Different display technologies have vastly different temporal characteristics, leading to perceptual differences of motion, flicker, etc. Sketch of some common display technologies' temporal behaviour. The figure shows a sketch of how different technologies present a single white/grey frame. Time and intensity is not to scale.
Typically less than 0.01 ms, as low as 2 μs, [15] [19] but limited by phosphor decay time (around 5 ms) Estimates varying from under 0.01 ms to as low as 1 μs. [20] [21] Frame rate (refresh rate) 60–85 fps typically, some CRTs can go even higher (200 fps at reduced resolution [22]); internally, display refreshed at input frame rate speed
The following is a comparison of high-definition smartphone displays, containing information about their specific screen technology, resolution, size and pixel density. It is divided into three categories, containing smartphones with 720p , 1080p and 1440p displays.
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 ).
AMOLED (active-matrix organic light-emitting diode; / ˈ æ m oʊ ˌ l ɛ d /) is a type of OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels .
The following is a list of smartphones with a high refresh rate display.The refresh rate is the number of times in a second that a display hardware updates its buffer. It is not to be confused with the touch response rate, which is the frequency that the touchscreen senses input, or the frame rate, which describes how many images are stored or generated every second by the device driving the ...
In this time frame, with the notable exception of Apple, almost all desktop, laptop, and display manufacturers gradually moved to promoting only 16:9 aspect ratio displays. By 2011, the 16:10 aspect ratio had virtually disappeared from the Windows laptop display market (although Mac laptops are still mostly 16:10, including the 2880 × 1800 15 ...
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.
