It is precisely for this reason that Samsung has repeatedly stressed that it will never consider the launch of the OLED panel TV, but will aim at the development of QLED (qqd) and MicroLED.
QLED TV is the main technology of Samsung TV at present. Its principle is to use inorganic materials instead of organic materials in OLED, so as to improve the durability of sub pixels.
Samsung announced today (July 12th) that all 2018 of its QLED quantum dots television received the "non burning" certification of the German science and technology magazine video, which was done jointly by video and connect Testlab.
Burn in is called "scorch screen" in the context of Samsung, which shows that no matter how the image switches, there is always a lingering, sticky pixel mark on the screen, mainly due to the long viewing of the same image or scene.
In order to be repeatable, the test organization designed a set of 72 - hour test method with reference to industry and international standards, and the TV was displayed in black and white chessboard, with changing text and intermittent flickering.
In order to avoid the bad points in the static image test, 10 nite's dark grey image was used to detect whether the scotoma was in the bright state.
During this period, Samsung QLED TV did not have any problems such as shadow, ghost, memory effect, and screen, but in the same environment, other brands of television have not been able to carry it.
Video said that in theory, Samsung's QLED TV can always maintain power on and off without burning the screen.
Previously, the well-known television rating agency, Rtings.com, also tested the city's mainstream television with 10 minute image preservation methods, and Samsung had a full mark on the quality and loss of the image.
