Abstract

The invention discloses a shutter type display screen, which comprises a plurality of shutters, a plurality of supports, a rotation unit and a transmission unit. A plurality of displaying units are arranged in the shutters, the leaves are axially arranged on the supports, the transmission unit is connected with the leaves, and the rotation unit controls rotation of the leaves through the transmission unit. The shutter type display screen realizes functions of a display screen and a rotation function of the shutters and functions of folding and unfolding of the integral shutter type display screen, accordingly, irradiation quantity of sunlight can be regulated and space utilization rate is increased. The shutter type display screen is applicable to display halls, curtain walls of halls of banks, multi-media advertising boards of buildings and the like, requirements for light regulation of customers, requirements for visual field transparency and requirements that the shutter type display screen can be used as art lights at night or multi-media advertisements can be met.

Description

Technical field [0001] The invention relates to a display screen, in particular to an LED louver type display screen. Background technique [0002] The display screen used on the traditional building facade is composed of unit boxes. Its driving circuit and power supply system are all installed in each unit box, so the screen has a large volume and weight, occupying the outer surface of the building curtain wall. If the screen is not turned on, the black screen will affect the appearance of the building facade. It affects the lighting and ventilation of the room behind the screen, and the heat generated by the screen is not suitable for dissipating, and the screen is made of steel plate, which is easy to rust and is inconvenient to maintain. So its use has been greatly restricted. [0003] In response to the above problems, LED louver screens have been developed on the market. Although LED louver screens solve the above-mentioned room lighting, ventilation and heat dissipation pr...
