Apple's new OLED mobile phone panel market ecological add variable

Apple's new generation of mobile phones is expected to adopt organic light-emitting diode (OLED) panels. The market regulator believes that in addition to Samsung monitors that have already produced OLED mobile phone panels, other manufacturers are currently not mass-produced. Now, who is supplying them, in fact, the variables Still more.
International Data and Information Corporation (IDC) market analyst Chen Jianzhu pointed out that the current global panel factory production of mobile phone OLED panels only Samsung display, mass production of OLED TV panels only Lejin display.
Although other panel makers have begun to build an OLED panel production line for Apple's next-generation mobile phone OLED panel, it will take at least one year to two years to mass production. Whether the quality meets Apple's demand remains to be observed.
Chen Jianzhu said that Samsung OLED mobile phone panels have been put into the market for many years, so the OLED panels of other panel manufacturers will be favored by Apple. The first is that quality must keep up with Samsung.
He analyzed that, according to the current technology, the low-temperature polycrystalline germanium (LTPS) panel of the OLED panel below 15 inches is used as the back sheet, and the organic material is evaporated, the yield is higher, but the OLED panel larger than 15 inches uses indium gallium oxide. The zinc (IGZO) panel is a backing plate coated with organic materials with high yield.
He explained that the small-size OLED panel adopts red, green and blue (RGB) 3-color vapor-deposited organic materials, which is technically no problem, but the large-size OLED panel has no way to adopt 3-color evaporation, so only white vapor deposition can be adopted. Match color with color filter (CF).
He bluntly said that Apple has two or three suppliers of purchased components. The new generation of mobile OLED panel suppliers should initially be supplied to Samsung, which has already produced OLED mobile phone panels. It is a simple sale; the second stage is other supply. The commercial production of OLED panels is in volume production. Apple and its joint development of the required OLED panels, but now it is too early to talk about quality and yield.
He admits that even if the panel factory outside Samsung sells OLED mobile phone panels more than one year later, two years later, it is still unknown whether the quality can keep up with Samsung. Apple can't use it without asking for quality.

Superhard network knowledge small science:
Organic Light-Emitting Diode (OLED) is also known as organic electro-laser display (OLED). It is a different type of illumination principle than liquid crystal display (LCD). OLED was discovered by the Chinese-American professor Ching W. Tang in the laboratory in 1983, and the research on OLED was carried out. OLED display technology has the advantages of self-illumination, wide viewing angle, almost infinite contrast, low power consumption, and extremely high reaction speed. However, the price (large display panel), life, and resolution cannot match the LCD monitor.
Organic light-emitting diodes can be classified into monochrome, colorful and full-color according to color. Among them, the preparation of full-color organic light-emitting diodes is the most difficult; according to the driving method, passive (Passive Matrix, PMOLED) and active (Active Matrix, AMOLED) can be classified. ).
Although there have been rumors in the market that OLED screens will gradually replace LCD screens as display screens for mobile smart devices in the future because of their thinness and power saving features, but from the current market feedback information: oled screens in "color deviation", "lighting" Technical problems such as brightness and resolution are still plagued. In addition to Samsung's oled screens used in its flagship mobile phones, other smartphone screens with oled screens are inferior to high-end LCD screens.
