Abstract
The invention discloses an automatic curtain reeling type LED display screen. The automatic curtain reeling type LED display screen comprises a motor, a winding roller, a flexible circuit board with the top end fixed to the winding roller and a plurality of LED dot matrix units welded to the flexible circuit board. The dot matrix units are arranged on the flexible circuit board in parallel from top to bottom; the dot matrix units are completely contained in grooves in the flexible circuit board in a fixed mode; and the motor is in transmission connection with a winding shaft and is connected with a rotating speed adjustor. According to the automatic curtain reeling type LED display screen, the LED dot matrix units are fixed to the flexible circuit board and are contained through the winding shaft so that the automatic curtain reeling type LED display screen can be conveniently installed and carried. In addition, the motor is adopted for controlling, automatic curtain reeling can be achieved, and the area is controllable in size.
Description
technical field [0001] The invention relates to an automatic rolling screen LED display screen. Background technique [0002] The LED display screen controls the display mode of semiconductor light-emitting diodes. Its general appearance is composed of many light-emitting diodes, usually red, and the characters are displayed by turning on and off the lights. It has the advantages of high brightness, low working voltage, low power consumption, large size, long life, impact resistance and stable performance. The development prospect of LED is very broad, and it is developing towards higher brightness, higher weather resistance, higher luminous density, higher uniformity of luminous light, reliability, and full color. LED displays are widely used in advertising in sports venues, commercial applications, banks, securities, postal services, docks, shopping malls, stations, postal services, telecommunications, agencies, surveillance, schools, restaurants, hotels, entertainment an...
