Frequently asked questions about LED video wall advertising screens for LED users
What is the common questions about led display screens? be it indoor stage flexible displays or outdoor advertising walls.
What is pixel pitch?
Pixel pitch is the distance between the center of an LED and the LED next to it. The smaller the pixel pitch, the better the resolution and picture quality of the LED.
How are LEDs different from traditional screens?
While traditional LCD screens are typically used inside, LEDs are effective in practically any environment.They are designed to remain bright and visible even under direct sunlight and withstand most weather conditions.Unlike LCD screens, they are extremely durable and can be used for projects on a much larger scale.
What can LEDs be used for?
LED screens can be used for practically anything. Any image or video can be shown on them. Our engineers here at Street Communication can manipulate LED screens into a wide range of shapes and sizes, creating endless possibilities. Furthermore, LEDs work well both indoors and outdoors as they are exceptionally durable.
Which screen is best for me?
Choosing a screen is difficult because many factors need to be taken into account. Typically screens with smaller pixel pitches are superior indoors, while those with larger are better outside. We offer consultancy to help you reach a decision, so please reach out to us.
How does the viewing angle affects the image quality?
Making the smartest choice for your LED display can be difficult depending on the context of your project. The viewing angle depends on the brightness of the screen. Depending on the angle the viewer is watching the screen, colors and saturation can vary and give the image a blur effect. To chose your display wisely, read more on viewing angles.
How does the pixel pitch affect the screen resolution?
Before choosing your display your should know a few tricks that will help you take the right direction. Depending on the viewing distance needed for the project, the pixel pitch of the LED display is the first information you want to look for, read more on pixel pitch, resolution and ideal viewing distance here.
How to help the user to select the appropriate display?
(1) to display content
(2) visual distance, the perspective of the confirmation
(3) Screen resolution requirements
(4) installation of environmental requirements
(5) cost control
How are LED displays better than Video Projectors?
Video projectors often seem like an easier and cheaper solution, but they dont display the same quality image, the same brightness and can’t adapt to any context like innovative LED displays do.
Paste the LED outdoor screen can use the table, why?
Not. Demanding outdoor screen installation structure, SMD LED unable to adapt to the harsh outdoor environment.
The outdoor screen brightness higher, SMD LED unable to meet the outdoor screen brightness.
Display can not use the notebook control, why?
Not. The notebook computer’s graphics card is built-in, can not be achieved with the control system connection,
the current BOE have a notebook with a DVI interface, notebook control.
Display’s aspect ratio in general?
Graphic screen: to determine the content displayed; Video Screen: general close to 4:3 or 4:3; the ideal ratio is 16:9.
Why outdoor screen production cycle is long?
(1) procurement of raw materials: the LED lamp procurement cycle is longer, especially imported die, order cycle takes 4-6 weeks;
(2) The production process is complex: subject to the PCB design, production casing, plastic irrigation, adjusting white balance;
(3) strict structural requirements: the general cabinet design, the need to consider the wind, rain, lightning.
Understanding the scan mode of a led wall screen
The scan mode of a LED wall screen can be an important parameter to choose between several tiles. The scan mode has indeed an impact on two parameters of your screen: the light perception and the electric consumption. It must be associated with a third parameter, the refresh rate which, if high, can compensate for a low scan ratio.There are several modes of scanning: static mode, 1/2 scan, 1/3 scan, 1/4 scan, 1/8 scan, etc.
What is the scan mode can of a led wall screen?
Principle Simplified: Each micro controller has a number of pins and can drive up to the same number of led chips. Each chip manages a led line. The scan mode determines the ratio of the number of lines of led piloted simultaneously to the total number of lines of each module.
