Up to 120 in (3.0 m) [42] Up to 150 in (3.8 m) [43] (152 in experimental) [44] Up to 97 in (2.5 m) [45] Maintenance Hazardous to repair or service due to high-voltage, requires skilled convergence calibration and adjustments for geographic location changes. [46] Glass display tube is evacuated and carries risk of implosion if improperly handled.
Nevertheless, the plasma displays' relatively large screen size and 1 inch (25.4 mm) thickness made them suitable for high-profile placement in lobbies and stock exchanges. Burroughs Corporation, a maker of adding machines and computers, developed the Panaplex display in the early 1970s.
1985; low-contrast LCD screen with green background (instead of orange/yellow plasma screen with black background on a Compass laptops). [4] This model was based on a MSDOS 2.11 and a bunch of apps burned on ROM that fit in the ROM tray in front. GRiDCASE 3 with red plasma screen
4:3 and 16:9 were used on the WEGA line of televisions. Many 4:3 monitors were produced as well as several models using an aspect ratio of 16:10 (such as the GDM-W900 and GDM-FW900). Competitors included Mitsubishi with their Diamondtron NF brand of flat aperture grille CRT displays, as used in certain computer monitors from Mitsubishi, NEC ...
Plasma displays modulate the "on" time of each sub-pixel, similar to DLP. Movie theaters use a mechanical shutter to illuminate the same frame 2 or 3 times, increasing the flicker frequency to make it less perceptible to the human eye.

An LCD screen used as a notification panel for travellers. Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of indium tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the axes of transmission of which are (in most of the cases) perpendicular to each other.
The diagonal screen size of a CRT television is limited to about 100 cm (40 in) because of size requirements of the cathode-ray tube, which fires three beams of electrons onto the screen to create a viewable image. A large-screen TV requires a longer tube, making a large-screen CRT TV of about 130 to 200 cm (50 to 80 in) unrealistic.
