39、ns Measurements shall be carried out under the standard environmental conditions, i.e. at a temperature of 25 C 3 C, a relative humidity of 25 % to 85 %, and a pressure of 86 kPa to 106 kPa. When different environmental conditions are used, these shall be noted on the report. 5.2 Set-up conditions 5

Each condition shall be noted on the relevant specification whenever any different conditions other than the standard set-up conditions are applied.

41、easurements shall be carried out at the standard measuring layout shown in Figure 1. When a different measuring layout is used, this shall be noted on the report. 5.2.2.2 Position of light measuring device The light measuring device shall be aligned perpendicular to the area to be measured on the sc

42、reen of the PDP module. 5.2.2.3 Standard measuring distance The standard measuring distance xois 2,5 V, where V is the screen height or the short side length of the screen. The measuring distance shall be between 1,6 V and 2,8 V. The measuring distance shall be noted on the report. 5.2.2.4 Aperture

43、angle of light measuring device The light measuring device shall be set at a proper aperture angle less than or equal to 2 degrees, and shall measure an area of at least 500 pixels which has an extent less than 10 % of the screen height. This area corresponds to including a circular measurement area

44、 of at least 26 lines in diameter in the case of a display panel having a square pixel consisting of 3 subpixels. The measuring distance and the aperture angle may be adjusted to achieve a viewing area greater than 500 pixels, which has an extent less than 10 % of the screen height if setting the ab

45、ove aperture angle is difficult. Such deviations from standard conditions shall be noted on the report. Key X0standard measuring distance = 2,5 V, where V is the screen height or short side length of screen. Figure 1 Measuring layout (side view) 5.2.3 Field frequency The standard field frequency of

For the procedure of sequentially changing input images, the input signals shall be changed just before the display luminance is changed and the measurement shall be carried out when the measured image is displayed.
