An OLED (organic light-emitting diode) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound which emits light in response to an electric current. This layer of organic semiconductor is situated between two electrodes. Generally, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as mobile phones, handheld games consoles and PDAs.
There are two main families of OLEDs: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell or LEC, which has a slightly different mode of operation. OLED displays can use either passive-matrix (PMOLED) or active-matrix addressing schemes. Active-matrix OLEDs (AMOLED) require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes.
An OLED display works without a backlight. Thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD). In low ambient light conditions such as a dark room an OLED screen can achieve a higher contrast ratio than an LCD, whether the LCD uses cold cathode fluorescent lamps or LED backlight.
We now have the technology, to totally create software for post production to the streaming of video formats using OLED resolutions over fibre optics, creating a new breed of Internet TV in the living room, and computer systems and video cameras that can support a mini-broadcast station for the streaming of contents, a huge content explosion, where Internet TV broadcasting can be accessed anywhere in the world, where advertisers has a huge worldwide base of customers to market their products, Welcome to the world of Interactive Advertising. I am very familar because I was fooling around video formats more than 10 years back together with MP3 and compression technology, someone monitored my connections and my works that is how Adobe Flash was born but I did not even get a single cent, now I am going to set the new format but nobody will get anything without paying my dues. Tim Cooks even if you can build your retina screen to be as big as the OLED, you do not have the technology to tweak and calibrate the output of OLED for vibrant colors, I can make it beat retina screen anytime. LG is stupid to build such an expensive 55″ OLED TV without using sensors to compensate for the ambience lightings of the surrounding and using software to increase the vibrancy of colors of each OLED cells. I am working on a project, to intergrate the Opera Mini browser to support 3GP format player to support up to 640×480 resolution video player that can detect all screen types for tablets and mobiles for HTML 5 standards, even a higher OLED video player than will replace Flash Player for HTML 5 for 720p, 1080p, 2160p resolution video player and beyond. Part of the work will be HTML 5 coding methods to detect screen displayer, and use the appropriate player, I can easily invent a new video player, or use exsisting MP4 format to modify it to support the higher resolution, but most important of all, it must be like Flash player which charges very high royalties for it’s use.
