问题     LG Display, the world’ s second-biggest flat-panel display maker, is betting big on large-scale OLED television panels, brushing aside industry scepticism about the chances of the technology displacing mainstream liquid crystal display.
    OLED, or organic light-emitting diode, panels use ultra-thin, lighter technology to produce higher picture quality and lower power consumption than LCD screens. They feature on Samsung Electronics’ Galaxy smartphones and tablets.
    LG aims to steal a march in the potentially lucrative market on crosstown South Korean rival and world leader Samsung Display, which is instead focusing on improving LCD panels for ultra high-definition TVs.
    The diverging strategies reflect the mixed views about the future of OLED technology, long touted by industry watchers as a potential game-changer for the $94bn global TV industry but which remains clouded by doubts about its commercial value because of high production costs and technological challenges.
    Behind LG’ s aggressive investment to expand OLED production capacity lies the belief that demand for OLED TVs will take off once they are more affordable.
    "LCD has no future. The Chinese can make even ultra high-definition TVs at lower costs," says Oh Chang-ho, senior vice-president of LG’s OLED TV development division. "We cannot win this price war. For survival, we have to make products that they cannot make."
    Sony launched the world’ s first commercial OLED TV in 2007 but the Japanese company was surpassed by Korean rivals. However, mass producing large OLED TVs is difficult and more costly. Samsung and LG rolled out 5 5-inch full-HD(high definition)curved OLED TVs last year but the hefty price tag—roughly $15,000—deterred consumers.
    LG reckons it is finally in a position to cut costs, thanks to breakthroughs to boost production efficiency and resolve colour distortions. It plans to introduce curved ultra high-definition OLED TVs as large as 77 inches this year.
    The company is convinced OLED can breathe new life into consumer demand because the technology, best suited for flexible display, allows TVs to be made in all sorts of shapes. OLED panels are easier to bend than LCDs because they work without a backlight.     LG has recently developed an 18-inch Tollable OLED panel as well as the same-size transparent OLED panel and is confident that it can develop an Ultra HD flexible and transparent OLED panel of more than 60 inches by 2017.
    But LG is in the minority with its confidence in the budding technology. Its rivals remain sidelined by concerns that OLED may go the way of plasma—once promising technology that has been expensive to develop and ultimately not widely adopted.
    Samsung Display has opted to push the technological boundaries of LCD panels with high-margin ultra high-definition TVs capable of displaying four times the resolution of existing HD TVs.
The phrase "rolled out"(Line 3, Para.7)can be replaced by______.
选项 A、got out
B、spread
C、launched
D、tumbled
答案C
解析 语义题。“roll out”有“铺开；滚出；推出(新产品)”之意，联系上下文推知，“三星和LG”与“55英寸的全高清曲面OLED电视”应该是“发行，推出”的关系。选项中，C项launched意为“发行”，符合文意，故正确。
