Twisted nematic LCs

Twisted Nematic (TN) LCs

by Dummy Admin

For nearly a hundred years after Friedrich Reinitzer observed cholesteryl benzoate changing into its liquid crystal state in 1888, nine years before the invention of the CRT, liquid crystals remained little more than a …

Shadow Mask

by Dummy Admin

Before the stream of electrons produced by the CRT’s cathode reach the phosphor coated faceplate, it encounters the shadow mask, a sheet of metal etched with a pattern of holes. The mask is positioned …

flat shading

Shading

by Dummy Admin

Objects in 3D scenes are most commonly created by fitting together a large number of polygons (usually triangles), edge to edge, creating a “wire-frame” which approximates the object’s surface. By drawing only those triangles …

SED

SED

by Dummy Admin

FEDs have proved difficult to develop and many companies had dropped their development projects in favour of other technologies. One company, however, has been working on a variation of the FED which currently looks …

saddle-saddle yoke

Saddle-Saddle Yoke

by Dummy Admin

The most common form of deflection yoke used in early colour monitors is known as a saddle-toroidal yoke. Its name comes from the shapes of the vertical and horizontal deflection electro-magnets’ windings. The winding …

Ray Tracing

by Dummy Admin

Effective as they can be at producing recognisable 3D scenes, Gouraud and Phong shading will never produce anything that could be described as photo-realistic. To achieve this, it’s necessary to use rendering techniques that …

Radiosity

by Dummy Admin

Ray tracing mimics the reflection and refraction of light rays in a 3D scene to produce image detail surpassing anything possible using Phong shading. Effective as it is, though, ray tracing by itself will …

Polysilicon

by Dummy Admin

Most silicon chips are made of single crystal silicon, which has a very low resistance to electron flow. However, silicon can exist in different forms (just as carbon can exist in the form of …

plasma display

Plasma Display

by Dummy Admin

In the search for a large sized flat screen display technology, LCDs do not have the field all to themselves. Though late to join the commercial battle, the next flat large screen devices being …

PALC

PALC

by Dummy Admin

A hybrid of the LCD and a PDP: the Plasma Addressed Liquid Crystal (PALC) display. The main drawback to the use of the TFT is that, as with any semiconductor process, manufacturing of large …

OLED

OLED

by Dummy Admin

In light emitting diodes (LEDs) based on inorganic light emitting materials, some of the photons released by the inorganic materials are also reabsorbed by them. In organic light emitting diodes (OLEDs), which produce light …

multi-domain vertical alignment

Multi-Domain Vertical Alignment (MVA)

by Dummy Admin

While Hitachi was developing its In-Plane Switching (IPS) Super TFT, Fujitsu and the chemical giant Merck were taking a different approach to increasing viewing angles and, in 1996, announced the development of a new …
