Portable displays have one major flaw: they need a cable to provide a smooth experience. A Japanese startup has developed its own technology, based on 5G, to connect an external screen to a smartphone, a PC, a game console… wirelessly and without latency!
Generally, whatever the technologies, it is impossible to connect an external screen to a smartphone or a PC without latency. There’s still some latency, but we’re talking about a smooth experience for work or play here. There is no shortage of technologies, there is Apple AirPlay, Miracast, WiFi Display… but these solutions are designed to broadcast videos, with which latency is not necessarily a problem.
A portable wireless display
When you buy a portable screen, the best solution is therefore to pass the video stream through HDMI or USB-C. This is where the Japanese startup InnLead Innovative comes in. They launched a crowdfunding project on the Kickstater platform to fund a product named Edge 2.5D. It’s a portable screen that connects via HDMI or USB Type-C, but can also be connected using the WirelessHD.
You can therefore connect this screen to a MacBook, a smartphone, a game console, a PC… without any wires. WirelessHD technology uses frequency bands analogous to those of millimetric 5G. The so-called millimeter waves operate in the frequency band between 24 GHz and 300 GHz. Here, it is not specified on which frequency band the WirelessHD works.
Through these waves mmWave over a short distance, from 1 to 25 m, high video rates can be transmitted with little latency. In any case, little enough not to be theoretically felt by users.
Note that to take advantage of the wireless connection, you need a transmitter mmWave, this limits compatible devices. Fortunately, the screen is sold with a transmitter in the form of a USB-C key. Finally, the wireless connection is possible up to Full HD definition at 60 Hz, certainly for speed reasons. They mention a maximum throughput of 7.5 Gbps, while uncompressed 4K requires 18 Gbps bandwidth.
The rest of the technical characteristics of this screen are classic, it includes a 10,200 mAh battery that would offer up to 4 hours of autonomy, with PowerDelivery 2.0 and QuickCharge 3.0 fast charging. The IPS LCD screen is touch-sensitive and is 15.4 inches diagonally, there is the possibility of having it in Full HD or 4K definition. The screen also includes stereo speakers and numerous connectors.
The available packs have prices between 400 to 600 euros, the project seems already financed. As we often explain, we advise against investing in a project at this stage of development. There is a high probability that the project will be delayed, or even worse, canceled. In any case, we can’t wait to see what the final product will be and if this technology can be democratized in consumer products.
