Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light sensor is added to enable automatic brightness and contrast adjustment, then the adaptability to external environment is improved, but the device complexity increases
Solution Approach 1:
The light sensor enables the display panel to automatically sense ambient light intensity and adjust its own brightness and contrast without external intervention. The system serves itself by using the sensed light information to autonomously optimize display parameters, eliminating the need for manual user adjustment and improving adaptability to changing environmental conditions
Solution Approach 2:
The light sensor serves multiple functions: it detects ambient light intensity, provides feedback signals for brightness adjustment, and enables contrast optimization. By integrating this single component to perform multiple adaptive functions, the system achieves enhanced versatility without proportionally increasing complexity
2Area of stationary object
If the light sensor is placed in the display area between transistors, then the space efficiency is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The light sensor is strategically positioned in specific locations within the display area, utilizing the spaces between transistor structures. This localized placement optimizes space utilization by fitting the sensor into available gaps rather than requiring separate dedicated areas, thereby improving space efficiency while maintaining functional performance
Solution Approach 2:
The light sensor is integrated within the existing transistor structure layout, nesting the sensor component in the intervals between transistors. This nested arrangement allows the sensor to occupy otherwise wasted space, achieving higher space efficiency without requiring additional substrate area beyond what is already allocated for the transistor array

Implementation Method 1
since the light sensor is provided correspondingly in the display area of the first substrate, the outside environment of the display area can be sensed by the photosensor, and in particular, it is possible to perceive the change in the intensity of the outside light
