TCL CSOT shows off the world's highest pixel density displays for XR

Display Week 2026 was held in Los Angeles last week – it was an opportunity for the world’s largest display makers to showcase their most advanced technologies. TCL CSOT’s presentation focused on eXtended Reality (XR) applications.

The first is a tiny 0.28” display – small enough to be embedded in lightweight smart glasses. However, this tiny display is a single-chip full-color Si-Micro LED panel with the highest pixel density in the world of 5,131ppi.

It has a resolution of 1,280 x 720px, which isn’t enough for VR, but is plenty for an information overlay in AR glasses. In case the wordy name above didn’t fully explain things, this is a Micro LED display that is built on a silicon substrate – it’s all one single chip.

Micro LED is similar to Organic LED (OLED) in that each pixel emits its own light and doesn’t need a backlight like LCD. The problem so far has been packing non-organic LEDs tightly enough to make a pixel-dense display.

For advanced XR devices, TCL CSOT presented the world’s highest Real RGB G-OLED display – this one measures 2.24” and has 1,700ppi density. That works out to a resolution of 2,600 x 2,784px. This display has a 120Hz refresh rate with microsecond response times, deep contrast and low power usage.

The “G” in “G-OLED” stands for “glass”, which is the substrate used here – in other words, TCL created OLEDs on top of a sheet of glass. The “Real RGB” presumably refers to a full-stripe RGB instead of the usual OLED sub-pixel shenanigans.

TCL CSOT also showcased other similar displays like the World's Highest-Res Single-Chip Multi-Color Si-Micro LED Display (0.28"), World's Highest MP 1,512ppi XR Display Paired With Cockpit (3.59") and even an LCD panel, the World's Highest 2,200ppi LCD XR Display (2.48").
