Description

TECHNICAL FIELD

Embodiments of the disclosure relate to a display device and an assembling method thereof.

BACKGROUND

With rapid developments of Liquid Crystal Display Televisions (LCD TVs), people have become increasingly demanding for the LCD TVs. Early LCD TVs are very thick with a very wide frame, which look relatively less attractive; in order to solve this problem, manufacturers compete to design a variety of narrow-frame, ultra-narrow frame, or frameless ultra-thin LCD TVs, and particularly, the frameless LCD TVs have a very magnificent appearance.

The frameless structure may be realized by frame bonding technology, that is, bonding a periphery of a liquid crystal panel and a periphery of a glass plate together by a double-sided adhesive tape or other adhesives, assembling the bonded liquid crystal panel and glass plate with a backlight unit, to form the frameless LCD TV with the surface of the glass plate as the appearance surface of the LCD TV. However, in the frame bonding technology, merely the periphery of the liquid crystal panel and the periphery of the glass plate are bonded, so that an air layer is formed between an intermediate portion of the liquid crystal panel and an intermediate portion of the reinforced glass and double image will appear when the user views the screen.

DETAILED DESCRIPTION

In order to make objects, technical details and advantages of the embodiments of the invention apparent, the technical solutions of the embodiment will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the invention. It is obvious that the described embodiments are just a part but not all of the embodiments of the invention. Based on the described embodiments herein, those skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the scope of the invention.

FIG. 1 is a structural schematic diagram illustrating a display device according to embodiments of the disclosure; FIG. 2 is a schematic diagram illustrating the display device according to the embodiments of the disclosure in which a support mechanism is fixed to a frame by a screw.

As shown in FIG. 1 and FIG. 2, the display device according to the embodiments of the disclosure comprises a frame 5 and a display module 11 provided inside the frame 5, the display module 11 comprises a liquid crystal panel 1 and a transparent cover plate 2. A transparent bonding adhesive 3 is fully filled between a light exit surface of the liquid crystal panel 1 and a surface of the transparent cover plate 2 facing the liquid crystal panel 1, and bonds the light exit surface of the liquid crystal panel 1 with the surface of the transparent cover plate 2 facing the liquid crystal panel 1.

A support mechanism 4 is disposed on an inner surface of the frame 5, and the support mechanism 4 is bonded with the liquid crystal panel 1 and/or the transparent cover plate 2 to support the liquid crystal panel 1 and the transparent cover plate 2.

In the above-described display device, the transparent cover plate 2 of the display module 11 is provided inside the frame 5 and the surface of the transparent cover plate 2 is an appearance surface of the display device, so the display device is a frameless display device. In the above-described display device, the light exit surface of the liquid crystal panel 1 of the display module 11 is completely bonded with the surface of the transparent cover plate 2 facing the liquid crystal panel 1, so that there is no air layer between the liquid crystal panel 1 and the transparent cover plate 2, double image will not appear in a display screen of the display device, and image is of a good quality.

For example, the transparent bonding adhesive 3 is made of a jelly glue.

For example, the frame 5 is made of aluminum, and the support mechanism 4 is made of aluminum as well.

Since aluminum has a good thermal conductivity, the frame 5 and the support mechanism 4 made of aluminum enable a rapid heat dispersion of the liquid crystal panel 1, so that the display module 11 has a good heat dispersion property.

For example, the frame 5 and the support mechanism 4 are not integrally formed. Further, for example, the support mechanism 4 is fixed to the frame 5 by a screw.

Since in the above-described display device, the support mechanism 4 is bonded with the liquid crystal panel 1 and/or the transparent cover plate 2 of the display module 11 and the support mechanism 4 and the frame 5 are not integrally formed and fixed with each other by the screw, the frame 5 can be easily separated from the support mechanism 4 by loosing the screw and is replaced when the frame 5 functions poorly. Thus, when the support mechanism 4 and the frame 5 are not integrally formed, a rework cost can be reduced when certain component of the above-described display device functions poorly.

For example, the support mechanism 4 is bonded with the liquid crystal panel 1 and/or the transparent cover plate 2 with a bonding material 6 in modes of:

Mode 1: the support mechanism 4 is bonded with the liquid crystal panel 1 and/or the transparent cover plate 2 by a double-sided adhesive tape 6′:

Mode 2: the support mechanism 4 is bonded with the liquid crystal panel 1 and/or the transparent cover plate 2 by a silicone adhesive 6′.

Of course, the support mechanism 4 may be bonded with the liquid crystal panel 1 and/or the transparent cover plate 2 by other bonding material substances 6 such as glue.

For example, the transparent cover plate 2 is a reinforced glass cover plate or a transparent plastic cover plate.

As shown in FIG. 1, the display module 11 further comprises a backlight unit. The backlight unit comprises a rear housing 10; and a light source 7, a reflective sheet 8′, a light guide plate 8 and optical films 9 provided between the rear housing 10 and the liquid crystal panel 1.

For example, the rear housing 10 is made of aluminum, and the light source 7 is a bar of LEDs.

As shown in FIG. 1, the light source 7 is attached to the support mechanism 4, and the light guide plate 8 and the rear housing 10 are fixed to the support mechanism 4.

Since the light source 7 is attached to the support mechanism 4 and the support mechanism 4 is connected to the frame 5 and the rear housing 10, the support mechanism 4, the frame 5 and the rear housing 10 made of aluminum enable a rapid heat dispersion of the light source 7, so that the backlight unit has a good heat dispersion property.

For example, the rear housing 10 constitutes a shell of the display device.

The rear housing 10 of the backlight unit is used as the shell of the display device, so that a backplate of the display device in the prior art can be omitted and a better heat dispersion property can be achieved.

As shown in FIG. 1, the display device further comprises a function module 12, and the function module 12 is provided on an outside surface of the rear housing 10 of the backlight unit.

Since the function module 12 is provided on the outside surface of the rear housing 10, the display module 11 and the function module 12 can be separated so that the display module 11 can be made thinner. In addition, each of the display module 11 and the function module 12 has various configurations and the various configurations of the display module 11 and the various configurations of the function module 12 can be combined arbitrarily, so that the display device can be customized to meet the needs of the users.

The embodiments of the disclosure further provide an assembling method of a display device. For example, the assembling method comprises steps of:

Step S101: fully filling the transparent bonding adhesive 3 between the liquid crystal panel 1 and the transparent cover plate 2 so that the liquid crystal panel 1 and the transparent cover plate 2 are completely bonded with each other;

Step S102: bonding the liquid crystal panel 1 and the transparent cover plate 2 that have been bonded with each other to the support mechanism 4 disposed on the inner surface of the frame 5.

Step S103: attaching the light source 7 of the backlight unit to the support mechanism 4, sequentially stacking the optical films 9, the light guide plate 8 and the reflective sheet of the backlight unit along a direction from the light exit surface to a light entrance surface of the liquid crystal panel 1, and fixing the rear housing 10 of the backlight unit to the support mechanism 4.

In the display device obtained by the above-described assembling method, the liquid crystal panel 1 and the transparent cover plate 2 bonded with each other are provided inside the frame 5 and the surface of the transparent cover plate 2 is an appearance surface of the display device, so the display device is a frameless display device. In the above-described step S101, the light exit surface of the liquid crystal panel 1 of the display module 11 is completely bonded with the surface of the transparent cover plate 2 facing the liquid crystal panel 1, so that there is no air layer between the liquid crystal panel 1 and the transparent cover plate 2, double image will not appear in the display screen of the display device, and image is of a good quality.

The foregoing embodiments merely are exemplary embodiments of the disclosure, and not intended to define the scope of the invention, and the scope of the invention is determined by the appended claims.
