AUO Optronics 2018 Panel Production Roadmap Revealed

AUO Optronics

TFT Central reported AUO Optronic’s panel production plans for 2018. The post is lengthy, but the highlights include:

  • Production for the 27″ 144Hz 3840×2160 true HDR IPS panels featured in the Asus ROG Swift PG27UQ, Acer Predator X27, and AOC AGON AG273UG are delayed to November 2017, with release expected Q1 2018.
  • 32″ versions of the above panels are expected to be produced Q3 2018 for a Q4 2018 release.
  • 27″ 240Hz 2560×1440 TN panels with 90-95% DCI-P3 coverage and 600 nits peak brightness (for HDR “support”) are planned for Q2 2018 production, with the curved 25″ 240Hz 1920×1080 TN versions to follow Q3 2018.
  • AUO plans to decrease the native average GtG response times on their TN panels from 5ms to 3ms, and their AHVA (IPS-type) panels from 14ms to 10ms before overdrive is applied.
  • 35″ 120Hz 3440×1440 VA ultrawide panels with 90% DCI-P3 coverage and 600 nits peak brightness (for HDR “support”) are planned for January 2018 production, with the 200Hz VA versions that include 1000 nits peak brightness being pushed back to Q2 2018 production.

Hmm when people get those 27s with 40% less motion blur, more brightness, greater pixel density, wider color gamut, and of course 2.5 more inches of monitor they are really gonna have an edge on me.

Regarding the “40% less motion blur” — that assumption needs to be very carefully & scientifically clarified.

Motion blur is more tied to MPRT (pixel visibility time) rather than GtG (pixel transition time).

The decrease from 5ms to 3ms before overdrive will be very good for reducing strobe crosstalk and allowing better 480Hz abilities (in the future). However, you can still reduce motion blur by nearly a full 50% simply by doubling refresh rate (120fps@120Hz -> 240fps@240Hz) on a sample-and-hold display, as long as most of the overdriven GtG is fully complete in a tiny fraction of a refresh cycle.

On an ordinary 1ms GtG TN panel (GtG10%->GtG90% measurement spec, via overdrive), MPRT during sample-and-hold operation is roughly (refresh cycle + majority of GtG). The GtG curve is not squarewave and muddies the exactness of this. However, in this case, 60Hz vs 120Hz vs 240Hz can be comparing MPRT ~17ms versus 9ms versus 5ms (basically motion blur size ratios of 17:9:5 for the 60:120:240 situations running at full framerate matching refresh rate) even if GtG is unchanged at 1ms for the 10->90% trigger points. GtG is not an easy number to interpret.

The photons of GtG is visible to the human eye well before the full completion of GtG, and the shape of the GtG curve dictates the smearing/coronas/ghosting above-and-beyond the sample-and-hold effect which dictates a guaranteed minimum MPRT of one full refresh cycle (e.g. 60Hz = guaranteed MPRT of minimum 16.7ms during non-strobed non-PWM operation). That said, GtG 10%->90% is extremely representative of average amount of extra motion blurring above-and-beyond sample-and-hold effect, so in this particular case, 1ms is more accurate (for a human-notices-the-photons sense) than the 3ms-5ms (which more dictates the annoying smearing/coronas/ghosting effects). With good neutral overdrive (not too much, not too little), GtG has successfully ceased to be a significant influence on MPRTs (at least on TN panels in the 60Hz to 144Hz leagues). It begins to re-emerge as a slight blurring factor, as you’re only getting a roughly 5:9 ratio of motion blur rather than a full halving of motion blur when going from 120Hz->240Hz, due to GtG.

As long as most of the visual GtG progress is complete in a tiny fraction of a refresh cycle (roughly 80% of GtG progress, from the 10%-90% triggerpoints) then it is possible to get nearly 50% less motion blur (without strobing) by doubling refresh rate and frame rate without even changing GtG speed; as long as overdrive is carefully properly calibrated for that specific refresh rate (to prevent the undershoot/overshoot artifacts of coronas/ghosting/etc). As MPRT is frame visibility time, double frame rate (and double refresh rate), effectively halves the MPRT (motion blur seen by human eye).

That said, MPRT (instead of GtG) is a much more mathematically accurate prediction of the amount of motion blur to expect from a non-strobed LCD. The devil is in the details of how GtG affects MPRT, given all the technical details explained above.
