LED screen resolution refers to the number of distinct pixels (picture elements) that make up the display, typically measured as the total number of horizontal pixels multiplied by vertical pixels (e.g., 1920×1080 for Full HD). It is a fundamental metric that determines the screen’s ability to repro
An LED screen pixel (short for “picture element”) is the smallest discrete unit of light that makes up an LED display, analogous to a single dot in a printed image. In LED screens, each pixel consists of one or more LED chips (light-emitting diodes) arranged in a fixed pattern, along with associated
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
