N-Only Display Driver Circuit for Pulse Signal Generation

The patent uses only n-type transistors throughout the entire driving circuit, replacing the traditional mixed n-type and p-type transistor architecture. This homogenization of transistor types simplifies the manufacturing process while maintaining the circuit's ability to generate both positive and negative pulse signals through clever circuit design involving pull-up and pull-down units

The n-type transistor-based driving circuit is designed to perform multiple functions: generating positive pulse signals, generating negative pulse signals, and providing both to the compensation circuit. This multi-functionality is achieved through the interaction of pull-up units (for positive pulses) and pull-down units (for negative pulses), both implemented using only n-type transistors

The patent merges the functions of separate n-type and p-type transistor driving circuits into a single unified circuit architecture using only n-type transistors. The pull-up unit and pull-down unit are integrated within the same circuit structure, eliminating the need for separate circuit blocks and reducing overall device complexity

The patent extracts and eliminates the p-type transistor component from the traditional dual-transistor driving circuit, retaining only n-type transistors. This extraction simplifies the circuit structure by removing unnecessary components while preserving the essential functionality of generating both positive and negative pulse signals through the pull-up and pull-down units
