OLED Display Circuit Gate Driving Unit for Pixel Density

The patent combines the Vth compensation function and gate driving function into a single integrated circuit module. The gate driving circuit simultaneously performs threshold voltage compensation for pixel transistors and generates gate driving signals, eliminating the need for separate independent circuits. This integration reduces the number of components and simplifies the overall circuit design while maintaining compensation accuracy through coordinated signal generation and processing.

The gate driving circuit is designed to perform multiple functions: it generates gate driving signals for pixel rows, performs Vth compensation for pixel transistors, and provides timing signals for data writing. By making the gate driving circuit universal and multi-functional, the patent eliminates the need for separate dedicated Vth compensation circuits, thereby reducing circuit complexity while maintaining compensation precision through integrated signal processing.

By merging the Vth compensation circuit and gate driving circuit into a single integrated unit, the patent reduces the area occupied by circuit components. This space optimization allows for higher pixel density on the display panel while maintaining functional reliability through the coordinated operation of compensation and driving functions within the same circuit architecture.

The patent reorganizes the circuit architecture by integrating multiple functions into a unified gate driving unit that operates across different functional dimensions (compensation, driving, timing). This dimensional reorganization of circuit functions reduces spatial requirements and enables higher pixel density without sacrificing the reliability of individual functions.
