This part of IEC 62629 determines the following measuring methods for characterizing the performance of stereoscopic display devices using either active or passive glasses. This standard focuses on the types of stereoscopic displays using glasses as follows: The types of stereoscopic displays reproducing temporally interlaced images and applicable glasses are: - displays representing temporally interlaced (high frame rate) images and active glasses (time dividing shutter glasses), and - displays with front screen switchable polarizer representing temporally interlaced images and linear or circular polarizer passive glasses. The types of stereoscopic displays reproducing spatially interlaced images and applicable glasses are: - displays with patterned retarder representing spatially interlaced images and linear or circular polarizer passive glasses. Some parts of these measuring methods may also be applied to other types of stereoscopic displays using glasses not listed above. The measuring items for the sets of stereoscopic display and glasses are as follows: a) luminance, b) luminance uniformity, c) interocular luminous difference, d) dark-room contrast ratio, e) interocular contrast difference, f) colour gamut, g) white chromaticity, h) white chromatic uniformity, i) interocular chromatic difference, j) interocular crosstalk, and k) interocular crosstalk screen position dependency (interocular crosstalk uniformity). The measuring parameters are as follows: l) viewing direction dependency, m) dependency on in-plane rotation of lens, n) dependency on tilt angle of lens, and o) viewing distance dependency. The measuring items for the glasses are as follows: p) transmittance (open state), q) extinction ratio, r) colour shift (open state, on-state), s) interocular transmittance, t) interocular contrast difference, u) interocular chromatic difference, v) response time (open state to/from closed state) of active glasses, and w) uniformity of lens. The measuring parameters are as follows: x) angular characteristic, and y) temperature dependency.
