CSoT breaks ground on its upcoming T7 fab, which includes a printed OLED TV line

China-based display maker CSoT held a ceremony yesterday as it started construction on its upcoming T7 large-area display production fab. The T7 fab, which has a total cost of around 42.7 billion Yuan ($6.15 billion USD), will produce both LCD and OLED display.

Total capacity in the T7 line will be 105,000 monthly substrates (according to our information, the OLED capacity will be 20,000 monthly substartes). The T7 OLED line will use IGZO backplanes and inkjet printing deposition. CSoT's plan is to start production by the end of 2020 - with real mass production starting in 2021.

Users complain about the quality of LGD's pOLED used in the Google's Pixel 3

Google's 2017 Pixel 2 XL was one of the first phones to adopt LG Display's pOLEDs (6" 1440x2880) - and initial reviews of the display were rather dismal - as both reviewers and customers complained about bad color reproduction, graininess and problematic viewing angles. Many users also reported serious image retention issues.

Google Pixel 3 vs. Pixel 1 - pink hue problem

In 2017, Google used Samsung's Super AMOLED displays in the smaller in 2017. This year, for the 2018 Google Pixel 3, Google chose SDC's 6.3" 1440x2960 Super AMOLED for the larger Pixel 3 XL - with proved to be a top-notch display. For the smaller Pixel 3, Google picked LG Display's 5.5" 1080x2160 - probably hoping that LGD managed to improve its displays - and most importantly its quality controls.

Researchers use printed red and near-infrared PLEDs to create a flexible blood oxygen sensor

Researchers from the University of California Berkley developed a new flexible and lightweight blood oxygen sensor that can map oxygen levels over large area. The sensor uses an array of red and near-infrared OLEDs, together with organic photo-diodes, printed on a flexible substrate.

The research was supported by Cambridge Display Technology, which means that these red and near-infrared printed OLEDs use polymer emitters (PLEDs).

Google details OLED power consumption, shows how Android's dark mode can help extend your battery life

As OLED is an emissive display technology, an OLED pixel only draws power when it is used - and the brighter it is, the more power it consumers. This of course means that adopting a dark UI is better for your device's power life.

Power consumption on the Google Pixel (2016) per color

During Google's recent Android Dev Summit, the company detailed the power consumption of the OLED display used in its 2016 Pixel smartphone (an SDC FHD 5" AMOLED). As you can see in the image above, the power consumption is different for each color (with red being the most efficient color and blue the least efficient). Surprisingly the display draws quite a bit of power even when completely black.
