reflected car dashboards operating condition of each device is a vehicle system. Usually by the speedometer, tachometer, oil pressure gauge, water temperature, fuel gauge and indicator lamps electronic components.
1. Introduction to car dashboards noun
car dashboard is a device that reflects the work status of each system of the vehicle. Usually by the speedometer, tachometer, oil pressure gauge, water temperature, fuel gauge and indicator lamps electronic components. Auto Meter is an important driver interfaces with the vehicle for information exchange. With the development of automotive electronics technology, information agencies and automobile driving conditions, parts of a significant increase in the driver while driving the vehicle, must be more and better informed about various vehicle and engine parameters are normal, in order to take timely measures to prevent accidents.
As electronic technology advances and new sensors and electronic display, emerging new components, automotive electronic instruments has been rapidly adopted. Currently used on automotive electronic instrument display devices are mainly the following: a light emitting diode, a vacuum screen display, a liquid crystal display.
2. Electronic instruments Category
In the first light emitting diode late 1960s used in digital watches, then gradually well known. Simple structure, small volume, long life, has been gradually replace incandescent bulbs used in the past the traditional instrument. But LED showing good results in darkening environmental conditions, and direct sunlight illegible. Applies only to a light emitting diode bar character information and graphic display. Vacuum Fluorescent Display encapsulated by a number of electrodes in a vacuum container composed of a glass, a high-speed flow of electrons collide with the fluorescent material to emit light.
Vacuum Fluorescent light-emitting diode display ratio has a wider color gamut, only considerably operating voltage, color display can be carried out, and easy connection and a control circuit for the display of various characters and images. It has high reliability, easy to read, there are many colors to choose from, but easy to shatter.
The liquid crystal display is a schematic oblique direction change in applied electric field on the liquid crystal molecular array. Tilt direction of the liquid crystal molecules is changed, so that its optical properties change. The liquid crystal display having a display area, display clear, low energy consumption, the display is not affected in the direct sunlight, the color filters can display different advantages. At present, the LCD is widely used.
