3.5 Inch TFT LCD Display Module Touch Screen

TFT LCD (thin film transistor)TFT  is an active matrix liquid crystal display screen (AM-LCD) In one, set up a special light source in the TFT-LCD screen substrate can be back  "Active" controls all the separate pixels on the screen, which is called the active matrix TFT (active matrix TFT) The origin of this can greatly improve the display response time, the general TFT response time is faster, less than 80ms. And because TFT is the active matrix LCD, which allows the arrangement of the memory of the liquid crystal and will not recover immediately after the current has disappeared. TFT also improved the STN LCD The phenomenon of fuzzy flickering (water wave) effectively improves the ability to play dynamic pictures. and STN has an excellent color saturation, color restoration capability and higher contrast than TFT. The disadvantage is that the power consumption is relatively high and the production cost is relatively high. TFT LCD LCD screen LCD is the most mainstream display type, a large number of applications not only in MP3, MP4 products, products in the desktop LCD monitors, notebook computer, mobile phone, TV and so on is more common, I believe we must not strange.
