Yes, AMOLED is a part of OLED only. Just that AMOLED are used only in mobile phones and cameras, whereas OLEDs are used by the TV manufacturers in making their OLED TV. I have even heard that LGs have unveiled their OLED TV in the recent CES and is planning to roll it out in the mid of this year.
OLED displays can use either passive-matrix (PMOLED) or active-matrix addressing schemes. Active-matrix OLEDs (AMOLED) require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes, that's why AMOLED is considered more reliable and useful as well as it is less expensive too.
LG's OLED TV uses four base colors White, Red, Green, and Blue through a color filter. Other types of OLED uses only 3 base colors that are tuned to provide a full range of colors without the need for a fourth sub-pixel.
The actual price hasn't been disclosed by any of the brands who unveiled their OLED TVs.
An organic light emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compounds which emits light in response to an electric current. This layer of organic semiconductor material is situated between two electrodes. Generally, at least one of these electrodes is transparent.
The basic OLED TV design (called a "True-OLED" TV) uses 3 color OLED sub-pixels (Red, Green and Blue) to create each 'pixel'. But some companies are using a different archicture, called WOLED-CF which uses four white OLED subpixels with color filters on top (RBG and W). This is also called a RGBW design. The WOLED-CF technology was developed by Kodak (and the IP is now owned by LG Display), and it should make the OLED panel easier to make. However it will also be less efficient. LG Display's OLED TVs which will be released in 2012 will be based on this design.
To understand Super AMOLED you first need to understand its origins. It started with OLED, which stands for 'organic light-emitting diode' and consists of a thin organic film with electrodes at either side. As soon as an electric current is applied to the film it emits light. AMOLED is an 'active-matrix organic light-emitting diode'. It adds a layer of semiconducting film behind the OLED panel which allows it to more quickly activate each pixel. That increased speed makes it ideal for larger, higher definition displays with a lot of pixels. In fact, it's as much as 1000 times faster than LCD. AMOLED screens also tend to have great contrast, as the light on the screen comes from each individual pixel rather than a backlight; when it needs to create a black color it simply dims or turns off the relevant pixels, for a true, deep black. AMOLED screens also use a large color gamut, so they can display a wide range of colors, but that can also cause images to look very vibrant or over-saturated.

There are a lot of similarities to be had between the LED TV and the OLED TV. Both the LED TV and the OLED television feature some of the best contrast levels in the TV market. They both have deeper blacks than other televisions. This means that the black comes across as darker, and contrasts more with the other colors. This helps these other colors to stand out more. Both types of TVs are also thin, and are generally thinner than other types of TVs, including LCD TVs. There are a few major differences between the two types of televisions. The main differences focuses around the backlight. The LED TV is actually an LED backlit LCD TV, utilizing LEDs for the perfect backlighting. OLED TVs, on the other hand, do not need a backlight to operate. The LED technology is relatively old when compared to OLED technology. OLED TVs are newer, and are using the most recent form of LED technology. With LED technology, the lights are bright white and are forced through a color filter. With OLED TVs, each LED is actually creating the color that is needed. This is what creates the more dynamic picture, giving OLED TVs a nicer picture than LED TVs.
OLED panels are more energy-efficient than LCD and Plasma panels because they do not require a backlight to produce light. LCD panels use a backlight to illuminate the pixels, while Plasma panels use charged gas to create light. OLED panels have simpler construction compared to LCD and Plasma panels because they consist of organic compounds that emit light when an electric current is applied, eliminating the need for additional layers found in LCD and Plasma panels.
OLED: Organic Light Emitting Diode.
OLED's are brighter than LEDs, OLED's do not require Backlighting. They are easier to produce and can be made to larger sizes. They are expensive, water easily damages them.
