Claim 0:
1. A display test apparatus, comprising:
a measuring apparatus configured to accommodate a first display device including a first display panel and a second display device including a second display panel; and
a calculating device connected to the measuring apparatus,
wherein the measuring apparatus is further configured to provide a sample pixel value to the first display device and the second display device, measure a first color coordinate value associated with a first display image of the first display panel in response to the sample pixel value, and measure a second color coordinate value associated with a second display image of the second display panel in response to the sample pixel value, and
the calculating device is further configured to generate a first parameter of the first display panel in response to the first color coordinate value, generate a second parameter, different from the first parameter, of the second display panel in response to the second color coordinate value, generate a target color coordinate value in response to the sample pixel value, generate a first mapping table in response to the first color coordinate value, the first parameter and the target color coordinate value, and generate a second mapping table, different from the first mapping table, in response to the second color coordinate value, the second parameter, and the target color coordinate value.
