Tianma’s microLED and OLED Smart Cockpit Displays

Automotive displays were in abundance at DisplayWeek 2024 and Tianma had a wide variety on display. In the first video report below, we looked at their “Smart Cockpit” display solutions. This included a very nice rear seat entertainment display that almost looks collimated, a transparent microLED display to replace the side-view mirror, a bending OLED display featuring Corning’s Living Hinge glass, a slidable OLED and another transparent microLED.

Hi, Chris Chinnock here at DisplayWeek 2024. I’m in the Tianma booth and we’re going to take a look at their smart cockpit showings. So, let’s take a look. First of all, they’ve got a number of displays so let’s start in back of the cockpit here. So, this may be a little bit hard to see but this is a rear seat entertainment display and if you look closely there’s actually a little display kind of embedded up high. Then, there’s a half mirror with some magnification. It just basically projects this flat plane further out. It looks like maybe two or three feet in front of me instead of, well, instead of being two feet in front of me where this headrest is it feels like it’s more like four or 5 ft away. So that’s a nice feature to have in the back seat of the car. Very simple to implement.

If we move into the cockpit, these are all of the displays that we’re going to take a look at here, and I’ll put these specs a little bit later in the video. I just want to show you some displays as we go through them. So here is the transparent 8 in octagon microLED display. As you can see, it’s transparent. The idea is this is going to replace the side mirror on the car. Now we questioned why it needs to be transparent. The reason is an artifact of this demo. In reality, this would sit between the A pillar on the side of the car and above the dashboard so you would be able to see out onto the road and then still have this side view mirror application. The resolution looks fine, but the luminance looks a little low to me. This is supposed to be 500 nits, but again, maybe a little bit low in my opinion.  I believe all these microLEDs are on LTPS backplanes so it’s active-matrix drive with 55% transparency.

This one over here in their cockpit, they have two right here that are OLED displays.  They feature Corning’s living hinge glass. It’s a special thin glass that obviously is meant to move but there’s mechanical structure behind this thing that allows it to actually fold into the cockpit. So, if I press the button here for the demo you can see this thing starts to roll back into the cockpit. The idea is having this kind of nice rounded cockpit if you want just for ambiance purposes. And if you want to bring it back up when you’re driving this can come up to a straight position maybe a little bit more forward depending on where you want it.

Over here is what they call a stretchable display or I’m sorry a slidable display. It’s 13 in and it’s supposed to just slide right into the dashboard. Now it’s not working I guess as it apparently broke a little bit. But that’s the idea. Again, these are all really concepts to show to the tier one and the automakers to see what they what and might like to integrate.

Down below here is another microLED display. This is a 9.38 in one with a little bit lower luminance of 800 nits again, active matrix on LTPS, but this is a 70% transparency. You might be able to see my hand through this thing a little bit.

Those are the main displays that are part of their smart cockpit displays solution. Chris Chinnock for Insight Media.
