Screen displays have been becoming better and better as time progresses and as technology improves. We have seen it grow ever since the introduction of Apple's 'Retina' display, and has since grown to encompass insane screens with a 490ppi density, which is just astounding. 2014 looks like it will be the year of the displays, as plenty of smartphones are expected to have 'Quad HD' displays, like the Chinese Vivo Xplay 3S. Not only will screen resolution continue to increase, but the standards of color will grow as well. We have seen plenty of beautiful smartphone screens plagued by over-saturated or washed-out colors. Why did this happen? Well, the standard LCD technologies used in smartphones uses white LEDs with yellow phosphorus, and this combination, while useful for achieving a wide range of colors, cannot be balanced easily to bring out just the right amount of saturation. A relatively new technology that was adopted by the Kindle Fire HDX last year is the 'quantum dot', or a new style of LCD.
Quantum dots use blue LEDs and convert the light to the appropriate color and allow them to be highly saturated, but not overly so. They are similar in principle to AMOLED displays, but unlike AMOLEDs, they can be tuned and calibrated with extreme accuracy during the manufacturing process, which could give birth to phones with very accurate and pristine colors. We can also look forward to seeing new technologies that will increase our battery life, such as the indium gallium zinc oxide displays (IGZO) that allow for electrons to flow 10x more efficiently while reducing power consumption. Yay chemistry!
There is also the low-temperature polycrystalline silicon (LTPS) that has been adopted by the Surface 2 and the Kindle Fire HDX that allows for less power consumption, thus longer battery life. Ultimately, these changes are very interesting and could perhaps lead us into a new era of better looking, more power efficient smartphones. Of course, as will all new technologies, do not expect these to be cheap right out of the gate, but as the tech becomes more popular and more mainstream, we may hopefully see these technologies become the standard of the smartphone industry.
