LG Display said that 3:2 aspect ratio is popular with usersIn the next part of the suite, we looked at IT, mobile and automotive applications. Highlighted technologies were Advanced In-cell Touch (AIT) which allows a slimmer and narrow bezel set design and high performance (using passive pens and gloves) and better visibility in difficult lighting as there is better optimisation of the optical stack.
One of the key technologies for LG is UV alignment. We first reported on UV alignment techniques in May 1996, but LG is now moving this to mainstram products. The company told us at SID in June that the technique could be used to boost native contrast (without backlight modulation) from 1,200:1 to 1,800:1 in its IPS panels.
A new “N” type liquid crystal (LC) material is also being used to improve performance. The new material exhibits better homogeneity, improving black performance and transmissivity – the performance was visibly different in contrast and on the demos shown, there was about a 10% drop in power consumption for the same brightness. We noted that the viewing angle performance was very good – better than previous IPS materials.
LG showed us a new aspect ratio that it has been looking at. The firm has found from market research that users prefer 3:2 format (effectively 16:10.66) for many IT applications) and that it works better for many text-based applications. At the moment, LG is considering panels to make in that aspect ratio and is looking at 11″ (1440 x 960), 12″ and 13.1″ (both 1920 x 1280) for notebooks/hybrids and large tablets. The panels are available from Q2.
