Fig. 3 shows a kind of flattened structure schematic diagram of substrate, and Fig. 4 shows the section knot of I-I along the substrate shown in Fig. 3
Structure schematic diagram.In conjunction with shown in Fig. 3 and Fig. 4, substrate 11 includes flexible substrates 111 and transmission element 112.
Flexible substrates 111 and transmission element 112 in the form of sheets, and are linked together, to utilize flexible substrates 111 and transmission element
112 substrates 11 constituted are used as carrier, the structure sheafs such as setting machine LED layers, thin-film encapsulation layer.
It is important to note that substrate 11 is opposite with the folded portion of Folding screen when substrate 11 is installed on Folding screen
Bending region 11a is defined in the position answered, and non-bending region is defined in the position corresponding with the non-collapsible part of Folding screen of substrate 11
11b, it is believed that in addition to bending region 11a, rest part is non-bending region in region corresponding to substrate 11.Due to base
Plate 11 has bending region 11a corresponding with the folded portion of Folding screen, so that substrate 11 is after being set to Folding screen, it can
The folding for adapting to Folding screen needs.
In the embodiment, the light transmittance of transmission element 112 is greater than or equal to 90%, thus position corresponding to transmission element 112
With preferable light transmission.Transmission element 112 is located at non-bending region 11b, to provide good light permeability using transmission element 112
While energy, the bending performance in the region in addition to transmission element 112 of substrate 11 is not interfered with.By this structure setting,
While substrate 11 is able to maintain that preferable folding property, using transmission element 112 substrate 11 local location performance light transmittance compared with
High transmission region, to shield lower camera using transmission region setting or to shield the photosensitive elements such as lower fingerprint, and then Folding screen
It only needs to carry out aperture or light transmission processing in the position of corresponding photosensitive element, to maintain higher screen accounting.Due to transmission element
112 light transmittance is greater than or equal to 90%, so as to maintain the preferable using effect of photosensitive element.For example, utilizing folding
When lower camera is shielded in screen setting, camera and transmission element 112 are opposite, and ambient is corresponding to the transmission element 112 of Folding screen
Position is penetrated to camera, since transmission element 112 has preferable light transmission, so that the ambient light that camera receives
Line mass is truer, that is, is disturbed shooting effect that is less, and then can having obtained.
The material of flexible substrates 111 is with flexible or flexible one or more of polymer materials.Wherein, it polymerize
Object material can be acrylate, methacrylate resin, polyisoprene, vinylite, polyurethane resin, fibre
Tie up plain resin or resin.

(PPS), polyallyl ester (Polyallylate), polyimides (Polyimide, PI), polycarbonate (PC) or acetate propionate
Fluoropolymer resin for cellulose (CAP).
For using the material of substrate 11 as polyimides (Polyimide, PI), flexible substrates 111 can use PI liquid
The PI film being formed by curing.The light transmittance of PI film is less than or equal to 60%.PI film is able to maintain that certain light transmission under the light transmittance
Effect, and light pass through the PI film when, have part that can be absorbed by PI film, so that the glass transition temperature (Tg) of PI film can
Reach 450 DEG C or more, and then meets substrate 11 and made at low temperature polycrystalline silicon (LTPS, Low Temperature Poly-silicon)
Make the heatproof needs in technique.
Specifically, using low temperature polycrystalline silicon (LTPS, Low Temperature Poly-silicon) technique in substrate 11
When the organic diode layer of upper formation, in order to activate the impurity of organic diode layer effectively quickly, inside furnace environment temperature
Using 450 DEG C, and under the conditions of this temperature, heat treatment temperature is controlled at 450 DEG C.By in this present embodiment, due to the light transmission of PI film
Rate is less than or equal to 60%, and the glass transition temperature (Tg) of PI film is controlled at 450 DEG C or more, to avoid PI film subsequent
It is modified in low temperature polycrystalline silicon (LTPS, Low Temperature Poly-silicon) technique and leads to 11 structural damage of substrate.
PI film can be yellow PI film, although transmissivity only 60%, the glass transition temperature of yellow PI film
(Tg) 450 DEG C or more can be reached.
Flexible substrates 111 cover Folding screen folded portion and non-collapsible part, cut it is true say, flexible substrates 111 are not only
The bending region 11a of substrate 11 is formed, meanwhile, flexible substrates 111 also form the un-flexed region of substrate 11, not set in substrate
When transmission element 112, any position for the substrate 11 that flexible substrates 111 are constituted can realize bending, non-due to Folding screen
Folded portion itself is not foldable, thus when the installation of substrate 11 to Folding screen, the non-collapsible part of the corresponding Folding screen of substrate 11
Non- bending region 11b is not for the purpose of realizing bending, and the supporting element for being folded screen is fixed.It is this to utilize flexible substrates 111
The structure setting for covering entire substrate 11, so that in process, it is only necessary to consider the overall dimensions of Folding screen, time processing
Cheng Yuqi adaptable flexible substrates 111, and structural member of the transmission element 112 as the local transparent performance of enhancing substrate 11, it is full
The light of sufficient photosensitive element needs, therefore, 112 body of transmission element corresponding with the photosensitive elements such as camera or the lower fingerprint of screen
Product will not be very big, flexibly is located in flexible substrates 111 so as to compare, as long as including the Folding screen use of the substrate 11
When mobile terminal, the lower fingerprint of camera or screen and transmission element 112 being arranged in mobile terminal are opposite, to realize corresponding function
?.
Transmission element 112 is rounded or rectangular, and transmission element 112 is embedded at flexible substrates 111.
In some embodiments, transmission element 112 includes glass, so that preferable translucent effect be presented using glass.And glass
Glass is easier manufacture and obtains.
In conjunction with shown in Fig. 5 and Fig. 6, in some embodiments, the entire infrastructure or part-structure of flexible substrates 111 are configured to
Region 11a is bent, transmission element 112 includes two, and two transmission elements 112 are linked together bently by flexible substrates 111.
Under this structure setting, flexible substrates 111 are connected between two transmission elements 112, realize bending.The size of transmission element 112 can
To be made bigger, specifically, transmission element 112 at this time is only if it were not for covering bending region 11a can meet substrate 11
Foldable design need.For example, flexible substrates 111 and two transmission elements 112 are in rectangle, two transmission elements 112 are connected to
The opposite sides of flexible substrates 111, so that flexible substrates 111 can satisfy the rotation needs of the bending between two transmission elements 112, with
The folding for adapting to Folding screen needs.Transmission element 112 is capable of providing the light transmission needs of large format, to be provided in mobile terminal more
Under a screen when photosensitive element, this large format light transmission of transmission element 112 can reduce the design difficulty of photosensitive element under multiple screens,
Shielding lower photosensitive element can be rationally arranged in mobile terminal according to actual needs, as long as the transmission region of transmission element 112 can
Cover the lower photosensitive element of screen.
