Although probably start from ten years ago, flexible displays have become electronic products and technology conference, but until the regulars today, we still never in the shop window seen real product however, this time it really coming: Taiwan's industrial technology institute has authorized displays and electronic paper production business partners of photoelectric use their new technology,This year might have flexible display panel products. Work the new technology developed court, perhaps will change the world it is the Wall Street journal invites independent panel of experts to evaluate. This is called the multi-purpose flexible electronic boards display materials FlexUPD new technology, as in the past four months has won back-to-back R&D magazine and the Wall Street journal R&D 100 technology innovation award 2 awards.The two awards worldwide only to those with the most creative and the invention of the breakthrough to improve the effective and low cost of flexible display panel production efficiency, apparently can meet these two conditions. The current several flexible display panel production technology although have different features, but also have some similarities,for example they all need in a hard and flat hard base adhesive layer of flexible substrate, again in flexible substrate placing made and placed electronic components and various panels, wired up then put the finishing flexible display panel taken from the base.Did so because, in fine presentation components in production processes of flexible substrate needs precise fixed location and flatness, only to calculate the error in microns to electronic components not dislocation between. This requires flexible substrate to firmly and base; combine And in making the flexible display panel after completing taken from the base of the process, and asked for substrate can easily from base.It is difficult to reach such contradictory requirements, stripping flexible panel often can have a slight when the deformation, lead to electronic components lines reduced, and the yield of dislocation, piece will cost soared. Flexible displays of course will change the world, but need more mature technology to just go. For this problem, the past has had some solutions.For example in the hard base vacuum deposition a layer of film, in this layer of film is placed on substrate and components, and finally even the film together; tear away Or use laser whole layer evaporation from flank with convenient stripping rigid base, etc.But these methods or too time consuming, or likely to cause damage, so it has not always given the wide application of commercialization FlexUPD, by contrast, technology to be much more accessible. Industrial institute LiZongMing lee from the bread and the process of doing embellish inspired in embellish, like baking bread and add a layer of easy tear between the intermediary materials, let embellish baking bread can smooth out without damage, worker grinds court spokesman said.Embellish bread is Taiwan a thin like paper pancakes. Embellish bread skin is very thin, the creators are skillfully laid the soft dough in hot stove plate with, the instant molding, embellish skin neither bread, and can quickly with pot was removed. Besides material itself, another key is in furnace plate makers, will first before precausions group with a layer of oil.Materials and chien-sheng LiZongMing feel soft electronic group substrate process will imitate the process. FlexUPD through in the process of production to add a layer of called the special materials from shape layer, to meet the production flexible display conflict requirements. In production, from shape layer through flexible substrate and fixed stickers to facilitate production base of the accurate alignment; And in complete all the process after, simply cutting process, can easily put flexible panel and base apart.Flexible display panel in the production process, the function and from shape layer cake paper cups like cups. Using the FlexUPD technology display panel production line, first by vacuum evaporate plating or nets seal, in the hard way base form a layer of slightly larger than panel area from shape layer, usually in the second methyl benzene together for raw materials.Then from shape layer in the epoxy resin coating, adhesive, than the area from besmear shape layer a few bigger.Then they can be placed in adhesive flexible substrates, into conventional semiconductor until connect the power supply, and the signal lines so far. In the production process after completing will enter cutting need only from the edge of the fractal layer along cutting, the entire block can be flexible display panel easily from base. Hard base from shape layer stickers and flexible substrate has a variety of materials, stripping down optional flexible display panel may and from shape layer bonding together, also may be separated from it; And the base residues, can use laser stickers to gasification. This technology focus is to seek and develop optimal performance materials should not only can withstand the semiconductor devices production process of high temperature and all kinds of chemicals, have enough strength enough flexibility and the light transmittance high enough.Since 2006, development process spent researchers over four years, solve the problem, some more than 100 patent application, and the final effect is fairly satisfactory.The flexible display technology for process provides a simple and top-ranking solution of the Wall Street journal one of evaluation experts British communications commission chairman William Webb said resources of science and technology. Besides can greatly improve the yield of flexible display panel outside FlexUPD technology, and a very attractive characteristics: traditional display panel makers don't need to purchase additional equipment can be applied this technology.It can not only for a flexible LCD panel, organic light emitting diode (OLED) display panels and electronic paper panel will also benefit from this technology. Compared with the traditional display of flexible displays have many advantages: unit area is lighter and does not damage easily, etc. In a recent show, we have seen the use of this technology to produce ultra-thin TFT LCD panel, flexible use of polyimide substrates, thickness only 0.1 mm, bend radius can less than 5 centimeters, can experience the million times bend without damage. It seems like that scroll type PDA or ebook reader is no longer a distant, flexible displays the hanging also will soon become a reality. Before 2012, we have good can see that style of flexible display device, it could very well be a refreshing ebook reader; And in all the IT products, there is no more suitable than IT used to welcome the New Year.Maybe we can be like carrying ordinary newspapers so it curling or folded in half. |
