Speed, speed, water temperature, and fuel volume are the most common display methods for ordinary pointer instrument panels. A small LCD screen is also added to the instrument panel of some models, which can display at most the gear position, tire pressure, Supplementary information such as fuel consumption. The full LCD instrument panel can not only display this information, but also display navigation maps, multimedia and other functions. If the manufacturer is willing, even information such as turbo pressure, throttle opening, and braking force can be displayed. It is not an exaggeration to say that it is a computer display that controls the entire vehicle's information system.

At the same time, the LCD instrument brings us an intelligent experience. Many cars now have functions such as mobile phone interconnection and Bluetooth answering calls. The dashboard can display some mobile phone interconnection functions to prevent drivers from looking for information on their phones everywhere. , Making calls is also more convenient. These are intelligent services that mechanical dashboards cannot provide. For drivers, they definitely like this mode of operation that is simple and does not affect safe driving.

The information it displays is very comprehensive. The full LCD dashboard is not like a traditional mechanical dashboard. The data of a mechanical dashboard is generally customized position data. Other information can only be displayed on a small-screen driving computer. The LCD instrument panel is much richer than it. In addition to displaying some conventional data, it can also display weather, road conditions, navigation, etc.

Some models are actually inseparable from the full LCD instrument. For example, electric vehicles with completely different power sources do not need to display information such as speed, water temperature and fuel quantity; instead, they need more accurate display of information such as voltage, power, and battery temperature. The full LCD instrument can even retrieve the historical information of the car. , Analyze and guide users' driving habits. However, traditional pointer instruments have the disadvantages of slow response, low accuracy and single display mode, and they are no longer capable of meeting the requirements of automobile electric and intelligent.

Today's mechanical instruments and full-liquid crystal instruments are just like the quartz watches and mechanical watches of the year. The later-born quartz watches are obviously more accurate, lighter and thinner, and cheaper and cheaper. However, the mechanical watch was not abandoned by the market because of the appearance of the quartz watch. It actively abandoned its uncompetitive low-end market and turned to the high-end. Conquered consumers with the beauty of its own machinery and craftsmanship, and is still loved by people all over the world. When the quartz watch first appeared, the price was significantly higher than that of the mechanical watch. Later, due to the maturity of technology and the market's approval cost, the price of the quartz watch has been far lower than that of the mechanical watch. I think the fate of mechanical instruments and full LCD instruments is the same. In the future, LCD instruments will definitely become more and more popular, and most cars will adopt them. The mechanical instrumentation will move to the high-end market and will only appear in luxury cars.
