TFT display screen with QVGA What's the difference?

To thank the

QVGA that Q is the Quarter, QVGA is to say its name implies is one of the 4 minutes of VGA size.Is in the liquid crystal screen On the output resolution is 240 × 320 pixels.It should be noted that some media as a QVGA screen with the TFD, such as LCD and TFT materials of the same things wrong, QVGA screen with the more common view of Japan's mobile phone number, the current Microsoft's smartphone operating system PPC screens are also 320 × 240 pixel QVGA screen.

TFT (Thin film Transistor, thin-film transistor) screens, it is also present in high-end color is commonly used in cell phone screen, 65,536 hours and 260,000-color color, the color of the three 16,000,000, which show excellent results.

So-called QVGA LCD technology, is in the output of liquid crystal screen resolution is 240 × 320 LCD output.This In fact, resolution and screen size is no relationship between them.For example, if 2.1 inches LCD screen can display 240 × 320 resolution images, that is called “QVGA 2.1-inch LCD screen”; if 3.8 inches LCD screen can be 240 × 320 display the image, that is called “QVGA 3.8-inch LCD screen,” although both cases have the same resolution, but the actual size of the different visual effects are also different, generally speaking, a small-screen images Naturally smaller.

TFT (Thin Film Transistor, thin film field-effect transistor), LCD is the last point of each liquid crystal pixel are then integrated into the thin-film transistor to drive.In order to Can do high-speed high-brightness high-contrast display screen of information.TFT active-matrix liquid crystal display belong to, is the best color LCD displays, close to the effect of CRT monitors, notebook computers and is now on the mainstream desktop display Equipment.TFT for each pixel are integrated in the TFT on its own to control, is active pixels.As a result, not only can greatly improve the speed and brightness and contrast ratio also increased significantly, while also reaching resolution A very high level.

I have said very clearly:”TFT active-matrix liquid crystal display belong to, is the best color LCD displays, CRT monitors close to the effect”.
