Detailed description of the invention
Fig. 1 is the LED flexible display screen schematic diagram that transparent membrane of the invention forms.
Fig. 2 is display screen structure schematic diagram of the present invention with driving.
In figure: 1, flexible transparent film (having etched conductive film circuit), 2, LED chip, 3, protective film, 4, flexible wire

Specific embodiment
The present invention is further described through with reference to the accompanying drawing.
A kind of production of the LED display of transparent membrane composition includes two steps:
Step 1 is the production of the LED flexible display screen of flexible and transparent, as shown in Figure 1, including one layer of flexible transparent film
1, one layer of conductive film circuit being plated on flexible transparent film 1 and several LED chips 2.LED chip 2 passes through ITO conductive electrode
Or electrically conductive ink is connected to plated film and has etched on the flexible transparent film 1 of conductive film circuit.Its specific implementation process are as follows:
Layer of conductive film such as ITO tin indium oxide conductive film is plated to the side of flexible transparent film 1, the thickness of conductive film is wanted
Much smaller than flexible transparent film 1 thickness (present invention by the thickness control of conductive film be lower than 1 thickness one of flexible transparent film
Below a order of magnitude), the amount of crimp of flexible transparent film 1 otherwise will be lost significantly, the method for then using laser ablation, benefit
The route for wanting arrangement is drawn with CAD processing software, it is flexible saturating to being plated to further according to point well laid line map is realized
The conductive film ITO conductive film on bright 1 surface of film carries out laser-induced thermal etching, thus by conducting wire required between 2 pin of LED chip
It etches and, during laser ablation, because the resistivity of conductive film wants high relative to copper, silver wire, to whole
For a circuit system, in order to make entire circuit, electric current is identical so that each 2 display brightness of LED chip is the same everywhere, away from
Conducting wire Ying Yuekuan that is remoter with a distance from 1 both sides of flexible transparent film, etching.Finally several LED chips 2 are led by ITO
Electrode or electrically conductive ink are connected on the flexible transparent film 1 for having etched conducting channel.Last bonding protective film 3 is to play
Protect insulating effect.
Step 2 is that the LED flexible display screen of transparent membrane composition is connected by flexible circuit board 4 with external drive, is driven
Display screen carries out the display of the information such as character image video, as shown in Fig. 2, including the LED that transparent membrane as shown in Figure 1 forms
Flexible display screen, several FPC (flexible circuit board 4) and several driving items 5.FPC (flexible circuit board 4) one end is connected and fixed
Designated position onto driving item 5, the other end then pass through the sticking conductive jelly of the tool such as polyvinyl butyral (PVB) with
Circuit on the LED display of flexible and transparent is connected.Its specific implementation process are as follows: will be such as Fig. 1 transparent membrane composition obtained
LED flexible display screen on the route of laser ablation have sticking jelly and FPC by polyvinyl butyral (PVB) etc.
Route in (flexible circuit board 4) is connected one by one.Because the resistivity of conductive film is bigger than copper, silver wire, to make every
Complete conducting wire (from the conducting wire of the LED chip 2 on the LED flexible display screen that driving item 5 is formed to transparent membrane) resistance everywhere
The identical resistance it is necessary to know conducting wire in FPC (flexible circuit board 4), to change transparent membrane by the method for laser ablation
The line width of the LED flexible display screen conducting channel of composition guarantees that impedance is consistent, to reach each 2 display brightness of LED chip
It is identical, due to using laser ablation so conducting wire can intersect realization multilayer.Then by FPC (flexible circuit board 4)
The other end be connected with driving item 5, it is each to drive item 5 that be cascaded, to drive more LED chips 2.
The present invention is not limited to the present embodiment, any equivalent concepts within the technical scope of the present disclosure or changes
Become, is classified as protection scope of the present invention.
