Engineering Contradiction Analysis
1Measurement precision
If the size of light emitting devices is reduced to increase pixel density, then display resolution is improved, but the ability to arrange terminals for leading wires and control the devices is lost
Solution Approach 1:
An IC input structure is introduced as an intermediary component between the external control system and the miniaturized light emitting devices. This structure includes IC input connecting terminals that receive control signals and transmit them to the light emitting devices, enabling effective control despite the devices' small size. The intermediary structure bridges the gap between macro-scale control systems and micro-scale light emitting elements.
Solution Approach 2:
The terminal arrangement problem is resolved by transitioning from a planar arrangement to a three-dimensional structure. The IC input structure extends in the vertical dimension, with connecting terminals arranged at different heights and positions. This dimensional change allows multiple terminals to be packed into a smaller footprint area, enabling control of miniaturized devices without compromising terminal accessibility.
2Ease of operation
If conventional terminal arrangement methods are used, then control of light emitting devices is simple, but it becomes impossible to control devices when their size is very small
Solution Approach 1:
The IC input structure is designed with multi-functionality to address both control simplicity and small device compatibility. It serves multiple functions: receiving control signals from external sources, transmitting signals to multiple light emitting devices, and adapting to different device configurations. This universal structure can be applied across various display sizes and configurations, maintaining ease of operation while enabling control of miniaturized devices.
