Hereinafter, a display device according to an exemplary embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

Fig. 1 is a front view of a display device according to an exemplary embodiment of the present disclosure.

Fig. 1 illustrates a display device having a bracket fixing structure as an example, but the present disclosure is not limited thereto.

Referring to fig. 1, a display device 100 according to an exemplary embodiment of the present disclosure includes a display panel 110 displaying an image and a stand unit 120 mounted at a lower end of the display panel 110 to support a load of the display panel 110, and constructs a set of devices.

The display device 100 having the stand fixing structure is used as a stand structure to be equipped on a bottom surface of a predetermined space, such as a computer monitor or a television.

Although not specifically shown, the display device 100 according to an exemplary embodiment of the present disclosure may further include a cover unit surrounding the outside of the display panel 110, and the cover unit may be divided into a front and a rear. For convenience of description, both the display panel 110 and the cover unit are included to be referred to as a display unit 150.

Here, the cover unit may include a front cover 135 covering a portion of the lower end of the display panel 110 and a bottom cover 155 (also referred to as a rear cover) surrounding the rear surface and side surfaces of the display panel 110. The rear surface extends in a first direction (e.g., a vertical direction) and the side surfaces extend in a second direction (e.g., a horizontal direction) different from the first direction. The lower end of the bottom cover 155 extends from the lower end of the rear surface of the display panel in the first direction so that an inner space is formed in the display device. The main board is in the internal space. The main board is not overlapped with the display panel. Although the cover unit is omitted in fig. 1, the cover unit may further include a top case surrounding a front edge of the display panel 110 to be coupled to a side surface of the bottom cover 155. In the present disclosure, the top case is omitted in order to achieve a narrow bezel.

The display panel 110 is a panel for displaying an image to a user.

In the display panel 110, a display element that displays an image, a driving element that drives the display element, wiring that transmits various signals to the display element, and the like may be provided. The display element may be defined in various ways according to the type of the display panel 110, for example, when the display panel 110 is a liquid crystal display panel, the display panel 110 may be configured to include upper and lower substrates and a liquid crystal layer interposed therebetween.

Hereinafter, it is assumed that the display panel 110 is a liquid crystal display panel, but the present disclosure is not limited thereto. For example, when the display panel 110 is an organic light emitting display panel, the display element may be an organic light emitting diode including an anode, an organic light emitting layer, and a cathode.

The display panel 110 may be constructed of upper and lower substrates and a liquid crystal layer interposed therebetween. The liquid crystal display device is a flat panel display device that displays an image by adjusting light transmittance according to the arrangement of liquid crystal molecules of a liquid crystal layer when light is transmitted.

On the rear side of the display panel 110, a backlight unit providing light and a bottom cover 155 accommodating the backlight unit and the display panel 110 are provided. At this time, the backlight unit may include a light source and an optical unit that provides light generated from the light source to the display panel 110. The display panel 110 will be described in more detail with reference to fig. 2 to 5.

The bottom cover 155 may surround the rear surface and the side surfaces of the display panel 110, and accommodate the backlight unit and the display panel 110 laminated from the lowermost layer.

In some embodiments, the display device 100 further includes a bracket unit 120 (also referred to as a bracket) attached to a lower end of the bottom cover. Meanwhile, the stand unit 120 may support the display unit 150 to stand on the platform.

For this, the stand unit 120 may be constructed of a fixing plate (not shown), a tilt adjusting unit (not shown), a supporting unit 121, and a bottom plate 122. A fixing plate is connected to a rear surface of the bottom cover 155, a tilt adjusting unit is integrally formed with the fixing plate to adjust a vertical angle (tilt) of the display unit 150, and a supporting unit 121 is coupled to the tilt adjusting unit to support the display unit 150. Further, a bottom plate 122 is provided on the bottom surface of the supporting unit 121 to support the load of the display unit 150.

The fixing plate may have a plurality of through holes to fix it on the rear surface of the bottom cover 155, but is not limited thereto.

Even though not shown, when the rear surface of the bottom cover 155 and the holder unit 120 are assembled, a plurality of fastening protrusions may be formed on the lower end of the fixing plate of the holder unit 120 to restrain the holder unit 120 from moving on the rear surface of the bottom cover 155. Further, a fastening protrusion groove coupled corresponding to the fastening protrusion of the fixing plate may be formed in a predetermined position of the bottom cover 155 to which the bracket unit 120 is fixed by a screw, but the present disclosure is not limited thereto.

Meanwhile, in the exemplary embodiment of the present disclosure, the curved structure of the bottom cover 155 is applied to the side surface of the display panel 110, and the rear cover is deleted, but one side of the bottom cover 155 is extended to dispose the source printed circuit board and the main board therein. That is, the three sides of the left, right and top ends of the bottom cover 155 are bent inward by about 180 degrees in the display panel 110 to form an inner curled structure (or hemming structure), and bent in opposite directions by about 90 degrees to form an "L" -shaped bent structure. In addition, the lower end of the bottom cover 155 extends and the side portion is bent inward by about 180 degrees in the display panel 110 to form an inner curled structure to dispose the source printed circuit board and the main board in the extended bottom cover 155. By doing so, the overall thickness is reduced to achieve a slim design.

In particular, according to the present disclosure, the rear cover is deleted, and only a minimum structure for hinge fixation is reserved on the rear surface of the display unit 150 to achieve a compact and differentiated design.

That is, in the related art, all circuit components such as a main board and a hinge structure are provided on the rear surface of the display unit so that the thickness is thick, which will be described with reference to fig. 2.

Fig. 2 is a side view of a display device according to a comparative embodiment.

Referring to fig. 2, the display device according to the comparative embodiment includes a display panel 10 displaying an image and a stand unit 20 installed below the display panel 10 to support a load of the display panel 10.

The stand unit 20 is constructed of a fixing plate 23 coupled to a rear surface of the bottom cover 55, a tilt adjusting unit 24 integrally formed with the fixing plate 23 to adjust a vertical angle of the display unit 50, a supporting unit 21 coupled to the tilt adjusting unit 24 to support the display unit 50, and a bottom plate 22 disposed on a bottom surface of the supporting unit 21.

At this time, in the display device according to the comparative embodiment, all circuit components such as the main board, the source printed circuit board, the cable connector, and the hinge structure are disposed on the rear surface of the display unit 50 such that the thickness D' is thick. Further, the lower end of the display unit 50 protrudes toward the rear surface, so that the realization of a slim design is restricted.

Furthermore, since the thickness D' of the whole set is thick, the size and design of the stand unit 20 are limited.

In addition, the number of assembly parts (such as screws or nuts) for coupling the bottom cover 55 and the circuit parts and the holder unit 22 is increased, so that the cost of molding and processing the bottom cover 55 is increased. In addition, guide panels are used for assembly, complicating the process and increasing the costs for molding and tooling.

Accordingly, in the present disclosure, the curved structure of the bottom cover 155 is applied to the side surface of the display panel 110, and the side surface of the bottom cover 155 extends to dispose the source printed circuit board and the main board in the bottom cover 155. By so doing, the overall thickness is reduced to achieve a slim design, which will be described in detail with reference to fig. 3 to 8.

Fig. 8 is a sectional view taken along line B-B' of fig. 7.

Fig. 4 shows a side view of the display unit 150 of fig. 3 seen from the right side. As compared with the comparative embodiment, it can be understood that the rear cover is deleted, and circuit components such as the source printed circuit board 119 and the main board 140 are disposed in the bottom cover 155 so that the thickness is greatly reduced.

Referring to fig. 3 to 8, the display unit 150 of the exemplary embodiment of the present disclosure may include a display panel 110 displaying an image, a bottom cover 155 surrounding a rear surface and side surfaces of the display panel 110, and various circuit components disposed in the bottom cover 155.

First, the display panel 110 may be constructed of upper and lower substrates 111 and 112 and a liquid crystal layer (not shown) interposed between the upper and lower substrates 111 and 112.

Hereinafter, it is assumed that the display panel 110 is a liquid crystal display panel, but as described above, the present disclosure is not limited thereto. When the display panel 110 is an organic light emitting display panel, the display element may be an organic light emitting diode including an anode, an organic light emitting layer, and a cathode.

Hereinafter, even though not shown in the drawings, under the assumption of the active matrix type, a plurality of gate lines and data lines intersect to define sub-pixels on an inner surface of the lower substrate 112, which is generally referred to as an array substrate or a first substrate. Further, a thin film transistor is provided in each of the intersections to be connected to a pixel electrode formed in each of the sub-pixels.

Further, red (R), green (G), and blue (B) color filters corresponding to the sub-pixels, a black matrix surrounding the color filters and blocking non-display elements such as gate lines, data lines, and thin film transistors, and a common electrode covering them are disposed on the inner surface of the upper substrate 111. The upper substrate is referred to as a color filter substrate or a second substrate. At this time, when the liquid crystal display panel is an in-plane switching (IPS) mode or a Fringe Field Switching (FFS) mode, the common electrode may be formed on the lower substrate 112.

An upper polarizing plate 114a and a lower polarizing plate 114b that selectively transmit only specific light may be attached to outer surfaces of the upper and lower substrates 111 and 112, respectively.

A sealing unit 113, such as a sealant, may be disposed on edge side surfaces of the upper and lower substrates 111 and 112 except for the lower side to seal the side surfaces of the upper and lower substrates 111 and 112. The sealing unit 113 is also used to fix the upper and lower substrates 111 and 112 so that the top case of the related art may be omitted, whereby the bezel width may be reduced.

Meanwhile, the display panel 110 may include an active area AA and a non-active area NA.

The effective area AA is an area in which an image is displayed in the display panel 110.

In the active area AA, a plurality of sub-pixels configuring a plurality of pixels and a circuit for driving the plurality of sub-pixels may be provided. The plurality of sub-pixels are the smallest unit constructing the effective area AA, and a display element may be disposed in each of the plurality of sub-pixels. The plurality of sub-pixels may construct a pixel. For example, in each of the plurality of sub-pixels, a thin film transistor as a switching element may be provided, but is not limited thereto. Further, a circuit for driving a plurality of sub-pixels may include a driving element, wiring, and the like. For example, the circuit may be configured of a thin film transistor, a storage capacitor, a gate line, a data line, or the like, but is not limited thereto.

The non-effective area NA is an area where an image is not displayed.

Although it is shown in fig. 3 that the non-effective area NA surrounds the quadrangular effective area AA, the shapes and arrangements of the effective area AA and the non-effective area NA are not limited to the example shown in fig. 3.

In other words, the active area AA and the inactive area NA may have shapes suitable for the design of the following electronic devices: the electronic device is provided with a display device. For example, additional exemplary shapes of the active area AA may be pentagonal, hexagonal, circular, elliptical, etc.

In the non-effective area NA, various wirings and circuits for driving the liquid crystal display element of the effective area AA may be provided. For example, in the non-active area NA, wirings or driving ICs (such as a gate driver IC or a data driver IC) transmitting signals to a plurality of sub-pixels and circuits of the active area AA may be provided, but is not limited thereto.

In addition, the display device 110 may further include various additional elements for generating various signals or driving pixels in the display area AA. Additional components for driving the pixels may include inverter circuits, multiplexers, electrostatic discharge circuits (ESD), etc. The display panel 110 may further include additional elements associated with functions other than the function of driving the pixels. For example, the display panel 110 may include additional elements that provide touch sensing functionality, user authentication functionality (e.g., fingerprint recognition), multi-stage pressure sensing functionality, haptic feedback functionality, and the like. The additional elements may be located in external circuits connected to the inactive area NA and/or the connection interface.

The display unit 150 may further include a flexible film 118 and a source printed circuit board 119.

The flexible film 118 is a film in which various members are provided on a base film having ductility. Specifically, the flexible film 118 is a film that supplies signals to a plurality of subpixels and circuits of the display area AA and may be electrically connected to the display panel 110. The flexible film 118 is disposed at one end of the non-display area NA of the display panel 110 to supply power voltages or data voltages to the plurality of sub-pixels and circuits of the display area AA. Meanwhile, the number of the flexible films 118 may vary according to design, and is not limited thereto.

For example, a driving IC such as a data driver IC may be provided on the flexible film 118. The driving IC is a component that processes a data signal for displaying an image, a driving signal for processing the data signal, and the like. Depending on the mounting method, the driving IC may be provided by a Chip On Glass (COG), a Chip On Film (COF), a Tape Carrier Package (TCP), or the like.

Further, a source printed circuit board 119 is provided at one end of the flexible film 118 to be connected to the flexible film 118. The source printed circuit board 119 is a component that supplies signals to the drive ICs. The source printed circuit board 119 supplies various signals such as a driving signal or a data signal to the driving IC. For example, a data driver generating data signals may be mounted in the source printed circuit board 119, and the generated data signals may be supplied to a plurality of sub-pixels and circuits of the display panel 110 through the flexible film 118. The number of source printed circuit boards 119 may vary according to design, and is not limited thereto.

In an exemplary embodiment of the present disclosure, the source printed circuit board 119 is disposed at a lower end of the display panel 110 in a direction substantially parallel to the display panel 110. That is, the source printed circuit board 119 may be disposed to lie on the lower end of the display panel 110 in a direction substantially parallel to the display panel 110.

In some embodiments, the display device 100 further includes a backlight device (also referred to as a backlight unit) on the rear surface of the display panel 110. The backlight device is configured to provide light to the display panel. Meanwhile, on the rear surface of the display panel 110 constructed as described above, a backlight unit providing light and a bottom cover 155 accommodating the backlight unit and the display panel 110 may be provided. The bottom cover 155 surrounds the rear and side surfaces of the display panel 110 and the display panel, and the backlight device is on the bottom cover 155.

The backlight unit may correspond to one or more of the reflective plate 153, the light guide plate 151, and/or the plurality of optical sheets 152 shown in fig. 6, and/or other components not shown in fig. 6. The backlight unit may include: the display panel 110 includes an LED array assembly including a light source accommodated in a bottom cover 155, a light guide plate 151 providing a surface light source to the display panel 110 through the light source, a reflection plate 153 disposed on a rear surface of the light guide plate 151, and a plurality of optical sheets 152. A plurality of optical sheets 152 are disposed on the top surface of the light guide plate 151. However, the backlight unit is not limited thereto.

For example, the light source may be configured as an LED package in which an LED is mounted, and may be disposed in a light incident area of the light guide plate 151. The LED array assembly 157 may include an LED package and an LED printed circuit board.

An LED fixing plate 158 to mount the LED package may be disposed on the rear surface of the LED array assembly 157.

The LED fixing plate 158 may extend to the outside. That is, the LED fixing plate 158 may extend to a lower direction of the bottom cover 155 in a direction substantially parallel to the lower portion 155a of the bottom cover 155. The lower portion 155a extends in a first direction. The lower portion 155a includes a lower end of the bottom cover 155. At this time, the LED fixing plate 158 extending to the lower direction of the bottom cover 155 may be disposed in the bottom cover 155.

Some configurations of the backlight device may be fixed by the guide panel 156, and the guide panel 156 may be fixed by the LED fixing plate 158.

In an exemplary embodiment of the present disclosure, the display panel 110 and the backlight unit are implemented as a one-piece design by means of the bottom cover 155. In the related art, the appearance is formed by two configurations of the guide panel and the bottom cover. However, in the exemplary embodiment of the present disclosure, the guide panel 156 is disposed only under the display panel 110 for fixing a partial configuration of the backlight, i.e., the optical sheet 152. The bottom cover 155 covers all rear and side surfaces of the backlight unit and the display panel 110 to form an external appearance.

With this configuration, according to the present disclosure, coloring tasks due to the material difference of the guide panel 156 and the bottom cover 155 are unnecessary, so that the process can be simplified.

Meanwhile, light traveling to the light incident surface of the light guide plate 151 may be emitted toward the upper portion where the display panel 110 is disposed while undergoing several total reflection processes inside the light guide plate 151.

At this time, the light guide plate 151 may include a pattern having a specific shape on the rear surface to provide a uniform surface light source. The pattern may be constructed in various patterns such as an elliptical pattern, a polygonal pattern, or a hologram pattern to guide light incident thereto, and the pattern may be formed on the lower surface of the light guide plate 151 by a printing method or an injection method.

The optical sheet 152 may be configured of a diffusion sheet for diffusing surface light emitted from the light guide plate 151, a prism sheet for condensing light, and a protective sheet performing auxiliary functions for protecting the prism sheet and diffusing light, but is not limited thereto.

In some embodiments, each of the one or more side portions 155b is bent perpendicularly from the lower portion of the bottom cover and extends in the second direction. In some embodiments, each of the one or more side portions 155b may be configured to be bent perpendicular to four edges of the lower portion 155a other than the corners, but is not limited thereto. In some embodiments, lower portion 155a includes a plurality of edges, and each of the plurality of edges of the lower portion is connected to a corresponding side 155b that is perpendicularly bent from lower portion 155a.

Further, the bottom cover 155 according to the exemplary embodiment of the present disclosure may form an inner curled structure, i.e., inner side portions 155c and 155c', by bending the four side portions 155b inward toward the inside of the display panel 110 by about 180 degrees. In some embodiments, each of the inner side portions 155c or 155c' is bent inward from the corresponding side portion 155b toward the display panel, and extends in the second direction such that the inner side portion is parallel to the corresponding side portion 155b. In some embodiments, side 155b of bottom cover 155 is connected to a corresponding inner side 155c or 155c' that is bent inward from side 155b.

As described above, according to the present disclosure, the hemming structure and the bending structure are applied to three surfaces or four surfaces to enhance rigidity and protect the side surfaces of the adhesive tape 115.

The three inner side portions 155c of the bottom cover 155 bent in an "L-shape" may configure the seating unit 155d.

Here, corners of the bottom cover 155 are cut to bend four edges, and then a primary bending process is performed on the four edges to form the side 155b. After forming the side parts 155b on the four surfaces of the bottom cover 155, a secondary bending process is performed on the three side parts 155b of the left, right and upper ends to form a seating unit 155d having an L-shaped bent structure. Next, three bending processes are performed on the four side portions 155b to form inner side portions 155c and 155c' having an inner curl (or hemming) structure.

The rear edge of the display panel 110 may be seated in the seating unit 155 d.

The display panel 110 may be attached to the seating unit 155d of the bottom cover 155 by the adhesive tape 115.

The adhesive tape 115 may have a frame shape along the left, right, and upper edges of the display panel 110 except for the lower end, but is not limited thereto.

The side portion 155b and the inner side portions 155c and 155c' of the bottom cover 155 may contact each other, but are not limited thereto.

The inner side portions 155c and 155c' of the bottom cover 155 may have a smaller height than the side portion 155 b.

The three seating units 155d of the left, right and upper ends may extend in a direction substantially parallel to the lower portion 155a, but are not limited thereto.

Meanwhile, the lower end of the bottom cover 155 according to the exemplary embodiment of the present disclosure extends toward the holder unit to form a predetermined space between the other end of the guide panel 156 and the inner side portion 155c' of the lower end of the bottom cover 155. Accordingly, the source printed circuit board 119 and the main board 140 are disposed in the inner space.

Accordingly, the entire thickness of the display unit 150 is reduced to achieve a slim design. In addition, the rear cover is deleted, and only a minimum structure for hinge fixing is reserved on the rear surface of the display unit 150 to achieve a compact and differentiated design. That is, in the related art, circuit components such as a source printed circuit board and a main board are disposed on the rear surface of the bottom cover to protrude to the rear side, and the rear cover is necessary to protect the circuit components. In this case, since the rear cover is thick, the thickness of the display unit is not uniform, so that the elegance of the design is halved. In contrast, in the present disclosure, the rear cover is deleted, and circuit components such as the source printed circuit board 119 and the main board 140 are disposed in the inner space of the bottom cover 155. Accordingly, it can be understood that the thickness of the display unit 150 is uniformly about 4.5 to 6mm, and the thickness of the lower end is reduced by about 90% as compared with the related art. Further, a design of the display unit 150 having a flat rear surface may be implemented. That is, a compact and differentiated design that does not form any shape or any structure on the rear surface of the display unit 150 can be achieved.

The main board 140 disposed in the bottom cover 155 may be connected to the LED fixing board 158 by a first cable (not shown), and the main board 140 and the source printed circuit board 119 may be connected to each other by a second cable (not shown).

The first and second cables may be embedded in the inner space of the bottom cover 155.

In addition, the top and side surfaces of the main board 140 disposed in the inner space of the bottom cover 155 may be covered by the front cover 135 and the source printed circuit board 119 disposed above the main board 140, and a portion of the lower end of the display panel 110 may be covered by the front cover 135.

Meanwhile, according to the present disclosure, the source printed circuit board is disposed inside the bottom cover, and the main board is covered by the rear cover. Accordingly, even if the rear cover is applied, the protrusion toward the rear surface may be minimized (or at least reduced) to minimize (or reduce) the thickness of the display device, which will be described in detail with reference to fig. 9 to 15.
