A1: TFT LCD is a broader category that includes various sub-technologies, including IPS (In-Plane Switching). IPS is a specific type of TFT LCD that offers wider viewing angles and better color reproduction compared to older TN (Twisted Nematic) TFT LCD panels. IPS displays are known for their superior image quality but may have slightly slower response times compared to TN panels.
A2: Yes, TFT LCD displays can be suitable for gaming, especially those with high refresh rates and low response times. Many gaming monitors use TFT LCD technology, often with features like adaptive sync (e.g., FreeSync or G-Sync) to enhance the gaming experience. However, for the absolute best motion handling and contrast, some gamers prefer OLED displays.
A3: The lifespan of a TFT LCD display can vary depending on usage and quality, but they generally last between 30,000 to 60,000 hours of use. This translates to about 10 to 20 years for a display used 8 hours a day. However, the backlight may degrade faster than the LCD panel itself, potentially requiring replacement earlier.
A4: TFT LCD displays are generally resistant to permanent burn-in, unlike OLED screens. However, they can experience a temporary form of image retention, often called "image persistence." This is usually not permanent and can be resolved by turning off the display for a period or running screen-clearing patterns.
A5: In general, TFT LCD displays are less expensive than OLED displays, especially in larger sizes. For example, a 65-inch 4K TFT LCD TV is typically significantly cheaper than a 65-inch 4K OLED TV. However, the price gap is narrowing as OLED production becomes more efficient. The exact price difference can vary based on brand, features, and current market conditions.
