TCL CSOT is showcasing its latest advancements in display technology at Display Week 2024, including the world's first 1000Hz LCD and a 14-inch QD-EL, also known as NanoLED.
CSOT is TCL's display manufacturing arm in China and a rising competitor to South Korea's LG Display and Samsung Display. TCL CSOT's display panels are today used in TVs from TCL, Samsung, Sony, and Panasonic, among others.
At the annual industry show Display Week, TCL CSOT is presenting its latest advancements in display technology as well as display prototypes. At least some of these panels are expected to appear in consumer products in the coming years.
TCL's first QD-EL display
The original name, QLED, was misused, so the electroluminescent quantum dots display technology, where electricity is applied directly to the quantum dots, goes by many names: NanoLED, QDEL, QD-EL and QD-LED.
TCL is showcasing the first 14-inch inkjet-printed QD-EL display. It features a 2.8K resolution, 30-120Hz refresh rates, and 85% BT.2020 coverage. The company says that inkjet printing can significantly reduce production costs.

Some in the industry see this technology as the next step after OLED, but challenges remain on the path to commercialization, including the limited lifetime of the blue QLED. TCL did not provide an update on the lifetime.
World's first 1000Hz LCD
At Display Week 2024, TCL is also showcasing the world's first 1000Hz 4K LCD monitor panel. The fastest monitors on the market today are 480Hz OLED and 540Hz LCD, both at 1080p resolution.

TCL says that 1000Hz "heralds a new era in gaming". Displays today still exhibit motion blur at very high refresh rates due to the sample-and-hold principle, so 1000Hz is warranted – not just a spec race – according to Blur Busters.
However, to benefit from this technology, we also ideally need 1000fps content and a new cable interface standard that goes beyond HDMI 2.1 and DisplayPort 2.1 bandwidth.
16" 8K LCD and WHVA
Also on display from TCL is the highest-resolution laptop panel, measuring 16 inches with 8K resolution for a pixel density of 550ppi. It is an LCD panel with sRGB colors, so it is not ideal for working with graphics, but it is nevertheless a noteworthy development.

In addition, TCL CSOT is showcasing its wide-angle HVA (WHVA), an evolution of the classic VA LCD panel. FlatpanelsHD first reported on the WHVA technology at CES 2024 in January in our article 'Did TCL just solve LCD's viewing angle problem?'. This technology may appear in TVs in 2025.
