16 Go to cover page 5.5. Chromaticity The color chromaticity is measured by a photometer (CA-210) at 1680x1050/60Hz mode and full white square pattern with contrast/brightness in default value. The x and y co-ordinates for 9300K, 8200K, 7500K, 6500K and 5000K. Preset mode shall be as below: 9300K Preset : 0.253≦x≦0.313 ; 0.268≦y≦0.328 7500K Preset : 0.269≦x≦0.329 ; 0.285≦y≦0.345 6500K Preset : 0.283≦x≦0.343 ; 0.299≦y≦0.359 5000K Preset: 0.314≦x≦0.375 ; 0.329≦y≦0.389 8200K Preset: 0.262≦x≦0.322 ; 0.277≦y≦0.337 5.6. Brightness The uniformity is determined by using a photometer (CA-210) to measure luminance on the center of screen after at least 30 minutes warm up. It shall be test at 1680x1050/60Hz mode and full white square pattern with contrast at default and brightness at max conditions. The values specified are at an approximate distance 20 cm from the LCD surface and at 0 viewing angle. The brightness at 6500K Preset mode shall be 240 cd/m² min. (M201EW02 V1) Note: Per panel specification, over the life of the product, variation of parameters specification Panel specification shall be maintained within reasonable limits. Check supplier quality inspection criteria for the detail information. 6. Environmental Requirements: 6.1.
