Title:
MEASUREMENT METHOD AND MEASUREMENT SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/133113
Kind Code:
A1
Abstract:
Disclosed are a measurement method and a measurement system thereof, used to measure the contrast of a display device (01). The measurement method comprises: controlling the display device (01) to display a first image, and testing the brightness at a central area of the first image; controlling the display device (01) to display a second image, and testing the brightness at a central area of the second image; and determining the contrast. The first image and the second image both have multiple areas having different grayscale levels. The central area of the first image is an area having a maximum grayscale level in the first image, and the central area of the second image is an area having a minimum grayscale level in the second image. The measurement method and measurement system can use the same baseline to measure the performance of products, thereby eliminating the influence of an algorithm.
