lcd display fading factory

I bought a 70d about two weeks ago, and last night I noticed that the top LCD screen was appearing to go out. Meaning, the individual "bars" (for lack of a better term) that make up each letter and number were intermittantly on or off. So, for a letter "0" that might normally be represented by 6 pixel/bars, five of them would be out. Half of the battery pixels were out.

I immediately assumed the battery was dead, so I charged it, and when I plugged in the fully charged battery, I noticed I had the same problem. When I went to the battery menu on the main menu, it did appear fully charged, but I still noted that every charactor on the top LCD screen was missing parts on the display. The camera still appears to function normally, with the exception of the top LCD sreen, and the viewfinder information screen. The screen in the bottom of the viewfinder does the same thing.

Unfortunately LCD fade in sunlight/heat is not uncommon, generally. I have an LCD display on my my pool filter controller that does exactly the same. There are many reports of similar effects in different products from car dashboards to GPS units.

I have a cluster from by Golf that has a dead full pixel display. It started off with dead lines (mostly vertical), got worse with hotter days, then died completely (with a little help from my attempts to fix it). It seemed to me when I investigated that the bond between ribbon and display was failing on indvidual lines.

If you figure out how to bond a new display to the circuit board, I"d be interested in getting this cluster repaired so I"d have a spare for when the cluster in the car goes dead (it was the former spare). Of course, if somebody comes up with a good group buy on these again...

(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.
