5, the optical layer 123 may include a substrate 122, a reflective sheet 123, an optical assembly 124, and a light guide plate 128.

The optical layer 123 may be located on the frame 130. For example, the optical layer 123 may be positioned between the frame 130 and the optical sheet 125. [ The optical layer 123 can be supported by the frame 130.

The substrate 122 may be located on at least one side of the frame 130. The substrate 122 may be coupled to the first guide panel 117. The substrate 122 may be directly coupled to the first guide panel 117. For example, the substrate 122 may be configured to be coupled to at least one of the first guide panel 117, the frame 130, and the top case 105.

The substrate 124 may be positioned in the lateral direction of the reflective sheet 123 and / or the light guide plate 128. That is, it means that the front surface of the substrate 124 can be directed to the optical layer 123. The substrate 124 and the reflective sheet 123 and / or the light guide plate 128 may be spaced apart from each other by a predetermined distance. The specific configuration of the substrate 122 and the optical layer 123 will be described in corresponding portions.

The substrate 122 may be located on at least one side of the other configuration of the optical layer 123. The substrate 122 may extend in a direction orthogonal to the longitudinal direction of another configuration of the optical layer 123.

On the substrate 122, at least one optical assembly 124 may be mounted. On the substrate 122, an electrode pattern for connecting the adapter and the optical assembly 124 may be formed. For example, a carbon nanotube electrode pattern may be formed on the substrate 122 to connect the optical assembly 124 and the adapter.

The substrate 122 may be composed of at least one of polyethylene terephthalate (PET), glass, polycarbonate (PC), and silicon. The substrate 122 may be a printed circuit board (PCB) on which at least one optical assembly 124 is mounted.

On the substrate 122, the optical assembly 124 may be disposed with a predetermined gap therebetween. The longitudinal width of the optical assembly 124 may be smaller than the thickness direction width of the light guide plate 128. Therefore, most of the light emitted from the optical assembly 124 can be transmitted to the inside of the light guide plate 128.

The optical assembly 124 may be a light emitting diode (LED) chip or a light emitting diode package including at least one light emitting diode chip.

The optical assembly 124 may be comprised of a colored LED or white LED emitting at least one color from among colors such as red, blue, green, and the like. The colored LED may include at least one of a red LED, a blue LED, and a green LED.

The light source included in the optical assembly 124 may be a COB (Chip On Board) type. The COB type may be a form in which the LED chip, which is a light source, is directly coupled to the substrate 122. Thus, the process can be simplified. In addition, the resistance can be lowered, thereby reducing energy lost by heat. That is, it means that the power efficiency of the optical assembly 124 can be increased. The COB type can provide a brighter light. The COB type can be realized thinner and lighter than the conventional one.

The light guide plate 128 may be located on the upper side of the optical assembly 124. The light guide plate 128 may serve to spread light incident from the optical assembly 124 widely. Although not shown, the light guide plate 128 may have a stepped shape adjacent to the optical assembly 124. The lower surface of the light guide plate 128 is inclined upward so that light incident from the optical assembly 124 can be reflected upward.

The reflective sheet 126 may be positioned on the back side of the light guide plate 128. The reflective sheet 126 may reflect light emitted from the optical assembly 124 to the front side. The reflective sheet 126 can reflect the light reflected from the light guide plate 128 back to the front side.

The reflective sheet 126 may include at least one of a metal and a metal oxide which are reflective materials. For example, the reflective sheet 126, an aluminum (Al), silver (Ag), a metal and / or metal oxide having high reflectance, such as at least any one of gold (Au), and titanium dioxide (TiO ₂₎ .

The reflective sheet 126 may be formed by depositing and / or coating a metal or a metal oxide. The reflective sheet 126 may be printed with an ink containing a metal material. The reflection sheet 126 may have a vapor deposition layer formed by a vacuum vapor deposition method such as a thermal vapor deposition method, an evaporation method, or a sputtering method. A coating layer and / or a printing layer using a printing method, a gravure coating method, or a silk screen method may be formed on the reflective sheet 126.

A diffusion plate (not shown) may further be provided on the front surface of the light guide plate 128. The diffuser plate can diffuse the light emitted from the light guide plate 128 upward.

Between the light guide plate 128 and the optical sheet 125, an air gap may be located. The air gap can serve as a buffer through which light emitted from the optical assembly 124 can spread widely. On the other hand, the resin can be deposited on the optical assembly 124 and / or the reflective sheet 126. The resin may serve to diffuse the light emitted from the optical assembly 124.

The optical sheet 125 may be positioned on the front side of the light guide plate 128. [ The rear surface of the optical sheet 125 is in close contact with the light guide plate 128 and the front surface of the optical sheet 125 is in close contact with the rear surface of the display panel 110.

The optical sheet 125 may include at least one sheet. In detail, the optical sheet 125 may include one or more prism sheets and / or one or more diffusion sheets. The plurality of sheets included in the optical sheet 125 may be in an adhered and / or adhered state.

The optical sheet 125 may be composed of a plurality of sheets having different functions. For example, the optical sheet 125 may include first to third optical sheets 125a to 125c. The first optical sheet 125a has the function of a diffusing sheet and the second and third optical sheets 125b and 125c can function as a prism sheet. The number and / or position of the diffusion sheet and prism sheet may be varied. For example, a first optical sheet 125a, which is a diffusion sheet, and a second optical sheet 125b, which is a prism sheet.

The diffusion sheet can prevent the light coming from the light guide plate 128 from being partially concentrated, thereby making the brightness of the light more uniform. The prism sheet can condense the light coming from the diffusion sheet and allow light to enter the display panel 110 vertically.

The engaging portion 125d may be formed on at least one of the corners of the optical sheet 125. [ The engaging portion 125d may be formed on at least one of the first to third optical sheets 125a to 125c.

The engaging portion 125d may be formed at the long side edge of the optical sheet 125. [ The engaging portion 125d formed on the side of the first long side and the engaging portion 125d formed on the side of the second long side may be asymmetric. For example, the position and / or number of the engaging portion 125d of the first long side and the engaging portion 125d of the second long side may be different from each other.

Referring to FIGS. 8 and 9, the substrate 122 and the optical assembly 124 may be positioned in the direction of the lower side 110c of the display panel 110. FIG. An edge type backlight unit in which the optical assembly 124 is disposed on the side of the display panel 110 can be referred to as an edge type backlight unit.

As shown in Fig. 8, the optical assembly 124 can emit light in the direction from the lower side 110c to the upper side 110d of the display panel 110. [ That is to say that the light emitted from the optical assembly 124 diffuses from the lower side 110c to the upper side 110d of the display panel 110 to emit the entire display panel 110. [ However, the present invention is not limited thereto, and the optical assembly 124 may be positioned on the upper side 110d of the display panel 110. [

As shown in FIG. 9A, the optical assembly 124 may be located on the right side 110a of the display panel 110. However, the present invention is not limited thereto, and the optical assembly 124 may be located on the left side 110b of the display panel 110. [

The optical assembly 124 may be positioned on the lower side 110c and the upper side 110d of the display panel 110, as shown in FIG. 9 (b). 9 (c), the optical assembly 124 may be positioned on the right side 110a and the left side 110b of the display panel 110. In addition, as shown in FIG.

As shown in FIGS. 9 (b) and 9 (c), the optical assembly 124 is disposed on opposite sides of the display panel 110 as a dual type backlight unit. The dual type backlight unit can easily diffuse light to the front surface of the display panel 110 even in weaker light.

The optical assembly 124 may be positioned on the entire surface of the display panel 110, as shown in FIG. 9 (d). If the optical assembly 124 is positioned on the front surface of the display panel 110, light can be more easily diffused than other backlight units.

Fig. 10 is a view showing an optical seating part coupled to a frame, and Fig. 11 is a view showing a substrate coupled to the optical seating part of Fig. 10;

As shown in these drawings, the display device 100 according to an embodiment of the present invention may include an optical seat 200 formed on one side of the frame 130.

10, the optical seating portion 200 may be a portion where the substrate 122 and the optical assembly 124 are accommodated. The optical seating portion 200 may be a portion where the optical layer 123 including the substrate 122 and the optical assembly 124 is accommodated.

The optical seating portion 200 can be used in an edge type display device 100 in which an optical assembly 124 is positioned on the side of the frame 130. [ Which means that it may be the place where the optical assembly 124 is received, for example, when the optical assembly 124 is disposed along the long side of the display device 100.

The optical receiver 200 may be formed on a corresponding portion of the frame 130. That is, the optical mount part 200 means that the edge area of the frame 130 may be press-processed. That is, it means that the optical receiver 200 is connected to the frame 130 in one body.

The optical receiver 200 may serve as a passage through which heat generated during the operation of the optical assembly 124 or the like is emitted. The light generating optical assembly 124 may generate heat during operation. When the heat generated in the optical assembly 124 is accumulated, malfunction of the optical assembly 124 may occur. Therefore, it is necessary to effectively discharge the heat generated in the optical assembly 124 to the outside. The heat generated in the optical assembly 124 is transferred to the substrate 122 and the heat transferred to the substrate 122 can be transmitted to the optical receiver 200. The heat transmitted to the optical receiver 200 may be transmitted to the body of the frame 130. Accordingly, it is possible to efficiently transfer heat to the frame 130 having a relatively large heat capacity, thereby effectively managing the heat of the optical seat 200.

The optical receiver 200 may be integrally formed with the frame 130. That is, as described above, it is possible to form the optical seating part 200 in the edge area of the frame 130 corresponding to the position where the optical assembly 124 is required to be coupled. Accordingly, a separate fastening member for coupling the optical seating part 200 to the frame 130 may not be required. Therefore, it is possible to omit the manufacturing process for assembling the separate fastening member and / or to omit the cost for the separate fastening member.

The optical receiver 200 can effectively transmit the heat generated in the optical assembly 124. Conventionally, a method of coupling the optical receiver 200 to a separate frame 130 is used. When the optical receiver 200 is separately configured, the optical receiver 200 needs to be in close contact with the frame 130. That is, it means that the optical receiver 200 is closely attached to the frame 130 so that the heat conduction is performed well. Therefore, a plurality of fastening members were required for close contact. In addition, if the adhesion is loosened due to the failure on the initial assembly and / or the loosening of the fastening due to the lapse of time, the heat transfer rate to the frame 130 may be lowered to cause an operation error of the optical assembly 124. This is different from the optical seat 200 that is formed integrally with the frame 130.

The optical mount part 200 includes a flange 240 extending from the frame body 132, a hook part 210 where a part of the end of the flange 240 is once bent, A joining hole 230 in which a part of the region between the frame body 132 and the flange 240 is removed can be included. The hooking part 210, the forming part 220 and the coupling hole 230 may be repeatedly formed along the optical seat 200.

The flange 240 can be a 90 degree bent portion of a particular edge of the frame body 132. That is, it means that the corner area required to be coupled with the optical assembly 124 through the press working or the like may be bent. The flange 240 may be a region to which the substrate 122 is coupled. The width W3a of the flange 240 may substantially correspond to the width W3b of the substrate 122. [

The hooking portion 210 may be a region where a part of the end of the flange 240 is once bent. For example, it means that the flange 240 in the frame body 132 can be bent once again in the direction in which the flange 240 is bent. Thus, the hooking portion 210 may be substantially in parallel with the frame body 132. [ The board 122 seated on the flange 240 can be fixed to the left and right sides by the frame body 132 and the hooking part 210. The length W1a of the hook portion 210 may substantially correspond to the length W1b of the groove 122b formed in the substrate 122. [

The forming section 220 may be a shape in which a part of the frame body 132 is pressed and protruded. What is the forming unit 220? As shown in Fig. The forming portion 220 may include a flat surface 222. The flat surface 222 can be in contact with the reflective sheet (126 in Fig. 14). That is, it means that the flat surface 222 can support the reflective sheet (126 in Fig. 14).

The coupling hole 230 may be formed between the frame body 132 and the flange 240. That is, this means that a part of the corner between the frame body 132 and the flange 240 can be removed. The length W2a of the coupling hole 230 may substantially correspond to the length W2b of the projection 122c formed on the substrate 122. [

As shown in FIG. 11, the substrate 122 may correspond to the shape of the optical receiver 200.

The substrate 122 may be long in the X direction so as to correspond to the optical receiver 200. An optical assembly 124 may be coupled to an upper surface of the substrate 122. That is, it means that a plurality of optical assemblies 124 can be arranged along the longitudinal direction of the substrate 122.

The substrate 122 may have grooves 122b and protrusions 122c along the substrate body 122a. The groove 122b corresponds to the hook 210 of the optical seat 200 and the protrusion 122c corresponds to the coupling hole 230 of the optical seat 200. [ That is, when the substrate 122 is coupled to the optical mount 200, the groove 122b, the hook 210, the protrusion 122c, and the coupling hole 230 can be naturally coupled.

12 is a diagram showing a relationship between an optical receiver and a substrate according to an embodiment of the present invention.

As shown in the figure, the optical receiver 200 and the substrate 122 according to an embodiment of the present invention may be in a mutually corresponding form.

When the center of the substrate 122 in the longitudinal direction is referred to, the projection 122c closest to the center may be located at a distance D1 from the center. The second projection 122c at the center may be spaced by a distance D2 from the nearest projection 122c and the third projection 122c at the center may be spaced by D3 from the second projection 122c. D1 may be less than D2 and / or D3. That is, the interval between the protrusions 122c at the first position in the center may be smaller than that of the other protrusions 122c. Such a structure may be a structure for coupling the substrate 122 to the optical seating part 200 without deflection.

With reference to the center in the longitudinal direction of the substrate 122, the groove 122b closest to the center may be located at a distance D4 from the center. The second groove 122b at the center may be spaced by a distance D5 from the nearest groove 122b and the third groove 122b at the center may be spaced by a distance D6 from the second groove 122b. D4 may be less than D5 and / or D6. That is, the interval between the grooves 122b at the first position from the center may be smaller than the other grooves 122b. The groove 122b furthest from the center can be positioned adjacent to the end of the substrate 122. [ That is, in order to fix the substrate 122 effectively, it means that the groove 122b can be positioned near the end of the substrate 122. [

The hook 210 located on one side of the optical seating part 200 and the coupling hole 230 located on the other side of the optical seating part 200 are mutually asymmetric with respect to the longitudinal direction of the optical seating part 200, Asymmetric positional relationship. Accordingly, the positions of the groove 122b and the projection 122c of the substrate 122 may be asymmetric.

13 and 14 are views showing a coupling relationship between a frame and an optical receiver according to an embodiment of the present invention.

As shown in these drawings, the frame 130 and the optical receiver 200 according to an embodiment of the present invention can be fastened to each other without a separate fastening member such as a screw.

As shown in Fig. 13, the substrate 122 can be approached to the optical seating portion 200 at a certain tightening angle CA. For example, the flange 240 can be approached to the flange 240 at a slant of about 45 degrees.

The substrate 122 may approach and be coupled to the optical receiver 200 at an oblique angle. For example, when the protrusion 122c is inserted into the coupling hole 230 while approaching obliquely, it means that the substrate 122 can be rotated in the clockwise direction to bring the substrate 122 into close contact with the flange 240.

The groove 122b of the substrate 122 may be inserted into the hook 210 of the optical seat 200 during the process of the substrate 122 being in close contact with the flange 240. [

The substrate 122 can be coupled to the optical seat 200 by the engagement of the protrusion 122c and the coupling hole 230 and / or the coupling of the groove 122b and the coupling portion 210. [ That is, even when a separate fastening member is not used, it means that the substrate 122 can be firmly fastened to the optical seat 200. Considering that the structures may be interdigitated by mutual scales of the respective portions of the substrate 122 and the optical receiver 200 as described above, .

The reflection sheet 126 and / or the light guide plate 128 may be coupled after the substrate 122 is coupled to the optical receiver 200, as shown in Fig.

The reflective sheet 126 and / or the light guide plate 128 may be supported by the forming unit 220. For example, it means that the reflective sheet 126 can be positioned on the flat surface 222 on the upper side of the forming section 220. [ Since the reflective sheet 126 and the like can be supported by the forming unit 220, the reflective sheet 126 can maintain a predetermined gap with the frame 130 and the like without detaching from the designed position.

The substrate 122 may be coupled to the flange 240. The substrate 122 may be coupled to the flange 240 by a structure such as the protrusion 122c so that a separate structure for coupling the substrate 122 to the optical seating portion 200 may be omitted. For example, it means that the structure of the adhesive tape or the like positioned between the substrate 122 and the steel settlement part 200 can be omitted.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
