By all accounts, the 15.4-inch touch screen of a Tesla Model 3 is large. So too are the up to five touch screens you can fit to the Porsche Taycan. But Cadillac must think these efforts are a little half-hearted.

That's why the first teaser it has published of the 2021 Escalade SUV features its enormous 38-inch dashboard display. Details are scarce for now, but Cadillac claims this is the first curved OLED display in the industry.

The automaker also says the display has twice the pixel density of a 4K television. Given a 4K television 38 inches wide would have a pixel density of 116 per inch, this means the Cadillac display has a density in the region of 230 per inch.

This is still some way short of smartphones, which are generally in the 300 to 400 pixels per inch region, but it is impressive for a car display, which is generally much further away from your eyes than a phone, so pixel density matters less.

We can also compare the Cadillac's display to one which is even bigger, and also due to enter production in 2020 - that of the Byton M-byte electric SUV. That display is even bigger, at 48 inches, but is flat and rectangular, not curved like in the Escalade.

The Byton's has a resolution of 3840 x 720, which means a pixel density of just 81.4 per inch. This math suggests the Cadillac's infotainment display will be considerably sharper than the Byton's, and its use of OLED technology instead of LCD means its blacks will be deeper and its colors richer.

There isn't much else to say about the new car's interior, but we can at least see a pair of steering wheel stalks, suggesting Cadillac hasn't taken Tesla's approach of putting even the wiper controls on the touch screen.

On a similar note, we can just about make out a series of buttons below the display, again suggesting that some key controls are physical, making them easier to touch using muscle memory, instead of tapping at the display with an outstretched finger.

Cadillac says it will show off more of the new Escalade in February, and sales will begin in late 2020.
