I have a small DAP (digital audio player) with a an early i-phone-size screen (it is not not a touch screen, however). Have had this DAP since 2010. A year or two after purchase, it developed one of those black blotches (10 mm dia.) in the middle of the screen. It moves around a bit, but mostly stays in one place ... same size ... all these years later. MOST CURIOUS is that the black blotch will move around but its last positions are completely normal. The DAP is still on it orig battery and constantly plugged into 5v USB for recharge, now going on 11 years (I have to leave it cont. plugged into recharger because the DAP weirdly developed a 50ma continuous/internal draw about the time the LCD blotched) I can use it for 3-4 hrs, on battery power, daily if needed, functions perfectly well, but back to charger it goes after use.

Liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals. Liquid crystals do not produce light directly, instead using a backlight or reflector to produce images in colour or monochrome.

Is your obsessive side getting twitchy yet? Before we discuss upping your Xanax prescription, let"s review how the DSE demon begins its possession of your beloved screen.

Still, DSE may afflict cheaper versions, particularly if the anti-reflective coating on the glass that overlays the screen is of low quality or poorly applied. Furthermore, as the display ages, the phosphors in the screen may begin to wear out or malfunction, all of which can contribute to less uniform images, which is often apparent particular in scenes with fast panning shots.

In LCD and LED TVs, DSE is typically a bigger issue, one that"s due to the way these units are illuminated. Before we proceed, it"s worth mentioning that although marketing-speak often treats LED and LCD TVs as completely different technologies, they"re not different beasts.

LED units could be more accurately described as "LED-backlit LCD televisions," but salespeople and consumers alike are too lazy to utter that tongue-wearying phrase while haggling in a big-box store. What"s important to realize is that both categories rely on LCDs (liquid crystal displays), which act as shutters that either block light or allow it to pass, depending on the image that"s being rendered on the screen.

There are a variety of factors that affect LCD quality, notably illumination source. Older LCD TVs, for example, used multiple cold cathode fluorescent lamps (CCFL) to light LCDs from the rear. They provide generally smooth and even illumination, but they make the final product rather bulky.

More modern TVs rely on LEDs (light-emitting diodes) as a light source. Some models have what"s called full-array backlighting, in which the LEDs are stationed in regular intervals behind the screen, creating even lighting and excellent picture quality.

Other models incorporate what"s called edge lighting, which positions the LEDs along the edges of the screen. In general, the overall picture quality isn"t quite as good as a backlit screen, but manufacturers still use it because it allows them to build substantially slimmer TVs.

If you"ve ever pressed a little too hard on your smartphone or computer screen, you"ve likely witnessed a bit of discoloration, clear evidence of how sensitive LCDs are to physical pressure. Now, picture a huge manufacturing facility that cranks out thousands of these units per week. It"s easy to see how a bit of mishandling could alter the screen"s consistency.

The same goes for shipping. Some units travel long distances in cargo boxes, and then take bouncy rides in your car to their final resting place on your living room wall. That"s a lot of opportunities for tiny mishaps to affect LCD uniformity.

I have a Latitude E5500 series with a matte screen. It is almost 3 years old. The pixels along the top and side edges of the screen have slowly been going black. The top edge had lost up to 1/2 inch of display in some places. (see picture 1 from two weeks ago) Today there is a large black half circle at the top that is six inches wide and an inch thick (see picture 2). Strangely, some of the top edge that was black before now works again..

Do you think that replacing the screen will fix this? Or is this a different problem? It is not under warranty any more so I may try to replace it myself. I see a video on YouTube about that. Any suggestions?

The LCD panel will be connect to a driver board that is part of the panel, take a look on that one and see what you find. Post some good images of that board with your question so we may be lucky and find some sort of schematic etc. I would even contemplate on getting a universal driver for the panel just to see if the same issues are present when every board from the TV is disconnected. Sounds like a lot of work and maybe even some $$$ foolishly spend but I do not like to concede defeat.

Had camera for 8 days,, it just started displaying sporatic black blotches on LCD picture in view mode. Contacted Canon support, and was told to send it in for repairs and that they have not heard of this problem. Camera has not fallen or had any abuse whatsoever. Has anyone experienced this problem?

That is not normal in that it wouldn’t be made that way, but it’s normal since it’s understandable how it could happen. That is a cosmetic issue with the LCD panel. Without a physical inspection or examining the panel, my best guess is the layers are compressed physically. No need to repair it until you can’t or won’t abide by the color shift or the area just stops working.

As to the coming and going, If you carry your Mac in the book bag or it could be getting otherwise squeezed, that would explain why the color moves around in the dissipates as the glass and plastic layers reset themselves. Like a thin film of oil or soap on water, you are seeing a rainbow of diffraction and refraction as the light and LCD interact with each other.

Minute dots( bright dots and/or dark dots as seen above) may occur on a LCD. These dots are called Defective pixels (quoted from Wikipedia)". These dots may or may not stand out according to the colors displayed. It is a characteristic of LCDs and are not a defect and cannot be completely avoided with todays manufacturing technology.

As often as you use your smartphone, it’s almost inevitable that you’ll eventually drop it. You may be extremely careful, but it only takes one fumble for your phone to tumble. While iPhone screens are designed to withstand impact, you might still end up with a shattered screen.

The good news: a broken screen doesn’t mean your phone is kaput. In fact, if only the glass is broken, the fix is quick and inexpensive. The bad news: if the LCD screen is broken, you’re looking at a pricier repair.

If you’ve looked into replacement parts, you’ve likely come across two very different options: a glass screen, and an LCD screen. While the first option is cheap, the second is definitely not. Here’s the difference:

1. The glass screen is the exterior layer on your phone’s display. While it is specially engineered for durability, it’s still just glass (between layers of plastic film), which is why it’s not very pricey to replace.

Most of the time, the damage to your screen will be pretty obvious. You’ll see the spider web patterns of shattered glass across the front of your iPhone. Occasionally, however, the glass screen will be intact, and you might not realize the damage until you try to use it. Whether the damage is visible or not, it’s a good idea to run a quick diagnostic to determine the extent of it.

If you encounter any of these problems, you’re dealing with a broken LCD screen. If the glass is shattered, but the display is clear and touch capability is working, that’s a good sign. The problem is probably just the glass screen.

Whether you’re dealing with cracked glass or a broken LCD screen, you can find a quick, reliable repair service at FastPhoneRepair.com. Our qualified technicians will get your iPhone repaired and up and running again in record time and at reasonable rates.

LCDs are replaceable. They aren"t cheap, but it looks like a 1366x768 panel - it will be at the cheaper end of spectrum. I"m just eyeballing it though, so if you"re going to replace it yourself make sure to check its native resolution before replacement and make sure the new one is compatible.

As long as the edges around the screen aren’t dented and there are no bends to the display, an LCD panel replacement is all that is needed for a cracked screen repair.

MacBook Airs are great portable machines, but they are a little fragile when it comes to dropping or bending. I get numerous reports that the MacBook Air screens seem to break on their own during regular use, especially the newer M1 2020 MacBook Airs.

While most screen repairs do not require any difference in service, there are a couple of scenarios that come up once in a while with LCD-only replacements on MacBook Airs.

When something hits the MacBook Air screen from the back or very hard, sometimes the backlight sheets get damaged as well as the LCD. The backlight LED’s shine up from the bottom of the laptop and reflect off a white sheet of paper-like substance. There are additional sheets after this white sheet that diffuse the backlight and spread it evenly through the LCD panel.

Normally, we can just replace the LCD and any backlight issues are purely cosmetic. As you can see in the picture below, a damaged backlight usually causes white spots on the LCD. Normally this white spot is only where the impact point is.

So if the computer got hit from the back or front hard enough to damage the backlight, we can either replace the entire screen assembly for a possible additional fee or just replace the LCD and ignore the cosmetic white spot. If you want to read more about this issue, here is a White Spot On Backlight post on our blog.

I don’t get as many A1466 MacBook Airs as I used to, but I still get some! This model was one of the first ones Apple made with a pretty fragile screen. The newer 2020 M1 MacBook Airs seem to be even more fragile, but this redesign of the MacBook Air really did seem to …
