emitting circuit
