Embodiments of the present invention relate to a display device and a manufacturing method thereof.
Display devices mainly include liquid crystal display devices and Organic Light-Emitting Diode (OLED) display devices. In the practical application, light emitting surface of a conventional display device tends to experience badness such as glare due to the influence of light from external environment, which would have a strong impact on the user's viewing experience. In order to overcome various optical badness including glare, various optical functional layers are generally formed on a surface of a display device.
Particularly, for a liquid crystal display device, as the core component for the liquid crystal display device, the liquid crystal panel mainly includes a color filter substrate and a Thin Film Transistor (TFT) array substrate assembled to form a cell with each other with a liquid crystal layer formed of liquid crystal material therebetween. Generally, under the action of a voltage, the liquid crystal layer can only rotate polarized light with a certain polarization angle, therefore, in prior art, an upper polarizer sheet and a bottom polarizer sheet are generally attached to the surfaces of upper and bottom glass substrates of the liquid crystal panel. In order to overcome various optical badness including glare, polarizer sheets are generally subjected to different kinds of surface treatments to form optical functional layers with different functions. The specific structure of the polarizer sheet 1 is illustrated in
An embodiment of the invention provides a display device, comprising a display panel provided with a polarizer sheet on at least one side thereof, wherein an optical functional layer is disposed between at least one polarizer sheet and the display panel.
Another embodiment of the invention provides a manufacturing method of a display device, comprising: forming an optical functional layer on a surface of a side of a polarizer sheet; and attaching the side of the polarizer sheet that is formed with the optical functional layer to a surface of a display panel.
Still another embodiment of the invention provides a manufacturing method of a display device, comprising: forming an optical functional layer on a surface on at least one side of a display panel; and attaching the at least one side of the display panel that is formed with the optical functional layer to a surface of a polarizer sheet.
In order to clearly illustrate the technical solution of the embodiments of the invention, the drawings of the embodiments will be briefly described in the following; it is obvious that the described drawings are only related to some embodiments of the invention and thus are not limitative of the invention.
In order to make objects, technical details and advantages of the embodiments of the invention apparent, the technical solutions of the embodiments will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the invention. Apparently, the described embodiments are just a part but not all of the embodiments of the invention. All other embodiments obtained by those skilled in the art without any creative labor based on the described embodiments of the present invention belong to the scope of the present invention.
As illustrated in
An optical functional layer 13 is provided between at least one polarizer sheet 1 and the display panel 3.
The display device provided in the embodiment of the present invention includes a display panel provided with a polarizer sheet, and the optical functional layer is disposed between at least one polarizer sheet and the display panel. With the display device of such a structure, the flatness of the contact surface between the polarizer sheet and the cover glass is guaranteed while overcoming various optical badness including glare, which avoids generation of bubbles, and effectively addresses the problem of bubble occurrence in prior art due to the provision of optical functional layer between the cover glass and the display panel.
It is to be noted that the display device may be ally product or component with display function such as a liquid crystal panel, electronic paper, an OLED panel, a mobile phone, a tablet computer, a TV set, a display, a notebook computer, a digital picture frame, and a navigator. Such a structure of optical functional layer provided in the embodiment of the present invention may be applicable to various known display devices including liquid crystal display panels and OLED display devices.
Furthermore, in the manufacturing process, the optical functional layer 13 may be disposed on a surface of the polarizer sheet 1 and then the side of the polarizer sheet 1 provided with the optical functional layer 13 is attached to the display panel, as illustrated in
In an embodiment of the present invention, the optical functional layer 13 includes at least one of an anti-glare layer, a hardened layer and a low reflection layer.
For example, while applied to a liquid crystal display device, the display panel 3 is a liquid crystal display panel. The liquid crystal display panel may be a liquid crystal display panel with any structure in the prior art, which is not limited herein.
Since a liquid crystal display panel generally can only rotate polarized light with a certain polarization angle, in the liquid crystal display device illustrated in
It is to be noted that for the liquid crystal display device, it is possible to dispose optical functional layers between both polarizer sheets located on both sides of the liquid crystal display panel and the liquid crystal panel, and it is also possible to dispose an optical functional layer only between a polarizer sheet on one side and the liquid crystal panel, which is not limited in the present invention. In the liquid crystal display device illustrated in
Upon being applied to an OLED display device, the display panel 3 includes an OLED display panel. Similarly to the liquid crystal display device, the OLED display panel may be an OLED display panel with any structure in the prior art, which is not limited herein.
The structure of the OLED display device may be as illustrated in
Furthermore, a touch unit may further be disposed on a surface on the side of light emitting surface of the display panel 3.
For example, taking a liquid crystal display device as an example, as illustrated in
In order to avoid the badness of impacting image quality by metal induction electrode, it is necessary to provide the optical functional layer 13. Such a display device provided in embodiments of the present invention can guarantee the flatness of contact surface between the polarizer sheet and the cover glass, thereby avoiding occurrence of bubbles, while effectively avoiding badness of impacting image quality by metal induction electrode, which effectively addresses the problem of bubble badness between the cover glass and the display panel in prior art due to the provision of optical functional layer.
Furthermore, as illustrated in
In some examples, the optical functional layer 13 may be integral with the protecting layer 12 in the polarizer sheet 1 that faces the display panel 3.
As illustrated in
For example, when the optical functional layer 13 is an anti-glare layer, it is possible to obtain the anti-glare layer by patterning the surface of a protecting layer 12 of the polarizer sheet 1 that faces the side of the display panel 3 to obtain coarse surface undulations. Since the anti-glare layer mainly functions to reflect ambient light, the influence on liquid crystal screen images by ambient light is reduced and the image quality of the liquid crystal screen is improved. The anti-glare layer has a surface with coarse and uneven topology and utilizes the diffuse reflection principle. When the ambient light is incident onto the liquid crystal screen, it experiences diffuse reflection at the anti-glare layer, thereby effectively reducing ambient light that enters the liquid crystal screen.
In some examples, the polarizer sheet 1 may be attached to the display panel 3 by curable glue 4. As illustrated in
