Display

LG's True HD IPS Plus display has always been one of the preferred LCD panels around, and the good viewing angles and sharp colors found on the Optimus GJ are a testament to that. While a 720p display seems almost archaic in a modern-day market overflowing with 1080p flagships, the quality of the LCD panel found in the GJ is certainly towards the upper range when it comes to smartphones.

Images on the screen indeed look great and colors pop, especially the reds. For display purists, LG panels feature some of the most accurate color reproduction to be found on smart devices.

The True-HD IPS + display is impressive

We also compared the Optimus GJ to the regular Optimus G. The smaller phone has a screen of 318ppi and, while you can't quite see individual pixels, you can still notice jaggies on curves and diagonals.

The Optimus GJ's screen has higher brightness, though the contrast is somewhat worse. It has a noticeable advantage in viewing angles, the Optimus G screen starts showing a shift in contrast earlier and the effect is much stronger. The Optimus GJ screen is a bit more reflective though.

The capacitive sensor on the screen is very sensitive and will detect touches even if you're wearing gloves, using a long fingernail or an improvised stylus (like keys, some pens, etc.). Unfortunately, there was also a fair number of accidental taps as the screen is a bit too receptive.
