Which is better, TFT display screen or WQVGA screen? 10

Judging by the name, the latter is good. Generally, cheap male models *** use the former, because of its low resolution, that is, you will look rough. The latter has a high resolution and a very detailed picture. In fact, the visual effect is more or less related to the size of the screen.

TFT (Thin Film Transistor) is a thin film field-effect transistor, which can "actively" control each individual pixel on the screen, which can greatly improve the reaction time. Generally, the response time of TFT is relatively fast, about 80 milliseconds, and the viewing angle is large, generally about 130 degrees, which is mainly used in high-end products. In this way, it can display screen information with high speed, high brightness and high contrast.

TFT belongs to the active matrix liquid crystal display, which is technically driven by the way of "active matrix", which is driven by the use of transistor electrodes made of thin film technology, and the use of scanning method "active pull" to control the opening and closing of any display point, when the light source is irradiated, it is transmitted upward through the lower polarizer, and the light is conducted with the help of liquid crystal molecules, and the purpose of display is achieved through shading and light transmission.

Many of the new generation of color screen mobile phones support 65536 color display, and some even support 160,000 color display, at this time, TFT's high contrast and rich color advantages are very important.

The main components of TFT-type liquid crystal display include: fluorescent tube, light guide plate, polarizer plate, light filter plate, glass substrate, alignment film, liquid crystal material, thin mode transistor, etc.

How about the TFT screen

TFT also improves the phenomenon that STN will flicker (water ripple) blur, effectively improving the ability of ** dynamic pictures. Compared with STN, TFT has excellent color saturation, reduction ability and higher contrast, but the disadvantage is that it consumes more power and the cost is higher.

TFT liquid crystal is equipped with a semiconductor switch for each pixel, each pixel can be directly controlled by point pulse, so each node is relatively independent, and can be continuously controlled, not only to improve the response speed of the display screen, but also to accurately control the display color level, so TFT liquid crystal. The colors are more realistic. TFT LCD display is characterized by good brightness, high contrast, strong sense of hierarchy and bright colors, but it also has the shortcomings of high power consumption and high cost.

TFT LCD technology has accelerated the development of mobile phone color screens. Many of the new generation of color screen mobile phones support 65536 color display, and some even support 160,000 color display, at this time, TFT's high contrast and rich color advantages are very important.

AMOLED, TFT is the screen material. QVGA, WQVGA is the resolution of the screen. (QVGA is 240*320 resolution; WQVGA is 400*240 resolution).

AMOLED is known as the next generation of display technology, in terms of display performance, AMOLED has a faster response speed, higher contrast, and a wider viewing angle, which is that AMOLED is inherently better than TFT

place of LCD; In addition, AMOLED has the characteristics of self-illumination and does not need to use a backlight board, so it can be made thinner and lighter than TFT, and it is more power-efficient; One more important feature is that there is no need to use a backlight panel.

AMOLED can save TFT

LCD3 4 is the specific gravity of the backlight module cost.

Simply speaking, AMOLED is better than TFT.

First of all, IPS is not a screen material, but the name of a technology, its essence is actually Super TFT, that is to say, in fact, IPS screen is also a kind of TFT screen!

If you want to say which one is better, of course, the screen with IPS technology is good. The IPS screen has changed the arrangement of TFT liquid crystal molecules (the liquid crystal molecules of ordinary TFT are arranged horizontally, while the liquid crystal molecules of IPS are arranged vertically), so that it has a larger viewing angle, and there will be no obvious water ripples when pressing the surface of the screen (that is, the so-called hard screen), the color reproduction is better, and the picture is more realistic, which are incomparable to ordinary TFT.

With so many advantages, it also brings an increase in cost, which will be higher than that of ordinary TFT panels.
