ABSTRACT
Organic light emitting diode (OLED) display technology has been grabbing headlines in recent years. Now one form of OLED displays, LIGHT EMITTING POLYMER (LEP) technology is rapidly emerging as a serious candidate for next generation flat panel displays. LEP technology promises thin, light weight emissive displays with low drive voltage, low power consumption, high contrast, wide viewing angle, and fast switching times.
One of the main attractions of thi ....etc

PN-Junction Diode Characteristics

Forward Bias --- External battery makes the Anode more positive than the Cathode --- Current flows in the direction of the arrow in the symbol.
Reverse Bias --- External battery makes the Cathode more positive than the Anode --- A tiny current flows opposite to the arrow in the symbol.

Series-Connected Diodes

Use 2 diodes in series to withstand higher reverse breakdown voltage.
Both diodes conduct the same reverse saturation current, Is.

INTRODUCTION TO INDUSTRY

The term information technology came about in the 1970s. Its basic concept, however, can be traced back even further. Throughout the 20th century, an alliance between the military and various industries has existed in the development of electronics, computers, and information theory. The military has historically driven such research by providing motivation and funding for i ....etc

IMPATT Diode

Introduction
When the pn junction diode is reverse-biased, then current does not flow.
However when the reverse voltage exceeds a certain value, the junction breaks down and current flows with only slight increase of voltage. This breakdown is caused by avalanche multiplication of electrons and holes in the space charge region of the junction.
The pn junct ....etc

ZENER DIODE TESTER

ABSTRACT


The testing of zener diodes requires a variable dc power supply. A typical test circuit can be constructed, as shown in figure 4-19. In this circuit, the variable power supply is used to adjust the input voltage to a suitable value for the zener diode being tested. With the zener diode connected no current will flow until the voltage across the diode is equal to the zener ....etc

Flexible Organic LEDâ„¢s


Presented By: Ryan Evans



What the Flexible Organic Light Emitting Diode Consist of :

The Top Layer is the Cathode layer made of tungsten releases electrons when current is run through it.

Emissive Layer removes electrons from the cathode layer to make light.

Conductive layer is made from a type of organic plastic that removes the electron wholes

Then the Anode Layer that consist of removing and adding electron holes while the current is running through i ....etc

ABSTRACT

A new operational mode for diode-clamped multilevel inverters termed quasi two-level operation is proposed. Such operation aims to avoid the imbalance problem of the dc-link capacitors for multilevel inverters with more than three levels and reduces the dc-link capacitance without introducing any significant voltage ripple at the dc-link nodes. The proposed operation can be generalized for any number of levels. The validity of the proposed multilevel inverter operational mo ....etc
