17 steps to choose LED display for virtual production
How to choose a digital LED wall screen display set for Virtual ProductioN
Choosing the best LED display screen for Virtual Production is simple but is a long process.
If you are looking to build a Virtual production studio and you are looking at options to buy LED wall display sets for the studio then you know that quantity will be big and so will be the budget.
If Budget doesn’t allow you to buy the most expensive LED wall out there then this page will help you to know what is important to understand before placing your order.
THE 100 MOST IMPORTANT ELECTRONIC COMPONENTS TO LOOK AT PRIOR TO BUYLED SCREEN DISPLAY FOR VIRTUAL PRODUCTION.
There are ways to reduce the budget of your led wall screen display without having to compromise on the quality of the wall screen in-camera. Here we will list what are
We will start by explaining technical knowledge about the core components and performances of an LED screen display. Once those technical knowledge are understood, you will need to go through a number of tests to ensure the performances of the product in front of a camera are as expected.
Those tests are to ensure the LED screen display would work in many different situations and configuration. There are more than 4000 factories specialising in LED wall display most of them are located in Shenzhen.
Those 100 electirc components impact on the performances of the screen in-camera but also it impact on a lot of the budget.
Each factory propose an average of 10 products so potentially 100ds of product options to choose from in each factor. Our team is here to help to have a better vision on what is the impact of each electronic components to enable you to compare apple to apple.
17 STEPS TO CHOOSE LED DISPLAY FOR VIRTUAL PRODUCTION
Step 1 : LED Lamp Brand
The name of the brand of each dot pixel that your screen will be composed with.There are a number of LED lamp brands on the market from low end local Chinese brand to high end expensive Japanese and LED brand. Make sure to pick the one that will fit your end customer requirements.
Step 2 : Serie/Type of encapsulation
Step 3 : COLOR GAMUT
Color gamut is the entire range of colors and tons
achievable by an imaging system. More
specifically, the portion of the color spectrum
that can be reduced when transforming from
RGB colors to CMYK colors.
Step 4 : Sending card/Processor
Step 5 : WIRE CONNECTION
- Golden wire: Higher price but better transmission, encapsulation and stability,
It has the most mature welding
- Copper wire brings cost reduction yet welding process is more affected then the failing rate and dead pixel ratio increased
Step 6 : DRIVER
Driving IC is an integrated electronic component,
which is mounted in the surface of PCB
(back side of module), the driving IC receives
and sends data signal and power signal to LED
lamp through integrated circuit on PCB.
Computer of each PCB dictates the performances
of each LED screen.
Step 7 : MOSFET
The MOSFET (Metal Oxide
Semiconductor Field Effect Transistor)
transistor is a semiconductor device
that used for switching purposes and for the amplification
of electronics signals in electronic devices.
Step 8 : REFRESH RATE
Refresh rate is the number of times per second (written in hertz, or Hz) a screen refreshes its image.
It’s directly affect the LED display’s performances. The higher the refresh rate the more stable and clearer the display image and a smaller impact on the human eyes. The lower refresh rate will get the bigger flicker and Jitter of the display image, and faster get fatigued to human eyes.
Step 9 : BRIGHTNESS
Brightness is measured by using nite or candelas
per m2. The higher the luminosity level, the
higher level of brightness. Screens with higher
brightness are pricier and use more electrical power.
Hence, it is important to choose a screen with the right
brightness for your needs, so won’t pay
more for something that is not necessary.
Step 10 : GRAYSCALE
Grayscale indicates how many intensity levels
from the darkest to the brightness can be
displayed on an LED display.
Step 11 : SCAN
The scan = Time multiplex.It frame rate is 60,
which mean every 1/60sec will refresh a picture
The static LED only control one LED in 1/60s
If the scan is 36scan LED will control 36 LED
in 1/60s.The lower
the scan rate the better the performance and
The more expensive it will be.
The smaller the pitch, the greater the number o time-multiplexing.
1-35 scan = lower scan
36 – 64 scan = higher scan
Step 12 : LED PROTECTION
Resin or proxy lay to project the LED in order
to prevent Dead pixel
Step 13 : CABLING TYPE
Quality of the cabling that connects LED.
The better is the quality the more stable
the screen will be. All in order to avoid a black screen
during a live concert for example.
Step 14 : POWER SUPPLY
The unit of power supply that transform High voltage to low voltage
Step 15 : RETAL PRODUCT
All feature to enable : Fast fit-in and fit-out, shorter installation time and touring the product on multiple location
Step 16 : TYPES OF RECEVING CARD
The receiving card and hub card is the control
system of the LED screen, Usually, sending a card is installed on the
PCI-E slot of the control PC, collects and transfers data to LED screen.
Receiving card is installed in each cabinet
of LED screen, receives the data from the sending
card and runs the LED screen.
Step 17 : HDR
Increased contrast and luminance ranges
Expanded range between darkest and lightest parts of image
allows for a greater level of contrast.
Wider and finer color spectrum allows for smoother color gradation.
Image comes closer to what the human eye can see, allowing the picture to pull the viewers into the scene.
LED screens don’t necessarily need to work with high-end components, and state of the art driver IC’s but for Virtual production there is a level of quality not to go under otherwise the compromise on the quality will be seen on the screen.LED panels are capable to display visuals from 10-bit to 16bit even 22bit HDR with the image boost feature from Novastar. By selecting a wide range of selected suppliers, Street Co is able to provide wide range of LED display solution that can both fits:
Those premium LED batches from carefully selected suppliers can reach more than 90% of the color gamut on a rec2020 target. And last but not least for this type of application, Street Co LED panels are able to work with higher frame rates. Due to new high frame-rate options in the control system software, Street Co’ LED can propose LED panels that can reach up to 144 frames per second.Essentially, the lower is the scan rate, the better the performances, the higher the price, the higher brightness.Our team is here to help and guide you through this complexe technical spec in order to choose the best LED option that will fit your budget.
The most expensive LED screen display products aren’t necessarily required for Virtual Production LED screen sets. Some specific electronics are necessary but they don’t have to be the most expensive products.
