Abstract

The invention belongs to the technical field of LED (Light Emitting Diode) Nixie tube display driving, and provides a dish washing machine and an LED Nixie tube display driving circuit and method thereof. The LED Nixie tube display driving circuit which comprises a main control processor and a display driving module is adopted; display data stored in a storage space of the display driving module is zeroed after the main control processor is electrified; data to be displayed is subjected to segment bit data conversion processing to obtain Nixie tube display data; the Nixie tube display data is stored into the storage space of the display driving module; finally, a common anode LED Nixie tube is displayed by the display driving module according to the Nixie tube display data; the whole LED Nixie tube display driving circuit is low in cost, and the display driving of the common anode LED Nixie tube can be stably and reliably realized.

Description

technical field [0001] The invention belongs to the technical field of LED digital tube display driving, and in particular relates to a dishwasher and its LED digital tube display driving circuit and method. Background technique [0002] At present, in household appliances, in order to display various prompt information, LED digital tubes are used as the display medium. For the driving methods of LED digital tubes, the following three types are usually used: [0003] 1. By adopting three-stage tube drive and coordinating with the control software to use dynamic scanning mode for data control so that the LED digital tube can realize the display function, the connection and wiring of the circuit used in this driving mode are too complicated and occupy the input and output ports of the single-chip microcomputer There are many resources, and there are too many connecting lines between the main control board and the display board, which will increase the cost virtually and direct...
