Consumer smartphones when the choose and buy, can consciously know about the screen, screen, after all, good or bad directly affect the experience.
Look at the screen, which involves use of display materials, such as TFT, IPS (
, SLCD, Super AMOLED, etc, among which the manufacturer is the most used TFT and IPS screen.
In particular, the IPS screen known as Super TFT, is to use the TFT IPS technology.
< / p> then in TFT and IPS which screen is better?
Here is for everyone to do a simple introduction, and teach you some basic methods of resolution.
< / p> TFT LCD screen < / p> TFT LCD screen brightness is good, high contrast, administrative levels clear, color is more bright.
Defect is more power, the cost is relatively high.
Composition of type TFT LCD is mainly include: fluorescent tube, guide plate, polarizing film, filter plate, glass, match to the film, liquid crystal materials, thin model transistor and so on.
But what is its structure?
Shenzhen jing yao LCD module
manufacturer share structure of TFT LCD screen: < / p> TFT LCD composed of multilayer superposition, just like the sandwich.
The outermost layers of the two sides is high transparency of the glass layer, in the middle of the glass layer is thin film capacitors, necessary to produce red, blue, green color color filters, and liquid crystal layer.
Have a jade-like stone light back illuminant irradiation from behind the screen power, complete LCD display.
< / p> usually, without charge, liquid crystal in a state of disorder.
In this state, the LCD is pervious to light, the liquid crystal layer in different charge, liquid crystal crystal of deflection in different direction, the liquid crystal layer to form different pervious to light quality.
As the traditional CRT display, red, green, blue three color liquid crystal mixture, forming a pixel.
Control red, green, blue three color point voltage, make different concentrations of three color mixing, is needed for the formation of a variety of colors.
The TFT screen of monitor power is made up of one division division pixels, the first control point has a transistor.
Resolution is formed by these points, if a liquid crystal display resolution is 1024 * 768 pixels (
, then it's really there are so many points.
< / p> < / p> < / p> IPS screen is introduced: < / p> IPS screen name is (

Plane Switching, Plane transformation)
IPS technology has changed the arrangement of particles, the liquid crystal molecules using level conversion technology, speed up the deflection of the liquid crystal molecules, guarantee in the shaking screen resolution can also have a strong expressive force, eliminates the traditional liquid crystal display when receiving outside pressure and shaking with fuzzy and water lines spreading phenomenon.
Due to the liquid crystal molecules rotate in the plane, so the IPS screen is inherently has a good visual Angle, can do four axial line close to the Angle of 180 degrees.
< / p> although IPS screen technology is very severe, but it is a technology based on TFT, nature or TFT screen.
Regardless of the IPS to what extent, is based on the TFT derivative products, after all.
< / p> by shenzhen jing yao LCD module manufacturer small make up this article, good for TFT LCD screen or IPS screen good, the in the mind have a the answer?
