LED segment display and manufacturing technique thereof

The invention relates to an LED segment display and a manufacturing technique thereof. The LED segment display includes a nixie tube housing and a PCB circuit board which are assembled together; hollow display windows are formed in the nixie tube; the plurality of display windows from a displayed graph or character; the PCB circuit board has light-emitting LED lamps corresponding to the display windows; the nixie tube housing includes an outer member and an inner member embedded in the outer member; the display windows are formed in the outer member; a plurality of channels corresponding to the display windows formed in the outer member are formed in the in the inner member; and the inner member is installed and fixed on the PCB circuit board firstly, and then is combined with the outer member through glue pouring. The manufacturing process includes: pouring glue into the outer member and performing baking; and combining the PCB circuit board and the inner member together to form a semi-finished product, and
