A backlight is a form of illumination used in liquid-crystal displays (LCDs) that provides illumination from the back or side of a display panel. LCDs do not produce light by themselves, so they need illumination (ambient light or a special light source) to produce a visible image. Backlights are often used in smartphones, computer monitors ...
IPS panel. IPS (in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces. The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions (in-plane). The molecules are reoriented by an applied electric field, while ...
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.
LED-backlit LCD. An Apple iPod Touch disassembled to show the array of white-edge LEDs powered on with the device. An LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting. [1] LED-backlit displays use the same TFT LCD (thin-film-transistor liquid-crystal ...
Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set. It is caused by cumulative non-uniform use of the screen. Newer liquid-crystal displays (LCDs) may suffer from a phenomenon called ...
Reports indicate that the display of the 12.9 inch second-generation iPad Pro has a high propensity of experiencing a "backlight bleed" failure, manifested as brighter halos of light bleeding through one edge of the screen.
Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...
For the majority of images it will consume 60–80% of the power of an LCD. OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight, [40] while OLED can use more than three times as much power to display a mostly white image compared to an LCD.
