Description
Technical field
The present invention relates to a kind of touch-screen, more particularly to a kind of touch-screen that can reduce oled panel reflectivity.
Background technology
Current mobile phone faceplate is visual poor under high light, and this is primarily due to reflection of the panel surface to sunshine
Cause more by force.Relative to LCD, oled panel brightness is relatively low, in order to improve the contrast under high light, it is necessary to panel has
There is lower reflectivity.Refering to shown in Fig. 1, the main module of current oled panel includes touch-screen 2 (Touch Panel, abbreviation
TP), polaroid 22 (Polarizer, abbreviation POL) and luminescent layer 23 (Organic Light Emitting Diode, abbreviation
OLED), the ambient light of luminescent layer 23 (OLED) surface reflection is can absorb using polaroid 22, therefore panel reflectivity is main
Determined by the degree of polarization of touch-screen 2 (TP) reflectivity of light and polaroid 22 (POL) to external world.And the light to external world of touch screen 2
It is that the capacitive sensing circuit layer 21 included by its module internal is caused to reflect some.
TP species widely used at present mainly includes GG2, GG, OGS, GFF, G1F, GF2, GF1, wherein GG2, GG,
GFF, GF2, GF1 are constructed using patch and mode, i.e., will be deposited with using optical cement (Optical ClearAdhesive, abbreviation OCA)
The film of capacitive sensing circuit and cover-plate glass 24 paste and together with.The patch and mode of the module of traditional oled panel are in envelope
Fit POL and TP successively on the OLED luminescent layer 23 for installing.
Using said structure, TP internal capacitance sensor circuits structure can cause certain reflection to incident ambient light, should
Reflected light is about 1.5%, and this causes that contrast of the panel under external environmental light declines, and it occupies in whole panel reflectivity
Ratio very high, the reflection for reducing the part can effectively improve visuality of the panel under high light.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of reflection that can effectively reduce oled panel light to external world,
Improve the touch-screen of contrast of the panel under high light and visuality.
To realize above-mentioned technique effect, the invention discloses a kind of touch-screen, the touch-screen is fitted on oled panel,
The touch-screen includes a capacitive sensing circuit layer and the cover-plate glass being packaged on the capacitive sensing circuit layer, the electricity
Hold and be provided with one layer of polaroid between sensor circuit layer and the cover-plate glass.
Further improvement of the invention is that the cover-plate glass is fitted on the polaroid by Optical transparent adhesive.
Of the invention further improvement be, the polaroid is a rotatory polarization piece, including a linear polarizer and one 1/4 ripples
Piece, the lower surface of the polaroid is attached with an adhesive-layer, and fits in the capacitive sensing circuit by the adhesive-layer
On layer.
Further improvement of the invention is that the touch-screen is fitted on the oled panel by Optical transparent adhesive.
The present invention makes it have following beneficial effect as a result of above technical scheme：By the electric capacity in touch-screen
One layer of polaroid is inserted between sensor circuit layer and cover-plate glass, can incident light that effectively Absorption Capacitance sensor circuit layer is caused
Reflection, reduces the reflection of oled panel light to external world, improve contrast of the panel under high light with it is visual.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further detailed explanation.
Refering to shown in Fig. 2, the invention discloses a kind of touch-screen 1, the touch-screen 1 is fitted on oled panel 11, is touched
Screen 1 includes a capacitive sensing circuit layer 12 and the cover-plate glass 14 being packaged on capacitive sensing circuit layer 12, wherein, electric capacity sense
Answer and one layer of polaroid 13 is provided between circuit layer 12 and cover-plate glass 14.Cover-plate glass 14 fits in polarisation by Optical transparent adhesive
On piece 13.
Polaroid 13 (Polarizer, abbreviation POL) is a rotatory polarization piece, including a linear polarizer 131 and a quarter wave plate
132, its structure is as shown in Figure 3.The lower surface of polaroid 13 is attached with an adhesive-layer 130 (Adhesive Layer), by this
Adhesive-layer 130 fits in the upper surface of capacitive sensing circuit layer 12, is caused for Absorption Capacitance sensor circuit 12 internal circuit of layer
Incident light reflection.Refering to shown in Fig. 4, the principle that polaroid 13 absorbs reflected light is as follows：
Quarter wave plate 132 (quarter-wave plate) is certain thickness birefringence monocrystalline thin slice, when light normal incidence
Through when, the position difference between ordinary light (o light) and non-ordinary light (e light) is equal to pi/2 or its odd-multiple, and such chip is referred to as four
/ mono- wave plate or quarter wave plate.When linearly polarized light vertical incidence quarter wave plate 132, and light polarization and the axial plane of mica
When (vertical natural parting plane) is into θ=45 °, emergent light is circularly polarized light.Circularly polarized light by capacitive sensing circuit layer 12 inside
After circuit reflection, with π phase delays, so the direction of rotation of its circular polarization changes, then turn into inclined by quarter-wave plate
Shake the direction linearly polarized light vertical with linear polarizer polarization direction, therefore the reflected light can be absorbed by the polarizer, and will not go out from panel
Penetrate.Therefore polaroid POL is positioned over the top of capacitive sensing circuit layer 12, may be such that TP internal capacitances sensor circuit layer 12 is caused
The reflection of incident light absorbed by polaroid POL, can effectively reduce the reflection of oled panel light to external world, improve panel in high light
Under contrast with it is visual.The upper surface of polaroid 13 further fits in cover-plate glass 14 by Optical transparent adhesive.
The present invention is described in detail above in association with accompanying drawing embodiment, those skilled in the art can be according to upper
State it is bright the present invention is made many variations example.Thus, some of embodiment details should not constitute limitation of the invention, this
The scope that invention will be defined using appended claims is used as protection scope of the present invention.
