Calculating the cabinet dimensions for an LED screen involves considering several factors, including the screen size, aspect ratio, pixel pitch, and any specific requirements or constraints. Here’s a general approach to help you calculate the cabinet dimensions:
1. Determine the screen size: Decide on the desired screen size, usually measured in inches or centimeters. This will depend on your specific needs and available space.
2. Choose the aspect ratio: Determine the aspect ratio for your LED screen, which is the ratio of width to height. Common aspect ratios include 16:9 (widescreen) or 4:3 (standard).
3. Determine the pixel pitch: Pixel pitch refers to the distance between adjacent pixels on the LED screen and is typically measured in millimeters (mm). It affects the resolution and image clarity. Choose an appropriate pixel pitch based on your viewing distance and desired visual quality.
4. Calculate the number of pixels: Multiply the screen width by the number of pixels per unit length based on the chosen pixel pitch. For example, if the pixel pitch is 2mm and the screen width is 1000mm, you would have 500 pixels horizontally (1000mm / 2mm = 500 pixels).
4. Calculate the number of rows: To maintain the aspect ratio, calculate the number of rows by multiplying the number of pixels horizontally by the aspect ratio. For example, if you have 500 pixels horizontally and a 16:9 aspect ratio, you would have approximately 281 rows (500 pixels * (9/16) = 281.25 rows).
5. Determine the cabinet dimensions: Divide the screen width and height by the number of pixels or rows to determine the cabinet dimensions. Keep in mind that each cabinet typically contains multiple LED modules or panels.
6. Consider additional factors: Consider any additional factors specific to your setup, such as the required space for mounting brackets, ventilation, cabling, and any structural or design considerations.
The specific calculations and requirements may vary based on LED module specifications, and your specific project needs. Refer to the specifications, guidelines, or consult with an LED screen professional for accurate and detailed cabinet dimension calculations.

COB LED display stands for “Chip on Board” LED display. In this technology, multiple LED chips are mounted directly onto a PCB (Printed Circuit Board) substrate, and then covered with a layer of phosphor to create a single lighting module. This results in a dense concentration of LEDs, which enables the COB display to produce high-quality illumination with a very high lumen output.
COB LED displays have several advantages over other LED display technologies. First, because the LEDs are closely packed together, they produce a uniform light output with no visible gaps or seams between the individual chips. This results in a smoother, more continuous image without the “mosaic effect” that can be seen in some other types of LED displays.
Additionally, COB LED displays are highly energy-efficient, due to their high luminous efficacy (lumens per watt). They also have a longer lifespan than traditional LED displays, and require less maintenance, as they do not have any moving parts or components that need frequent replacement.
COB LED displays are commonly used in a variety of applications, such as indoor and outdoor advertising, large-scale video walls, and stage lighting for concerts and other events.
A GOB LED display refers to an LED screen that utilizes a technology called “glass on board” (GOB) during the manufacturing process. GOB LED displays are made by placing the LED chips directly onto a PCB (printed circuit board) and then covering them with a layer of glass. The glass protects the LED chips from damage and also enhances the display’s durability and reliability.
Compared to traditional LED displays, GOB LED displays have several advantages. First, the glass layer provides an additional level of protection against impact and moisture, making them more resistant to damage and weathering. Second, the GOB technology allows for a higher pixel density, resulting in a clearer and sharper image. Finally, the glass layer can also improve the viewing angle and color accuracy of the display.
GOB LED displays are commonly used in a wide range of applications, such as outdoor advertising, digital signage, sports arenas, and concerts.
A flexible soft LED display is a type of LED screen that is made up of flexible materials that can be bent, curved or even rolled up. The display is made up of a matrix of LEDs that are mounted onto a thin and flexible substrate, such as a plastic or rubber material. The flexible nature of the display allows it to be easily shaped to fit around various objects or surfaces, making it ideal for a wide range of applications such as curved walls, cylindrical columns, and even wearable devices.
Flexible soft LED displays are also lightweight and thin, making them easy to transport and install. They are commonly used in various indoor and outdoor settings such as shopping malls, trade shows, concerts, sports events, and advertising displays. The displays offer high-resolution graphics and bright, vivid colors that are visible from a distance, making them an effective way to grab people’s attention and convey messages or advertisements.
Taxi top LED displays in the USA are primarily used by taxi companies and ridesharing services such as Uber and Lyft.
