Abstract
The utility model relates to a chest card capable of displaying by a light-emitting diode (LED) display screen; the chest card consists of a lithium battery, a battery charge-discharge circuit, a universal serial bus (USB) interface, a key switch, a singlechip microcomputer circuit, a flash memory chip, an LED driving circuit and the LED display screen, wherein the battery charge-discharge circuit is respectively connected with the lithium battery and the USB interface; the singlechip microcomputer is respectively connected with the battery charge-discharge circuit, the USB interface, the key switch, the flash memory chip, the LED driving circuit and the LED display screen; and the LED driving circuit is connected with the LED display screen. The LED display chest card can be supplied with power by the lithium battery and the USB interface; the content to be displayed is written into the flash memory chip by the singlechip microcomputer after the USB interface is communicated with a computer; and the changeable content can be displayed on the LED display chest card after the key switch is turned on.
Description
Technical field
The utility model relates to a kind of LED and shows chest card, specifically, relates to a kind of LED that can change displaying contents and shows chest card.
Background technology
At present, conventional chest card is all papery, paper is easy to bad, and attractive in appearance not, plastic casing that also needs hard etc. is protected and is beautified, and the content above this traditional chest card can not be changed, as changing content, need to again make card, waste paper, printing ink, human and material resources, and also change procedure is veryer long.
The utility model content
Can not change in order to solve papery chest card content, the use limitation of the short grade of visual range, the utility model provides a kind of LED to show chest card, and this LED shows that the content that chest card can will show chest card fast changes, and energy-conserving and environment-protective, brightness is high, decipherment distance is far away.
The technical scheme that the utility model is taked is: show on chest card at LED, lithium battery, battery charging and discharging circuit, USB interface, keyswitch, single chip circuit, FLASH storage chip, LED drive circuit, LED display are arranged, lithium battery and USB interface are connected to the battery charging and discharging circuit, single chip circuit connects battery charging and discharging circuit, USB interface, keyswitch, FLASH storage chip, LED drive circuit, LED display, and LED drive circuit is connected with LED display.Utilize lithium battery and USB interface to show the chest card power supply to LED, use USB interface with computer communication, the content that will show to be write the FLASH storage chip by single chip circuit, open keyswitch, just can show the content that on chest card, demonstration can change at LED.
The beneficial effects of the utility model are, the Modify rapidly content that will show on request, and displaying contents is eye-catching, and decipherment distance is far away, and can reuse.
