: The speed at which the scan driver moves from the top of the screen to the bottom determines the display's refresh rate (e.g., 60Hz or 120Hz). Modern scan drivers support Variable Refresh Rates (VRR) to save power by slowing down when the screen content is static.
In modern active-matrix displays, such as (Active-Matrix Organic Light-Emitting Diode) and LCD (Liquid Crystal Display), the screen is organized into a grid of pixels. A scan driver, often referred to as a gate driver or row driver , performs the essential task of turning these pixels on and off sequentially. scan driver
: Increasingly, scan drivers are integrated directly onto the glass substrate of the display panel rather than using external chips. This "Gate-in-Panel" (GIP) approach allows for narrower bezels and lower manufacturing costs. 2. Emerging Technologies in Scan Driver Circuits : The speed at which the scan driver
Research into scan drivers is focused on efficiency, reliability, and the demands of new form factors like foldable screens. A scan driver, often referred to as a
: The driver generates a series of pulses that travel across each row (scan line). When a specific row is "scanned," its transistors are turned on, allowing the data driver (source driver) to fill the pixels in that row with specific brightness levels.
