Example Embodiment
[0046] Example 1
[0047] In this embodiment, a small-pitch LED display module is manufactured, and the specific process is as follows:
[0048] Select the LED light board with the model TVH2.5 installed on the mounting substrate, the LED dot pitch is 2.5mm, and the size is 200×150mm;
[0049] Use room temperature curing epoxy resin to fill the side of the LED light board away from the mounting substrate;
[0050] Secondly, use a PTFE plate (thickness 1mm) to press the side carrying the glue (pressure 0.04MPa), make the glue enter the gap between the LEDs and squeeze out the excess glue, and then cure ( 6h) To form a protective colloid, and then form a prefabricated module.
[0051] Remove the frosted board in the prefabricated module to form a small-pitch LED display module.
[0052] The performance of the aforementioned small-pitch LED display module was characterized, and the reflectance of the surface of the module was detected by a reflectance detector, and the visible light reflec...
Example Embodiment
[0053] Example 2
[0054] The manufacturing process of the small-pitch LED display module in this embodiment is the same as that in Embodiment 1, except that:
[0055] The thickness of the PTFE plate is 0.1mm, the pressing pressure is 0.005MPa, and the curing time is 0.5h. The performance of the aforementioned small-pitch LED display module is characterized, and the visible light reflectance is 1%.
