StreamTV has been developing its technology for eight years and always seems to be getting ready for volume manufacture. We were told the same story again this year. They realize that they can’t reach their goal so have recently done some changes in the company. The Eindhoven team called SeeCubic, was working on their processing ASIC design, but this has now been assigned to a new more specialized team working in Silicon Valley. The SeeCubic team will return to their roots in new technology development, now headed by Bud Robertson. This team has designed some new optics for their panels to improve performance.
In TVs, StreamTV is working with BOE as the panel supplier. BOE has a 16M pixel 8K panel that Stream call “8K Lite.” What that means is that the panel uses sub-pixel rendering to achieve an 8K image. Some do not believe such rendering should be called 8K, so the “lite” monitor is used. Reportedly, BOE is also working on a more conventional RGB stripe 33M pixel 8K panel as well as a 16K panel. More pixels clearly helps with glasses-free 3D.
However, the sub-pixel rendering does add some new options for creating the multiple stereo views needed for the display, which the new optics seem to capitalize on. The result is that the 8K Lite panel can deliver 1080p resolution images with the extra pixels devoted to providing more depth.
As with all glasses-free 3D displays of this type, the processor must create multiple stereoscopic views that are viewed only from certain angles. In an auto-stereoscopic display, these angular 3D views are all displayed at once so that multiple people can see a 3D image. This angular control is provided by the lens assembly that sits above the panel. But creating all these views with a limited set of pixels reduces the resolution per view. And, the limited number of views need to be packed tightly together to form as smooth an image as possible with small head movements. To fill the full 180-degree FOV of the display, these limited views get repeated. And, the display must be optimized for a specific range of viewing distances.
On display was a 65” version of this implementation. Once you're in the sweet spot, the 3D can be quite good with small head movements not producing any discomfort. Larger head movements are not as good with a “swimming” kind of feel to the image quality.
As for production, the new design team estimates the new FPGA (not an ASIC until volumes are established) will be ready in Q3 or Q4’19. That means small volumes of the TV could ship by the end of the year. The decision to create an ASIC will be made at the end of 2019 potentially enabling lower cost solutions for 2020.
At a press conference in November, BOE and Stream TV announced their partnership and launched the first product, a 65" 8K "Lite" television. The new 27" PC monitor is the second product under the new partnership, with more in development.
