2.5.1.9 Linearity
Measure the linearity with a 17 horizontal line x 13 vertical line crosshatch.
Horizontal linearity : fH=30-40kHz whole : 15% or less, adjacent : 7% or less
fH=40-60kHz whole : 12% or less, adjacent : 7% or less
fH=60-115kHz whole : 10% or less, adjacent : 7% or less
Vertical linearity : whole : 10% or less, adjacent : 7% or less
Calculation expression : (Xmax - Xmin)
(Xmax + Xmin)/2
* If any doubts arise about the judgment, judge with the horizontal/vertical width tolerance
of ±3mm, picture position: |L1-L2|≤3.0mm and |L3-L4|≤3.0mm.
