    Can a 3D printer create an OLED TV?

    Just asking.

    • No and it makes no sense
      3D printer is making 3D objects out of some plastic pulp or clay or aluminum powder.
      OLED TVs are flat and thin (or curved and thin), pretty much 2D.
      3D printers make rather small objects - about handgun size.
      OLED TVs are 55 inch in diagonal.
      Search on google for "shapeways" what people do with 3D printing (e.g. klein bottle coffe mug)
      Just forget about printing electronics, ok ? focus on picture quality of OLED screens,
      Printing electronic circuits was a a dream of electrical engineering for edges. It works but very poorly - ink jet printed circuits have too high resistance and as such require higher currents and so are not very energy efficient.

      • DuPont Finds a Customer for Its OLED Spray Printing Process
        November 3rd, 2011
        DuPont announced yesterday it has signed a technology licensing agreement with a leading Asian manufacturer of Active Matrix Organic Light Emitting Diode (AMOLED) display products. The agreement will enable process technology developed by DuPont to be used in the company’s production of large AMOLED television displays. Terms of the agreement were not disclosed, including the name of the licensee.

        However, an extremely reliable industry source tells me that several months ago Dainippon Screen Manufacturing showed him a Generation 5 printer that DNS was building for Samsung Mobile Display (SMD) on an R&D contract. This becomes interesting if you know that Dainippon and DuPont have been working together for years on their OLED spray printing process, with DNS building the Gen 4 spray printer that DuPont has been using to develop its materials, display architecture, and process.

        So, it’s a good guess that SMD is the" leading Asian manufacturer" of DuPont’s press release. The only other likely candidate is LG Display, but LGD’s new Gen 8 fab will be making color-by-white displays, which are not an obvious candidate for DuPont’s spray printing process.

        DuPont has given multiple presentations and written multiple technical papers describing its spray printing process, which gets around the significant problems of using drop-by-drop inkjet printing for functional materials. DuPont’s argument that its process is also significantly less costly than existing processes is also convincing.

        "AMOLED televisions…are preferred by consumers for their superior performance, they are more energy efficient and the process technology we’re licensing allows them to be manufactured much more cost effectively," said David B. Miller, president of DuPont Electronics & Communications. "We look forward to helping make the promise of AMOLED television a commercial reality at a price point that is within reach for the mass consumer market." Despite DuPont’s expected cost savings, mass-market pricing is not a trivial objective.

        DuPont, obviously, isn’t a start-up with a clever technology and no sensible business plan. Indeed, DuPont expects to monetize its work not only by licensing the process but also by selling the materials it has optimized for the process. As William F. Feehery, global business director for DuPont Electronics & Communications, put it, "By licensing display manufacturers to make AMOLED displays using DuPont process technology, we will also build a business selling proprietary DuPont OLED materials."

        Let’s add some additional tidbits. During Samsung’s quarterly earnings call in late October, Samsung VP of investor relations Robert Yi said the company intends to introduce mobile devices with flexible displays during 2012. "The flexible display we are looking to introduce sometime in 2012, hopefully the earlier part," said Samsungs VP of investor relations Robert Yi. "The application probably will start from the handset side."

        Now, SMD has been showing flexible AMOLED prototypes literally for years, so the company could introduce such displays without using DuPont’s technology. In fact, last year Samsung purchased what used to be LiquaVista, the developer of electro-wetting displays, so Samsung has access to two display technologies that are well-suited for flexible substrates. But Samsung has been very successful with its line of Galaxy mobile handsets with AMOLED displays. If I were a betting man, I’d guess it is OLED that will supply the first curves for Samsung in 2012.

      • This report provides the most comprehensive view of the topic, giving detailed ten year forecasts by device type. The market is analyzed by territory, printed vs non printed, rigid vs flexible, inorganic vs organic, cost of materials vs process cost and much more, with over 200 tables and figures. Activities of over 1,000 leading companies are given.

        The report specifically addresses the big picture - including all thin film photovoltaics, relevant display technologies and much more. Importantly, it includes not only electronics which are printed, organic and/or flexible now, but it also covers those that will be. Realistic timescales, case studies, existing products and the emergence of new products are given, as are impediments and opportunities for the years to come.

        Over 3,000 organizations are pursuing printed, organic, flexible electronics, including printing, electronics, materials and packaging companies. While some of these technologies are in use now, with substantial growth in thin film photovoltaics for example, others such as thin film transistors, developed by over 500 organizations, are only becoming commercially available now. The benefits of these new electronics are numerous - ranging from lower cost, improved performance, flexibility, transparency, reliability, better environmental credentials and much more. Many of the applications will be newly created, and where existing electronic and electrical products are impacted, the extent will be varied. This widely referenced IDTechEx report brings it all together, with particular focus on applications and quantative assessment of opportunities.

        Market Size from 2012 to 2022
        IDTechEx find that the market for printed and thin film electronics will be $9.46 billion in 2012. 42.5% of that will be predominately organic electronics - such as OLED display modules. Of the total market in 2012, 30% will be printed. Initially photovoltaics, OLED and e-paper displays grow rapidly, followed by thin film transistor circuits, sensors and batteries. By 2022 the market will be worth $63.28 billion, with 45% printed and 33% on flexible substrates.

        However, the topic is even bigger than this with some conventional electronics such as conventional aSi Photovoltaics now migrating to being printed, to reduce cost, be available on flexible substrates and in larger areas. In addition to the above, forecasts for such markets are given, as is progress to print them.
        Lessons, Successes and Opportunities
        The report covers case studies of where printed electronics has been used, why and the results. It looks at new products that are imminently emerging and their prospects for success. The technical barriers and commercial barriers are listed and prioritized, as well as progress to overcome these.

        In particular, the following components are addressed, and for each one ten year forecasts are given, along with companies and their activities, case studies, impediments to commercialization and timescales:

        Logic and memory
        OLED displays
        OLED lighting
        Electrophoretic displays
        Electrochromic displays
        Electroluminescent displays
        Other displays

        Sentiment: Strong Sell
