11-06: SK Hynix will start the early stage of mass production of the “4D NAND” later in 2018; Samsung Galaxy S10 reportedly would adopt Qualcomm’s third-gen ultrasonic fingerprint sensors; etc.


AMD has launched an addition to the EPYC line. The EPYC 7261 has just 8 cores and 16 threads. But, unlike the existing EPYC 7251, the 7261 has all 64MB of its L3 cache enabled, as well as a significantly higher base clock, a TDP of 170W instead of 120W, and support for DDR4 2666. For reference, AMD’s 8 core Ryzen desktop CPUs only have 16MB of L3, and Intel’s new i9-9800X has 16.5MB.  (CN Beta, HardOCP)

Samsung Galaxy S10 is now rumoured to debut with an Exynos 9820 SoC that will include a dual-core NPU (neural processing unit) to offer an enhanced artificial intelligence (AI) experience. The new chipset is claimed to be based on 7nm process.  (Phone Arena, ET News, NDTV, Sam Mobile, Kejilie)

When volume production of micro LED can kick off remains unclear, but mini LED used as backlight source of LCD display has already entered mass production in the 2H18 thanks to its lower cost and easier application involved, according to Digitimes Research. (GSM Arena, Digitimes, press, Baijiahao)

Industry insiders indicate that the mini LED technology is mature enough, and even enters mass production in 2018, but has not yet reached massive production. Take a standard smartphone as an example—a 5” mobile phone display contains approximately 25 LED units, while a mini LED backlight can contain 9,000~10,000 units. This will result in a better HDR effect due to finer control. (CN Beta, HQEW, OfWeek, KK News)

LG Display (LGD) CEO Sang-Beom Han has revealed that the company will begin to mass produce OLED televisions at 8K resolution starting in May 2019 alongside plans to launch the products to market as early as Jun 2018. LGD also plans to begin producing and then commercializing an LCD-based version of the panels soon after to help drive the technology into the mainstream consumer market.

Samsung has filed a patent with in-display sensors to include antennas and a better integration of selfie-cameras. The patent describes a method for placing microphones, receivers, and sensors behind minuscule cutouts in the display panel itself, buried underneath the glass top layer.  (Phone Arena, LetsGoDigital, Android Headlines, Sina)


SK Hynix has launched what the company claims is the world’s first 96-layer 512Gb CTF (charge trap flash)-based 4D NAND flash based on its TLC (triple-level cell) arrays, using 3D CTF design paired with the PUC (peri. under cell) technology. The company will start the early stage of mass production of the chips later in 2018. SK Hynix has combined its 3D CTF with PUC, which is different from the way of integrating 3D floating gate and PUC. Therefore, the company named the product “CTF-based 4D NAND flash” to distinguish it from current 3D NAND flash technologies. (CN Beta, Digitimes, press, Clean Room Technology)


Samsung Galaxy S10 reportedly would adopt Qualcomm’s third-gen ultrasonic fingerprint sensors. Ultrasonic fingerprint sensor modules can capture a 3D image of fingerprints, including the sweat pores and ridges. It can also cover 30% of the surface. (GSM Arena, Twitter, 91Mobiles, Huanqiu)

Texas State and Duke Universities in the US have shown how 3D printing and nanotubes can be used to lessen restrictions on shape and size. They have used 3D printing a prototype LED bracelet and self-darkening LCD sunglasses, each with a built-in lithium-ion power cell. The ability to 3D print lithium-ion batteries in an arbitrary geometry would not only allow the battery form factor to be customized to fit a given product design, but also facilitate the use of the battery as a structural component.
