Abstract

The invention proposes a system and method for low-power consumption driving of a full-segment code meter indicator light, including a power module, a microcontroller, a segment-code LCD driver chip, and a segment-code LCD; the power module, the microcontroller, the segment-code The LCD screen driver chip is connected to the segment code LCD screen, and the microcontroller is connected to the segment code LCD screen driver chip; the microcontroller is used to control the segment code LCD screen driver chip, and the segment code LCD screen driver chip is used to drive the segment code LCD screen. The code break indicator on the screen, the power supply module, is used to supply power to each module; the present invention enables the instrument to wake up the system regularly under the condition of dormancy, operate the code break LCD IO port, and realize the transmission of the LCD indicator light.

Description

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