Built To Last: Industrial Grade

Our taxi roof LED display solutions are designed and built with full consideration of taxi driving application scenarios where all weather proof is a must, thus every components employed are industrial grade to ensure the consistent performance in taxi driving environments, no matter it is hot, cold, with rain or snow. 

Friendly For CMS & IoT integration

Taking advantage of the open-source platform Android & Linux, we have optimized low level driver related code & SDK so that our customers & taxi advertising app developers can integrate their content management system as well as IoT sensors on plug & play basis.

High Ingress Protection

We design and develop this top quality taxi roof LED display with highly frequent mobility in the first consideration, thus, we make it totally waterproof and shockproof with a smart alluminium alloy frame,housing power module at the bottom, it ensures that the extra heat during operation will be giving off with the casing body automatically, while keeping elecrtrostatic prevention & lighting protection with solid reliability.

Rugged, Super light-weight and installation friendly

The whole taxi roof display cabinet is only 12kgs, 50% of the weight compared with unibody framed display. When it is so slim and light-weighted, it doesn’t compromise in ruggedness with proven laboratory & field based tests.

Thanks to the smart front access design and the slide-track rails, opeators could install or uninstall the device effortlessly.

Project Goal Recognition

We understand each customer has their own unique knowledge about industrial smart electronics solution, they may face different challenges, thus have different project requirements with different expectation.

Due to the above, the starting point of our job is to recognize the actual project target, helping our customers address the multiple aspects of the whole project, from installation, user experience to maintenance.


Our product team together with skilled engineers, project managers and customer success executives would engage directly with customer’s cross-functional teams, to obtain the full view of client’s challenge as well as the possible untapped pain, while presenting clients the existing solutions & case studies , thus clients could make better decisions about what they should buy.

Research & Design

We are able to develop the customized hardware and software precisely as per clients confirmed requirements.


We would quickly develop a concept-of-approval prototype to realize what clients need, in order to validate the requirements

Test & Trial

We would implement comprehensive testing via trial production, ensuring zero risk of mass-production failure.

Mass Production & Launch

Mass productions come as carefully planned, informed of our customers, with daily logging data shared so that shipment schedule could be reassured.
