With the continued evolution of high-definition televisions, the worlds displayed on our TV screens have gotten extra life like than ever. 8K TVs, which signify the brand new normal of premium tv, maximize immersion by offering such vivid excessive definition that it’s like customers are beholding the scenes earlier than their very eyes.
This extremely sharp decision was made potential by the enhancement of the semiconductors inside the TVs. Capable of enabling the features that enable sharper decision, these options are the DTV SoC (Digital TV System on Chip), T-CON (Timing Controller), and DDI (Display Driver IC). Samsung Newsroom sat down with the builders of S6HD820 (which opened the door for 8nm1 DTV SoC), S6TST21 (the trade’s first 8K 120Hz T-CON) and S6CT9BC (a DDI with a most pace of 8Gbps) to listen to the story of the unseen innovation behind these options.
From DTV SoC to DDI – Sending Video Signals to Displays
Unlike prior to now when televisions had been solely used for watching exhibits, the position of the TV has steadily expanded over time. These days, our TVs have gotten a platform that additionally permits us to play video games, work out in addition to do a broad vary of different actions. As individuals come to count on a extra various vary of options from their TVs, a better normal of premium options can also be being dropped at televisions.
TVs are output units for content material, making a excessive normal of image high quality essential for person satisfaction. Digital indicators typically bear three phases earlier than being displayed. First, the DTV SoC receives compressed knowledge from broadcasts or the web, extracts the info to transform it into video and sends the video and audio to the display and audio system. The T-CON then receives the processed video knowledge and sends it again to the DDI with cautious timing to make sure easy operation. Last, the digital sign despatched to the DDI is transformed to an analog format and the video is displayed on the TV display.
Simplifying DTV SoC with ‘One Chip’ and Enhancing NPU Function
The DTV SoC, which receives video knowledge from a cable or set-top field, can also be known as ‘the brain of the TV.’ Hansoo Seong, who’s a part of the DTV SoC growth group, explains that, “The DTV SoC extracts the audio and video signals separately from the compressed input stream. It then provides the function that adjusts the audio and video data according to each scene being displayed.”
As image high quality has advanced from the 4K to the 8K normal, the position of the DTV SOC has turn out to be extra essential. Samsung’s builders had been dedicated to discovering an answer that will help 8K decision whereas additionally lowering energy utilization on the similar time. An NPU (Neural Processing Unit) was utilized to the DTV SoC in order that AI know-how may very well be utilized to the general enchancment of each image high quality and audio processing. This know-how led to a way more exact show output. On high of this, the DTV SoC has been built-in with an upscaling IC2 to enhance energy effectivity.
The largest hurdle in creating the 8nm1 DTV SoC, referred to as S6HD820, was the advanced engineering required to combine two ICs into one chip and the next difficulty of overheating. “The better the NPU performance, the more the AI learning is reinforced, which leads to better TV performance. But this also makes semiconductors that much more complex to engineer and results in more severe overheating,” mentioned Hansoo Seong. “We worked hard to find the right balance to prevent excessive overheating, and eventually succeeded in optimizing the solution.”
The Evolution of T-CON: From Two 60Hz Chips to a Single 120Hz Chip
The T-CON takes the video knowledge from the DTV SoC and converts it in response to the calls for of the DDI. “The…
