Line out is also provided for connectivity to a external amplifier, It is possible to provide greater output power! Scope of application & Ports. More possibilities for your needs! TFT (Thin Film Transistor) is a thin film field effect transistor, which is a kind of active matrix liquid crystal display. TFT liquid crystal display is characterized by good brightness, high contrast, strong sense of hierarchy, and bright colors, but it also has the disadvantages of relatively power consumption and high cost. For example, the famous JDI screen belongs to the TFT-LCD display screen, which adopts the LTPS low temperature polysilicon technology screen. Compared with traditional LCD screens, JDI screens are thinner and more transparent. A TFT screen with 160,000 colors. The display effect of a TFT-type display is closest to that of a CRT-type display. TFT-type screens also often appear on the screens of major mobile phones, with 65,536 colors, 160,000 colors, and 16 million colors, respectively. The display effect is also very good. Our TFT screen color has 160,000 colors, you can enjoy a better viewing experience. More about TFT screens. The new machine GS-301 uses the latest TFT LCD screen technology (not the conventional LCD liquid crystal screen), allowing you to have a better viewing experience visually. Maybe you have doubts. What is the difference between TFT LCD screens? Why is it more expensive?? Advantages of TFT LCD screen. TFT is equipped with a special light pipe on the back of the liquid crystal, which can “actively” control each independent pixel on the screen, which is The origin of the so-called active matrix TFT (active matrix TFT), which can greatly improve the response time. Generally, the response time of TFT is relatively fast, about 80ms, while that of STN is 200ms. If you want to increase it, flickering will occur. And because TFT is an active matrix LCD, the arrangement of liquid crystals can be memorized, and it will not return to its original state immediately after the current disappears. TFT also improves the phenomenon of STN flickering (water ripple)-fuzzy, effectively improving the ability to play dynamic pictures. Compared with STN, TFT has excellent color saturation, restoration ability and higher contrast, but the disadvantage is that it consumes more power and costs more. Summarize the characteristics of TFT screen. It can display screen information with high speed, high brightness and high contrast.
