Samsung may be forced to stop supplying OLEDs to Huawei due to US sanctions

The US government imposed sanctions against Huawei, which prevents the Chinese company to acquire components that use US-developed chips. According to a display from Korea, both Samsung Display and LG Display will have to stop supplying OLED displays to Huawei as these use drivers that are based US-developed technology.

Samsung Display has applied for a US US Department of Commerce license which will allow it to export the technology to Huawei. LG Display decided not to apply for the license, at least for now, as its OLED sales to Huawei are limited in any case.

Huawei starts to develop its own OLED driver ICs

According to reports from China, Huawei is starting to develop its own OLED driver ICs - and will start mass producing these chips later in 2020

It seems that Huawei aims to increase its self-sufficiency (especially with the US sanctions in place). In addition, the company believes its own chips will outperform the chips supplied to Huawei by third party and will enable it to improve its smartphone design.

MagnaChip reports an increase in AMOLED driver sales

OLED driver IC developer MagnaChip announced its financial results for Q1 2020. OLED DDIC revenue was $69.7 million, up 43.6% from last year and up 3.5% from last quarter. The company estimates that 8 new smartphones that adopt its OLED drivers were released in Q1 2020, and 9 just entered pilot production.

MagnaChip has a total of 16 OLED display drivers, almost double the number of drivers it had in its portfolio in Q1 2019. The company has started to develop OLED drivers for automotive products, which the company expects to to into production in the first half of 2021.

Magnachip reports record OLED driver sales, surpasses the 500 million OLED driver shipment milestone

OLED driver IC developer MagnaChip reported its financial results for Q2 2019, with revenues that exceeded its own guidance. One of the company's main growth drivers is OLED display driver ICs, which were up 7% from Q2 2018 to $73 million, the company's highest quarter ever.

Magnachip says that its OLED business benefited from six new OLED smartphone that were launched in Asia during the quarter, and the company also secured four new design wins. Most of its OLED driver revenues are from its 40-nm display driver, but its new 28-nm driver has entered mass production and will be a key revenue driver going forward.

Novatek Microelectronics expects its AMOLED driver IC shipments to double

Taiwan-based driver IC developer Novatek Microelectronics says that it expects shipments of AMOLED drivers will double from 3 million in Q1 2019 to 6 million in Q2 2019.

Novatek reported its financial results, saying that its last quarter was the best one in 11 years, as profits grew 34% from last year to $68.5 million. Growth at Novatek is fueled by strong demand for OLED drivers and TDDI chips.

MagnaChip launches its 28 nm AMOLED drivers

OLED driver maker MagnaChip launched its latest 28 nm OLED Display Driver IC for smartphone displays. MagnaChip says that it is using the world's most advanced process for OLED drivers, which enables it to achieve a 20% reduction in form factor compared to its previous 40 nm process.

In addition to the size reduction, the new process also enabled MagnaChip to reduce the voltage from 1.1V to 1V, which reduces the power consumption by more than 20%, and it also reduces the EMI levels (again, by 20%) which improves the phone's call quality.

MagnaChip launches a new initiative to co-develop mobile OLED display technologies

OLED driver maker MagnaChip announced a new initiative to co-develop new technologies for mobile OLED displays. MagnaChip is calling out to partners to combine their technologies (such as touch, stylus and fingerprint sensors) with the company's AMOLED driver technology.

MagnaChip's goal is to create reference designs and IP that will enable smartphone and other device makers to include new technologies that are compatible with MagnaChip's display driver ICs. MagnaChip announced its first partner - ELAN Microelectronic. This collaboration will mostly focus on stylus input technologies.

Solomon Systech launches the world's first TDDI touch PMOLED IC

Solomon Systech launched a TDDI (Touch and Display Driver Integration) IC for PMOLED displays. The new SSD7317 (the world's first PMOLED TDDI IC) integrates touch and display microelectronics in a single chip and can enable thinner and lighter form factors and reduced manufacturing time and process - and higher display quality (higher light transmission) and touch performance.

Solomon explains that the SSD7317 adopts a proprietary time multiplexing approach for display driving and in-cell touch detection, thereby enabling touch detection on traditional PMOLED display module with no modifications needed on the existing display module structure. Unlike traditional out-cell touch solutions (with separate display and touch IC) which need a dedicated ITO layer for touch sensor, the SSD7317 eliminates the touch ITO and PET substrate layers in addition to the bottom Optically Clear Adhesive (OCA).
