Antialiasing, as the name suggests, is a technique used to combat an effect known as aliasing. When a line is drawn on a piece of paper, its edges appear smooth regardless of the line’s orientation. When a line is drawn on a computer display, whether CRT- or LCD-based, the limited resolution of the display means … Read more
The control grid regulates the number of electrons which are allowed to leave the gun of a CRT by using a negative voltage to repel the electrons. Once free of the control grid’s influence, the electrons then need to be accelerated down the tube to ensure that they strike the phosphor face-plate lining with sufficient … Read more
Anisotropic means “non-uniform shape” and it is because this filtering technique works on non-uniform, or uneven, shaped areas that it is more powerful, and takes much more processing power, than Point Sampling, bi-linear or tri-linear filtering. One of the problems with these methods is that they rely on a square as their sampling area and … Read more
Alpha-blending is a technique which can be used when computer graphics are laid on top of each other and one or more of the objects contain a transparent, or semi-transparent, portion. It ensures that the pixels of the graphic which are underneath a transparent area are visible through it and that their colour or brightness … Read more

There has been a lot going on around us. In the UK, we had an election that resulted in a ‘hung parliament’, with no single party having a clear majority. After a few days of negotiating and power-broking, we now have a formal coalition government for the first time in 65 years. In the past, … Read more
Developed by Fujitsu as an improvement to the Three Electrode Surface Discharge method of driving a PDP, which it invented in 1984, ALiS (Alternate Lighting of Surfaces) displays are not made up of enclosed pixel elements with the display electrodes fixed to both top and bottom substrates, as are conventional side discharge PDPs. Instead, the … Read more
In Super Twisted Nematic LCs, we see how multiplexed addressing allows an array of pixels to be controlled in such a way as to allow a high definition display to be built with liquid crystals. The method used to switch individual pixels in multiplexed displays, called passive matrix addressing, has many drawbacks, such as: Current … Read more
The following articles appeared in Display Monitor’s “Word of the Week” section. They define certain words or terms used in computer graphics and display technology. Some of the definitions may be a little dated now, but we leave them as we have been told that they are still useful. (Brief additions as updates were … Read more

In the end, in Display Monitor this week, we went with the media flow and decided to report the Apple iPad story, although we remain unconvinced that its importance is as huge as Apple and its many fans have made it (oops! ed.) It’s basically a bigger iPod Touch, as far as we can see … Read more
