Outdoor LED display screen based on concave-convex lens visual persistence curtain with scraping brush

Abstract

The invention discloses an outdoor LED display screen based on a concave-convex lens visual persistence curtain with a scraping brush. The outdoor LED display screen structurally includes a front curtain board, locking pin sockets, a lens disc lifting brush frame, a left-hand clamping block, a luffer board frame, LED lamp bead boards and a pressing buckle horizontal bar frame. According to the display screen, the front curtain board cooperates with the lens disc lifting brush frame, through lifting of a concave-convex lens, the concave-convex lens is in lifting sliding linkage with a slide-rodjacking column, pulls a scraping brush shaving board, presses against and fits the front curtain board for snow water removal and cleaning, when the front and rear portions of the LED lamp bead boards are subjected to mapping and imaging, one layer is displayed on the front curtain board through image formation, mappings at the rear ends are converged into a concave mirror slotted disc, then a second layer is stereoscopically formed at the front end of the display screen through the magnification effect of a convex mirror block, the animated visual persistence effect is achieved, people can conveniently adjust the crystalline lenses in the eyes, there is a sense of distance, a fascinating feeling is presented, visual fatigue can be relieved, and the flexibility of machines inside the display screen is optimized.

Description

technical field [0001] The invention relates to an LED outdoor display screen based on a concave-convex mirror visual persistence scraping screen, which belongs to the field of LED display screens. Background technique [0002] The LED light bar is installed in the square outdoor display screen, and it will form a full-color viewing effect. Most of the display racks are attached to the second to third floors of the walls of high-rise buildings, so that people can intuitively see the displayed pictures and images when they look up. Information is a convenient enterprise publicity and information exchange equipment. The disadvantages of the current common technology that need to be optimized are: [0003] Since the placement of outdoor LED lights needs to be packaged with a screen to facilitate imaging and mapping, and to prevent rain, snow, and fog from affecting the screen, the protection of the screen is strong in conjunction with the display. However, the simple plane mapp...

Problems solved by technology

[0004] Aiming at the deficiencies in the existing technology, the purpose of the present invention is to provide an LED outdoor display screen based on the concave-convex mirror visual persistence scraping screen to solve the problem of packaging the screen for the convenience of imaging and mapping due to the placement of outdoor LED lights, and to prevent rain, snow and fog The weather affects the screen, so the protection of the screen and the display effect are strong, but the LED's simple flat mapping is not observable enough, and the visual aesthetics are single, which will become the effect of tired eyeball lens to avoid viewing, so that the content of the display screen is easy to be ignored and has no sense of novelty. In addition, the partial rain, snow and fog curtain can seal and block the LED lamp bead board, but the accumulation of thick snow and long-term rainy days will cause high humidity in the template, and the direct penetration of water vapor will cause internal disconnection, which will cause the heavy screen to collapse the top structure of the display screen , leading to the problem of deformation and compression of the light board accident
