Light emitting diode (LED) display module capable of being installed easily and LED display device

The invention relates to the field of light emitting diode (LED) display devices, particularly to an LED display module capable of being installed easily and an LED display device. The LED display module capable of being installed easily comprises a frame and joint angle kits, which are used for fixing an LED display unit, the frame and the joint angle kits are in head-to-tail connection to assemble a seal installation space, a plurality of first installation holes arranged at an equidistance interval are arranged on the frame and are used for fixing the LED stripe-shaped display unit, the frame is a hollow structure with a stripe shape, and the frame is in sleeve connection with the joint angle kits. Accordingly, the plurality of first installation holes arranged at the equidistance interval are arranged on the frame and are used for fixing the LED stripe-shaped display unit, so that the problem that existing LED display units are installed in an unequal and unreasonable mode is solved, the frame which is a main part can be disassembled and in kit connection freely and is solid in whole, transparent, light in weight and suitable for different types of LED displays with different distances.
