As shown in
Further, as shown in
The light source 11 includes a plurality of light emitting diodes 11a to generate light and a substrate 11b on which the plurality of light emitting diodes 11a is arranged in a line.
The light guide member 12 is formed in a plate shape. Light irradiated by the light source 11 is incident upon the light guide member 12 through the side surface thereof, and is then guided forwards. A reflective sheet 12a is disposed on the rear surface of the light guide member 12 so as to reflect the light forwards.
In this exemplary embodiment, the front surface of the glass member 14 and the front surface of the frame 15 are substantially coplanar. In order to maintain such a state in which the front surface of the glass member 14 and the front surface of the frame 15 are coplanar, a support rib 15a protruded integrally from the inner surface of the frame 15 to support the edge of the rear surface of the glass member 14 is formed on the frame 15.
In this exemplary embodiment, the support rib 15a is formed at a position having the same depth as the thickness of the glass member 14, and the optical sheet 13 and the light guide member 12 are sequentially installed on the rear surface of the support member 16. Here, light having passed through the edge of the light member 12 supported by the support rib 15a is blocked by the support rib 15a, and thus is not transmitted to the front of the support rib 15a. Therefore, a front support part 16a of the support member 16 may have a width corresponding to that of the support rib 15a.
The support member 16 includes the front support part 16a to support the edge of the front surface of the glass member 14 and the front surface of the frame 15, and a side support part 16b extended backwards from the front support part 16a to support the side surfaces of the frame 15. Thereby, the support member 16 prevents the glass member 14 from being separated from the frame 15.
A film member 17B is disposed on the remaining portion of the front surface of the glass member 14 excluding the edge of the front surface of the glass member 14 supported by the front support part 16a. If the display apparatus 10 has the above structure, a region of the display apparatus 10 provided with the film member 17B disposed thereon constitutes the display part 10a, and a region of the display apparatus 10 provided with the front support part 16a provided thereon constitutes the bezel part 10b. The film member 17B has the same thickness as that of the front support part 16a. If the front support part 16a and the film member 17B have the same thickness and the front support part 16a and the film member 17B are disposed on the front surfaces of the frame 15 and the glass member 14, which are substantially coplanar, the front surface of the front support part 16a and the front surface of the film member 17B become coplanar and thus the front surface of the display part 10a and the front surface of the bezel part 10b become coplanar.
In this exemplary embodiment, two film members 17A and 17B, each of which is made of a polarizing film, are provided. The film member 17A is disposed between the light guide member 12 and the optical sheet 13 and the film member 17B is disposed on the front surface of the glass member 14, as described above.
In order to maintain a state in which the light guide member 12 is installed on the frame 15, the rear cover 18 to support the rear surface of the light guide member 12 is disposed on the rear surface of the light guide member 12. Here, the side end of the rear cover 18 is fixed to the frame 15.
The side surface of the light guide member 12 is separated from the frame 15 so that light irradiated by the light source 11 is incident upon the light guide member 12 through the side surface thereof, and the light emitting diodes 11a are disposed at the rear portion of a space between the side surface of the frame 15 and the side surface of the light guide member 12. Further, a reflective plane 15b, which is formed to have a curved surface so as to reflect the light irradiated by the light emitting diodes 11a toward the side surface of the light guide member 12, is provided on the inner surface of the frame 15 facing the side surface of the light guide member 12. In this exemplary embodiment, the frame 15 is made of a metal, such as aluminum, so as to reflect light.
In order to install the light emitting diodes 11a at the rear portion of the space between the side surface of the frame 15 and the side surface of the light guide member 12, a light source installation part 18a integrally extended backwards from the side end of the rear cover 18 is provided at the side end of the rear cover 18 such that the light source 11 is installed in the light source installation part 18a. The light source 11 is installed in the light source installation part 18a such that the rear surface of the substrate 11b is supported by the light source installation part 18a, and a spacer 19, the front surface of which is supported by the rear surface of the light guide member 12 and the rear surface of which is supported by the front surface of the substrate 11b, is disposed between the rear surface of the light guide member 12 and the substrate 11b.
Since light generated by the light emitting diodes 11a is irradiated in an approximate fan shape, overlapping and mixing of the light generated by the plural light emitting diodes 11a occur. Therefore, in order to obtain uniform brightness, a designated mixing distance or more is required. In order to secure such a mixing distance, the bezel part 10b requires a width of more than a designated value, thus limiting reduction of the width of the bezel part 10b.
Therefore, if the light emitting diodes 11a are disposed at the rear portion of the space between the inner surface of the frame 15 and the side surface of the light guide member 12 and the reflective plane 15b is provided on the inner surface of the frame 15 facing the side surface of the light guide member 12, light irradiated by the light emitting diodes 11a moves by a designated distance in the forward and backward directions, is reflected by the reflective plane 15b, moves back to the side surface of the light guide member 12, and is then incident upon the light guide member 12 through the side surface of the light guide member 12. Therefore, the movement distance of the light irradiated by the light emitting diodes 11a to the side surface of the light guide member 12 may be greatly reduced and the mixing distance may be sufficiently secured. Thus, the width of the bezel part 10b may be reduced by the amount by which the movement distance of the light to the side surface of the light guide member 12 is reduced.
Although this exemplary embodiment describes the optical sheet 13 as being disposed on the front surface of the light guide member 12, the position of the optical sheet 13 is not limited thereto. That is, as shown in
Hereinafter, with reference to
As shown in
In this exemplary embodiment, an installation recess 34a in which a front support part 36a of the support member 36 is installed is provided at the edge of the front surface of the glass member 34. Here, the thickness of the installation recess 34a is equal to the thickness of the front support part 36a. If the thickness of the installation recess 34a is equal to the thickness of the front support part 36a, the front surface of the front support part 36a and the front surface of the glass member 34 excluding the portion of the glass member 34 provided with the installation recess 34a become coplanar.
A film member 37B is disposed on the front surface of the front support part 36a and the remaining portion of the front surface of the glass member 34 excluding the portion of the glass member 34 provided with the installation recess 34a. Thereby, a region of the display apparatus 30 provided with the remaining portion of the glass member 34 excluding the portion thereof provided with the installation recess 34a constitutes a display part 30a, and a region of the display apparatus 30 provided with the front support part 36a constitutes a bezel part 30b. Light having passed through the edge of the light guide member 32 supported by a support rib 35a is blocked by the support rib 35a, and thus is not transmitted to the front of the support rib 35a. Therefore, the front support part 36a of the support member 36 may have a width corresponding to that of the support rib 35a.
Hereinafter, with reference to
As shown in
The front surface of the glass member 44 is coplanar with the front surface of the frame 45, and the film member 47B is disposed on the front surface of the glass member 44 and the front surface of the frame 45. In this exemplary embodiment, the side end of the film member 47B is extended backwards so that the film member 47B covers the side surface of the frame 45 as well as the front surface of the glass member 44 and the front surface of the frame 45. Since the film member 47B covers the front surface of the glass member 44 and the front and side surfaces of the frame 45, the film member 47B serves to maintain a state in which the glass member 44 is installed on the frame 45.
A support rib 45a protruded from the inner surface of the frame 45 to support the edge of the rear surface of the glass member 44 is formed on the frame 45, and light having passed through the light guide member 42 does not pass through the support rib 45a. Therefore, a region of the display apparatus 40 provided with the front surface of the frame 45 and the edge of the glass member 44 supported by the support rib 45a constitutes a bezel part 40b, and a region of the display apparatus 40 provided with the remaining portion of the glass member 44 excluding the edge of the glass member 44 constitutes a display part 40a.
If the front surface of each of the display parts 10a, 20a, 30a and 40a and the front surface of each of the bezel parts 10b, 20b, 30b and 40b are coplanar, as described in the above exemplary embodiments, each of the display parts 10a, 20a, 30a and 40a and each of the bezel parts 10b, 20b, 30b and 40b are not indistinguishable in appearance, and thus display apparatuses 10, 20, 30 and 40 having a simpler design may be implemented.
Although the above exemplary embodiments describe that the light sources 11, 21, 31 and 41 are separated from the rear surfaces of the light guide members 12, 22, 32 and 42 by the spacers 19, 29, 39 and 49, disposition of the light sources 11, 21, 31 and 41 is not limited thereto. That is, as shown in
Although the above exemplary embodiments describe the frames 15, 25, 35, 45 and 55 as being made of a metal, such as aluminum, so as to reflect light irradiated by the light emitting diodes 11a, 21a, 31a, 41a and 51a, the frames 15, 25, 35, 45 and 55 are not limited thereto. That is, the frames 15, 25, 35, 45 and 55 may be made of a material, which does not efficiently reflect light, and a white or silver film member may be attached to the reflective planes 15b, 25b, 35b, 45b and 55b or white or silver paint may be applied to the reflective planes 15b, 25b, 35b, 45b and 55b so as to achieve efficient light reflection.
As is apparent from the above description, a display apparatus in accordance with one exemplary embodiment of the present invention allows the front surface of a display part and the front surface of a bezel part to be substantially coplanar with each other such that the display part and the bezel part are indistinguishable in appearance, thereby achieving a simpler design of the display apparatus.
Further, in the display apparatus in accordance with the exemplary embodiment of the present invention, a light source is disposed at the rear portion of a space between a frame and a light guide member and a reflective plane to reflect light, irradiated by light emitting diodes located at the rear of the frame, to the side surface of the light guide member is provided on the frame, thereby causing the light irradiated by the light emitting diodes to move forwards by a designated distance and then to be reflected and be incident upon the side surface of the light guide member, thus being capable of reducing the width of the bezel part while securing a sufficient mixing distance.
Although a few exemplary embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
