The subject matter herein generally relates to display devices, and more particularly to a display device having a borderless display module.
A liquid crystal display (LCD) is generally used in flat, thin display devices. Currently, a bezel of the LCD limits a full-screen potential of the LCD.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
The display panel 21, the optical film set 22, and the backplane 23 are stacked in sequence. One first bonding member 24 is disposed between the display panel 21 and the optical film set 22, and a second first bonding member 24 is disposed between the optical film set 22 and the backplane 23 to bond the display panel 21, the optical film set 22, and the backplane 23 together. The second bonding member 25 is disposed on a peripheral side of the display panel 21, the optical film set 22, and the backplane 23. The second bonding member 25 enhances a bonded connection of the display panel 21, the optical film set 22, and the backplane 23 and is configured to prevent light leakage. The second bonding member 25 is an outer side surface of the display module 20 and protects the side of the display module 20.
The display panel 21 is substantially rectangular plate-shaped. The optical film set 22 is substantially the same size as the display panel 21 and includes a first adhering surface 221 facing the display panel 21 and a second adhering surface 222 facing the backplane 23. A size of the backplane 23 is substantially the same as a size of the display panel 21. The two first bonding members 24 are respectively uniformly applied on the first adhering surface 221 and the second adhering surface 222. The second bonding member 25 is applied to the peripheral sides of the display panel 21, the optical film set 22, and the backplane 23. In one embodiment, the display panel 21 is a liquid crystal display panel, and a surface of the display panel 21 is provided with a cover glass. The optical film set 22 may be a plurality, such that the plurality of optical film sets 22 are stacked, and every two adjacent optical film sets 22 are bonded together by a first bonding member 24.
The first bonding members 24 may be a translucent optical adhesive or a double-sided adhesive tape. Specifically, the first bonding members 24 may be foam tape, ultraviolet glue, or hot melt adhesive. In addition, the first bonding members 24 may be other kinds of optical adhesives having light transmitting properties according to actual needs.
The second bonding member 25 is made of a non-transparent material. In one embodiment, the second bonding member 25 is silica gel. In other embodiments, the second bonding member 25 can be made of other kinds of light non-transmitting materials that do not have translucency.
In assembly, the backplane 23 is placed on a positioning carrier, and a dispensing device uniformly applies one first bonding member 24 on the backplane 23. Then, the optical film set 22 is stacked on the backplane 23, the other first bonding member 24 is uniformly applied on the first adhering surface 221, and the display panel 21 is stacked on the first adhering surface 221, so that the backplane 23, the optical film set 22, and the display panel 21 are bonded together. Then, a dispensing device applies the second bonding member 25 to the peripheral side of the display panel 21, the optical film set 22, and the backplane 23.
It should be understood that the dispensing device is selected according to characteristics (viscosity, curing mode) of the bonding members and process parameters (dispensing accuracy, shape, and size) and the like. The dispensing device may be a mechanical arm, a three-axis platform, or a hand-held device.
The display module 20 bonds the display panel 21, the optical film set 22, and the backplane 23 together through the first bonding members 24 having light transmissibility and the second bonding member 25 made of non-transparent material. The second bonding member 25 improves a bonding connection of the display panel 21, the optical film set 22, and the backplane 23. The second bonding member 25 is an outer side surface of the display module 20 and prevents light leakage and protects the side of the display module 20. The display module 20 requires no bezel, which not only saves manufacturing costs, but also reduces thickness of the display module 20.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
