LG is boosting excitement ahead of its LG G4 unveiling later this month, introducing the upcoming flagship's 5.5-inch QHD IPS LCD display.

LG Display not only announced the launch of this new QHD LCD panel for smartphones, but it also confirmed that it will grace its next-generation LG G4 flagship smartphone, set to make its official debut on April 28.

"LG Display, the world's leading innovator of display technologies, announced today that it has launched a QHD (Quad High Definition) LCD panel for smartphones that represents a quantum jump in terms of key features, including color gamut, brightness, contrast ratio, touch function, power consumption and thinness. The company has started the mass production of the 5.5-inch QHD LCD panel with IPS technology for mobile devices that will be used in LG Electronics' forthcoming flagship smartphone to be unveiled at the end of the month," LG revealed in a new press release on Friday, April 3.

The company's latest high-end display boasts a number of neat innovations such as a higher color gamut and Advanced In-Cell Touch (AIT) technology, which offers "excellent touch sensitivity."

LG further explains that it focused on three key areas with its new display panel. First of all, the display boasts an improved color gamut that's 20 percent better compared to existing LCD panels. In order to accomplish this, LG combined a blue LED chip with red and green phosphors rather than yellow phosphors as with existing LCD displays.

The new display also has a contrast ratio that's 50 percent higher than conventional QHD LCD panels, LG further touts. The brightness has reportedly increased by 30 percent, without affecting power consumption. Due to these advancements, the display will be comfortable to use even under bright light.

AIT technology, meanwhile, means that LG embedded the touch sensor inside the LCD itself, rather than overlaid on top of the display panel as with regular touch displays. This allows for a slimmer overall panel by reducing the layers, while also making the display more sensitive to touch. According to LG, the display will respond even to water drops. This could be a hint that the upcoming LG G4 may boast a slimmer profile and come with water-resistant capabilities.

Lastly, the display measures 5.5 inches, has a resolution of 2560 x 1440 pixels, and a pixel density of 538 pixels per inch (ppi).
