The invention relates to a novel traffic signal countdown display screen comprising a waterproof box body. The upper part of the front surface of the waterproof box body is provided with a cap brim. The front surface of the waterproof box body is provided with an LED dot matrix display module with moisture-proof, salt-fog-proof and anti-mold functions. The display module is composed of a shell, a mask and a display unit. The display unit is composed of an LED, a printed circuit board and a drive chip. The internal part of the waterproof box body is provided with a switching power supply and a main control board. The switching power supply is connected with the display module and the main control board via power wires. The main control board is connected with the display module via a flat signal cable. The novel traffic signal countdown display screen is powerful in function, simple in structure and stable in operation. Traffic signs, traffic information and warning pictures can be displayed so that the effect of propagandizing can be realized and drivers and pedestrians can be prompted to notice traffic safety and road traffic conditions; besides, traffic signal countdown can be displayed so that the drivers can be prompted to prepare in advance, crossroad vehicle passage rate is enhanced and vehicle stagnation time is reduced.
