ZScreen is a push-pull electro-optical liquid crystal modulator that is placed immediately in front of the projector lens or computer screen to alternately polarize the light from each video frame. It circularly polarizes the frames clockwise for the right eye and counterclockwise for the left eye.
Nixie tubes, LED display and VF display, top to bottom Display board at Frankfurt (Main) Hauptbahnhof (2005). A display device is an output device for presentation of information in visual [1] or tactile form (the latter used for example in tactile electronic displays for blind people). [2]
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 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.
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.
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 ...
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 ...
As a result, the greater the portion of our field of view that is occupied by a display, the greater is the need for high refresh rates. This is why computer monitor CRTs usually run at 70 to 90 Hz, while CRT TVs, which are viewed from further away, are seen as acceptable at 60 or 50 Hz (see analog television standards). [6]
