lcd display fading in stock

Resolution: Faded or incomplete segments indicate a poor connection between the LCD and the circuit board. To remedy, clean the LCD, the circuit board and the rubber elastomers that make the connections. Using isopropyl (rubbing) alcohol on a cotton swab, do the following:
If cleaning the monitor does not improve the display, an upgrade to a PM5 monitor will be needed. Replacement LCDs are no longer available for PM2/PM2+ Performance Monitors. The PM5 Monitor Retrofit Kit is available from Concept2.

It’s the polarizing film that’s stuck on the lcd panel which fades that causes the lcd display to look faded. You need to open up your watch and to peel off the polarizing film that’s stuck on your lcd display and put new polarizing film on the lcd panel.
Once an LCD display screen is cracked or broken, it cannot be repaired. A new LCD screen will have to be purchased. In the case of a desktop computer, a new monitor will need to be purchased.
If you crack your phone screen and do not fix it immediately, you could damage your LCD. Dust can also seep through the cracks on the screen and cause LCD screen damage. Water or liquid damage: If you drop your phone into water or some other liquid, some of it could seep into the phone and damage the LCD screen.
LCD (Liquid Crystal Display) is a type of flat panel display which uses liquid crystals in its primary form of operation. LEDs have a large and varying set of use cases for consumers and businesses, as they can be commonly found in smartphones, televisions, computer monitors and instrument panels.
Is LED or LCD Better for the Eyes? An LED display provides the option to dim the backlight, along with other eye comfort features. Not only that, it provides a wider viewing angle without harming image quality. Therefore, an LED display is far better for your eyes than an LCD.
This can greatly reduce the strain on your eyes. For example, in an office with normal brightness of 300-500 lux, the display brightness should be adjusted to around 100-150 cd/m2.

I"m using this (https://smile.amazon.com/gp/product/B07 ... UTF8&psc=1) 4 line LCD display. Does this type of display have a problem with burn in or anything like that? I"m trying to decide if I need to limit the time the display is on or if I can leave it on 24/7.
LCD panels will fade with time, but the device is likely to last a decade or more before you notice the fade, at least speaking from personal experience with monitors that are on 24/7 for the last decade at my place of employment.
One widely cited problem is that OLED displays don"t last as long: degradation of the organic molecules meant that early versions of OLEDs tended to wear out around four times faster than conventional LCDs or LED displays. Manufacturers have been working hard to address this and it"s much less of a problem than it used to be.
There are a lot of tricks that OLED TVs (and presumably mobile phones) are documented as doing to reduce the wear on OLED pixels, such as "resting" individual pixels by subtly dimming some whilst brightening adjacent ones and applying slight blurs or colour changes where lack of detail won"t be noticed. For example the whole "reduce blue light in the evening because it helps you sleep" colour shift may well be a chance for the display to give the blue OLED pixels a bit of a break as much as anything else
Traditional LCD display"s like you linked will work for many decades as long as they are not in direct sunlight and kept between 15°C and 40°C at less than 90%RH. Other environmental conditions can shorten the life span significantly. The LED"s used for backlighting, when used at moderate brightness, will also be usable for decades before dimming is noticeable.
The small inexpensive OLED displays do burn out rather quickly compared to other technologies. This statement from Adafruit for one they sell is dead on IME. https://www.adafruit.com/product/326
Please note that OLED displays are made of hundreds of...OLEDs! That means each pixel is a little organic LED, and if it"s kept on for over 1000 hours it"ll start to dim. If you want to keep the display uniformly bright, please turn off the display (set the pixels off) when it isn"t needed to keep them from dimming.
Wish I"d known that before I put my one OLED project into service (bought the OLED from eBay), in under two months the display started to get rather ugly with many pixels at varying brightness levels. Fortunately, after over two years with the display on continuously it hasn"t gotten too much uglier and it is still readable.
Those OLEDs aren"t designed for 24x7 operation and will degrade rapidly if left continuously on. They"re meant for cordless phones where the display is usually off. The yellow strip at the top is for a status bar.

Suddenly after updating my linux distro, my monitor is broken now. It is behaving strange. It"s showing white screen on boot, with a slow graphics and fading effect. White line are also visible on screen. Please have a look on attached video.

Some TV displays, such as LCD screens, use a backlight to illuminate the picture. If the backlight burns out or stops working, it will result in a blank TV screen.

There are number of cause for the LCD to get bad such as internal electrical contact problem, but what most people don’t understand is that if the CONTRAST of the LCD is getting down, the most likely cause is the “Liquid Crystal” substance itself were attacked by water (i.e. moisture).
This problem was intensively studied and tested when the LCD was first marketed for such application for digital watches, and some early digital watch maker engineer actually tested there watches by wearing there “watch under test” even during taking a hot bath!!!
Also if attacked by water (i.e. moisture) the power consumption of the LCD display itself will gradually increase, causing serious problem for a application such as watches which needs to be low power consumption for longer cell life.
This is the reason I am totally not interested in a film camera (must have a life span of at least 25+ years, not those one that goes old within 3 years) that have LCD on it.
