Abstract

The invention discloses an outdoor LED display screen and a fabricating method thereof. The outdoor LED display screen comprises a flexible substrate, wherein one side of the flexible substrate is sequentially provided with a first silica gel layer, a flexible circuit board layer and a second silica gel layer. The flexible circuit board layer comprises a plurality of display units, each display unit comprises a flexible circuit base board, the front of which is provided with a plurality of LED lamps and the back of which is provided with a circuit module used for controlling the LED lamps. The fabricating method of the outdoor LED display screen comprises the steps of: firstly, laying the first silica gel layer on the flexible substrate; secondly, laying the flexible circuit board layer on the first silica gel; and thirdly, laying the second silica gel layer on the flexible circuit board layer. The outdoor LED display screen has small volume, light weight, convenient package and transportation, convenient installation, good water prevention and simple fabrication.

Description

technical field [0001] The invention relates to an LED display screen, in particular to an outdoor LED display screen. Background technique [0002] The existing LED display screen integrates the light-emitting diode die into a dot matrix module or pixel unit, that is, a display unit, and then connects several display units together, and at the same time is equipped with a power supply device. Each display unit is made of metal material. The formed square box is used as a carrier, and the display unit is fixed on the box to form an LED display screen. However, such LED display screens are not convenient for transportation. [0003] In order to solve the above problems, the Chinese patent application number 200820188745 discloses a LED display screen, which includes several LED video screen units, each LED video screen unit includes a fixed bracket, a plurality of LED light-emitting tubes installed on the fixed bracket and A controller fixed on the LED luminous tube. A gro...
