LED display screen as a modern display device, has been widely used in various occasions, such as outdoor advertising, sports venues, stage rental, traffic guidance, etc.It can be so widely used, inseparable from its excellent display effect and stable performance.Today, LCF small series will start from the parameters of LED display screen, analyze it in detail, to help you better understand and choose LED display screen.

One, the classification of LED display

 According to the packaging mode of light emitting diode (LED), LED display can be divided into two major categories: surface mount (SMD) and dot matrix (DIP).Surface mount LED display adopts surface packaging technology, which directly attaches the LED chip to the circuit board, and then fixes the LED on the circuit board through coplanar packaging technology.Dot matrix LED display adopts traditional dot matrix packaging mode, which arranges the LED into a matrix form.Compared with dot matrix LED display, surface mount LED display has higher dot spacing, better display effect and more stable performance.

 Two, the main parameters of LED display

 1. Dot spacing

 Dot spacing refers to the center distance of two adjacent LED beads in the LED display.The smaller the dot spacing, the clearer the display effect, the higher the resolution.The common dot spacing is 2mm, 3mm, 4mm, 5mm, etc. The choice of point spacing depends on the application scenario and the demand of display content.

 2. Resolution

 Resolution refers to the number of pixels that can be displayed by the LED display screen.The higher the resolution, the more delicate the display effect.The resolution of the LED display screen is usually expressed in "width × height", such as 1920×1080, 3840×1200, etc.

 3. Brightness

 Brightness refers to the luminous intensity of the LED display screen in a unit area.The higher the brightness, the better the display effect of the display screen in direct sunlight and other strong light environment.The brightness of the LED display screen is usually expressed in nits (nit).According to different application scenarios, the brightness of the LED display screen can be divided into ordinary brightness (1000-3000nit) and high brightness (≥4000nit).

 4. Perspective

 Perspective refers to the range of display content that the audience can see when watching the LED display screen from different angles.The greater the perspective, the better the viewing effect.The perspective of the LED display screen is usually expressed in horizontal perspective and vertical perspective.In general, the horizontal perspective and vertical perspective should be above 120°.

 5. Color specification

 The color specification of the LED display screen is usually expressed in RGB (red, green and blue).According to different color requirements, the LED display screen can be divided into monochrome display screen, bicolor display screen and full color display screen.Among them, the full color display screen can display rich colors, which is suitable for outdoor advertising, stage rental and other occasions.

 6. Control system The control system of LED display screen refers to the equipment used to control the display content of the display screen.

Common control systems include synchronous control system, asynchronous control system and so on.The synchronous control system has high stability and reliability, which is suitable for the occasions that require real-time updates;the asynchronous control system has good flexibility, which is suitable for the occasions where the content is not updated frequently.

 7.Protection level

 The protection level of LED display screen refers to the dustproof and waterproof ability of the display screen.The higher the protection level, the wider the application scenario of the display screen.Common protection levels are IP20, IP30, IP50, IP60 and so on.For example, the IP65 level LED display screen has good dustproof and waterproof performance, which is suitable for the harsh outdoor environment.

 There are many parameters of LED display screen, and it is very important to understand and choose the appropriate parameters to ensure the display effect and performance.When choosing LED display screen, we should consider the parameters comprehensively according to the actual application scenario, display content, budget and other factors, and choose the most suitable display screen.At the same time, we should also pay attention to the technical strength and after-sales service of the manufacturer to ensure that we can buy a reliable quality and stable performance of LED display screen.

 The above is the summary of the parameters of LED display screen. I hope it will be helpful to you. At the same time, we welcome you to add or correct. LCF is a national special new "little giant" enterprise, set "hardware + software + content + interaction" as one of the LED display application and solution provider.
