The electronic packaging materials industry belongs to the new materials industry in the strategic emerging industries that the state supports and develops.Electronic packaging materials are specific functional materials used in the packaging process of electronic components, whose main role is to form a system of electronic devices, the implementation of the function of fixing, supporting and protecting the formation of the overall structure at the same time, to meet the device's electrical conductivity, heat dissipation, corrosion resistance, insulation, vibration damping and optical properties of the device, and other performance requirements, belonging to the manufacture of electronic components and electrical and electronic manufacturing of one of the key materials, in the electronic materials, occupies an important position.Electronic packaging materialsAs one of the main categories of electronic packaging materials, electronic adhesives have benefited from the rapid growth of downstream and end-use applications, and the market demand has been expanding in recent years.According to QY Research data, in 2021, the global electronic adhesive market size reached 42.8 billion yuan, is expected to grow to 70.5 billion yuan in 2028, compound annual growth rate (CAGR) of 7.3%.

LED backlight module for liquid crystal display light source, broad market space driven by the continuous development of electronic packaging materials marketDue to the liquid crystal material itself does not have light-emitting properties, the main part of the liquid crystal display screen is generally composed of liquid crystal display panel and LED backlight module.

LED backlight module as an important driving light source for TFT-LCD liquid crystal display, its development is mainly driven by the development of the liquid crystal display industry and terminal field.

LED devices for LCD backlight modules are further developing in the direction of high power, and the power of a single LED bead reaches 2-3W, which puts forward higher requirements for the reliability of silicone encapsulation materials in terms of light aging, heat aging, and barrier properties, and continues to push silicone encapsulation materials towards the high end step by step.LED full-color display has significant advantages in the field of large-size display, small-pitch LED display technology continues to penetrate

LED full-color display is composed of RGB three-color LED lamp beads, featuring high brightness, large size and mature technology development.At present, LED display screen has realized high definition, high resolution and stable performance for a long time, and is widely used in advertising and media, cultural performances, sports venues, high-end meeting rooms, traffic control, high-end auto shows, security, night view economy and other fields.In recent years, with the continuous maturity of LED packaging technology and the rapid decline in cost, ultra-high-definition and high-density small-pitch LED full-color display technology is developing rapidly.Spacing refers to the distance between the centers of two LED lamps, small pitch LED full color display is generally between 1-2.5mm. Small-pitch full-color LED display screen has the advantages of high brush and high brightness, realistic picture quality, long life, no splicing seam, high durability, etc. As the pitch continues to shrink, the pixel density increases, and the resolution is also greatly improved.At present, small pitch full-color LED applications to government, public security, energy and transportation fields. In the future, with the improvement of manufacturing technology, the penetration rate of commercial market and civil market will grow further.
