Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple display driving chips are used to drive different display areas, then the display performance and reliability are improved, but the device cost and complexity increase
Solution Approach 1:
The display panel is divided into multiple display areas (first display area and second display area), each driven by separate gate driving circuits. This segmentation allows independent control of different regions while sharing common data lines and a single display driving chip, thus maintaining display performance without proportionally increasing chip quantity.
Solution Approach 2:
The display driving chip is designed to provide multiple trigger signals (first trigger signal and second trigger signal) that can control different gate driving circuits. This multi-functional capability allows a single chip to drive multiple display areas, reducing the total number of chips needed while maintaining reliable control over each region.
2Manufacturing precision
If multiple display driving chips are used to drive different display areas, then the control precision over each area is improved, but the manufacturing cost increases
Solution Approach 1:
Common data lines are merged and shared across multiple display areas, reducing the total number of data lines required. The display driving chip is merged to provide control for multiple areas through different trigger signals. This combining approach maintains precise control over each area while reducing component count and manufacturing cost.
Solution Approach 2:
The control architecture transitions from a one-to-one mapping (one chip per area) to a many-to-one relationship (one chip controlling multiple areas through different signal dimensions). The display driving chip operates in multiple signal dimensions by providing different trigger signals to different gate driving circuits, achieving precise control without increasing chip quantity.
3Device complexity
If a single display driving chip is used to drive multiple display areas, then the cost and complexity are reduced, but the flexibility in controlling different areas may be limited
Solution Approach 1:
The gate driving circuits are designed to be dynamically controllable through different trigger signals from the display driving chip. The first gate driving circuit and second gate driving circuit can be independently activated or deactivated based on which display area needs to be driven, providing flexible adaptability while using a single chip.
Solution Approach 2:
The gate driving circuits serve as intermediary components between the single display driving chip and the multiple display areas. These intermediaries enable the chip to flexibly control different areas by routing different trigger signals to different gate driving circuits, thus maintaining control versatility without requiring multiple chips.
