Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If self-luminous elements are used to achieve deep black color and superior video display, then black level degradation is prevented, but high-luminance display capability is limited
Solution Approach 1:
The patent applies dynamics by enabling self-luminous elements to operate in two distinct modes: normal mode for standard video display and boost mode for high-luminance display. The control device dynamically switches between these modes based on the display requirements, allowing the same element to adapt its luminance output from normal levels to exceeded maximum luminance levels as needed.
Solution Approach 2:
The patent utilizes parameter changes by modifying the luminance output parameter of self-luminous elements. Through control signals, the elements can change their emission parameter from normal maximum luminance to exceeded maximum luminance in boost mode, enabling the display to represent both normal and extremely bright scenes accurately.
2Adaptability or versatility
If boost light emission is applied to display high-luminance content, then video expression is enhanced, but power consumption and heat generation increase
Solution Approach 1:
The patent applies local quality by implementing boost mode only for specific self-luminous elements that require high luminance output, rather than activating all elements at maximum power. The control device selectively applies boost light emission only where needed in the display, maintaining normal operation for other elements and thus managing overall power consumption and heat generation.
