Abstract

The invention discloses an automobile instrument shell and a backlight module. The backlight module comprises an anti-surge circuit, a buzzer drive circuit, a comprehensive data display circuit, a backlight adjustable circuit, an expansion indication lamp drive circuit, an anti-static device and a CPU. The output end of the anti-surge circuit is connected with the power input end of the CPU, the power input end of the buzzer drive circuit, the power input end of the comprehensive data display circuit, the power input end of the backlight adjustable circuit and the power input end of the expansion indication lamp drive circuit. The signal output end of the comprehensive data display circuit is connected with the signal input end of the backlight adjustable circuit, the buzzer signal output end of the comprehensive data display circuit is connected with the signal input end of the buzzer drive circuit, the indication lamp signal output end of the comprehensive data display circuit is connected with the signal input end of the expansion indication lamp drive circuit, and the signal output end of the expansion indication lamp drive circuit is connected with the signal input end of the backlight adjustable circuit.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to an automobile instrument casing and a backlight assembly. Background technique [0002] In the prior art, there is no structure for directly installing the backlight assembly on the automobile instrument casing, and the backlight assembly is directly installed on the PCB assembly, while the PCB assembly is installed in the casing, and the casing is opened at the position facing the backlight assembly. To make way for the gap, a screen panel is also installed on the casing, and an LCD window is opened on the screen panel, and the LCD window is facing the LCD display area of ​​the backlight assembly. In this way, the backlight assembly is positioned through the PCB assembly, while the screen panel is positioned through the housing. Due to inconsistent positioning references, it is very easy to cause the LCD display area on the backlight assembly and the LCD window on the screen p...
