BUNI= Bmax-Bmin X 100% Bmax Bmax: Maximum brightness Bmin: Minimum brightness Notes 7) Definition of Flicker level Flicker Voltage pp F x 100 % LMD Voltage dc ♦ One maximum value of three estimated values. ♦ For this test ,an LMD(Light Measurement Device)is needed with adequate response time to track any visible rate flicker component and with a voltage level output proportional To luminance intensity. ♦ Test Pattern: For dot inversion Driving(Gray levels of foreground dots on the test panel Are G22,G32,and G45) ♦ Test Point :Center point of the display area Note 8) Definition of Crosstalk (Refer to the VESA STD) The calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh, as follows: Lmax -Lmin - 13 -
