Windows device driver information for AlphaScan 871S

The AlphaScan 871S LCD monitor display employs the liquid crystal display technology for producing images on the screen. The LCD technology functions by blocking out light. A liquid crystal display consists of 2 polarized glass pieces also known as substrates that have a liquid crystal substance between them. A backlight is responsible for producing light that will pass through the 1st substrate. Concurrently, electrical currents will cause the molecules of the liquid crystal to align and enable different light levels to pass through the 2nd substrate, and produce the images and colors displayed on the screen. Most LCD monitor display devices make use of the active matrix technology. In this technology, the TFT or thin film transistor is capable of arranging in a precise matrix tiny capacitors and transistors which will be sent to the display’s glass. To deal with a specific pixel, the accurate row must be switched on and a charge must be sent to the proper column.

The other kind of liquid crystal display technology is known as the passive matrix. This kind of display makes use of conductive metal on a grid for charging every pixel. However, although the materials used for the passive matrix technology are more affordable, this technology is rarely utilized since it has inaccurate voltage control and a slower response time than the active matrix technology. The AlphaScan 871S LCD monitor only displays information accurately at the display resolution it is developed for. This is called the native resolution. This monitor display deals with every individual pixel by utilizing a set matrix of vertical and horizontal dots. In the event that users alter the settings of the resolution, the LCD will automatically scale images and consequently, the display quality suffers. It is highly recommended you run a free registry scan for and AlphaScan 871S errors before installing any driver updates.
