These are three different types of problems in the liquid crystal field.

Let me talk about TFT first: TFT refers to TFT (Thin Film Transistor), which refers to thin film transistors,

which means that each liquid crystal pixel is driven by a thin film transistor integrated behind the pixel.TFT is currently a kind of active drive.
Correspondingly, the black display was passively driven very early.Now basically the higher resolution TFT-LCDs are used.

Let’s talk about LED backlighting. Since the liquid crystal display is a non-active display technology, that is to say, the liquid crystal panel is just a light switch, which controls the switch of each pixel to display the image.Then a surface light source is needed behind this light switch to emit light.This surface light source is called backlight.There are generally two types of backlight sources, one is FCCL (cold cathode tube) and LED (light emitting diode). The LED backlight means that the light source is LED.

IPS is a full-view technology, originally patented by Hitachi, and now both LG and Chi Mei have obtained patent authorization.Relatively speaking, the direction of the liquid crystal arrangement in the panel is different.So as to achieve the effect of expanding the viewing angle.That is, from a wider angle of view facing the left, right, up and down of the display device, the effect of the display does not change much.IPS technology has obvious advantages:If the viewing angle is wider, there is no obvious color change when pressing the screen, but at the same time it will also lead to an increase in energy consumption (decrease in transmittance).As a TV, it has advantages, but as a mobile phone, computer, IPS has no advantage.

Since these three are technologies of different aspects of liquid crystal display devices, they can coexist.For more information on touch screen and display screen, please contact our professional. salesperson
