Today, with the rapid development of science and technology, the development of mobile phones is amazing. Face recognition, under-screen fingerprints, etc. These technologies refresh our understanding of mobile phones again and again. With the popularity of screens with 90Hz, 120Hz and even higher refresh rates, Fluency and visual effects must also have a qualitative leap in order to ensure a better sensory experience of mobile phones. Therefore, how to comprehensively improve the experience of the screen has become the top priority of mobile phone manufacturers.
For example, the recently released Black Shark 3 series gaming phones and OPPO Find X2 series phones have substantially improved the screen experience compared to previous products. The Black Shark 3 series mobile phones use 6.67-inch, 1080P resolution and 7.1-inch 2k resolution AMOLED displays respectively, and have a screen refresh rate of up to 90Hz, which truly brings an immersive experience to gamers; Find X2 series mobile phone screen size It is 6.7 inches, the resolution reaches the 3K level of QHD+ (1440*3168), and the ppi is as high as 513. While having a clear and delicate Display, it also supports 120Hz refresh rate and 240Hz sampling rate, known as the flagship of the senses! So why are these two mobile phone screens able to achieve an unprecedented stunning? This must talk about the fifth-generation visual processing technology under Pixelworks that they are also equipped with.
The fifth-generation visual processor and software launched by Pixelworks aims to improve the Display effect of mobile devices. While improving the hand, it restores the original intention of film and television art to the greatest extent and enhances the visual experience. The core technology of Pixelworks’ fifth-generation visual processing solution is MotionEngine™ technology, which is also an essential technology for high-quality display of mobile phones. Studies have shown that the maximum ppi the human eye can recognize is much larger in moving images than in static images, and MotionEngine™ technology addresses this unrealized visual quality gap in mobile devices.
As we know, although the refresh rate on the screen of mobile devices has been increased to 90Hz and 120Hz, there are only about 14 high frame rate movies in the 500,0003 movies in human history, and the rest are mostly 24fps, so the content itself The frame rate cannot match the high refresh rate development and demand of mobile phone screen display, and MotionEngine™ technology can insert frames to fill the gap between the content itself and the screen, while retaining the original intention of the content to the greatest extent. The leading motion prediction function of this technology can intelligently detect the motion content, analyze and calculate the motion trajectory of the object in real time, and then use the motion compensation function to improve the dynamic clarity of the motion scene and make the motion picture clearer and smoother. And no matter what content frame rate or mobile device refresh rate, the video content can be displayed accurately, and the original frame is maximized to ensure that the content details are more realistic without affecting the artistic effect. In addition, MotionEngine™ is content-optimized for movies, sports, streaming, and user-shooting videos, eliminating artifacts such as jitter, presenting more natural motion while preserving artistic original intent for an enhanced sensory experience.
All mid to high end TVs (100%) now have MEMC enabled by default, but most of the MEMC implemented on TVs are from 10 years ago. Now Pixelworks is bringing this exciting technology to mobile, but unlike MENC technology used in TVs, Pixelworks’ MotionEngine™ technology is not only focused on “interpolating frames”, but more on optimizing video while letting content Closer to real-world colors for an immersive visual experience.
Another great advantage of the Pixelworks 5th generation VPU is the ability to stay in HDR mode all the time. HDR video is known to provide higher definition and more realistic details, but one of the reasons why it is still not mainstream is that compared to SDR video, HDR video produces more jitter and requires higher brightness and greater contrast.
But with the development of HDR technology, HDR content is growing rapidly among popular content distribution sites. Take streaming media giant Netflix as an example. Netflix now has more than 200 HDR movies, compared with less than 10 3 years ago. In addition, Netflix has mandated that all new movies be shot in HDR, other internet streaming platforms are rapidly adding HDR capabilities, and with up to a billion colors, Pixelworks provides accurate, high-quality, certified HDR solutions for mid-range to flagship mobile devices Program.
In China, Youku is the “player” with the most HDR content among video websites, and it is also one of the video websites with the best experience in China. Pixelworks has already reached an agreement with Youku to jointly build a high-quality HDR video ecosystem for domestic mobile terminals. Youku uses the Pixelworks TrueCut™ platform to remake and upgrade existing video content to HDR, creating new video content for all Youku users. The TrueCut™ platform enables filmmakers to explore a wider range of artistic expressions for HDR and motion scenes than ever before, and it supports high dynamic range and high frame rate motion picture production, effectively avoiding unwanted flicker and jitter. This new video platform expands the creative options for visual storytelling across the screens of different devices, while ensuring the consistency of its artistic creation intent. Therefore, the application of the TrueCut™ platform on Youku has greatly improved the quality of HDR content. Great experience.
While HDR content has grown significantly, SDR content still dominates, again in the case of Netflix, whose 200 HDR titles still make up only 4% of its total library, and for Prime Video, this figure is less than 0.1%. In addition, according to data, 300 hours of video are uploaded to YouTube every minute, 99% of which are SDR, and with the increase of 5G users in the future, SDR source video will dominate the market, and Pixelworks’ Always HDR solution can convert SDR to SDR in real time. HDR effect for a superior visual experience for SDR video.
As part of Pixelworks’ auto-adaptive display technology, Pixelworks’ full-range DC dimming solves the problem of eye strain that AMOLED screens can cause at low brightness. And in all mobile viewing environments, brightness and tint are dynamically adjusted as lighting changes, enhancing contrast to maintain a more natural motion look, excellent color accuracy and clarity. In addition, by using the phone’s color temperature sensor, Auto Adaptive Display can also adjust the color temperature of the display to reduce blue light, especially at night, for continuous viewing and gaming.
Over the past 20 years, Pixelworks has delivered numerous image processing innovations to leading providers of consumer electronics, professional displays and video streaming services. Pixelworks simultaneously delivers a highly realistic visual experience and exceptional picture quality on all screens, from theaters to smartphones. Today, when screen technology has become the core competitiveness, Pixelworks hopes to lead the development of the next generation of visual technology through its excellent image processing technology and become a wind vane in the image display industry.
