- OLED (Organic Light Emitting Diode): A newer technology that generates light directly from organic compounds, offering superior color and contrast.
- Plasma: Older technology that utilizes gas cells to create images, known for rich color and deep blacks.
Different technologies have unique characteristics, but each can fall victim to the problem of bubbling. Understanding how these technologies work sets the stage for uncovering what causes bubbles on your TV screen.
What Causes Bubbles on a TV Screen?
Bubbles on your TV screen can manifest in several forms and may arise from various sources. Let’s explore the common causes of these frustration-inducing anomalies.
1. Manufacturing Defects
Manufacturing defects can lead to bubbles forming during the production process. These defects may be due to:
a. Poor Adhesion
During the assembly of an LCD or OLED screen, layers including the liquid crystal layer and the protective glass must adhere properly to prevent bubbles. If the adhesive process is flawed, it can result in air pockets forming between the layers.
b. Quality Control Issues
Some televisions may escape rigorous quality control checks, leading to screens with defects. Inferior materials and poorly executed assembly processes increase the likelihood of issues such as bubbling.
2. Environmental Factors
Environmental conditions also play a significant role in bubble formation on your TV screen. Factors to consider include:
