The development in market.
By taking flexible LED display screen as an example, although some new technologies such as OLED (Organic in analogous technical fields
Light-Emitting Diode) etc. realize screen part can flexibility and can variability the characteristics of, but and fexible film
The technical issues of LED display is compared, and technical solution is different, and can not solve enlargement and the long-life of display screen.
In LED display field, it is desirable that LED display wants convenient transportation, screen body frivolous, convenient for disassembly and assembly and changeable can make
Type generallys use reduction unit box sizes in the prior art in order to reach this purpose to realize, but since LED is shown
Shield the limitation of the structure sizes such as the outer framework integrated, power-supply system, control system, encapsulation LED die, encapsulation driving chip,
Technical effect is not obvious, and also resulting in display screen has granular sensation, influences display effect.
Summary of the invention
In order to solve the deficiency of above-mentioned prior art, frivolous, dismounting transporter that the object of the present invention is to provide a kind of screen bodies
Just, moulding is changeable, while saving material, reduces production cost, and the ultra-thin all-colour LED film for improving the Pasting of production efficiency is aobvious
Display screen.
Invention thought of the invention: normal to replace using ITO or copper foil as conducting medium using transparent membrane as substrate
Advise printed circuit board;Replace the LED and driving chip routinely encapsulated with without encapsulation namely bare die LED and driving chip;
Give up outer framework, DC power supply and control system is plug-in, and using FPC as interface circuit, there is rubberizing at the mould group back side, can be directly
It pastes installation and forms display screen, since thin film shape changeable can be bent, or even fold, it is possible to it is aobvious to risk existing LED
The shape that display screen cannot achieve；Again since film itself is very frivolous, so ultra-thin and ultra-light may be implemented in display screen unit mould group,
Under traffic condition identical with current LED display, greater area of LED display screen can be transported, reduces dismounting transport

The bare die driving IC working principle of the ultra-thin all-colour LED film display screen of Pasting is as follows:
After chip electrification reset, IC11(Din1 is defaulted for the first time) data are received, chip detects that there is signal input in the port
It is then always maintained at port reception, if it exceeds 60ms does not receive data, is then switched to IC12(Din2) receive data, core
Piece detects that the port has signal input to be then always maintained at the port IC12(Din2) it receives, if it exceeds 60ms does not receive number
According to then again switching to IC11(Din1) receive data.IC11(Din1) and IC12(Din2) cyclic switching according to this, receives number
According to.
Chip electrification reset and after receiving constant current value setting command, starts to receive PWM setting command, after having received 24bit,
IC16(Dout1) and IC15(Dout2) port starts to forward IC11(Din1) or IC12(Din2) data sent are continued at end, are
Lower cascade chip provides PWM setting command.Before forwarding data, IC16(Dout1) and IC15(Dout2) port is always
Low level;If IC11(Din1) or IC12(Din2) end input Reset reset signal, chip IC 19(R), IC18(G), IC17
(B) port will make corresponding LED(001,002,003 according to the 24bit data output received) according to the PWM of corresponding duty ratio
Waveform issues the light of different colours, and chip resumes waiting for receiving new data, in the 24bit data for having received last batch
Afterwards, pass through IC16(Dout1) and IC15(Dout2) port forwarding data, chip is before being not received by Reset signal, IC19
(R), IC18(G), IC17(B) former output remains unchanged.
Chip uses automatic shaping retransmission technique, and signal will not distortion attenuation；For all chips being concatenated together, number
It is consistent according to the period of transmission.
