Description

Technical Field

[0001] This disclosure relates to a display device. Background Technology

[0002] With the development of the information society, the demand for display devices used to display images to users has increased and diversified. For example, display devices are now used in various consumer electronics devices, such as smartphones, digital cameras, laptops, navigation devices, and smart TVs.

[0003] The display device can be a flat panel display device, such as a liquid crystal display device, a field emission display device, or an organic light-emitting display device. In such a flat panel display device, because each pixel in the display panel includes a self-emitting light element, the light-emitting display device can display images without requiring a backlight unit to provide light to the display panel.

[0004] Recently, the demand for stereoscopic image display devices that provide a three-dimensional effect to displayed images has increased. As an example, a display device can achieve a three-dimensional effect by using a binocular parallax method that utilizes parallax images from both the left and right eyes. Binocular parallax methods are classified into eyeglass methods that require the user to wear glasses to visualize the three-dimensional image and non-eyeglass methods that do not require the user to wear glasses. Furthermore, methods for additionally forming optical components in the display device to provide a three-dimensional effect are being developed. Various other methods for displaying images to provide a three-dimensional effect are under development. Utility Model Content

[0005] The purpose of this utility model is to provide a display device that can display images with a three-dimensional effect using multiple foldable display panels that can be arranged in three dimensions.

[0006] An embodiment of the present disclosure also provides a display device capable of displaying three-dimensional images through an assembly structure of a foldable panel, the assembly structure of which includes a first flat panel having a circular or polygonal shape in a plan view and a second flat panel having an inner hole, the first flat panel being incorporated into the inner hole.

[0007] However, the aspects of the embodiments of this disclosure are not limited to those set forth herein. The above and other aspects of this disclosure will become clearer to those skilled in the art from the following detailed description of embodiments of this disclosure.

[0008] According to an embodiment of this disclosure, a display device includes: a first foldable panel comprising a first flat panel and a second flat panel, the first flat panel having a circular or polygonal shape in a plan view, the second flat panel having a plate shape in a plan view and being configured with the first flat panel in a folding or unfolding structure, wherein the first flat panel can be folded into a first inner hole region defined in the second flat panel; and a second foldable panel comprising a third flat panel and a fourth flat panel, the third flat panel having a circular or polygonal shape in a plan view, the fourth flat panel having a plate shape in a plan view and being configured with the third flat panel in a folding or unfolding structure, wherein the third flat panel can be folded into a second inner hole region defined in the fourth flat panel.

[0009] In one embodiment, one end of the first flat panel display is fixed to a first folding module disposed at one end of the second flat panel display, and the rear surface of the first flat panel display can be folded into the first inner hole region, or can be unfolded from the first inner hole region.

[0010] In an embodiment, the first flat panel display has a circular, triangular, quadrilateral, pentagonal, or hexagonal shape in a plan view.

[0011] In one embodiment, a first flat panel display panel is foldable into a first inner aperture region. When folded into the first inner aperture region, the first flat panel display panel is attached to the second flat panel display panel in a plate shape in a plan view. When the first flat panel display panel is folded into the first inner aperture region, the first image display surface of the first flat panel display panel and the second image display surface of the second flat panel display panel are arranged in the same direction in a plate shape in a plan view. The first flat panel display panel unfolds towards one end of the second flat panel display panel via a first folding module.

[0012] According to embodiments of this disclosure, a display device includes: a first foldable panel comprising a first flat panel and a second flat panel, wherein the first flat panel has a circular, triangular, quadrilateral, pentagonal, or hexagonal shape in a plan view, and the second flat panel has a plate shape in a plan view, wherein the first flat panel is foldable into or unfoldable from a first inner hole region defined in the second flat panel; and a second foldable panel comprising a third flat panel and a fourth flat panel, wherein the third flat panel has a circular, triangular, quadrilateral, pentagonal, or hexagonal shape in a plan view, and the fourth flat panel has a plate shape in a plan view, wherein the third flat panel is foldable into or unfoldable from a second inner hole region defined in the fourth flat panel. The first flat panel and the third flat panel have the same shape as each other. The first inner hole region is formed at the center of the front surface of one end including the second flat panel in a shape corresponding to the outline shape and size of the first flat panel in the plan view.

[0013] Using the display device according to the embodiment, multiple foldable display panels that can be arranged in three dimensions can be used to display images with a three-dimensional effect in a non-glasses state.

[0014] Furthermore, by displaying images with a three-dimensional effect through an assembly structure of foldable display panels, the display efficiency of stereoscopic images can be improved at a low cost, and the utilization rate of the display device can be increased.

[0031] In the following description, non-limiting embodiments will be illustrated with reference to the accompanying drawings.

[0032] Figure 1 This is a perspective view showing a display device according to an embodiment of the present disclosure.

[0033] The display device 10 according to embodiments of the present disclosure can be applied to portable electronic devices, such as tablet PCs, portable multimedia players (PMPs), ultra-mobile PCs (UMPCs), e-books, e-notebooks, mobile phones, smartphones, and mobile communication terminals. Furthermore, the display device 10 according to embodiments can be applied as a display unit in a television, laptop computer, monitor, billboard, or Internet of Things (IoT) device. However, embodiments of the present disclosure are not limited to these, and the display device 10 can be applied to a variety of small, medium, or large electronic devices.

[0034] Reference Figure 1 According to the embodiment, the display device 10 includes a first foldable panel 100 and a second foldable panel 120. The first foldable panel 100 includes a first flat panel display panel DP1 and a second flat panel display panel DP2. The second foldable panel 120 includes a third flat panel display panel DP3 and a fourth flat panel display panel DP4.

[0035] In an embodiment, the first foldable panel 100 includes a first flat panel display panel DP1 and a second flat panel display panel DP2. The first flat panel display panel DP1 has a circular or polygonal shape in a plan view (e.g., in a plane defined in the X-axis and Y-axis directions when in an unfolded state). The second flat panel display panel DP2 is foldably bound to (e.g., fixed to) the first flat panel display panel DP1.

[0036] In an embodiment, the first flat panel DP1 of the first foldable panel 100 can be formed in a circular or polygonal shape in a plan view. Figure 1An embodiment in which the first flat panel display panel DP1 is formed in a plan view as a quadrilateral shape that is trapezoidal. However, the embodiments of this disclosure are not limited to this, and the shape of the first flat panel display panel DP1 in the plan view can be changed. For example, in an embodiment, the first flat panel display panel DP1 may be formed in a circular shape in the plan view, or in a polygonal shape such as a triangle, a quadrilateral shape other than a trapezoid (e.g., a rhombus), a pentagon, or a hexagon.

[0037] In one embodiment, one end of the first flat panel display panel DP1 is assembled (e.g., fixed) to a first folding module disposed at one end of the second flat panel display panel DP2 (e.g., see...). Figure 5 HG1), and the rear surface of the first flat panel display panel DP1 is folded to (e.g., foldable to) the inner hole region defined in the second flat panel display panel DP2 (see HG1). Figure 4 and Figure 5 The second flat panel display panel DP2 may be formed at opposite ends (e.g., in the X-axis direction) and an inner hole region (such as the first inner hole region IHA1) formed by an empty space is disposed between the two surfaces.

[0038] Reference Figure 1 In this embodiment, the first flat panel display panel DP1 can be folded in the Y-axis direction, and the rear surface of the first flat panel display panel DP1 can be coupled to the inner hole area of ​​the second flat panel display panel DP2 (see...). Figure 4 and Figure 5 (IHA1). In an embodiment, the inner hole region of the second flat panel DP2 can be formed as a groove shape with a rear surface closed by a rear surface cover, or as a hole shape with an open rear surface.

[0039] When the first flat panel DP1 and the second flat panel DP2 are folded and joined together, the rear surface of the first flat panel DP1 folds into the inner hole region formed in the second flat panel DP2. Therefore, the first flat panel DP1 and the second flat panel DP2 can be bound (e.g., fixed) to each other in a plate shape in a planar view. Furthermore, in an embodiment, the first image display surface of the first flat panel DP1 and the second image display surface of the second flat panel DP2 can be arranged in the same plate shape in the Z-axis direction in a planar view. Conversely, in an embodiment, the first flat panel DP1 can unfold in the Z-axis direction and in the -Y-axis direction opposite to the Y-axis direction, so that no plate shape is formed in the first foldable panel 100.

[0040] In an embodiment, the second flat panel DP2 of the first foldable panel 100 is formed in a circular or polygonal shape in a plan view, and an inner hole region with a shape corresponding to the outline shape and size (e.g., area) of the first flat panel DP1 in a plan view is formed at the center portion of the front surface including one side surface (e.g., the first side surface) of the second flat panel DP2.

[0041] As an example, in an embodiment, the second flat panel display panel DP2 can be formed in a planar view in a shape such as a rectangle, square, circle, or ellipse. For example, the second flat panel display panel DP2 can be formed in a planar view as a rectangle having a relatively long side formed in the transverse direction, which is the X-axis direction. However, embodiments of this disclosure are not limited to this, and the relatively long side can be positioned in the longitudinal direction, or the second flat panel display panel DP2 can be rotatably mounted such that the relatively long side can be variably positioned in the transverse or longitudinal direction.

[0042] In an embodiment, the second image display surface of the second flat panel DP2 is formed on at least one side surface direction of the inner hole region (e.g., a lateral side surface in the X direction) to surround at least one side surface of the inner hole region.

[0043] Based on the shape of the second flat panel display panel DP2 in the plan view and the shape of the inner hole area corresponding to the first flat panel display panel DP1 in the plan view, a second image display surface having a semi-circular shape, a cylindrical or cylindrical shape, or a polygonal shape (such as a triangular shape or a quadrilateral shape) in the plan view can be formed on the front surface direction of the second flat panel display panel DP2.

[0044] like Figure 1 As shown, in an embodiment where the second flat panel display panel DP2 is formed into a rectangular shape in a plan view and the first flat panel display panel DP1 and its corresponding inner hole region are formed into a trapezoidal shape, a second image display surface having a right-angled triangular shape is formed in the second flat panel display panel DP2. For example, one or both of the right-angled triangular surfaces formed at opposite ends of the second flat panel display panel DP2 (e.g., in the X-axis direction) can be the second image display surface. In an embodiment where the second flat panel display panel DP2 is formed into a rectangular shape in a plan view and the first flat panel display panel DP1 and its corresponding inner hole region are formed into a square shape, the second image display surface can be formed in the second flat panel display panel DP2 into at least one quadrilateral shape.

[0045] In embodiments where the second flat panel display panel DP2 is arranged in a shape such as a rectangle or a square in a plan view, the corresponding inner hole area of ​​the second flat panel display panel DP2 and the first flat panel display panel DP1 can also be formed in a circular shape in a plan view. In this embodiment, a second image display surface with a shape in which concave curves and straight lines are combined with each other can be formed in the second flat panel display panel DP2.

[0046] In an embodiment, the second foldable panel 120 includes a third flat panel display panel DP3 and a fourth flat panel display panel DP4. The third flat panel display panel DP3 has a circular or polygonal shape in a plan view, and the fourth flat panel display panel DP4 is foldably bound to (e.g., fixed to) the third flat panel display panel DP3.

[0047] In an embodiment, the third flat panel DP3 of the second foldable panel 120 can be formed in a circular or polygonal shape in a plan view. Figure 1 The illustration shows an embodiment in which the third flat panel display panel DP3 is formed in a plan view as a quadrilateral shape that is trapezoidal. However, the embodiments disclosed herein are not limited to this, and the third flat panel display panel DP3 may be formed in a plan view as a circular shape, or in a polygonal shape such as a triangle, a quadrilateral shape other than a trapezoid (e.g., a rhombus), a pentagon, or a hexagon.

[0048] In one embodiment, the end of the third flat panel display panel DP3 is assembled to (e.g., fixed to) a second folding module formed at the end of the fourth flat panel display panel DP4 (e.g., see...). Figure 5 HG2), and the rear surface of the third flat panel display panel DP3 can be folded into or unfolded from an inner hole region (such as the second inner hole region IHA2 defined in the fourth flat panel display panel DP4). For example, in an embodiment, the fourth flat panel display panel DP4 may have two surfaces formed at opposite ends (e.g., in the X-axis direction), and an inner hole region (such as the second inner hole region IHA2) formed by empty space. Figure 4 and Figure 5 It is set between two surfaces.

[0049] Reference Figure 1 In one embodiment, the third flat panel display panel DP3 can be folded in the -Y axis direction, and the rear surface of the third flat panel display panel DP3 can be incorporated into the interior of the inner hole region defined in the fourth flat panel display panel DP4.

[0050] When the third flat panel display panel DP3 and the fourth flat panel display panel DP4 are folded and joined together, they can be bound together in a plate shape in a planar view (e.g., fixed to each other). For example, in an embodiment, the third image display surface of the third flat panel display panel DP3 and the fourth image display surface of the fourth flat panel display panel DP4 can be arranged in the same way in a plate shape facing the Z-axis direction in a planar view. Conversely, the third flat panel display panel DP3 can be unfolded in the Z-axis direction and in the Y-axis direction opposite to the -Y-axis direction, so that the second foldable panel 120 does not form a plate shape.

[0051] In an embodiment, the fourth flat panel DP4 of the second foldable panel 120 is formed in a circular or polygonal shape in a plan view, and an inner hole region (such as the second inner hole region IHA2) is formed at the center portion of the front surface including the other side surface of the fourth flat panel DP4, having a shape corresponding to the outline shape and size (e.g., area) of the third flat panel DP3 in a plan view.

[0052] In an embodiment, the shape and dimensions (e.g., area) of the fourth flat panel display panel DP4 in a plan view are the same as those of the second flat panel display panel DP2 in a plan view. For example, the fourth flat panel display panel DP4 may be formed in a plan view in a shape such as a rectangle, square, circle, or ellipse. For example, in an embodiment, the fourth flat panel display panel DP4 may be formed in a rectangular shape in a plan view, the rectangle having a relatively long side formed in the lateral direction, which is the X-axis direction.

[0053] The fourth image display surface of the fourth flat panel display panel DP4 is formed in at least one side surface direction of the inner hole region to surround at least one side surface of the inner hole region (such as the second inner hole region IHA2) formed at the central portion of the fourth flat panel display panel DP4. For example, one or two of the right-angled triangular surfaces formed at opposite ends of the fourth flat panel display panel DP4 (e.g., in the X-axis direction) may be the fourth image display surface.

[0054] Based on the shape of the fourth flat panel DP4 in the plan view and the shape of the inner hole area corresponding to the third flat panel DP3 in the plan view, a fourth image display surface with a semi-circular shape, a cylindrical or cylindrical shape, or a polygonal shape (such as a triangular shape or a quadrilateral shape) in the plan view can be formed on the front surface direction of the fourth flat panel DP4.

[0055] like Figure 1As shown, in an embodiment where the fourth flat panel display panel DP4 is formed into a rectangular shape in a plan view and the third flat panel display panel DP3 and the inner hole region (such as the second inner hole region IHA2) are formed into a trapezoidal shape, a fourth image display surface having a right-angled triangular shape is formed in the fourth flat panel display panel DP4. In an embodiment where the fourth flat panel display panel DP4 is formed into a rectangular shape in a plan view and the third flat panel display panel DP3 and the corresponding inner hole region (such as the second inner hole region IHA2) are formed into a square shape, the fourth image display surface may be formed into at least one quadrilateral shape in the fourth flat panel display panel DP4.

[0056] In an embodiment where the fourth flat panel DP4 is arranged in a shape such as a rectangle or a square in the plan view, the third flat panel DP3 and the inner hole area can also be formed in a circular shape in the plan view. In this embodiment, a fourth image display surface with a shape in which concave curves and straight lines are combined with each other can be formed in the fourth flat panel DP4.

[0057] The first flat panel display panel DP1 and the second flat panel display panel DP2 of the first foldable panel 100, and the third flat panel display panel DP3 and the fourth flat panel display panel DP4 of the second foldable panel 120 can be classified in various ways according to the display method. For example, in embodiments, the first flat panel display panel DP1, the second flat panel display panel DP2, the third flat panel display panel DP3, and the fourth flat panel display panel DP4 can be classified and constructed as micro-light-emitting diode (LED) display panels, nano-LED display panels, liquid crystal display panels, plasma display panels, field emission display panels, electrophoretic display panels, organic light-emitting diode display panels, inorganic light-emitting display panels, and quantum dot light-emitting display panels, etc. In the following, for ease of explanation, organic light-emitting diode display panels will be described as examples of the first flat panel display panel DP1, the second flat panel display panel DP2, the third flat panel display panel DP3, and the fourth flat panel display panel DP4 according to embodiments, and unless specifically distinguished, organic light-emitting diode display panels used in embodiments will be abbreviated as first flat panel display panel DP1, second flat panel display panel DP2, third flat panel display panel DP3, and fourth flat panel display panel DP4. However, the first flat panel display panel DP1, the second flat panel display panel DP2, the third flat panel display panel DP3, and the fourth flat panel display panel DP4 according to the embodiments are not limited to organic light-emitting diode display panels, and can be other display devices listed above or known in the art without departing from this disclosure.

[0058] Figure 2 It is shown Figure 1A block diagram showing the detailed components of the first foldable panel. Figure 2 It specifically shows the composition. Figure 1 A block diagram showing the detailed components of the first flat panel display panel DP1 and the second flat panel display panel DP2 is shown. Furthermore, Figure 3 It is specifically shown Figure 2 The second flat panel display panel shown is a side sectional view.

[0059] Reference Figure 2 and Figure 3 In an embodiment, each display panel (e.g., each of the first flat panel display panel DP1 and the second flat panel display panel DP2) includes at least one image display surface DA, a touch sensing unit TSU, a scan driving circuit 210, a data driving circuit 200, and a display driving circuit 400. In an embodiment, the display driving circuit 400 may be formed only in either the first flat panel display panel DP1 or the second flat panel display panel DP2.

[0060] As an example, in one embodiment, the image display surface DA of the first flat panel DP1 can be formed on the front surface of the display unit DU, and can include multiple pixels SP and display images through the multiple pixels SP. In another embodiment, the display unit DU can include a substrate SUB, a thin film transistor layer TFTL, an emitter layer EML, and a thin film encapsulation layer TFEL.

[0061] In an embodiment, a touch sensing unit (TSU) for sensing touches from human body parts (such as fingers) and electronic pens can be disposed on an image display surface (DA). The touch sensing unit (TSU) can be mounted on the front surface portion of the image display surface (DA) or integrally formed with it. In an embodiment, such a touch sensing unit (TSU) may include multiple touch electrodes, and the touch electrodes are used to capacitively sense the user's touch.

[0062] The scan driving circuit 210, in response to the gate control signal from the display driving circuit 400, supplies gate scan signals to the pixels SP of each horizontal line through the gate lines GL of each horizontal line of the image display surface DA. The scan driving circuit 210 sequentially drives the pixels SP of each horizontal line by sequentially supplying the gate scan signals to the gate lines GL of each horizontal line.

[0063] In one embodiment, the data driving circuit 200 may include multiple data driving integrated circuits. The data driving circuit 200 outputs data voltages according to image data to the pixels SP of the image display surface DA based on data driving control signals from the display driving circuit 400. In another embodiment, the data driving integrated circuits can supply data voltages to the data lines DL connected to each pixel SP in each horizontal cycle, on a horizontal line basis.

[0064] The display driving circuit 400 can operate as a main processor or can be integrated with the main processor. Therefore, the display driving circuit 400 can control the overall function of the first flat panel display panel DP1 and the second flat panel display panel DP2. For example, in one embodiment, the display driving circuit 400 classifies external image data and supplies the classified image data to the data driving integrated circuit of the data driving circuit 200, and controls the driving timing of the data driving circuit 200. Furthermore, the display driving circuit 400 controls the gate scan signal output timing of the scan driving circuit 210. Additionally, the display driving circuit 400 generates data control signals to control the data voltage output timing of the data driving integrated circuit included in the data driving circuit 200.

[0065] In this embodiment, the display driving circuit 400 can detect touch coordinate information included in the touch data of the touch sensing unit (TSU), and then generate digital image data based on the touch coordinate information. Furthermore, the display driving circuit 400 can execute an application indicated by an icon displayed at the user's touch coordinates. As another example, the display driving circuit 400 can receive coordinate data from an electronic pen or the like, determine the touch coordinates of the electronic pen, and then generate digital image data or execute an application indicated by an icon displayed at the touch coordinates of the electronic pen.

[0066] Reference Figure 3 The second flat panel display panel DP2 can be divided into a main region MA and a sub-region SBA. The main region MA may include an image display surface DA and a non-display region NDA. The image display surface DA includes pixels SP that display images, and the non-display region NDA (e.g., in the X and Y axis directions) is disposed around the image display surface DA. In the image display surface DA, images can be displayed by emitting light from the emission region or aperture region of each pixel SP. In an embodiment, the pixels SP of the image display surface DA may include pixel circuits, pixel defining films, and self-emissive elements. The pixel circuits include switching elements, and the pixel defining films define emission regions or aperture regions.

[0067] The non-display area NDA can be any outer region or external region of the image display surface DA (e.g., in the X-axis and / or Y-axis direction). The non-display area NDA can be defined as the edge region of the main region MA of the first flat panel display panel DP1. In an embodiment, fan-out lines connecting the scan drive circuit 210, data drive circuit 200, and display drive circuit 400 to the image display surface DA can be formed in the non-display area NDA.

[0068] The sub-region SBA can extend from one side of the main region MA. In embodiments, the sub-region SBA can be formed as a film made of a flexible material that can be bent, folded, and rolled. For example, when the sub-region SBA is bent, it can overlap with the main region MA in the thickness direction (e.g., the Z-axis direction). In embodiments, the sub-region SBA may include data driving circuitry 200 and pad (also referred to as "solder pad") components connected to the circuit board 300. However, embodiments of this disclosure are not necessarily limited thereto. For example, in embodiments, the sub-region SBA may be omitted, and the data driving circuitry 200 and pad components may be disposed in the non-display area NDA.

[0069] In embodiments, the data driving circuit 200 can be formed as multiple integrated circuits (ICs) and mounted on the respective display panels DP1 and DP2 using a chip-on-glass (COG) method, a chip-on-plastic (COP) method, or an ultrasonic bonding method. As an example, the data driving circuit 200 can be disposed in a sub-region SBA and can be superimposed on the main region MA in the thickness direction (e.g., the Z-axis direction) by bending the sub-region SBA. As another example, the data driving circuit 200 can be mounted on a circuit board 300.

[0070] In an embodiment, the circuit board 300 can be electrically connected to the pad components of the display unit DU via an anisotropic conductive film (ACF). For example, leads of the circuit board 300 can be electrically connected to the pad components of the display unit DU. In an embodiment, the circuit board 300 can be a flexible printed circuit board, a printed circuit board, or a flexible film such as a chip-on-film.

[0071] In this embodiment, the display driving circuit 400 may be mounted on the circuit board 300. For example, the display driving circuit 400 may be formed as an integrated circuit (IC).

[0072] Figure 4 yes Figure 1 A perspective view of the unfolded form and disassembled structure of each of the first and second foldable panels shown.

[0073] Reference Figure 4The end of the first foldable panel 100 can be attached to (e.g., fixed to) one end of the second foldable panel 120 or detached from one end of the second foldable panel 120. For example, in an embodiment, the first flat panel DP1 and the second flat panel DP2 of the first foldable panel 100 can be detached from the third flat panel DP3 and the fourth flat panel DP4 of the second foldable panel 120. Therefore, the first foldable panel 100 and the second foldable panel 120 can be used in a flat panel display device in a detached state.

[0074] In an embodiment, the first flat panel display panel DP1 is connected via a first folding module (e.g., see...). Figure 5 The first flat panel display panel DP1 is bound and assembled (e.g., fixed to) one end of the second flat panel display panel DP2. Therefore, the first flat panel display panel DP1 can be unfolded in the -Y axis direction with one end of the first flat panel display panel DP1 bound to the first folding module, and the rear surface of the first flat panel display panel DP1 can be separated from the inner hole region (such as the first inner hole region IHA1) of the second flat panel display panel DP2.

[0075] In this embodiment, the first flat panel display panel DP1 unfolds in the Z-axis direction according to the setting direction of the first folding module, so that the first flat panel display panel DP1 can be set and maintained at an angle of 90° relative to the second flat panel display panel DP2.

[0076] In an embodiment, one end of the second foldable panel 120 can be attached to the other end of the first foldable panel 100, or detached from the other end of the first foldable panel 100. For example, in an embodiment, the third flat panel DP3 and the fourth flat panel DP4 of the second foldable panel 120 can be detached from the first flat panel DP1 and the second flat panel DP2 of the first foldable panel 100. The first foldable panel 100 and the second foldable panel 120 can be used in a flat panel display device in their detached state.

[0077] In an embodiment, the third flat panel display panel DP3 is connected via a second folding module (e.g., see...). Figure 5 The HG2 is bound and assembled (e.g., fixed to) the end of the fourth flat panel display panel DP4. Therefore, the third flat panel display panel DP3 can be unfolded in the Z-axis and Y-axis directions with the end of the third flat panel display panel DP3 bound by the second folding module, and the rear surface of the third flat panel display panel DP3 can be separated from the inner hole region (such as the second inner hole region IHA2) of the fourth flat panel display panel DP4.

[0078] In this embodiment, the third flat panel display panel DP3 unfolds in the Z-axis and Y-axis directions according to the setting direction of the second folding module, so that the third flat panel display panel DP3 can be set and maintained at a 90° angle relative to the fourth flat panel display panel DP4.

[0079] Figure 5 It is shown Figure 4 The plan view of the unfolded structure of each of the first and second foldable panels shown.

[0080] Reference Figure 5 The first flat panel display panel DP1 can be unfolded in the Z-axis and -Y-axis directions with one end of the first flat panel display panel DP1 bound to the first folding module HG1 (e.g., fixed to the first folding module HG1), and the rear surface of the first flat panel display panel DP1 can be separated from the inner hole area (such as the first inner hole area IHA1) of the second flat panel display panel DP2.

[0081] In this embodiment, the first flat panel display panel DP1 unfolds in the Z-axis and -Y-axis directions according to the setting direction of the first folding module HG1, so that the first flat panel display panel DP1 can be set and maintained at an angle of 180° relative to the second flat panel display panel DP2.

[0082] Furthermore, the third flat panel display panel DP3 is bound and assembled (e.g., fixed to) the end of the fourth flat panel display panel DP4 via the second folding module HG2. Therefore, in this embodiment, the third flat panel display panel DP3 can be unfolded in the Z-axis and Y-axis directions while its end is bound by the second folding module HG2, and the rear surface of the third flat panel display panel DP3 can be separated from the inner hole region (such as the second inner hole region IHA2) of the fourth flat panel display panel DP4.

[0083] In this embodiment, the third flat panel display panel DP3 unfolds in the Z-axis and Y-axis directions according to the setting direction of the second folding module HG2, so that the third flat panel display panel DP3 can be set and maintained at an angle of 180° relative to the fourth flat panel display panel DP4.

[0084] Figure 6 It is shown Figure 4 and Figure 5 A perspective view of the three-dimensional arrangement and assembly structure of the first and second foldable panels shown. Furthermore, Figure 7 This is a side view of the first and second foldable panels, which are set and assembled in three-dimensional shape.

[0085] Reference Figure 6 and Figure 7 In an embodiment, the first flat panel display panel DP1 can be unfolded along the Z-axis and -Y-axis directions with one end of the first flat panel display panel DP1 bound to the first folding module HG1 (e.g., fixed to the first folding module HG1), and the rear surface of the first flat panel display panel DP1 can be separated from the inner hole region (such as the first inner hole region IHA1) of the second flat panel display panel DP2.

[0086] In this embodiment, the first flat panel display panel DP1 unfolds along the Z-axis and -Y-axis according to the setting direction of the first folding module HG1, so that the first flat panel display panel DP1 can be set and held at a 90° angle relative to the second flat panel display panel DP2. For example, in this embodiment, when the relatively shorter side of the second flat panel display panel DP2 is set in the Y-axis direction, the relatively shorter side of the first flat panel display panel DP1 unfolds along the Z-axis according to the setting direction of the first folding module HG1, so that the first flat panel display panel DP1 and the second flat panel display panel DP2 can be set and held at a 90° angle relative to each other.

[0087] In an embodiment, the third flat panel display panel DP3 can be unfolded along the Z-axis and Y-axis directions with its ends bound to the second folding module HG2 (e.g., fixed to the second folding module HG2), and the rear surface of the third flat panel display panel DP3 can be separated from the inner hole region (such as the second inner hole region IHA2) of the fourth flat panel display panel DP4.

[0088] In this embodiment, the third flat panel display panel DP3 unfolds in the Z-axis and Y-axis directions according to the setting direction of the second folding module HG2, so that the third flat panel display panel DP3 can be set and held at a 90° angle relative to the fourth flat panel display panel DP4. For example, when the relatively shorter side of the fourth flat panel display panel DP4 is set in the Y-axis direction, the relatively shorter side of the third flat panel display panel DP3 unfolds in the Z-axis direction according to the setting direction of the second folding module HG2, so that the third flat panel display panel DP3 and the fourth flat panel display panel DP4 can be set and held at a 90° angle relative to each other.

[0089] Reference Figure 6 and Figure 7In one embodiment, one end of a first flat panel display panel DP1, which is set and held at a 90° angle, is bound (e.g., fixed to) one end of a third flat panel display panel DP3, which is set and held at a 90° angle. Furthermore, one end of a second flat panel display panel DP2, which is set and held at a 90° angle, can be bound to one end of a fourth flat panel display panel DP4, which is set and held at a 90° angle.

[0090] Therefore, the first flat panel display panel DP1 and the fourth flat panel display panel DP4 can be arranged parallel to each other in any direction (such as the direction relative to the long side), and the second flat panel display panel DP2 and the third flat panel display panel DP3 can also be arranged parallel to each other in any direction (such as the direction relative to the long side).

[0091] In an embodiment, the second flat panel display panel DP2 and the third flat panel display panel DP3 may be maintained and set apart from each other by a first gap wy1 (e.g., in the Z-axis direction), the first gap wy1 corresponding to the length of each of the first flat panel display panel DP1 and the fourth flat panel display panel DP4 in the direction of their relative short sides.

[0092] Furthermore, in the embodiments, the first flat panel display panel DP1 and the fourth flat panel display panel DP4 may be maintained and set apart from each other by a second spacing wy2 (e.g., in the Y-axis direction), the second spacing wy2 corresponding to the length of each of the second flat panel display panel DP2 and the third flat panel display panel DP3 in the direction of their relative short sides.

[0093] The first image display surface of the first flat panel display panel DP1 and the fourth image display surface of the fourth flat panel display panel DP4 are oriented in the same direction as the side surface direction (e.g., the same first direction, such as the -Y direction). Conversely, the second image display surface of the second flat panel display panel DP2 and the third image display surface of the third flat panel display panel DP3 may be oriented in the same direction as the first and fourth image display surfaces (e.g., the same second direction, such as the Z-axis direction), which is 90° different from the first and fourth image display surfaces.

[0094] Figure 8 It is shown in Figure 7 A front view of the image display surfaces of the first and fourth flat panel display panels as seen from the line of sight in the XY direction of the arrows.

[0095] Reference Figure 8In an embodiment in which one end of a first flat panel display panel DP1, which is set and held at a 90° angle, is bound (e.g., fixed) to one end of a third flat panel display panel DP3, which is set and held at a 90° angle, and one end of a second flat panel display panel DP2, which is set and held at a 90° angle, is bound (e.g., fixed) to one end of a fourth flat panel display panel DP4, which is set and held at a 90° angle, the first flat panel display panel DP1 and the fourth flat panel display panel DP4 may be set parallel to each other in any direction (such as the direction relative to the long side).

[0096] The first flat panel display panel DP1 and the fourth flat panel display panel DP4 (e.g., in the Y-axis direction) are maintained and set with a second spacing wy2 corresponding to the length of each of the second flat panel display panel DP2 and the third flat panel display panel DP3 in the relative short side direction, while being set parallel to each other in any direction (such as the relative long side direction).

[0097] Based on the second distance wy2 between the first flat panel display panel DP1 and the fourth flat panel display panel DP4 (e.g., in the Y-axis direction), the first image display surface of the first flat panel display panel DP1 and the fourth image display surface of the fourth flat panel display panel DP4 also maintain the second distance wy2. Therefore, a three-dimensional effect is generated based on the distance difference between the first displayed image on the first image display surface and the fourth displayed image on the fourth image display surface (e.g., in the Y-axis direction). For example, in the line of sight in the XY arrow direction, a three-dimensional effect is generated based on the distance difference between the first displayed image on the first image display surface and the fourth displayed image on the fourth image display surface.

[0098] Figure 9 It shows along Figure 7 The top view of the image display surfaces of the second and third flat panel display panels viewed from the direction of the ZX arrow.

[0099] Reference Figure 7 and Figure 9 The second flat panel display panel DP2 and the third flat panel display panel DP3 can also be set parallel to each other in any direction (such as the direction relative to the long side).

[0100] The second flat panel display panel DP2 and the third flat panel display panel DP3 (e.g., in the Z direction) are maintained and set with a first spacing wy1 corresponding to the length of each of the first flat panel display panel DP1 and the fourth flat panel display panel DP4 in the direction of the relatively short side.

[0101] Based on the first pitch wy1 between the second flat panel display panel DP2 and the third flat panel display panel DP3 (e.g., in the Z direction), the second image display surface of the second flat panel display panel DP2 and the third image display surface of the third flat panel display panel DP3 also maintain the first pitch wy1. Therefore, a three-dimensional effect is generated based on the distance difference between the third displayed image on the third image display surface and the second displayed image on the second image display surface (e.g., in the Z direction). For example, in a line of sight in the ZX arrow direction, a three-dimensional effect is generated based on the distance difference between the second displayed image on the second image display surface and the third displayed image on the third image display surface.

[0102] Figure 10 This is a perspective view showing a display device according to an embodiment of the present disclosure.

[0103] Reference Figure 10 The first flat panel display panel DP1 of the first foldable panel 100 can be formed into a circular shape in a plan view.

[0104] In one embodiment, one end of the first flat panel display panel DP1 is assembled to a first folding module formed at one end of the second flat panel display panel DP2, and the rear surface of the first flat panel display panel DP1 is folded into or unfolded from an inner hole region formed in the second flat panel display panel DP2.

[0105] For example, in one embodiment, the first flat panel display panel DP1 can be folded in the Y-axis direction, and the rear surface of the first flat panel display panel DP1 can be coupled to the inner hole region of the second flat panel display panel DP2. In another embodiment, the inner hole region of the second flat panel display panel DP2 can be formed as a groove shape having a rear surface closed by a rear surface cover, or as a hole shape having an open rear surface.

[0106] When the first flat panel DP1 and the second flat panel DP2 are folded and joined together, the rear surface of the first flat panel DP1 is folded into the inner hole area formed in the second flat panel DP2, and the first foldable panel 100 can be formed into a plate shape.

[0107] In an embodiment, in addition to the circular shape in the plan view, the second flat panel display panel DP2 can also be formed in the plan view as a polygonal shape such as a rectangle or a square.

[0108] In one embodiment, an inner hole region having a shape corresponding to the outline shape and size (e.g., area) of the first flat panel display panel DP1 in a plan view is formed at the center portion of the front surface including one side surface of the second flat panel display panel DP2. For example, in one embodiment, the second flat panel display panel DP2 may be formed as a rectangle in a plan view, the rectangle having a relatively long side formed in the lateral direction, the lateral direction being the X-axis direction.

[0109] A second image display surface of the second flat panel display panel DP2 is formed in the direction of at least one side surface of the inner hole region to surround at least one side surface of the inner hole region. Depending on the shape of the second flat panel display panel DP2 in a plan view and the shape of the inner hole region corresponding to the first flat panel display panel DP1 in a plan view, a second image display surface having a semi-circular shape, a cylindrical or cylindrical shape, or a polygonal shape (such as a triangular or quadrilateral shape) in the plan view can be formed in the direction of the front surface of the second flat panel display panel DP2. Figure 10 As shown in the embodiment, a second image display surface having a shape in which concave curves and straight lines are combined with each other can be formed in the second flat panel display panel DP2.

[0110] In one embodiment, the third flat panel DP3 of the second foldable panel 120 may also be formed in a circular shape in the plan view to correspond to the first flat panel DP1. In another embodiment, one end of the third flat panel DP3 is assembled to a second folding module formed at one end of the fourth flat panel DP4, and the rear surface of the third flat panel DP3 is folded into or unfolded from an inner hole region formed in the fourth flat panel DP4.

[0111] When the third flat panel DP3 and the fourth flat panel DP4 are folded and joined together, the rear surface of the third flat panel DP3 is folded into the inner hole area formed in the fourth flat panel DP4, and the second foldable panel 120 can be formed into a plate shape.

[0112] In an embodiment, in addition to the circular shape in the plan view, the fourth flat panel display panel DP4 can also be formed in the plan view as a polygonal shape such as a rectangular shape or a square shape. In an embodiment, an inner hole region having a shape corresponding to the outline shape and size (e.g., area) of the third flat panel display panel DP3 in the plan view is formed at the central portion of the front surface including one side surface of the fourth flat panel display panel DP4.

[0113] In an embodiment, a fourth image display surface of the fourth flat panel DP4 is formed in the direction of at least one side surface of the inner hole region to surround at least one side surface of the inner hole region. Based on the shape of the fourth flat panel DP4 in a plan view and the shape of the inner hole region corresponding to the third flat panel DP3 in a plan view, a fourth image display surface having a shape in which concave curves and straight lines are combined with each other can be formed in the direction of the front surface of the fourth flat panel DP4.

[0114] Furthermore, in an embodiment in which one end of a first flat panel display panel DP1, which is set and held at a 90° angle, is bound to the other end of a third flat panel display panel DP3, which is set and held at a 90° angle, and one end of a second flat panel display panel DP2, which is set and held at a 90° angle, is bound to (e.g., fixed to) one end of a fourth flat panel display panel DP4, which is set and held at a 90° angle, the first flat panel display panel DP1 and the fourth flat panel display panel DP4 can be set parallel to each other in any direction (such as the direction relative to the long side).

[0115] Based on the spacing between the first flat panel display panel DP1 and the fourth flat panel display panel DP4, the first image display surface of the first flat panel display panel DP1 and the fourth image display surface of the fourth flat panel display panel DP4 also maintain a second spacing wy2. Therefore, a three-dimensional effect is generated based on the distance difference between the first displayed image on the first image display surface and the fourth displayed image on the fourth image display surface.

[0116] Based on the spacing between the second flat panel display panel DP2 and the third flat panel display panel DP3, the second image display surface of the second flat panel display panel DP2 and the third image display surface of the third flat panel display panel DP3 also maintain a first spacing wy1. Therefore, a three-dimensional effect is generated based on the distance difference between the third display image on the third image display surface and the second display image on the second image display surface.

[0117] In summarizing the detailed description, those skilled in the art will understand that many variations and modifications can be made to the described embodiments without substantially departing from the principles of this disclosure. Therefore, the embodiments described in this disclosure are used in a general and descriptive sense only and not for limiting purposes.
