Problem
Conventional display-driving structures require multiple source driver circuit boards and an additional control circuit board to manage display signals, leading to complex wiring and inefficiencies, especially in larger, high-definition displays where precision and space constraints become significant.
Innovation Solution
A display-driving structure that utilizes two circuit boards with transmission wiring to distribute control signals, allowing source driver circuits on each board to receive necessary signals and drive the display panel, eliminating the need for an additional control circuit board by configuring different control circuits on each board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple source driver circuit boards and an additional control circuit board are used to manage display signals, then the display can achieve high definition and large size, but the wiring becomes complex and the device structure becomes more complicated
Solution Approach 1:
The patent combines the control circuit functions directly onto the source driver circuit boards, merging what were previously separate control and driver functions into a unified structure. This eliminates the need for a separate control circuit board and reduces wiring complexity while maintaining the capability to drive high-definition displays
2Measurement precision
If multiple source driver circuit boards are distributed to drive high-definition displays, then the display capability is improved, but the number of circuit boards and control structures increases
Solution Approach 1:
The patent integrates control circuitry directly onto the source driver circuit boards, combining multiple functions into unified boards. This reduces the total number of separate circuit boards needed while maintaining the capability to drive high-definition displays with multiple source driver circuits
3Adaptability or versatility
If an additional control circuit board is configured to provide control signals, then the control capability is improved, but the material usage increases and efficiency decreases
Solution Approach 1:
The patent merges the control circuit functions onto the existing source driver circuit boards, eliminating the need for a separate control circuit board. This integration improves signal transmission efficiency by reducing the number of intermediate connections and material usage while maintaining full control capability over the display signals
