Abstract: An LED display, includes a mounting frame, at least one LED display panel and at least one separate power control box, with the LED display panel connected to the mounting frame, the separate power control box electrically connected to the LED display panel. The mounting frame includes transverse rods, longitudinal rods, and a connection block with two connection surfaces, with an 90° angle between the surfaces, two transvers rods and two longitudinal rods head-tail connected, one connection surface connected to the transverse rods, and the other connected to the longitudinal rods. A support pole is provided between two transverse rods along a length direction, with a support column on the support pole and extending from back to front, with a first control box connection hole on above of the support column. The display can meet requirement of easily stitching multiple LED display panels and achieving an ease usage.

Abstract: The invention discloses an objective and quantitative detection method for amblyopia by electroencephalogram (EEG). The method comprises the following steps: firstly, carry out binocular dichoptic viewing display, then design a visual evoked stimulation paradigm, establish a brain-computer interface platform, build a test interaction interface, next determine an amblyopia EEG quantitative index. By using a suppression coefficient (SI) to describe the binocular suppression relationship, quantify the degree of amblyopia, and finally obtain amblyopia detection result feedback, where the computer interaction interface module presents a final amblyopia detection result to realize feedback of a user. The operation is simple and rapid, the applicability is high, and the indexes are objective and quantitative.
