A vector monitor, vector display, or display device used for computer graphics up through the 1970s. It is a type of CRT, similar to that of an early oscilloscope. In a vector display, the image is composed of drawn lines rather than a grid of glowing pixels as in raster graphics. The electron beam follows an arbitrary path tracing the connected sloped lines, rather than following the same horizontal raster path for all images. The beam skips over dark areas of the image without visiting their points.

Some refresh vector displays use a normal phosphor that fades rapidly and needs constant refreshing 30-40 times per second to show a stable image. These displays, such as the Imlac PDS-1, require some local refresh memory to hold the vector endpoint data. Other Tektronix 4010, use a special phosphor that continues glowing for many minutes. Storage displays do not require any local memory. In the 1970s, both types of vector displays were much more affordable than bitmap raster graphics displays when megapixel computer memory was still very expensive. Today, raster displays have replaced nearly all uses of vector displays.

Vector displays do not suffer from the display artifacts of aliasing and pixelation—especially black and white displays; color displays keep some artifacts due to their discrete nature—but they are limited to displaying only a shape"s outline (although advanced vector systems can provide a limited amount of shading). Text is crudely drawn from short strokes. Refresh vector displays are limited in how many lines or how much text can be shown without refresh flicker. Irregular beam motion is slower than steady beam motion of raster displays. Beam deflections are typically driven by magnetic coils, and those coils resist rapid changes to their current.

In 1963, Ivan Sutherland at MIT first used a vector graphic display for Sketchpad, his pioneering CAD program. In 1968, he and his team again used a vector monitor to display wireframe images of 3D models. This time the display was head mounted. The obviously heavy system was held up by a support arm structure called The Sword of Damocles. The system is widely considered to be the first computer-based virtual reality.

In 1970, at the UK Farnborough Airshow, Sperry Gyroscope (Bracknell, England) exhibited the first ever vector graphic video display from a UK company. It featured an analogue monochrome display with special electronics, designed by Sperry"s John Atkins, that allowed it to draw vectors on screen between two pairs of coordinates. At Farnborough the display was used to demonstrate the capabilities of the new Sperry 1412 military computer - it was shown running software that drew, in real time, a wire-frame rotating cube that could be speed-controlled in any of its three dimensions. That demonstration created significant interest in the Sperry 1412 computer, which then went on to be at the heart of a number of major projects for the French Navy and the Royal Navy during the period 1972 to 1992.

Notable among vector displays are Tektronix large-screen computer terminals that use direct-view storage CRTs. (The CRT has at least one flood gun, and a special type of display screen, more complicated in principle than a simple phosphor.) But that permanent image cannot be easily changed. Like an Etch-a-Sketch, any deletion or movement requires erasing the entire screen with a bright green flash, and then slowly redrawing the entire image. Animation with this type of monitor is not practical.

Vector displays were used for head-up displays in fighter aircraft because of the brighter displays that can be achieved by moving the electron beam more slowly across the phosphors. Brightness was critical because the display needed to be clearly visible to the pilot in direct sunlight.

Hewlett-Packard made a series of large-screen X-Y (vector) displays, the first of which was the 20 MHz 8x10-inch model 1300. The CRT had an internal, specially contoured, very fine mesh operating at low potential, which was placed after the deflection plates at the gun exit. The 17KV electrostatic field between this mesh and the separate, conductive coating charged to final accelerating potential inside the CRT funnel, accelerated the electron beam axially as well as radially, expanding the possible image size to cover the 8x10" screen of the 17.75-inch long CRT. Without the mesh, the 8x10-inch CRT would have had to be almost three times as long.

Some vector monitors are capable of displaying multiple colors, using either a typical shadow mask RGB CRT or two phosphor layers (so-called "penetration color").

Taiwan"s AU Optronics (AUO) opened its second European base for production of LCD displays in Slovakia, in a move which could help a recovery in the heavily export-reliant economy. The plant located in the western town of Trencin should play a key role in the manufacture, assembly and sale of la

I"m currently in the process of building a graphics engine for the SSD1289 display, which at the moment it appears to be quite a popular screen on the forum chat. My main inspiration for leaving the standard libraries and trying to create my own is partly a desire to make an animated game, and also I"ve noticed a lot of people are very quick to judge the Arduino because its a "learning tool" and not "powerful enough" for their students/needs.

The system I have created has been optimised from the ground up. It saves somewhere in the order of millions of instructions per second compared to an equivalent implementation using the UTFT library. Don"t get me wrong, the UTFT is an excellent library, its just not suitable for my needs. For example, a fill screen operation with UTFT is ~560ms, my implementation is ~19.7ms, gradient fills are only a little more expensive.

For now here is a video of my test app running. I have some screen shots also, but the read code timing is slightly incorrect so there are a few misaligned pixels. It is an audio analyser running a 128 point FFT. I have yet to put in many features like text rendering and orientation rotation, but the core is running great.
