What is LCD Bruising?
LCD bruising, popularly known as “screen discoloration,” is one of the simplest problems any electronic device can have, especially those that come with an LCD (Liquid Crystal Display) screen. These appear in the form of abnormal patterns or colors on the screen or as dark shadows which might interfere with the viewing experience and possibly indicate internal damage. Knowing what causes the bruising, how to fix screen discoloration, and how to prevent it in the first place are all ways to ensure that the LCD is kept in great shape. In this article, we will look at the various means used for these purposes and give a detailed look into LCD bruising and how best it can be addressed.
Causes of LCD Bruising
LCD bruising typically results from:
- Physical Damage: This is one of the most frequent reasons when screens turn out to be discolored. Thus, by dropping the device or by pressuring it too much on its screen, it does bruise. The bruising then is seen as dark spots or discoloration on the display.
- Manufacturing Defects: Sometimes, bruising among LCDs may emanate from defects at the point of manufacture. Poor quality control can cause uneven distribution of liquid crystals, hence leaving spots of discoloration.
- Heat Exposure: Similarly, high temperatures for a long time also affect the LCD panel, causing discoloration. This is more relevant to devices left in hot environments such as inside a car on a sunny day.
- Aging Components: LCD screens are made up of material that degrades over time and may eventually cause discolorations. This may be evident with older devices where crystals perhaps no longer serve perfectly.
- Water/ High Humidity Damage: If an LCD display is exposed to water or high humidity, it may also show discoloration caused by malfunctioning of internal components of the LCD. This is a pretty big issue for those devices intended not to be water-resistant.
- Other causes are electrical, such as faulty wiring or electrical surges, which may cause damage to the LCD. Inconsistent power supply promoting irregular screen action can further cause discoloration.
How to Fix LCD Bruising
Fixing LCD bruising can vary depending on the severity of the damage. Some ways to fix LCD bruising are as follows:
- Soft Reset: Sometimes, minor display issues may come right with just a simple soft reset. Switch the device completely off, wait for a couple of seconds, and power it back on. This will sometimes reboot the screen.
- Adjust the Display Settings: First of all, check the display settings on your computer. By adjusting the brightness, contrast, and color settings, it may reduce the bruising effect. Sometimes, slight adjustments may help in overall screen appearance.
- Screen Calibration: Most devices have built-in calibration utilities that can be used for improving the display settings. Utilize these utilities and attempt recalibrating the screen, which might reduce discoloration.
- Professional Repair: If there is extensive bruising, or if it lingers a bit longer, then a visit to the professionals for repairs just might be necessary. The technicians take a look at the damages and choose whether the replacement of the LCD panel is required. This is mainly the best option if there is considerable discoloration.
- DIY Repair Kits: Those of a more technical inclination may buy a do-it-yourself kit with the necessary tools and instructions to replace the LCD screen themselves. However, this is best attempted by those who have experience with fixing electronic devices, as this might invalidate their warranty and can easily cause more damage.
- Screen Protector Usage: Attach a good-quality screen protector to prevent further damage to the LCD. Of course, this cannot heal the bruising but can save it from future impacts and scratches.
- Cleaning Routine: Keeping the device clean and clear of dust and debris helps in sustaining the quality of the screen. Regularly inspect the device for signs and damage that could be preventing the device from operating properly, and address them as soon as possible.
Preventing LCD Bruising and Discoloration
To prevent damage to your LCD screen:
- Use Protective Cases: A hard protective case should go a long way in absorbing shocks and preventing damage. Cases with strengthened edges and corners provide greater protection.
- Avoid extreme temperatures: Temperatures from very hot to very cold can affect all electronic devices. Do not leave in extremely hot vehicles or in direct sun for a very long period of time.
- Handle with care: Devices are fragile, so be gentle when handling them; do not put heavy objects on top of them, and think about the practicality of how they will be stored.
- Cleaning regularly: Clean the screen regularly using appropriate cleaning solutions and microfiber clothes. This keeps it clear and also prevents any scratches that can further cause bruising.
- Limiting exposure to moisture: If your device is not water-resistant, then don’t use it in highly humid areas or even near water sources. Perhaps you may store devices using moisture-absorbing packets.
- Electrical Safety: Use surge protectors so they can protect the device from surges in electricity. This can aid in preventing damage to internal components of your device, such as the LCD.
- Inform Users: In case the device has multiple users, educate them all in proper handling to minimize the risk of damage.
Conclusion
LCD bruising is a common problem that tries to affect functionality and aesthetic view in general. Causes vary, and understanding them, ways in which screen discoloration can be fixed, and how to prevent it, go a long way in users taking up measures in protecting gadgets. LCD bruising is best addressed through careful handling, regular maintenance, or professional repair to ensure the longevity and functionality of electronic screens.
FAQs About LCD Bruising
Is LCD bruising repairable?
Yes, depending on the severity of bruising. It may disappear after soft resets or minor settings changes; for serious bruising, it can only be repaired professionally by replacing the LCD panel.
How do I know if my screen is bruised or simply dirty?
Try a simple test: clean the screen. If there is remaining discoloration after cleaning, it may be bruising. Moreover, bruising typically will appear as dark spots or shadows while the dirt will appear highly uniform.
Can one use a device with a bruised LCD?
It may be safe to have slight bruising and have continued use with the device since major discoloration could mean serious damage underneath that may get worse with time. Have it repaired if the bruising affects your use of it.
What if my device is still in warranty?
If it is in warranty, contact the customer service representative of the manufacturer or retailer. You yourself need not attempt any repair because that can nullify the warranty of the device.
Can LCD bruising occur in any device?
Yes, LCD bruising may be caused in all devices that have an LCD screen. In addition to smartphones and tablets, it also includes laptops and even televisions.
How long does it take for an LCD screen bruise to fade?
Unlike physical bruises of the skin, LCD bruising doesn’t fade out with time. When discoloration takes place, an intervention is usually necessary to get rid of it.
