Monitor screenmaker LG Display on Thursday filed patent infringement charges against rival and fellow South Korean firm Samsung, the news agency Yonhap reported.

The challenge involves seven alleged infringements of OLED (organic light-emitting diodes) screen technology used in Samsung's tablets and smart phones, including its Galaxy-S and Galaxy Tab 7.7 range.

LG, the world's second largest producer of flat-screen televisions, has demanded an undetermined amount of compensation.

Samsung, which is the world market leader in televisions, mobile phones and memory chips, said it was examining the charges. The company said it would not hesitate to submit a counterclaim, Yonhap reported.

OLED technology allows higher contrast imaging, and also means screens use less energy. It also means phones and tablets can be thinner.

Both companies are fighting for dominance in the OLED market. In July, Samsung accused employees at LG of having stolen its OLED technology.

Samsung is also embroiled in a bitter patent dispute with iPhone- and iPad-maker Apple.
