Referring to FIGS. 1 to 3 , the display panel 100 includes a backlight unit 110 , an optical element 130 and a display portion 150 .

The display unit 150 is divided into an active area Aa displaying an image and a bezel area Ab formed on the outer edge of the end of the active area Aa.

The backlight unit 110 is located below the display unit 150 and emits white light. The backlight unit 110 may include a backlight substrate 111 mounted with multiple light sources (not shown in the drawings), a diverging lens 113 and a backlight rear panel 115 located under the backlight substrate 111 . The diverging lens 113 is located on the light source and diffuses the light irradiated by the light source. The optical element 130 diffuses and refracts the light irradiated by the backlight unit 110 to uniformly irradiate white light to the active area Aa which is an effective display area of the display unit 150 . The display unit 150 selectively transmits light of a predetermined wavelength on a pixel-by-pixel basis to display images (still or moving images). In addition, as described above, when the backlight unit 110 is configured, most of the light irradiated by the backlight unit 110 passes through the optical element 130 and then irradiates the active region Aa of the display unit 150 . Conversely, part of the light is positioned at the outer edge of the display unit 150 and enters the frame region Ab where no effective image is displayed. In this embodiment, the display unit 150 may be composed of a liquid crystal display, and its internal structure itself is well known, so its detailed description is omitted.

In this embodiment, the backlight unit 110 is an example of a direct-emitting backlight unit, but it is not limited thereto, and an edge-emitting backlight unit may also be used.

1 to 3, a display panel support structure 300 according to an embodiment of the present invention is used to fix and support the outer edge and internal components of the display panel 100, and may include a back support part 310, a side support part 350 and a reflection part 400.

The back support part 310 is located on the outer edge of the back surface ( 101 in FIG. 1 ) of the display panel 100 , and fixedly supports the lower part of the backlight unit 110 and the lower part of the optical element 130 . For this, the back support part 310 may include first and second back support parts 311 , 313 and an inclined support part 315 .

The first back support part 311 fixes and supports the lower portion of the backlight unit 110 . Among them, the backlight substrate 111 constituting the backlight unit 110 is located on the backlight rear panel 115 , and as shown in FIG. The first back support part 311 may include first and second support regions 311a, 311b respectively supporting the lower portion of the backlight substrate 111 and the lower portion of the extended backlight rear panel 115 . The second support area 311b forms a step difference relative to the first support area 311a.

Moreover, the display panel supporting structure 100 of the embodiment of the present invention may further include a backplane supporting part 320 . The backplane supporting part 320 fixedly supports the backplane 170 for covering the back surface 101 of the display panel 100 . The back support part 320 is integrally formed with the back support part 310 in a state separated by a predetermined interval.

In addition, the display panel supporting structure 100 according to the embodiment of the present invention may further include reinforcing ribs 330 formed across the space between the back supporting portion 310 and the back plate supporting portion 320 and guides 331 for assembling and fixing protruding from the reinforcing ribs 330 .

Moreover, the display panel supporting structure 100 of the embodiment of the present invention may further include an indirect preventing rib 351 , which can prevent indirect indirection of a flexible flat cable (FFC) that transmits power and electrical signals to the film structure of the driver. In addition, a predetermined space 370 is formed between the reinforcing rib 330 and the shield case 500 described later, and a timing controller (Timing Controller; T-CON) board can be mounted in the space 370 . In addition, the space 370 can be used as a heat circulation space to dissipate heat by air cooling.

In addition, as shown in FIG. 2 , the optical element 130 of the display panel 100 has a structure in which the outer edge part protrudes toward the side support portion 350 of the support structure 300 than the backlight unit 110 . The second back support part 313 is used to fix and support the lower part of the protruding and extended part of the optical element 130 , and forms a step difference at a predetermined height relative to the first back support part 311 . Accordingly, when the components of the display panel 100 are disposed on the first and second back support portions 311 and 313 , the support structure 300 does not need to change the shape of the display panel 100 .

The inclined support portion 315 is formed obliquely at a predetermined inclination between the first rear support portion 311 and the second rear support portion 313 . The inclination angle θ of the inclined support portion 315 ranges from 10° to 80°. Wherein, the inclination angle θ is an angle between a line extending from the upper surface of the first back support portion 311 and the inclined support portion 315 . This allows the light reflected from the reflection part 400 on the inclined support part 315 to be concentrated to the end part of the active area Aa. Therefore, the visible area of the display unit 150 can be expanded to a position adjacent to the frame area Ab.

The side support part 350 protrudes from one side of the back support part 310 at a predetermined height, and supports the side of the optical element 130 and the lower part of the outer edge of the display part 150 .

Therefore, the light incident on the back support part 310 and/or the side support part 350 in the backlight is reflected and irradiated in the direction of the display part 150 . Since the reflector 400 is provided as described above, part of the light that goes away from the active region Aa (for example, toward the frame region) without the reflector 400 is directed toward the active region Aa. The reflective part 400 may include a white reflective substance made of oxide coated on the back support part 310 and/or the side support part 350 . Since the reflective part 400 is made of reflective material, the incident light can be reflected to change its moving path, so that the reflected light can fill up to the end of the active area Aa of the display part 150 . Moreover, when the power of the display panel 100 is turned off, the reflection part 400 has the same color feeling as that of the active area Aa.

The reflection part 400 may include at least one of the first to third reflection parts 410 , 430 , 450 according to the installation position. The first reflection part 410 is located on the inner surface of the side support part 350 , the second reflection part 430 is located on the second back support part 313 , and the third reflection part 450 is located on the inclined support part 315 . Wherein, the first to third reflective parts 410, 430, 450 can be formed by coating and doping the white reflective material formed on the side supporting part 350, the second back supporting part 313 and the inclined supporting part 315 as mentioned above, Can reflect incident light. In addition, in addition to being formed by applying a white reflective material, the reflective part 400 may also be formed by adhering a reflective mirror separately.

Referring to FIG. 3 , in order to prevent the corners of the backlight substrate 111 from lifting from the support structure 100 , a locking groove 311 c is formed on the back support portion 311 . That is, the locking groove 311c is formed at a predetermined depth at a portion where the first rear support part 311a intersects with the inclined support part 315 . Therefore, the corners of the backlight substrate 111 on the first back support portion 311a are located in the locking grooves 311c, preventing the corners of the backlight substrate 111 from being warped.

Moreover, the display panel support structure in the embodiment of the present invention may further include: a shielding cover 500 disposed outside the side support portion 350 to prevent the side support portion 350 from being exposed to the outside of the display panel 100 .

The shield case 500 may include a cover main body 510 and a baffle cover part 550 covering the outside of the side support part 350 . The baffle cover part 550 is bent and formed at the end of the cover body 510 to cover the frame area Ab. Wherein, the width of the baffle covering part 550 is 2.0 mm or less. An inclined support portion 315 is formed on the support structure of the display panel, and a reflective portion 450 is provided on the inclined support portion 315, so that the effective image area, that is, the active area Aa, can be expanded and an extremely narrow frame can be formed.
