An LED, or Light-Emitting Diode, is a semiconductor device that converts electrical energy directly into visible light (or infrared/ultraviolet radiation, depending on the type) when an electric current passes through it. Unlike traditional incandescent bulbs that rely on heating a filament to produ
An LED screen flat cable, also known as an “LED ribbon cable” or “FPC (Flexible Printed Circuit) cable,” is a thin, flexible electrical cable used to transmit power and data between the components of an LED display system—including LED modules, driver boards, control cards, and power supplies. Unlik
An LED screen cabinet, also referred to as a “display enclosure” or “module housing,” is a structural and protective component that houses the LED modules, power supplies, driver boards, and control cards of an LED display system. Unlike simple frames, LED screen cabinets are engineered to provide m
An LED screen mask, also known as a “front mask” or “display bezel,” is a protective and aesthetic component that covers the front surface of an LED display—shielding the LED chips, PCB, and internal components from physical damage, dust, and environmental factors while enhancing the visual experien
An LED screen power supply is a critical component responsible for converting alternating current (AC) from the mains into stable direct current (DC) that powers the LED modules, driver boards, and control cards of an LED display system. Unlike generic power supplies, LED screen power supplies are e
An LED screen control card, also known as an “LED controller” or “sign controller,” is the central command unit of an LED display system, responsible for receiving, processing, and transmitting content data to the LED modules or driver boards. It acts as a bridge between the user’s content source (s
An LED screen driver board, also known as an “LED driver PCB” or “scan board,” is a critical electronic component that regulates the flow of electrical current to the LED chips in an LED display—controlling their brightness, color, and refresh rate. Without a driver board, LED chips would receive un
An LED display unit, often referred to as a “cabinet” or “panel unit,” is a self-contained assembly that integrates multiple LED display modules, a power supply, a control board, and a structural frame—serving as a larger, more functional building block for large-scale LED screens. Unlike individual
An LED display module is a fundamental, pre-assembled unit that serves as the building block of LED screens, combining LED chips, a circuit board, a protective cover, and connectors into a single, ready-to-install component. Unlike individual LED chips or complete screens, these modules are designed
