Founded in 1972, Everlight Chemical, electronic chemicals in 1996 began working career, after 16 years of continuous research and development to establish independent technology innovation, has been able to supply LCD, LED, and the IC industry needs photoresist, a developer and slurry polishing process used, polishing fluid, cleaning fluid and other key chemicals. During the 2012 Taiwan FPD, Everlight Chemical district in Taipei Nangang Exhibition Hall I 816 booths featuring touch panel photoresist, LTPS TFT-LCD photoresist, COF flexible substrates with photoresist, AMOLED photoresist agents as well as LCD, LED with the developer and many other products.

Review of 2011, thanks to mobile phones, tablet devices robust AMOLED touch panel and process all types of photoresist process chemicals agents material contribution requirement, Everlight Chemical's electronic chemicals revenue growth of 16\\% compared with 2010, a substantial profit growth of 43\\%. Chen Wei Wang Everlight Chemical general manager, said the future will continue to launch in response to a touch panel and AMOLED process associated with the photoresist process chemicals r

Everlight Chemical general manager Chen Wei Wang.

Chen Wei Wang further noted that the work of the touch panel key Yongguang chemicals market for more than five years, has been able to supply the insulation layer and the protective layer of the touch panel with positive / negative type photoresist (EPL 300 Series & EOC 130/180 / 200 Series product), since the products have good Subsequently, transparency, hardness, developing and etching resistance properties, and high temperature resistance, humidity and other properties, the turnover bring significant contribution. In this exhibition will also be on display in touch with the relevant key photoresist chemicals, including black EK520 photoresist and EOC 200 series photoresist.

Black EK520 photoresist, due to a high sensitivity, good adhesion (> 4B), high surface resistance, high line resistance and excellent heat and chemical resistance properties, available at the touch panel protective glass; another EOC 200 series light blocking agents, used in the touch panel of the insulating layer and the protective layer of photoresist, with a high hardness (4H), good metal adhesion (greater than 4B), high transmittance (thickness 3.5μm, transmittance greater than 95\\% ) and other features, you can type with an inorganic base (KOH type) the developer and buffered (Buffer type) using developer. One of the EOC 210 and EOC 250 series photoresist, but also with the developer without TMAH metal ions.

Chen Wei Wang said that in addition to the layout of the touch industry, but also focus on the potential for future outbreaks infinite AMOLED market, AMOLED TFT LCD compared with a better color saturation, high brightness, high contrast, fast response, and other advantages, is the best smart phone applications display technology. Samsung and HTC and other mobile phone brands have switched leadership in introducing new smart phones have AMOLED display, DIGITIMES Research estimates that by 2014, global small and medium size (10 inches or less) AMOLED shipments will reach 465 million, 2011- 2014 compound annual growth rate will reach 70.9\\%.

Everlight currently corresponds to a key chemical in AMOLED, AMOLED panel has applications in process with the photoresist, including EPL 356 photoresist, which has a high resolution, good etch resistance, etc., used in the manufacturing process and the metal lines ITO graphical, also be used in the insulating layer (insulator). The ENPI 300 photoresist has good heat resistance, resist Overhang good angle, etc., used in the spacer layer (Pillar or Rib)

Chen Wei Wang said the low temperature polysilicon (LTPS) of TFT-LCD manufacturing process is one of the key technologies to enhance the panel process efficiency, so that the screen has a clearer, more detailed the picture quality, Everlight Chemical EPL 386 photoresist application of LTPS processes, with a high sensitivity, low power consumption characteristics, the process can improve the efficiency of the panel. In recent years many of the industry to launch a flexible display, FSR 110 has a high resolution photoresist (less than 5 μm), low exposure energy (high sensitivity), process latitude and other characteristics, and has a flexible and well adhesion, may be coated on a flexible substrate, mainly used in the LCD panel driver IC chip on film package COF (Chip on Film).
