[0024] like Figure 1As shown, a photosensitive integrated structure of an ONCELLAMOLED display module includes: an ONCELLAMOLED display module 1 includes an insulating layer 11, an ITO sensing pattern layer 13, an encapsulation glass 14, a color filter 15 and an LTPS glass 16, a sensing layer 12 is arranged between the bottom of the insulating layer 11 and the ITO sensing pattern layer 13; the sensing layer 12 includes a transparent glass, the transparent glass is arranged at the bottom of the insulating layer 11, and an ambient light sensor, a proximity sensor and an analog generator circuit are arranged on the transparent glass. It should be noted that the advantage of this design is that the cost of AMOLED is relatively high from a cost point of view, and the AMOLED will be more complicated from a technical point of view, so it is necessary to separate the insulating layer 11 of the ambient light sensor and the proximity sensor from the AMOLED, so that when the AMOLED is damaged, we can not add the insulating layer 11 that fits the ambient light sensor and the proximity sensor.
[0025] like Figure 1 As shown, in one embodiment, the stacking method in the ONCELLAMOLED display module 1 is stacked in the order of the insulating layer 11, the sensing layer 12, the ITO sensing pattern layer 13, the encapsulation glass 14, the color filter 15 and the LTPS glass 16. It should be noted that the ONCELLAMOLED display module 1 is also provided with a display FPC, a touch FPC and an IC.
[0026] like Figure 1 As shown, in one embodiment, a protective film is provided on the surface of the insulating layer 11, and the light transmittance of the protective film is 90%. It should be noted that the protective film is mainly used to protect the surface of the insulating layer 11 from dust.
[0027] like Figure 1 As shown, in one embodiment, the insulating layer 11 and the transparent glass in the sensing layer 12 are integrally formed. The ambient light sensor, proximity sensor and analog generator circuit diagram on the sensing layer 12 are all set by sputtering ITO to etch the wiring. It should be noted that this design allows the insulating layer 11 and the sensing layer 12 to become a whole.
[0028] like Figure 1 As shown, in one embodiment, the ITO sensing pattern layer 13 and the display FPC are electrically connected to each other, and the sensing layer 12 and the display FPC are electrically connected to each other.
[0029] like Figure 1 As shown, in one embodiment, an optical glue is provided between the color filter 15 and the encapsulation glass 14, and the light transmittance of the optical glue is 95%. It should be noted that the optical glue can not only be used to connect the color filter 15 and the encapsulation glass 14, but also play a role in protecting the display module.
[0030] like Figure 1 As shown, in one embodiment, the shape and size of the transparent glass front of the sensing layer 12 are adapted to the shape and size of the front of the insulating layer 11 and the ITO sensing pattern layer 13. It should be noted that the display area of the ONCELLAMOLED display module 1 can be controlled by sensing to the greatest extent.
[0031] like Figure 1 As shown, in one embodiment, a glass protective layer is provided on the surface of the insulating layer 11, and the edges of the glass protective layer are polished to be smooth. It should be noted that this design can enhance the safety of the display module.
[0032] like Figure 1 As shown in one embodiment, the shape of the ONCELL AMOLED display module 1 is a conventional circle or square. It should be noted that the actual size and shape of the ONCELL AMOLED display module 1 need to be designed according to production needs.
[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
