Undoubtedly, Samsung is the world leader in clamshell smartphones today, but it is interesting to know that the world's first clamshell smartphone was called FlexPai and was launched in early 2018 by Royole. The Chinese company recently presented its new research findings at the Display Week 2021 symposium (May 16-21, 2021, corresponding to May 26-31, 1400). Displaying a flexible 2.7-inch panel at the event, Royole claims to be the first in the world to have the technology to build a flexible display based on micro-LEDs. According to Royole, this display is compatible with current production processes in the industry.
As the name implies, micro-LEDs are smaller than OLEDs, which increases the distance between individual pixels. This more space can be filled with elastic materials and create such a unique feature for the display. In addition, the greater the distance between the pixels, the more space for light to pass through the screen, and thus, the screen will be clearer. Currently, Royole is showcasing a 2.7-inch model of this type of display with a resolution of 90 60 pixels, at the Display Week 2021 event.
Elastic electronic components are the pinnacle of flexible technologies and are made using electronic circuits with elasticity. Elastic displays are not only collapsible and rollable, but can freely accept a variety of three-dimensional shapes, including drag-and-drop, as well as convex and concave deformations. This could create new functions beyond the capabilities of current flexible displays, such as 3D folding to make more compact smart devices or using these displays to make domed or spherical objects.
Inspired by this new technology can be mass Created new form factors (requiring elastic properties) in various sectors of the industry - including health and fitness, sports, fashion and intelligent transportation. Royole has listed a variety of functions for this technology, such as smart clothing, improving health with devices tailored to the human body, and designing spherical and topographic instruments such as spheres or maps that, in addition to geographic information, provide details. Also provided historical and cultural. With this in mind, resilient electronics will revolutionize the way smart devices and devices are built and designed in the future.
According to Royole, some of the features of this micro-LED-based elastic display include: elasticity of up to 130% and convex curvature of up to 40 degrees. The screen has a density of 120 pixels per inch; The same density required for use as a laptop display. Micro-LED technology allows light to pass up to 70%, which is far more transparent than current OLED technology and can be used to build smart devices that require transparency (such as car glass or glasses). Sunny). For comparison, the screens used in LG transparent TVs transmit up to 40% of the light.
The study also suggests that the techniques used to develop stretch displays could be applied to the current process of producing flexible displays, including Royole's proprietary ULT-NSSP technology, which in turn can make the technology scalable. Accelerate toddlers. Needless to say, ULT-NSSP stands for Ultra Low Temperature Non-Silicon Semiconductor Process and means "non-silicon semiconductor process at ultra-low temperature". This advanced technology went into mass production in 2018 and was used to build the third generation of a fully flexible display called the Cicada Wing; The same display used in products like the FlexPai 2 clamshell smartphone.
Thanks to Royole's research findings, the company can take a major strategic step in the field of micro-LED solutions and excel in technological development and innovation in the highly competitive (highly competitive) electronics industry. As the Internet of Things accelerates, flexible electronic components (including fully flexible displays and sensors) are likely to become the dominant user interface, enabling interaction between people and future smart devices.
Finally, it should be noted that this is just the beginning, and in the not-too-distant future, other leading companies (such as Samsung) may overtake Royole. Another point to consider is that any company entering the field faces a serious challenge: convincing manufacturers to use these stretch displays, which are unlikely to be cheap. Source: Royole
