The flashing or strobe effect can sometimes be related to the inherent characteristics of these technologies or how they are implemented in your TV.
Display Technologies and Flicker
- LED TVs often use a backlight to illuminate the liquid crystals that block or allow light to pass through to create images. The backlight can sometimes cause a flicker, especially if it’s not properly synchronized with the content being displayed.
- OLED (Organic Light-Emitting Diode) TVs produce their own light and do not require a backlight. However, they can still exhibit a form of flicker due to the way pixels are driven or due to certain features like PWM (Pulse Width Modulation) dimming.
- QLED (Quantum Dot Light Emitting Diode) TVs combine the benefits of LED TVs with quantum dots to enhance color accuracy and brightness. Like LED TVs, they can be susceptible to backlight flicker.
Content and Viewing Environment
The content you’re watching and the environment in which you’re viewing it can also play a significant role in the perceived strobe effect. For instance, certain types of content, especially those with high frame rates or specific lighting effects, can exacerbate the flicker. Additionally, the lighting in the room, the position of the TV, and even the type of power supply can influence the performance of your TV.
