“…Therefore, the modulation transfer function (MTF) method was chosen to be another quantitative indicator for image blur judgment. MTF is used mainly to evaluate the contrast of an imaging system, and the contrast can be used to evaluate the sharpness of the pattern edge [41].…”

Transparent display is one of the main technologies in next-generation displays, especially for augmented reality applications. An aperture structure is attached on each display pixel to partition them into transparent and black regions. However, diffraction blurs caused by the aperture structure typically degrade the transparent image when the light from a background object passes through finite aperture window. In this paper, the diffraction effect of an active-matrix organic light-emitting diode display (AMOLED) is studied. Several aperture structures have been proposed and implemented. Based on theoretical analysis and simulation, the appropriate aperture structure will effectively reduce the blur. The analysis data are also consistent with the experimental results. Compared with the various transparent aperture structure on AMOLED, diffraction width (zero energy position of diffraction pattern) of the optimize aperture structure can be reduced 63% and 31% in the x and y directions in CASE 3. Associated with a lenticular lens on the aperture structure, the improvement could reach to 77% and 54% of diffraction width in the x and y directions. Modulation transfer function and practical images are provided to evaluate the improvement of image blurs.

“…3 can be Fourier transformed to yield a modulation transfer function (MTF) for the display with and without AG layer, similar to the evaluation of line-spreading induced by sub-pixel-layout and related rendering techniques as described in e.g. [2]. We have been evaluating the pixel crosstalk of a set of eight AG samples (specified by the manufacturer by gloss and haze levels) with two different instrumental arrangements.…”

“…This approach is described in detail in another contribution to this conference [1]. 2 The second approach is based on evaluation of the spreading of the intensity profile of a single column of subpixels or of suitable narrow linear light source (i.e. the line-spread function, LSF) by the scattering of the AG-layer.…”

We introduce the scattering-induced spreading of a narrow linear light source in transmission as an alternative method for characterization of image blurring induced by anti-glare layers. This novel method is compared to the recently presented concept of pixel crosstalk and to the transmissive scatter distribution function of anti-glare layers measured in two different ways. The reduction of transmittance modulation is presented as an additional method for characterization of image blur. The ranking of the results is compared to a generalized haze level of the AG samples as obtained from the transmittance distribution functions measured with two different methods.

When we saw the object behind the transparent display, the image blur was observed. In this paper, the phenomenon was evaluated by measuring the diffraction width and MTF (modulation transfer function). By optimizing the pixel layout, the diffraction width of object image could be decreased to 54% in X direction and 48% in Y direction, the MTF also showed that the image quality could be improved by modifying the structure of transparent display.
