Description

Magic color lamp display device Technical Field The utility model belongs to the technical field of display equipment, and particularly relates to a multicolor lamp display device. Background In recent years, with the rapid development of LED display technology, the magic color lamps (such as WS2812, SK6812 and other integrated RGB beads) are widely used in intelligent lighting, advertisement display screens, stage lighting, wearable devices, holiday decoration, game peripherals, architectural beautification and other scenes due to the advantages of single-line control, rich colors, rapid response, flexible serial connection and the like. However, before the magic color lamps are applied to a large amount of end products, especially in the process of mass production of lamp strips, lamp panels, etc., how to quickly and efficiently perform power-on detection, communication integrity verification and color control consistency test on each lamp bead becomes a key factor for limiting the product yield and quality. In the large-scale application of the magical color lamp, whether the lamp beads can normally receive data is verified. That is, it is verified whether the communication between the beads of the magic color lamp and the communication between the beads and the micro control processor are successful, so as to know whether the data return between the beads is complete. Currently, the detection of the magic color lamps is mainly performed by a manual or machine vision device. In manual observation and detection, an operator manually triggers a test program to observe the state of the lamp beads in sequence. The detection mode is strong in subjective judgment and is not suitable for mass production line production. The mode of adopting camera + image recognition system is with the camera gathering lamp area image, and through algorithm analysis lighting effect though higher, the effect is better than manual precision, but this kind of detecting method is in the ambient light interference big, to the recognition algorithm requirement high in the testing process, can appear being difficult to the single lamp anomaly of location especially to high density lamp battle. Based on the above, there is an urgent need to provide a multicolor lamp display device capable of simultaneously detecting the multicolor lamps, so as to solve the technical defects in the above-mentioned technology. Disclosure of utility model The utility model aims to provide a visual multicolor lamp display device aiming at the defects of the prior art, so that the visual degree and interaction convenience of multicolor lamp display are improved, and the detection efficiency and the detection accuracy are further improved. In order to achieve the above purpose, the present application implements the following technical scheme: A display device of a magic color lamp comprises a main control module, namely a magic color lamp test circuit connected with the main control module, wherein the magic color lamp test circuit comprises at least 2 magic color lamps which are connected with adjacent magic color lamps in cascade, the main control module comprises a micro control processor, a clock unit and a display unit which are connected with the micro control processor, the magic color lamp test circuit inputs a driving signal group output by the micro control processor and locks each control signal into different magic color lamps, and the display unit displays the color corresponding to each magic color lamp according to the driving signal group. The technical scheme has the following technical effects: The multicolor lamp display device ensures the stability and consistency of color display of the multicolor lamp through time sequence control, and improves the overall display effect. Whether the single lamp is lighted or the combination of multiple lamps, the color transition is fine and uniform, and richer visual experience is brought to the user. The main control module of the display device is stably and reliably connected with the multicolor lamp test circuit, and the failure rate caused by poor connection is reduced. Meanwhile, the display unit is introduced, so that the testing process is more visual, and a user can quickly know the current testing state by observing the display content, so that the testing efficiency is improved. Secondly, the technical scheme of the application also has good expandability. The main control module can preset a plurality of detection modes, and a user can flexibly select according to actual requirements. Furthermore, the application can meet the requirements of different application scenes. As a further improvement of the display device of the present application, the color lamp includes a data input terminal DIN and a data output terminal DOU, and the micro control processor or the data output terminal DOU of the color lamp adjacent to the color lamp inputs the driving signal group to the data input termina
