What is the difference between tft and oled

TFT technology has been in production for several years and is here to stay. There are several TFT glass suppliers to support current demand and they have a great deal of capacity for increased demand. Toggle menu Login or Sign Up 0.

The organic compound film is typically situated between two electrodes, one of which is transparent. OLEDs are mostly used in smartphones and limited releases of high-end smart televisions. It can also be used in computer monitors and handheld game consoles. Meanwhile, LCDs need backlights because the liquid crystals cannot create light on their own. OLED wins in the black levels feature. LCDs are also prone to blooming, where a bright part spoils the darkness of an adjacent black area.

This is because LCDs inherently block light due to their filtering layers, and that creates added depth which makes LCD viewing angles limited. Energy consumption in OLED displays depends on the screen brightness. Less brightness used means lower power consumption, but this may not be ideal because the contrast ratio will suffer when brightness is reduced. Meanwhile, the backlights form the bulk of power consumption in TFT displays.

Putting the backlight to a lower setting significantly improves the energy efficiency of TFT displays. Both character and graphic LCD displays use only a moderate amount of electricity and take up only a moderate amount of space, and are therefore very suited to mobile applications on batteries. In TFT displays every pixel is directed by a tiny semiconductor that controls the amount of light that is allowed to pass through, which results in better resolution, contrast, and speed.

With OLED displays a major step has been taken thanks to their very clear resolution, high contrast, wide viewing angle, and significantly lower power consumption. Finally, e-Paper displays provide the ideal solution for applications such as e-readers, interactive billboards, and interactive price tags in supermarkets, for which power consumption is critical and the display must remain static for a long period of time.
