What is an active matrix?
Active matrix is a technology used in a liquid crystal of flat panels of laptops and laptops. This technology provides a more sensitive image to a wider range of viewing angles than passive matrix displays. Notebooks and notebook manufacturers prefer active matrix displays, also referred to as an active matrix liquid crystal display (AMLCD) or a thin film transistor (TFT) because they have a high quality image, a wide range of colors, fast response time and have a very low weight. They also consume less energy, a feature desired in portable devices.
There are two basic types of displays: active matrix and passive matrix. Passive matrix is older, simpler technology and has a much slower response time than active matrix screens. As the signal is processed in a passive matrix, there is also inaccurate voltage control. This creates a fuzzy image with a significant lack of contrast.
in active matrix to create aboutBrazovka use TFT. TFTs are basically small capacitors and switching transistors that are more dynamic than integrated circuits used in a passive matrix. This technology allows more accurate checks over the voltage used to charge the screen. This, in turn, allows pixels, small dots on the display that are charged to create an image to allow less light to make the image created more contrast. Along with faster response time, active matrix screens have a more definitive image and a more dynamic image, as the image can restore faster than passive matrix.
In the practical sense, you can see the difference in passive and active matrices when using the mouse indicator. When moving the pointer via the screen on the display of the passive matrix type, the "trailers" or double images that move through the screen behind the indicator will have a picture of "trailers" or double images. The indicator will also have a Fuzzier image with little contrast. In active matrix, movement of the mouse pointer does not create "trailers" and the image is Ostive.
The term “active matrix” was reportedly used for the first time by Dr. Peter Brody in 1975. This term used this term to describe the method of switching the individual elements of the flat panel using TFT cadmia selenium (CDSE) for each pixel. Although TFT is still used as a primary building block for active screens of matrix, diodes can also be used.
