The invention relates to a
display device with the functions of removing dust and blocking light. The
display device comprises a display screen, a support plate, a control panel and a support base, and further comprises a dust removal mechanism and two light blocking mechanisms, wherein the dust removal mechanism comprises a first motor, a rotation shaft, a transmission shaft, a fixing block, a dust removal box, a transmission
assembly and two sliders, a dust removal
assembly is arranged in the dust removal box, the dust removal
assembly comprises a movable box and two movable units, a
power unit, a swing rod, a connecting rod, a hinge rod and a suction
nozzle are arranged in the movable box, each light blocking mechanism comprises a light blocking box, a rotation assembly and a telescopicassembly are arranged in each light blocking box, and each rotation assembly comprises a second motor, a roller and light-shading cloth. For the
display device with the functions of removing dust andblocking light, through the dust removal mechanism, dust covering the display screen can be removed, thus the phenomenon that dust accumulates on the display screen, further, the watching of people is influenced, is avoided, therefore, the practicability of the display device is improved, meanwhile, through the light blocking mechanisms, light-shading work can be carried out on the display screenfrom two sides of the display screen, and thus the phenomenon that the screen reflects light, consequently, the watching effect is influenced, is avoided.
