An LED display screen automatically controlling light barriers comprises an LED display screen box body (1), LED lamps (2) and the light barriers (3). A light collecting panel (4) is disposed above the LED display screen box body (1). The light barriers (3) are disposed on every row of LED lamps (2). A light collecting unit (5) is disposed on the light collecting panel (4). A light signal collected by the light collecting unit (5) is transmitted to a light processing unit (6) for processing, and the processed signal controls the light barriers (3) to be adjusted. An included angle between the each light barrier (3) and a horizontal direction ranges from 0 degree to 60 degrees. A power supply (7) provides voltages to the light collecting unit (5), the light processing unit (6) and the light barriers (3). The power supply (7) and the light processing unit (6) are disposed inside the LED display screen box body (1). The upper side of each light barrier (3) is a rough surface, and the lower side of each light barrier (3) is a smooth surface. The LED display screen automatically controlling light barriers has a reasonable design, can automatically adjust the light barriers (3) when outdoor light is intense, and therefore ensures that the display effect of the LED display screen is optimal. |
