Doing This Before Bed Can Mess with Your Metabolism—and It Has Nothing to Do with Food

We've covered the best bedtime snacks for metabolism along with the worst pre-bed bites. (And ICYMI, no, eating before bed won't automatically lead to weight gain!)
Another tip we often mention to make it easier to fall asleep? Shutting down our tech gadgets about 2 hours before bed. In addition to making it easier to turn in, this habit may also help our metabolism, according to new research published in the journal Scientific Reports. Extended exposure to blue light at night may trigger metabolic changes that, over time, lead to weight gain.
"Energy metabolism is an important physiological process that is altered by light exposure," senior author of the study, professor Kumpei Tokuyama, tells University of Tsukuba Research News. "We hypothesized that compared with LEDs [light-emitting diodes], OLED [organic light-emitting diode] exposure would have a reduced effect on sleep architecture and energy metabolism, similar to that of dim light." FYI: Sleep architecture refers to a normal sleep pattern.
LEDs have spiked in popularity in the past decade or so due to their energy savings— Energy.gov reports that ENERGY STAR-rated LEDs use 75% less energy and last 25 times longer than typical incandescent lights. In addition to bulbs, LEDs are now found in many flat-screen TVs, computer monitors, phone and tablet screens. It's also a strong source of blue light, a form of light wave between 380 to 500 nanometers, that's very high energy and tough for the retina to block, say UC Davis Health experts. As a result, it can lead to eye strain, alertness and potential vision challenges (with extended exposure over the lifespan).
Polychromatic white LEDs emit a large amount of blue light. In contrast, OLEDs emit polychromatic white light that contains less blue light. So professor Tokuyama and his team set out to organize a small study to examine the difference.
To do so, they exposed 10 male participants to LED, OLED or dim light for 4 hours before they slept in a metabolic chamber. As the men slept, the scientists measured core body temperature, energy expenditure, fat oxidation and the levels of a measure of melatonin (a hormone involved in sleep) called 6-sulfatoxymelatonin.
"The results confirmed part of our hypothesis," professor Tokuyama explains in the University of Tsukuba Research News study recap. "Although no effect on sleep architecture was observed, energy expenditure and core body temperature during sleep were significantly decreased after OLED exposure. Fat oxidation during sleep was significantly lower after exposure to LED compared with OLED."
Fat oxidation was also related with 6-sulfatoxymelatonin levels after exposure to OLED, which led the researchers to believe that the impact of melatonin on energy metabolism varies depending on the type of light exposure.
"Light exposure at night is related to fat oxidation and body temperature during sleep. Our findings suggest that specific types of light exposure may influence weight gain, along with other physiological changes," professor Tokuyama adds.
Daytime exposure appears to be less harmful to sleep quality and metabolism, based on current medical knowledge.
This research is in line with past studies on light exposure, sleep and metabolism and while larger-scale and more extended studies are needed to verify these results, this is certainly a solid reminder to step away from Netflix and endless Instagram scrolling and pick back up with our nighttime reading routine. (Which just so happens to be correlated with making healthier food choices and earning more money, too!)
And it's another nudge that those trendy blue light glasses might be more than a trend. Affordable specs like TIJN Blue Light-Blocking Glasses (buy it: $12.99, Amazon) can help protect the eyes from the most taxing forms of blue light. |

| To: RitzHuskie who wrote (26160) | 7/14/2021 10:42:45 AM | | From: mirage2017 | | | | This is from Slackers post in early June. Slacker mentions the guidance comment at the end; to me its very telling.
IMO, Sid's most recent comments at the Cowen conference about blue are both revealing and incoherent. Unfortunately, there is no transcript, but it is the first few questions of the replay. The analyst did a good job of continuing to try and get answers on blue.
wsw.com
- This is the first time I have heard management acknowledge the idea that customers have better access to host materials to create emitter layers. He says that customers can get better results than UDC can get in their own labs.
- He continues to say that the emitter doesn't hit "commercial specs" today but if lifetime is the issue and the choice of hosts can make a >10x difference in lifetimes, then what does that mean? If Samsung finds a host that increases lifetime by 50x, would that still fail to hit the required lifetimes? 100x?
- The emissions peak is right around 460nm which has been the goal for years. Maybe that has changed? Sid stated that power efficiency is the least important of the three primary specs (lifetime, color, and efficiency).
Overall, he says that customers are all sampling blue and trying to optimize it for their own stacks but also says that customers are waiting for the emitter to hit commercial specs. I have trouble squaring that circle.
Also of note, he acknowledges how conservative the guidance is. |

| From: jexzz | 7/14/2021 1:39:03 PM | | | | | | This was from Goldman recently on chip shortage:
Supply chain issues are indirect and having limited impact for now. OLED does not appear to be seeing any impact on its business and no real direct impact in terms of constraints, and the company does not believe that customers are buying safety stock or building inventory. In terms of its own supply chain, the company did note that it is still watching the pricing trends for one of its raw materials - iridium - which OLED noted has seen a meaningful price increase over the past few years (e.g. $400 per troy ounce to over $6,000 at peak, though down since then). That said, the company has been building inventory steadily on iridium and said that it has enough stock for several years worth of needed supply, and thus does not see any constraints in the near-to-medium term. |

3 things needed for Samsung and LG to expand IT OLED production
Gi Jong Lee ?? 2021.07.15
Customers, Gen 8.5 FMM technology and feasibility
 Image: Apple
OLED is widely used in smartphones and smart watches, but hardly in IT applications, or for tablets, notebooks and monitors. Liquid crystal display (LCD) is still the dominant panel used in non-smartphone products.
South Korean display equipment maker had hoped for Samsung Display and LG Display to expand their spending on their production capacity for IT OLED panels, but there has been no related news announced by the two companies for over a year.
Three things will be needed for the pair to start aggressively expanding their IT OLED production capacities: a stable, volume demand from customers, technology to realize a new emission layer and economic feasibility.
Multiple sources that TheElec talked at Samsung Display and LG Display say customer is the foremost thing needed.
Expanding panel production capacities requires billions of dollars in spending, which require a thorough review of market demand, line operation rate and profitability.
According to market research firm Omdia, this year, 5.5 million tablets will use OLED panels; in 2022 this will expand to 6.1 million units. OLED application in notebooks will also expand from 3.6 million units to 4.3 million units over the same time period. This is a relatively high growth rate and the panels are bigger meaning they will fetch more in price per unit.
However, in absolute volume, OLED panels for smartphones dwarfs these figures. According to Omdia, a total of 585 million units of OLED smartphones will be shipped this year. Smart watches that use OLED panels will reach 120 million units in shipment at the same time.
OLED use in IT products will gradually increase, one of the sources said. But display panel companies will need secure enough volume orders from customers before executing any large spending in the sector, they said. Another one of the sources said Samsung Display and LG Display can currently convert exiting lines with low operation rate into those for IT OLED panels with the current demand that don’t require large investments.
Another requirement for large spending in the sector will be technology. The OLED industry is currently focusing on two stack tandem structure for OLED panels __ where two layers of red, green and blue emission layers are stacked __ as well as fine metal mask for super large mother glasses.
Two stack tandem is shown to double the luminance in OLED panels and offer four times the life span compared to singe tack. The sources said Apple had asked its South Korean display panel supplier to use the two stack tandem structure for the OLED panel it plans to use for an iPad launching in 2023. Two stack tandem is deemed need for OLED panels in tablets as the device is used longer than smartphones that average two to three years of use, the sources said.
Samsung Display is planning to apply the single stack structure for the OLED panels it plans to supply for iPads next year. The OLED panels it supplies for Samsung Electronics’ Galaxy Book Pro series also uses a single stack structure.
LG Display, which is highly likely to supply OLED panels for the iPad launching in 2023, has already applied the two stack tandem structure in automotive OLED panels.
Fine metal mask, or FMM, is also a challenge. A FMM that can used for Gen 8.5 substrate (2200x2500mm) over the current Gen 6 (1500x1850mm) is needed. This is because of economic feasibility. FMM is used to deposit organic material on the substrate. A larger substrate means more panels can be manufactured per substrate at the same time. More of the substrate is used without being wasted, especially for larger panels.
For example, a Gen 6 substrate can make 48 units of 13.3-inch panels. A Gen 8 substrate will be able to make 96 units. This increase is productivity can drastically reduce cost for display makers.
Samsung Display is more likely start expanding its spending on IT OLED panels than LG Display, the sources said.
Samsung Display has recently increased its IT OLED panel production target for this year from 4 million units to between 5.5 million to 6 million units.

In order for LG Display to supply organic light emitting diode (OLED) panels for TVs to Samsung Electronics, there has been an observation that it should hurry up to invest in the 10.5th generation (2940 × 3370 mm) fab.
Choong-Hoon Lee, CEO of UBI Research, a market research company, said at a display technology seminar held online on the 16th, "In order for LG Display to supply OLED panels for TVs to Samsung Electronics, it will need 10.5G investment this year."
The timing of resuming investment in 'P10', LG Display's 10.5th generation OLED fab in Paju, is currently unclear. LG Display has been responding to increased OLED demand by operating the Guangzhou OLED line in China since the second half of last year.
CEO Lee Choong-hoon said, "Even if Samsung Electronics does not join as a customer, LG Display will have to invest in the 10.5th generation next year at the latest." "Otherwise, OLED supply for TVs in 2024 will fall short of demand," he emphasized.
He added, "If we do not change the existing LCD fab to 10.5G OLED, it is time to make a new investment."
LG Display is expected to operate large LCD lines in Korea at least until this year. As LCD prices are not expected to drop significantly next year, many view that LG Display will maintain its large LCD line next year.
According to UBI Research, the demand for OLED panels for TVs is increasing rapidly recently. In the second quarter of this year, LG Display's TV OLED panel shipments were counted as 1.8 million units, up 185.7% from the same period last year.
LG Display is expected to ship 7.2 million OLED panels for TV this year. It is suggested that this number will increase to 8 million units next year and 10 million units in 2024.
CEO Lee said, "If Samsung Electronics receives OLED panels from LG Display and makes TVs, LG Display's shipment of 10 million large OLEDs can be advanced by one year." “Eventually, 10 million shipments will be possible in 2023,” he explains.
In addition, CEO Lee said that OLED panels will rapidly spread beyond smartphones and TVs to tablets and laptops. When Apple's iPad with Samsung Display's OLED panel is released next year, OLED adoption is expected to become common in high-end tablets.
It also has great potential in the notebook market. About 800,000 laptops with OLED were shipped last year, but 2 million units have already been shipped in the first half of this year alone. About 4 million OLED notebooks are expected to be shipped this year.
CEO Lee predicted, "From this year, Samsung Electronics will lead the high-end notebook market with OLED notebooks."

| From: Ravid.Ron | 7/16/2021 3:49:40 AM | | | | | | LG Display, Apple's foldable phone panel development 'cruising well'
LG Display is in the process of developing a folding (foldable) display to be supplied to Apple. Apple is expected to launch a foldable iPhone in 2023.
According to UBI Research on the 16th, LG Display and Apple started joint development of foldable organic light emitting diode (OLED).
On this day, Lee Choong-hoon, CEO of UBI Research, said, “Apple has entrusted LG Display with its own patents related to foldable OLED. LG Display is continuing its development tasks.”
The foldable panel that the two companies are collaborating with is an in-folding method that folds inward. A technology that makes the folded part thin by an etching process is applied. The size is estimated to be around 7.5 inches.
Previously, LG Display supplied foldable panels for laptops to Lenovo. It is still for smartphones. LG Display is said to have also formed an organization related to cover windows that protects foldable displays last year.
In the meantime, Samsung Display has been leading the foldable market. Starting with the 'Galaxy Fold' released by Samsung Electronics in 2019, it exclusively supplied panels such as the 'Galaxy Z Flip' and 'Galaxy Z Fold 2'. Samsung Display will also be in charge of the next foldable phone that Samsung Electronics will be unveiling in August.
The industry expects Apple to release a foldable product around the next year or so. Apple relied heavily on Samsung Display in the existing smartphone OLED field. Recently, we have dualized our partners with LG Display. Foldable also plans to lower the proportion of specific companies through LG Display.
Meanwhile, in the second half of this year, China's Xiaomi, Oppo, and Vivo, and the US' Google will also release foldable phones. As more products are released, the foldable market itself is highly likely to expand. According to market research firm Omdia, foldable display shipments in 2021 are estimated to be around 13 million units. This is two to three times higher than the previous year.

Large OLED panels to likely face shortage in 2024
Gijong Lee ?? 2021.07.16
According to UBI Research
 Image: UBI Research
There will likely be a shortage of large-sized OLED panels used in TVs starting in 2024, UBI Research CEO Choong Hoon Yi said.
Yi based his forecast on the production capacity for large-sized OLED panels and t here expected demand going forward.
Demand for large-sized OLED panels is expected to be around 7.2 million units this year, but this will increase to 10 million units in 2023 and 12 million units in 2024, Yi said at an online conference on Friday.
LG Display is currently the sole supplier of large-sized OLED panels. Its current production capacity for the panels is around 10 million units a year. It has production lines in Paju, South Korea and Guangzhou, China.
Unless the company expands its capacity, demand will outpace supply by 2 million units in 2024, the CEO noted.
Yi said LG Display may commence expansion of its capacity earlier than scheduled in light of this possibility.
Last year in January, the South Korean display panel maker had said it plans to start spending in expanding its Gen 10.5 (2940x3370mm) OLED production line in 2023.LG Display currently manufactures its OLED panels in Gen 8.5 (2200x2500mm) OLED lines. Using the larger Gen 10.5 substrate can increase productivity for the firm. A Gen 10.5 substrate can make eight 65-inch panels or six 75-inch panels. In contrast, a Gen 8.5 can make six 55-inch panels and three 65-inch panels.
Yi said LG Display will start investing no later than next year as it will take more time to secure the needed yield rate in a Gen 10.5 line, considering that the firm has no prior experience using such a large substrate in production.
However, the CEO also said LG Display doesn’t necessarily need to focus on Gen 10.5 and can upgrade its existing Gen 8.5 lines to expand production capacity.
Yi also said his demand forecast is based on those from LG Electronics, Sony and other exiting OLED panel customers.
If Samsung Electronics were to start procuring large-sized OLED panels from LG Display, the shortage will happen sooner by a year, he noted. In this scenario, LG Display will need to start expanding its capacity this year.
Meanwhile, the UBI Research CEO also said 1,8 million units of large-sized OLED panels were shipped in the second quarter, an 186% increase from the second quarter of 2020. It was also a 13% increase from the first quarter of 2021. LG Display began operating its Guangzhou OLED plant in the third quarter of last year and its capacity has increased since then, Yi said.
The tablet market will also lead to expanded shipment of mid-sized OLED panels, the CEO said. Previously, the launch of foldable products was expected to cannibalize the tablet market but Apple was delaying its foldable phone launch and planning to introduce a OLED iPad next year, Yi said.
For OLED panels used in notebooks, shipment reached 2 million units in the first half of this year, he said. A minimum of 4 million units is expected to be shipped this year. Samsung Display is the only company that manufactures notebook OLED panels.
