The invention discloses an electric control board LED lamp state display method and an electric control board LED lamp state display device. An electric control board is provided with at least one LED lamp. The method comprises the following steps: judging whether the at least one LED lamp meets preset display conditions; acquiring to-be-displayed state information of the at least one LED lamp according to the preset display conditions if the at least one LED lamp meets the preset display conditions; determining the number of flickering times of the at least one LED lamp according to a first preset encoding rule and the to-be-displayed state information of the at least one LED lamp; and controlling the flickering of the at least one LED lamp at a preset frequency according to the number of flickering times of the at least one LED lamp so as to enable a user to calculate the number of flickering times of the at least one LED lamp and obtain displayed state information of the at least one LED lamp according to the first preset encoding rule and the number of flickering times of the at least one LED lamp at the end of flickering of the at least one LED lamp. By adopting the method, an LED lamp can indicate more states, and more information can be expressed.
Description
technical field [0001] The present invention relates to the technical field of LED (Light Emitting Diode, light-emitting diode), in particular to a method, a device and an electric control board for displaying states of an LED light on an electric control board. Background technique [0002] At present, there are often some information in the electronic control panel of home appliances that need to be indicated by digital tubes or LED lights. For example, when using 8-segment digital tubes for signal indication, the digital combination of 8-segment digital tubes can be used to display a lot of information. However, in order to save costs, LED lights are often used for some signal indications. [0003] At present, LED lights are used to indicate information, and generally have the following two types: 1) A state is indicated by a long light (such as a normal state), a state is always off (such as a shutdown state), and a state is blinked (such as a fault) ; 2) Different fau...
