At IFA 2019, Panasonic is showing off a 'MegaCon' prototype display that dramatically increases the contrast ratio of an LCD panel, delivering deep blacks and 1000 nits peak brightness for a 1,000,000:1 contrast ratio.
Codenamed 'MegaCon'The 'MegaCon' prototype was developed by Panasonic based on the company's own dual layer LCD technology, first announced in 2016 and already employed in some form in - very expensive - studio reference monitors. This one is much bigger at 55 inches.
Dual layer LCD technologyHow does it works? It is essentially two LCD panels sandwiched on top of each other. One is a monochrome inner panel that modulates luminance from the LED backlight while the outer is an IPS-based 4K LCD panel. - "It uses a high performance 4K outer panel with a monochrome inner panel to modulate the direct LED backlight, thus delivering pixel-level dimming and a contrast ratio of 1,000,000:1 which is unheard of for LCD panels," the company explained Examining the display from a shorter distance, it would appear that either the dual layer structure (monochrome panel with lower resolution than 4K?) or a pixel technique reduces effective resolution somewhat. It affected fine details in the picture but we had to get pretty close during the demo to spot it. The prototype is also thick and runs quite hot. It is of course a prototype so we are sure that Panasonic is tweaking it.
