A Concept AMOLED Phone to Save Battery Life

As the screen gets bigger and bigger, Battery life becomes weaker, So making just screens bigger and not rethinking about battery is a fatal mistkaes. Makers take care of this fact but the difference is high. Do you remember the days when NOkia 1100 could run almost a week on a single charge. We need to rethink about our startegies in making battery cope better with big screen phones.

Concept phone to save battery life in standby mode.


This idea of second life mobile phone is mighty creative that could help to save battery life to a good degree.

this concept phone incorporates a double display. When in active use, the AMOLED screen powers up in all glory and in standby mode the E-ink display gets active. This essentially means that the E-ink uses very little energy and the degree of transparency of the display shows how much battery is remaining. The more transparent the display, the less battery remaining.

I like the idea behind the concept and its transparent vaura, but I guess its more targeted to a specific set of users who keep forgetting to put their phone on charge.

As a remedy (rather power-saver-option) the phone incorporates a double display. When in active use the AMOLED screen powers up in all glory and in standby mode the E-ink display gets active.

Polymer Light-Emitting Diodes (PLED): A Promising Display Technology of the Near Future

HPolymer light-emitting diodes (PLED) that uses  light-emitting polymers (LEP) are the next generation display types that promise excellent results as well as cost and power efficiency. Moreover, PLEDs are very easy to fabricate a large area panel that facilitates the production of large display devices like TVs. Acording to PLED has shown their vision in taking LED technology to a new level.

Display industry is evolving at a very high rate. Researchers and Engineers are the backbones of this industry that are actively giving new ideas for future display industry. The most common types of displays include CRT, LED OLED, AMOLED, S-LCD, and Super-AMOLED etc. Super AMOLED is currently in very much active phase and Samsung as well as some other companies are shifting their products Display paradigm towards super AMOLEED screens. However, it is not easy to produce Super AMOLED display panels. Manufacturers, keeping in view the trends of industry and users, always focus alternatives.


Some Technical details of PLEDs
The story began in the Cavendish Laboratory of Cambridge University in 1989, when it was discovered that 'organic' LEDs could be fabricated using conjugated polymers.

Polymer light-emitting diodes (PLED) or light-emitting polymers (LEP), involve an electroluminescent conductive polymer that gives off light when attached to an external voltage. They are used as a thin film for full-spectrum color displays. Polymer OLEDs are quite efficient and require a relatively small amount of power for lighting. Polymers can be processed in solution, and spin coating is a simple method of depositing thin polymer films. This method is more suited to forming large-area films. Classifiable polymers employed in PLED displays include derivatives of poly(p-phenylene vinylene) and polyfluorene. Whereas, Substitution of side chains onto the polymer backbone may determine the color of emitted light or the stability and solubility of the polymer for performance and ease of processing.

So we can say that, in comparison with OLED, PLEDs have relatively simple structure, with the light-emitting polymer (LEP) layer combines the host, emitter and charge transport affairs in a single solution-processed film of the device. 

 According to Cambridge Display technologies:
One of the most electrifying developments in the display industry in the last 15 years has been the discovery and development of polymer light emitting diodes (P-OLEDs).
Littelfuse and Sigmaalgrich are already providing materials and substrates for Research of PLED.
