Abstract

The invention discloses a multi-state bright block belt instrument, and a scanning circuit digital LED screen intelligent component electric vehicle. The instrument comprises a central processing circuit, a communication and interface circuit, a power supply circuit, a display and a PCB. The display comprises an LED array, an LCD screen or a VFD screen, and is directly welded on the PCB. The central processing circuit comprises an LCD screen driving chip, a VFD screen driving chip, an LED driving chip or an mcu chip. The central processing circuit comprises an LED driving circuit which comprises an XY scanning circuit. The display content of the display is displayed in a bright block band mode, and the larger the value is, the larger the number of the bright blocks lighted by the bright blocks is. The bright block belt can be in a transverse line type, a vertical line type, an oblique line type, a curve type or a combined type. The bright block belt comprises an equal-width type or a gradually-wide type. The curve type comprises an upper bending type, a lower bending type, a left bending type, a right bending type or an inclined bending type. Each bright block can be square, round or polygonal. In addition, the display effect can be improved by combining the numerical codes of the beveled large-code-number gradually-widened-segment-code gradually-widened fonts.

Description

technical field [0001] In the field of electronic technology, specifically electric vehicle electrical appliances. Background technique [0002] For the convenience of describing the present invention, the following conventions are used: "Power" refers to the parameters related to the remaining energy of the battery, the most accurate is the number of ampere hours. Approximate battery voltage or its ratio; "Electric vehicle" refers to vehicles powered by batteries, including four-wheel electric vehicles, electric sightseeing vehicles, electric sweepers, electric forklifts, children's vehicles, electric bicycles, electric mopeds, electric motorcycles, and electric tricycles; "LED light" refers to LED light-emitting devices.
