Ahead of its Hong Kong launch later this month, LG has renamed the LG Optimus to the LG Optimus True HD LTE. That's along with the Spectrum and and Nitro HD names for the Verizon and AT&T versions, and LG Optimus LTE in South Korea and Japan. Why?

The "True HD" part doesn't mean the phone has a 1080p resolution on the 4.5-inch screen. Instead, Engadget reported the term is a knock on Samsung's screens used in devices such as the Samsung Galaxy Nexus, as the company doesn't believe the Galaxy Nexus's screen is high definition.

The screens on devices such as the Galaxy Nexus are PenTile 1280x720 screens, which LG claimed are not HD because of the lower number of sub-pixels. The company also criticised the AMOLED screen's higher power consumption in a "normal user environment." The company showed off its AH-IPS display, which has more consistent power consumption across different levels of overall whiteness, and uses the RGB structure which results in enhanced sharpness and image clarity. The company called this "Real HD" in its presentation.

The Optimus LTE has a 4.5-inch display with a 1280x720 pixel resolution at 329 pixels per inch - that's higher than the iPhone 4 and the iPhone 4S. The phone also features a 1.5GHz dual-core Qualcomm Scorpion processor with Adreno 220 graphics, 1GB of RAM and 4GB of internal storage, along with an 8-megapixel camera that supports 1080p. The phone features Bluetooth 3.0, 4G LTE, 3.5G HSDPA and runs Google 2.3.5 Gingerbread.

In terms of LG's competition, it would be surprising if Samsung didn't launch the Galaxy S3 with Ice Cream Sandwich even with Touchwiz on top. Leaked photos have recently shown a five-row device, which was claimed to be the S3, that runs Android 4.0 and the TouchWiz UI. The person who leaked the photo, said the device will have a 720p display and a physical home button, like the iPhone, which was apparently due to a last-minute change to the screen size. The five-row UI would not be unexpected, as the Samsung Galaxy Note does that already.

It remains to be seen whether Samsung's next Galaxy S device will up the screen resolution and clarity.
