The invention provides a display equipment color depth test system and test method, and relates to the technical field of display equipment color depth detection. The test method comprises the steps that a test platform is built in a laboratory and comprises a signal generator, a plurality of test signals of different gray levels are sent to a to-be-tested display device, and after the test platform is built, the signal generator generates a gray level image queue and outputs the gray level image queue to the to-be-tested display device; the optical measurement equipment measures the illumination intensity displayed by the display equipment to be measured according to the gray level image queue to obtain brightness information corresponding to the gray level image queue, and the data analysis equipment obtains brightness and gray level relation information according to the gray level image queue and the brightness information; establishing a gray scale and brightness response curve according to the brightness
