[0002] With the development of science and technology, there are more and more intelligent products, and intelligent products can be seen everywhere in people's lives. Smart wearable products have been very popular in recent years. There are various styles of smart watches and bracelets, which are not only used as watches and sports equipment, but also have certain accessories.

[0003] These products generally use PMOLED screens, and desiccants are used in the production process of PMOLED screens.

Existing PMOLED screens generally have desiccants in the display area of ​​the display screen, and the desiccant is generally coated on the entire surface. Therefore, when observing the PMOLED screen from the back, only white desiccant can be seen, which makes the display screen of this structure only display on one side. Utility Model Content

Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] The utility model provides a PMOLED display screen capable of double-sided display, comprising a lower layer of glass and an upper layer of glass, wherein the upper layer of glass is arranged above the lower layer of glass, the lower layer of glass is longer than the upper layer of glass and extends outward to form a step, a driving IC and a driving FPC are bound to the upper surface of the lower layer of glass located at the step, a frame glue is arranged between the lower layer of glass and the upper layer of glass, a desiccant is silk-screened on the upper surface of the lower layer of glass, and the desiccant is located in a non-display area and close to the edge of the upper layer of glass.

[0034] Since the desiccant is screen-printed on the upper surface of the lower glass, and the desiccant is located in the non-display area and close to the edge of the upper glass, the size of industrial small-sized products such as wearable products is generally between 0.9 inches and 5 inches. At present, the performance of the desiccant is very good. The desiccant is screen-printed on the edge of the product, and its performance and reliability can fully meet customer requirements. And when the PMOLED display is viewed from the back, the desiccant will not affect the normal display. The PMOLED display is designed as a transparent screen so that the display content can be seen on both sides, thereby realizing double-sided display and improving the competitiveness of the product.

[0035] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0036] Example 1

[0037] See also Figures 1 to 6 , a PMOLED display screen capable of double-sided display provided by the utility model, comprising a lower glass 1 and an upper glass 2, the upper glass 2 being arranged above the lower glass 1, the lower glass 1 being longer than the upper glass 2 and extending outward to form a step, the upper surface of the lower glass 1 located at the step being bound with a driver IC 3 and a driver FPC 4, a frame glue 5 being arranged between the lower glass 1 and the upper glass 2, a desiccant 6 being screen-printed on the upper surface of the lower glass 1, and the desiccant 6 being located in the non-display area and close to the edge of the upper glass 2. Since the desiccant 6 is screen-printed on the upper surface of the lower glass 1, and the desiccant 6 is located in the non-display area and close to the edge of the upper glass 2, the size of industrial small-sized products such as wearable products is generally between 0.9 inches and 5 inches, the performance of the desiccant 6 is very good at present, and the desiccant 6 is screen-printed on the edge of the product, and its performance and reliability can fully meet customer requirements. Furthermore, the desiccant 6 will not affect the normal display when the PMOLED display screen is viewed from the back. The PMOLED display screen is designed as a transparent screen so that the display content can be seen from both the front and back sides, thereby achieving double-sided display and improving the competitiveness of the product.

[0038] Furthermore, the desiccant 6 is located above, below, on the left or on the right of the display area, that is, the desiccant 6 can be screen-printed on one side to achieve the drying effect, thereby reducing product costs.

[0039] Furthermore, the desiccant 6 is arranged around the display area, that is, the four sides of the desiccant 6 are all silk-screened, making the product more beautiful.

[0040] Furthermore, the desiccant 6 is packaged inside the sealant 5 .

[0041] Example 2

[0042] See also Figure 7As a further optimization scheme of Example 1, in this embodiment, an insulating shielding integrated layer 7 is attached to the driver IC3 and the driver FPC4. The insulating shielding integrated layer 7 includes an insulating paper 71 and a conductive shielding material 72. The conductive shielding material 72 is arranged above the insulating paper 71. The area of ​​the insulating paper 71 is smaller than the area of ​​the conductive shielding material 72. The insulating paper 71 can completely cover the driver IC3 and partially cover the driver FPC4. The conductive shielding material 72 has a through hole 73 at the edge of the insulating paper 71. The through hole 73 is located in the area where no components are provided. Since the conductive shielding material 72 has a through hole 73 at the edge of the insulating paper 71, the operator can see the edge of the insulating paper 71, so that the operator can judge the position of the insulating paper 71 when attaching, so as to avoid being attached to the driver IC3 and the driver FPC4 in an offset manner or not being attached, thereby preventing a short circuit and avoiding economic losses.

[0043] Furthermore, the through hole 73 is a circular hole, and one end of the opening waste is connected to the conductive shielding material 72. So that the position of the insulating paper 71 can still be observed by breaking the opening waste at the circular hole, and the opening waste is covered back after being pasted, so as to avoid the opening being unable to ensure conductive shielding.

[0044] Furthermore, a double-sided tape is provided at the bottom of the waste material with holes, and the waste material with holes is pasted back by the double-sided tape to avoid failure to ensure conductive shielding at the holes.

[0045] See also Figure 8 Furthermore, one side of the insulating paper 71 extends beyond the conductive shielding material 72, so that the operator can judge the specific position of the insulating paper 71 through the insulating paper 71 extending beyond the conductive shielding material 72, thereby avoiding biased attachment or failure to attach to the driver IC3 and the driver FPC4, thereby preventing a short circuit and avoiding economic losses.

[0046] Furthermore, the conductive shielding material is conductive paper or copper foil, which can form a conductive shielding effect.

[0047] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
