Dell Venue Android Goes Official in CES 2011: No Pricing Tag Yet.

Dell Venue

The Dell Venue droid is observing its official worldwide launch just a week after its Korea-only launch.

Dell has formally announced its second Android 2.2 Smartphone of CES 2011, and it’s the candy bar Dell Venue we saw uncovered in South Korea at the end of 2010. The phone will run Android 2.2 “Froyo” with Dell’s own Stage interface on top to provide tools for organizing music, movies, photos, and other media and feature a 1 GHZ Qualcomm Snapdragon 8250 processor, along with a 4.1-inch AMOLED display with an 800 by 480-pixel native resolution protected by Gorilla Glass.

There’s also WiFi and Bluetooth, along with access to the Android Market. Dell preloads the Venue with Swype, RadioTime, ActiveSync and QuickOffice, along with their own Stage media app.

Until now, the Dell Venue device name has only been connected with Windows Phone 7 in the United States as the Dell Venue Pro. Nevertheless, now it has gone Android-running Smartphone. However, there are a few important things the Dell Venue does not have yet:

•    A release date,
•    A price tag,
•    And/or a carrier partner.

The Venue also sports an 8-megapixel camera with autofocus and high-definition video recording capability. The device has only 1 GB of memory but this is extendable to 32 GB via microSD card slot. The Venue also features 802.11 WiFi, Bluetooth 2.1+EDR, and assisted GPS—and there’s contradicting information about whether the Venue will feature an FM receiver.

Samsung Shows off Transparent AMOLED displays at CES 2011

Samsung is making headlines in the AMOLED and transparent AMOLED display sector in Consumer electronics show (CES 2011). It feels like AMOLED is gradually prevailing not only in cell phones but also in Notebooks now.

As I already mentioned a few days ago, Samsung Mobile Display, A subsidiary of Samsung Group, displays 14 and 19 inch transparent AMOLED Display for notebook PC’s or for other purposes at CES-2011. The Resolution is qFHD 960x540 pixel (78PPI) and the panel has about 40 percent transparency.

Last year at CES Samsung showed off a laptop prototype with a 14 inch semi-transparent AMOLED display. You could see the screen well enough, but you could also see through the screen to see whether your car keys are on the table or not.


This year, Samsung is carrying on flashing its transparent AMOLED technology. But instead of a laptop, the company gear up a couple of displays showing how the displays could be used for advertisement or other purposes which, frankly, make a lot more sense than transparent laptop displays. One of the display also happened to have a 19-inch display, which is the largest transparent AMOLED display available now.

Nevertheless, one thing is sure, that I pointed out in the previous posts about Low yield of AMOLED panels fabrication that this is going to be very costly when launched officially.

Count on the days when you are going to have this added in your list of commodities.

Super+AMOLED+Plus = Super-AMOLED Plus : What's New?

Well one thing is clear. Samsung does not have breaks in case of presenting novel display technologies in its latest cell phones and other gadgets as we saw in CES 2011. Not many people are familiar with the Word AMOLED, but Samsung have surpassed it to produce Super-AMOLED and now Super-AMOLED PLUS.

Currently, the story is like this: 












I have written too much about AMOLED and super-AMOLED and how they are made. SO, I am going to elaborate what actually Super-AMOLED PLUS is and if this new display type is going to make some difference or not.

Samsung Infuse 4G with Super AMOLED Plus

Samsung has demonstrated us two new high-tech Android phones this week at CES -- the Samsung 4G LTE phone for Verizon, and the Samsung Infuse 4G.  Both have had what they are calling super-AMOLED plus screen technology.  We tried to apprehend the differences between Super AMOLED and Super AMOLED Plus, because that’s the kind of thing I do.
 

Super AMOLED plus raises the number of sub-pixels by 50 percent - this simply means twelve sub-pixels instead of eight that renders the screen even more visibility in bright light, and should help make text and the edges of images crisper, while still keeping the lovely color that AMOLED displays provide.

So, we can say that this not a very new display rather it’s just tweaking with super amoled display technology to fine tune it (And to get a patent as well!).

The difference is slight so you actually have to confirm it in real time. There is video at the end showing a phone with super AMOLED PLUS display but the difference is not visible as it was in case of AMOLED Vs super AMOLED.

The Technical Reasons for AMOLED Panels Shortage.

The year 2010 is gone. We saw excellent gadgets appearing in the year 2010 with AMOLED or super AMOLED display that includes Nexus S, Galaxy S, and recently Cowon PMP Plenue D3 media player. But, at the same time we also heard a lot about shortage of AMOLED panels in the market that forced many companies including HTC to turn down AMOLED display for their cell phones and to revert back to other type of display like LCD, TFT or LED.
Working with Panels

What is the reason for AMOLED shortage ?.

 Low yield. In fact, very low yield.

Well, as far as we, the researchers are considered, there is a common perception among the researchers that AMOLED is a failed technology. Sit back and relax. Don't shoot at me! I said as far as the researchers are considered. Not the consumer's perspective.

And this is the reason for AMOLED panels shortage in the market. Every technology that is difficult to maintain at high yield rate is considered a failed technology unless the ways to improve the yield are discovered.

I am not going into the details about how the AMOLED panels are fabricated Cos I have already done it here. I am just going to tell you the exact reasons for AMOLED shortage.

If we consider at least 3 RGB sub pixels and keep in mind that at least 2 transistors are need at every pixel to produce light, one has to create atleast 2 into 4 million transistors to make SXGA (1024x1280) pixels display. at least 20 photo lithography steps are need to make TFT substrate for this.

20 STEPS. Keep in mind. Okay, so considering that the yield of each step is 95 % (I am too lenient by the way!) that gives the overall yield of TFT back plane only 32%. It makes the AMOLED panels not only difficult to make but also scarce enough to purchase for large scale production of gadgets.

And this is inherent. The only ways to bypass or escape this problem is:

1:   To shift the paradigm from traditional fabrication methods to some novel fabrications techniques

2:   Or to build too many plants to meet the world demands for AMOLED panels. and that's what Samsung is trying to do now.

Hope for the good.

Qualcomm to Invest US$1 billion in Taiwan

U.S. chipmaker Qualcomm Inc. is planning to invest about US$1 billion in Taiwan to build a factory for energy-saving color displays and to knock into the growing demand for e-reading devices, the Ministry of Economic Affairs (MOEA) said Monday.

The seven-hectare factory, which will be located in the Longtan site of the Hsinchu Science Park, will manufacture small and medium-sized handset displays using Qualcomm's low-power Mirasol technology, the MOEA said in a statement on its website.

The Mirasol display, mostly smaller than 5.7 inches, uses less power than similar sized thin film transistor liquid crystal displays (TFT-LCD) and active matrix organic light emitting displays (AMOLED) that are widely used on smartphones, notebooks and tablet computers.

The new plant is anticipated to create many jobs and fill out the industrial supply chain of advanced display manufacturing in Taiwan, the MOEA said.

The investment arrives on the on behalf of Qualcomm's joint venture in 2009 with local electronic component maker Cheng Uei Precision Industry Co., to form Sollink Inc.

How AMOLEDs and Super-AMOLEDs are Fabricated?

 How AMOLEDs and Super-AMOLEDs are Fabricated?

Well, how do you want me to justify this post?

I can go as deeper as you wish; In fact, I can write this post right from the core of clean room where everything is done regarding display panels fabrication taking benefits from my educational and research backgrounds. However, not every person reading this post is a tech guy. You might only be interested in seeing display rather than being curious about what is inside. However, I can bet seeing and praising a display is much better if you know at least something about how these displays are made. Apart from just general knowledge, it also helps to choose you a better display according to your needs.

So, in this post I am going to write how the AMOLED (active matrix OLED) are fabricated and  about differences in fabrication processes in AMOLED, and Super AMOLED display. 

The type of display your Smartphone has is typically described by an alphabet soup – LTPS, AMOLED, SLCD, Super AMOLED and TFT LCD all represent different technologies used in the production of display panels. Knowing what each type does, its benefits and drawbacks will help you understand just how good (or not) your phone is.

AMOLED  

AMOLED is actually ACTIVE MATRIX ORGANIC LIGHT EMITTING DIODE. So, AMOLED is just an OLED screen with the matrix being in Active state. Alternatively, let me go one-step further. AMOLED is an LED screen but it’s an organic LED instead of inorganic.

An active matrix OLED display consists of a matrix of OLED pixels that initiate light upon electrical activation that have been stuck or integrated onto a thin film transistor (TFT) array by using solution-processing techniques. Thin film transistor (TFT) operates as a series of switches to control the current flowing to each individual pixel. 

The first step is to make the backplane or TFT that is essentially very much similar to semiconductor fabrication root if Si is used as semiconducting material.

Ultra high purity cleaning of the substrate is the first step towards fabrication of AMOLED display.
After cleaning, doped Si precursor and SiO2 inslulating layers are applied on the substrate. Presently the plasma enhanced chemical vapor deposition (PECVD) is the only viable technique for this purpose to be used in production lines.

One important thing is worth mentioning here that nowadays Si is being replaced by amorphous indium-gallium-zinc-oxide because of its merits over Si. Samsung SDI’s development of a 12.1″ WXGA AMOLED highlighted the potential of this technology. The company used amorphous indium-gallium-zinc-oxide (a-IGZO) to replace silicon as the semiconducting layer of the TFT backplane.

Subsequently, Photolithography to define patterns, etching to create aspect ratios and doping to create transistors is done similar to traditional IC fabrications process. For AMOLED display, at least two transistors are needed for every pixel.

Afterwards, ITO (Indium tin oxide) which is a transparent material, is sputtered onto the TFT arrays that connects these arrays to the “outside world”.

Another cleaning step followed by buffer layer deposition by spin coating or solution processing makesthe backplane ready for further steps.

Next is the application of organic layers on the backplane. Light emitting polymers LEPs are used for this purpose. These can be applied by using spin coating or simple printing techniques also do the trick.
After application of organic layers, it’s time to make cathode and subsequent steps to finish the processing. Usually, if compared to LCD production, this stage starts from a thin calcium layer an Aluminuim foil to enhance conductivity and to act as a cathode.

AMOLED fabrication is complete upto this point. Its time to make the screen touch sensitive and to protect it from the atmosphere. 

A touch sensing glass panels is used if the display is intended as a touch screen display. Then the final transparent layer is applied to protect the AMOLED.

After encapsulation of the organic film is complete, the panels can be taken out of the clean room and packaging can be carried on for shipment.
AMOLED (Lower) Vs Super AMOLED (Upper)

Because of the fabrication process, AMOLED can be difficult to view in direct sunlight. AMOLED panels are typically three layers, the AMOLEDs, the touch-panel sensor layer made of glass and then the top glass protective surface with air in between each layer. The diffusion of light through all three layers causes the AMOLED light to be diffused and difficult to see.


Note that no anti reflecting layer is used in the fabrication of AMOLED panels that generated the biggest criticism for this display --- LOW VISIBILITY IN DIRECT SUNLIGHT.

Super AMOLED



So how to make the display crispy in direct sunlight? Simple. Make it super-AMOLED guys.

Samsung came up with a new strategy. The problem was the number of layers once the AMOLED fabrication part is complete. Samsung joined the touch sensitive layer and the top protective layer in one single layer that helped to eliminate the gap and air between those two layers. By reducing the number of layers and removing one air gap, light dispersal is reduced, making these AMOLED displays easier to see in bright light.

The “Active matrix” describes how each OLED is addressed or controlled. The alternative is a passive matrix display where rows or columns of OLEDs are addressed rather than individual pixels. As a result, AMOLED displays are not only brighter, use less power, they are also faster.

The Samsung i9000 Galaxy S series, including the Captivate, Epic 4G, Fascinate, and Vibrant, the Windows Phone 7 Omnia 7 ,  Nexus S and Focus along with many other phones uses super AMOLED display.

The following Promotional video from Samsung depicts the difference in AMOLED and super AMOLED display.

Watch out For Flexible AMOLED and Transparent AMOLED at CES 2011

Well, CES 2011 is alluring us. Every one of us who is interested in next generation display technologies is definitely expecting something interesting next week from CES 2011(Consumer Electronics Show). In addition, that is very justifiable because over the years, makers have chosen CES as an ultimate platform to highlight their state of the art products.

A few days ago, we posted about Flexible display at FPD 2010 and also showed you some pictures of a mobile with flexible display. 

Samsung is alive once again in news pertaining to their top-notch display technology that is very prototype kind of thing nowadays. Yeah, I am talking about flexible AMOLED display panels. According to Business wire, Samsung Mobile Display is going to unveil Next-generation AMOLED Displays at CES 2011.

Samsung Mobile Display (SMD) will be demonstrating leading edge, next generation AMOLED displays at Pepcom’s The Digital Experience! Press event during the Consumer Electronics Show, at the Caesars Palace Hotel on Wednesday, January 5th from 7 to 10pm.

Basically, two important AMOLED products are being showcased this time in CES 2011.

The first one is a 4.5-inch WVGA Flexible AMOLED offering world’s highest flexible display resolution. SMD is demonstrating a prototype of the most advanced flexible AMOLED display. Only 2mm thick, the 4.5-inch flexible AMOLED runs at a WVGA 800x480 resolution and can be rolled down to about one-centimeter radius. This new concept prototype provides a display resolution 4 times that of the previous most flexible AMOLED prototype in the industry.
Development of the 4.5-inch Flexible AMOLED prototype, designed for smart phone and tablet PC displays, is a major step on the road to mass production.

The second and even more interesting product in terms of capabilities and size is a 19-inch qFHD Transparent AMOLED for TVs and monitors that is going to be the World's first large-screen transparent AMOLED production prototype. SMD is demonstrating the world’s first large transparent AMOLED Display prototype, designed for use in applications from PC monitors to TVs.
This display offers 30% transparency whether turned on or off compared to other products that offer a mere 10% transparency.

Nevertheless, why do we need transparency?

Uses may include searching the Internet while watching TV, or watching TV on windows, including car windows for backseat passengers. Wow!

SMD will also be demoing a 14-inch qFHD transparent AMOLED for notebook PCs.
