LG Display today disclosed its latest QHD (Quad High Definition) LCD panel for smartphones - the one that will be used in the company's next flagship mobile device to be unveiled at the end of the month. The display accurate colors with a 120 percent color gamut, exceeding the 100 percent gamut offered on conventional panels (such as the iPhone 6 Plus) for mobile devices (based on sRGB).The QHD display has 1,440 x 2,560 resolution, four times higher than HD resolution (720 x 1,280), and the number of pixels per inch is 538 PPI (Pixels Per Inch) on the 5.5-inch panel size.

The new panel also adopted Advanced In-Cell Touch (AIT) technology which is said to offer excellent touch sensitivity so that it can respond to touch commands even with water drops on the screen. The display boasts advancements in other major image quality features, with a contrast ratio that is 50 percent higher than conventional QHD LCD panels, while the brightness has increased by 30 percent without any increase in power consumption.

The company received certification from Intertek, the provider of product safety testing and certification, for the superiority of the color gamut, brightness, and contrast ratio in the 5.5-inch QHD LCD panel.

LG Display employed three technologies to achieve the superior specifications of the new display: high color gamut LED, Advanced In-Cell Touch (AIT) and photo-alignment.

The high color gamut LED technology 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. LG Display has achieved a 20 percent improvement in color gamut with this technology.

Developed by LG Display, AIT represents an improvement over conventional 'In-Cell touch technology'. Instead of placing the touch panel on top of the LCD, the touch sensor is embedded within the LCD. This results in a slimmer design as the thickness of the panel is reduced by eliminating the need for an additional space for touch functions.

The photo-alignment technology uses UV light to form a liquid crystal alignment layer in the display panel, which helps achieve a higher contrast ratio by aligning the liquid crystals evenly to reduce light leakage.

LG plans to launch its new G4 smartphone on April 28th.
