Abstract

The invention relates to an angle testing device. The angle testing device comprises a base, a connecting arm assembly and a mounting frame assembly. The connecting arm assembly comprises a connectingarm and a first rotating shaft which are connected with each other, and the first rotating shaft is rotationally arranged on the base. The mounting frame assembly comprises a mounting frame and a second rotating shaft, the second rotating shaft is rotationally connected with the connecting arm, and an included angle is formed between the second rotating shaft and the first rotating shaft. The mounting frame comprises a frame body and a plurality of mounting plates, the second rotating shaft is connected with the frame body, each mounting plate is provided with a mounting surface deviating from the frame body, the mounting plates are slidably connected with the frame body, and gaps are formed between the surfaces, deviating from the mounting surfaces, of the mounting plates and the frame body. According to the angle testing device and the display screen system, the left-right visual angle and the up-down visual angle of the display screen can be respectively tested, the angle testing precision of the display screen is improved, the visual angles of the display screens with different thicknesses and different lengths can be conveniently and stably tested, and the angle testing precision of the display screen is further improved.

Description

technical field [0001] The invention relates to the technical field of angle testing of LED display screens, in particular to an angle testing device and a display screen system. Background technique [0002] At present, the equipment for testing the angle is generally an integrating sphere, and the integrating sphere can only test a single lamp bead or a unit PCB board, which cannot meet the requirements of the entire screen angle test, and is greatly affected by the space. [0003] For LED displays, the existing full-screen angle test is generally a compass test, with a certain area as the center point, spreading to the left and right, recording the angle coordinates to be tested, and then manually moving the display screen to test the angle coordinates. The test data obtained by the test method is relatively simple, resulting in low test accuracy; in addition, the existing shelf for placing the display screen has limited space, and the display screen with a thick bottom s...
