Description

Technical Field

[0001] The utility model relates to the technical field of display, and more specifically to an AMOLED smart watch. Background Art

[0002] Outdoor sports AMOLED smart watches are used outdoors. Due to the influence of strong external light, the brightness of the AMOLED needs to be adjusted to a higher level to clearly see the information on the smart watch. The brightness is about 800nits to 1000nits. In this way, the surface of the AMOLED will heat up seriously during long-term use. In order to prevent the AMOLED from working for a long time under high temperature and accelerate the aging of the AMOLED, the heat dissipation problem must be considered. The lower substrate of the traditional AMOLED display module is provided with foam. The function of the foam is to prevent external light from entering from the back of the AMOLED, but the existence of the foam is not conducive to the heat dissipation of the AMOLED.

[0031] The foam in the traditional structure is removed, and a black infrared radiation heat dissipation coating is set on the lower surface of the lower substrate. The main components of the infrared radiation heat dissipation coating are usually graphene and carbon nanotubes, which are then made with a resin carrier through a special grinding and dispersion process. Graphene with a low number of layers and a small diameter in a sheet structure is selected, and then compounded with hexagonal carbon nanotubes. The characteristics of graphene and carbon nanotubes with high thermal radiation and thermal infrared emissivity are used to make the coating present a macroscopic smooth and microscopic wavy radiation structure unit.

[0032] 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.

[0033] Example 1

[0034] See also Figure 1, an AMOLED smart watch provided by the utility model, comprising a lower substrate 1, an upper substrate 2 and an insulating layer 3, the upper substrate 2 is arranged above the lower substrate 1, an ITO circuit pattern 4 is arranged on the upper surface of the upper substrate 2, an insulating layer 3 is arranged above the upper substrate 2, a black infrared radiation heat dissipation coating 5 surrounding the display area is arranged on the lower surface of the lower substrate 1, and the coating shape of the black infrared radiation heat dissipation coating 5 is a square. The foam in the traditional structure is removed, and the black infrared radiation heat dissipation coating 5 is arranged on the lower surface of the lower substrate 1 instead. The main components of the infrared radiation heat dissipation coating 5 are usually graphene and carbon nanotubes, which are then prepared by a special grinding and dispersion process with a resin carrier. Selecting graphene with a low number of layers and a small sheet diameter in a sheet structure, and then compounding it with hexagonal carbon nanotubes, using the characteristics of graphene and carbon nanotubes having high thermal radiation and thermal infrared emissivity, the coating presents a macroscopically smooth and microscopically wavy radiation structure unit. Such a structure can greatly increase the heat dissipation area and conductivity, significantly improve the effect of heat exchange, and quickly dissipate the heat of the heating element to the surroundings to achieve a cooling effect and avoid accelerated aging of AMOLED. The infrared radiation heat dissipation coating 5 is beneficial to the heat dissipation of the AMOLED display module, and the infrared radiation coating is a black coating, which is also beneficial to prevent the outside light from entering from the back of the AMOLED display module.

[0035] Furthermore, the thickness of the black infrared radiation heat dissipation coating 5 is nanometer-level, while the thickness of the foam is generally 0.1 mm, thereby reducing the thickness of the AMOLED smart watch, reducing costs while also making the product thinner.

[0036] Example 2

[0037] See also Figure 2 and Figure 3 As a further optimization scheme of Example 1, in this embodiment, the upper surface of the lower substrate 1 is bound with FPC6. The FPC6 includes a substrate layer 61, a circuit layer 62 arranged on the upper surface of the substrate layer 61, and a metal heat dissipation layer 63 arranged on the lower surface of the substrate layer 61. The arrangement method can be that the circuit layer 62 and the metal heat dissipation layer 63 are respectively attached to the substrate layer 61 by double-sided adhesive. Since the thickness of the substrate layer 61 is relatively thin, the heat on the FPC6 can be diffused to the metal heat dissipation layer 63 through the substrate layer 61. The metal heat dissipation layer 63 can effectively increase the heat dissipation area of ​​the FPC6 and play a role in uniform heat dissipation, thereby improving the heat dissipation efficiency of the FPC6. The substrate layer 61 can be any one of polyimide, polyester, polysulfone or polytetrafluoroethylene, the double-sided adhesive is any one of an acrylic adhesive layer or an epoxy resin adhesive layer, and the metal heat dissipation layer 63 can be a copper foil layer.

[0038] Furthermore, the FPC 6 also includes at least one through-hole 64 penetrating the substrate layer 61, the circuit layer 62 and the metal heat dissipation layer 63, and the inner wall of the through-hole 64 is provided with a heat-conducting layer in contact with the circuit layer 62 and the metal heat dissipation layer 63. By utilizing the good thermal conductivity of the through-hole 64, the circuit layer 62 and the metal heat dissipation layer 63 on both sides of the substrate layer 61 can be electrically connected to play a good thermal conductivity function, and the thermal conductive layer can provide a thermal conductive function to achieve a good heat dissipation effect. Among them, the thermal conductive layer can be a copper glue conductive ink layer.

[0039] Furthermore, a heat conductor connected to an external heat-conducting structure is disposed in the through hole 64. The heat conductor is connected to the external heat-conducting structure from one side of the circuit layer 62 and is also in contact with the heat-conducting layer in the through hole 64, so that the circuit layer 62 and the metal heat dissipation layer 63 can be connected to the external heat-conducting structure through the through hole 64, so that the heat in the FPC 6 can be diffused to the external heat-conducting structure through the heat conductor in the through hole 64, so as to further improve the heat dissipation efficiency of the FPC 6. Preferably, in order to enable the through hole 64 to be connected to the external heat-conducting structure, the through hole 64 is disposed at the edge of the FPC 6.

[0040] Example 3

[0041] See also Figure 4 and Figure 5 As a further optimization scheme of Example 1, in this embodiment, please refer to Figure 4 As a further optimization scheme of Example 1, in this embodiment, a cover plate 7 is arranged above the insulating layer 3, and the cover plate 7 includes a visible area and a non-visible area. The lower surface of the cover plate 7 located in the non-visible area is provided with an ink layer 8, and the lower surface of the cover plate 7 located in the visible area is coated with an optical glue 9, and the optical glue 9 extends and covers the lower surface of the ink layer 8 close to the visible area. The ink layer 8 away from the visible area is not covered by the optical glue 9 and forms an empty layer area, and the lower surface of the optical glue 9 forms a smooth surface. Since the optical glue 9 is directly coated on the lower surface of the cover plate 7 and extends to the lower surface of the ink layer 8, instead of being directly attached to the lower surface of the cover plate 7 by using an optical glue 9 tape as in the traditional technology, the lower surface of the optical glue 9 can be formed into a smooth surface, and there is no height difference on the lower surface of the optical glue 9, so that the cover plate 7 will not generate bubbles and edge yellow spots when it is attached, avoiding display abnormalities, thereby reducing the probability of defective products, and the production and manufacturing costs will also be greatly reduced, thereby improving the product competitiveness, thereby meeting the growing quality requirements of enterprises.

[0042] Furthermore, the width of the optical adhesive 9 extending and covering the ink layer 8 is 0.6 mm to 0.8 mm.

[0043] Further, the thickness of the ink layer 8 is 8 μm to 15 μm.

[0044] Furthermore, the thickness of the optical adhesive 9 is 50 μm to 100 μm.
