LG Display Claims ‘Quantum Jump’ in Performance of Quad HD 5.5-Inch LCD Panel for Smartphones

LG Display started mass production of a 5.5-inch Quad HD LCD panel for smartphones that is “a quantum jump” in color gamut, brightness, contrast ratio, touch functionality, power consumption and thin form factor, the company said in a Friday announcement. The panel will be used in LG’s “flagship” G4 smartphone to be unveiled at the end of April, it said. The panel uses “advanced in-cell touch” technology for better touch sensitivity “so that it can respond to touch commands even with water drops on the screen,” LG said. Its contrast ratio is 50 percent higher than previous Quad HD LCD panels, and its brightness increased by 30 percent without any increase in power consumption, it said. High-color-gamut LED technology built into the panel provides more accurate colors in red and green by combining a blue LED chip with red and green phosphors instead of combining the blue LED chip with a yellow phosphor used in conventional LED backlights, it said. LG Display estimates it achieved a 20 percent improvement in color gamut with this technology, the company said.
