Technical Field

The utility model relates to a display module assembly especially relates to a display module assembly with preferred structure yield.

Background

In a current direct view LED (dvLED) display device, after a LED panel is mounted on a driving substrate by Surface Mount Technology (SMT), two dispensing packaging operations are performed sequentially. The first time of black glue dispensing is for filling gaps so as to avoid crosstalk interference between the LED lamp panels, and meanwhile, the black glue dispensing device has the functions of fixing and improving contrast. The second transparent adhesive tape is applied to protect the LED lamp panel, so that the LED lamp panel has the functions of water proofing, dust proofing, collision proofing and the like. The above-mentioned twice glue dispensing operation is carried out on the light emitting diode lamp panel in sequence, namely, the on-line operation is carried out, and the operation time is long, so that the production time and the output efficiency are easily influenced. Furthermore, the black glue may be sprayed on the light-emitting surface of the LED lamp panel, and thus expensive plasma cleaning equipment is required for removing the black glue. In addition, the black glue and the transparent glue are in direct contact with the light-emitting diode lamp panel when being filled, so that the light-emitting diode lamp panel can be peeled off or the driving substrate can be deformed due to the shrinkage stress of the glue when the black glue and the transparent glue are solidified. In addition, after the glue is cured, if the led lamp panel is damaged or needs to be repaired, the rework becomes very difficult.

Therefore, a new display module is needed to overcome the above-mentioned drawbacks.
