What is organic electroluminescent display?
An organic light-emitting diode (OLED or organic LED), also known as organic electroluminescent (organic EL) diode, is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current.
What are electroluminescent displays in computer graphics?
Electroluminescent Displays (ELDs) are a type of flat panel display created by sandwiching a layer of electroluminescent material such as GaAs between two layers of conductors. When current flows, the layer of material emits radiation in the form of visible light.
What organic material is used in OLED?
polyfluorene
One conducting polymer used in OLEDs is polyaniline. Emissive layer – This layer is made of organic plastic molecules (different ones from the conducting layer) that transport electrons from the cathode; this is where light is made. One polymer used in the emissive layer is polyfluorene.
How does an electroluminescent panel work?
Electroluminescent panels are a capacitor where the dielectric between the outside plates is a phosphor that gives off photons when the capacitor is charged. By making one of the contacts transparent, the large area exposed emits light.
What is electroluminescent backlight?
EL (Electroluminescence) backlighting is also called an ELP (Electroluminescence Panel). This type of backlighting is a technology that uses colored phosphors, not heat, to generate light and can be added to many LCD technologies.
What is electroluminescent material?
Electroluminescent materials (ELs), such as zinc sulphide doped with copper 1, emit light when an electrical current or voltage is applied to it, or when subject to a strong electric field. Such materials are generally inorganic phosphors, or organic semiconductors, such as quartz.
Is OLED really organic?
OLEDs are organic LEDs, which means that their key building blocks are organic (i.e., carbon-based) materials. Unlike LEDs, which are small-point light sources, OLEDs are made in sheets that are diffuse-area light sources.
Why is OLED called organic?
OLED, an advanced form of LED, stands for organic light-emitting diode. Unlike LED, which uses a backlight to provide light to pixels, OLED relies on an organic material made of hydrocarbon chains to emit light when in contact with electricity.
How long do EL panels last?
Generally speaking, EL has a lifespan of about 4,000-6,000 hours, however with our MEGA series of inverters, this lifespan is increased to about 6-8,000 hours, but we’ve seen products last well over 10,000 hours using these inverters.
Can EL Wire be used outdoors?
Although EL wire has great staying power, its color will eventually fade from sun exposure. Keeping your EL wire outdoors in direct sunlight will cut the life span to one to two years. When kept indoors or with limited outdoor exposure, your EL wire’s color will last as long as three years.
