What is trumotion 120 of LG TV?

what does LG TV trumotion 120 mean anyway？

Actually, it refers to the refresh rate.

The refresh rate is expressed in Hz, indicating the number of times the display refreshes per second. 120Hz refers to the number of times the display refreshes per second. It is used to measure the update speed of the mobile phone's display. However, the high refresh rate of the screen can increase procurement costs, and the CPU chip and battery power requirements are significant.

LG TV lists TruMotion data and the native refresh rate of the display panel in the form of "TruMotion 240 (refresh rate 120Hz)" or "TruMotion 120 (native 60Hz)"

120Hz technology, in fact, is a technology for double frequency frame insertion of TV image signals, that is, the original 50-60Hz field frequency is changed to 120Hz.

The screen to achieve a high refresh rate, in fact, mainly depends on the update of the driving material. Early LCD screens were driven by amorphous silicon, a material that was large but not powerful, which could be interpreted as requiring more per unit volume to drive a single liquid crystal molecule. Therefore, high refresh rates cannot be achieved.

Now the drive material has been upgraded. For example, most OLED displays use LTPS (low-temperature polysilicon) technology. Now more powerful LTPO technologies are available. Low-Temperature Polycrystalline Oxide, boasts higher charge mobility and faster pixel reaction than LTPS (Low-Temperature Polycrystalline silicon thin Film transistor) technology.
