Abstract
The invention discloses an LED display device with a ground color. The LED display device comprises a signal generator, a control card and an LED display screen module, wherein the signal generator is connected with the control card through signals; the control card is connected with the LED display screen module through signals; the LED display screen module consists of a PCB board, main lighting LED lamp beads and ground color LED lighting lamp beads; the main lighting LED lamp beads and the ground color LED lighting lamp beads are arranged on the PCB board; the ground color LED lighting lamp beads are uniformly inserted among the main lighting LED lamp beads; and the signal generator can simultaneously generate two groups of independent control signals which control the main lighting LED lamp beads and the ground color LED lighting lamp beads respectively through the control card. The LED display device with the ground color can ensure that an LED display screen realizes display with the ground color, and has the characteristics of simple structure and low price.
Description
[technical field]
The present invention relates to the led lighting technical field, relate in particular to and use the display device that LED carries out literal, graphic presentation.
[background technology]
LED display has monochrome, dual base color and three primary colours (full-color) from constituting the classification of luminous point color; Monochromatic only a kind of color of each luminous point (based on redness) can't have been accomplished background color; Each luminous point of dual base color has red pipe and green pipe, and each luminous point has one red one green (as P10 module) and two red one green (as P12, P14, P16, P20) on physical distribution, and the ratio that is to say red pipe and green pipe is 1: 1 and 2: 1; If accomplish to be with background color to show, must accomplish red, green dichromatism fluorescent tube is separately controlled and made the mutual Compositing Change glow color of dichromatism light, cost is very high like this; And three primary colours (full-color) ratio red, green, blue luminous point is 1: 1: 1 or 2: 1: 1, and these distributed architectures are made background color and will be caused the cost can be higher.
[summary of the invention]
The present invention is directed to the above-mentioned defective of prior art, a kind of LED display device of simple in structure, cheap band background color is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of LED display device with background color, comprise signal generator, control card, the LED display module, signal generator is connected with the control card signal, control card is connected with LED display module signal, described LED display module is by pcb board, main light emission LED lamp pearl, background color LED electroluminescent lamp pearl constitutes, main light emission LED lamp pearl and background color LED electroluminescent lamp pearl all are installed on the pcb board, described background color LED electroluminescent lamp pearl is evenly mixed and is inserted in the middle of the main light emission LED lamp pearl, described signal generator can produce two groups of independently control signals simultaneously, these two groups independently control signal control main light emission LED lamp pearl and background color LED electroluminescent lamp pearl respectively by control card.
Wherein, the ratio of main light emission LED lamp pearl, background color LED electroluminescent lamp pearl is 4: 1～16: 1.
As can be seen from the above technical solutions, the present invention sets up one group of background color LED electroluminescent lamp pearl on the basis of original main light emission LED lamp pearl, increases the control signal of a background color LED electroluminescent lamp pearl again, promptly realizes the demonstration of band background color.In fact only increase by one group of background color LED electroluminescent lamp pearl from hardware, the cost increase seldom, cost is very low.But, band background color LED display of the present invention not only can the display text content, also can demonstrate another color on the surface of word content, and color also can pre-set the program transformation display mode by signal generator, background color can be white, purple, blueness, green etc., display mode can be bright entirely, chase, fan out, rhombus expansion, music fountain etc. (similar neon bulb), reach and do things creatively, more attracting effect.
[description of drawings]
Fig. 1 is an one-piece construction synoptic diagram of the present invention.
Fig. 2 is LED display mode configuration figure of the present invention.
[embodiment]
The present invention is further detailed explanation below in conjunction with embodiment.
Extremely shown in Figure 2 referring to Fig. 1, the LED display device of band background color of the present invention, comprise signal generator 1, control card 2, LED display module 3, signal generator 1 is connected with control card 2 signals, control card 2 is connected with LED display module 3 signals, described LED display module is by pcb board, main light emission LED lamp pearl, background color LED electroluminescent lamp pearl constitutes, main light emission LED lamp pearl and background color LED electroluminescent lamp pearl all are installed on the pcb board, described background color LED electroluminescent lamp pearl is evenly mixed and is inserted in the middle of the main light emission LED lamp pearl, described signal generator can produce two groups of independently control signals simultaneously, these two groups independently control signal control the bright of main light emission LED lamp pearl and background color LED electroluminescent lamp pearl respectively by control card, state goes out.Wherein, the ratio of main light emission LED lamp pearl, background color LED electroluminescent lamp pearl is 4: 1～16: 1.
Referring to shown in Figure 2, LED display module 3 is made of pcb board 31, main light emission LED lamp pearl 32, background color LED electroluminescent lamp pearl 33.Module is a function element of assigning another kind of glow color in existing monochromatic module with 4: 1 ratios, with outdoor P12.5 modules are example, module at a block length 40 * 20CM, it is long 32 points that luminous point is arranged, high 16 degree are used for the display text content, assign 16 points on the length, assign 8 points to be used to show background color on the height, then the distance between every bit is exactly 25CM, these 128 points are controlled with four 74HC595, and control card is the function element that is made of single-chip microcomputer.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
