USI-T 2.0 Intra Panel Interface Applied
Simplifying TV circuits with 4Gbps transmission speed
Strengths in slim and bezel-less design

The popularization of 8K TVs is gradually approaching.

On the 29th, Samsung Electronics unveiled the 'S6CT93P', a Display Driver IC (DDI) featuring a USI-T (Unified Standard Interface for TV) 2.0 intra-panel interface optimized for large 8K ultra-high resolution displays.
Global TV companies are leading the TV market by successively introducing ultra-high-resolution products featuring large display panels of 65 inches or larger that support 8K.

To implement 8K (7680 x 4320, 33 million pixels), technology is required to rapidly transmit high-capacity data, with the number of pixels increased 16 times compared to Full HD (1920 x 1080, 2 million pixels), to each pixel of the display panel in real time.

The S6CT93P DDI product incorporates USI-T 2.0, developed in-house by Samsung Electronics, enabling image signal transmission at a fast speed of 4Gbps per second.

With transmission speeds doubled compared to the existing USI-T 1.0, images and videos can be viewed seamlessly even at ultra-high resolution of 8K.This can be implemented.

By using this product with a high-speed interface, TV manufacturers can reduce internal data transmission lines, enabling the realization of thinner bezel-less TV designs.

In addition, Samsung Electronics applied the 'Smart Equalizer' function to the S6CT93P product to make panel development much easier.

Existing display panel developers had to go through the step of directly inspecting the equalizer circuits of each DDI to find the optimal conditions in order to minimize distortion caused by image data loss during the high-speed transfer from the Timing Controller (TCON) to the DDI.

The Smart Equalizer enables bidirectional communication between the T-Con and each DDI, allowing each DDI to automatically produce optimal picture quality when the T-Con is adjusted. This prevents developer errors, reduces the malfunction rate, and shortens the TV development period.

“To support large TVs with 8K resolution beyond 4K, high-speed signal transmission at 4Gbps is efficient,” said Heo Kuk, Executive Vice President of the Marketing Team at Samsung Electronics’ System LSI Business Division. “We expect that the S6CT93P, which supports the new high-speed interface of USI-T 2.0, will enable us to maximize the user experience for 8K TV viewers.”
