Samsung Display expects to use vertical deposition to make OLED panels on Gen 8.5 substrates

Published

According to the source, Samsung Display will try to move to vertical organic material deposition in the production of OLED panels for tablets, laptops and monitors using Gen 8.5 substrates. The South Korean display manufacturer allegedly partnered with the Japanese company ULVAC to develop the equipment needed for this process.

Gen 8.5 (2200 x 2500mm) substrates are more cost effective for tablet, laptop and monitor panels than Gen 6 (1500 x 1850mm) substrates currently used to make OLED panels for smartphones. A single Gen 6 backing produces 48 13.3-inch panels, while a Gen 8.5 backing produces 96 such panels.

The vertical deposition method consists in the fact that the glass substrate is vertical and the organic material from the gas phase is deposited on it from the side. For Gen 6 substrates, the horizontal deposition method is mainly used, where the substrate is placed horizontally and organic material is deposited on it from below. Samsung Display wants to move to the vertical method as it minimizes the sag of the mask used during deposition.

Thin metal masks used in deposition in the horizontal method inevitably sag in the center over time due to gravity. If you position the matte and mask vertically, there will be no sagging.

However, vertical spray equipment is not yet used in mass production. One reason is that vertical deposition requires higher temperatures, which can change the characteristics of the organic material. In 2017, Applied Materials supplied Japan’s JDI with several kits that were used to make OLED panels for the Apple Watch. However, their productivity was only 2,000 Gen 6 substrates per month.

The Gen 8.5 substrate handling equipment for Samsung Display is likely to be developed by Japanese company Canon Tokki, which is currently the exclusive supplier of Gen 6 vertical deposition equipment for Samsung Display.

Windows 11 introduces third party widgets

Microsoft has released a new test build of the Windows 11 operating system in the Developer (Dev) channel.

Windows 11 introduces third-party widgets

The assembly is available to members of the Windows Insiders program. The main new feature in build 25217 is the long-awaited support for third-party widgets.

Windows Insiders can now start developing and testing widgets for their apps. Widgets can be added to the widget board, which is currently only populated with web content offered by Microsoft.

Because this is a preview, developers are not yet able to submit widget-enabled apps to the Microsoft Store. Accordingly, users cannot simply find applications with widgets right now.

This is the worlds lightest 16 inch laptop It is equipped

Acer has launched the world’s lightest 16-inch laptop. Acer Swift Edge was shown a couple of months ago, but now it has become known that the novelty has appeared on sale at a price of $ 1,500.

Acer Swift Edge really impresses with its weight. With a 16-inch screen, the laptop weighs only 1.1 kg! This is not much even for 13-inch models, let alone 16-inch models.

To achieve such a mass, Acer came out, including through the use of an aluminum-magnesium alloy and not the largest battery. It here has a capacity of 54 Wh, which is quite small for a 16-inch model. But this supposedly should be enough for 10 hours of work, according to Acer itself.

But low weight is not all that a laptop can please. First, it also has a 4K UHD OLED screen. Secondly, the Ryzen 6000U processors serve as the heart, which are not only very productive, but also offer very powerful iGPUs.

From the rest, you can note RAM up to 32 GB, SSD up to 1 TB, a pair of USB-C 3.2 Gen2 ports with support for DisplayPort and USB Power Delivery, HDMI 2.1, two USB 3.2 connectors, Wi-Fi 6E and Bluetooth 5.2.

For those same $ 1,500, a far from the most basic version with a Ryzen 7 6800U, 16 GB of RAM and a 1 TB SSD is already available. That is, modifications with the Ryzen 5 6600U will be even cheaper, but there are no prices yet.

Yes the Ryzen 7000 gets very hot but the Ryzen

The Ryzen 7000 processors proved to be very productive, but also quite hot. Power consumption and temperatures have grown to about the level of Intel Alder Lake, and this affects the choice of cooling system. Can a regular AMD box cooler even handle a six-core Ryzen 5 7600X?

Despite the fact that this CPU has only six cores and power consumption in the range of 90 W, in many tests, even with liquid cooling, it heated up to 90 degrees and above. However, it turned out that everything is not so simple.

Our colleagues at TechSpot decided to try out the Wraith Spire cooler and were surprised by the results.

So, if you do not perform any manipulations with the CPU, then, for example, in Cinebench R23, a processor with a boxed cooler scores 5% less points than with a GSO due to a 3% drop in frequency. At the same time, the temperature rises from 93 to 101 degrees, that is, not so much, given the difference in performance between the coolers.

Also for the Ryzen 7000, you can activate Eco Mode, which reduces the power limit to 65 watts. This allows you to reduce the temperature by 7-16 degrees, depending on the cooler, and the performance drops by literally 1.5-4%. It is also possible to activate the PBO2 mode with reduced voltage, which results in a less significant decrease in temperature, but performance is even improved, albeit only by 2%. As for power consumption, it drops by 24% in Eco Mode.

In games, the situation is different. They do not load the processor so much, therefore, the power consumption in most cases is very modest (about 60-80 W), and temperatures rarely reach even 60 degrees, that is, they are in a completely normal range.

As a result, we can state that even a cooler of the Wraith Spire level is enough for stable operation of the Ryzen 5 7600X with an almost imperceptible decrease in performance and a not very significant increase in temperature. However, this raises questions about the temperature regime of the Ryzen 7000 as a whole, because the difference (in CPU heating) between a fairly simple air cooler and liquid CO turns out to be insignificant, and this is strange. Exactly what architectural features or settings of the Ryzen 7000 lead to operation at such high temperatures, even with LSO, is not yet clear. Especially when you consider the rather modest power consumption, because it turns out that the Ryzen 5 7600X heats up to 100 degrees, consuming only about 90 watts.

But it is also worth understanding that such a situation will only occur in a number of applications that can fully load all the CPU cores, while in the same games both temperature and power consumption do not raise questions.

If you still want to lower the processor temperature, you can activate Eco Mode, which has almost no effect on performance.

Separately, it is worth recalling the words of AMD itself regarding the temperature regime of the Ryzen 7000. The company did not go into details regarding the reasons, only mentioning the 5 nm process technology, but assured that 95 degrees for new CPUs are the norm. The processor will strive to increase the frequencies as much as possible, remaining within the same 95 degrees, regardless of the CO used. At the same time, this temperature is not dangerous for the CPU, and only at 105 degrees the throttling process is activated.
