Abstract

The invention relates to an LED power supply box and a display screen, the LED power supply box comprises a box body, a closed accommodating cavity is enclosed by the box body, the box body is provided with an inner surface and an outer surface which face opposite directions, and the inner surface defines a part of boundary of the accommodating cavity; a power supply which is arranged on the innersurface and is positioned in the accommodating cavity; and a heat dissipation piece which is arranged on the outer surface and located outside the containing cavity, and the heat dissipation piece discharges heat generated by the power supply to the outside of the containing cavity. External liquid and dust cannot penetrate through the box body to enter the accommodating cavity, so that an erosion effect on the power supply is avoided, and the service life of the whole LED power supply box is prolonged. Meanwhile, the heat dissipation piece is located on the outer surface of the box body andlocated outside the containing cavity, the heat dissipation piece has good heat dissipation performance, and the defect that heat dissipation of the closed containing cavity is inconvenient is effectively overcome. And moreover, the heat dissipation piece can bear stronger external impact capacity, so that the applicability of the LED power supply box to different working environments is improved,and the LED power supply box is ensured to always have good heat dissipation performance.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an LED power supply box and a display screen including the LED power supply box. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode) display screen is a kind of display screen, which is composed of small LED module panels and is used to display various information such as text, image and video. LED display integrates electronic technology, computer technology and information processing technology, and is composed of LED dot matrix. The modular structure is used for display control, so that the lamp beads can be turned on or off to replace the screen display content such as text, animation, picture or video. The LED display has the advantages of bright colors, wide dynamic range, high brightness, long life and stable and reliable operation. LED displays are widely used in commercial media, cultural performance markets, sports venues, information disse...
