Abstract

The invention provides a low-power-consumption driving system and method for a full-segment-code instrument indicator lamp. The system comprises a power module, a microcontroller, a segment-code liquid crystal screen driving chip and a segment-code liquid crystal screen. The power supply module is connected with the microcontroller, the segment code liquid crystal screen driving chip and the segment code liquid crystal screen, and the microcontroller is connected with the segment code liquid crystal screen driving chip; the microcontroller is used for controlling the segment code liquid crystal screen driving chip, the segment code liquid crystal screen driving chip, the broken code indicating lamp used for driving the segment code liquid crystal screen, and the power supply module, and is used for supplying power to each module. According to the invention, under the condition that the instrument is dormant, the system can be awakened regularly, the broken code liquid crystal IO port is operated, and the liquid crystal indicator light is transmitted.

Description

technical field [0001] The invention relates to the field of low-power driving of indicator lights, in particular to a system and method for low-power driving of full-segment code instrument indicator lights. Background technique [0002] The segment code LCD screen has the advantages of low requirements on the main control chip, simple software, and low cost of controlling the LCD screen and the main control. The all-break code LCD screen requires that the chromaticity difference ΔE<2 for the integrated black effect of the instrument. The traditional design of the anti-theft indicator light needs to dig holes in the liquid crystal polarizer instead of making it on the liquid crystal, so it cannot meet the user's requirements for a one-piece black effect. If the anti-theft light is made on the LCD, it is necessary to light up the anti-theft light broken code LCD under the sleep condition of the instrument, and at the same time meet the requirement of low power consumptio...
