How Apple Brings HDR to Non-HDR Displays

Andrew Orr ·

Stu Maschwitz wrote an interesting article on Extended Dynamic Range, or how Apple brings High Dynamic Range to non-HDR displays. This doesn’t just refer to its Pro Display XDR; it’s how iPhone OLED displays can be defined as HDR.

So Apple has a method of showing HDR and SDR content together on the same screen. It works on every display Apple bills as “HDR,” even though the phones are performing the stunt using a different underlying technology than the 30″ Mac display. The XDR uses “local dimming” to light up an array of LEDs brighter behind the HDR pixels, as needed. The OLED displays drive each pixel to the desired brightness individually.

2020 Apple Watch Models Could get microLED Screens

Andrew Orr ·

New rumors suggest that 2020 Apple Watch models could get microLED screens, moving away from its current OLED display.

Switching from OLED to microLED is expected to bring miniaturization and battery life longevity improvements, as microLED pixels are more power-efficient. microLED panels are also less susceptible to burn-in artifacts compared to OLED.

LG's CES 2019 Curved OLED Screen Booth Display [Video]

Dave Hamilton ·

Every year at CES one of my favorite things is to visit the Central Hall to see all the new TV technology. This year LG again won my vote for most impressive display (no pun intended!) with its array of curved OLED screens. Showing a rotating series of nature videos, this array of curved displays was both immersive and astounding. The video doesn’t do it justice, of course, but it’s worth a quick look just to get an idea of what the future looks like. Enjoy!

CES – LG Booth OLED TV Video Tour

Dave Hamilton ·

LAS VEGAS – Every year at CES I make it a point to pass through the Las Vegas Convention Center’s Central Hall at least once just to see the spectacle of new TVs on display. Each year, all the big manufacturers try to out-do one another (including renting booth space under dummy company names and expanding last-minute) just to create the most impressive display. This year, for me, LG’s OLED TV tunnel was a perfect entrance to the mayhem. Thankfully, I got there before the power went out, but that’s another story for another time. For now, just enjoy my tour through the LG tunnel.
