  Active Matrix VFD
As with conventional VFDs, the Active matrix VFDs have cathode (filaments) to emit electrons, mesh grids to diffuse electrons, and anodes coated with phosphor to which attract electrons and emit light.
The standard lead pin of an active Matrix VFD is 6.0mm in length and 2.0mm pitch.
Basically, the Active Matrix VFD is subjected to the same reliability test standards "TT-99-3050A" as the conventional VFD.

 Active Matrix
This method of driving an LC matrix is called Active Matrix (AM) addressing and AM LCD panels have become the most commonly used in notebook computers, desktop monitors and video projectors.
In the meantime, work continued on passive matrix displays, with new techniques, such as dual-scanning of STN displays (known as DSTN) providing sufficient improvements to the basic design to persuade researchers that it was worth persevering with the cheaper technology.
Active matrix OLEDs are usually made with polysilicon transistors although research and development work is being undertaken to make amorphous silicon active matrix OLEDs.

 Active matrix (Thin Film Transistor, TFT) - Glossary Entry - Mobile Phone Directory
TFT (Thin Film Transistor or Active Matrix) LCD is a mass produced display technology that offers improved refresh rates and good contrast over passive matrix displays.
It achieves this by adding an individual switch at every single pixel, which means that voltage can be actively supplied to individual pixels instead of one row and one column receiving current at a time.
The two disadvantages to TFT displays are that they have higher power consumption as each individual pixel drains current, and they are more expensive; it is not cheap to manufacture perfect large sheets of transistors, as current processes are low-yield.

 Chp 5: Basic Active Matrix Technology
The use of thin-film transistors (TFT) as the preferred nonlinear element is based on the pioneering work of Peter Brody (1973), the "father" of the TFT active matrix.
Although many active matrix technologies have been explored, the dominant ones today are hydrogenated amorphous silicon (a-Si) thin-film transistors, metal- insulator-metal (MIM) diodes, and low-temperature polysilicon (p-Si) thin-film transistors.
The active matrix is a method of addressing an array of simple LC cells--one cell per monochrome pixel.

 Active matrix display /  TFT
Also known as Thin Film Transistor (TFT), an active matrix display is a liquid crystal display found on notebook computers and flat panel displays.
With active matrix displays, each pixel is controlled by one to four transistors which commonly make the screens faster, brighter and more colorful than passive matrix.
Because of this improved technology, active matrix screens commonly tend to be a more expensive but better quality than a passive matrix display.

 Universal Display: Active-matrix OLED Displays
An active-matrix OLED (AMOLED) display consists of OLED pixels that have been deposited or integrated onto a thin film transistor (TFT) array to form a matrix of pixels that illuminate light upon electrical activation.
In contrast to a PMOLED display, where electricity is distributed row by row, the active-matrix TFT backplane acts as an array of switches that control the amount of current flowing through each OLED pixel.
Typically, this continuous current flow is controlled by at least two TFTs at each pixel, one to start and stop the charging of a storage capacitor and the second to provide a voltage source at the level needed to create a constant current to the pixel.
