TAILIEUCHUNG - Lecture Computer graphics: Lecture 4 - Fasih ur Rehman

LCD basically consists of a layer of liquid crystal, sandwiched between two polarizing plates. The polarizers are aligned perpendicular to each other (one vertical and the other horizontal), so that the light incident on the first polarizer will be blocked by the second. This is because a polarizer plate only passes photons (quanta of light) with their electric fields aligned parallel to the polarizing direction of that plate. | Computer Graphics Lecture 04 Fasih ur Rehman Last Class Overview of Graphics Systems Display Devices Colors and colored displays Raster displays and frame buffer Today’s Agenda Overview of Graphic Systems Vector Displays Movie Standards LCD’s Some Definitions A rectangular array of points or dots is called Raster. A Pixel is picture element of raster. A row of pixels is known as Scan Line. Picture elements stored in memory are called Frame Buffer. Pixel Scan Line Resolution The Resolution is defined as the number of dot per inch or centimeter that can be plotted horizontally & vertically. Higher the resolution, smaller the spot size. Resolution is related with quality of the graphics system. Higher the resolution, better the graphics system High quality resolution is 1280x1024 The intensity distribution of spots on the screen has Gaussian distribution. Adjacent points will appear distinct as long as their separation is greater than the diameter at which each spot has intensity of .
