Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If liquid crystal panels are used, then display function is achieved, but reaction time is slow and power consumption is high
Solution Approach 1:
The patent removes the backlight unit from the display structure, extracting the light source function from the liquid crystal panel. This eliminates the need for high-power backlight illumination and enables the use of self-emissive OLED pixels, dramatically reducing power consumption while improving response time through direct organic light emission
2Volume of moving object
If liquid crystal panels are used, then display function is achieved, but compact design is difficult due to backlight requirement
Solution Approach 1:
The backlight unit is completely removed from the display structure. The liquid crystal panel is transformed into a self-emissive OLED panel where organic light-emitting diodes directly generate light, eliminating the complex multi-layer backlight structure and enabling ultra-thin display design
Solution Approach 2:
The passive liquid crystal light modulation system is replaced with an active organic light-emitting diode system that generates light directly through electroluminescence, substituting the mechanical/optical backlight assembly with a self-emissive semiconductor structure
3Use of energy by moving object
If OLED panels are used, then energy efficiency is improved, but service life is short and production yield is poor
Solution Approach 1:
The patent employs a composite structure combining inorganic light-emitting diode materials with organic encapsulation layers. The inorganic LEDs provide long service life and high reliability, while the organic encapsulation maintains the energy efficiency benefits, creating a hybrid system that achieves both durability and energy efficiency
4Area of stationary object
If multiple display modules are assembled, then large screen is achieved, but steps and gaps appear among modules
Solution Approach 1:
The display is divided into multiple independent display modules that can be manufactured separately and then assembled. Each module contains its own organic light-emitting diode array and control circuitry, allowing for modular manufacturing and assembly while maintaining consistent display quality across the entire screen area
