Factory China

We are a middle sized Led Display Manufacturing Company in Shenzhen China.
Pioneering in outdoor small pitch products. We earned the name to be the best for small pitch outdoor solutions.

Rocketsign is a brand of Darklight.




Building 44 Fuming Industrial Zone Pinghu Street Longgang, Shenzhen, China .


The name Rocketsign started 3 years ago. We started brainstorming a new name that follows our vision. Since most customer talk with us that making led screens is not rocket science which made us come up with the name. (which we changed a little about the name to fit in).
The reason of the name is also that we want to prove the world that it can do rocket science, inventing new led technology is extremely hard since we have to compete with the very big companies. So we focused everything on small pitch outdoor and went for it.
But we made it possible and started with the P4.8 outdoor technology to be used in Rental in 2014, we were far ahead of all the competition and won the high technology award for it. We are pioneers in small pitch outdoor led screens and were always at least 1 year ahead of all the competition.

Because our led screens products are unique, our small pitch outdoor led technology beats the competition and can give you many new solutions possible. Which means if you are even working already with a competition it could always be very interesting for solutions that the competition can not supply. We are simply the best for alternative solutions which can help you to increase your market and providing solutions to your customers.

Our best product would be all the screens that are using the M.U.S (Metric Unit System) Technology.
Which are made with 250x250mm led modules. With the Metric Unit System Technology we can achieve an extremely high outdoor led display resolution which is determined by the pitch of the led. At the moment our P3.2, P3.9 and P4.8 are extremely popular because of the perfect viewing angle, detailed finishing  when you get close to the display, it still looks extremely nice because of the high uniformity. (which competition can not compete)

Everyone will compare the led screen factories. Well we can tell you if it is for outdoor small pitch solutions that we are probably the best of the whole market at the moment. We focus so hard on that technology that we will not lose our focus on doing everything. It is very important to focus to be the most professional as possible.

We make our own moulds and design which lies the secret of our technology to make this happen.

We did OEM for many years. Once we want to grow we needed our own brand and product line.
So we focused our resources on small pitch outdoor, used for rental and fixed installations.

One of the business owners has 20 years of experience with plastic moulds for led modules and also owns a plastic mould factory. Because of his experience we could easily add the necessary technology to make an outdoor small pitch led screen.  Our engineerings team is extremely professional and can make the difference. Ofcourse it is after many testing before we could fully improve the product.
