As the Future Technologies Advances: So Does PMOLED


What is an OLED display? This is nothing else, but an organic light emitted diodes, look at this at this display as sandwich that has few ingredient in-between itself, in more technical term; these outer layer sandwiches are made up of carbon base films between two charged electrodes, 1: A metallic cathode and another, a transparent anode, usually being glass.  There are 4 layers in the organic film: 1) hole-injection 2) Hole-transport layer 3) An emissive 4) Electrons emission layer.  There are two types or OLEDs I would like to talk about which are Passive and Active OLEDs. Both of these technologies are unique in their own way; however to better understand the difference here is a break down.

Passive OLEDs has an organic layer and strips of cathode and node, while Active OLEDs has a full layer of cathode, organic layers and anode "TFT Matix".  Passive OLEDs are very easy to make while Active OLEDs has a higher technology yield to make.  Passive OLEDs are use for small sizes up to 6 inches while Active OLEDs uses for large screens.  Passive OLEDs applications are Audio, Automobiles, meters, and industrial while Active OLEDs use for mobile phone, video players and TV.  PMOLED has a better power consumption of 200mW than LCD who has 500mW and VFD as 680MW. The Passive matrix OLEDs has a better response time, lifetime (100k), view angle (H: 175 and V: 175) and contrast 2000:1.
