Sony is reportedly ceasing development of its organic light-emitting diode (OLED) TV sets in order to focus on liquid-crystal display (LCD) panels with Ultra HD, or 4K, resolutions.

OLED is a display technology which has proven popular in the mobile realm, finding its way into the majority of Samsung's Galaxy smartphone range including the Galaxy S5, but has struggled to make the break into large-format displays. This is largely due to the complexities of scaling up the production process to sizes suitable for home TVs. Unlike LCD, which covers a white light source with layers of coloured panels that can be switched on and off to produce images, each pixel of an OLED display produces its own light and can be switched off independently. The end result is a low-power display with extremely high contrast, offering true black reproduction where LCD can only manage a level of grey.

Companies including Samsung and LG have launched OLED-based TVs, but Sony has been lagging behind its rivals. Now, Nikkei reports that the company is abandoning OLED development altogether in order to focus instead on Ultra HD displays based on LCD technology - providing four times the resolution of a standard Full HD TV.

Sony has not commented on the paper's report, but with the company rumoured to be looking to make up as much as 50 per cent of its overall TV product line with Ultra HD sets it seems likely that its development focus has indeed shifted.
