Understanding TV Display Technology
Before diving into the reasons behind a dark section of your TV screen, it’s crucial to understand how modern televisions operate. TVs today typically utilize one of two primary display technologies: LCD (Liquid Crystal Display) and OLED (Organic Light Emitting Diode). Each technology has its strengths and vulnerabilities.
LCD Technology
LCD TVs use a backlight to illuminate the liquid crystals that form the image on the screen. This backlight can be either full-array, edge-lit, or direct-lit. When an issue arises, it often manifests as uneven lighting on the screen.
Common Problems in LCD Displays
Uneven Backlighting: This occurs when certain sections of the LED backlighting system fail. If the LEDs on the right side are not functioning optimally, that could explain the darker area.
Panel Damage: Physical damage to the screen can also result in dark spots. This includes cracks or pressure that disrupt the ability of the liquid crystals to respond properly.
OLED Technology
Unlike LCDs, OLED TVs emit light on a pixel-by-pixel basis. While this leads to superior contrast and vibrant colors, it introduces its own issues.
Common Problems in OLED Displays
Pixel Failure: If an individual pixel or a cluster of pixels on the right side has malfunctioned, it may not emit light, resulting in a dark area on the screen.
Burn-In Issues: Prolonged display of static images can lead to burn-in, where ghost images cause parts of the screen to appear darker.
