[iMiD 2017] AP Systems, Find FMM answers through USPL

/in , , /by

At iMiD 2017 in BEXCO, Busan on 28th, AP Systems announced that it succeeded in developing 1000ppi FMM with USPL (ultra-short pulse laser).

Since FMM plays a role of depositing pixels and RGB organic materials, FMM serves as a factor that determines resolution and yield of OLED. At present, FMM is mainly manufactured by etching method. This method has a problem that a shadow phenomenon due to the precision, thickness, and weight of the fine pattern occurs, in order to solve this problem, various FMM manufacturing processes such as laser processing and electro-forming have been developed.

Among these, laser processing method has an issue of forming burrs around pin-holes due to the thermal effect caused by laser irradiation. These burrs increase the shadow interval of the FMM, which causes overlapping of patterns during RGB organic deposition, thereby degrading the resolution of the OLED.

AP Systems has developed a burr-free laser process that does not have burr phenomenon and further controls the taper angle.

The Burr-free laser process is a short-time irradiation of unidirectional pulses at a constant number of times, since the laser is not continuously irradiated, it minimizes accumulated heat energy and prevents burr formation. In addition, by controlling energy of the laser, it accumulates energy and forms taper.

In this way, AP Systems explained ‘they produced FMM with various shapes of fine pin-holes such as square, diamond, and polygonal shapes, as well as 1170ppi FMM’, and ‘’We also developed large-area FMM manufacturing equipment with USPL method’.

AP Systems also added ‘multi-beam and USPL is equipped for FMM manufacturing equipment so that it can improve productivity and realize UHD’.

Since the launch of the Galaxy Note4 in 2014, the OLED resolution has remained at the QHD level yet. In order to manufacture an OLED having a high resolution (UHD level or higher), it is necessary to solve various technical problems faced by FMM. Accordingly, it is noteworthy how USPL technology of AP Systems will affect the future OLED market.

LG Electronics will have a strategic premium smartphone equipped with OLED in the 2nd half this year.

LG Electronics will apply OLED FullVision, an 18: 9 aspect-ratio OLED display completely filling the entire screen panel to a strategic premium smartphone in the 2nd half. The size of the display is 6inch wide- larger than 5.7 inches of the previous model LG V20, but the size of the product is rather smaller by reducing the size of the bezel.
Based on the display technology obtained from LG OLED TV, which has been recognized as the world’s best premium TV, LG Electronics plans to provide a different level of visual experience of smartphone; “With OLED technology which has been accumulated over the years, we have completed the differentiated high-class design of the subsequent strategic premium smartphone.”
In the LG Electronics’ strategic premium smartphone, the “bezel bending” technology has been embedded in, which makes the circuit and insulating layers at the bottom of the panel bent backwards and the lower bezel reduced by about 50% compared to the previous model V20. Toughened glass on the outer layer of display is curved all around edge and is smoothened along the contour line of the backside to emphasize a sense of unity on the design,

OLED FullVision has a QHD + (1,440×2,880) resolution and an optimized screen quality algorithm equipped with a color gamut of 148% based on sRGB, default color space for photography and internet, and 109% based on digital cinema color standard DCI-P3.

LG Electronics stated that OLED FullVision should present a deep and vibrant screen with excellent contrast ratio and fast response time will provide a full-fledged screen without afterimages for fast-moving video or games.

LG Electronics also said, “The durability of the display has been upgraded as well, considering the portability of smartphone. OLED Full Vision is stronger than glass substrate displays because it is based on P-OLEDs with pixels placed on plastic substrates,”; “Cutting edge technologies are embedded in such as Corning®’s latest tempered glass ‘Gorilla® Glass 5’ and shatter-resistant technology that prevents the glass powder from scattering when the glass breaks. ” LG added.

Additionally LG Electronics said, “We have applied hardware and software technology to enhance durability. Also encapsulation technology that minimizes oxidation by covering the pixels with a protective film to prevent air contact, and pixel scanning program that identifies heavily used pixels and reduces their power consumption. OLED technology has minimized the burn-in phenomenon that can occur on the display. ”

Joon-ho Cho, president of LG’s MC business director emphasized, “We will provide a high end smartphone with a different level of design and screen quality, integrating the world’s best display technologies proven by LG OLED TV.

<Source :LG Display Unveils Next-Generation Market Leading Technologies at CES>

LG Display is actively participating in the ‘CES (Consumer Electronics Show) 2017’ to be held in Las Vegas, the U.S., from January 5 to 8 to show more diverse products and next-level differentiated technologies.

LG Display plans to convey its purpose to achieve consumer innovation together with LG Display’s differentiated technologies under the slogan of ‘Our Technology, Your Innovation’, at its private showroom for clients in the Las Vegas Convention Center, from January 4 to 8.

Especially, LG Display will showcase new products that basically has superior picture quality and fulfill OLED’s next-level design and potential, as well as a variety of products that provide new future to customers with its own differentiated technologies.

 

■ Unveil the New OLED TV with Superior Picture Quality, and Extreme Design

LG Display will release its differentiated OLED TVs with unsurpassed picture quality and potential application and design.

During CES, it will also introduce a 55-inch transparent FHD display featuring the improved colors and more natural and transparent screen.
LG Display will showcase 65-inch and 77-inch UHD Wall Paper TV line-up with ultra thin and innovative design. It will also show off futuristic displays, including a 77-inch double-sided UHD display and 77-inch six rollable UHD commercial displays, which will open various possibilities of OLED with surpassed picture quality.

 

■ Constantly evolving IPS, Innovative LCD Technology

LG Display’s OLED(Organic Light-Emitting Diode) and a high-resolution technology IPS evolve further.
LG Display will show off IPS products with improved picture quality and price competitiveness by using WCG(Wide Color Gamut, a technology to provide a greater range of colors), HDR(High Dynamic Range, a technique to reproduce a greater dynamic range of luminosity), and high-resolution technical solutions.

Especially, IPS Nano Color at this show is LG Display’s own WCG technology that can express more accurate and vivid colors, using nano-sized wide color gamut.
It is increased with the addition of the strength of IPS OLED to offer high color accuracy. This show will apply it to a 65-inch UHD product.
