LG must consider the G4's display as one of its main attractions, because the company's launching it weeks before the device's debut. The South Korean electronics maker has announced that it's begun mass producing its next flagship device's 5.5-inch QHD LCD panel. LG says the 1,440 x 2,560 resolution screen has 538 pixels per inch and boasts a 120 percent color gamut, which enables it to display more accurate and richer colors compared to other phones. Most devices, including the iPhone 6 Plus, only offer around 100 percent color gamut. The company says it achieved that percentage by combining a blue LED chip with red and green phosphors instead of yellow like in other LCDs.
