How LG OLED TV Works


LG OLED TV is said to be organic because it is made of carbon and hydrogen. OLED emits their own light and therefore does not require any other light source (backlight) to turn it on, another case with an LCD that requires backlight to make it work. This is the main reason for lower power consumption in OLED than the LCD. In the absence of a backlight unit, OLED displays can be slimmer than LCD displays. Here, LG TV shows OLED TV is so thin. The most important part in the manufacture of OLED is installing the organic layers on its substrate layer. This can be done in 3 ways.

First is in a vacuum. The organic molecules are heated with caution in order to evaporate and allowed to condense to form a thin film coating on top of the cooled substrate layer. Poses is considered expensive and less efficient. The second way of LG OLED TV is by using gas (carrier gas) to remove vapors of organic molecules to the substrate layer cooled, in which the organic molecules in fog form a thin film coating. This process is performed on the hot reactor chamber insulated with low pressure. The method of using the carrier gas is thought to increase efficiency and reduce costs of OLED. Method such as inkjet printing is the third. By using inkjet printers, OLED is sprayed onto the substrate as well as the ink is sprayed onto paper. Inkjet technology greatly reduces manufacturing costs and also allows OLED to a very large film to make such a large display screen of 80-inch TV screens or electronic billboards.

LG OLED TV emits light such LED components. Current electric flows from the cathode layer to the anode layer by organic molecules layer. The cathode layers provide electrons to the organic emissive layer. Then throw anode layer of electrons from the conductive organic layer. Then the electrons also fill the holes of the electron, pulling out energy in the form of a photon of light. And the OLED emits no light. Color of the emitted light depends on the type of organic molecules used in the emissive lining. Manufacturer uses several types of organic layers in OLED. Brightness of OLED is determined by the level of acceptable electrical current. More and more electric current is the more bright light of OLED.

LG OLED TV substrate and organic layers are thinner, lighter and flexible than layer on the display screen of LED or LCD. OLED is lighter or brighter than the LCD. OLED does not need a back light source while LED requires a backlight because it cannot produce its own light. OLED is more energy efficient than LED. It is because it does not require any other light source. OLED is more easily manufactured on a large size. OLED has a wide viewing angle because OLED emits its own light.
