Taken together, the market share of the three companies in small and medium size displays, like the ones used in phones and tablets, represents 21.5%, more than Sharp's 14.8%, or Samsung's 11.9%.
Many screen innovations have come out of the trio like Hitachi creating the IPS-LCD display, for example, Toshiba's HD LCD screen and flexible OLED display, or Sony's recent WhiteMagic technology, so we could be in for more pleasant surprises as consumers when their R&D departments start sharing knowledge and projects.
Both Samsung and LG, on the other hand, are scaling back on large screens, like those for TVs, and shifting focus to the booming mobile display market, while Sharp's displays are being green-lit by Apple, so the more competition, the merrier for us spoiled users.
Toshiba's flexible OLED display
Hopefully their work will inject some healthy dose of competition in this market, where Samsung is a few laps ahead of everyone else with its upcoming Super AMOLED HD mobile displays.
