Abstract
The utility model discloses an LED display screen, comprising a plurality of LED pixel die set, wherein the LED pixel die set has a circuit board and a plurality of LED unit welded on the circuit board, the LED unit comprises red-green LED unit and the red-blue LED unit, the red-blue LED unit is an LED unit packaged with red and blue luminous chips, the alternating colors has colorful effect when displaying flowing characters and simple logo, suitable for small sized led display screen. Compared with the 3528 RGB LED, the display screen uses red-green LED unit and red-blue LED unit, many luminous chips are saved, thereby saving constant current drive IC for controlling the luminous chips, and the qualification rate can be raised in the manufacturing process when fewer chips are used, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of LED display, specifically relates to a kind of compact LED display screen that shows flowing water literal and simple logo that is mainly used in.
Background technology
LED---Light Emitting Diode, being light emitting diode, is a kind of semiconductor solid luminescence device, and it is to utilize the solid semiconductor chip as luminescent material, when two ends add forward voltage, the charge carrier in the semiconductor takes place compoundly to cause photo emissions and produce light.LED can directly send red, yellow, blue, green, blue or green, orange, purple, white light.
Printed circuit board (PCB)---PCB (Printed Circuie Board) normally on the insulation material, by predetermined design, makes printed wiring, prints assembly or printed circuit that both combine.
Constant-current driving IC---Constant Current IC is meant that in the working environment that drive IC allows, the predetermined electric current value was characterized in that the variation of external impedance is minimum to the influence of its output current when constant output designed.
LED display---LED Panel, it is a kind of display mode by control LED, leans on the light on and off of LED to come the display screen of various information such as display text, figure, image, animation, market, video, video signal.
Existing its structure of LED full color display and principle are as follows: according to the branch requirement of the dot spacing of LED display, 3528 RGB LED 1 (package dimension be 35 * 28, include the surface attaching type light emitting diode of three kinds of luminescence chips of red, green, blue 11,12,13) evenly are welded on the PCB 2, and use constant-current driving IC to control the electric current of three kinds of colour light emitting chips, size according to the different electric currents of shades of colour luminescence chip, mix out multiple color, make it reach full-color effect and come work.The LED pixel module of this LED full color display as shown in Figure 2.This LED full color display exists among following defective: A, the 3528 RGB LED luminescence chip color more, occurs bad in processing procedure easily; B, since luminescence chip constant-current driving IC more, that be used to control luminescence chip is also more, processing charges is high and the cost of control aspect endways also than higher, thereby cause whole cost than higher; C, particularly at the client who uses small-sized screen display screen, on cost, do not have advantage, general compact LED display screen is mainly used in display text and simple logo.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of LED display, and this LED display can reach the effect of display color flowing water literal and simple logo, and cost is low, simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of LED display, have some LED pixel modules, described LED pixel module has wiring board and is welded in some LED monomers of wiring board, described LED monomer is divided into two kinds of red green LED monomer and red and blue LED monomers, described red green LED monomer is the inner LED monomer that is packaged with emitting red light chip and green emitting chip, and described red and blue LED monomer is the inner LED monomer that is packaged with emitting red light chip and blue-light-emitting chip.
Further technical scheme of the present utility model is:
Described LED pixel module has at least one group and is the set that rectangular LED monomer of arranging is formed by 16 * 16, has 16 * 8 in the described set and is rectangular red green LED monomer of arranging and 16 * 8 and is rectangular red and blue LED monomer of arranging.
The beneficial effects of the utility model are: each LED pixel module of the utility model LED display has at least one group and is the set that rectangular LED monomer of arranging is formed by 16 * 16, having 16 * 8 in the described set is rectangular red green LED monomer of arranging and 16 * 8 and is rectangular red and blue LED monomer of arranging, described red green LED monomer is the inner LED monomer that is packaged with emitting red light chip and green emitting chip, described red and blue LED monomer is the inner LED monomer that is packaged with emitting red light chip and blue-light-emitting chip, when showing flowing water literal and simple logo, color alternately can coloured effect, relatively be applicable to the compact LED display screen, owing to adopted red green LED monomer and red and blue LED monomer all to adopt 3528 RGB LED will save a lot of luminescence chips than tradition, and then also saved the constant-current driving IC that is used to control luminescence chip, and luminescence chip has lacked the yield that can improve in processing procedure, make cost be minimized, save cost about 20%, for the compact LED display screen client who only needs to show flowing water literal and simple emblem, the utility model has more competitive edge.

Embodiment
Embodiment: a kind of LED display, have some LED pixel modules, described LED pixel module has wiring board 2 and is welded in some LED monomers of wiring board, described LED monomer is divided into 4 two kinds of red green LED monomer 3 and red and blue LED monomers, described red green LED monomer 3 is the inner LED monomer that is packaged with emitting red light chip 11 and green emitting chip 12, and described red and blue LED monomer 4 is the inner LED monomer that is packaged with emitting red light chip 11 and blue-light-emitting chip 13.
Described LED pixel module has two groups and is the set that rectangular LED monomer of arranging is formed by 16 * 16, has 16 * 8 in every group of described set and is rectangular red green LED monomer of arranging and 16 * 8 and is rectangular red and blue LED monomer of arranging.Should be rectangular red green LED monomer of arranging and 16 * 8 by 16 * 8 is 16 * 16 that rectangular red and blue LED monomer of arranging forms and is the minimum display unit that rectangular set of arranging is Chinese character or Japanese, when showing flowing water literal and simple logo, color alternately can coloured effect, relatively is applicable to the compact LED display screen.Owing to adopted red green LED monomer and red and blue LED monomer all to adopt 3528 RGB LED will save a lot of luminescence chips than tradition, and then also saved the constant-current driving IC that is used to control luminescence chip, and luminescence chip has lacked the yield that can improve in processing procedure, make cost be minimized, save cost about 20%.For the compact LED display screen client who only needs to show flowing water literal and simple emblem, this example has more competitive edge.
