Meta unveils laser technology changes:
Researchers from Meta have just created a screen prototype lit by lasers rather than LEDs. However, This technology allows the creation of very bright transparent displays adapted to augmented reality. Therefore, and could also be integrated into smartphones and holographic displays.
Most modern screens are illuminated by LEDLEDwhether by a backlight system (LCD, Qled, Mini-LED …), or thanks to pixels directly integrating the light source (OLED). However, the brightnessbrightness is not sufficient for outdoor use, or for screens transparenttransparentespecially as part of augmented realityaugmented reality. Nevertheless, To solve this problem, researchers from Meta have created a new ultra -fine display lit by laserslasers.
In an article published in the journal Naturethe researchers have a device meta unveils laser technology changes only two millimeters thick. Nevertheless, At the heart of it is a integrated circuitintegrated circuit Photonic (PIC). a chip combining thousands of components with different optical functions, powered by lasers. It is combined with a panel LCOSLCOS (crystals liquidliquid on siliconsilicon) five by five millimeters. with a full HD definition (1,920 x 1,080 pixels). Compared to a traditional LCOS screen, this approach reduces the thickness by 80 %, while increasing the range of colorscolors 211 %.
A technology intended for augmented reality glasses – Meta unveils laser technology changes
This prototype is very different from that unveiled a few weeks ago by other researchers from Meta. Stanford University. This is holographic and entirely opaque, being intended for virtual reality headsets. It is quite the opposite of this meta unveils laser technology changes new screen that researchers were able to test in augmented reality glasses.
However, this type of laser -based technology has its own faults. Researchers notably mention the shimmer of lasers. but there are certain techniques to reduce these problems that researchers have not yet explored. In addition. additional research will be necessary to integrate lasers operating in the spectrespectre visible to allow the production of massemassea technique already controlled for wavelengthswavelengths used in telecommunications. Apart from this problem. the manufacture of these screens is compatible with industrial production, which should allow it to be integrated fairly quickly into a new generation of augmented reality glasses. The peak designed by researchers could also be used in new types of devices. ranging from smartphone screens to fine holographic displays.
