There is OLED display screen and the manufacture method thereof of touch function

Technical field

The present invention relates to organic luminescent device field, specifically a kind of OLED display screen and manufacture method thereof with touch function.

Background technology

OLED (Organic Light Emitting Diode, English full name is Organic Light-Emitting Diode) display screen, its display mode and traditional LCD (liquid crystal display, English full name is Liquid CrystalDisplay) display mode difference, without the need to backlight, adopt very thin coating of organic material and glass substrate, when have electric current by time, these organic materials will be luminous.Therefore, the characteristic of OLED is that oneself is luminous, unlike TFT (Thin Film Transistor (TFT), English full name is Thin FilmTransistor) LCD needs backlight, and therefore visibility and brightness are all high, are secondly that voltage requirements is low and power saving efficiency is high, add that reaction is fast, lightweight, thickness is thin, simple structure, cost is low, is regarded as one of product of 21 century most future.

In order to meet the needs of touch control, touch screen function is often needed to be integrated in OLED display screen, No. CN101876866A patent document discloses a kind of preparation method with the organic luminescent device of touch-screen, directly touch screen body is directly installed on the OLED base plate for packaging of display device, then the substrate with touch-screen is fitted with the OLED cover plate contraposition of the OLED body made, substrate with touch-screen is combined with cover plate, seal, combined by touch-screen and OLED encapsulation cover plate, the OLED structure of existing band touch-screen is simplified, eliminate touch screen base plate, touch-screen cover plate, and simplify existing technique.

In above-mentioned patent documentation, touch screen body is integrated in OLED encapsulation cover plate inside surface and can may damages organic material layer: in display screen production run; the upper surface part subregion evaporation organic material layer of substrate body; be not damaged for protecting this organic material layer; conventional technique erodes away a cavity in cover plate and the one side of described substrate contacts and the lower surface respective regions of cover plate to hold above-mentioned organic material layer; make there is gap between the cover plate in the display screen after sealing and organic material layer, ensure not scratching organic material layer.Touch cover plate if used, conveniently technique needs also to erode away a cavity touching cover plate lower surface respective regions, covers the lower surface of whole cover plate, will inevitably damage touch screen body layer like this owing to touching body layer; If do not erode away the corresponding cavity holding organic material layer, then, when display screen moves, substrate and cover plate may produce relative displacement, and touch screen body meeting scratching, to organic material layer, causes the damage of organic material layer.The possible solution substituted first erodes away cavity at the lower surface of cover plate, integrated touch screen body in this cavity, this cavity also possesses the above-mentioned organic material layer of sufficient space simultaneously, this sampling technology is unfavorable for suitability for industrialized production again, reason be existing input suitability for industrialized production all in one plane prepare P.e.c., above-mentioned its circuit of touch screen body integrated in cavity and extraction electrode are not in a plane, the technology of existing P.e.c. can not be used, complexity and the production cost of manufacture can be increased, can not suitability for industrialized production be realized.

Summary of the invention

For this reason, to be solved by this invention be the organic light emitting diode device of existing band touch-screen be integrated in that OLED encapsulation cover plate inside surface brings due to touch screen body damage organic material layer or can not the technical matters of suitability for industrialized production, a kind of OLED display screen and the manufacture method thereof with touch function are provided.
