Samsung new patent will bring a fully flexible display in our pocket

March 13, 2015 by Laur | 0 comments

Samsung, the world smartphone leader has developed a new patent for a new type of flexible display. The new patent is more than we saw at the Galaxy S6 Dual Edge and more than Galaxy Round. The new patent will make new Samsung devices more flexible and more resistant. With the new development, Samsung is maintaining the first position on the phones market and will release a new device maybe this year Q4 with a new style and a new flexible screen. At the beginning, the flexible display was blamed, but after Samsung released the three flexible screen devices( Galaxy Round, Galaxy Note EDGE and Galaxy S6 Dual Edge) Samsung started a new type of device. Galaxy S6 Dual Edge is an amazing device with two curved sides and a unique design. Actually if we read the reviews, Galaxy S6 is called the perfect phone.

The new Samsung patent presume that the next flexible device will be fully flexible. This means that next Samsung flexible device will have a metal frame fully flexible, a new type of battery fully flexible and also a new type of display, also fully flexible. With these three most important components, the new device will be able to be bended similar to a wallet without cracked display problems.

The image of Samsung patent shows us that the flexible battery is actually composed of many little batteries coupled between them this way could assure a full flexibility. As a new interesting thing at this patent is the main camera. It can be used for video conferences and as we know for video capture. The future device could feature two or more camera like this to be able to capture photos or record 3D videos and images.

The advantages of a flexible screen is everything you need in a movement life

March 6, 2015 by Laur | 0 comments

Touch screen is the interface between us and out smartphone or laptop or other touch screen device. Development of touch screen has killed the classic devices with buttons and made the life easier to us. But, after a while, the engineers thinks about a new type of touch screen, a flexible display, a bendable display, even a rollable display. This is a new era of devices when the cracked screen could become history. A classic touch screen display is made of layered thin films of iridium-tin oxide, a conductive material inorganic. This material is a very good electrically conductive and allow electrical signal to be sent from the touch zone to the edges of display.

The disadvantage of this materials is that is very easy to be cracked and the device won’t function normally. What can engineers can do for that? To make a flexible display without loosing any optical or electrical properties. And they made a new flexible hybrid film. Korean scientists A-Ra Cho and Soo-Young Park developed this new hybrid film.  The sol-gel technique is using acid wich corrode the metal from the device electronic components and the system can quite quickly. A method of acid-free is needed for optical thin-film application.

Cho and Park start with a combination of two organic materials “methyl methacrylate and 3-(trimethylsilyl) propyl methacrylate combined with trialkoxysilane”. Those chemicals are reacting with another two inorganic chemicals, tetraethyl orthosilicate, and titanium isopropoxide to synthesize hybrid layers reflective layers. This new hybrid film has been tested and compared to bare glass has a transparency of 96% and 100%. The production price is lower than a classic thin-films being produced at low temperature, without the need for high-vacuum.

The organic materials make the hybrid films to be more bendable and after more than 10,000 bending cycles the hybrid film scored less depreciation. But a little disadvantage of this new hybrid thin-film is that it needs more voltage and this could degrade the material. A new type of battery must be developed for the hybrid film to be used successfully into a flexible future application.

Two projects, two possible new modular devices. Choose Blocks vs Google ARA

March 4, 2015 by Laur | 0 comments

About the modular smartphone, there are a lot of good news. First time, Motorola talked about the modular phone and now Google is trying to revive the project. There are a lot of rumors about the Google Project ARA and its modular device. On the same idea, a UK team is working on a similar project called Blocks. Both ideas have small parts with different features and both projects are very appreciated on the market. The question is now, which will be the first modular device released? If we think logic, Google will release the first product, being a big company with many engineers and more resources.

Google ARA project-Yezz prototype

The Google Project ARA has been talked the first time after the acquisition of Motorola Mobility in 2011, and after the patent acquired from Modu, an Israeli mobile phone company founded in 2007. Modu is the first company which developed the first modular cellular device and held the record for the lightest mobile phone in the world. The real beginning of the project started on April 1, 2013 and Motorola shared pubic Project ARA on October 29, 2013 as a collaboration with Phoneblocks(a modular phone created by the Dutch designer Dave Hakkens).

Now, Project ARA has been shown at MWC as a prototype made by the low-cost manufacturer Yezz. The prototype could be launched a price about $200. Yezz is developing at the moment more than 80 modules for the Google ARA and the most interesting is that Yezz want to integrate a solar panel produced by Suncore, to one of the module to increase the device battery life. Toshiba is also involved in the development program for a camera module.
At the moment, Yezz developed two prototypes and is working on developing a new series of modules for the system. The base of the device is an endoskeleton where the other modules could be inserted into the device function. The modules could be a screen module, curved or flat, processor, camera module, GPS and Bluetooth module, storage and sensor module. The number of totally module placed on the endoskeleton is 11 including the display module. The modules are disposable into different sizes and could be swapped out and removed with magnetic claps. This feature offers the possibility to the final user to customize the watch with de desired modules.

Based on the Google Project ARA concept, a British team created a similar project for a modular smartwatch. The Blocks team wants to create a high-class smartwatch which with all their modules to be a super smartwatch. Blocks will be an Android device and will have the same features like a smartphone or a conventional smartwatch. Blocks can monitor the health, the fitness program, your weight and more. All the Blocks bracelet is actually composed of modules connected to metal jacks. The modules can be swapped and the watch could be upgraded or downgraded as the user wants.

Blocks prototype

Blocks concentrated the watch brain into the main modules which contain the display, processor, Bluetooth connection and the battery. For the Blocks modules will be a price around £20 to £40 per module. The modules can be camera, GPS sensor, heart-rate sensor, temperature sensor, additional battery and even a SIM card slot. For the Blocks display is in discussion three variants, one curved, one flexible and one normal flat display. The used technology for the display could be LED or for a better battery life could be E-Ink.
As a new technology, Blocks is a waterproof and dustproof device.
Both devices are interesting and could become reality in the near future. The only thing is to develop the modules and to miniaturize them to could make a thin device.
