Description
Technical field
The present invention relates to field of display technology, more particularly to a kind of OLED display panel and production method.
Background technique
The type of display technology is more, including liquid crystal display (Liquid Crystal Display, LCD) and organic light emission
Diode shows (organic light-emitting diode, OLED) etc..What is wherein had a great attraction is that OLED is shown,
It has many advantages, such as self-luminous show, frivolous power saving, can also based on flexible material and flexible display be made, can be curled,
Fold or as wearable device a part.The principle of luminosity of OLED be deposit between two electrodes it is very thin organic
Luminescent material passes to electric current to luminous organic material, causes to shine with compound by carrier injection.
Graphene is the nano material that known world is most thin, most hard, it is almost fully transparent, only absorption
2.3% light, and the resistivity of graphene is extremely low, only 10-8Ω m is a kind of transparent conductor with fabulous prospect, is suitble to
For making transparent touch screen, tabula rasa, even solar battery.In addition, correlative study shows the laminar nano of graphene
Structure has the characteristic for absorbing electromagnetism, is a kind of novel absorbing material.
Nano-silver thread (silvernanowire) technology is that nano-silver thread ink material is applied to plastic cement or glass base
On plate, radium-shine photoetching technique is then utilized, portrays and the transparent conductive thin with Nano grade silver wire conductive network pattern is made
Film.Nano-silver thread is in addition to the electric conductivity for having silver excellent, due to the dimensional effect of Nano grade, also has excellent light transmission
Property, flexible resistance, be accordingly regarded as being the most possible material for substituting traditional ito transparent electrode.Again, nano-silver thread film has
There is lesser bending radius, and resistance change rate is smaller in bending, applies in the equipment with curved-surface display, such as intelligent hand
It is more advantageous when table, bracelet etc. are upper.
NFC (Near Field Communication) i.e. near field communication (NFC), the technology allow electronic equipment
Between carry out contactless Point-to-Point Data Transmission (in ten centimetres).This technology is drilled by contact-free formula RF identification (RFID)
Become, and backward compatible RFID, is mainly used for providing the logical of M2M (Machine to Machine) in the handheld devices such as mobile phone
Letter.Since near-field communication has natural safety, NFC technique is considered having in fields such as mobile-phone payments very big
Application prospect.
Currently, more and more electronic equipments especially dress class product and all start subsidiary NFC function in addition to common mobile phone
Energy.But due to the limitation of the shape of wearing class product and other small-size electronic equipments, size to electronic device and integrated
It is required that relatively high.Currently, the mode that generallys use of the NFC antenna for being integrated into interiors of products be on pcb board or FPC soft board, with
Metal routing is made into coil, and the pcb board or FPC soft board that this is then contained coil are attached on battery or shell.The disadvantage is that:
(1) NFC antenna occupies great space inside equipment, can not adapt to the design requirement of miniaturized electronics.
(2) conventional NFC antenna is to be made into loop construction by metal lead wire on pcb board or FPC soft board, then contains this
The pcb board or FPC soft board for having coil are attached on battery or shell.The repeated disassembled and assembled of battery, shell will lead to NFC antenna abrasion
Or contraposition is inaccurate, and then influences the transmission of NFC signal.
(3) since NFC communication is closer, in order to guarantee the intensity and stability of NFC signal, some electronic equipments are such as
Watch etc. proposes the demand that NFC antenna is put into display surface.
Existing that NFC antenna is integrated into the positive scheme of display screen, NFC antenna cabling uses the conductors such as silver, copper, and NFC days
The coil of line is put into outside viewing area and intermediate region hollow out, and NFC antenna cabling is avoided to block viewing area.But such side
In order to guarantee NFC antenna cabling space, NFC wire frame will be done very big case, so increase entire mould group viewing area with
Outer frame size.The program solves the problems, such as that conventional NFC antenna cabling is easy to wear, easy dislocation to a certain extent, but mistake
Big mould group frame size is equally unfavorable for the design of miniaturized electronics.
