The media recently reported that Samsung will abandon large-size OLED technology and switch to QLED technology. Orient Securities believes that QLED is a kind of LCD liquid crystal technology, which can only slightly slow down the process of LCD being replaced by OLED, but can not change the industry trend that OLED will completely replace LCD.
Core point of view?
QLED only improves the backlight technology of LCD: the so-called QLED quantum dot panel still uses LCD liquid crystal technology, but the backlight technology is different from the blue LED excitation phosphor method of the usual LED backlight, and the QLED backlight uses the blue LED to excite the quantum dots to generate white light. Quantum dot backlights produce more brilliant colors. QLED backlighting is not a new technology. Sony launched the “Teli TRILUMINOS†technology used in high-end models in 2013. The essence of this technology is QLED backlighting.
OLED is a revolutionary innovation relative to LCD: OLED is self-illuminating, compared with LCD technology such as QLED, it has insurmountable advantages such as low power consumption, light weight, high contrast, foldable bending and high refresh rate.
Display technology is a major innovation driver of consumer electronics. OLED features will drive a new round of consumer electronics innovation in the areas of foldable terminals, transparent displays, virtual reality VR products, and automotive displays.
OLED will eventually replace LCD: The current RGBOLED adopts LTPS backplane, and the cost increases rapidly with the increase of size, which is more suitable for small-sized panels. OLED of IGZO backplane technology is expected to solve the problem of large size. Orient Securities maintains its previous report forecast that OLED screen mobile phone shipments will increase from 200 million in 2014 to 1.36 billion in 2020, CAGR up to 41%; OLED TV shipments are 67% CAGR from 2014 The 77,000 units will grow to 16.5 million units in 2020.
Given that the cost, size and ease of installation of lithium ion battery are reducing, to rely on renewable solar energy and Solar Lifepo4 Battery can be an optimal option for any residential, commercial or industrial. The back-up battery should eliminate virtually all outages, and using Li-ion should last at least five years. UFO 48V 200Ah home Lithium Battery is designed with new lithium iron phosphate (LFP) battery technology. It is operating at 48 volt, which offers a power capacity of 9.6kWh.
