Whereas the Apple Imaginative and prescient Professional VR headset has a much-hyped decision of three,386 PPI (pixels per inch), a brand new expertise greater than doubles that determine. It was created by Los Angeles-based startup Q-Pixel, and it might revolutionize the world of video shows.
As most readers will likely already know, the pictures on present OLED and MicroLED screens are made up of particular person image components known as pixels.
Every pixel in flip consists of three side-by-side microscopic LEDs often known as subpixels. Certainly one of these is crimson, one is inexperienced, and one is blue. By various the depth of every subpixel relative to the others, it is potential to make the whole pixel tackle any shade within the rainbow when considered by the human eye.
One limitation of the expertise lies in the truth that as a result of every pixel have to be massive sufficient to accommodate three subpixels, the display decision is not as sharp as it could be in any other case. Whereas this downside could not matter that a lot with TVs or laptops, it turns into a difficulty with VR headsets, wherein viewers’ eyes are fairly near the show.
Moreover, manufacturing and arranging all the subpixels – throughout the tens of millions of pixels that make up one show – is a really fiddly, labor-intensive course of. For that reason, merchandise with ultra-high-definition shows are typically fairly costly.
That is the place the Q-Pixel tech is available in.
Placing it merely, the system replaces the three subpixel LEDs with a single polychromatic LED. On the coronary heart of that microscopic LED is a gallium nitride semiconductor which emits both crimson, inexperienced or blue gentle relying on the utilized voltage.
In a latest demonstration of the expertise on the Society for Info Show’s annual symposium, Q-Pixel unveiled what it claims is the world’s highest-resolution active-matrix shade show. Measuring about 1.1 by 0.55 cm (0.4 by 0.2 in), the display boasts a decision of 6,800 PPI – that works out to about 3K by 1.5K pixels.
In response to the corporate, the meeting course of for its shows is far easier and simpler than what’s presently required for ultra-high-def OLED and MicroLED shows. Moreover, like different MicroLEDs, Q-Pixel’s are claimed to supply a sooner response time, greater brightness, longer lifetime, and superior vitality effectivity as in comparison with the LEDs utilized in standard shows.
And as an fascinating aspect word, scientists at MIT have taken a unique strategy to the entire MicroLED decision factor, by stacking the three subpixels on prime of each other.
