TCL CSOT’s Focus on MicroLEDs at DisplayWeek 2024

TCL CSOT showed a microLED video wall, along with several microLED and LCD displays aimed at the automotive market

Hi everyone, Chris Chinnock here for Insight Media. It’s DisplayWeek 2024 and I’m in the TCL CSOT the China Star booth where they’re showing off a number of microLED devices. So, let’s start with the big display out here on the outside of their booth. This is 163 in microLED display. This was shown at CES earlier this year. I think it was also at IFA last year. It is very nice-looking display and it does use microLEDs but these are on PCB backplanes so that’s really more of a traditional digital signage or video wall type of architecture. They have a little bit smaller LEDs compared to what you would normally use in a video wall. It looks nice but I would call this kind of an intermediate kind of a product.

Moving inside, they have a series of automotive products. This is their automotive AR HUD application, which I believe was also shown at CES. You can see it’s a standard LCD panel at this point so there’s nothing really spectacular about this. It’s a 5.1 in LCD with resolution of 1440 by 480, a field of view of 15.5 by 3.5 degrees. Perhaps a little bit more interesting is that they do have a microLED version of that panel at 5.1 inch in development. They say they’ll use microLEDs that are in the range of 30 to 50 microns and it will maintain this same field of view and resolution and size to fit into the architecture here as well. It’s going to be LTPS on glass.

This is what they call a rear seat entertainment display. Tianma had something very similar to this and the architecture is shown here. It’s actually very simple. The display in this case is mounted below the headrest. There is a half mirror and reflector so what you see is a virtual magnified image at an apparent distance of about 6 meters. It’s actually a very comfortable display. It almost looks like what we call a collimated display in the simulation world. I actually like this one quite a bit.

Moving along to their pillar-to-pillar display, now we’re into LCDs. As you can see, this goes pillar to pillar. I believe it’s mini-LED backlight with some of the specifications you can see here its LCD.

Coming back now to microLED, this is a B pillar display, so something placed in the pillar between the front seat and the rear seat, just to mostly give a little bit of information or a little bit of ambiance. It’s a different concept. I haven’t seen a B pillar display yet, so this is kind of cool

Finally, this is what they call an automotive floating image. It might be a little hard to capture with the camera, but this is a floating image. My finger is kind of in the image at this point, again, a little hard to capture. Architecturally it’s quite simple. Looking down the barrel here if you look inside here there is a sheet. I guess it’s a little hard to see but there’s a sheet inside there which has a series of micro lenses. And those micro lenses have a one-to-one correspondence with a 500x 500-micron microLED panel that sits behind it. It works pretty actually works very well. I mean it’s a flat image so it’s not a light field display the way everyone claims. It is a floating flat image but it’s not bad especially if you could add some touch capability to this. It might be let’s call this a kind of a virtual avatar for in your car or some other application like a kiosk for example. Pretty good. I think that’s most of the story here at CSOT. It’s Chris Chinnock.
