De Franse fabrikant MicroOLED heeft een electronische zoeker (EVF) op de markt gebracht met een zeer hoge resolutie. De EVF beschikt over maarliefst 5 miljoen dots, wat beduidend meer is dan Sony OLED EVF’s van dit moment (2,4 miljoen dots, 1024×768). In zwart-wit kan de volledige 5,2 megapixel resolutie gebruikt worden (2560×2048), maar in kleur blijven er 1280×1024 pixels over – nog steeds enorm veel gezien het kleine schermpje.
Met een dot pitch van 4,7 microns zouden de pixels ‘gapless’ zijn (oftewel er zit geen ruimte om de pixels). De 24-bits kleuren EVF kan maximaal 16 miljoen kleuren weergeven. Het contrastratio is volgens eigen zeggen maar liefst 100.000:1, wat meer dan tien keer zoveel is als de Sony EVF’s. MicroOLED stelt tevens dat de EVF zeer weinig stroom verbruikt; slechts 0,2 watt. Het Franse bedrijf richt zich met haar EVF’s met name op professionele camera’s en camcorders, waardoor de kans klein is dat we deze OLED’s al op korte termijn in consumentenproducten gaan terugzien.
Desondanks is de toon gezet. Volgens Imaging resource zijn de dagen van de optische zoeker geteld. Wat denk jij?
MicroOLED introduces highest pixel density OLED microdisplay
MicroOLED’s new 5.4 mega pixel 0.61 inch diagonal microdisplay gives users SXGA resolution in full color at half the power consumption of competing products
Grenoble, France, January 27, 2012-MicroOLED, a maker of highly power-efficient superior image quality microdisplays for near-to-eye applications, today introduced a new 5.4 million pixel density 0.61 inch diagonal, low power consumption OLED (Organic Light-Emitting Display) microdisplay on silicon for applications demanding high picture quality, such as professional camera and camcorder equipment, night vision systems and head-mounted displays used in surgery.
The ultra-compact 5.4 million-pixel microdisplay with a sub-pixel pitch of 4.7 micrometres by 4.7 micrometres is the highest pixel density OLED microdisplay available today. By doubling the pixel density of comparable products, MicroOLED has eliminated the gap between pixels. With no black matrix present, the resulting image resolution is of the highest quality. This makes the 5.4 million-pixel 0.61 inch diagonal microdisplay most suitable for defense, medical and professional camera applications that demand sharp images with very smooth transitional tones.
High contrast (maximum 100,000:1) and high uniformity (96 per cent) also play key roles in picture quality. Depending on how one drives the OLED microdisplay, it can perform using as low as 0.2W, half the power consumption of other products in its category. MicroOLED achieves this low level power consumption even when the fully digital video input is embedded.
“We are really excited by the market potential of our new 5.4 million pixel density 0.61 inch diagonal OLED microdisplay that is superior in picture quality to any product in its category,” said Eric Marcellin-Dibon, CEO of MicroOLED. “This OLED microdisplay is already creating quite a stir among world leaders in imaging products who commend the high pixel density and the remarkable image quality. Moreover, the current trend in replacing optics with electronics components fits excellently with our ability to produce this exceptional picture quality in miniature format. We see many opportunities opening up in existing applications and new markets as a result.”
MicroOLED will market the 5.4 million-pixel density 0.61 inch diagonal microdisplay to address needs in three areas: head-mounted displays used by surgeons, where high resolution and quality of colors and contrast are a must; professional camera and camcorders, where picture quality is key; and night vision applications, where heightened contrast and uniformity enable defense and security professionals to improve the performance of detection and identification equipment.
The 5.4 million-pixel density microdisplay comes in full color (16 million colors), SXGA or monochrome formats (2,560 by 2,048 pixels), both with digital video input. It meets the standard environmental operating requirements for military applications. The new product builds on MicroOLED’s exclusive OLED patent technology that is recognized for its ability to eliminate defects common in other microdisplays, such as color non-uniformity or fixed pattern noise.
MicroOLED makes highly power-efficient microdisplays with superior image quality for mobile near-to-eye viewing devices used by consumers, medical professionals, and the defense and security industry. Through its microdisplays, MicroOLED makes it easier to integrate high definition in camera viewfinders, 3D goggles, head-mounted displays and other visual devices. The company’s exclusive high efficiency OLED (organic light-emitting diode) technology license provides significant advantages in high efficiency, contrast, uniformity and image sharpness making its microdisplays superior in quality to the full High Definition image in today’s flat screens. MicroOLED’s products also benefit from very low power consumption.
Founded in 2007, MicroOLED is a privately held company with headquarters, R&D and a new 300,000-unit production facility located in Grenoble, a renowned center of excellence in France for chipset and nanotechnology development. The company is led by a management team highly experienced in advanced technologies, including several years’ research & development in OLED technology from CEA-LETI, a leading European micro-and nanotechnology research center.
