'Actually, two or three years ago, Merck has begun to implement some of the center's work - to provide customers with innovative solutions to achieve OLED application development. 'Morgan OLED Division China General Manager Zou Minghao to the "China Electronics News" reporter disclose.
Because the OLED material and the liquid crystal material are very different, the liquid crystal monomers are mixed together in a certain proportion to achieve a uniform and stable liquid crystal morphology to form a mixed liquid crystal, which can be used after being tested and verified by a panel manufacturer. However, there are a dozen layers of material films for the OLED device. Each layer of film has a variety of materials to choose from, and different layers will interact with each other. Even the thickness of each layer will affect the performance of the final device, so it is difficult for panel manufacturers to find a suitable arrangement.
Due to the layer arrangement, film thickness, and supplier diversification, it is likely that this situation will occur: OLED material itself is very good, but due to its unsuitable role in the permutation and combination, let the manufacturer Misunderstanding that the performance of the OLED material is poor.
This is also plaguing OLED material manufacturers. Each OLED material manufacturer has limited resources, it is impossible to do all the materials, more often only the best materials, and different panel manufacturers have different device structures, the same material Getting feedback from different vendors may be very different.
Previously, Merck had encountered some of the above situations and felt deeply. Zou Minghao said that on the surface, there are only a dozen layers of material films for OLED devices, but there are multiple options for each layer of materials. The arrangement of different layers may have Thousands of species, if coupled with the effect of film thickness, theoretically there may be millions of permutations and combinations, so it is necessary to have a systematic laboratory to screen suitable materials.
According to reports, Merck OLED Technology China Center has a 2.5-generation OLED experimental line. Merck can produce OLED device samples according to sample materials provided by panel manufacturers, and conduct OLED photoelectric characteristics, life test.
Merck OLED Technology China Center acts as a connector for material manufacturers and panel manufacturers. The center will provide local customers with customized solutions for OLED application development and innovation, providing OLED device manufacturers with advanced devices and clean space. Customers can use This cooperation platform and Merck jointly create an ideal solution for OLED display products. Zou Mingji, for example, said that if the panel manufacturers light up the OLED samples, but the sample is half the screen performance than the Samsung S8, half the life, and the brightness is not bright enough. The color is not bright enough, etc. Panel makers hope to improve OLED performance and can propose some specific needs, and then together with Merck in the OLED Technology China Center to find the material and film structure that meets the needs.
In fact, not only Merck, South Korea, the United States, and Japan's OLED material companies have established similar OLED technology application centers. Zou Mingji pointed out that other manufacturers have set their OLED technology application centers in their own countries, and Merck is the most open, Merck. It is the first foreign-funded enterprise to establish an OLED technology center in China. This reflects Merck's dedication to the development of reliable, high-efficiency and high-purity OLED materials, and the support of customers to create innovative products to meet market demands.
