The utility model relates to a uniform light field screen optical parameter detection device. The device comprises an illuminometer, a compensation device and an optical tester, wherein the compensation device and the optical tester are arranged in front of an LED display screen to be detected; the compensation device comprises a support, a lamp installation structure installed on the support and a plurality of LED lamps distributed on the edge of the front side of the lamp installation structure. The light-emitting surface of the LED lamp faces the LED display screen to be detected, and the brightness of the light-emitting surface is adjustable; and a lens of the optical tester faces the LED display screen to be tested. The device is simple and controllable, and enables the environment illumination of the LED display screen area to be measured to be uniform and to be changed within 1 +/-10%. 本实用新型涉及一种均匀光场屏幕光学参数检测装置，该装置包括照度计、设置在待测LED显示屏前方的补偿装置和光学测试仪；所述的补偿装置包括支架、安装在支架上的灯具安装结构及分布在灯具安装结构前侧边缘的多个LED灯具；LED灯具的发光面面向待
