LCD meters are now widely used for several reasons:

First, LCD gauges have high clarity and visibility. LCD displays are able to present images with high clarity, high contrast, and bright colors, enabling drivers to read vehicle information, such as speed, RPM, fuel level, etc., more clearly, which improves the driver's visual experience.

Secondly, LCD gauges have lower energy consumption. Compared with traditional mechanical instruments, LCD instruments use electronic display technology, which can effectively reduce energy consumption and improve energy efficiency. This is very important for the energy saving and environmental protection requirements of modern vehicles.

In addition, LCD gauges also have a high degree of variability and personalization. LCD display can be flexible according to the demand for information display, different models and brands can be customized according to their own design needs to instrument display content and style, making the vehicle instrument more personalized, fashionable.

Finally, the LCD instrument also has fault diagnosis and automatic alarm function. Through the liquid crystal instrumentation can be real-time monitoring of the vehicle's working status of the various systems, once a failure or abnormalities, the liquid crystal instrumentation will automatically alarm and provide the appropriate prompts to help drivers take timely measures to ensure driving safety.

In summary, the LCD instrument has high definition, low energy consumption, variability and personalized customization capabilities and fault diagnosis and alarm functions and other advantages, and therefore is widely used in modern vehicles.

What does a dashboard do?

The instrument panel is a device that reflects the working conditions of each system of the vehicle, which mainly includes fuel indicators, washing fluid indicators, electronic throttle indicators, front and rear fog lights and alarm lights, which can monitor the status of the car at any time. The car dashboard is a device that reflects the working conditions of each system of the vehicle, and the conventional instruments of the general car include speed odometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging meter, etc. Car instrument is an important interface for information exchange between the driver and the car, with the development of automotive electronic technology, the amount of information about the driving conditions and institutions and parts increases significantly, and the driver is driving the vehicle, more, more timely understanding of whether the various parameters of the car and the engine are normal, in order to take timely measures to prevent accidents.

What are the common contents of the dashboard

1. Oil pressure gauge The oil pressure gauge is an instrument that shows the oil pressure in kPa (kilopascals). The oil pressure gauge sensor is a piezoresistive sensor that is threaded to the engine oil line. The oil pressure pushes the contact piece to move on the resistance, so that the resistance value changes and affects the amount of current passing through the meter to ground, driving the pointer to swing. Since the oil pressure has a certain pressure range, in order to be clear and clear, there are many cars with oil pressure gauges indicated by indicators, if the engine is still on when running, it means that the engine lubrication system may not be normal. 2. Water temperature gauge A water temperature gauge is an instrument that displays the temperature of cooling water in °C (degrees Celsius). Its sensor is a thermistor type sensor that is threaded to the engine cooling waterway. The thermistor determines the amount of current flowing through the windings of the water temperature gauge coil, which drives the meter pointer to swing. In the past, the cooling water of car engines was used as tap water, and many car engine cooling systems used special coolant, so it was also called coolant temperature gauge. 3. Fuel gauge The fuel gauge is an instrument that displays the amount of oil in the tank, the unit is L (liters), the pointer points to "F", indicating full oil, pointing to "E", indicating no oil; There are also 1/1, 1/2, 0 to indicate full oil, half tank of oil and no oil, respectively. There are two coils in the fuel gauge, one on the "F" and one side of "E", the sensor is a variable resistor controlled by the height of the float, and the change in resistance determines the strength of the magnetic field lines of the two coils, which determines the direction of deflection of the pointer. 4. Water temperature gauge and fuel gauge The water temperature gauge and fuel gauge are also indicated by indicator lights, the water temperature indicator is bright to indicate that the water temperature is high, and the fuel indicator light is bright to indicate that the fuel is near the low point, as an auxiliary reminder.

When a dashboard fails, how to troubleshoot it?

1. Stitch removal method When the reading of the automobile electrical instrument is abnormal, through analysis and inference, it may be that there is a tie fault in the wire inside the sensor or between the sensor and the indicator instrument, and the stitch removal method is often used for inspection. That is, by removing the wires on the relevant terminal posts, the cause and location of the fault are judged. Taking the electromagnetic fuel gauge as an example, when the internal iron or float of the sensor is damaged, and the wire between the sensor and the fuel gauge is ironed, no matter how much oil is in the fuel tank, after the ignition switch is turned on, the fuel gauge pointer always points to "0", and the wire removal method can be used to check. First, remove the wire on the sensor, if the fuel gauge pointer moves towards "I" at this time, the internal iron or float of the sensor is damaged; If the pointer still points to "0", remove the sensor terminal post wire on the fuel gauge, and if the meter pointer moves towards "I", tie the wire between the fuel gauge and the sensor; If the pointer is still not moving, it may be damage to the inside of the fuel gauge or an open circuit in its power cord. 2. Iron method When the reading of the automobile electrical instrument is abnormal, through analysis, it is inferred that the sensor iron may be poor or damaged, and the wire between the sensor and the indicator instrument has a circuit breaking fault, the iron tie method is often used for inspection. By connecting the relevant terminal posts with wires, the cause and location of the fault can be determined. After the ignition switch is turned on, the fuel gauge pointer points to "I" for the electromagnetic fuel gauge regardless of the amount of oil stored in the tank; For bimetal fuel gauges, the fuel gauge pointer points to "0", which indicates that the corresponding instrument sensor may have a bad iron, damage, or a broken wire between the sensor and the indicator instrument, at this time, the iron method can be used to check. First of all, connect the sensor to the terminal post with the wire, if the pointer turns, it means that the sensor is damaged or the tie is poor; If the pointer does not rotate, the wire can be used to tie the wire post of the indicator instrument to the sensor, if the pointer rotates, the wire between the sensor and the indicator instrument has an open circuit fault; If the pointer still does not turn, it indicates that the meter is internally damaged or its power cord is open. 3. Short connection method 在其它电器仪表工作均正常、只有与稳压器相连的仪表（如燃油表、电磁式水温表等）不工作时，可利用短接法进行检查。用导线将稳压器的输入、输出端短接，这时与稳压器相连的仪表指针若立即偏转，则为稳压器内部存在故障。
