FUTURE OF DISPLAY:



How do you want to watch in the future?.

By Mwaniki A. Ngari.

It is always exciting to look into the crystal ball, and the display industry is moving forward at an amazing pace in these years. The following are the five display technologies that could reshape the industry...

1. OLED
OLED technology is hard to ignore , it is already running in millions of mobile devices. OLED has the potential to change the entire display industry for years to come. OLED technology can also open up entirely new markets and enable manufacturers to create product categories that we cannot even imagine yet. Due to its ability to produce paper thin and flexible displays. OLED displays can become extremely thin, transparent and even bendable which will undoubtedly change our perception of display technology. OLED could make it into for example window glass or into textiles. OLED displays can become extremely rigid,too, and even serve as a light source in for example lamps – or just lighting mounted directly onto the wall or ceiling. Every major display manufacturer is researching OLED technology and analysts estimate that the OLED market will explode in the next 5-10 years. OLED has no inherent limitations to size and resolutions either, so it can even help enable gigantic living room TVs.

2. Tactile/Haptic
Touch Touch technology has probably been at the forefront in reshaping the display industry. Touch screens have grown from zero to everything in smartphones and tablets in a very short time period. It is almost impossible to find a phone today without a touch screen and it is hard to comprehend that all this started just 5 years ago when the first iPhone launched with capacitive touch technology and multi-touch.

So it is also natural to think about where touch technology goes from here. One of the most promising next steps is tactile – or haptic – technology. In a tactile touch screen you add a separate layer that can provide feedback to your fingers when touched. In other words; it can imitate physical buttons and textures dynamically on the screen surface; for example sandpaper or dirt. It happens dynamically and the device can make buttons or surface textures pop up and go away everywhere on the screen. For example, when you need a keyboard the screen can imitate physical keyboard buttons Tactile display technology is fairly mature already but we have not seen it adopted in any significant way so far. The obvious candidates are of course smartphones and tablets but tactile technology can also solve some of the most criticized elements of touch screens today; that they cannot be operated without looking. This could mean that touch screen TV remotes could become useful.

3. Higher Pixel Density
Smartphones and tablets have taken the lead in this trend, and higher resolutions are coming to your TVs and computer monitors, too.

Higher pixel density is dependent on smaller transistors. Transistors exist in all display panels and supply each individual pixel with an individual voltage level. Sharp's IGZO technology is an example of a display substrate that can enable much smaller and faster transistors, thus displays with higher pixel density. The really interesting part is that transistor technology not only benefits LCD panels but also plasma and OLED displays. That is why this is much more important than most people believe.

The trend towards higher-resolution displays is evident in pretty much every segment of the display industry. Within a few years even our PC monitors and TVs will benefit and take picture quality to a new level -even though resolution is not the only factor in great picture quality, to a new level – even though resolution is not the only factor in great picture quality, obviously.

4. Virtual Reality & Augmented Reality
Virtual reality and augmented reality have some common features but should also be considered separate concepts. Virtual reality is a "virtual" world -for example games and movies -and augmented reality is a concept where you add "layers" of visual information on top of our real world. Both visions involve display technology of some kind. One of the most recognized augmented reality projects right now is Google glass project where a small device projects visual information onto the user's eye. Google Glass is not an actual screen but rather a mini projector that sits in front of the eye

5. Glasses-Free 3D
3D TVs that require 3D glasses became the talk of the town after Avatar hit the cinemas. Since then, interest in 3D has fallen of a cliff. Viewers mostly in developed countries have no interest in wearing stupid 3D glasses while sitting in the living room sofa with friends and family. Toshibas has launched the first glassesfree 3DTV but the technology is still not ready for the mass market 3D is not dead but consumers and manufacturers have already turned their attention to glasses-free 3D displays. It will take many years to commercialize.
