Double-screen-stacked combined colored total-liquid-crystal-display car instrument

Abstract

The invention discloses a double-screen-stacked combined colored total-liquid-crystal-display car instrument. The instrument comprises an instrument mask, a screen ring, a segment code screen, a colored liquid crystal screen, a light-guide mask, a PCB and a bottom shell. The double-screen-stacked combined colored total-liquid-crystal-display car instrument has the advantages that the instrument is stacked and assembled by the colored liquid crystal screen and the segment code screen, various indexes and functions of a car are displayed in a combined manner, the instrument is simple in structure, free of pointers and a transmission motor, safe and reliable in circuit and resistant to vibration, and 60% of manufacturing cost is saved as compared with a similar colored total-liquid-crystal-screen instrument; the circuit principle of the instrument is advanced, the instrument is provided with a main chip IC, a voltage-stabilizing chip WC, various protecting circuits, filter circuits and DC-DC conversion circuits, and the instrument is provided with a loudspeaker which can give out warning voices; the instrument is connected with a power supply in the car, sensor power supplies on various parts of the car, a switching switch and the circuit board can be connected through the instrument, and the switching switch can switch the display modes such as a traditional mode or a modern segment code display mode of the instrument.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile instrument with double-screen superposition and combined color full liquid crystal display. Background technique [0002] As a means of transportation, the development of automobiles has entered the fast lane, gradually moving toward high-end, energy-saving, low-carbon emissions, complete functions, and easy and convenient driving. Automobile instrumentation is particularly important. It is necessary to realize professional and comprehensive display of vehicle information as soon as possible. To achieve accurate display, clear display. At present, the instruments used in high-end cars have replaced the original instrument panel display by full LCD screen display, realizing comprehensive and clear display, but the production cost of full LCD screen instrument is high, which directly increases the production cost of the whole vehicle. Reduced the market comp...
