Apple Reveals Ongoing Development of Next-Gen OLED Displays

30a patent application
In early 2013 we reported that Apple had recruited a former senior researcher at LG Display, Dr. Lee Jeung-jil, who was in charge of researching OLED printing technology. So it's obvious that Apple is staying on top of this technology so that they can bring this to market when the time is right. To date Apple has several OLED inventions on record (One, two and three). Apple's current invention clearly acknowledges that OLED has better contrast ratios compared to LCDs while continuing to invent supporting technologies to correct certain OLED weaknesses and/or to fine tune the technology for specific applications or devices. Today's patent application relates to processes for realizing a variable optical path length for one or more microcavities in an AMOLED display. In the shorter term, we reported earlier this week that Apple placed orders for new power reducing Oxide LCD Displays for next year's iPad Air.

Apple Invents New Methods for Improving AMOLED Displays

30a patent application
On May 8, 2014, the US Patent & Trademark Office published a patent application regarding methods for improving AMOLED displays. Today's patent pending invention covers new methods for greatly improving gray level controls that improves overall color. While some may not take Apple's work on AMOLED too seriously because of disparaging comments that Apple executives have made over time, think again. While Apple's CEO was talking at the Goldman Sachs conference held on February 12, 2013 he stated that "If you buy things online, you should think twice before you depend on the color of the OLED display. The Retina display is twice as bright as an OLED display. Some people use OLED displays, but the color saturation is awful." Yet while Apple's CEO was downplaying OLED publicly, the fact is that Apple had just recruited a former senior researcher at LG Display to work on OLED display technology a week earlier. Apple's executives downplay current OLED displays available from competitors, but that doesn't mean that Apple can't vastly improve upon it for future products that use flexible displays that are primarily OLED based.

Apple Reveals New Multitouch with FTIR and Capacitive Sensing that Might be used for Advanced On-Screen Gaming Controls

1. cover
On April 3, 2014, the US Patent & Trademark Office published a patent application from Apple that reveals their work on next generation multitouch technology that uses FTIR (Frustrated Total Internal Reflection) and capacitive sensing. It's much like the technology that Microsoft calls PixelSense. It's a technology that could sense different pressure levels which could be used for an on-screen gaming controller. If you want speed, just push harder on the display and the car will accelerate. It may also be used for future virtual reality applications. With Apple's recent acquisition of PrimeSense, Apple definitely has something big that they're working on for 3D gaming and/or other advanced applications.

Apple Invents Techniques for using Sapphire on iDevice Displays

30. Patent Application
It was reported yesterday that GT Advanced, Apple's manufacturing partner for its new sapphire glass plant in Mesa, Arizona, began advertising job openings at the new plant that will produce sapphire materials that will cover iDevice cameras and Apple's Touch ID Home Button feature. In March we were first to note that Apple may shift to sapphire crystal for future iDevice display covers. Then in September 2013 we posted a report about a new fusion process for adding a sapphire laminate layer to future iDevice cover glass as well as wearables. In December 2013 Apple revealed future iDevices could use flexible sapphire displays created with a sophisticated liquid-metal process. In today's published patent application, Apple once again confirms that iDevices will use sapphire for future iPhone displays and beyond.

Apple Invents OLED Displays with Integrated Thermal Sensors

30. Patent Application
In February during the Goldman Sachs Conference, Tim Cook described OLED displays as awful. "If you buy things online, you should think twice before you depend on the color of the OLED display. The Retina display is twice as bright as an OLED display." Cook added that "Some people use OLED displays, but the color saturation is awful." While Apple's CEO downplayed OLED, the fact is that Apple has a great number of patents covering the improvement of OLED displays and in February they recruited a former senior researcher at LG Display to work on display technology. In today's patent application published by the US Patent and Trademark Office we learn that Apple is working to integrate thermal sensors into displays in order to control color. The advantage to OLED that Apple may not be able to ignore is that they can be flexible for future wearable computers like a computer band or iWatch.
