In the context of LED displays, “pitch” refers to the pixel pitch or pixel pitch size. Pixel pitch is a crucial specification that determines the spacing between individual pixels on an LED display screen. It plays a significant role in determining the display’s resolution, image clarity, and viewing distance. Here’s how pitch is relevant to …
“Nit” (symbol: nt) is a unit of measurement for luminance, specifically the luminance of a surface or an object. Luminance measures the brightness of an object as perceived by the human eye. In the context of LEDs (Light-Emitting Diodes) and displays, the term “nit” is often used to specify the brightness or luminance of the …
Luminance is a photometric measurement that quantifies the brightness of a surface or an object as perceived by the human eye. It is an important concept in lighting, display technology, and image processing. Luminance is typically expressed in units of candela per square meter (cd/m²) in the International System of Units (SI). Here are some …
A lumen is a unit of measurement that quantifies the total amount of visible light emitted by a light source, such as a bulb, lamp, or LED. In simpler terms, lumens indicate the brightness or light output of a light source. The higher the number of lumens, the brighter the light emitted by the source. …
Gamma correction, often referred to as gamma, is a crucial concept in the world of LEDs (Light-Emitting Diodes) and display technology. Gamma correction is a technique used to ensure that the brightness levels of displayed images or colors on an LED display are perceived by the human eye in a way that is consistent with …
DVI stands for “Digital Visual Interface,” and it is a video interface standard used to transmit digital video signals from a source device, such as a computer or DVD player, to a display device, such as a computer monitor or television. DVI was developed to replace older analog video standards like VGA (Video Graphics Array) …
LED stands for “Light-Emitting Diode.” It is a semiconductor device that emits light when an electric current passes through it. LEDs are widely used for various lighting applications and electronic displays due to their energy efficiency, long lifespan, compact size, and versatility. Here’s a more detailed definition of LEDs: 1.Semiconductor Device: LEDs are made of …
“Control PC” typically refers to a personal computer (PC) that is used for controlling or managing various devices, systems, processes, or applications. Control PCs are commonly used in industrial automation, home automation, data acquisition, and other fields where centralized control and monitoring are necessary. Here’s an overview of control PCs and their applications: 1.Industrial Automation: …
Contrast is the difference in brightness between the light emitted by the LEDs and the surrounding environment or adjacent areas. Achieving the right contrast level is essential for readability, visibility, and overall visual impact. Here’s how contrast level is relevant in LED applications: 1.Display Visibility: In LED displays, such as digital signs, billboards, and electronic …
Color temperature in LEDs (Light-Emitting Diodes) refers to the perceived warmth or coolness of the white light produced by the LED. It is measured in Kelvin (K) and is an important characteristic to consider when selecting LED lighting for various applications. Here’s how color temperature is defined and its relevance in LED lighting: 1.Warm White …
