The smartphone screen is the most frequently used component and also the most vulnerable to damage. One common issue faced by many users is the appearance of lines on the LCD, whether horizontal or vertical. This problem not only disrupts visual clarity but can also affect touch sensitivity. If left unchecked, the damage will usually worsen until the screen goes completely blank.
To avoid this, here are some detailed tips to keep your LCD in good condition and prevent screen lines.
1. Use High-Quality Screen Protectors & Cases
Many users only focus on protecting the phone body, when in fact even minor impacts can damage the LCD panel. Using a durable phone case along with a tempered glass protector helps absorb shocks and prevent cracks. A quality screen protector can also minimize scratches that may gradually affect display clarity.
2. Avoid Excessive Pressure on the Screen
Pressing the screen too hard while typing or gaming can damage the LCD’s inner layers. Remember, smartphone screens are designed to respond to light touches. If you use a stylus, choose one that is compatible and designed for mobile screens to avoid unnecessary pressure.
3. Don’t Store Phones in Tight Pockets or Under Pillows
Keeping your phone in tight jeans pockets or placing it under your pillow while sleeping applies constant pressure on the screen. Over time, this pressure often leads to LCD lines. Instead, place your smartphone on a safe, flat surface to reduce the risk of damage.
4. Use Original or Certified Chargers
Another often-overlooked cause of LCD damage is using cheap or uncertified chargers. Unstable electrical currents can harm internal components, including the LCD flex cable. Prolonged use of counterfeit adapters or cables can permanently damage the screen.
5. Avoid Excessive Heat Exposure
Smartphones that overheat from long gaming sessions or streaming can wear out screen components faster. High temperatures can weaken the LCD flex connections and cause screen lines. Take breaks during heavy use to prevent overheating.
6. Repair Immediately if Lines Appear
If you notice thin lines starting to show on the screen, don’t delay repairs. Small lines are usually the early warning signs of LCD damage, which will spread over time. Taking your phone to an experienced technician and using original spare parts is the best way to avoid total screen failure.
Keeping your smartphone screen healthy requires the right habits — from proper protection, safe storage, to using the correct accessories.
