Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional LED modules are assembled on PCB substrates, then true color display is achieved, but the minimum image pitch is three millimeters and the display lacks flexibility
Solution Approach 1:
The invention segments the rigid PCB substrate into flexible metallic board segments with conductive circuitry patterns, allowing the display to achieve both fine image pitch and flexibility. The metallic board is divided into multiple regions with independent conductive circuits that can be selectively activated, enabling high-resolution display while maintaining bendability.
Solution Approach 2:
The invention changes the substrate material parameter from rigid PCB to flexible metallic board, and modifies the circuit configuration from discrete component assembly to integrated conductive patterns. This parameter change enables simultaneous achievement of small image pitch (high resolution) and mechanical flexibility, resolving the contradiction between manufacturing precision and adaptability.
2Manufacturing precision
If LCD technology is used, then high resolution is achieved, but color saturation is low (about 70% NTCS) and reaction time is long (about 16 ms)
Solution Approach 1:
The invention merges the advantages of LED spontaneous light emission with high-resolution display structure. By integrating micro-scale LED light sources directly onto the flexible metallic board substrate, the system achieves both high resolution (through precise spatial arrangement) and high color saturation (through LED's intrinsic color purity exceeding 100% NTCS), while also reducing reaction time to less than 1 ms.
3Illumination intensity
If OLED display is used, then color saturation is high (about 100% NTCS) and reaction time is short (less than 1 ms), but the OLED light emitting layer needs pressurizing for protection
Solution Approach 1:
The invention replaces the fragile OLED light emitting layer with robust solid-state LED components that inherently resist oxidation and degradation. This substitution eliminates the need for complex pressurized encapsulation structures, simplifying the device design while maintaining high color saturation and short reaction time characteristics.
4Speed
If PDP display is used, then reaction time is short (less than 1 ms) and visual angle is wide, but power consumption is big and vacuum packing is needed
Solution Approach 1:
The invention changes the operating parameters by using low-power LED light sources with precise current control instead of high-power plasma discharge. The flexible metallic board substrate enables efficient heat dissipation, allowing the display to maintain short reaction time (less than 1 ms) and wide visual angle while significantly reducing power consumption and eliminating the need for vacuum packing.
