The LG Q60, LG K50 and LG K4.

LG Electronics took the wraps off three new midrange phones Tuesday, less than a week before the world's biggest phone show kicks off.

The LG Q60, K50 and K40 feature high-end displays and a focus on artificial intelligence. All three will feature LG's HD+ FullVision display, the 6.26-inch version for the Q60 and K50 and the 5.7-inch version for the K40. All three will also have an AI feature called AI CAM, which helps the camera recognize the object that's in front of it -- humans, pets and food, for example -- and adjust its settings accordingly.

All three also have a dedicated Google Assistant button and sport DTS:X 3D Surround Sound, a high-end audio technology that simulates a 7.1-channel surround sound system. The Q60 and K50 are powered by a 3,500-mAh battery, while the smaller K40 is outfitted with a 3,000-mAh battery.

The big differentiator among the phones is the camera setups. The Q60 and K50 both feature 13MP front-facing cameras, but the Q60 has three cameras on the back. There's a 16MP camera with Phase Detection Auto Focus (PDAF), a 5MP for Super Wide Angle, and a 2MP shooter with Depth Sensor.

The K50 pares back its rear-camera setup a bit with a 13MP with PDAF and the 2MP shooter with Depth Sensor, while the K40 offers an 8MP front-facing camera and the rear-facing 13MP camera with PDAF.

All three also have a fingerprint sensor and support 2G, 3G and LTE networks. LG didn't reveal launch dates or prices but did say they would be on display at the Mobile World Congress, kicking off Feb. 25 in Barcelona.
