In the conventional display device, especially in the portable display device, ink of a certain color, for example, black or white ink, is usually applied to the rim area of the cover glass for aesthetic reasons. However, since the sprayed ink layer generally has an uneven surface, when the packaging layer of the display device and the cover glass are bonded by the packaging adhesive, the packaging adhesive cannot completely cover the upper surface of the ink layer, so that a gap exists between the upper surface of the ink layer and the packaging layer of the display device. Due to the gap, the light emitted from the display device will propagate through reflection and/or refraction in the gap, thereby causing display unevenness of the display device under different viewing angles.

Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1A, which is a schematic structural view of an embodiment of a display device of the present application, fig. 1B is a cross-sectional view taken along a-a' in fig. 1A. It should be noted that, in order to make the drawings more clearly embody the invention of the present embodiment, the proportions of the components in fig. 1B are appropriately adjusted; some well-known layers in display devices are omitted in order not to obscure the focus of this embodiment.
Next, the present embodiment will be described with reference to fig. 1A and 1B.
The display device of the present embodiment includes a display area 110 and a bezel area surrounding the display area 110. The display area 110 may be used to realize display of a predetermined picture, and the bezel area is generally provided with a control circuit or the like that supplies a control signal to each display pixel within the display area 110.
The display device includes an encapsulation layer 120 and a cover glass 130 attached to the encapsulation layer 120.
The bezel region of the cover glass 130 is formed with an ink region 131 surrounding the display region 110, and the ink region 131 may include at least one ink layer. For example, when the desired ink is black, three ink layers may be sprayed to form the ink zones. The three ink layers may include, for example, two black ink layers and one white ink layer, wherein the white ink layer may be closest to the encapsulation layer of the display device. Due to process limitations in the formation of the ink layers, the upper surface of each ink layer is generally not planar, resulting in the upper surface of the ink areas also not being planar.
The display device further includes a transparent compensation layer 140, the transparent compensation layer 140 covers the display area and a portion of the bezel area of the cover glass 130, and the transparent compensation layer 140 covers a portion of the upper surface of the ink area 131.
In addition, in this embodiment, the display device may further include an encapsulation adhesive layer 150, and the encapsulation adhesive layer 150 may be formed, for example, in a frame region of the display device, and is used for bonding the encapsulation layer 120 and the cover glass 130. Alternatively, the encapsulation adhesive layer may also be formed between the encapsulation layer and the cover glass in a full-lamination manner, that is, the encapsulation adhesive layer may cover the display area and a portion of the frame area of the display device. The material of the encapsulating adhesive layer 150 may be, for example, a photo-curing adhesive, and the bonding between the encapsulating layer 120 and the cover glass 130 is achieved by first coating the photo-curing adhesive on an area to be bonded and then performing light irradiation (for example, ultraviolet irradiation) curing.
As can be seen from fig. 1B, in the display device of the present embodiment, since the transparent compensation layer 140 is disposed, the maximum height difference between the upper surface of the ink region 131 (i.e., the surface close to the encapsulation layer 120) and the encapsulation layer 120 can be reduced.
Specifically, after the transparent compensation layer 140 is disposed, since the transparent compensation layer 140 has a certain thickness, the maximum height difference between the upper surface of the transparent compensation layer 140 and the encapsulation layer 120 is reduced, so that the encapsulation glue layer 150 can be more filled in the gap between the transparent compensation layer 140, the ink region 131 and the encapsulation layer 120. Thus, when light emitted by the display device is emitted upwards from the lower side of the encapsulation layer 120, the gap between the ink region 131 and the encapsulation layer 120 is small, and the emitted light enters the gap less, so that the problem of display unevenness at different viewing angles due to the gap between the upper surface of the ink layer 131 and the encapsulation layer 120 is solved.
Please further refer to fig. 1A. In some alternative implementations, the maximum thickness a of the ink region 131 in the direction perpendicular to the cover glass 130 and the thickness b of the transparent compensation layer 140 in the direction perpendicular to the cover glass 130 satisfy: a-b is less than or equal to 20 mu m.
By setting the difference between a and b to be within 20 μm, it is possible to further ensure that the gap between the ink region 131 and the encapsulating layer 120 is small, thereby further improving the problem of display unevenness at different viewing angles due to the gap between the upper surface of the ink region 131 and the encapsulating layer 120.
In addition, in these alternative implementations, the thickness of the transparent compensation layer may be adjusted according to the maximum thickness of the ink region during the process of manufacturing the display device, so as to improve the problem of display non-uniformity to the maximum extent.
In some optional implementations, the transmittance t of the transparent compensation layer satisfies: t is more than or equal to 50 percent.
Since the transparent compensation layer covers the display area of the display device, the larger transmittance can reduce the influence of the transparent compensation layer on the display effect (e.g., display brightness, display contrast, etc.) of the display device as much as possible.
Referring to fig. 2A, which is a schematic structural view of another embodiment of the display device of the present application, fig. 2B is a cross-sectional view taken along B-B' in fig. 2A.
Similar to the embodiment shown in fig. 1A and 1B, the display device of the present embodiment also includes a display area 210 and a bezel area surrounding the display area 210. The display device includes an encapsulation layer 220 and a cover glass 230 attached to the encapsulation layer 220. The bezel region of the cover glass 230 is formed with an ink region 231 surrounding the display region 210, and the ink region 231 may include at least one ink layer. The display device further includes a transparent compensation layer 240, the transparent compensation layer 240 covers the display area and a portion of the bezel area of the cover glass 230, and the transparent compensation layer 240 covers a portion of the upper surface of the ink area 231.
Unlike the embodiment shown in fig. 1A and 1B, in the present embodiment, the transparent compensation layer 240 may be made of a transparent conductive material. Thus, the conductive transparent compensation layer 240 has electrostatic shielding properties, and thus can protect each electrical element of the display device to a certain extent, and effectively prevent electrostatic interference with the electrical elements.
In some optional implementations of this embodiment, the transparent conductive material for making the transparent compensation layer may be, for example, 3, 4-ethylenedioxythiophene monomer Polymer (PEDOT). Since both the 3-and 4-positions are substituted by pendant groups in PEDOT, polymerization can only occur at the 2-and 5-positions, and the resulting polymer is a linear (non-crosslinked), less conjugated polymer; the ether substituents, in turn, lower the oxidation potential of the monomers and polymers, making them more readily polymerizable, and more stable during redox (doping and dedoping) cycles. In addition, PEDOT also has the characteristics of high conductivity (more than 550 Siemens/cm can be reached) and high stability.
In some alternative implementations, in order to make the transparent compensation layer 240 of the present embodiment have better electrostatic shielding effect, a fixed voltage may be applied to the transparent compensation layer 240. For example, the transparent compensation layer 240 may be electrically connected to a power supply of the display device of the present embodiment, so that the transparent compensation layer 240 has a constant potential, and better performs an electrostatic shielding effect.
As further shown in fig. 2A and fig. 2B, in some alternative implementations of the present embodiment, the display device may further include a main control electrode 250. The encapsulation layer 220 and the cover glass 230 have through holes formed in the frame region for receiving the main control electrodes. The transparent compensation layer 240 is electrically connected to a power supply through the main control electrode 250.
The main control electrode 250 of the display device is typically used to wake up the display device from a standby state.
Fig. 2C is an equivalent circuit diagram of the main control electrode and its electrical connections with other electrical components of the display device. As can be seen in fig. 2C, the master electrode 250 may be equivalent to a normally open switch. One end of the normally open switch is electrically connected with a power supply, and the other end of the normally open switch can be electrically connected with a screen power supply port of the display device. When a user presses the main control electrode 250, the normally open switch is closed, the circuit is conducted, and power is supplied to the screen, so that the screen is awakened.
The display device of the embodiment can also reduce the gap between the upper surface of the ink layer and the packaging layer of the display device, thereby improving the problem of uneven display under different viewing angles caused by the gap between the upper surface of the ink layer and the packaging layer.
Further, since the transparent compensation layer 240 of this embodiment is made of a conductive material, an electrostatic protection effect can be further achieved on the display device, so that external static electricity is prevented from damaging a photoelectric device of the display device, and the service life of the display device is prolonged.
In some optional implementations of the display device of the present application, the display device further includes an optically transparent adhesive formed between the encapsulation layer and the cover glass for adhering the encapsulation layer and the cover glass; the optically transparent adhesive is formed in the display area and a portion of the frame area of the display device. The packaging layer and the cover plate glass are bonded by the optical transparent adhesive in a full-lamination mode, and the reliability of lamination between the packaging layer and the cover plate glass is higher. In addition, the transmittance of the optical transparent adhesive is high, so that the transmittance of the display screen is not affected.
In some alternative implementations, the display device of the present application may be a liquid crystal display device. The liquid crystal display device comprises an array substrate, a color film substrate and a liquid crystal layer formed between the array substrate and the color film substrate. The color film substrate can comprise the packaging layer.
As will be apparent to those skilled in the art, a thin film transistor array, a pixel electrode, and a common electrode layer are formed on an array substrate of a liquid crystal display device, and a color filter array is formed on a color filter substrate. These structures will not be described further in order not to obscure the focus of the present application.
In other alternative implementations, the display device of the present application may be an organic light emitting display device. The organic light emitting display device includes a substrate and an organic light emitting functional layer formed on the substrate. The packaging layer is attached to the substrate.
In some application scenarios of these alternative implementations, the organic light emitting display device may be a flexible display device. In these application scenarios, the substrate of the organic light emitting display device may be a flexible substrate, and the encapsulation layer of the organic light emitting display device may be a flexible encapsulation layer (e.g., the flexible encapsulation layer may be a thin film encapsulation layer).
Referring to fig. 3, a schematic flow chart of an embodiment of a method for manufacturing a display device according to the present application is shown.
The manufacturing method of the present embodiment can be used to manufacture the display device of each of the above embodiments.
The manufacturing method of the embodiment comprises the following steps:
in step 310, an ink area is formed on the frame area of the cover glass, wherein the ink area comprises at least one ink layer.
And 320, ink-jet printing is carried out on the cover plate glass to form a transparent compensation layer. The transparent compensation layer covers the display area and part of the frame area of the cover plate glass, and the transparent compensation layer covers part of the upper surface of the ink area.
In the manufacturing method of the display device of the embodiment, the transparent compensation layer covering a part of the upper surface of the ink region is formed on the cover glass, so that the height difference between the upper surface of the transparent compensation layer and the upper surface of the ink region can be reduced, and thus, when the cover glass and the packaging layer of the display device are packaged, the packaging glue can fill the gap between the cover glass and the packaging layer of the display device as much as possible, so that the problem of uneven display at different viewing angles caused by the gap between the upper surface of the ink layer and the packaging layer is solved.
In some optional implementation manners, the method for manufacturing the display device of the embodiment may further include:
And step 340, attaching the packaging layer and the cover glass.
And step 350, curing the optical transparent adhesive. Here, the optically transparent adhesive may be cured by ultraviolet irradiation, for example.
According to the display device and the manufacturing method thereof, the transparent compensation layer is added in the display device, the display area and part of the frame area of the cover plate glass are covered by the transparent compensation layer, and the transparent compensation layer covers one part of the upper surface of the ink area. The gap between the upper surface of the ink layer and the packaging layer of the display device can be reduced, so that the problem of uneven display under different visual angles caused by the gap between the upper surface of the ink layer and the packaging layer is solved.
It will be appreciated by those skilled in the art that the scope of the invention herein disclosed is not limited to the particular combination of features described above, but also encompasses other arrangements formed by any combination of the above features or their equivalents without departing from the inventive concept. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
