What are the main types of TV panels available today?
The main types of TV panels available today are LCD, LED, OLED, and QLED. LCD (Liquid Crystal Display) panels are the most common and use a backlight to illuminate the liquid crystals, creating the image. LED (Light Emitting Diode) TV is a type of LCD that uses LEDs for backlighting, offering improved brightness and color range compared to traditional LCDs.
OLED (Organic Light Emitting Diode) panels are unique because they use organic compounds that emit light when an electric current passes through them. This allows for deeper blacks and better contrast ratios since each pixel can be turned on or off independently. QLED (Quantum Dot LED) panels, developed by Samsung, use quantum dots to enhance color and brightness, providing vibrant color accuracy while still using an LED backlight.
What is the difference between OLED and QLED panels?
OLED and QLED panels have fundamental differences in how they produce images. OLED panels generate their light from organic materials at the pixel level, meaning they can achieve perfect black levels and infinite contrast. This is due to their ability to completely turn off individual pixels, resulting in an impressive viewing experience, particularly in dark environments.
On the other hand, QLED panels use a backlight combined with quantum dot technology to enhance brightness and color. While QLEDs can achieve higher brightness levels than OLEDs, they do not reach the same level of black depth and contrast because their pixels cannot turn off independently. Consequently, QLED displays shine in brightly lit rooms, making them a popular choice for well-lit spaces.
What does the term ‘panel refresh rate’ mean?
Panel refresh rate refers to the number of times per second a TV can refresh the image on the screen, measured in hertz (Hz).
