“…30,31 Indeed in a series of experiments, Spencer et al found that observers could discriminate displays when pixel sizes were smaller than 0.5 arcmin. 32 These experimental findings and anecdotal research with 4K technology indicates that there is great value maintaining full-resolution data via temporal multiplexing in stereo imaging. SEAV OLED technology offers the opportunity to achieve low-crosstalk s3D imagery that retains the native resolution.…”

240 Hz OLED technology properties that can enable improved image quality

Large screen Organic Light Emitting Diode (OLED) technology is finally emerging as a technology ready for consumer use. OLED has a number of areas in which it can in principle be better than Liquid Crystal Displays (LCDs); two ways in particular are that OLED technology can achieve black levels that are much darker than LCDs, and the OLED pixels can switch extremely rapidly. These differences can permit OLED displays to outperform LCD under a number of conventional scenarios, but it can also enable some dramatically improved stereoscopic 3D (s3D) displays, including full‐resolution temporal multiplexing with more than two views. In this paper, we review a set of experiments evaluating the strengths and weaknesses of OLED technology in general with a particular emphasis on understanding how the strengths of OLED technology can be leveraged to maximize the performance of an s3D display system.

“…The limit of human visual perception for an observer with a visus of one is by definition located at f vis,0 = 30 [cycles/°]. For the special case of a green grating on a black background this cutoff frequency may even be as high as 60 [cycles/°] for foveal vision as reported by Spencer et al [5]. Figure 1 illustrates a typical bandpass characteristic of human contrast sensitivity, i.e.…”

We introduce a new method for evaluation of sparkle of the combination of display and AG-layer by application of a weighting of the Fourier amplitudes of the random luminance modulations that are perceived as sparkle, according to the contrast sensitivity function of the human visual system. This new approach provides improved sensitivity to small sparkle variations, better control of parasitic low frequency components caused by non-uniformities of display illumination and an improved match to visual ratings with subtle differences in the low sparkle region.

Over the past few decades the term "eye-limited resolution" has seen significant use. However, several variations in the definition of the term have been employed and estimates of the display pixel pitch required to achieve it differ significantly. This paper summarizes the results of published evaluations and experiments conducted in our laboratories relating to resolution requirements. The results of several evaluations employing displays with sufficient antialiasing indicate a pixel pitch of 0.5 to 0.93 arcmin will produce 90% of peak performance for observers with 20/20 or better acuity for a variety of visual tasks. If insufficient antialiasing is employed, spurious results can indicate that a finer pixel pitch is required due to the presence of sampling artifacts. The paper reconciles these findings with hyperacuity task performance which a number of authors have suggested may require a much finer pixel pitch. The empirical data provided in this paper show that hyperacuity task performance does not appear to be a driver of eye-limited resolution. Asymptotic visual performance is recommended as the basis of eye-limited resolution because it provides the most stable estimates and is well aligned with the needs of the display design and acquisition communities.
