The first big event - Touch panel in Taiwan "Touch panel and optical film process, equipment, material exhibition (Touch Taiwan)" on August 24th. Technology support, the ministry of economic affairs in Taiwan Taiwan institute the from published material, substrate, module, equipment to the application of 36 flexible display and a touch of scientific and technological achievements, construct the display from the "hard" to the "soft" needed for the key technology, complete technology solution for manufacturers. Taiwan industry institute 24 in Touch Taiwan 2016, published a number of flexible display innovative research and development, and won the "Gold Panel allow 2016" excellence award.
As OLED is widely used in mobile phone screen, Taiwan industry research institute for next generation of flexible display of OLED application successfully developed a series of related materials, from the OLED displays on base board, flip the traditional inorganic materials, mainly organic 350 c not yellowing soft transparent substrate, overcome the OLED panel reflective look not clear OLED high contrast thin circular polarized films, for OLED block water layer with high density OLED touch with high heat resistant transparent fill material and provide perfect protection of OLED panel folding and anti-scrape wear-resisting layer.
In equipment technology, Taiwan institute assisting system manufacturer for extensive pattern equipment for integrated development, and the ministry of economic affairs practice plan, research and development of A + quenching to roll the plate (R2S) pattern equipment is given priority to, collocation can be precise control of large slit coating equipment, coating thickness and develop soft mode light resistance, embossing, light resistance and filling materials such as the key material, and large areas of submicron mould manufacturing and electroforming technology, not only can improve material utilization and increase production capacity, but also provide A full solution of large area of sub-micron design application.
In addition, in view of the automation and testing equipment, Taiwan being pavilion the also exhibited a "non-contact measurement module resistance", by electromagnetic field and the coupling relations between the material, a non-contact measurement impedance characteristics, the object under test sample can avoid injury, measurement speed is quick, can measure under high-speed mobile impedance uniformity of the object under test, etc, can be applied to online testing process. In addition, "semiconductor Film thickness measurement equipment qualities Chek AS300" using broadband light source and the interference characteristics of a thin Film, to measure the spectral reflectance, can quickly and accurately positioning, image preview function, can obtain membrane layer thickness, the refractive index of the material and the extinction coefficient of the optical properties, Film thickness measurement scope biggest surge by tens of microns to 150 microns (microns).
In this exhibition, being pavilion key technologies:
350 c is not yellowing turn soft transparent substrate materials research and development of organic practices
Can be widely used in electronic and high temperature resistant soft soft substrate, Taiwan industry research institute have developed adding inorganic composition of soft transparent substrate, successfully overcome add too much inorganic materials will be mixed uneven, high strength, such as brittle and poor transparency problem, successfully let of nanometer grade inorganic particle mixing in the organic polymer materials, make the finished product with strength, rigidity, heat resistance, transparent and so on many merits. Institute a workers did not yellowing soft transparent substrate has high strength, light quality, resistant to 350? C high temperature, corrosion resistance, high light transmittance, durability and superior dimensional stability, excellent performance and comprehensive performance over the single material, more extends the application range in innovative materials.
High contrast thin circular polarized light
OLED panel color very bright eye, but often due to glance at the bottom of the metal electrode structure, reading, as well as the use of mobile phones in the big sun can't see clearly. Taiwan work being applied materials thin coating method to develop all round polaroid, outside on the OLED outer layer, can let the ambient light into not only the block caused by ambient light reflection, can effectively solve the problem of reflective metal electrode, significantly improve the contrast of the OLED panel. The circular polarized slice thickness is only 30 microns (microns), is a traditional polaroid 1/2 thickness, more resistant to 100? C process, through the 3 mm curvature bending test 100000 times, can be first used in the flexural products.
Folding and anti-scrape wear-resisting layer
Phone scratches will be labeled as a layer of protection, the traditional mobile phone plastic protection without resistance to bending, cannot be used in the future can flex panel or on the phone. Taiwan work being applied wet coating method (similar to paint), combined with ultraviolet curing method, developed resistance to bending and anti-scrape super wear resistant protective layer, provides perfect protection for the soft panel. The technology of process temperature < 80? C, has advantages of low production cost and process easily, the future could be applied to display in addition to optical coating can expand the application in building materials, furniture, more scratch resistant coating on the surface of the 3 C products, etc.
OLED touch with high potential transparent bridge resistance material
When OLED enters a deflection display applications, water vapor and oxygen block about OLED lifespan, Taiwan industry research institute developed with high heat transparent organic materials filled material, with only a small inkjet or screen printing will be 5-10 nanometers protection on the rubber seal film packaging 10 microns (microns) dust, for follow-up after hardening layer block water oxygen production provide a flat surface. Due to the high density and surface flat, block water oxygen process just for 2 or 3 way evaporation operation, significantly ahead of traditional inorganic membrane plating operation of 5 to 6, have to save time, save costs, low temperature process (90 c), in addition, by using organic materials, without solvent composition, more completely avoid solvent for OLED damage problem.
