Abstract
The invention relates to a method for manufacturing an AMOLED display screen. The method includes the following steps that (1) a touch screen sensor is manufactured on a glass substrate, (2) low-temperature polycrystalline silicon is manufactured, (3) an organic light-emitting material is evaporated, (4) an AMOLED component is packaged, (5) an AMOLED touch screen is thinned, and packaging cover plate glass is thinned from 0.5 mm to 0.3 mm, (6) the large AMOLED touch screen is cut into small Cells, (7) the packaging cover plate glass of the AMOLED touch screen with the small Cells is reinforced, and (8) a modular procedure is carried out. According to the method, cost of the cover plate glass and one-shot gluing cost are reduced, the weight of the touch screen is reduced, and light transmittance is improved.
Description
Technical field
The present invention relates to technical field of flat panel display, relate to the touch screen technology of AMOLED display screen, be specifically related to a kind of touch-screen and be produced on AMOLED device LTPS(low temperature polycrystalline silicon) inner touch AMOLED display screen.
Background technology
AMOLED, as a kind of New Type Display Devices, has high chroma, high-contrast, wide visual angle, high brightness, self-luminous, fast response time, can realize the features such as flexible demonstration, has been acknowledged as flat panel display of future generation.AMOLED device architecture, substrate is take LTPS(low temperature polycrystalline silicon) be main flow, rear evaporation organic material, finally with cover plate by device package.AMOLED screen has been widely used in intelligent mobile display terminal, especially most widely used with touch-screen mobile phone, therefore touching technique is also very crucial.Tradition AMOLED touch screen device as shown in Figure 1; display screen comprises glass substrate and stacks gradually the low-temperature polycrystalline silicon layer of layout, luminous organic material layer and encapsulation cover plate, arranges touch panel sensor and on transducer, cover cover-plate glass with protection touch panel sensor on encapsulation cover plate.Its manufacturing process is by Sensor(touch panel sensor) be produced on AMOLED encapsulation cover plate, then the Cover Lens(cover-plate glass of fitting on transducer).This kind of touch screen device has following shortcoming: (1), integral device structure are partially thick, has substrate, encapsulation cover plate, cover-plate glass triplex glass; (2), device technology complexity, cost be high, adopts encapsulation, attaching process between AMOLED screen, encapsulation cover plate, cover-plate glass, flow process complexity, yield is low, and material cost is high; (3), between AMOLED screen and touch pad, there is space; Therefore cause readable decline, and can cause parallax.
Summary of the invention
The object of the invention is, in order to solve that existing touch AMOLED display screen structure is partially thick, manufacturing process is complicated and the shortcoming such as readable difference, to have proposed a kind of manufacture method of AMOLED display screen.
Technical scheme of the present invention is: a kind of manufacture method of AMOLED display screen, described AMOLED display screen comprises glass substrate and is covered in low-temperature polycrystalline silicon layer, organic luminous layer and the encapsulation cover plate on substrate, on described glass substrate, below low-temperature polycrystalline silicon layer, be furnished with touch panel sensor, it is characterized in that, the making of AMOLED display screen comprises the steps: that (1) makes touch panel sensor on glass substrate; (2), make low temperature polycrystalline silicon; (3), evaporation luminous organic material; (4), encapsulation AMOLED device; (5), AMOLED touch-screen attenuate, encapsulation cover plate glass is thinned to 0.3mm by 0.5mm; (6), open greatly AMOLED touch-screen and be cut into little Cell; (7), little Cell AMOLED touch-screen encapsulation cover plate is glass reinforced; (8), module operation.
Beneficial effect of the present invention: touch AMOLED display screen of the present invention is in-cell touch manner AMOLED device, and this device is more lightening, and material cost is lower.Specifically touch panel sensor is produced in AMOLED device low temperature polycrystalline silicon.On glass substrate, make touch panel sensor, then make low temperature polycrystalline silicon thereon, encapsulated after AMOLED device with encapsulation cover plate, encapsulation cover plate is further strengthened, therefore without the cover-plate glass of fitting again in the touch-screen the superiors.Have simple in structure frivolously, saved cover-plate glass cost and reduced the cost of once fitting, alleviated touch-screen weight and increased light transmittance.
Accompanying drawing explanation
Fig. 1 is existing touch AMOLED display screen layer structural representation;
Fig. 2 is touch AMOLED display screen layer structural representation of the present invention.
Embodiment
Following examples are that principle according to the present invention designs, and below in conjunction with accompanying drawing and following specific embodiment, the invention will be further elaborated.
As shown in Figure 2, the touch AMOLED display screen of one of the present embodiment, comprise glass substrate and be covered in low-temperature polycrystalline silicon layer, organic luminous layer and the encapsulation cover plate on substrate, it is characterized in that, on described glass substrate, below low-temperature polycrystalline silicon layer, being furnished with touch panel sensor.
Specific embodiment is: (1), on glass substrate, make touch panel sensor; (2), make low temperature polycrystalline silicon; (3), evaporation luminous organic material; (4), encapsulation AMOLED device; (5), AMOLED touch-screen attenuate, encapsulation cover plate glass is thinned to 0.3mm by 0.5mm; (6), open greatly AMOLED touch-screen and be cut into little Cell; (7), little Cell AMOLED touch-screen encapsulation cover plate is glass reinforced; (8), module operation.
The in-cell touch manner AMOLED device that the present embodiment is made is more lightening and material cost is lower.This AMOLED touch screen device is that touch panel sensor is produced in AMOLED device low temperature polycrystalline silicon, specifically on glass substrate, make touch panel sensor, make again low temperature polycrystalline silicon thereon, encapsulate after AMOLED device with encapsulation cover plate, encapsulation cover plate is further strengthened, therefore without the cover-plate glass of fitting again in the touch-screen the superiors.
Those of ordinary skill in the art will appreciate that, embodiment described here is in order to help reader understanding's principle of the present invention, should be understood to that protection scope of the present invention is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combinations that do not depart from essence of the present invention according to these technology enlightenments disclosed by the invention, and these distortion and combination are still in protection scope of the present invention.
Claims (1)
