Compared with traditional instruments,

The popularity of energy vehicles has promoted the popularity of all-liquid crystal instruments. Judging from the Beijing Auto Show, many 12-inch full LCD instruments of new energy vehicles have come standard and are favored by consumers.

New energy vehicles no longer need to display the information of vehicle speed, water temperature and fuel quantity lights like traditional vehicles, but instead, they need the information of actual voltage, electric quantity and battery temperature. Traditional instruments have low precision, slow response, single display mode, rigidity and lack of scientific sense. All-LCD instruments can choose the traditional layout of the instrument style, highlight navigation, fuel consumption and other information, and even adapt and change according to the vehicle type and power mode, thus showing diversity and difference.

The full LCD instrument panel can not only display the basic information of vehicles such as vehicle speed, vehicle speed and fuel lamp, but also display navigation maps, multimedia and other functions, and even display information such as turbine pressure, throttle opening and braking force. Taking the electric quantity display as an example, the full LCD instrument can let users see the icon of the battery shape, and can also display the electric quantity change as a more detailed curve. For users, it can not only check the current information of the car, but also retrieve the historical information of the car, and also analyze and guide the driving habits of users, so that drivers can experience more driving pleasure.

The modeling of most full LCD instruments reflects the changeable effect through HMI rendering. Usually, an instrument will contain various thematic interfaces, and some OEMs will also associate the thematic interfaces with driving modes.

The full LCD instrument panel can meet the customized needs of users. As an ordinary driver, he mainly observes the driving speed, speed, fuel quantity, water temperature and tire pressure, while a car sports enthusiast, turbine, oil pressure, throttle opening and braking force are all very useful information. The full LCD dashboard has high flexibility in displaying information, allowing different users to choose their own information according to different needs.

Full LCD instrument panel has advantages in appearance, sense of science and technology and information display, but full LCD instrument also has many disadvantages. Sunlight is a big killer of LCD screen. Watching in sunlight will affect the effect, and the driver may not see the instrument clearly in the strong sunlight environment.

Secondly, the cost of full LCD screen is relatively high. Full LCD display, rich in information. Frequent interaction with the central control requires a very powerful chip and the LCD screen is expensive. Moreover, many instruments need to cut the LCD screen into various shapes, which increases the development cost.

The service life of full LCD is much shorter than that of mechanical instruments, and the indoor temperature in the car is high in summer, which is a great test for full LCD instruments. In harsh environment, full LCD is very easy to be damaged, and once there is a problem, the replacement cost will be high.

Due to the complexity of software design, the full LCD instrument may cause the dashboard to restart intermittently, during which the necessary vehicle information may not be displayed, which may pose a safety hazard.

On the whole, full LCD instrument is the general trend, and the demand has brought about the development of science and technology, but technology needs to be people-oriented. Many manufacturers have done a lot of cool and animated functions to attract consumers' attention, and at the same time, they should pay more attention to the safety and stability of the instrument. After all, cars are related to the personal safety of consumers and cannot be sloppy.
