Abstract:
1. A method for measuring reflective intensity of display surface, which comprises: placing a first display and a second display in the same ambient, dividing the display luminance of the second display into N levels, wherein N being an integer greater than 1, placing light-shielding object only to the first display to surround the peripheral of surface of the first display, the first display and the second display being placed side by side; at a luminance level of the N luminance levels of the second display, adjusting the display luminance of the first display so that the first display and the second display are perceived by the human eye distant from and in front of the first display and the second display as having the same observed luminance; obtaining a luminance value L2 for each of N luminance levels of the second display measured by a luminance measuring device such as luminance meter, and obtaining a corresponding luminance value L1 of the first display measured by a luminance measuring device such as luminance meter, when the first display and the second display are perceived by the human eye as having the same observed luminance; obtaining the reflective intensity of the display surface in the ambient based on a difference between the measured luminance value L1 of the first display and the measured luminance values L2 of the second display when displaying.
