TCL CSOT shows off the world’s highest pixel density displays for XR | Infinium-tech

Display Week 2026 was held in Los Angeles last week – it was an opportunity for the world’s largest display manufacturers 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 C-Micro LED panel, with the highest pixel density in the world at 5,131 ppi.

Its resolution is 1,280 x 720px, which is not enough for VR, but enough for information overlays in AR glasses. If the verbose name above doesn’t make things completely clear, it’s a micro LED display built on a silicon substrate – all in one single chip.

Micro LED is similar to organic LED (OLED) in that each pixel emits its own light and does not require a backlight like LCD. The problem until now has been packing non-organic LEDs tightly enough to create pixel-dense displays.

For advanced XR devices, TCL CSOT introduced the world’s tallest Real RGB G-OLED display – it measures 2.24″ and has a density of 1,700ppi. It operates at a resolution of 2,600 x 2,784px. The display features a 120Hz refresh rate with microsecond response time, deep contrast, and low power usage.

The “G” in “G-OLED” stands for “glass,” which is the substrate used here — in other words, TCL built the OLED on top of a sheet of glass. “Real RGB” probably refers to full-stripe RGB rather than the usual OLED sub-pixel shenanigans.

The TCL CSOT also featured other similar displays, such as the world’s highest-res single-chip multi-color C-Micro LED display (0.28″), the world’s highest-res 1,512ppi XR display (3.59″) paired with a cockpit and even an LCD panel, the world’s tallest 2,200ppi LCD XR display (2.48″).
