Most modern vehicles now use large LCD screen. It looks more beautiful, concise, and cool. But it is not easy to disassemble the cluster when calibrating the mileage of the instrument.
The instrument has an LCD display that is easily damaged and has a high risk of damage. But now most LCD instrument models are used as display screens, which do not contain storage chips,
the CPU processors are stored in the radio module or even body control units. For example, on some Great Wall and BYD vehicles.
