>> Apple OLED panel order competition violent Samsung material suppliers to prepare for a comprehensive 21th,June,2017
Samsung Display (Samsung Display) used in Apple (Apple) 2017 new iPhone OLED panel material selected day near the recent related materials industry have entered the state of preparation, panel materials industry, said OLED panel material because of subtle changes affect life And the efficiency of Apple's use of multiple materials is not high, the current suppliers are waiting for thin ice to stand out with the selected crossroads.
Korean media ET News reported that Apple's new iPhone OLED panel material in 2017 is expected to begin to decide the supplier in September to October, Samsung display stakeholders said the R & D time will be in accordance with customer requirements in advance or delay, as the panel specifications will With the customer to market time to decide.
Apple in October 2011 after the introduction of iPhone 4s, the new listing in September, Apple in March 2016 launched the iPhone SE is a parity model, to infer after the iPhone 6s after the new iPhone, is expected to be in the Launched in September, and 2017 OLED panel with the new iPhone is expected to be listed during this period.
Korean industry experts said that the panel materials industry researchers are sacrificing the summer vacation, research and development of samples, OLED panel materials for repeated testing, the current OLED panel material composition is in the light layer (EML) and common layer, to find the best chemistry Material, thereby maximizing the efficiency and longevity of the luminescent layer.
Samsung Electronics (Samsung Electronics) since August 19 began selling Galaxy Note 7, equipped with OLED panel material composition, and other flagship models Galaxy S7, Galaxy S6 similar, which, light-emitting layer of red phosphorescence Host by the Dow Chemical (Dow Chemical supply, Green Phosphor Host is supplied by Samsung SDI (Samsung SDI), which is responsible for Idemitsu Kosan.
In addition, with the majority of phosphorescent dopant patented UDC, is responsible for the supply of red phosphorescence and green phosphorescence, blue part of the use of fluorescent dopants, by the light production is responsible for the dopant trace of the material injected into the Host, Luminous efficiency, and adjust the color.
The panel material industry has pointed out that the luminescent material emits light through the transition of electrical energy. In the light emitting layer, the electronically moving electron transport layer is called the cathode, and the electric transport layer carrying the hole is called the anode, And the hole in the light-emitting layer will meet when the light, and the amount of energy to transmit light will determine the luminous color, the wavelength of light to the shortest blue light, followed by green light, red light the longest; when the shorter the wavelength, the greater the energy.
Materials industry, said the production of OLED industry is not only solely responsible for a single layer, but the production, including the luminous layer, the common layer of all materials, Samsung will sometimes be out of the industry to distribute outsourcing orders. As for the Samsung display in the supply Galaxy S series OLED panel, according to different market characteristics, determine the different color density of the material, like the mainland market preference red, they may choose to emphasize the red material portfolio.
