Stage Introduction: Stage's software and hardware are designed and developed based on the definition of measurement projects in . Measurement projects include: 1. Luminance starting characteristic measurement 2. Luminance, related color temperature 3. Luminance uniformity measurement 4. Chromaticity uniformlessness measurement 5. Contrast ratio measurement 6. Color gamut coverage measurement 7. White balance difference measurement 8. Viewing angle measurement 9. Break-make ratio, light leak, black electricity steadiness measurement 10. Remaining image measurement 11. Response time and gray scale response time At the same time it can satisfy the needs in about average luminance measurement Hardware Motion Characteristics: Optical measurement instrument is driven by motor, which can move linearly along X axis (left and right), Y axis (up and down) and Z axis (front and rear) in three dimensions. When measuring viewing angle, measured LCD can rotate within 90¡ã along ¦µ direction and within ¡À90 along ¦Èy direction. Measurement distance is in accordance with the needs defined in : three times as HDTV's height and four times as SDTV's height.
