Abstract
The invention relates to a one-eighth scanning LED display screen which is composed of a plurality of unit plates. Each unit plate comprises at least two scanning units and a row decoder, wherein the scanning units are respectively in communication with the row decoder. Each scanning unit comprises a driving chip and a plurality of LEDs, wherein the LEDs are respectively in communication with the driving chip. Compared with a one-fourth scanning LED display screen on the market at present, the one-eighth scanning LED display screen has the advantages that the required driving chips are greatly decreased, the cost is low, and the chip damaging probability is also reduced.
Description
Technical field
The present invention relates to open air, semi-outdoor monochromatic LED display screen field, relate in particular to a kind of eight/one scan LED display.
Background technology
Existing open air, semi-outdoor LED display are mostly the monochromatic LED display screen of P10 or P16 type.And outdoor, to LED, brightness has higher requirements semi-outdoor display screen, therefore adopts four/scan mode that sweeps.In conjunction with Fig. 4, each scan period was comprised of four phase non-overlapping copies T1, T2, T3, T4 time periods, in each open air, semi-outdoor P10 monochrome cells plate, within each time period, there are four row signals work simultaneously and corresponding four lines LED is lit, as T1 time period H1, H5, H9, the capable signal of H13 are worked and corresponding four lines LED is lit simultaneously.The drive IC of using as the monochromatic LED display screen of Fig. 3 tetra-/one scan needs 16, and each IC drives at least 4 LED lamps.Therefore the shortcoming of monochromatic LED display screen is: bad sheet probability is large, and the quantity of drive IC is more, and cost is also corresponding higher.
Summary of the invention
The object of the invention is to overcome the deficiency of above prior art, and a kind of eight/one scan LED display is provided, and specifically has following technical scheme to realize:
Described eight/one scan LED display, by some cell boards, formed, each cell board comprises at least two scanning elements and line decoder, described scanning element communicates to connect with line decoder respectively, each scanning element comprises driving chip and some LED, and described LED is connected with driving chip communication respectively.
The further design of described eight/one scan LED display is, described LED is monochromatic LED.
The further design of described eight/one scan LED display is, described monochromatic LED communicates to connect with line decoder respectively.
The further design of described eight/one scan LED display is, the monochromatic LED in described scanning element is eight.
The further design of described eight/one scan LED display is, described eight/one scan LED display comprises two scanning elements.
The further design of described eight/one scan LED display is, described driving chip Wei Ba road constant-voltage LED driving chip.
The further design of described eight/one scan LED display is, described display screen is P10 type.
Advantage of the present invention is as follows:
Eight/one scan LED display provided by the invention is than present four/one scan LED display on the market, and the driving chip needing greatly reduces, and cost is low, has also reduced bad sheet probability.
Accompanying drawing explanation
Fig. 1 is eight/one scan LED display circuit diagram provided by the invention.
Fig. 2 is the view of each LED in the engineering of LED display work shown in Fig. 1.
Four/one scan LED display the circuit diagram of Fig. 3 for providing in background technology.
Fig. 4 is the view of each LED in the engineering of LED display work shown in Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, the present invention program is elaborated.
As Fig. 1, eight/one scan LED display provided by the invention, is comprised of some cell boards, and each cell board comprises at least two scanning elements and line decoder, and scanning element communicates to connect with line decoder respectively.Each scanning element comprises driving chip and some LED.LED is connected with driving chip communication respectively.Wherein LED is monochromatic LED.Monochromatic LED communicates to connect with line decoder respectively.Drive chip Wei Ba road constant-voltage LED to drive chip.
Scanning element in the present embodiment in each cell board is two.Monochromatic LED in scanning element is eight.Selected driving chip model is 74HC595H, and display screen is P10 type.
In conjunction with Fig. 2, the open air of the present embodiment, semi-outdoor P10 monochromatic LED display screen be eight/sweep, each scan period was comprised of eight phase non-overlapping copies T1, T2, T3, T4, T5, T6, T7, T8 time periods.In each cell board, within each time period, there are two row signals to work simultaneously and two corresponding row LED are lit, as T1 time period H1, the capable signal of H9 are worked and two corresponding row LED are lit simultaneously.
Drive IC in existing open air, semi-outdoor monochromatic LED display screen unit panel needs 16, and drive IC in open air provided by the invention, semi-outdoor monochromatic LED display screen unit panel only needs 8 to be the former half, saved the bad sheet probability that cost also reduces LED drive IC.
As Fig. 2, Fig. 4, consider in the unit interval, eight/sweep time that every row LED is lit than four/to sweep the time that every row is lit short, and in the present embodiment, need the driving chip 74HC595H that provides, eight paths of LEDs can be driven simultaneously, the brightness that four/one scan display screen is identical can be reached.
