LED display packaging technology analysis

Time:2018-11-28 Views:133

As one of LED packaging products, LED display screen has quickly become the mainstream force of outdoor media due to its huge area, module control and assembly, high brightness, energy saving and energy-saving advantages.The market is more and more strict requirements on products, so the LED display manufacturers are expected to work hard in the technology.Now let‘s learn the packaging technology of LED display screen.

LED packaging requirements for display applications:

1. Optical requirements: high brightness, brightness uniformity, optical roundness, optical uniformity, etc.;

2. Design convenience: the appearance of the lamp body cannot reflect light; the appearance of the lamp body should be all black; the smaller the size, the better.

3. Operation convenience: welding resistance, deformation resistance, structural robustness, anti-static ability, etc.;

4. Reliability requirements: high weather resistance, low decay;

LED packaging enterprise technology added value analysis

Who can fully meet the above requirements, whose technology added value is more obvious, for example, Japan and Asia can better meet the above requirements than domestic packaging enterprises, its technology added value of the product price is much higher than the domestic packaging enterprises.In order to enhance the added value of technology, the primary task of domestic enterprises is to establish a strict technology research and development and product manufacturing system, which is the basis of enhancing the added value of technology of packaging enterprises.Fortunately, at present, some domestic enterprises have realized this and strengthened the construction of manufacturing and technology research and development system.

LED packaging enterprise technology added value reflected

Technology added value can be divided into two parts, basic technology added value and breakthrough technology added value.

1. Added value of basic technologies

Applicable conditions: have modern packaging equipment, mature packaging technology, stable supply of high-quality raw materials, modern testing equipment enterprises.

Packaging basic technology added value is:

A. High efficiency in product development and production capacity to meet basic market requirements;

B. Have a good understanding of existing processes, materials and equipment, and can match them reasonably.For example, the establishment of a "technical information base", the market needs such parameters as luminous Angle and brightness, what materials, what process can achieve or how to achieve the most economic, which should be available before the market demand;

C. Perfect quality control system, including "effective" manufacturing quality control system, "raw material quality light control system" before the manufacturing process, and "reliability guarantee system" that absolutely supports both;

2. How to add value to breakthrough technologies

Applicable conditions: the added value of basic technology has been achieved, and it has computer simulation model and disciplines involved in the industry, such as enterprises with complete talents in physics, materials, microelectronics, chemistry, optics and so on.

LED display packaging breakthrough technology added value:

1. Change the existing product structure so that the product index exceeds the needs of the basic market and promote the expansion of the market field;

2. Changed the existing raw materials, introduced new materials, exceeded the basic market needs, and promoted the expansion of market areas;For example, CREE has developed ceramic substrates, which has promoted the overall quality of LED lighting market to a high level. Due to the enhancement of added value of technology, the price of its products has naturally increased.

3. Change the process, improve the efficiency, reduce the overall cost, establish the packaging enterprise‘s own technical barriers, etc., can be regarded as an important embodiment of the added value of breakthrough technology.

LED display packaging determines the quality of LED display products.LED display requirements will vary depending on the environment they are used in. At present, LED display can challenge more and more extensive outdoor environment.LED display technology will determine the use of LED display surface.
