Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are different kinds of flat panel displays. This list includes LCD, OLED and microLED display manufacturers.
LG Chem supplies display and optical films, polarizers, printed circuit materials, and toners.It also supplies LCD polarizers, which are multi-layer sheets of film applied to the top and bottom surfaces of TFT-LCD panels to transmit the light from the backlight unit through the panel, and 3D FPR (film-type patterned retarder) film, which enables three-dimensional viewing.
In December 2016, the company sold the Chemetall Surface Treatment business to BASF for $3.2 billion. [33] [34] [35] In January 2017, the company acquired the Jiangli New Materials Science and Technology Co. lithium business for $145 million. [36] In October 2019, the company formed a lithium joint venture with Mineral Resources. [37]
Samsung and LG-Display showed 55-inch OLED-Television devices at CES-2012. But both companies had to delay their mass production. Also AUO, Sony and Epson will start AMOLED-TV production in 2014. [22] In June 2013 Samsung announced the Korean availability of a 55-inch curved OLED HDTV. Priced at 15 million Korean won (around $13,500).
The companies declined to say how much of the EnergyX Series B that the consortium is funding. Posco, though, will have the right to invest in other lithium projects that EnergyX develops ...
However, a team of scientists at the Joint Center for Energy Storage Research have just discovered a fast magnesium-ion solid-state conductor that will go a long way towards making non-flammable ...
A magnesium–air battery has a theoretical operating voltage of 3.1 V and energy density of 6.8 kWh/kg. General Electric produced a magnesium–air battery operating in neutral NaCl solution as early as the 1960s. The magnesium–air battery is a primary cell, but has the potential to be 'refuelable' by replacement of the anode and electrolyte.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
