Ignoring transmission time for a moment, the response time is the sum of the service time and wait time. The service time is the time it takes to do the work you requested. For a given request the service time varies little as the workload increases – to do X amount of work it always takes X amount of time.
Response time 0.01 ms [10] to less than 1 μs, [11] but limited by phosphor decay time (around 5 ms) [12] 1–8 ms typical (according to manufacturer data), older units could be as slow as 35 ms [13] Typically less than 0.01 ms, as low as 2 μs, [10] [14] but limited by phosphor decay time (around 5 ms)
Response time compensation for liquid-crystal displays is also known as "Overdrive". LCDs moderate light flow by rotating liquid crystal molecules to various alignments where they transmit more or less light depending on the electrical setting at each individual pixel .
Response time (technology), the time a generic system or functional unit takes to react to a given input Display response time, the amount of time a pixel in a display takes to change; Round-trip delay time, in telecommunications; Emergency response time, the amount of time that emergency responders take to arrive at the scene of an incident ...
Reducing the time an LCD pixel is lit can be accomplished via turning off the backlight for part of a refresh. [4] This reduces motion blur due to eye tracking by decreasing the time the backlight is on. In addition, strobed backlights can also be combined with motion interpolation to reduce eye-tracking-based motion blur.
The first HDD [11] had an average seek time of about 600 ms. [12] and by the middle 1970s, HDDs were available with seek times of about 25 ms. [13]Some early PC drives used a stepper motor to move the heads, and as a result had seek times as slow as 80–120 ms, but this was quickly improved by voice coil type actuation in the 1980s, reducing seek times to around 20 ms.
One component that makes up the response time is the time spent executing the software – hence if the software worst case execution time can be determined, then the designer of the system can use this with other techniques such as schedulability analysis to ensure that the system responds fast enough.
This lag time has been measured as high as 68 ms, [1] or the equivalent of 3-4 frames on a 60 Hz display. Display lag is not to be confused with pixel response time, which is the amount of time it takes for a pixel to change from one brightness value to another. Currently the majority of manufacturers quote the pixel response time, but neglect ...
