Signal processing capability: responsible for converting the digital signal input of the motherboard into a driving signal that can be recognized by the screen to determine the image quality and delicacy. Resolution matching: It must be strictly correlated to the screen resolution (such as 4K/8K), and mismatch will cause the screen to blur or not be displayed. Refresh rate support: High refresh rates (such as 120Hz/144Hz) need to be synchronized with the logic board, which will affect the smoothness of the dynamic picture. Interface type: Common interfaces include LVDS, eDP, TTL, etc., which must be consistent with the screen interface, otherwise they cannot be connected. Power stability: Relying on a stable 5V/12V power supply, voltage fluctuations can easily cause the screen to flicker or go black.
