Modern owners of equipment, in particular smartphones, very often have a problem in the form of white or yellow spots appearing on the display of the gadget. This problem is particularly relevant among people who own inexpensive phones. As the statistics show, similar traces on the smartphone screen can appear already in half a year, after the acquisition of the smartphone. Most are interested in the question: how to remove the yellow spot from the display of your favorite mobile phone? In order to eliminate this problem, it is necessary to determine the cause of its occurrence. Let's do it together.
Causes of yellow spots on the smartphone display
Experts are convinced that there are only a few factors that can provoke such problems. We will deal with each separately.
Moisture
Moisture is one of the most popular causes of yellow and white spots or streaks under the display of a smartphone. The backlight of the LCD screen includes light bulbs, several films and an inverter.LEDs direct their light to the side of the phone, and the films distribute it across the screen, creating a uniform glow. If there is water between the layers of the film, they begin to stick together, because of this the light is distorted and a noticeable trace appears in the form of a spot. This problem does not apply to phones with AMOLED-displays, since there is a completely different structure and a drop of water will not create visible problems.
Important! In the case of moisture under the screen spot has an irregular shape and is characterized by high brightness. Changing the viewing angle you can see that the spot changes its shape or becomes completely invisible.
LED backlight problems
Another reason for the appearance of yellow spots on the smartphone screen is the failure of the LEDs. If at least one of them is not functioning, then a small but noticeable yellow spot will appear on the display of the gadget.
Overheating
Also, the cause of unpleasant stains in the form of stains may be overheating of the phone, which is possible in cases where the manufacturer did not install a heat sink or made a mistake during its installation. The area where the temperature exceeds the permissible, the films will begin to deform (change shape). After cooling, stains may appear, which are not so easy to remove.
Important! The spots on the smartphone screen from overheating have a yellow color, their hue depends on which part of the screen the stain is. For example, at the edges of the screen spots will be lighter, but in the center the opposite. However, all the spots caused by overheating gradually darken, becoming dark yellow.
Manufacturing defects
No less relevant is the problem with yellow spots, resulting from poor-quality assembly equipment. The effect is similar to what appears from the ingress of water under the display. Such a result in the form of spots is possible if the master mistakenly chose the length of the screws. They, pressing against the films, squeeze them with each other, as a result of which the screen shows round yellow spots, the shape of which from the viewing angle remains unchanged. If it is established that the problem is in this, then it is better to replace the smartphone by buying better and more expensive equipment.
Battery swell
The final problem that can be encountered is battery swelling. The battery is of great importance for a tablet or smartphone, so in case of swelling, the battery must be urgently removed and replaced with a new one.
Important! Repairing the backlight is an expensive and painstaking process, so most experts advise you not to risk it, but to change the screen module.
