On April 17, Vidda's official Weibo asked netizens for help: "Is there a way to shrink the oversized power adapter?" Some netizens interpret this to mean that the new Vidda three-color laser projection product to be released in May may use a gallium nitride power adapter. It is understood that at present, gallium nitride technology is used in power adapters for high-end mobile phones and laptops, which has the advantages of small size and high power conversion efficiency, but the cost is relatively high.
In the picture released by Vidda's official Weibo, you can see that the power adapter on the left is the old projection, which is larger, while the power supply on the right is much smaller. Sharp-eyed netizens immediately recognized that the power supply on the right used gallium nitride technology, and were very excited to say that if Vidda's new product uses gallium nitride technology, it would be worth buying. At the same time, some netizens said that the cost of gallium nitride is very high, can it be held?
According to the data, gallium nitride (GaN) is a third-generation semiconductor technology with superior properties such as high frequency, high efficiency, high power, high voltage resistance, high temperature resistance, and strong radiation resistance. Compared with conventional semiconductor technology, GaN not only operates stably at higher temperatures, but is also more reliable at high voltages and frequencies, and can also operate more with less power consumption. GaN is not only widely used in cutting-edge fields such as defense and 5G communications, but also has been welcomed in the civilian market, for example, chargers and power adapters made with GaN technology can greatly reduce the size and make the appearance more beautiful, which is more in line with the aesthetic habits of contemporary young people.
Vidda is the pioneer of three-color laser projection, launching the world's first 4K three-color laser projection in May 2022, and quickly won a lot of praise from audio-visual enthusiasts for its high brightness and high image quality. Recently, Vidda revealed that it will launch a new three-color laser projection in May, which has also attracted widespread attention. If the new product uses gallium nitride technology, it is even more worth looking forward to.
