A green line on your mobile screen, whether in a horizontal or vertical position is usually annoying and worrying at the same time. Even if it is a serious issue, knowing the underlying reason will help you choose the best course of action. Typically, a green line refers to a hardware problem, which may involve the display. However, before having the hardware rectified, you can attempt a few things under the software area.
In this informative guide, we will discuss the various ways of fixing the green line issue on mobile phones. But before enlisting the troubleshooting tips, let’s understand the possible causes for the vertical green line and horizontal green line issues on mobile screens.
What are the Reasons for Vertical and Horizontal Green Lines on Mobile Screens?
Vertical or horizontal green lines on a mobile screen are typically caused by issues related to the display hardware or software, with some common reasons as follows:
1. Defective Display Panel
Like any other electronic display technologies, both OLED and LCD screens of mobile phones can experience problems that are due to age, or that are inherent in the manufacturing process. It may seem that green lines show up on the screen if the pixels or subpixels, which form the image, get damaged or do not receive correct signals.
2. Loose or Damaged Connector
In a mobile device, the screen is connected to the motherboard and flex cable is also required in its production. This connector should be tight and properly placed inside its housing because, if not, it will break the signal flow and cause green lines. It is also possible to disconnect these connections by dropping or bending the phone.
3. Water or Moisture Damage
Water in particular should not come in contact with the display since it leads to corrosion or short circuit in the parts. This can disrupt the quality of the colors displayed on the screen and such things as vertical or horizontal lines may appear.
4. Physical Impact or Pressure Harm
Applying pressure such as sitting on it or dropping the phone will in one or the other, harm either the screen layers or the internal elements. Some of this physical damage may interfere with the electrical connections and this will cause lines to appear on the display.
5. Software Glitch
Some problems that are connected with displays are of a software nature. This is usually caused by a system glitch or by a conflict with another app that is run on the mobile, or after a system update.
6. Overheating of the Device
Excessive heating due to usage or abuse, intensive application, or environmental conditions, can exert a certain load on the display elements. Long-term operation of a mobile phone under high ambient temperatures may result in the formation of lines that may be permanent or only evident when the components are strained.
7. Aging or Wear and Tear
This could be due to the old age of the screen, meaning that a new part has to be affixed to fix a device. The Aging of the display may cause failure of pixel rows or columns and this may be presented by green lines on the screen.
8. Graphic Processing Unit (GPU)
Green lines can also appear if a gadget is incapable of handling graphics well, and green lines are often associated with failing GPU or some problems with the display drivers. This is not very typical but can be noticed in old-build gadgets or those that have a problem with the graphic processing unit.
