The futuristic lighting
Before we discuss the Future of OLED Lighting, let us first look into this technology, and what it can do. OLED, a light emitting diode emits electroluminescent layer in response to an electric current. This layer of organic semiconductor material is situated between two electrodes. Generally, at least one of these electrodes is transparent. The family of OLEDs is basically divided into two main categories: those based on small molecules and those based on chain of molecules called polymers. Adding mobile ions to an OLED creates a Light-emitting Electrochemical Cell or LEC, which has a slightly different mode of operation.
OLEDs can be used in various places and applications such as in television set screens, computer monitors, small, portable system screens such as mobile phones and PDAs, watches, advertising, information, and indication. OLEDs are also used in large-area light-emitting elements for general illumination.
OLED displays work without a backlight. Thus, it can display deep black levels and can be thinner and lighter than liquid crystal displays (LCDs). In low ambient light conditions such as dark rooms an OLED screen can achieve a higher contrast ratio than an LCD, whether the LCD uses either cold cathode fluorescent lamps or the more recently developed LED backlight. Due to their low thermal conductivity, they typically emit less light per area than inorganic LEDs.
What is OLED and what’s so great about it?
Here are few of the advantages OLEDs have over other TV screen technologies:
- Blazing fast response times
- Wide viewing angles
- Exceptional color reproduction
- Extremely high Contrast levels
- High Brightness
The nature of its technology lends itself to extremely thin and lightweight designs along with the ability to use it in a variety of different applications. OLED is the holy grail of TV Display technologies!
Let’s discuss how OLED display works and what is its principle?
In OLED technology, a layer of organic material is stacked in between two conductors (anode and cathode), which are then again sandwiched in between a glass top plate (seal) and a glass bottom plate (substrate). When electric current is passed through to the two conductors, a bright, electro-luminescent light is produced directly from the organic material.
Organic light emitting diodes have been receiving a lot of attention over the world as a new type of display technology. OLEDs have many advantages over conventional display technologies
