Abstract

The utility model provides a P16 outdoor full-color LED unit board module. The technical scheme of the module includes that the module comprises a plurality of pixel points consisting of red LEDs, green LEDs and blue LEDs, the red LEDs are connected with pins of a first driving chip in a one-to-one corresponding manner, the green LEDs are connected with pins of a second driving chip in a one-to-one corresponding manner, the blue LEDs are connected with pins of a third driving chip in a one-to-one corresponding manner, and additionally, a current control module is further connected with the first driving chip, the second driving chip and the third driving chip. The unit board module adopting the scheme has the advantages of simple circuit, easiness of maintenance, reduction of cost and improved production efficiency.

Description

The outdoor all-colour LED cell board of a kind of P16 module
The utility model relates to a kind of LED cell board, the outdoor all-colour LED cell board of especially a kind of P16 module.。
Background technology
In the prior art, technique known is that existing LED cell board is that LED core is integrated into lattice module or pixel cell, be welded in then on the PCB, combine with driving circuit, line control circuit, adjustable resistor and form, the drive IC output pin is to the control of carrying out " point is to row " between the pixel, display effect is bad, poor stability, and the luminance loss is big; And existing LED cell board generally adds 3 adjustable resistors, is used for regulating the brightness of the LED light emitting diode of three kinds of colors forming pixel respectively.Owing to be difficult for regulating, consume man-hour, greatly reduce production efficiency.This is the existing in prior technology weak point.
Summary of the invention
The purpose of this utility model is exactly at the existing in prior technology deficiency, and the technical scheme of the outdoor all-colour LED cell board of a kind of P16 module is provided, and the cell board module circuit of this scheme is simple, be easy to safeguard, and has reduced cost, has improved production efficiency.
This programme is realized by following technical measures: the outdoor all-colour LED cell board of a kind of P16 module, include several by red LED, green LED, the pixel that blue led is formed, the characteristics of this programme are: the pin of the described red LED and first chip for driving connects one to one, the pin of the described green LED and second chip for driving connects one to one, the pin of described blue led and the 3rd chip for driving connects one to one, in addition, also have a current control module and described first chip for driving, second chip for driving is connected with the 3rd chip for driving.
Described current control module comprises first adjustable resistance, second adjustable resistance and the 3rd adjustable resistance, described first adjustable resistance is connected with described first chip for driving, described second adjustable resistance is connected with described second chip for driving, and described the 3rd adjustable resistance is connected with described the 3rd chip for driving.
The beneficial effect of this programme can learn according to the narration to such scheme, because LED of all kinds connects one to one with the corresponding driving pin of chip respectively in this scheme, and promptly point-to-point control, display effect is good, good stability, luminance loss are also less; Described three chip for driving are external three adjustable resistances respectively, by regulating the output current that resistance comes the controlling and driving chip, the electric current of chip for driving directly influences the brightness of LED light emitting diode, like this by setting the resistance of chip for driving outer meeting resistance, the brightness ratio that has realized pixel cell RGB is the purpose of 3:6:1, even cell board has reached the white balance effect.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
