LED bracket, LED bracket array, LED device and LED display screen

A light emitting diode (LED) bracket array, comprising a plurality of LED brackets, wherein each of the plurality of LED brackets comprises a Printed Circuit Board (PCB) circuit substrate and an insulating material, wherein the PCB circuit substrate comprises at least two electrode regions electrically insulated from each other;

• each of the at least two electrode regions comprises a top electrode region, a side electrode region and a bottom electrode region;
• the top electrode region and the bottom electrode region are connected into an integrated structure by the side electrode region;
• the side electrode region is a side surface sunk from an outside to an interior of the PCB circuit substrate;
• the side electrode region is partially coated by the insulating material;
• an upper end surface and a lower end surface of the insulating material do not exceed an upper surface and a lower surface of the PCB circuit substrate in a thickness direction thereof, and a thickness h of the insulating material is less than a thickness H of the PCB circuit substrate.
