Core Design Contradiction:
Measurement precisionVSTemperature

Solution Approach 1:

The harmful heat generated by the integrated circuit chip is extracted and separated from the chip itself by introducing a heat dissipating pad that contacts the chip. This pad absorbs and conducts the heat away from the chip, isolating the heat generation source from the sensitive electronic components while maintaining the high data transmission capability for high resolution display

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A heat dissipating pad is introduced as an intermediary element between the integrated circuit chip and the surrounding environment. This pad serves as a thermal conductor that mediates the heat transfer process, conducting heat away from the chip to the supporting member or housing, thereby protecting the chip from overheating while allowing high data transmission to continue

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If integrated circuit chips are mounted on driver and control circuit boards to enable high resolution display, then display capability is improved, but thermal management becomes inadequate

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The thermal management solution extends into a new dimension by adding a vertical heat dissipation path. The heat dissipating pad is positioned to contact the integrated circuit chip from above (or below), creating a third-dimensional thermal conduction path that is perpendicular to the circuit board plane. This allows heat to be conducted away from the chip in a direction orthogonal to the board, providing effective thermal management while maintaining the high capability display function

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
