TC TECH receives patent approval in Taiwan that strengthens the protection of the company’s technology platform
TC TECH Sweden AB (publ) has received a patent approval in Taiwan for the patent application ”Device and method for heating a Mould or Tool”. The approval in Taiwan follows earlier approvals in Japan and China for the same patent family within electromagnetism, that strengthens and extends the patent protection for the company’s general technology platform. The patent will be valid until the 13th of June 2032.
TC TECH’s technology platform makes it to possible to use induction (electromagnetism) to heat up, emboss and cool down detailed objects made of plastic, or other materials, with nanometer precision. The approved patent will protect the basic use of electromagnetism in the technology platform.
“This patent approval is encouraging as it extends the patent protection for our technology platform on an important Asian market. Corresponding patent applications have been filed in several other important markets in Asia, Europe and North America,” says TC TECH CEO Alexander Luiga.
Initially, TC TECH has developed a production system for the manufacturing of a new generation of light guide plates (LGPs) that can substantially reduce the energy consumption in edge-lit LCD displays, while at the same time improving the picture quality. Edge-lit LCD displays are used in the majority of all mobile phones, tablets, laptops, computer displays and TVs on the market today. TC TECHs technology platform also has the potential to be used within several additional application areas.
Two production systems for the manufacturing of LGPs have been delivered in Taiwan, and they are now being used in demanding industrial conditions. This makes it possible to continuously improve the production system for optimal performance during high-volume manufacturing.
LCD still the largest in displays
The dominant display technology on the market today is LCD displays where lighting is done with LED lights and the light is spread with LGP (Light Guide Plate). Most of the displays are expected to be based on LCD in the foreseeable future. There are other display technologies such as Quantum dots, which also use LGP, as well as OLED that do not use LGP to spread the light in the display. There is ongoing development in these display technologies. The following comparison table between a High Precision (HP) LCD display and an OLED Flexible clearly shows the strength of each technology. It is TC TECH’s assessment that with the help of High Precision LGP, LCD displays can continue to be a very large part of the overall market
|Comparision HP LCD (with LGP) and OLED Flexible|
|HP LCD||OLED Flexible|
|Display resolution||Excellent < 800 ppi||Good < 400 ppi|
|Display out to the edge||Excellent||Excellent|
|Viewing angle color rendering||Excellent||Good|
|Viewing angle Luminance/brightness||Good||Excellent|
Flexible LGP with a thickness of 0,125 mm
Automated production with TCP 150
TC TECH Sweden launches RTS 150, Roll-To-Sheet for automated manufacturing of advanced pattern in TCP 150. RTS 150 enable continues production of double sided pattern with a thickness down to 0,15 mm or less depending on the pattern and material. A roll last around 24 hours and can be replaced within a few minutes.Â The system can handle both film substrate with or without double sided protective film. The possibility to produce film substrate without protective film provides great benefits both economically and environmentally. The protective film which is normally placed on both sides of the film substrate and coated with a glue add a significant cost and cannot be recycled, it will be waste and burned or deposited.
The system is adapted to customer-unique authentication systems after the double sided pattern is produced. It can for example be a vision system for automated inspection. Then the product is ready for next step and can be handled either automated or manually.

TC TECH achieves temperature increases of more than 100°C per second
From its very start, TC TECH has emphasized the rapid and exact heating made possible by the company’s IPR-protected technology. A temperature increase of 200°C has been achieved within two seconds, with the heated area controlled within 0.1 mm and with temperature variations below one degree over the entire surface. This rapid heating, in combination with TC TECH’s other IPR-protected solutions for stamping technique and controlled cooling, has what it takes to melt and pattern plastic films or plates down to nano-level.
The R&D department in Spånga has been questioned whether it would be possible to reach the temperatures required for steel to harden. The very first trial resulted in a temperature above 900°C being reached within seven seconds of heating. This means that TC TECH’s technology achieves the standard temperatures used for the hardening of steel – in fewer seconds and with higher exactitude than has been possible to date. TC TECH will now continue to evaluate the scope for its technology in the area of hardening of metals. The heated area can be defined in the same way as when an LGP is produced, and it is possible to heat complex forms such as TC TECH’s logo below with partial hardening of nothing but the heated areas. To achieve optimum quality in the steel, a controlled cooling process following the heating is of utmost importance.
TC TECH’s head of R&D, Jan Jäderberg, comments on the outcome of the tests: ”the trials delivered as expected, which was of course very satisfactory. This paves the way for our ambitions to expand into application areas outside the production of LGP (Light Guide Plates), although this will remain our core business for several years ahead.”
TC TECH´s technology boasts 0.125 mm LGPs with wedge
The LGP industry relentlessly strives for continued product development to achieve improved performance, reduced thickness and lower costs. The majority of the Light Guide Plates currently available on the market are 0.3 mm or thicker. Mobile phones are favoured with the thinnest LGPs, whereas TV sets use LGPs that are considerably thicker – there is actually a wide range of thicknesses depending on what is expected from the end product. The thinnest LGPs available on the market today are limited by what existing techniques may achieve without impairing quality and/or strength. TC TECH has successfully developed LGPs for mobile phones that are half as thick as those used today. TC TECH’s system has produced LGPs that are 0.125 mm thin and equipped with a wedge that allows for a thicker LED – the LED otherwise limiting the thinness of the LGP.
0,125 mm thick LGP with 0,25 mm wedge
TC TECH has performed promising tests with patterns on LGPs down to 0.05 mm thin, and is now ready for the next step on the road towards energy-saving LGPs with the lowest possible environmental impact throughout the production process.

TC TECH’s unique technology makes protective films superfluous
Current technologies based on extruded film used for the production of so-called Light Guide Plates (LGP) require a film that is protected by plastic film on both sides, up to the moment of processing the LGP. This is, of course, to eliminate damages and impurities before the process. However, with TC TECH’s production method for High Precision Light Guide Film (HP LGF) no protective film is needed, which means lower costs and reduced environmental impact – as the removed protective films, including their glue residues, are always discarded after removal. With TC TECH’s unique technology, any potential damages are repaired and eliminated when the double-sided pattern is applied.
In TC TECH’s Roll to Sheet equipment (RtS) the plastic film is cleaned before the process, which means that the risk of impurities impairing the efficiency of the nano-pattern is eliminated. TC TECH’s RtS is designed for the use of LGF without protective film, but can also handle the removal of protective films.
Roll to Sheet – Automatic handling of plastic film entering and exiting a TCP 150. A roll of film substrate (with or without protective film) is fed into the system. If protective film is used, it is automatically removed on both sides. The film substrate is deionized and vacuumed/cleaned.
