Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.
In order to better understand the present invention, a display device and an electronic apparatus according to embodiments of the present invention are described in detail below with reference to fig. 1 to 9.
Referring to fig. 1 to fig. 2 together, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the invention; FIG. 2 is a schematic cross-sectional view at A-A of FIG. 1, in accordance with one embodiment of the present invention.
An embodiment of the present invention provides a display device including: a substrate 1; an optical functional layer 2 provided on one side of the substrate 1; the optical adhesive layer 3 is arranged on one side of the optical functional layer 2, which is away from the substrate 1, and the optical adhesive layer 3 is provided with a first side surface C1; the flexible cover plate 4 is arranged on one side of the optical adhesive layer 3, which is away from the substrate 1, and the flexible cover plate 4 comprises an extension part 41 which extends outwards relative to the optical adhesive layer 3, wherein the extension part 41 is provided with a second side surface C2 and a first surface P1 facing the substrate 1; the water-oxygen barrier 5 is provided at least on the second side surface C2 side and the first surface P1 side, and the water-oxygen barrier 5 is in contact with the first side surface C1.
The display device provided by the embodiment of the invention comprises the substrate 1, the optical functional layer 2, the optical adhesive layer 3, the flexible cover plate 4 and the water-oxygen blocking part 5, wherein the water-oxygen blocking part 5 is arranged to block external water oxygen from entering the display device from the edge of the flexible cover plate 4, namely the second side surface C2 side of the extension part 41, and the water-oxygen blocking part 5 is arranged on the first surface P1 to block water oxygen from entering the optical adhesive layer 3 from the extension part 41 and between the optical adhesive layer 3 and the flexible cover plate 4, and also can prevent the water oxygen from diffusing downwards to damage the optical functional layer 2, namely the adverse effect of the water oxygen on the optical adhesive layer 3 or the optical functional layer 2 can be prevented, so that the reliability of the display device is improved.
The display device provided by the embodiment of the invention can be a flexible display device, and can be in a folding or winding drum and other structural forms, and the flexible cover plate 4 in the embodiment of the invention can be made of CPI (Colorless Polyimide, transparent polyimide film), PET (Polyethylene Terephthalate ) and other transparent, soft and foldable materials so as to realize the flexible folding of the cover plate, thereby being convenient for being applied to the foldable display device.
For example, in the embodiment of the present invention, the flexible cover 4 may be made of CPI, but because of the limited ability of CPI to block water vapor and oxygen, under the environment reliability test condition, water oxygen easily enters the module from the display device portion and the extension portion 41 of the flexible cover 4, so that the color of the optical functional layer 2 fades and reacts with the components of the optical adhesive layer 3, and the bending easily causes the module failure problem such as peeling.
In order to solve the above-mentioned problems, the embodiment of the present invention improves the reliability of the display device by providing the water-oxygen barrier portion 5 on the first surface P1 and the second side C2 of the extension portion 41 where the flexible cover 4 extends outwards with respect to the optical adhesive layer 3, so as to prevent external water oxygen from entering the display device from the extension portion 41 itself or the second side C2 of the extension portion 41.
Wherein, the substrate 1 may be a hard substrate such as a glass substrate; the flexible substrate can also be made of transparent polyimide, polystyrene, polyethylene terephthalate, parylene, polyethersulfone or polyethylene naphthalate. The substrate 1 is mainly used for supporting devices arranged thereon. In the present embodiment, considering that the display device employs the flexible cover plate 4, the substrate 1 may correspondingly employ a flexible substrate.
Alternatively, the optical functional layer 2 may include a film layer for treating the light emitted from the display device, such as a polarizer.
For example, the optical functional layer 2 includes a polarizer including a third side C3 connected to the first side C1, and the water-oxygen barrier 5 at least partially covers the third side C3.
In this embodiment, the flexible cover 4 includes an extension portion 41 extending outwards relative to the optical adhesive layer 3, and the extension portion 41 extending outwards relative to the optical adhesive layer 3 may be understood as that the extension portion 41 extends along a direction parallel to a plane where the substrate 1 is located, and away from the center of the flexible cover 4, that is, the portion of the flexible cover 4 that does not cover the optical adhesive layer 3 and extends outwards relative to the optical adhesive layer 3 may be a planar structure, or may be a curved structure according to practical situations, and is not limited in particular.
Optionally, the display device provided in the embodiment of the present invention further includes an array layer 7 and a display layer 6 disposed between the substrate 1 and the optical functional layer 2.
For example, the array layer 7 includes a pixel circuit (not shown in the figure), and the display layer 6 includes a first electrode layer (not shown in the figure), a light emitting layer (not shown in the figure), and a second electrode layer (not shown in the figure) which are stacked. Optionally, the light emitting layer includes one or more of an electron injection layer, an electron transport layer, a light emitting material layer, a hole blocking layer, an electron blocking layer, a hole transport layer, and a hole injection layer. The specific type of the light-emitting layer may be selected, and is not particularly limited. The electron injection layer, the electron transport layer, and the hole blocking layer may be disposed between the second electrode layer and the light emitting material layer. The electron blocking layer, the hole transporting layer, and the hole injecting layer may be disposed between the first electrode layer and the light emitting material layer.
The pixel circuit includes a thin film transistor including an active layer, a gate electrode, a source electrode, a drain electrode, a source electrode, and a gate electrode, and a material of the thin film transistor may include one or more combinations of molybdenum, titanium, aluminum, copper, and the like. The gate electrode of the thin film transistor is generally used for receiving a control signal, so that the thin film transistor is turned on or off under the control of the control signal. One of the source electrode and the drain electrode of the thin film transistor is connected to the first electrode layer to control normal light emission of the light emitting layer.
Optionally, a touch layer (not shown) and a packaging layer (not shown) may be disposed between the display layer 6 and the optical functional layer 2, and the film layer is not particularly limited. The encapsulation layer can be specifically selected from organic encapsulation layer or inorganic-organic-inorganic composite encapsulation layer. The organic material for preparing the packaging layer has the advantages that the flatness is good, planarization can be realized, and the inorganic film layer can be grown later by a method such as chemical vapor deposition, physical vapor deposition or atomic layer deposition; the organic material with larger thickness can be prepared by the prior art, and the organic material has better bending resistance.
The packaging layer can be an organic packaging layer or an inorganic-organic-inorganic composite packaging layer and other structures.
Specifically, the packaging layer may be formed by the following combinations: silicon nitride-organic material-silicon nitride; alumina + silicon nitride-organic material-silicon nitride + alumina; silicon oxide + silicon nitride-organic material-silicon nitride + silicon oxide. Of course, several layers of inorganic material may be stacked.
