It’s not uncommon to see black or purplish blobs on your broken device’s screen that look like ink (phone, tablet, or laptop). Is there, however, ink on your screen?
Because your screen’s pixels are dead or damaged, you see an ink stain or blob. More pixels are affected when pressure is applied to the damaged screen, spreading the “ink” across the screen.
Is There Ink in Your Screen?
No. This is how it goes. A screen lies beneath the glass of your broken device. Many different types of screens are used in devices, but LCD and OLED are the most common.
LCD is the abbreviation for liquid crystal display. A liquid crystal is a state of matter that exists somewhere between solid and liquid. This means it has properties that are similar to both liquids and solids.
Liquid crystal displays are made up of two glass or plastic panels with liquid crystals embedded in them. Because the liquid crystals do not produce the images you see on the screen, the LCD is referred to as a passive device.
The liquid crystals are illuminated by a backlight rather than emitting light themselves. Liquid crystals change the way light rays pass through them, resulting in different images and colors on the screen.
Organic Light-Emitting Diodes, or OLEDs, are a type of light-emitting diode. A light-emitting diode (LED) is a semiconductor device that serves as a light source and emits light when an electric current is passed through it.
When a current passes through the diode in an OLED, a thin film of an organic compound produces light. The OLED display consists of a flat glass or plastic panel with thin organic material films sandwiched between two conductors.
The OLED display, unlike LCDs, is referred to as an emissive display. This is due to the fact that it does not require a backlight and generates its own light.
The formation of pixels is something that all of these displays have in common.
A pixel is the tiniest square unit that makes up a display or screen’s image. The higher the resolution of a screen, the more pixels it contains.
A phone with a resolution of 1920×1080 pixels has a total of 2073600 pixels on the screen. When a pixel is damaged, it loses its ability to emit or alter light, and it becomes black or dark.
So, what’s the story behind the ink effect?
The ink-spreading phenomenon only occurs in LCD screens because the tubes that hold the liquid crystals break when the screen is damaged, allowing the liquid crystals to seep into the screen.
Each pixel in an OLED screen produces its own light and is unaffected by the actions of other pixels. As a result, if your screen is damaged, the pixels will die but will not spread like an ink stain.
While a phone with black spots or ‘ink’ can be managed for a while, it will eventually spread and damage more pixels. When you notice this type of damage, the best thing to do is replace the LCD screen. This is something you can do in the comfort of your own home.
