It’s official: LCD monitors have gone mainstream.

Swiftly falling prices have caused worldwide shipments of LCD (liquid crystal display) monitors to more than double in the last year. Sales reached a record 2.9 million units in the second quarter of this year, according to market research company Display Search.

The company, which closely follows the computer display market, reported second quarter shipments were 23 percent higher than those in the first quarter and 131 percent higher than the second quarter of last year. As a result, LCD monitor shipments now make up 12.4 percent of the worldwide desktop monitor market on a unit basis, the company said.

Behind the booming interest in LCD monitors is a sharp price reduction. The average price of LCD monitors dropped by 16 percent from the first quarter to the second quarter.

Prices are expected to continue falling, bringing more good news to consumers. With the third quarter just ending, Display Search expects to find average sales prices to have fallen a further 20 percent.

Display Search also noted that many people are choosing to update their desktops by buying LCD monitors to replace their outdated CRT screens, rather than replacing their PC systems.
