In October 2008, Apple announced that it would be using LED backlights for all of its notebooks and new 24-inch Apple Cinema Display, and one year later it introduced a new LED iMac, meaning all of Apple's new computer screens became LED-backlit displays. Almost every laptop with a 16:9 display introduced since September 2009 uses LED-backlit ...
[11] [12] This is conceptually similar to a strobing backlight. Sharp Corporation use a "scanning backlight" [13] [14] which rapidly flashes the backlight in a sequence from the top to the bottom of the screen, during every frame. Nvidia has licensed a strobe backlight [15] technology called LightBoost to display manufacturers.
Burn-in on a monitor, when severe as in this "please wait" message, is visible even when the monitor is switched off. 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.
An LCD with LED-Backlight may be edge- or direct-lit: [9] edge-lit (ELED): LEDs form a line around the rim of the screen. May additionally support: frame dimming: adjusts the brightness of the entire backlight based on the content displayed, as if local dimming was supported but only with a single zone
The crystals may exist in one of two stable orientations ("black" and "white") and power is only required to change the image. ZBD Displays is a spin-off company from QinetiQ who manufactured both grayscale and color ZBD devices. Kent Displays has also developed a "no-power" display that uses polymer stabilized cholesteric liquid crystal (ChLCD ...
Intel DPST technology aims to adaptively reduce backlight brightness while maintaining satisfactory visual performance. The Intel DPST subsystem analyzes the image to be displayed and it uses a set of algorithms to change the chroma value of pixels while reducing the brightness of backlight simultaneously such that there is minimum perceived ...
Image persistence, or image retention, is a phenomenon in LCD and plasma displays where unwanted visual information is shown which corresponds to a previous state of the display. It is the flat-panel equivalent of screen burn-in. Unlike screen burn-in, the effects are usually temporary and often not visible without close inspection.
The transmittance of a pixel of an LCD panel typically does not change linearly with the applied voltage, [14] and the sRGB standard for computer monitors requires a specific nonlinear dependence of the amount of emitted light as a function of the RGB value.
