Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout.
Hereinafter, exemplary embodiments will be described in detail with reference to the following drawings.
Although the exemplary embodiments are illustrated in terms of a curved display device, the exemplary embodiments may also be applied to a flat display device.
Further, the display device according to an exemplary embodiment may be a device such as a television, a monitor, an electronic whiteboard, an electronic sign (electronic sign), or a flat panel to which the light receiving display panel is applied.
Fig. 1 is a perspective view illustrating a display apparatus according to an exemplary embodiment, fig. 2A and 2B are exploded perspective views illustrating a display module and a display apparatus according to an exemplary embodiment, and fig. 2C is a longitudinal sectional view illustrating a portion of a display module according to an exemplary embodiment.
As shown in fig. 1, a display device 1 according to an exemplary embodiment is formed to have a curvature and a curved shape in which both side ends thereof protrude in a forward direction compared to a central portion thereof. The curved display device may be implemented with a display panel itself having a curvature, or with a flat display panel and a chassis 80 having a curvature and supporting the flat display panel. Therefore, the curved display device can improve the degree of immersion at the time of image display.
Although the exemplary embodiment is described using the curved display device 1, the exemplary embodiment may also be applied to a flat display device, for example, or to a flexible display device in which a curved state and a flat state are interchangeable.
In addition, the exemplary embodiment may also be applied to all display devices 1 to which the light guide plate 40 and the Quantum Dot (QD) sheet 50 are applied regardless of the size of the screen. For example, the exemplary embodiments may be applied to products such as smart televisions, monitors (which may be mounted on a desktop, a wall, a ceiling), or also portable devices such as tablets, notebooks, smart phones, and electronic books.
Such a display device 1 includes: a display module 10 including the QD sheet 50 and displaying an image; at least one circuit board electrically connected to the display module 10; and a housing 12 supporting the display module 10.
The at least one circuit board may include: a power supply board in which a circuit part configured to supply power to the display module is provided; a signal processing board in which a circuit part configured to be connected to an external device or to receive and process an external signal is provided; and a driving board for driving the display module, and the boards may be provided independently or combined and provided.
The display module 10 may include a display panel 20 displaying an image, a backlight unit, and a chassis. The backlight unit may include an optical member such as a light source, a light guide plate, a sheet member, and the like.
That is, according to an exemplary embodiment, the display module, which is a side-in type backlight unit, may include a light source 30 provided at the rear of the display panel 20 and a light guide plate 40 provided to guide light emitted by the light source 30 to the display panel 20. The Light Guide Plate (LGP) may be used to convert light emitted from the light source 30 into a surface light source and emit the light toward the display panel 20.
The backlight unit may further include a sheet member. The sheet member may include an optical sheet 60 having optical characteristics and a QD sheet 50 provided to improve color reproducibility.
The rack 80 may include a top rack 82 and a bottom rack 84 provided at the rear of the top rack 82. The top chassis 82 and the bottom chassis 84 may also be coupled by an insert coupling or a screw coupling. A chassis 80 may be provided to support the display panel 20.
In an exemplary embodiment, since the curved display device 1 is formed in a curved shape, the display module 10 embedded in the curved display device 1 is also formed to have a longitudinal curvature. Accordingly, the display panel 20, the light guide plate 40, the middle mold 70, the top chassis 82, and the bottom chassis 84 forming the display module 10 are formed to have a longitudinal curvature and have a shape in which both side ends thereof protrude in a forward direction compared to a middle portion thereof. Here, the respective members may have the same curvature, but the respective members may also be designed to have different curvatures according to the design.
For example, at least one of the display panel 20, the light guide plate 40, and the sheet member may be formed in a planar shape, and the curvature may also be maintained by the chassis 82 and 84.
The light source 30 may be provided at least a portion of the periphery of the light guide plate 40, and may emit light. The light source 30 may be provided along a short side of the light guide plate 40, or may also be provided along a long side thereof. The position of the light source 30 is not limited as long as the light source 30 is provided along at least a portion of the circumference of the light guide plate 40 and is provided to emit light to the light guide plate 40. Further, the light source 30 may be provided at least one side in the chassis 80. For example, the light source 30 may be provided on one side of the display module 10 as shown in fig. 2A, or a pair of light sources 30 may be provided on both sides of the display module 10 as shown in fig. 2B.
The display module 10 may include an intermediate mold 70. The intermediate mold 70 and the frame may be provided to seat at least portions of the components within the frame.
The display panel 20 and the top chassis 82 may be provided in front of the middle mold 70, and the bottom chassis 84 may be provided behind it and may support components. In addition, the middle mold 70 may maintain a state in which the display panel 20 and the bottom chassis 84 are spaced apart from each other, and may minimize heat conduction from heat generated from the light source or the like to the display panel through the bottom chassis.
The top chassis 82 includes: a bezel portion 82a covering a front edge of the display panel 20; and a top side surface portion 82b bent from an end of the frame portion 82a in a backward direction and covering a side surface of the intermediate mold 70.
The bottom chassis 84 includes: a rear surface portion 84a forming a rear surface of the display module 10; and a bottom side surface portion 84b extending from the periphery of the rear surface portion 84a in the forward direction and coupled to the inside of the middle mold 70.
Since the bottom chassis 84 is formed to have both side ends protruding in a curved shape with respect to the middle portion thereof, the rear surface portion 84a of the bottom chassis 84 is also formed to have both side ends protruding in a curved shape with respect to the middle portion thereof in the forward direction.
Therefore, the light generated by the light emitting diodes is reflected by the reflection part 45 provided at the rear surface part 84a of the bottom chassis 84 formed as a curved surface and is guided to the display panel 20. That is, the reflection portion 45 serves to guide light emitted by the light emitting diode to the display panel 20.

The light source 30 includes a Light Emitting Diode (LED)30 a. A plurality of LEDs may be provided at equal intervals and may be provided to form one module. Each of the modules may be provided at an edge portion of the light guide plate 40. The LEDs include blue LEDs. The light source 30 may also include a circuit board 30b, and the circuit board 30b may be provided to send electrical signals to the LED30a and turn the LED30a on/off. As an exemplary embodiment, the LEDs 30a are provided in a line and operate on a circuit board 30 b. The light sources 30 are provided at both sides of the space between the light guide plate 40 and the inner surface of the bottom chassis 84, that is, the side of the side surface portion 84b of the bottom chassis 84. Accordingly, the light generated by the light source 30 is emitted to the rear surface portion of the bottom chassis 84 through the space between the rear surface portion of the bottom chassis 84 and the light guide plate 40.
The light guide plate 40 may include a reflective portion 45 at a rear surface thereof. Specifically, the light guide plate 40 may include a light guide portion 40a and a reflection portion 45. The reflective portion 45 may be provided at the rear surface of the light guide plate 40 such that light generated by the light source faces a forward direction. Specifically, the reflection part 45 may be provided such that light generated by the light source is reflected toward the display panel 20.
The reflection part 45 may be provided in the shape of a reflection plate, or may also be provided in the shape of a reflection sheet. Further, the reflection part 45 may be separately provided to the light guide plate 40 and provided at the rear surface of the light guide plate 40, or may be integrally formed with the light guide plate 40. Further, since the rear surface of the light guide plate 40 is reflectively coated, the same effect as that described above can be obtained.
The light guide plate 40 is provided to transmit light generated by the light source therethrough. For this, the light guide plate 40 may be formed of a transparent resin. The light guide plate 40 may be provided separately from the light source at a predetermined interval to minimize deformation due to heat generated by the light source.
The display device 1 may include a sheet member.
The sheet member may include an optical sheet 60 having optical characteristics and a QD sheet 50 provided to improve color reproducibility.
The optical sheet 60 may include a diffusion sheet 61 that diffuses incident light and a Dual Brightness Enhancement Film (DBEF) sheet 62 as a high brightness prism sheet. The optical sheet 60 may include a polarizing plate and a prism sheet.
The optical sheet 60 is interposed between the light guide plate 40 and the display panel, and changes optical characteristics of light emitted from the light guide plate 40.
The QD sheet 50 is provided for color reproducibility. The color reproduction coefficient is a criterion of how close the color is to the natural color and how large an area can be marked on the color coordinates. Since the QD sheet 50 has a higher color purity of white light compared to the conventional art, which converts white light emitted from an LED using a color filter, the efficiency of light passing through the color filter becomes high, and the power efficiency of the entire display is improved. The QD sheet 50 may also be referred to as a quantum dot sheet.
QDs will now be described. Generally, an electron present in the valence band jumps to the conduction band when the electron absorbs energy. The electrons then lose energy and return to the valence band, at which point the absorbed energy is radiated as light. QDs produce strong fluorescence in a narrow band. Visible light of all kinds of colors can be generated according to the size of the QDs. In addition, since QDs generate natural colors by themselves, there is no color loss, and thus QDs are also materials with high color reproducibility. When the particles of the QDs are small, light having a shorter wavelength is generated, and when the particles are large, light having a longer wavelength is generated. The QDs may be compounds such as cadmium selenide (CdSe), cadmium sulfide (CdS), cadmium telluride (CdTe), zinc selenide (ZnSe), zinc telluride (ZnTe), zinc sulfide (ZnS), and the like.
The QD sheet 50 may be provided such that light passing through the light guide plate 40 is emitted through the QD sheet 50. The QD sheet 50 may be attached to the light guide plate 40 at the front surface of the light guide plate 40. The QD sheet 50 is attached to the front surface of the light guide plate 40 such that light emitted from the light guide plate 40 passes therethrough.
Since the light of the LED reaches the QD sheet 50 through the light guide plate 40, the QD sheet 50 is less affected by the heat of the LED, and thus it is more reliable.
The QD sheet 50 may include a yellow QD sheet 50 corresponding to a blue LED. The blue light emitted by the blue LED is converted into white light while passing through the yellow QD sheet 50.
As described above, the light guide plate 40 according to the exemplary embodiment may include the light guide portion 40a and the reflection portion 45. Here, the reflection portion 45 may also be formed as a separate sheet.
The light guide portion 40a may include a light guide plate body 41 and a light guide plate groove portion 43, and the light guide plate groove portion 43 is formed on the light guide plate body 41 in a groove shape to be supported by the first guide portion 110 in the groove shape. The light guide plate body 41 may include a light guide plate seating portion 42 formed to protrude from the same surface of the light guide plate body 41. The light guide plate groove part 43 may be formed at the light guide plate seating part 42.
The display device 1 may include a guide member 100.
The guide member 100 is provided to align the installation positions of the light guide plate 40 and the QD sheet 50 within the chassis 80. In order to emit white light through the QD sheet 50, the light emitted from the light guide plate 40 passes through the QD sheet 50. For this, the guide member 100 is provided to simultaneously guide and align the light guide plate 40 and the QD sheet 50 and stably maintain an attachment force therebetween.
The guide member 100 may be fixed within the frame 80. Specifically, the guide member 100 may be fixed to the bottom chassis 84. At least one guide member 100 is provided to guide or position components within the housing 80.
The shape of the guide member 100 is not limited, but may have a cross-section perpendicular to the width direction of a rectangular shape to prevent the position misalignment of the light guide plate 40 and the QD sheet 50. In addition, the light guide plate groove portion 43 of the light guide plate 40 and the QD sheet groove portion 53 formed at the edge of the QD sheet 50 may also be provided to correspond to the guide member 100. The cross section perpendicular to the width direction of the guide member 100 is not limited to a rectangular shape, may be provided by rounding the vertices of the rectangular shape, and may also be formed in a polygonal shape. Further, a cross section perpendicular to the width direction of the guide member 100 may also be provided in a circular or elliptical shape.
The guide member 100 may include a guide portion configured to properly position components within the housing 80. The guide portions 110 and 120 may guide or position components within the frame 80.
The guide portion may include a first guide portion 110 and a second guide portion 120.
As an exemplary embodiment, a configuration in which the first guide portion 110 and the second guide portion 120 are integrally formed is described, but the first guide portion 110 and the second guide portion 120 may also be separately formed, and the light guide plate and the QD sheet may also be guided at different positions therefrom.
The first guide portion 110 is coupled to and guides the light guide plate groove portion 43 of the light guide plate 40, and the second guide portion 120 is coupled to and guides the QD sheet groove portion 53 of the QD sheet 50.
The first guide portion 110 is formed by the bottom chassis 84 in a longitudinal direction, which is a width direction of the bottom chassis 84, such that one side of the light guide plate 40 is positioned. The width direction may be defined as a direction perpendicular to the bottom chassis 84. Further, since the top chassis 82 and the bottom chassis 84 are coupled as the front chassis and the rear chassis of the display module 10, respectively, the width direction may refer to a direction from the top chassis 82 to the bottom chassis 84. The first guide portion 110 may include a first position guide portion 112 and a first seating portion 114.
The first position guide part 112 is provided to guide the position of the light guide plate 40. At least one guide member 100 is provided at the chassis 80 and guides the light guide plate 40 and the QD sheet 50 at the same time. That is, when the light guide plate 40 is mounted at the bottom chassis 84, the first position guide portion 112 of the guide member 100 is provided to guide the light guide plate 40 to its mounting position, and the second guide portion 120 is provided to guide the QD sheet 50 to its mounting position.
Since the light guide plate groove part 43 corresponding to the first guide part 110 is formed at the light guide plate seating part 42 protruding from the edge of the light guide plate body 41, the movement of light in the light guide plate body 41 may not be disturbed.
In addition, the light guide plate groove part 43 may also be formed in a groove shape at the edge of the light guide plate body 41.
Further, since the light guide plate 40 is formed in a substantially rectangular parallelepiped shape, the light guide plate 40 may distinguish a long side from a short side, and since the display device is vertically mounted, the light guide plate 40 may be downwardly offset due to gravity, and thus the light guide plate 40 may be guided by the guide members 100 formed at the long sides thereof and mounted at the chassis 80.
Further, the light guide plate groove part 43 may be formed at a position where no light source is provided, so that the light path of the light source disposed at the edge of the light guide plate 40 is not disturbed. That is, in the exemplary embodiment, the light source is provided at the edge of the short side of the light guide plate 40, and the guide member 100 is formed at two positions of the upper portion and one position of the lower portion of the long side of the light guide plate 40. Accordingly, since the three positions of the light guide plate 40 are guided, the positions of the light guide plate 40 are aligned. In the exemplary embodiment, three guide members 100 are applied thereto, but the number of the guide members 100 is not limited.
The first seating portion 114 is provided to seat the light guide plate 40 guided by the first position guide portion 112. The first seating portion 114 may be separately formed to extend from the first position guide portion 112, and may also be formed on a surface of the first position guide portion 112. When the first seating portion 114 is separately formed to extend from the first position guide portion 112, the cross-sectional area of the first seating portion 114 is greater than that of the first position guide portion 112 in the first guide portion 110.
In an exemplary embodiment, the first guide portion 110 is formed in a rectangular shape in cross section, and the cross-sectional area thereof may be gradually increased. In such a configuration, the light guide plate groove portion 43 of the light guide plate 40, which will be described later, is seated on the first seating portion 114 by the first position guide portion 112.
Although the shape of the first seating portion 114 is not limited, in an exemplary embodiment, the first seating portion 114 may include a first seating surface 117 having a flat surface and a cross-sectional area that increases toward the bottom chassis 84. The first seating surface 117 may be formed to have a cross-sectional area that gradually increases from the first seating portion 114 toward the bottom chassis 84. Further, the first seat portion 114 may include a first seat curved surface 115 having a cross-sectional area that gradually increases toward the bottom housing 84. In addition, the first seating portion 114 may include a first supporting surface 116, and the first supporting surface 116 is formed perpendicular to the flat surface of the first position guide portion 112 such that one surface of the light guide plate 40 is seated thereon.
The first seating portion 114 may be provided to include at least one of a first seating curved surface 115, a first seating surface 117, and a first support surface 116. Although the light guide plate 40 is shown to be seated on the first seating surface 117, the light guide plate 40 may be seated on the first seating curved surface 115 or the first support surface 116.
The seating position of the light guide plate 40 seated on the guide member 100 is guided by the first position guide portion 112, and the light guide plate 40 is seated on the first seating portion 114. Specifically, the seating position of the light guide plate groove portion 43 is guided by the first position guide portion 112, and the light guide plate groove portion 43 is seated on the first seating portion 114.
The second guide portion 120 may be formed to extend from the first guide portion 110. The second guide part 120 may be provided to support the QD sheet 50.
The second guide portion 120 is formed by the bottom chassis 84 in the longitudinal direction, which is the width direction of the bottom chassis 84, so that one side of the QD sheet 50 is seated. The width direction may be defined as a direction perpendicular to the bottom chassis 84. Further, since the bottom chassis 84 is provided behind the top chassis 82, the width direction may also be defined as a direction from the top chassis 82 to the bottom chassis 84 due to it.
The second guide portion 120 may include a second position guide portion 122 and a second seat portion 124.
The second position guide portion 122 is provided to guide the support position of the QD sheet 50. At least one guide member 100 is provided and guides and supports the light guide plate 40 and the QD sheet 50. The second position guide portion 122 of the guide member 100 is provided to guide the QD sheet 50 to its mounting position when the QD sheet 50 is mounted at the bottom chassis 84.
The QD sheet 50 may include a QD sheet body 51 and a QD sheet groove portion 53, and the QD sheet groove portion 53 is formed at the QD sheet body 51 in a groove shape to be supported by the second guide portion 120 in a groove shape. The QD sheet body 51 may include a QD sheet holder portion 52 formed to protrude from the same surface of the QD sheet body 51. Since the QD sheet groove portion 53 is formed in the QD sheet seating portion 52, the movement of light in the QD sheet body 51 may not be interfered by the second guide portion 120 provided at the QD sheet groove portion 53. The QD sheet groove portion 53 may be formed in the QD sheet holder portion 52, or may also be formed in the QD sheet body 51.
The guide member 100 according to the exemplary embodiment is formed at two positions of the upper portion and one position of the lower portion of the QD sheet 50, and thus the guide member 100 guides three positions of the QD sheet 50 and determines the position of the QD sheet 50.
The second seat portion 124 is provided to seat the QD sheet 50 guided by the second position guide portion 122. The second seating portion 124 may be formed on a surface of the second position guide portion 122, or may be formed separately from the second position guide portion 122.
The second seating portion 124 may also include a second supporting surface 126 formed in a flat surface perpendicular to the second position guide portion 122 and a second seating surface 127 formed at a surface of the second position guide portion 122 such that one surface of the QD sheet 50 is seated. However, the shape of the second seating portion 124 is not limited thereto, and the second seating portion 124 may be formed to include at least one of a second seating curved surface, a second seating surface 127, and a second support surface 126, as shown with respect to the first seating portion 114. The shape of the second seat curved surface, not depicted, is the same as the shape of the first seat curved surface 115. In the exemplary embodiment, a second seating surface 127 and a second support surface 126 are applied and shown.
The seating position of the QD sheet 50 seated by the guide member 100 is guided by the second position guide portion 122, and the QD sheet 50 is seated on the second seating portion 124. Specifically, the seating position of the QD sheet groove portion 53 is guided by the second position guide portion 122, and the QD sheet groove portion 53 seats on the second seat portion 124.
The second guide portion 120 may be formed to form a step with respect to the first guide portion 110. Specifically, the cross-sectional area perpendicular to the longitudinal direction of the second position guide portion 122 may be smaller than the cross-sectional area perpendicular to the longitudinal direction of the first position guide portion 112. Further, when the light guide plate 40 is mounted at the first guide portion 110, the first guide portion 110 may be provided not to protrude higher than the light guide plate 40. That is, the height of the first guide portion 110 may be provided to correspond to the thickness of the light guide plate 40.
As described above, since the first and second guide portions 110 and 120 may be formed to be stepped from each other and the first guide portion 110 is formed not to protrude higher than the light guide plate 40, the light guide plate 40 mounted at the first guide portion 110 and the QD sheet 50 mounted at the second guide portion 120 are formed to maintain the attachment force of each other and are independently mounted at the guide member 100. Accordingly, when the light guide plate 40 is mounted at the first guide portion 110 and the QD sheet 50 is mounted at the second guide portion 120, no space is left between the light guide plate 40 and the QD sheet 50, and the light guide plate 40 and the QD sheet 50 are attached to each other.
Since the second position guide portion 122 of the second guide portion 120 is formed to form a step along the circumference thereof in all directions with respect to the first position guide portion 112 of the first guide portion 110, the portion of the QD sheet 50 mounted at the guide member 100 may be formed to be relatively wider than the portion of the light guide plate 40 mounted at the guide member 100. Accordingly, the light passing through the light guide plate 40 may stably pass through the QD sheet 50 even at a portion adjacent to the guide member 100.
The guide member 100 may include a member fixing portion 130.
The member fixing portion 130 is formed to fix the guide member 100 to the bottom chassis 84. The member fixing portion 130 is formed to extend from the first guide portion 110 and fixed to the bottom chassis 84. Specifically, a coupling groove may be formed at the member fixing portion 130, and the coupling groove and the bottom chassis 84 may be coupled by screw coupling through the fixing member 131. However, the coupling method of the member fixing portion 130 is not limited thereto.
The member fixing part 130 may be provided at a lower portion of the light guide plate 40. That is, the member fixing portion 130 fixing the guide member 100 to the bottom chassis 84 may be provided between the light guide plate 40 and the bottom chassis 84. Specifically, when the longitudinal direction of the guide portion refers to the support shaft 100a, and when the direction in which the member fixing portion 130 is spaced apart from the support shaft 100a and fixed to the bottom chassis 84 is referred to as the coupling shaft 130a, the coupling shaft 130a may be provided to pass through the inside of the light guide plate 40 or the QD sheet 50 instead of the support shaft 100 a.
With such a configuration, the display apparatus 1 may be prevented from being widened due to the guide member 100, the guide member 100 supporting the light guide plate 40 and the QD sheet 50. That is, space efficiency may be improved by the guide member 100.
Further, when the equipment is worn out, or when the coupling is not completely or loosely performed at the member fixing part 130, the guide member 100 is rocked around the coupling shaft 130a with respect to the bottom chassis 84. However, since the member fixing portion 130 is interposed between the light guide plate 40 and the bottom chassis 84, the guide member 100 may not be spaced apart from the light guide plate 40 and the QD sheet 50 even in such a case.
Further, since the member fixing portion 130 is interposed between the light guide plate 40 and the bottom chassis 84, a portion to which the guide member 100 is fixed may be covered.
The guide member 100 may include a position decision part 140 that decides a mounting position of the guide member 100.
The position decision part 140 may be formed to extend from the first guide part 110. The position decision part 140 is formed to protrude from the first guide part 110 and is coupled to the bottom chassis 84. Specifically, the position determining part 140 is inserted into the position determining groove 142 of the rear surface of the bottom chassis 84. That is, the coupling position of the guide member 100 on the bottom chassis 84 is guided by the position decision portion 140, and the guide member 100 is fixed to the bottom chassis 84 by the member fixing portion 130. When the position decision part 140 fixes the guide member 100 to the bottom chassis 84, the position decision part 140 performs a temporary fixing function, and when the coupling is completely achieved, the position decision part 140 performs a function of assisting the fixing so that the guide member 100 is firmly fixed to the bottom chassis 84.
Although the position of the position decision part 140 is not limited, the position decision part 140 is spaced apart from the coupling shaft 130a of the member fixing part 130. Since the portion of the guide member 100 temporarily fixed to the bottom chassis 84 by the position decision part 140 and the coupling shaft 130a are spaced apart from each other, the guide member 100 can be more firmly fixed to the bottom chassis 84. That is, the guide member 100 is coupled to the bottom chassis 84 by the member fixing portion 130, and even when the member fixing portion 130 is loosened, the positions of the guide member 100 and the member fixing portion 130 are supported by the position decision portion 140 provided separately from the member fixing portion 130.
Although the method of manufacturing the guide member 100 is not limited, the guide member 100 may be integrally formed using an injection molding method. Further, the guide member 100 may be formed of plastic. However, the material of the guide member 100 is not limited thereto, and an elastic material may also be applied thereto. For example, the guide member 100 may be formed of rubber.
In addition, when heat is generated inside the display module 10 due to the light source 30, the light guide plate 40 or the QD sheet 50 may expand. Here, the light guide plate 40 and the QD sheet 50 are mainly supported by the guide member 100, so that the positions of the light guide plate 40 and the QD sheet 50 are not misaligned.
Further, the guide member 100 may be formed in black to prevent light emitted by the plurality of light sources from being reflected by the guide member 100.
The display device 1 may comprise an intermediate mould 70.
In an exemplary embodiment, since the intermediate mold 70 is coupled to and provided at the bottom chassis 84 at the edge of the front of the light guide plate 40, the intermediate mold 70 may be provided to fix the light guide plate 40 and the QD sheet 50 and support the optical sheet 60 and/or the display panel 20.
The intermediate die 70 includes an intermediate body 72 and an extrusion rib 74.
The intermediate body 72 is coupled to the bottom frame 84. The intermediate body 72 is formed to be coupled along a peripheral surface of the bottom chassis 84.
Specifically, the intermediate body 72 includes a first body coupling portion 72a coupled to the inside of the side surface portion 84b of the bottom chassis 84 and a second body coupling portion 72b coupled to the outside of the side surface portion 84b of the bottom chassis 84. With this configuration, the intermediate die 70 is coupled to the bottom chassis 84 such that the side surface portion 84b of the bottom chassis 84 is disposed between the first body coupling portion 72a and the second body coupling portion 72 b.
The pressing rib 74 is formed to extend from the middle body 72 and is provided to have an end portion disposed at the front of the light guide plate 40 and the QD sheet 50. When the intermediate mold 70 is coupled to the bottom chassis 84, the pressing rib 74 is provided to press the QD sheet 50 and the light guide plate 40 together toward the bottom chassis 84. Accordingly, the QD sheet 50 and the light guide plate 40 may be attached to each other. In addition, the light guide plate 40 and the QD sheet 50 seated on the guide member 100 are fixed to each other.
The pressing rib 74 may be formed along at least a portion of the peripheries of the QD sheet 50 and the light guide plate 40. Since the middle mold 70 may be formed along the circumference of the bottom chassis 84, the pressing rib 74 may be formed along the entire circumference of the QD sheet 50 and the light guide plate 40.
Further, since the pressing rib 74 is formed to extend from the middle body 72 and have an end reaching the front surface of the QD sheet 50, the pressing rib 74 may not expose the guide member 100 to the outside. That is, the guide member 100 may be covered by the pressing rib 74, and the guide member 100 may not be affected by the outside.
Hereinafter, an assembling method of the display apparatus 1 according to an exemplary embodiment will be described.
Fig. 8 to 10 are views illustrating an assembly process of a display apparatus according to an exemplary embodiment.
The guide member 100 is temporarily fixed to the bottom chassis 84 using the position determining part 140 of the guide member 100. After the guide member 100 is temporarily fixed to the bottom chassis 84, the member fixing portion 130 and the bottom chassis 84 are coupled by the screw, and the guide member 100 is fixed to the bottom chassis 84.
After the guide member 100 is coupled to the bottom chassis 84, the light guide plate 40 is seated on the first guide portion 110. Specifically, the light guide plate groove part 43 is guided along the first position guide part 112 of the first guide part 110 and seated on the first seating part 114.
After the light guide plate 40 is seated on the first guide part 110, the QD sheet 50 is seated on the second guide part 120. Specifically, the QD sheet groove portion 53 is guided along the second position guide portion 122 of the second guide portion 120 and seated on the second seat portion 124.
In an exemplary embodiment, the guide member 100 is provided at two positions corresponding to the upper portions of the light guide plate 40 and the QD sheet 50 and one position corresponding to the lower portions of the light guide plate 40 and the QD sheet 50, and the guide member 100 positions the light guide plate 40 and the QD sheet 50.
The position and number of the guide members 100 are not limited to the above description. For example, the guide members 100 may be provided at one position and two positions of the lower part of the light guide plate 40 and the QD sheet 50 at the upper part, and may be provided at the position where the light source is provided, and a plurality of guide members 100 may also be provided along the periphery of the light guide plate 40 and the QD sheet 50.
When the light guide plate 40 and the QD sheet 50 are seated on the guide member 100, the middle mold 70 is coupled to the bottom chassis 84. When the intermediate body 72 is coupled to the bottom chassis 84, the pressing ribs 74 press the light guide plate 40 and the QD sheet 50 toward the bottom chassis 84 (i.e., in a rearward direction).
Accordingly, both the light guide plate 40 and the QD sheet 50 may be seated using the guide member 100, and both the light guide plate 40 and the QD sheet 50 are pressed together by the pressing rib 74.
Hereinafter, a display apparatus according to another exemplary embodiment will be described.
In the following description of the exemplary embodiments, a description of the repetitive configuration will be omitted.
Fig. 11 is a view illustrating coupling of a guide member and a chassis of a display apparatus according to another exemplary embodiment, and fig. 12 is a perspective view illustrating a guide member and a configuration adjacent thereto of a display apparatus according to another exemplary embodiment.
The display device 1 may include a guide member 200. The guide member 200 is provided to fix the light guide plate 40 and the QD sheet 50. In order to improve color reproducibility using the QD sheet 50, light emitted through the light guide plate 40 passes through the QD sheet 50. For this, the guide member 200 is provided to fix the light guide plate 40 and the QD sheet 50.
The guide member 200 may be fixed to the inside of the frame 80. Specifically, the guide member 200 may be fixed to the bottom chassis 84. At least one guide member 200 is provided to secure or position components within the housing 80.
The guide member 200 may include a guide portion provided to secure or seat a component within the housing 80.
The first guide portion 210 is provided to support the light guide plate 40, and the second guide portion 220 is provided to support the QD sheet 50.
The first guide portion 210 is formed in a longitudinal direction, which is a direction from the side surface portion 84b of the bottom chassis 84 toward the inside of the bottom chassis 84, such that one side of the light guide plate 40 is positioned. Since the first guide portion 210 is formed in a direction from the side surface portion 84b of the bottom chassis 84 toward the inside of the bottom chassis 84, the first guide portion 210 may be provided to support a side surface of the light guide plate groove portion 43 of the light guide plate 40.
The shape of the first guide portion 210 is not limited, but in an exemplary embodiment, it may be provided in a cylindrical shape.
The first guide portion 210 may include a first position guide portion 212 and a first seating portion 214.
