Metal Oxide TFTs – Closer to Realization

Metal Oxide TFTs – Closer to Realization

In recent years we have seen flat screen TVs growing bigger and bigger and their capabilities continuously improved. Full high definition (HD) screen resolutions of (1920x1080 pixels) are now standard with many panel makers showcasing or announcing larger ultra-definition resolution screens. At the same time refresh rates are increasing, providing a better appearance of moving images and 3D TV.Consumers today can choose from a large variety of huge screens providing extremely crisp and detailed images at very high refresh rates. Most recently, large OLED TVs have started to reach the market. However, fabricating these high-performance displays represent a big challenge to the panel makers since they need to figure out a way to drive all these pixels integrated on very large areas with sufficient speed and low power consumption.

Novel Zero-Power Display Technology from Halation Photonics

Picture a future where your bathroom mirror doubles as an information resource, displaying the weather forecast and your daily agenda, and where your vision is precisely enhanced by tunable eyeglasses and windshields. This is a future that Halation Photonics aims to enable. Applied Ventures is proud to join Halation as an investor.The majority of mobile devices today use LCD screens. While these displays are certainly a technical marvel, next generation devices will demand higher efficiency displays that consume significantly less power.Unlike traditional displays that require a backlight and a constant power source, Halation’s multi-stable liquid crystal displays do not require any power to hold an image. In this video, Dan Sun, Halation’s chairman and CTO, explains Halation’s innovative technology and some of its applications.More on Halation's technology after the jump.

Witnessing a walk on the moon: Too bad we didn’t have 3D TVs!

With 15 years of experience in the Display industry at Applied Materials, I have witnessed firsthand the dynamic advances that have taken place in display technologies.  But as remarkable as these advances have been; the excitement and promise of displays are their ability to allow for the interaction of the shared human experience.Last Friday marked one of the great anniversaries in the history of live broadcast television, so I thought I’d take this opportunity to reflect on this moment in time and briefly describe the giant leaps made in display technology over the last 40 years.
Cutting-Edge LCDs: Your Metal Oxide Questions Answered [Updated]

Cutting-Edge LCDs: Your Metal Oxide Questions Answered [Updated]

[Updated February 13, 2013 because metal oxide backplane technology has improved since the original post was published. See question 7.]There has been a huge amount of interest and discussion around new LCD backplane technologies, particularly about metal oxide. Following on from my first post on the subject last week, I thought it might be useful to answers some of the questions I’ve been hearing most often.1. Amorphous Silicon (a-Si) has been the dominant transistor backplane technology for displays the last 20 years. Why are new technologies necessary?Changes are being driven primarily by the demand for higher resolution and faster refresh rates. The most important transistor parameter is electron mobility. Electron mobility of a-Si is very low (around 1cm2/Vs) and is at the edge of the physical ability to support high refresh rates such as 240Hz for high definition television. (Just in case you need a reminder, as this graphic shows, each transistor is basically an on/off switch that controls each red/green/blue subpixel and 240Hz refers to 240 switches per second.)

Cutting-Edge LCDs: What You Need to Know

The display industry is in the middle of one of the most significant technical transitions of the last 20 years and it is also mostly invisible to the average consumer. It has all to do with the advances taking place in transistors – the electronic switches that control the display’s picture, providing clarity and crisp imagery.Every pixel on your LCD screen is turned on or off by a transistor. The complete array of pixel transistors is known as a backplane, as you can see in the graphic. Clearly, the performance of the backplane directly affects the quality of the display for your TV, smartphones and tablet PCs. How fast the switch can be turned on and off refers to the refresh rate and the total number of pixels on the screen equals picture resolution. Today, there are three backplane technologies, which we call amorphous silicon (a-si), low temperature poly-silicon (LTPS) and metal oxide (MO). If you are buying a TV, should you care what transistor technology is in it?

CES 2012: 4K, Ultrabooks and Ice Cream Sandwich

The 2012 Consumer Electronics Show (CES) as usual was crazy big, and with a few key exceptions (Apple comes to mind; everyone flocked to Las Vegas to demonstrate the latest gadgets and gizmos including, the latest display products. These included mobile devices - both smart phones and tablet PCs; notebook computers and TVs.The goal of this post is to help you better understand industry terminology and highlight the latest products at this year’s CES enabled by Applied’s display technology.
CES 2012: TVs, TVs and More TVs

CES 2012: TVs, TVs and More TVs

I attended the Consumer Electronics Show (CES) in Las Vegas last week for the fifth straight year, and as always, it was dazzling. CES is where the major consumer electronics makers reveal the new products they are planning to release in the upcoming year. This year the major featured trends included new tablet PCs from a variety of makers, amazingly sleek and lightweight “ultrabooks”, more and better 3-D products, and interactivity through gesture recognition. However, this year the most stunning theme was large, beautiful TVs using a variety of technologies. Naturally, this is what interested me the most and in this blog post I’ll tell you why and about the trends for 2012.
