Densitron OLED Technology OLED Technology Overview What is OLED? Organic Light-Emitting Diode (OLED) Display Panel, or Organic Electroluminescence (OEL), utilizes new generation technologies and is capable of delivering visual performance which is superior to that of other flat displays – brighter and clearer full-color images with more agile responding speed. How does OLED emit light? The basic structure of OLED is a sandwich formed with a thin and transparent semi-conducting anode of Indium Tin Oxide (ITO) and a metal cathode on both sides of an organic substrate. The organic material comprises...

Applications of OLED technology Today OLED displays are used in a wide range of devices that require electronic display panels. Some of the most popular types of applications are: • Personal Digital Assistants (PDAs) • Audio/Visual display systems • Mobile telephones • Portable games • Personal care appliances • Household goods • Dynamic information displays • Medical handheld devices However, the number of possible applications is growing every day, and is not restricted to particular industry sectors or product types.

Densitron OLED Technology PMOLED vs AMOLED A PMOLED display uses a simple control scheme in which you control each row (or line) in the display sequentially (one at a time). PMOLED electronics do not contain a storage capacitor and so the pixels in each line are actually off most of the time. To compensate for this you need to use more voltage to make them brighter. If you have 10 lines, for example, you have to make the one line that is on 10 times as bright. So while PMOLEDs are easy (and cheap) to fabricate, they are not efficient and the OLED materials suffer from lower lifetime (due to the...

and have no restriction on size or resolution. AMOLED Technology is currently for the most part manufactured for use within the consumer/multimedia Industry, focusing on products such as Mobile Phone Technology and PDA's. The first OLED products in the market used PMOLEDs - these were MP3 players, sub-displays on cellphones and radio decks for automobiles. The displays were small and usually with just one or two colors. When AMOLED panels started to emerge in 2007 and 2008 we have seen these larger displays in mobile video players, digital cameras, mobile phones main displays and even OLED TV...

PMOLED Lifetime Considerations PMOLED Technology has an inherent lifetime, associated with the physical degradation of the organic material used to generate the specific color(s). The half-life is classified as a the time taken for a unit to reach half brightness, operating under the conditions of: • Full brightness. • Room Temperature. The Half-life of the different colors is extrapolated from data taken over a 4000 hour period. Equally high temperature testing can determine the detrimental effect of continuous high temp operation on the Organic Reliability Test: Operation Luminance Degradation...

Life Time Estimation of Each Color Acceleration Factor Luminance Decay The OLED pixels physically shrink over time. Note that reducing the average operating brightness, and thus current consumption will have a positive effect on the half-life, extending the lifetime of the OLED.

PMOLED Charge Pump Characteristics. Voltage vs Brightness. Certain OLED Modules are designed with an integrated charge pump circuit, usually smaller sized modules which are inevitably designed into applications where space is constrained. In such cases it is useful to have an integrated charge pump circuit, with the feature of supplying one input Voltage. Note that the tolerance applied to the Voltage range affects the brightness of the OLED substrate as outlined in the example below.
