The shadow mask is installed to the screen using metal pieces [20] or a rail or frame [21] [22] [23] that is fused to the funnel or the screen glass respectively, [24] holding the shadow mask in tension to minimize warping (if the mask is flat, used in flat screen CRT computer monitors) and allowing for higher image brightness and contrast ...
The purpose of bias lighting is to reduce the perceived brightness of the display as a result of the contrast with the slightly illuminated area around it. [1] This reduces the eye strain and fatigue that occurs when viewing a bright display against a very dark background for an extended time, [1] and increases the perceived blackness, perceived highlights, and overall contrast of the display.
A catoptric cistula is a box with insides made of mirrors so as to distort images of objects put into the box. Checker shadow illusion: The checker shadow illusion shows that when a shadow is cast onto a checked board, the colours of squares A and B in the photos appear to be different, when in fact they are the same. Chubb illusion
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information. Liquid crystals do not emit light directly [1] but instead use a backlight or reflector to produce images in color or monochrome. [2]
A Pixel Qi screen installed in an OLPC XO laptop operating in transmissive mode. The screen is in color mode and is retro-illuminated. A transflective liquid-crystal display [1] is a liquid-crystal display (LCD) with an optical layer that reflects and transmits light (transflective is a portmanteau of transmissive and reflective). [2]
Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity. Graphics artists can choose from a variety of light sources ...
A monitor filter is an accessory to the computer display to filter out the light reflected from the smooth glass surface of a CRT or flat panel display. [1] Many also include a ground to dissipate static buildup.
Glasses containing liquid crystal that will let light through in synchronization with the images on the cinema, television or computer screen, using the concept of alternate-frame sequencing. This is the method used by nVidia, XpanD 3D, and earlier IMAX systems. A drawback of this method is the need for each person viewing to wear expensive ...
