An exemplary embodiment of the present invention also provides a display device including the above-described bracket.

According to an aspect of the exemplary embodiment, there is provided a bracket for a display panel, the bracket including a first flat panel for contacting the display panel; a second panel facing the first flat panel and having a smaller area than the first flat panel a plate; and a spacer between the first plate and the second plate.

The first panel may have an edge portion that extends beyond the edge of the second panel.

The bracket may further include a flat plate located on an edge portion of the first flat plate and coupled to the display panel.

The thickness of the outer plate may be less than or equal to the distance from the edge of the first plate to the outer surface of the second plate.

The outer panel, the first panel, the second panel, and the spacer can comprise substantially similar materials.

The outer plate, the first plate, the second plate, and the spacer may comprise aluminum.

The spacer may comprise a honeycomb structure.

The spacer may comprise a wavy structure.

The second plate may have a curved portion extending from the edge of the second flat plate toward the first flat plate and configured to contact the first flat plate.

The display panel may include an organic light emitting display (OLED) panel.

According to an aspect of the exemplary embodiments, a bracket for a display panel including a display area and a non-display area is provided, the bracket may include a first flat panel contacting the display panel; facing the first flat panel and having a smaller than The area of a flat plate to expose the second flat plate of the edge portion of the first flat plate, the edge portion corresponding to the non-display area of the display panel; and the spacer between the first flat plate and the second flat plate.

The area of the second plate may be substantially equal to the area of the display area of the display panel.

The bracket may further include a flat plate on an edge portion of the first flat plate to be coupled to the display panel.

The thickness of the outer plate may be less than or equal to the distance from the edge of the first plate to the outer surface of the second plate.

The outer panel can contact the first panel in an area corresponding to the non-display area of the display panel.

The spacer may comprise a honeycomb structure.

The spacer may have a wavy structure.

The second plate may include a bend extending from the edge of the second plate toward the first plate and configured to contact the first plate.

The bracket may include a first plate for contacting the display panel; a second plate facing the first plate and having an area smaller than the first plate; and a spacer interposed between the first plate and the second plate.

The display panel may include an organic light emitting display (OLED) panel.

According to an exemplary embodiment, the second flat plate may have an area smaller than the first flat plate such that an edge portion of the first flat plate corresponding to the non-display area of the display panel may be exposed by the second flat plate. In particular, the thickness of the outer panel may be less than or equal to the distance from the exposed edge portion of the first panel to the outer surface of the second panel. Therefore, the thickness of the outer plate does not increase the total thickness of the bracket, so the bracket can have a relatively thin thickness and a light weight. Further, since the outer panel can be located at the edge portion of the first flat panel corresponding to the non-display area of the display panel, the outer panel can not degrade the display quality of the display panel.

Since the consumer may desire a lighter display panel, the weight of the bracket may be reduced. However, a relatively light bracket may require a structure that stably supports a relatively heavy display panel. Furthermore, it is advantageous to provide a bracket having a structure that can degrade the display quality of an image of a display area of the display panel.

Recently, since the thickness of the display panel can be reduced, it can be advantageous to develop a thin carrier having the above requirements.

A cross-sectional view taken at line III-III', and Fig. 4 is an enlarged plan view showing the structure within the portion IV of Fig. 2.

Referring to FIGS. 1 through 4, the cradle 100 for the display panel D (see FIG. 6) according to the present exemplary embodiment may include a first flat plate 110, a second flat plate 120, and a spacer 130. In this embodiment, the display panel D may have a display area and a non-display area. The display area may correspond to a central portion of the display panel D, and the non-display area may correspond to an edge portion of the display panel D. The display panel D may include an organic light emitting display (OLED) panel, a liquid crystal display (LCD) panel, a plasma display panel, and the like.

In the embodiment, the first flat plate 110 may have a rectangular shape and may be in contact with the display panel D to support the display panel D.

The second plate 120 can be located above the first plate 110 and can thus face the first plate 110. In the embodiment, the second flat plate 120 may have a rectangular shape.

The spacer 130 may be between the first flat plate 110 and the second flat plate 120, and may each have a lower end coupled to the upper surface of the first flat plate 110 and a lower end coupled to the lower surface of the second flat plate 120. As shown in FIG. 4, the spacer 130 can partition a space between the first flat plate 110 and the second flat plate 120 into a honeycomb structure.

The honeycomb-shaped spacer 130 may be relatively strong and may inhibit heat transfer, such as heat generated from the display panel D, from being transmitted in a first direction from the first flat plate 110 to the second flat plate 120. In contrast, the honeycomb-shaped spacer 130 may disperse heat transmitted in a second direction perpendicular to the first direction. Therefore, the heat generated from the display panel D can be quickly dissipated to the outside through the honeycomb-shaped spacer 130.

In this embodiment, the first flat plate 110, the second flat plate 120, and the spacer 130 may comprise substantially the same material, such as a metal of aluminum. Because the first plate 110, the second plate 120, and the spacer 130 can have the same material, the carrier 100 can have a substantially continuous structure. Therefore, discontinuous lines in the temperature distribution of the display panel D can be avoided.

In this embodiment, the second flat plate 120 may have an area smaller than the first flat plate 110. Therefore, the first flat plate 110 may have the edge portion 112 that is not covered by the second flat plate 120. That is, the edge portion 112 of the first flat plate 110 may extend beyond the circumference of the second flat plate 120 and may thus be exposed by the second flat plate 120. Therefore, a space can be formed above the edge portion of the first flat plate 110. The outer plate 140 (see Fig. 6) may be located in a space above the edge of the first plate 110. The edge portion 112 of the first flat plate 110 may correspond to a non-display area of the display panel D. Therefore, the second flat panel 120 can have substantially the same area as the display area of the display panel D.

Alternatively, the edge portion of the preliminary second plate (eg, the precursor of the second plate 120) having substantially the same area as the first plate 110 may be removed by a press process to form The second flat plate 120 is smaller than the area of the first flat plate 110. Since the honeycomb carrier 100 can have a very low volume ratio (e.g., density), the edge portion of the preliminary second flat plate can be easily pressed.

Fig. 5 is a perspective view showing a plate outside the bracket of the embodiment shown in Fig. 1, and Fig. 6 is a sectional view taken along line VI-VI' of Fig. 5, and Fig. 7 is a sectional view Fig. 8 is an enlarged cross-sectional view of a portion VII of Fig. 6, and Fig. 8 is a plan view showing the decorative frame of the bracket having the embodiment shown in Fig. 5.

Referring to Figures 5 through 7, the bracket 100a of this embodiment may further include an outer plate 140. The outer panel 140 can be coupled to the cradle 100a and can include four slabs arranged on four sides of the cradle 100a.

In an exemplary embodiment, the outer panel 140 may be adhered to the bracket 100a using a double-sided adhesive tape, an adhesive, or the like. Alternatively, the outer plate 140 can be fixed to a clamp (not shown). The pressed edge portion of the bracket 100a can be assembled with the outer plate 140. Since the outer plate 140 can be positioned, the process for applying pressure and cutting the edge portion of the second plate 120 can have a sufficiently wide gap.

In this embodiment, the outer plate 140 may be located on the exposed surface of the first plate 110, that is, the edge portion of the first plate 110, which may correspond to the non-display area of the display panel D. Therefore, the outer panel 140 can also be located or correspond to the non-display area of the display panel D. Therefore, the display quality of the display panel D may not be deteriorated by the outer panel 140. In particular, the main cause of deterioration of the display quality of the display panel D may be the boundary line I between the outer panel 140 and the first panel 110. The boundary line I (see Figure 7) can be located in the non-display area of the display panel D. Therefore, the boundary line I between the outer flat plate 140 and the first flat plate 110 can not impair the display quality of the display panel D.

In this embodiment, the outer plate 140 may comprise substantially the same material as the first plate 110, the second plate 120, and the spacer 130, such as a metal such as aluminum. Therefore, since the outer panel 140 can comprise substantially the same material as the bracket 110a, the outer panel 140 can have no effect on the display quality of the display panel D.

In the present embodiment, the outer plate 140 may have a thickness T that is substantially the same or smaller than the distance H from the inner surface of the first plate 110 to the outer surface of the second plate 120 (see FIG. 7). Here, the inner surface of the first flat plate 110 may face the second flat plate 120, and the other surface of the second flat plate 120 may be oriented opposite to or away from the first flat plate 110. That is, the thickness T of the outer flat plate 140 may be smaller than the distance H between the inner surface of the first flat plate 110 and the outer surface of the second flat plate 120. Therefore, the outer flat plate 140 on the edge portion of the first flat plate 110 may not protrude from the outer surface of the second flat plate 120. Therefore, the thickness T of the outer plate 140 may not increase the total thickness of the bracket 100a. That is, the total thickness of the bracket 100a may correspond to a distance between the outer surface of the first flat plate 110 and the outer surface of the second flat plate 120. Since the total thickness of the bracket 100a may not include the thickness T of the outer flat plate 140, the honeycomb bracket 100a having a relatively thin thickness can stably support the relatively heavy display panel D.

A printed circuit board (PCB) P can be arranged on the outer panel 140 and can supply electronic signals to the display panel D.

Referring to Figure 8, the decorative frame 150 can be disposed on the outer panel 140. The decorative frame 150 can be located in the non-display area of the display panel D. Therefore, the decorative frame 150 can not damage the display quality of the display panel D.

Figure 9 is a cross-sectional view of a bracket for a display panel in accordance with an exemplary embodiment.

Although the shape of the spacers may vary, the bracket 100b of the present embodiment may include substantially the same components as the bracket 100a of the embodiment shown in FIG. Therefore, the same reference numerals may be used to refer to the same elements, and any further discussion with respect to the same elements for the sake of brevity may be omitted herein.

Referring to Fig. 9, the spacer 130a of the bracket 100b may have a wavy shape. The corrugated spacer 130a may have a lower end fixed to the first flat plate 110 and a lower end fixed to the second flat plate 120. The bracket 100b having the undulating spacer 130a may be similar in shape to the corrugated cardboard.

In an exemplary embodiment, the outer plate 140 can be coupled to the first plate 110 through the thermal conductive tape 160.

The carrier 100b having the undulating spacers 130a can be fabricated by a relatively simple process of manufacturing the carrier 100 with the honeycomb spacers 130.

Figure 10 is a cross-sectional view showing a bracket for a display panel in accordance with an exemplary embodiment.

Although the second flat plate is different, the bracket 100c of the present embodiment may include substantially the same elements as the bracket 100a of the embodiment shown in FIG. Therefore, the same reference numerals may be used to refer to the same elements, and any further discussion of the same elements for the sake of brevity may be omitted herein.

Referring to FIG. 10, the second plate 120 of this embodiment may have a curved portion 122. The curved portion 122 may be vertically bent from the edge of the second flat plate 120 toward the first flat plate 110. The curved portion 122 may contact the upper surface of the first flat plate.

The cradle 100, 100a, 100b, and 100c of the embodiment may be included in a display device. Therefore, the display device may include any one of the cradle 100, 100a, 100b, and 100c and the display panel D.

Display panel temperature distribution measurement

The temperature distribution of the display panel supported by the bracket of the embodiment shown in Fig. 5 is shown in Fig. 11. As shown in Fig. 11, the heat can be uniformly distributed in the display area of the display panel. Therefore, the honeycomb carrier can substantially uniformly disperse the heat generated from the display panel.

Display panel temperature measurement

The temperature of the first display panel supported by the carrier without the storage space of the outer panel is measured. The temperature of the second display panel supported by the carrier of the embodiment shown in Fig. 6 and having the storage space of the outer panel is measured. As shown in Fig. 12, the measured temperatures of the respective seven points on the first display panel and the second display panel are shown in the following table.

form

As shown in the table, the first display panel supported by the carrier without the storage space of the outer panel may have a relatively large temperature difference of 10.5 ° C (for example, the difference between the maximum temperature and the minimum temperature). However, the second display panel of the exemplary embodiment supported by the cradle and having an outer flat storage space may have a relatively small temperature difference of 1.6 °C. Therefore, the second display panel supported by the honeycomb tray can have a relatively more uniform temperature distribution.

According to an exemplary embodiment, the second flat plate may have an area smaller than the first flat plate such that an edge portion of the first flat plate corresponding to the non-display area of the display panel may be exposed by the second flat plate. More particularly, the thickness of the outer panel can be less than or equal to the distance from the exposed surface of the first panel to the outer surface of the second panel. Therefore, the thickness of the outer plate may not increase the overall thickness of the carrier so that the carrier can have a relatively thin thickness and a relatively light weight. Further, since the outer panel may be located at an edge portion of the first panel corresponding to the non-display area of the display panel, the outer panel may not reduce the display quality of the display panel.

The exemplary embodiments are discussed above and are not to be construed as limiting. While the invention has been described with respect to the embodiments of the embodiments of the invention, various modifications of the exemplary embodiments are possible. Therefore, all such modifications are intended to be included within the scope of the illustrative embodiments defined by the scope of the claims. In the context of the patent application, the means-function additional language is intended to encompass the structures described herein for performing the described functions, and not only structural equivalents but also equivalent structures. Therefore, the above description is intended to be illustrative of the exemplary embodiments, and the invention It is included in the scope of the appended claims.
