how to choose LCD or LED fine pitch video wall?



How to choose the correct indoor fine pitch LED displays ?

1.View angle

View angles is deciding how many audience can view the LED screen clearly . Wider view angle , more people can view it . So it can make your cost and advertising maximization . The view angle is cause by encapsulation of the LEDs , therefore , if you have enough budget , choose the better encapsulation of the LED, and also take care of the mask covering the LED board.

2. Brightness 

Someone must noticed if the brightness is too high , it's hard for our eyes , but if too low , the screen will not clear enough. So the standard brightness for indoor LED display is 600-1000 nits.

3. Flatness

Bad flatness will absolutely make the effect of the LED screen worse , and the standard flatness is keeping ±1 mm . Our fine pitch LED display flatness reach to ±0.2 mm. So , when we are making the solution , die-casting aluminum cabinet will be the best for indoor LED displays .

4. The LEDs

There are two type of LEDs for indoor , white SMD LED and black SMD LED , the black LEDs we are using mostly for the pixel pitch which is lower than 5mm , and we have to choose the black LEDs for indoor LED screen , this is a very important point. All our LED black face LED.

5. Dead pixels

The LED screen are made with so many small pixel LEDs ,  less dead pixels , better effect . It is also according to the technology and original material , when you asking the price , make sure the original material is what you need .  it is better to be a brand company.


What is fine pixel pitch LED video wall ?

Fine pitch LED video wall meas the pixel pitch range below 2.5mm, such as 1.9mm, 1.8mm....0.75mm


1,What is LED Display? 
LED display is a flat panel display, which uses light-emitting diodes as a video display. An LED panel is a small display, or a component of a larger display. They are typically used outdoors in store signs and billboards, and in recent years have also become commonly used in destination signs on public transport vehicles or even as part of transparent glass area. LED panels are sometimes used as form of lighting, for the purpose of general illuminationtask lighting, or even stage lighting rather than display.

2,What is pitch size of LED Display?

Pitch size means the distance between the center of two LEDs, it is the most important factor for video quality:
Such as Pitch 6mm means the distance between 2 led is 6mm, it also means much more pixel in one square meter, 6mm will play very good quality video.

3,What is Soft or Flexible LED Display? 
The flexible LED curtain is a kind of LED display which is same to normal LED display,but the LED is mounted on DFR material which looks like window cloth,the biggest advantage of led curtain is 90% lighter and thinner than the traditional  LED display. Plz check the following photo,you will know  why we called it soft LED display.
here is the detail: 

4,How to find a good screen for your project? 
---You can choose LED Display according to the best view distance (The viewer and LED screen distance):
the viewing distance of a LED display is determined by 2 factors:
1. Pixel Pitch  (Important factor )
2. Screen Size
And as for most situation, pixel pitch plays the most important factor for a dedicated LED display. Here's the relationship between the viewing distance and pixel pitch, for your reference:

P2mm LED Display-------------------  Best Viewing Distance 2-24m
P3mm LED Display-------------------  Best Viewing Distance 2.5-25m
P4mm LED Display-------------------  Best Viewing Distance 3-28m
P6mm LED Display-------------------  Best Viewing Distance 3.5-40m
P7.8mm LED Display------------------- Best Viewing Distance 4-42m
P9mm LED Display-------------------   Best Viewing Distance 4.5-50m
P10mm LED Display------------------- Best Viewing Distance 5-55m
P12mm LED Display------------------- Best Viewing Distance 8-66m
P16mm LED Display------------------- Best Viewing Distance 9-75m
P20mm LED Display------------------- Best Viewing Distance 10-80m

5,What is LED? 
There are two types of LED panels: conventional (using discrete LEDs) and surface-mounted device (SMD) panels. Most outdoor screens and some indoor screens are built around discrete LEDs, also known as individually mounted LEDs. A cluster of red, green, and blue diodes is driven together to form a full-color pixel, usually square in shape. These pixels are spaced evenly apart and are measured from center to center for absolute pixel resolution. Pop LED type: SMD1921, SMD2020, SMD2727, SMD3535 

6,What is indoor LED display? 
Most indoor screens on the market are built using SMD technology — a trend that is now extending to the outdoor market. An SMD pixel consists of red, green, and blue diodes mounted in a single package, which is then mounted on the driver PC board. The individual diodes are smaller than a pinhead and are set very close together. The difference is that the maximum viewing distance is reduced by 25% from the discrete diode screen with the same resolution
Indoor use generally requires a screen that is based on SMD technology and has a minimum brightness of 600candelas per square meter (cd/m², sometimes informally called nits). This will usually be more than sufficient for corporate and retail applications, but under high ambient-brightness conditions, higher brightness may be required for visibility. Fashion and auto shows are two examples of high-brightness stage lighting that may require higher LED brightness. Conversely, when a screen may appear in a shot on a television studio set, the requirement will often be for lower brightness levels with lower color temperatures; common displays have a white point of 6500–9000 K, which is much bluer than the common lighting on a television production set.

7,What is oudoor LED display? 
For outdoor use, at least 2,000 cd/m² is required for most situations, whereas higher-brightness types of up to 5,000 cd/m² cope even better with direct sunlight on the screen. (The brightness of LED panels can be reduced from the designed maximum, if required.)
