Company News >> Thick and small size OLED production capacity LGD or R & D OLED panel mask 16th,Sep,2017
                                    (LG Display; LGD) intends to independently develop for the OLED panel mask (Shadow Mask). The mask is an important part of the panel resolution, the technical threshold is quite high, Samsung Display (Samsung Display) also has not yet related technology, must rely on Japanese imports.
According to the media, the industry has said that LGD has ordered a special metal industry to create a mask of invisible steel (Invar), try to develop masking technology to reduce the degree of dependence must be imported from abroad.
Different from the large-size OLED panel process, small and medium size OLED panels must be used for evaporation of the mask, the more openings on the mask, the higher the resolution of the panel produced.
But the current panel panel used by the OLED panel mask all imported from Japan. Dominate the small and medium size OLED panel market Samsung display to the big Japanese printing (DNP) procurement, LGD is to Toppan Printing (Toppan Printing) order.
LGD will start from the second half of 2017 E5 production line production of small and medium size OLED panels to 6-generation line substrate to calculate the monthly production capacity of about 15,000, and in the second half of 2018 the same capacity of the E6 production line will also be invested Operation, that is, within two years will be more than 30,000 monthly production capacity, the demand for the mask will increase.
The industry believes that, due to the future market demand for the mask fear of tight, LGD will decide to challenge to try to develop independently.
It is understood that by the end of 2018, the mask leading manufacturers of large Japanese printing production capacity has been completely Samsung display appointment, until the Samsung display began to supply large-scale Apple (Apple) OLED panel, the mask supply and demand will be more tight. If the LGD and letterpress printing can not work together to improve the mask production, stock problems may occur.
There are also industry that LGD is in the glimpse of virtual reality (VR) device market. Because LGD orders the constant steel is electroforming (Electroforming) method of the necessary materials, made by electroforming mask can show VR device requirements of high resolution.
Unstable steel has a very small coefficient of thermal expansion, also known as Invar, is not susceptible to temperature expansion, theoretically can produce a higher resolution than the UHD panel.
However, large Japanese printing mask method for the Etching (Etching) way, organic matter through the mask will be due to the incident angle problem, can not show better than the QHD level resolution. And therefore Samsung display from many years ago began cooperation with the Korean manufacturers, the development of electroforming method of masking technology, in advance for the VR era to prepare.
LGD in the small and medium size OLED panel business competition advantage far behind Samsung, even the big customers Apple was also Samsung away. But LGD if the first step by Samsung to develop a high-resolution OLED panel for the VR device, have the opportunity to regain market position. Because many years after the VR market opportunities unlimited, then the VR device panel demand will surge.
