Display size. On 2D displays, such as computer monitors and TVs, the display size or viewable image size ( VIS) is the physical size of the area where pictures and videos are displayed. The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches.
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. Liquid crystals do not emit light directly [ 1] but instead use a backlight or reflector to produce images in color or monochrome.
A common size for LCDs manufactured for small consumer electronics, basic mobile phones and feature phones, typically in a 1.7" to 1.9" diagonal size. This LCD is often used in portrait (128×160) orientation. The unusual 5:4 aspect ratio makes the display slightly different from QQVGA dimensions. 160×128 (20k) 160 128 20,480 5:4 UNNAMED UNNAMED
This table can be used in a number of ways : Find the optimal distance for a given screen. Example: for a 4K UHD screen 140 cm high (112 inches diagonal), the optimal distance is 140 × 1.6 = 224 cm. Find the right screen size. Example: for a 1080 HDTV used at a distance of 250 cm, you need to find a screen whose height is close to 250. /.
LCD television. A liquid-crystal-display television ( LCD TV) is a television set that uses a liquid-crystal display to produce images. It is by far the most widely produced and sold type of television display. LCD TVs are thin and light, but have some disadvantages compared to other display types such as high power consumption, poorer contrast ...

These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed ...
A television set or television receiver (more commonly called TV, TV set, television, telly, or tele) is an electronic device for the purpose of viewing and hearing television broadcasts, or as a computer monitor. It combines a tuner, display, and loudspeakers. Introduced in the late 1920s in mechanical form, television sets became a popular ...
Flat-panel displays can be divided into two display device categories: volatile and static. The former requires that pixels be periodically electronically refreshed to retain their state (e.g. liquid-crystal displays (LCD)), and can only show an image when it has power. On the other hand, static flat-panel displays rely on materials whose color ...
