Low power consumption continues to gain further growth, especially in the mobile application market, such as music/video players, viewfinders for cameras and camcorders, and consumer video glasses. There are currently many micro display technologies competing in this market. (especially micro-liquid crystal technology) technology has matured through the increasingly popular large-screen TV and monitor application market. Reflective display technologies, including digital light source processing technology DLP and liquid crystal liquid crystal technology (LCOS), are particularly advantageous for projection systems, and they have been implemented in a variety of popular applications over the years and have made significant progress. Radiation display technologies (such as O LEDs , or organic LEDs) are relatively new, but have been able to compete with LCD and LCOS technologies for price and performance. In addition, because they are relatively early-stage technologies, they have more room for improvement in the future.
Oled displays can use small organic molecules or polymers. From the perspective of the entire display market, soluble luminescent polymers have major advantages because they can be easily precipitated into solutions on display substrates without the need for a temperature controlled vacuum environment (eg by spin coating or inkjet printing). ). Compared to small molecule OLEDs, polymer technology allows for the manufacture of larger screen size displays because it does not require the shadow mask required for vacuum deposition processing. Polymer OLED (P-OLED) displays can also operate at lower voltages and consume less power than small molecule based displays.
P-real development in the early 1990s, when the UK-based startup Cambridge Display Technology (CDT) developed a separate luminescent polymer from Cambridge University, which is located at the center of the P-OLED display. Fluorescent material.
Today, PO LED technology can be used to make displays of all sizes and performances, from simple monochrome displays to full-color graphic displays that display dynamic video. According to NanoMarkets LC, a leading industry research company, organic electronics technology is rapidly moving out of the lab and into practical applications. Markets for display products such as OLEDs, organic thin film transistors and other organic materials will grow significantly from $1.4 billion in 2007 to $19.7 billion in 2012 and continue to generate $34.4 billion in revenue in 2014. By 2012, the OLED industry (including display, signage and lighting applications) market is expected to grow to $10.8 billion.
Microdisplays (displays integrated with drivers and control electronics on a single silicon substrate) are currently gaining momentum. Microdisplay applications fall into two broad categories: projection and near-eye. P-OLED microdisplays provide the most advantageous near-eye microdisplays and can be subdivided into two main sub-categories. In the first subclass, the microdisplay module is embedded in the product and then lifted to the front by hand, such as electronic viewfinders for video cameras and digital cameras, as well as for specialized systems (such as night vision goggles, electronic duals). Electronic viewfinder for telescopes and telescopes. In another subclass, the microdisplay module is placed in front of the eye with a hands-free structure, or worn on the head like a pair of video glasses (such as a head-mounted display of a personal multimedia player) that allows viewing on a mobile phone. TV and play games on the road.
The latest representative of P-OLED microdisplays for these applications is the eyescreen ME3204, developed by MicroEmissive Displays (MED) in Edinburgh, UK, which provides a complete digital microdisplay solution with high electronic and optical integration. degree. The ME3204 delivers first-rate image quality and ultra-low power consumption, delivering outstanding QVGA resolution (320 x 240, 230k pixels) image quality with diagonal pixel array spacing of only 0.24 inches (6mm).
Radial Polymer Organic Light Emitting Diode (P-OLED) technology without backlighting, and display driver electronics and digital video interfaces integrated on the ME3204 allow the ME3204 to integrate directly into a wide variety of systems and enable product designers to Develop smaller and lighter products. The Eyescreen ME3204 is supplied with an integrated wire collection.
Low power consumption
The key elements of the microdisplay are power consumption, image quality and longevity. Power consumption is a problem. It affects video glasses more than the viewfinder because the viewfinder is only one of the active components of a handheld device, and in video glasses, the microdisplay is basically the main active component.
In digital cameras, the LCD display | display device is probably the most expensive part of a single component. This is why the advice often given is to turn off the LCD display to preserve battery life. For example, a typical 320 x 240 pixel LCD display may consume 300 or 400 mW of power, while a typical LCD microdisplay consumes less than 200 mW. However, a comparable P-OLED microdisplay consumes only 50mW, so using a P-OLED EVF instead of an LCD display or LCD microdisplay is a significant improvement over battery life.
One of the reasons for this phenomenon is traced back to the basic characteristics of display technology. LCDs require a very bright backlight because they are transmissive and inefficient. In contrast, P-OLEDs themselves emit light and are very efficient.
Power consumption is a very big problem in video glasses, where the microdisplay is the single most power consuming component. The 50mW power consumption is equivalent to the theoretical 30-hour battery life of a basic AA battery. An LCD microdisplay is maintained for less than 9 hours. (small soup)
