Description

LED allotypic marker display screen

Technical field

The utility model belongs to LED display device field, especially a kind of LED allotypic marker display screen.

Background technology

LED display commonly used at present is square or rectangle, can realize the Presentation Function of image.The problem that exists is the specific demand for the user, if occasion still adopts traditional square or rectangle LED display as market sign, advertising, shop be chain etc., will there be the big problem of investment, and square or rectangle LED display need be utilized computer control, can not off-line display, so use cost is also very high.

The utility model content

The purpose of this utility model provides a kind ofly can save investment, reduce use cost, satisfies a kind of LED allotypic marker display screen of user's specific demand.

The technical solution of the utility model is: LED allotypic marker display screen, comprise system control card and display screen body, what it is characterized in that described display screen body is shaped as crux or circle or triangle or trapezoidal, system control card is by control clamp single-chip microcomputer, on-chip memory, chip external memory and data scanning circuit are formed, on-chip memory, chip external memory links to each other with control clamp single-chip microcomputer respectively with the data scanning circuit, in on-chip memory or chip external memory, control clamp Single-chip Controlling sweep circuit sends to the display screen body with canned data and shows control clamp single-chip microcomputer with the information stores that receives.

Described on-chip memory and chip external memory are Flash type storer.

Described sweep circuit is the CPLD integrated circuit.

Effect of the present utility model is: display screen is designed to various moulding, and as the circle screen, crux screen and triangle screen etc. promptly satisfy user's particular demands, and can save investment.System control card is made up of control clamp single-chip microcomputer, on-chip memory, chip external memory and data scanning circuit, it mainly is the control integrated circuit board of a special use that systems control division divides, control integrated circuit board and mainly finish functions such as the scanning demonstration of system, graphics memory, temperature demonstration, clock demonstration, also remain with the PORT COM with computing machine simultaneously, can realize and functions such as the communication download of computing machine and clock adjustment.Chip microcontroller control computing is arranged on the control integrated circuit board, and the CPLD integrated chip is realized scan function.Control clamp single-chip microcomputer with the information stores that receives in on-chip memory or chip external memory, control clamp Single-chip Controlling sweep circuit sends to the display screen body with canned data and shows, like this can be under the few situation of cost investment, content such as display screen can display pattern, time, temperature, humidity, distinctive mark.On-chip memory and chip external memory are Flash type storer, situation video data in power down can not lost, therefore can realize off-line display, need not to adopt peripheral unit control such as computing machine, can be widely used in occasions such as market sign, advertising, shop be chain.

Below in conjunction with drawings and Examples the utility model is described further.
