fading lcd display factory

(Bloomberg) -- Japan Display Inc., once one of Apple Inc.’s key suppliers, sees a new market for its liquid crystal displays after ceding the smartphones arena to rival OLED screens: the niche yet growing virtual reality business.

The Tokyo-based LCD specialist expects its favored display technology to become the standard for VR because it can achieve higher resolution than OLED while keeping costs reasonable. That advantage is imperceptible in mobile devices but becomes critical in the more demanding VR scenario.

Many of the first wave of headsets released five years ago used OLED screens -- or organic light-emitting diodes, the same as used across most flagship phones today -- for their responsiveness to fast-moving action, a common feature of gaming experiences. But major players such as HTC Corp. and Facebook have moved to LCDs for their latest products, betting on the more economical standard to improve the user experience and immersion. Industry researchers at Omdia saw LCD adoption rise in 2020 and forecast the technology will dominate the category over the next five years.

One important holdout remains: Sony Group Corp. plans to use Samsung Display Co. OLED panels in its next-generation PlayStation VR goggles, according to people with knowledge of the matter. The Japanese console giant sold more than 5 million units of the original PS VR, launched in 2016, and is aiming to release the successor in the holiday period next year, the people said, asking not to be named discussing internal plans.

To grab a bigger share of the market, JDI is working to convince VR companies it can solve two of their biggest hurdles: display quality and cost. Because VR goggles place the screen so much closer to the human eye, they require higher resolution and clarity than mobile screens, achieved by packing pixels closer together. JDI is capable of producing displays with 1,200 pixels per inch, more than double the typical density of top-tier phone panels, according to its chief VR headset engineer, Yoshihiro Watanabe.

The threshold for a high-quality VR experience is to have a display with at least 1,000 pixels per inch, Watanabe said, adding that JDI is one of the few display makers -- if not the only -- that can mass-produce such panels at a reasonable production yield.

JDI was created in 2012 by the combination of the display-making units of Sony, Hitachi Ltd. and Toshiba Corp., with much of its revenue since then coming from mobile handsets, especially iPhones. More than half of its total sales used to come from the Apple business, but the iPhone maker’s adoption of OLED technology left the company reeling.

Unable to develop its own OLED panels to a competitive level with leader Samsung Display, JDI has seen its revenue from phones drop from 838 billion yen ($7.7 billion) in the year ended March 2016 to an expected 81 billion yen this fiscal year. The firm sold the factory it had used mainly to produce panels for Apple to Sharp Corp. last year.

It’s difficult to say that LCD is in all cases superior to OLED for VR, Hayase said, because OLED offers better contrast in addition to faster response times. The key for JDI will be to establish a solid footing in the industry by addressing customer needs that other suppliers would turn down owing to the small market size, he added. JDI has experience of doing that from its business supplying display panels for digital cameras.

We must verify whether the problem is the display screen of the laptop, video card (GPU), or video settings on the computer. A straightforward way to identify this is to connect the laptop to an external monitor or TV.

If the issue persists on the external monitor, it may be an issue with the video card (GPU) or video settings and not the laptop LCD panel. Go to verify display or video issues in Windows Safe Mode. Otherwise, go to the next step.

Performance issues may occur if there is any damage to the LCD screen. The display may stop working, work intermittently, flicker, display horizontal or vertical lines, and so on, if there is damage to the display screen.

Dell laptops have integrated diagnostic tools that can determine if the screen abnormality is an inherent problem with the LCD screen of the Dell laptop or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry images, horizontal or vertical lines, color fade, running a diagnostic test on the LCD helps identify if the issue is with the LCD panel.

Press and hold the D key and turn on the computer to enter the LCD built-in self-test (BIST) mode. Continue to hold the D key until you see the entire screen change colors.

If you do not detect any screen abnormalities in the integrated self-test mode, the LCD panel of the laptop is functioning properly. Go to the Update the video card (GPU) driver, monitor driver, and BIOS section.

If you notice any abnormalities in the LCD built-in self-test mode, contact Dell Technical Support to learn more about repair options that are available in your region.

Display settings like brightness, refresh rate, resolution, and power management may affect the performance of the LCD screen on your Dell laptop. Changing or adjusting the display settings can help resolve several types of video issues.

If the diagnostic tests on the LCD panel and the video card (GPU) passed, it is most definitely an issue that is related to software that is installed on the computer. If the above troubleshooting steps did not resolve the issue, you may try to restore the computer to factory default settings as a last resort.

Have you ever left your TV or monitor on for days, stuck on the same image? You return to your screen, only to find an image burned into the display. No matter what you do, it won"t go away. It is a permanent image burn.

Why do monitors and TVs get image burn? Why can"t manufacturers prevent LCDs and plasma screens from a burnt image imprint? Moreover, what can you do to fix an image burn?

Before flat-screens and crystal displays, most TVs and monitors featured CRT (Cathode Ray Tube) technology. In CRTs, individual pixels comprise a red, blue, and green phosphor component. Depending on the intensity of each phosphor component, the pixel appears to the human eye as a unique color.

Plasma displays use plasma, a gaseous substance containing free-flowing ions. When the plasma is not in use, the particles in the plasma are uncharged and display nothing. With the introduction of an electric current, the ions become charged and begin colliding, releasing photons of light.

LCD and LED do not work in the same way as CRTs, either. LCD and LED screens use backlit liquid crystals to display colors. Although manufacturers market screens using LED and LCD, an LED screen is still a type of LCD. The white backlight filters through the liquid crystals, which extract particular colors per pixel.

LCD and LED displays don"t suffer from the same type of image burn as CRTs and plasma screens. They"re not completely clear, though. LCD and LED screens suffer from image persistence. Read on to find out more about image persistence.

Before you can fix screen burn-in, take a second to understand why these images burn in the first place. LCDs and LEDs don"t suffer from burn-in as seriously as plasma screens. But static images can leave an imprint on both display types if left alone for too long. So, why does image burn happen?

LCD and LED screens can also experience image burn, though the image burn process can take longer to develop into a permanent issue. In addition, LCD and LED screens suffer from another issue, known as image retention (also known as image persistence or an LCD shadow).

Image retention is a temporary issue that you are more likely to notice before it becomes a permanent issue. However, proper image burn can still affect LCD, LED, and OLED screens.

The other thing to consider is that LED and OLED image burn-in, when it happens, is irreversible. That"s because of how LED and OLED screens work. Individual pixels within an LED display decay when they emit light.

Image burn-in fixes exist for LCD and plasma screens. How effective an image burn-in fix is depends on the screen damage. Depending on the length and severity of the image burn, some displays may have permanent damage.

My personal rule of thumb is to turn off the display if I plan on being away for more than 15 minutes. That way, it is difficult to get caught out, plus you save yourself money on electricity costs and monitor or TV wear and tear.

If your plasma or LCD screen already has image burn-in, you can try turning on white static for 12 to 24 hours. The constant moving of white-and-black across your screen in random patterns can help remove the ghost image from your screen.

Pixel-shift constantly slightly adjusts the image on your screen, which varies the pixel usage to counteract image burn. You might have to enable a pixel or screen shift option in your screen settings. Pixel-shift is a handy feature for LED and OLED screens that cannot recover from image burn and should help counteract an LCD shadow.

While the Deluxe version uses advanced algorithms to repair burned screens and prolong plasma and LCD longevity, the official site is no longer up and running, and there is no way to download the full version officially.

If the screen flickers, make sure the display settings in Windows match the native resolution and refresh rate for the display. Find the native resolution of a flat panel display on the box, in the specifications, or in the printed material that came with the display. Some common native resolutions are 800 x 600, 1024 x 768, 1920 x 1200, and 1680 x 1050. The most common refresh rate for LCD displays is 60 Hz. This normally cannot be changed for flat panel displays using Plug and Play settings. However, if you are using special video software to increase or decrease the refresh rate, change the refresh rate to match the default refresh rate specification of the display.

If your screen flickers in Windows 10, it is usually caused by incompatible apps or display drivers. To find out whether an app or driver is causing the problem, check to see if Task Manager flickers. Then, based on that information, you"ll need to either uninstall the app or update the display driver.

Check the environment around the display. Displays are sensitive to magnetic fields. Speakers, florescent lights, fans, cell phones, radios, and any other electrical device can cause flickering. Temporarily move electrical items away from the display to see if they is producing a field that causes the flicker.

To see if the video coming from the computer is causing the problem, temporarily connect the display to another computer, such as a notebook computer.

If the flicker is gone when the display is connected to another computer, the graphics adapter hardware on the first computer might need to be upgraded to use the display.

The liquid crystal display (LCD) plant operating rate is expected to recover from next month which hit the bottom due to a decrease in TV demand. TV manufacturers are using up their inventories, therefore they have to resume on the LCD supply. A market research firm, Omdia, predicted on the 18th that the operating rate of LCD manufacturing plants in the global display industry would rise up to 73% in August. They are forecasting a rebound from the operating rate of 70% in June and 69% in July. The LCD plant operating rate was the lowest in 10 years since February 2019 (77%).

By July, the operating rate fell down to the 60% level due to falling TV and home appliance demand. Samsung Electronics focused on consuming their inventory of finished TV products. It is known that Samsung even temporarily suspended LCD purchases from global display manufacturers such as BOE, HKC, and Sakai SIO International.

The decline in LCD plant operating rate is due to the fading of the ‘COVID-19 special’. The global TV industry saved several months" worth of inventory as TV sales increased due to COVID-19. As the COVID-19 special disappeared, they focused on using inventory and reducing new orders.

As TV manufacturers used up their inventories, LCD operating rate is expected to recover up to 70% from August. It is expected that the supply of LCD TV to Samsung Electronics will resume and the operating rate of large LCDs will increase focusing on China. The operating rate in September is expected to remain at 77%, although it is not at the level of the previous year. Even if the global LCD plant operating rate recovers, South Korean companies plan to reduce production due to deterioration in profitability. LG Display has decided to reduce production of large LCD displays by up to 20% in the second half of this year. Samsung Display stopped the LCD business ahead of LG Display. On the other hand, Samsung Display and LG Display have decided to expand production of organic light emitting diodes (OLED) instead of LCD.

"The characteristic of liquid crystals that makes them ideal to be used in display screens is that they align themselves when an external electric field is applied to them. To be more technically specific, these liquid crystals are sandwiched between two pieces of polarized glass ...".

How long will your LED display last? In nearly every industry, from retail businesses to concert halls to corporate centers, decision makers need to evaluate the return on investment (ROI) of their LED signage. In most cases, potential buyers go straight to the obvious place: the LED manufacturer’s spec sheet. The industry standard for LED lifespan is 100,000 hours, or about 10 years, and most people assume that’s how long their display will last. But it’s not quite that simple.

The 100,000-hour figure assumes that every diode will be running at full brightness, consistently — which, on an LED screen, is virtually never the case. The lifespan figure can also be misleading because it indicates when a diode degrades to half-brightness, not completely dark. Many other variables affect an LED display’s lifespan; you can’t rely solely on the number on the diode spec sheet.

“The reality is, your screen can often last significantly longer than 100,000 hours,” says Kevin Izatt, a senior product manager in Samsung’s Display division. “We’ve had displays that have been up for 15-plus years with more than adequate brightness. Because the diode is actually only one factor in the lifespan of your LED display.”

The biggest contributor to diode degradation is heat. As you increase a diode’s brightness, it produces more heat. Your display’s physical environment also contributes to the temperature of the diodes, especially for outdoor displays.

The quality of your display’s power supply — and how hard it drives the diodes — can have a significant impact on your screen’s lifespan. The other components being powered, such as fans and electrical components, have their own lifespans as well, which are also impacted by the power supply.

“Fans are mechanical; they break down,” explains Izatt. “And similar to your computer, the electrical components don’t last forever. Together, these factors all contribute to the lifespan of an LED display. Looking at just the diode lifespan doesn’t give you the complete story — almost always, another part will go out first.”

It’s easy to see why: The circuit boards powering the display release heat, and that heat needs to go somewhere. Without a strong design, thermal stress will degrade the life of the display, except for the highest-quality parts — optimal conditions notwithstanding.

That’s not to say you should hold back on displaying rich, vibrant colors — after all, that’s what LED does best. But it does factor into your product’s life expectancy.

To help businesses transition from LCD to longer-lasting LED signage, Samsung has launched a trade-in program. Samsung will come on site to remove your existing display and provide a discount on a new LED bundle kit.

Traded-in LCD displays that are still operating will be refurbished and resold, and your business will receive a cash rebate. Nonworking displays will be recycled and their parts reused.

You can’t rely on the number on the diode spec sheet; the lifespan of your LED display depends on many more factors. “Overall quality has a tremendous impact on the life of the display that diode specs just don’t take into account,” says Izatt. Your best bet is to look at the purchase holistically and invest in a top-tier product.
