What is the difference between OLED LCD screen and TFT LCD screen

OLED relies on its own light emission to display images, without the need for a backlight source and not affected by surrounding light. Its lifespan is generally around 5000 times. TFT is an active matrix liquid crystal that requires the brightness of the backlight source to display images and is affected by surrounding light. Its lifespan is generally around 20000 times.

OLED LCD screen

OLED organic light-emitting display screens are fundamentally different from traditional LCD display methods in that they do not require a backlight source. They use very thin organic material coatings and glass substrates, which emit light when current passes through them.

Therefore, OLED LCD screens can be made lighter and thinner, with a larger viewing angle, and also more energy-efficient. However, it has a short lifespan and cannot make the screen larger. OLED is often used for foldable phone external screens.

TFT LCD screen

The abbreviation for TFT thin film transistor is currently the top-level material LCD screen, belonging to the active matrix type LCD screen. The back is equipped with special light tubes, which can "actively" control each independent pixel on the screen. This is commonly known as active matrix TFT, which has a relatively fast response time of about 80 milliseconds and a large viewing angle, usually reaching about 130 degrees. It is used in some high-end models. Due to the memory based arrangement of TFT LCD screens, they do not immediately return to their original state after the current disappears, effectively improving the ability to play dynamic images. The disadvantage is that it consumes a lot of electricity and the manufacturing cost is also relatively high.

OLED color screens are 30% more expensive than TFT color screens of the same size! The biggest difference between true color OLED screens and TFT screens is that OLED true color screens have a relatively high screen contrast and fuller color reproduction. In terms of backlighting and brightness, OLED true color screens are superior to TFT screens.
