Abstract
Description
Technical Field
[0001] Embodiments of the present invention relate to a display device. Background Technology
[0002] Flat panel displays are replacing cathode ray tube (CRT) displays due to their advantages such as being lightweight and thin. Representative examples of such flat panel displays include liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays.
[0003] A flat panel display device may include a display panel for displaying images and a sound generator for providing sound. The sound generator outputs sound by causing the display panel to vibrate. The display panel may be divided into multiple zones, and multiple sound generators may be respectively disposed in a corresponding zone of each zone. Therefore, the flat panel display device can achieve stereo or surround sound through multiple channels. Summary of the Invention
[0004] Embodiments of the present invention provide a display device that includes multiple audio channels and has improved sound quality.
[0005] Additional features of the invention will be set forth in the following description and will be apparent in part from the description or may be learned by practice of the invention.
[0006] The display device in the embodiment includes: a display panel including a first area and a second area; a sound generator disposed on the display panel in at least one of the first area and the second area; a dividing member disposed on the display panel at the boundary between the first area and the second area and extending in a predetermined direction; and a blocking member disposed on the display panel in at least one of the first area and the second area and spaced apart from the dividing member.
[0007] In one embodiment, the blocking member may extend in the predetermined direction.
[0008] In one embodiment, the length of the blocking member in the predetermined direction may be less than the length of the dividing member in the predetermined direction.
[0009] In one embodiment, the blocking member may include a plurality of blocking patterns spaced apart from each other in the predetermined direction.
[0010] In one embodiment, at least a portion of the blocking member may be tilted relative to the dividing member.
[0011] In one embodiment, the display device may further include a support member disposed on the display panel and surrounding the first area and the second area.
[0012] In one embodiment, the blocking member may be spaced apart from the supporting member. The dividing member may contact the supporting member.
[0013] In one embodiment, the display device may further include an auxiliary blocking member facing the blocking member and symmetrical to the blocking member relative to the sound generator. The auxiliary blocking member may be spaced apart from the support member.
[0014] The display device in the embodiment includes: a display panel including a first area, a second area, and a third area, wherein the second area is disposed between the first area and the second area; a sound generator disposed on the display panel in at least one of the first area to the third area; a first dividing member disposed on the display panel at the boundary between the first area and the second area; a second dividing member disposed on the display panel at the boundary between the second area and the third area; a first blocking member disposed on the display panel in at least one of the first area and the second area, and spaced apart from the first dividing member; and a second blocking member disposed on the display panel in at least one of the second area and the third area, and spaced apart from the second dividing member.
[0015] The display device in the embodiment includes: a display panel including a first area, a second area, a third area, and a fourth area arranged in two rows and two columns; a sound generator disposed on at least one of the first to fourth areas on the display panel; a first dividing member extending in a first direction and disposed on the display panel at the boundary between the first and second areas, and at the boundary between the third and fourth areas; a second dividing member extending in a second direction intersecting the first direction and disposed on the display panel at the boundary between the first and third areas, and at the boundary between the second and fourth areas; and a first blocking member. The display panel is provided with a second blocking member, which is disposed in at least one of the first and second zones and spaced apart from each of the first and second dividing members; a third blocking member is disposed in at least one of the first and third zones and spaced apart from each of the first and second dividing members; and a fourth blocking member is disposed in at least one of the second and fourth zones and spaced apart from each of the first and second dividing members.
[0016] The display device in this embodiment may include a blocking member spaced apart from each of the segmenting member and the supporting member. Therefore, the display device can attenuate sound waves generated from the sound generator in the space between the blocking member and the segmenting member. Thus, the display device can prevent or reduce interference or distortion of sound between channels, and can prevent or reduce sound pressure level reduction caused by reflected waves or standing waves. Furthermore, since the area of the display panel in which it vibrates can be widened, the sound quality of the display device, including sound pressure level, can be improved.

[0032] Exemplary, non-limiting embodiments will be more clearly understood from the following detailed description and in conjunction with the accompanying drawings.
[0033] What will be understood is that when an element is said to be "on" another element, it can be directly on the other element, or there can be intermediate elements in between. Conversely, when an element is said to be "directly" on another element, there are no intermediate elements.
[0034] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or section from another. Therefore, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of this document.
[0035] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms, including “at least one,” unless the context clearly indicates otherwise. “Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It will be further understood that, when used in this specification, the terms “comprising” and / or “including,” or “containing” and / or “comprising” indicate the presence of the stated features, areas, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, areas, integers, steps, operations, elements, components, and / or groups thereof.
[0036] Furthermore, relative terms such as “lower” or “bottom” and “upper” or “top” are used in the text to describe the relationship between one element and another as shown in the figures. It will be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. In one embodiment, when the device in one of the figures is flipped, an element described as being “below” the other element will then be oriented “above” the other element. The exemplary term “lower” can therefore include both “lower” and “upper” orientations, depending on the specific orientation in the figure. Similarly, when the device in one of the figures is flipped, an element described as being “below” or “under” the other element will then be oriented “above” the other element. The exemplary term “below” or “under” can therefore include both “above” and “below” orientations.
[0037] Taking into account the relevant measurements and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system), as used herein, “approximately” or “about” includes the value and the average value within an acceptable range of deviation from the particular value as determined by those skilled in the art. For example, “approximately” may mean within one or more standard deviations of the value, or within ±30%, 20%, 10%, or 5% of the value.
[0038] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It will be further understood that terms such as those defined in common dictionaries should be interpreted as having meanings consistent with their meanings in the relevant field and in the context of this invention, and should not be interpreted in an idealized or overly formal sense unless expressly defined herein.
[0039] Embodiments are described herein with reference to cross-sectional views illustrating idealized embodiments. Therefore, variations from the illustrated shapes are contemplated, for example, due to manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but should include, for example, shape deviations arising from manufacturing processes. In one embodiment, regions illustrated or described as flat may generally have rough and / or non-linear characteristics. Furthermore, illustrated acute angles may be rounded. Therefore, the regions illustrated in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shapes of the regions, nor are they intended to limit the scope of the claims.

Figure 5 and Figure 6 This is an example of a display panel due to... Figure 3 A cross-sectional view of the sound generator vibrating. Figure 7 This is an example Figure 1 A plan view of an embodiment of the display device.
[0041] See Figures 1 to 7 An embodiment of the display device 10 may include a display panel 100, at least one sound generator 200, a dividing member 310, a supporting member 320, at least one blocking member 330, and a covering member 400.
[0042] The display panel 100 for displaying images can be provided in various shapes. In one embodiment, such as... Figure 1 As shown, the display panel 100 may have a quadrilateral (e.g., rectangular) shape in a plan view. In one embodiment, the display panel 100 may have a short side extending in a first direction DR1 and a long side extending in a second direction DR2 intersecting the first direction DR1. In another embodiment, the display panel 100 may have different polygonal, circular, or elliptical planar shapes.
[0043] The display panel 100 may include a first surface 101 for displaying images and a second surface 102 opposite to the first surface 101. A sound generator 200 may be disposed on the second surface 102 of the display panel 100. In one embodiment, the sound generator 200 may contact the second surface 102 of the display panel 100 and may vibrate the display panel 100 to output sound, for example.
[0044] In one embodiment, the display device 10 may further include a sound driver (not shown) electrically connected to the sound generator 200. The sound driver can output a sound signal to the sound generator 200. In one embodiment, the sound signal may include, for example, a first driving voltage and a second driving voltage. The sound driver can be electrically connected to the sound generator 200 via a first sound line (not shown) and a second sound line (not shown). The sound generator 200 can receive the first driving voltage via the first sound line and the second driving voltage via the second sound line. In one embodiment, the first driving voltage and the second driving voltage can be alternating current (“AC”) voltages that oscillate between positive and negative levels relative to a predetermined reference level. In one embodiment, the sound driver can generate a sound signal based on sound data received from an external device and, for example, output the sound signal to the sound generator 200.
[0045] The sound generator 200 can output sound by vibrating the display panel 100 based on an audio signal input from a sound driver. In one embodiment, the sound generator 200 can, for example, vibrate the display panel 100 on a third direction DR3 perpendicular to the second surface 102 based on a first driving voltage and a second driving voltage. In one embodiment, the sound generator 200 can be, for example, an exciter that uses a voice coil to generate magnetic force and thereby vibrate the display panel 100. In another embodiment, the sound generator 200 can be a piezoelectric element that contracts or expands according to a voltage applied thereto and thereby vibrates the display panel 100.
[0046] In one embodiment, such as Figures 3 to 6 As shown, the sound generator 200 can be an exciter that uses a voice coil to generate magnetic force and thereby cause the display panel 100 to vibrate. In one embodiment, the sound generator 200 may include, for example, a magnet 201, a spool 202, a voice coil 203, and a damper 204.
[0047] Magnet 201 can be a permanent magnet, and sintered magnets such as barium ferrite magnets can be used. In one embodiment, magnet 201 may be provided, for example, as an iron oxide (Fe2O3) magnet, a barium carbonate (BaCO3) magnet, a neodymium magnet, a strontium ferrite magnet with improved magnetic components, or a cast alloy magnet of aluminum, nickel (Ni), or cobalt (Co). In one embodiment, the neodymium magnet may be, for example, a neodymium iron boron (Nd-Fe-B) magnet.
[0048] The magnet 201 may include a plate 201a, a central protrusion 201b projecting from the center of the plate 201a, and an edge protrusion 201c projecting from the edge of the plate 201a. In one embodiment, the plate 201a of the magnet 201 may, for example, be fixed to a portion of a cover member 400. The central protrusion 201b and the edge protrusion 201c may be spaced apart from each other. Thus, a space may be defined between the central protrusion 201b and the edge protrusion 201c.
[0049] In one embodiment, for example, the central protrusion 201b of the magnet 201 may have N-pole magnetism, and the plate 201a and the edge protrusion 201c may have S-pole magnetism. Therefore, an external magnetic field can be generated between the central protrusion 201b and the plate 201a, and between the central protrusion 201b and the edge protrusion 201c.
[0050] The spool 202 may be provided in a cylindrical shape. A central protrusion 201b of the magnet 201 may be disposed within the spool 202. That is, the spool 202 may be configured to surround the central protrusion 201b of the magnet 201. An edge protrusion 201c of the magnet 201 may be disposed on the outer side of the spool 202. That is, the edge protrusion 201c of the magnet 201 may be configured to surround the spool 202. Spaces may be defined between the spool 202 and the central protrusion 201b of the magnet 201, and between the spool 202 and the edge protrusion 201c of the magnet 201.
[0051] In one embodiment, the spool 202 may comprise pulp or paper processing materials, Al, Mg, or alloys thereof, synthetic resins such as polypropylene, or polyamide-based fibers. In one embodiment, the end of the spool 202 may be attached to, for example, a second surface 102 of the display panel 100.
[0052] A voice coil 203 can be wound around the outer peripheral surface of a spool 202. A first sound line can be connected to the end of the voice coil 203 adjacent to the end of the spool 202. A second sound line can be connected to the other end of the voice coil 203. A first driving voltage can be applied to the first sound line. A second driving voltage can be applied to the second sound line. Therefore, current can flow in the voice coil 203, generating an applied magnetic field around the voice coil 203. In one embodiment, for example, the direction of the current flowing in the voice coil 203 when the first driving voltage is positive and the second driving voltage is negative can be opposite to the direction of the current flowing in the voice coil 203 when the first driving voltage is negative and the second driving voltage is positive. Therefore, the N and S poles of the applied magnetic field can be changed due to the alternating driving of the first and second driving voltages. Therefore, attractive and repulsive forces can act alternately on the magnet 201 and the voice coil 203. Therefore, the spool 202 around which the voice coil 203 is wound can be as follows: Figure 5 and Figure 6 As shown, it reciprocates on the third-direction DR3. Therefore, the display panel 100 can vibrate on the third-direction DR3 and can output sound.
[0053] A damper 204 may be disposed between the top of the spool 202 and the edge protrusion 201c of the magnet 201. The damper 204 can contract or expand according to the vertical movement of the spool 202, and thus control the vertical vibration of the spool 202. That is, the vertical movement of the spool 202 can be limited by the restoring force of the damper 204. In one embodiment, when the spool 202 vibrates above or below a predetermined height, the spool 202 may, for example, return to its original position due to the restoring force of the damper 204.
[0054] In one embodiment, such as Figure 2 and Figure 7As shown, the display panel 100 may include a first zone A1 and a second zone A2. A sound generator 200 may be disposed on the display panel 100 in at least one of the first zone A1 and the second zone A2. In one embodiment, for example, a first sound generator 210 may be disposed on the display panel 100 in the first zone A1, and a second sound generator 220 may be disposed in the second zone A2. Therefore, the display device 10 can provide 2.0 channel stereo sound to the user.
[0055] The first sound generator 210 can vibrate a first area A1 of the display panel 100 based on a first sound signal input from a sound driver. Since the vibration of the first area A1 of the display panel 100 generates a first sound wave, a first sound can be output. The second sound generator 220 can vibrate a second area A2 of the display panel 100 based on a second sound signal input from a sound driver. Since the vibration of the second area A2 of the display panel 100 generates a second sound wave, a second sound can be output. Therefore, the display device 10 can provide 2.0 channel stereo sound to the user.
[0056] The dividing member 310 may be disposed on the display panel 10 between the first area A1 and the second area A2. In one embodiment, the dividing member 310 may be disposed on the second surface 102 of the display panel 100 at the boundary between the first area A1 and the second area A2. That is, the display panel 100 may be divided into the first area A1 and the second area A2 by the dividing member 310.
[0057] In one embodiment, such as Figure 7 As shown, the dividing member 310 may extend, for example, in the first direction DR1. That is, the second region A2 may be provided from the first region A1 in the second direction DR2.
[0058] In one embodiment, the dividing member 310 may include, for example, polyurethane, polyolefin, silicone, rubber, aerogel, etc. In another embodiment, the dividing member 310 may include single-sided tape, double-sided tape, acrylic adhesive, silicone adhesive, etc.
[0059] A support member 320 may be disposed between the display panel 100 and the cover member 400. In one embodiment, the support member 320 may be disposed, for example, at the edge of the display panel 100. That is, the support member 320 may be disposed on the display panel 100 to completely surround the first region A1 and the second region A2. In one embodiment, for example, one surface of the support member 320 may contact the second surface 102 of the display panel 100, and another surface of the support member 320 may contact the surface of the cover member 400. Therefore, a space may be defined between the display panel 100 and the cover member 400.
[0060] In one embodiment, the support member 320 may, for example, comprise a material substantially the same as that of the dividing member 310. In one embodiment, the support member 320 may comprise, for example, polyurethane, polyolefin, silicone, rubber, aerogel, etc. In one embodiment, the support member 320 may comprise single-sided tape, double-sided tape, acrylic adhesive, silicone adhesive, etc.
[0061] The support member 320 is accessible to the dividing member 310. In one embodiment, as... Figure 7 As shown, the dividing member 310 extending in the first direction DR1 may contact, for example, the first long side 321 and the second long side 322 of the support member 320. Each of the first long side 321 and the second long side 322 may extend in the second direction DR2.
[0062] The blocking member 330 may be disposed on the display panel 100 in at least one of the first area A1 and the second area A2. In one embodiment, the blocking members 330a and 330b may be disposed on the display panel 100 in the first area A1 and the second area A2, respectively. Each of the blocking members 330a and 330b may be spaced apart from the dividing member 310 and the supporting member 320.
[0063] In one embodiment, the blocking member 330 may, for example, comprise a material substantially the same as that of the dividing member 310. In one embodiment, the blocking member 330 may comprise, for example, polyurethane, polyolefin, silicone, rubber, aerogel, etc. In one embodiment, the blocking member 330 may comprise single-sided tape, double-sided tape, acrylic adhesive, silicone adhesive, etc.
[0064] Each of the blocking members 330a and 330b can be configured to be closer to the dividing member 310 than each of the first sound generator 210 and the second sound generator 220. In one embodiment, for example, the distance between the blocking member 330a and the dividing member 310 in the second direction DR2 in the first region A1 may be less than the distance between the blocking member 330a and the first sound generator 210 in the second direction DR2. Similarly, the distance between the blocking member 330b and the dividing member 310 in the second region A2 in the second direction DR2 may be less than the distance between the blocking member 330b and the second sound generator 220 in the second direction DR2.
[0065] In one embodiment, such as Figure 7As shown, each of the blocking members 330a and 330b may extend in the first direction DR1 and may be spaced apart from the dividing member 310, for example. That is, each of the blocking members 330a and 330b may be parallel to the dividing member 310 and may be spaced apart from the dividing member 310 by a predetermined distance. Therefore, first spaces S1a and S1b may be defined between the blocking member 330a and the dividing member 310, and between the blocking member 330b and the dividing member 310, respectively.
[0066] In one embodiment, each of the blocking members 330a and 330b may extend in the first direction DR1 and may be spaced apart from the support member 320, for example. That is, each of the blocking members 330a and 330b may be spaced apart from the first long side 321 and the second long side 322 of the support member 320. The length of each of the blocking members 330a and 330b in the first direction DR1 may be less than the length of the dividing member 310 in the first direction DR1. In addition, the length of each of the blocking members 330a and 330b in the first direction DR1 may be less than the distance between the first long side 321 and the second long side 322 of the support member 320 in the first direction DR1.
[0067] In one embodiment, for example, a first opening OP1a may be defined between the first long side 321 and the end of the blocking member 330a adjacent to the first long side 321, and between the second long side 322 and the other end of the blocking member 330a adjacent to the second long side 322. A first opening OP1b may be defined between the first long side 321 and the end of the blocking member 330b adjacent to the first long side 321, and between the second long side 322 and the other end of the blocking member 330b adjacent to the second long side 322.
[0068] At least a portion of the first sound wave generated by the first sound generator 210 in the first zone A1 can advance to the blocking member 330a or the first opening OP1a. The portion of the first sound wave advancing to the blocking member 330a can be attenuated as it passes through the blocking member 330a. A portion of the first sound wave advancing to the first opening OP1a can be incident through the first opening OP1a into the first space S1a between the blocking member 330a and the dividing member 310, and can be attenuated in the first space S1a.
[0069] At least a portion of the second sound wave generated by the second sound generator 220 in the second zone A2 may advance to the blocking member 330b or the first opening OP1b. A portion of the second sound wave advancing to the blocking member 330b may be attenuated as it passes through the blocking member 330b. A portion of the second sound wave advancing to the first opening OP1b may be incident through the first opening OP1b into the first space S1b between the blocking member 330b and the dividing member 310, and may be attenuated in the first space S1b.
[0070] In traditional display devices, to reduce sound interference between the two channel zones in which the display device vibrates, an additional neutral zone where the display device does not vibrate can be provided between the two channel zones. In this case, since the area in which the display device vibrates to output sound may be reduced, the sound quality of the display device, including sound pressure level, may be degraded.
[0071] The display device 10 in the embodiment may include a blocking member 330 spaced apart from each of the dividing member 310 and the supporting member 320. Therefore, the propagation of a first sound wave generated in the first region A1 to the second region A2 and the propagation of a second sound wave generated in the second region A2 to the first region A1 can be prevented or reduced. Thus, the display device 10 can prevent or reduce sound interference or distortion between channels. Furthermore, since the area in which the display panel 100 vibrates can be widened, the sound quality of the display device 10, including sound pressure level, can be improved. Additionally, since at least some of the first and second sound waves can attenuate and disappear in the first spaces S1a and S1b through the first openings OP1a and OP1b, the display device 10 can prevent or reduce sound pressure level reduction caused by reflected waves or standing waves.
[0072] Figure 8 and Figure 9 This is an example Figure 1 A graph showing the sound output characteristics of the display device. Figure 8 In this diagram, the x-axis represents frequency in Hertz (Hz), and the y-axis represents sound pressure level in decibels (dB). Figure 9 In the diagram, the x-axis represents the frequency in Hz, and the y-axis represents the total harmonic distortion ("THD") ratio as a percentage (%).
[0073] exist Figure 8 and Figure 9 In the diagram, dashed lines illustrate the sound output characteristics of a conventional display device, which provides a neutral region in which the display panel does not vibrate, while solid lines illustrate the sound output characteristics of an embodiment of display device 10. See also Figure 8 and Figure 9Compared with conventional display devices, the display device 10 in the embodiment can reduce the formation of THD and deep frequencies caused by sound interference between channels, reflected waves or standing waves.
[0074] Figure 10 This is an example Figure 1 A plan view of another embodiment of the display device.
[0075] See Figure 10 For example, the blocking member 331 may include a plurality of blocking patterns spaced apart from each other in the first direction DR1. Thus, at least one second opening OP2 may be defined between two adjacent blocking patterns.
[0076] At least a portion of the first sound wave generated by the first sound generator 210 in the first zone A1 can advance to the second opening OP2a. A portion of the first sound wave advancing to the second opening OP2a can diffract as it passes through the second opening OP2a. A portion of the diffracted first sound wave can attenuate in the first space S1a between the blocking member 331a and the dividing member 310.
[0077] At least a portion of the second sound wave generated by the second sound generator 220 in the second zone A2 can advance to the second opening OP2b. A portion of the second sound wave advancing to the second opening OP2b can diffract as it passes through the second opening OP2b. A portion of the diffracted second sound wave can be attenuated in the first space S1b between the blocking member 331b and the dividing member 310.
[0078] Figure 11 This is an example Figure 1 A plan view of another embodiment of the display device.
[0079] See Figure 11 For example, at least a portion of the blocking member 332 may be inclined relative to the dividing member 310. In one embodiment, each of the blocking members 332a and 332b may, for example, include a plurality of blocking patterns inclined relative to the dividing member 310. The ends of each of the blocking patterns may contact each other. In one embodiment, each of the blocking patterns may be inclined relative to the dividing member 310 such that the end of each of the blocking patterns faces, for example, a corresponding one of the first sound generator 210 and the second sound generator 220.
[0080] At least a portion of the first sound wave advancing toward the blocking member 332a can be reflected by the blocking member 332a, and at least a portion of the second sound wave advancing toward the blocking member 332b can be reflected by the blocking member 332b. Since at least a portion of each of the blocking members 332a and 332b can be tilted relative to the dividing member 310, at least a portion of each of the reflected first and second sound waves can change their direction of travel. Therefore, the display device 10 can prevent or reduce the sound pressure reduction caused by reflected waves or standing waves.
[0081] Figure 12 This is an example Figure 1 A plan view of another embodiment of the display device.
[0082] See Figure 12 For example, the display device 10 may further include at least one auxiliary blocking member 340. In one embodiment, for example, the auxiliary blocking member 340a may be disposed in a first region A1 facing the blocking member 330a, and the auxiliary blocking member 340b may be disposed in a second region A2 facing the blocking member 330b. In one embodiment, for example, the auxiliary blocking member 340a may be symmetrical with respect to the blocking member 330a relative to the first sound generator 210, and the auxiliary blocking member 340b may be symmetrical with respect to the blocking member 330b relative to the second sound generator 220.
[0083] Each of the auxiliary blocking members 340a and 340b may be configured to be closer to the support member 320 than each of the first sound generator 210 and the second sound generator 220. In one embodiment, for example, the distance between the auxiliary blocking member 340a and the first short side 323 of the support member 320 in the second direction DR2 may be less than the distance between the auxiliary blocking member 340a and the first sound generator 210. The distance between the auxiliary blocking member 340b and the second short side 324 of the support member 320 in the second direction DR2 may be less than the distance between the auxiliary blocking member 340b and the second sound generator 220.
[0084] In one embodiment, such as Figure 12 As shown, each of the auxiliary blocking members 340a and 340b may extend in the first direction DR1 and may be spaced apart from the support member 320, for example. That is, the auxiliary blocking member 340a may be parallel to the first short side 323 of the support member 320 and may be spaced apart from the first short side 323 by a predetermined distance. The auxiliary blocking member 340b may be parallel to the second short side 324 of the support member 320 and may be spaced apart from the second short side 324 by a predetermined distance. Therefore, second spaces S2a and S2b may be defined respectively between the auxiliary blocking member 340a and the first short side 323 of the support member 320 and between the auxiliary blocking member 340b and the second short side 324 of the support member 320.
[0085] In one embodiment, each of the auxiliary blocking members 340a and 340b may extend in the first direction DR1 and may be spaced apart from, for example, the first long side 321 and the second long side 322 of the support member 320. The length of the auxiliary blocking member 340a in the first direction DR1 may be less than the length of the first short side 323 in the first direction DR1, and the length of the auxiliary blocking member 340b in the first direction DR1 may be less than the length of the second short side 324 in the first direction DR1.
[0086] In one embodiment, for example, a third opening OP3a may be defined between the first long side 321 and the end of the auxiliary blocking member 340a adjacent to the first long side 321, and between the second long side 322 and the other end of the auxiliary blocking member 340a adjacent to the second long side 322. A third opening OP3b may be defined between the first long side 321 and the end of the auxiliary blocking member 340b adjacent to the first long side 321, and between the second long side 322 and the other end of the auxiliary blocking member 340b adjacent to the second long side 322.
[0087] At least a portion of the first sound wave generated by the first sound generator 210 in the first zone A1 can advance to the auxiliary blocking member 340a or the third opening OP3a. The portion of the first sound wave advancing to the auxiliary blocking member 340a is attenuated as it passes through the auxiliary blocking member 340a. A portion of the first sound wave advancing to the third opening OP3a can be incident through the third opening OP3a into the second space S2a between the auxiliary blocking member 340a and the first short side 323 of the support member 320, and can be attenuated in the second space S2a. At least a portion of the second sound wave generated by the second sound generator 220 in the second zone A2 can advance to the auxiliary blocking member 340b or the third opening OP3b. The portion of the second sound wave advancing to the auxiliary blocking member 340b is attenuated as it passes through the auxiliary blocking member 340b. A portion of the second sound wave advancing to the third opening OP3b can be incident through the third opening OP3b into the second space S2b between the auxiliary blocking member 340b and the second short side 324 of the support member 320, and can be attenuated in the second space S2b. Therefore, the display device 10 can prevent or reduce the sound pressure reduction caused by reflected waves or standing waves.
[0088] In one embodiment, each of the auxiliary blocking members 340a and 340b may, for example, comprise a material substantially the same as that of the dividing member 310. In one embodiment, each of the auxiliary blocking members 340a and 340b may, for example, comprise polyurethane, polyolefin, silicone, rubber, aerogel, etc. Additionally, each of the auxiliary blocking members 340a and 340b may comprise single-sided tape, double-sided tape, acrylic adhesive, silicone adhesive, etc.
