Visual Display Resolution – a New Metric based Contrast Modulation and Structural Similarity

Determining the resolution of an image used to be easy.  In flat panel displays you counted the number of full-color pixels composed of RGB sub-pixels.  In projectors, the count of the imager elements determined resolution.   Well times have changed.  In flat panels, architectures are now common that use sub-pixel rendering algorithms to display color …

Understanding Trade-offs in Microdisplay and Direct-View VR Headset Designs

  Introduction There is currently some debate about which VR headset architecture will create the “best” images with the “best” form factor at the “right” price. In writing this white paper, we started the process by framing the issues as a choice between microdisplay-based designs vs. direct-view panel designs. But along the way, it became …

Visual Resolution of Display Screens

  Summary The ability of display screens to accurately present fine image details is specified by the visual resolution which can be measured and evaluated according to the IDMS (International Display Measurement Standard issued by the International Committee for Display Measurement, ICDM). In the second half of the year 2015 some display metrology laboratories started …

Wide Color Gamut Displays Bring Opportunity and Some Concerns

  The UHD-TV specification calls for a new color gamut, the so-called 2020 gamut.  It expands the RGB primaries to the edge of the spectral locus to create the biggest color gamut yet.  Displays that can achieve this gamut, or close to it, will show us colors we have never before seen on electronic displays, …

Options for Wired Infrastructure Multiply Creating New Opportunities

  It used to be that organizations would set up multiple wired infrastructure networks to handle phone, data, video, audio, control, security, KVM, etc. Now, multiple options are emerging that can allow one or two networks to do all the stuff of multiple networks in the past.  That is creating lots of new opportunities for …
