Pixel Crosstalk:
A New Metric to Characterize DOI Loss Due to AG Treatments of Display Glasses
|
A method is proposed that characterizes the loss of image clarity caused by anti-glare coatings. The method uses high-resolution imaging, giving a distribution of scattered light that can be related easily to the clarity impression of the human eye. Results of different display lenses will be provided, and a new parameter is proposed to characterize the loss of image clarity. This can be applied to the specification and characterization of display lenses as well as the characterization of the final product.

Point-spread and line-spread function analysis as approaches to high-resolution scatter analysis of micro-structured anti-glare layers in transmission and reflection is introduced. This method was compared with that for conventional directional scanning (goniometric, conoscopic) by modeling two different basic types of reflection scattering, and the effect of the non-scattering side of anti-glare-treated sheet materials will be illustrated.

Revisiting Lighting Standards for Critical Viewing Tasks
|
With the adoption of electronic displays for critical viewing tasks, lighting environments were specified to minimize the reflection of ambient light from the display, maximizing display contrast and user performance. While these standards were necessary for early CRT displays, they have remained relatively unchanged in many environments despite adoption of replacement display technologies. Increased awareness of the intrinsically photosensitive retinal ganglion cell (ipRGC) pathways and their impact on operator circadian rhythms, alertness, and other non-image-forming-vision (NIF) processes, raises serious question about whether these lighting standards optimize user performance as originally intended or require serious revision.
