In order to realize the purpose, it can be formed by vapor deposition, etching mode on the upper surface of lower layer's light penetrating panel 2 20
The coating of pixel layer 3 and wiring layer 4.Wherein, AMOLED (full name in English may be used in pixel layer 3：Active-matrix
Organic light emitting diode, Chinese：Active matrix organic light-emitting diode), with wide colour gamut, height
The technical advantages such as contrast, high outdoor readable, low energy consumption are the emphasis of display screen technology future research and development.The material of wiring layer 4
ITO (full name in English may be used：Indium Tin Oxide, Chinese：Tin indium oxide), ITO is a kind of N-type oxide half
Conductor-tin indium oxide has good electric conductivity and the transparency, is highly suitable as the wiring material of pixel layer 3.It is plated being formed
When layer, the one side edge in pixel layer 3 can be arranged in wiring layer 4, can also be centered around each side of 3 surrounding of pixel layer simultaneously
Edge, and formed and be electrically connected between wiring layer 4 and pixel layer 3.
After pixel layer 3 and wiring layer 4 are provided with, in order to be protected to pixel layer 3, steam oxidation pixel layer is prevented
3, it needs the remaining surface in pixel layer 3 in addition to lower surface to form light transmission protective layer 6 and is covered (referring to Fig. 3).In order not to
The display function of pixel layer 3, light transmission protective layer 6 is interfered to need to use light-transmitting materials.6 one side of light transmission protective layer will play isolation
On the other hand the effect of steam will also have enough bonding strengths with pixel layer 3.In the present embodiment, the material of light transmission protective layer 6
Choosing of fine quality uses silicon nitride, silicon nitride that can be formed in the surface of pixel layer 3 in a manner of coating, so that one layer of formation is secured, causes
Close protective layer, also, due to silicon nitride light transmission itself, the display of pixel layer 3 will not be impacted.
It is in status of electrically connecting in the edge of pixel layer 3 and the two since wiring layer 4 is arranged, thus while wiring layer 4 is simultaneously
Light transmission protective layer 6 is not needed to be isolated steam, but for the considerations of simplifying technique, it can be together when forming light transmission protective layer 6
By remaining surface covering of the wiring layer 4 in addition to lower surface.
In the present embodiment, the region of the covering of light transmission protective layer 6 pixel layer 3 is named as pixel layer covering part 60, and light transmission is protected

Plate 2, pixel layer 3, wiring layer 4 and light transmission protective layer 6 are formed by overall structure and bond together, and need to use optical adhesive layer
7 realize.
Optical adhesive layer 7 is that have stronger viscosity and transparent glue-line, is covered wiring layer 4 or light transmission protective layer 6,
Closely to bond together with wiring layer 4 or light transmission protective layer 6.Optical adhesive layer 7 needs enough bond areas that can just gather around
There are enough adhesive strengths, and in display screen, main region is the pixel layer covering part 60 for covering pixel layer 3, therefore
Optical adhesive layer 7 needs the subregion of at least covering pixel layer covering part 60, to obtain enough bond areas.For example, optics
Glue-line 7 can cover the larger area of 4 covering part of pixel layer, 60 surrounding simultaneously, and be stayed in the central area of pixel layer covering part 60
Go out some spare areas.Or optical adhesive layer 7 can also reserve some spare areas in certain side of pixel layer covering part 60, and
Other sides all cover optical adhesive layer 7.Spare area can also be located at the corner of pixel layer covering part 60 or other any positions,
As long as ensureing that optical adhesive layer 7 possesses enough bond areas to ensure adhesive strength.Since optical adhesive layer 7 is transparent in itself
, therefore the display of pixel layer 3 will not be influenced.
However, due to the refraction of light, will appear with the image for not penetrating optical adhesive layer 7 through the image of optical adhesive layer 7
Vision difference influences user experience, and therefore, optical adhesive layer 7 is preferably able to the whole region of covering pixel layer covering part 60, in this way
On the one hand vision difference can be eliminated, the bond area of optical adhesive layer 7 on the other hand can be also expanded, improves adhesive strength.
In addition to this, optical adhesive layer 7 can also cover a part of region of wiring layer 4 or wiring layer covering part 62, with
Further promote bond area and adhesive strength.Also, relative to one of only covering wiring layer 4 or wiring layer covering part 62
Subregion, the whole region for covering wiring layer 4 or wiring layer covering part 62 is easier in production technology, therefore recommends to adopt
With.
Since there are differences in height for 3 self structure of pixel layer, while there is also differences in height between pixel layer 3 and wiring layer 4
It is different, therefore the surface for being formed by light transmission protective layer 6 can also have many height and rise and fall.Therefore in order to enable optical adhesive layer 7
It is fully in close contact with light transmission protective layer 6, forms optical adhesive layer 7 preferably with liquid optical cement, utilize the good of liquid optical cement
Good mobility can be such that optical adhesive layer 7 and the surface of light transmission protective layer 6 comes into full contact with, and be formed simultaneously smooth optical adhesive layer 7
Upper surface 70.Certainly, for the ease of operation, can utilize liquid optical cement directly by the upper surface 20 of lower layer's light penetrating panel 2 with
And the exposed face of light transmission protective layer 6 all coverings (referring to Fig. 4).
The upper surface 70 of the lower surface 10 of upper layer light penetrating panel 1 and optical adhesive layer 7 is bonded together (referring to figure later
