Large screens based on organic light-emitting diodes not yet widely used, mainly because of the high cost of OLED-panels. LG and Samsung, which are considered the leaders in the development of appropriate technologies, offer 55-inch TVs with OLED-screen.
Somewhat unexpectedly, the general background of the young company Kateeva, present equipment for printing OLED-panels sufficiently large size. Characteristically, the method also reduces the production cost by 30% in comparison with a liquid crystal screen .
Kateeva managed to elegantly solve the problem of LED destruction under the action of oxygen and moisture, print is made in a nitrogen environment. Also, the developers have provided equipment weighing sensors and mechanisms to prevent uneven application of LEDs on the substrate. Printing device - YIELDJet - capable of processing glass sheet large enough to out of it later you can cut six 55-inch panels for TVs.
Incidentally, YIELDJet is usable for the production of flexible displays. Price LED printer is not specified, but about six months Kateeva necessary in order to deliver the equipment to the customer, and about a year to run it at full capacity. Related Products :
