WG Tech (World Glass Technology) showcases its use of glass substrates for mini-LED backlights and micro-LED applications, presenting an alternative to traditional PCB-based designs. The company's core process involves buying raw glass and applying circuitry using sputtering and photolithography, a method borrowed from semiconductor manufacturing. This technique enables finer pitch and higher precision compared to conventional PCB processes, allowing for denser mini-LED arrays.

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

A key demonstration is an 85-inch TV with an RGB mini-LED backlight featuring 16,128 dimming zones. Because the substrate is transparent glass, the backlight can project synchronized ambient light from the rear of the display, creating an immersive effect. This design feature is also shown on a 32-inch mini-LED monitor, which achieves a thickness of only 6.5mm, including a touch sensor. The glass substrate eliminates the need for a traditional metal backplate, reducing cost and thickness.
WG Tech's other primary technology is Through-Glass Via (TGV), which creates metallized connections through the glass substrate. This is critical for their micro-LED and semiconductor packaging applications. The company displays examples of TGV for a Google sensor, where glass replaces a PCB, and for Micro-LED in Package (MIP) modules. The same photolithography process is also used to create antennas directly on the glass.
The company, based in China, has been developing these glass processing technologies since 2019 and began mass production in late 2023, with products entering the international market in Q2 2024. They position their mini-LED on glass technology as a cost-effective alternative to OLED, offering comparable optical performance with benefits like the integrated ambient lighting.
While the large 85-inch display uses RGB mini-LEDs for a wider color gamut, other demonstrated products use blue mini-LEDs with color filters. The company sees glass substrates as the future for high-performance mini-LED backlights, enabling thinner, more precise, and feature-rich display designs.
