Global sales of plasma televisions surged 95 percent in the April-June quarter from a year earlier to 2.2 million units, bolstered by robust sales at Japan's Matsushita Electric Industrial Co. (MC), U.S. research firm DisplaySearch said.

Plasma display panel (PDP) TVs took a 5 percent share of the worldwide TV market in the second quarter in unit terms, up from 4 percent in the first, the company said in a report dated August 24.

Demand for flat-screen TVs, such as PDP TVs and liquid crystal display (LCD) TVs, is surging as falling prices lure consumers who want to trade in bulky picture tubes for large, sleek televisions.

On a revenue basis, PDP TV sales grew 57 percent from a year earlier as price declines outpaced increases in the average size of televisions sold, DisplaySearch said.

Plasma TVs accounted for 20 percent of the global TV revenues in the second quarter, up from 18 percent in the first.

Matsushita, the maker of the Panasonic brand, cemented its No. 1 position in the PDP market by increasing its share to 28.3 percent in the second quarter from 21.5 percent in January-March.

South Korea's LG Electronics Inc. ranked second with a 17.1 percent share, followed by its home rival Samsung Electronics Co. Ltd. with 13.6 percent and Dutch Philips Electronics (PHG) with 10.3 percent.

LCD TV sales jumped 135 percent in the second quarter to 9.4 million units, accounting for 22 percent of the global TV market in unit terms, DisplaySearch said earlier this week.
