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.
Before the advent of LCD screens, most computer screens were based on cathode-ray tubes (CRTs). When the same image is displayed on a CRT screen for long periods, the properties of the exposed areas of the phosphor coating on the inside of the screen gradually and permanently change, eventually leading to a darkened shadow or "ghost" image on the screen, called a screen burn-in.
3D animation of ambient occlusion enabled on the animation to the right. In the absence of hardware-assisted ray traced ambient occlusion, real-time applications such as computer games can use screen space ambient occlusion (SSAO) techniques such as horizon-based ambient occlusion including HBAO and ground-truth ambient occlusion (GTAO) as a faster approximation of true ambient occlusion ...
The white screen of death that appears on Dell computers. A White Screen of Death appears on several other operating systems, content management systems, [6] and on some BIOS, such as from Dell. It can be seen on iOS 7, and also when a white iPhone 5 or later or a white 5th generation iPod Touch screen freezes. Everything on the screen but the ...

Many computer systems have a memory hierarchy consisting of processor registers, on-die SRAM caches, external caches, DRAM, paging systems and virtual memory or swap space on a hard drive. This entire pool of memory may be referred to as "RAM" by many developers, even though the various subsystems can have very different access times ...
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 ...
Shadow mapping or shadowing projection is a process by which shadows are added to 3D computer graphics. This concept was introduced by Lance Williams in 1978, in a paper entitled "Casting curved shadows on curved surfaces."
