You think it.
We light it up.

Welcome to the world of information displays

Every display we've ever built started with a question someone was brave enough to ask — "Can you make it do that?" And the honest answer, almost every time, has been yes.

We brainstorm the problem. We design around it. We engineer a solution, build it from scratch — and then we watch it light up exactly the way you imagined. We've been doing this since 1997.

Outdoor video walls. Fine pitch indoor panels. Token displays. Gold rate boards. Andon systems. Jumbo digital clocks. Environment monitors. If it needs to display something — you've found the right people.

Why choose CSPL

Not a reseller.
An engineering company.

Most LED display companies import from China, assemble and install. We go deeper — selecting PCBs, LED drivers, LEDs from MLS, Kinglight, Nationstar and Hongshen, and power supplies from Rong and Meanwell for 24×7 reliability.

And we go further still — integrating your display with your SCADA systems, environmental analysers, production line sensors and live data feeds. We've been doing this since 1997.
