Study reveals 3D printer that prints flexible OLED panels

Published

Televisions and monitors with OLED technology offer rich colors and high quality, but the price is a little high compared to other technologies. However, researchers at the University of Minnesota are developing a 3d printer home that can print the OLED circuits with low cost.

According to a study published in the journal Science Advances last Friday (7), researchers are using a 3D printer that fits on a regular table and costs the price of a Tesla Model S — the electric vehicle sells for US$ 89,900 (about R$ 508). thousand at the current exchange rate) in the United States.

“Printing” OLED

Typically, OLED panels are developed in large factories of companies like Samsung and LG. However, the research may eventually make it possible for hobbyist enthusiasts to make their own OLED screens at home.

“This is something we actually manufacture in a lab, and it’s not hard to imagine you could translate this to print all sorts of screens at home. […] in just a few years on a small portable printer,” said University of Minnesota professor Michael McAlpine.

The University had already carried out the printing of OLEDs, but they faced some difficulties along the way. This time they used spray printing for the active layers and extrusion printing for electrodes, interconnects, insulation and encapsulation — currently, the flexible OLED panel is capable of displaying human-readable text.

Image quality is still an issue, however, researchers have already revealed that they are working to offer screens with brighter and higher resolution. It is worth noting that there is still a long time for enthusiasts to be able to use the technology at home, as it literally costs the value of a car – electric and Tesla.

Samsung is preparing a smartphone that will be weaker than its predecessor two years ago. Galaxy M54 will receive SoC Exynos 1380

Samsung is preparing a smartphone that will be weaker than

Smartphone Samsung Galaxy M54 lit up in the Geekbench database. Unfortunately, as previously reported, he will not receive any SoC Snapdragon 888, although this is expected.

Samsung’s mid-budget novelty will receive the same platform as the Galaxy A54. Probably, the Galaxy A34 will also receive it.

We are talking about the not yet presented Exynos 1380, which will replace the Exynos 1280. In the benchmark, the new SoC scores 750 and almost 2700 points in single-threaded and multi-threaded modes, respectively. And this is almost the level of Snapdragon 778G, that is, this is an excellent result for a mid-budget smartphone. True, we are only talking about processor performance, and we do not yet know which GPU the new SoC will receive.

It is also worth noting that the Galaxy M52 was also based on the Snapdragon 778G, and the Galaxy M53 received a slightly less productive Dimensity 900. Thus, the Galaxy M54 model, at least in terms of the processor part, will be slightly inferior even not to its predecessor, but to the device two years ago.

Bullitt Group and MediaTek want to launch a satellite enabled smartphone

The British manufacturer Bullitt Group, which produces devices under the brands CAT and Motorola, intends to release a smartphone with satellite communications. They want to implement this project together with the Chinese chipmaker MediaTek.

Bullitt Group and MediaTek want to launch a satellite-enabled smartphone

It is assumed that the new smartphone will provide calls and text data via satellite, although it is not yet clear how this will work. The device itself will be released in the first quarter of 2023.

The novelty has been developed for two years, so the project is nearing completion. According to Bullitt Group co-founder Richard Wharton, previously the seamless integration of satellite communications into a smartphone was accompanied by problems, but now they are solved.

The new phone will be the first to use MediaTek’s 3GPP NTN chipset. The software will keep track of what type of connection is currently being used – Wi-Fi or cellular network. The connection to the satellite will be carried out only in the absence of both of these options.

It is claimed that the time to connect to the satellite and send a message is about 10 seconds. This is longer than a regular connection, but still pretty fast.

Note that Apple already has this and Samsung will soon have it.

The GeForce RTX 4080 can also be overclocked to incredible

Galax continues to prove that they are one of the best when it comes to overclocking graphics cards. After the departure of EVGA, Galax as a whole is probably the only company that places a strong emphasis on this direction.

The GeForce RTX 4080 can also be overclocked to incredible frequencies.  Galax RTX 4080 SG took the frequency over 3.6 GHz on the core

The GeForce RTX 4080 SG model was able to overclock to a frequency of over 3.6 GHz on the core. More precisely, we are talking about a frequency of 3615 MHz. This is slightly less than the RTX 4090 HOF at 3.8 GHz, but it’s still an incredible figure. Especially if you keep in mind that the GeForce RTX 4080 SG is no match for the HOF versions. At the same time, it is not yet known whether Galax will release the RTX 4080 HOF.

Galax, unfortunately, does not disclose overclocking details, but it can be assumed that we are talking about the use of liquid nitrogen, as in the case of extreme overclocking RTX 4090 HOF.
