Description

display device

[0001] The present invention relates to a display device, and more particularly, to a display device in which a hole is formed in a portion of a display panel and an external device is added to the hole.

[0002] When the display panel is produced as a finished product, the display panel may have a fixed shape, such as a rectangle or a square. However, when the display device intends to place an external device together with the display panel, a portion of the display panel may be cut out and the external device may be placed in the cut out area.

[0003] A display panel includes a display area containing a plurality of pixels and a non-display area where no pixels are arranged. The display area generates an image through the pixels, and the non-display area may not generate an image.

[0004] Meanwhile, pixels in the display area must be connected to signal lines such as data lines and gate lines to receive the voltage required for image generation.

[0005] Therefore, when selecting a cutting area of ​​a display panel, whether data lines and gate lines can be connected to pixels in the display area around the cutting area can be an important factor.

[0006] The problem to be solved by the present invention is to provide a display device including a display panel and an external device arranged in an opening of the display panel.

[0007] Another problem to be solved by the present invention is to provide a display device in which data voltage and gate voltage can be transmitted to pixels adjacent to the opening even if an opening is formed in the display panel.

[0008] The tasks of the present invention are not limited to the tasks mentioned above, and other technical tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0009] According to one embodiment of the present invention for solving the above problem, a display device comprises a first substrate; and a second substrate facing the first substrate and having one side and the other side facing the one side; wherein the display panel includes an opening recessed inward from at least one side, the display panel includes a display area defined on the first substrate and including a plurality of pixels, a first non-display area positioned above, left, right, and below the display area, and a second non-display area formed by surrounding the opening and forming the first non-display area on the lower side and the opening, the second non-display area being formed between the first non-display area and the opening, and a sum of a width of the opening and a width of the second non-display area becoming narrower toward the inside or being the same.

[0010] It may further include an external device placed in the above opening.

[0011] The above opening may include a curved surface.

[0012] It may further include a printed circuit board attached to a first non-display area located above the display area and having a data driving circuit mounted thereon.

[0013] It may further include a plurality of data lines extending from the data driving circuit and respectively connected to the plurality of pixels.

[0014] The data line may include a first data line extending from the data driving circuit to a first non-display area located below, and a second data line terminating in the second non-display area.

[0015] It may further include a first gate driving circuit arranged in a first non-display area located on the left side of the display area, and a second gate driving circuit arranged in a first non-display area located on the right side.

[0016] It may further include a plurality of gate lines extending from the first and second gate driving circuits and respectively connected to the plurality of pixels.

[0017] The gate line may include a first gate line extending from the first gate driving circuit to the second gate driving circuit, and a second gate line ending in the second non-display area.

[0018] In the second non-display area, a resin layer may further be disposed on the side of the first substrate and the side of the second substrate.

[0019]

[0020] *In the second non-display area, the side of the first substrate can be aligned with the side of the second substrate.

[0021] In the second non-display area, the side surface of the first substrate may protrude toward the hole more than the side surface of the second substrate.

[0022] In the second non-display area, the side surface of the second substrate may protrude toward the hole more than the side surface of the first substrate.

[0023] The width of the above opening may become narrower as it goes inward.

[0024] The above opening may have a semicircular shape or a semi-elliptical shape.

[0025] The width of the above opening may increase as it goes inward or may remain the same.

[0026] The above opening can be indented from the right side and the lower side of the display panel.

[0027] The above opening can be indented from the left side and the lower side of the display panel.

[0028] When viewed from the bottom, the above opening may become narrower as it goes inward, and when viewed from the left or right, the opening may become wider and then narrower as it goes inward.

[0029] The above opening is formed by being indented in a first direction from at least one side, and based on a virtual line extending along a second direction passing through the opening, the number of points of contact between the virtual line and the opening may be two or less.

[0030] Specific details of other embodiments are included in the detailed description and drawings.

[0031] According to a display device according to one embodiment, by forming an opening in a display panel and placing an external device in the opening, it may be possible to eliminate the need for providing a separate space for placing an external device.

[0032] In addition, even if an opening is formed in the display panel, the sum of the width of the opening and the width of the second non-display area is designed to become narrower or identical as it goes inward, so that data voltages and gate voltages can be transmitted to pixels adjacent to the opening without interruption. As a result, expansion of the non-display area of ​​the display panel (or expansion of the bezel area) can be prevented.

[0033] The effects according to the embodiments are not limited to those exemplified above, and more diverse effects are included in this specification.

[0047] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms. These embodiments are provided solely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined solely by the scope of the claims.

[0048] When elements or layers are referred to as being "on" another element or layer, this includes both directly over the other element or layer and intervening layers or elements. Like reference numerals refer to like elements throughout the specification.

[0049] Although terms like "first" and "second" are used to describe various components, these components are not limited by these terms. These terms are used merely to distinguish one component from another. Therefore, it should be understood that a "first" component referred to below may also be a "second" component within the technical scope of the present invention.

[0050] Hereinafter, specific embodiments will be described with reference to the attached drawings.

[0051] Figure 1 is a plan view of a display device according to one embodiment.

[0052] Referring to FIG. 1, a display device (1) according to one embodiment may include a display panel (10) and an external device (20) positioned around the display panel (10). The external device (20) may include a coin inserting device, a receipt printer, or a card reader, but the embodiments of the present specification are not limited thereto.

[0053] When the display panel is produced as a finished product, for example, the display panel may have a standardized shape such as a rectangle or a square. However, when the display device further includes an external device, the external device is additionally placed on the right, left, upper, or lower side of the display panel, and thus, due to the area occupied by the external device (20), the placement space of the display device (1) may become larger, or problems such as aesthetics being impaired may occur.

[0054] However, when a part of the display panel (10) is cut and an external device (20) is placed in the cut area, the placement space of the display device (1) can be used efficiently, and the aesthetics can also be improved.

[0055] Meanwhile, there are also problems in setting the cutting area of ​​the display panel (10) and in setting the shape of the cutting area. These problems will be described later after explaining the overall structure of the display device (1).

[0056] As illustrated in FIG. 1, a display device (1) may include a display panel (10), a printed circuit film (COF), a data driving circuit (DIC), gate driving circuits (GDC1, GDC2), and an external device (20). An opening (HP) in which the external device (20) is placed may be formed in the display panel (10). The opening (HP) in the present specification may be a concept including a groove or a hole. For example, when the opening (HP) includes a groove, the groove may mean a pattern recessed inward (or inside) from one side of the display panel (10). In this case, as in FIG. 1, at least one side of the groove may be open, but the other sides may be a structure surrounded by a component (or structure) of the display panel (10). As another example, when the opening (HP) includes a hole, the hole may mean a pattern formed on the inside (or inside) of the display panel (10). In this case, although not shown, all sides of the hole may be a structure surrounded by the composition (or structure) of the display panel (10). The hole may include a curved shape.

[0057] The display panel (10) may have a rectangular shape consisting of long sides extending along a first direction (DR1) and short sides extending along a second direction (DR2). However, the embodiments of the present specification are not limited thereto, and the display panel (10) may have a shape such as a square, an ellipse, a circle, or other polygons. For convenience of explanation, the following description will focus on the display panel (10) having a rectangular shape.

[0058] However, an opening (HP) is formed in the display panel (10), and the opening (HP) may be formed in at least one side of the display panel (10). For example, the opening (HP) may be formed in the other long side of the display panel (10) in the second direction (DR2). The opening (HP) may be formed by being recessed inward from at least one side of the display panel (10). For example, the opening (HP) may be formed by being recessed toward the inside of the display panel (10) from the other long side in the second direction (DR2).

[0059] The planar shape of the opening (HP) may be a rectangle with sharp corners or a rectangle with rounded corners. When the shape of the opening (HP) is a rectangle with rounded corners, the opening (HP) may include a curved shape. By including a curved shape, the opening (HP) can prevent cracks from occurring around the opening (HP) during the process of forming the opening (HP). In some embodiments, the opening (HP) may have a semicircular or semi-elliptical shape, but the embodiments of the present specification are not limited thereto.

[0060] A more detailed explanation of the aperture (HP) will be provided later.

[0061] The display panel (10) may include a display area (DA) and a non-display area (NDA). The display area (DA) may include a plurality of pixels (PX), and the non-display area (NDA) may be located around the display area (DA). For example, the planar shape of the display area (DA) may be similar to the general planar shape of the display panel (10). For example, the planar shape of the display area (DA) may be rectangular, but is not limited thereto and may be a square, an ellipse, a circle, or other polygonal shape.

[0062] A non-display area (NDA) can surround a display area (DA). For example, the non-display area (NDA) can completely surround the display area (DA) in a plane. For example, the non-display area (NDA) can be located above, to the right, to the left, and below the display area (DA), respectively. For example, the non-display area (NDA) can include a first non-display area (NDA1) located above, to the right, and to the left of the display area (DA), and a second non-display area (NDA2) located below the display area (DA).

[0063] The opening (HP) may be formed by being recessed inward from the lower side (or the other side in the second direction (DR2)) of the display panel (10), and the second non-display area (NDA2) may surround the opening (HP) in a planar manner. For example, the second non-display area (NDA2) may be positioned between the opening (HP) and the display area (DA) in a planar manner. The first non-display area (NDA1) may also be positioned below the display area (DA) and may be connected to the second non-display area (NDA2) at the lower side of the display area (DA). The second non-display area (NDA2) may be positioned between the first non-display area (NDA1) and the opening (HP).

[0064] A printed circuit film (COF) may be attached to a first non-display area (NDA1) above a display area (DA). A plurality of printed circuit films (COFs) may be provided. The plurality of printed circuit films (COFs) may be spaced apart from each other in a first direction (DR1). A data drive circuit (DIC) may be mounted on each printed circuit film (COF).

[0065] The gate driving circuit (GDC) may include a first gate driving circuit (GDC1) and a second gate driving circuit (GDC2). The first gate driving circuit (GDC1) may be located in a first non-display area (NDA1) on the left side of the display area (DA), and the second gate driving circuit (GDC2) may be located in a first non-display area (NDA20) on the right side of the display area (DA). A gate line (GL) may extend from each gate driving circuit (GDC1, GDC2), and a data line (DL) may extend from each data driving circuit (DIC). The gate line (GL) and the data line (DL) may each be electrically connected to a pixel (PX).

[0066] Meanwhile, as illustrated in FIG. 1, virtual lines (IL1, IL2) may be formed in the display device (1). The virtual lines (IL1, IL2) may each extend along the first direction (DR1). In the case of the display device (1) according to one embodiment, the number of contact points between the virtual lines (IL1, IL2) extending along the first direction (DR1) and the opening (HP) may be two or less. For example, the first virtual line (IL1) may have one contact point, and the second virtual line (IL2) may have two contact points. The virtual lines (IL1, IL2) are associated with the gate line (GL).

[0067] Figure 2 is a plan view of a display device according to another embodiment.

[0068] The display device (1) according to Fig. 2 differs from the display device (1) according to Fig. 1 in that the planar shape of the opening (HP) is a trapezoid with a constant taper. For example, the long side of the opening (HP) may be located on the outside, and the cross-section may be located on the inside. The corners of the opening (HP) may be rounded, but as illustrated in Fig. 2, they may also be angled.

[0069] Fig. 3 is a plan view additionally illustrating the gate line and data line of the display device of Fig. 1. In Fig. 3, a semicircular or elliptical shaped opening (HP) is illustrated as being applied, rather than the planar shape of the opening (HP) of Fig. 1.

[0070] Referring to FIGS. 1 and 3, the data line (DL) may include a first data line (DL1) extending from a printed circuit film (COF) (or a data driving circuit (DIC)) in a second direction (DR2), and a second data line (DL2) extending from the printed circuit film (COF) (or a data driving circuit (DIC)) in a second direction (DR2) but ending in a second non-display area (NDA2).

[0071] The gate line (GL) may include a gate line (GL1, GL2) extending from a first gate driving circuit (GDC1) or a second gate driving circuit (GDC2). For example, the first gate line (GL1) may extend from the first gate driving circuit (GDC1) in a first direction (DR1) and extend to a first non-display area (NDA1) on the opposite side, and the second gate line (GL2) may extend from the first gate driving circuit (GDC1) in the first direction (DR1) and terminate at a second non-display area (NDA2).

[0072] In the second non-display area (NDA2), pixels (PX) are not arranged, and an image may not be displayed. In the case of the display device (1) according to one embodiment, since the gate driving circuit (GDC) is arranged in the first non-display area (NDA1) on the left and right sides, respectively, even if the second gate line (GL2) is disconnected by the opening (HP) and the second non-display area (NDA2), a gate voltage can be provided to the pixels (PX) of the display area (DA) around the opening (HP) and the second non-display area (NDA2). However, as described above, when there are three or more contact points where the virtual line (IL) extending along the first direction (DR1) and the second non-display area (NDA2) or the opening (HP) come into contact, the gate line (GL) does not extend to the display area (DA) between the contact points, so there is a problem that the bezel area increases. However, in the case of the display device (1) according to one embodiment, since there are two or fewer contact points between the virtual line (IL) extending along the first direction (DR1) and the second non-display area (NDA2) or the opening (HP), a display area (DA) that the gate line (GL) cannot reach may not occur.

[0073] In addition, from the perspective of the data line (DL), the data line (DL) may be connected to all pixels (PX) of the display area (DA) of the display device (1) according to one embodiment. That is, in the case of the display device (1) according to one embodiment, as illustrated in FIG. 3, the sum (W) of the width of the opening (HP) and the width of the second non-display area (NDA2) may become narrower from the end (or lower side) of the display panel (10) toward the inside, or may have the same structure. Hereinafter, for the convenience of explanation, the opening (HP) and the second non-display area (NDA2) will be collectively referred to as the bezel area (BA). That is, the width (W) of the bezel area (BA) may become narrower from the end (or lower side) of the display panel (10) toward the inside, or may have the same structure. When the width (W) of the bezel area (BA) increases from the end (or lower side) of the display panel (10) toward the inside, pixels (PX) of the display area (DA) to which the data lines (DL) cannot extend may exist. However, in one embodiment, the width (W) of the bezel area (BA) becomes narrower or remains the same from the end (or lower side) of the display panel (10) toward the inside, so that a display area (DA) to which the data lines (DL) cannot reach may not occur.

[0074] Figure 4 is a cross-sectional view taken along line AA' of Figure 1.

[0075] Referring to FIG. 4, a display panel (see 10 in FIG. 1) may include a first substrate (SUB1), a second substrate (SUB2), a first polarizing layer (POL1), and a second polarizing layer (POL2). The first substrate (SUB1) may be a TFT substrate, and the second substrate (SUB2) may be a color filter substrate. The first substrate (SUB1) may include pixels (PX) arranged at each intersection of gate lines (GL in FIG. 1) and data lines (DL in FIG. 1). The pixel (PX) may include at least one thin film transistor, an anode electrode, and a cathode electrode. When the display panel (see 10 in FIG. 1) is a QLED, a quantum dot film may be additionally included on the lower surface of the first substrate (SUB1), but the embodiments of the present specification are not limited thereto.

[0076] When the display panel (see 10 in FIG. 1) is an organic light-emitting display panel, an organic light-emitting layer may be disposed between the anode electrode and the cathode electrode, the first substrate (SUB1) may include a TFT substrate and an organic material, and the second substrate (SUB2) may be a metal reflective substrate. The first polarizing layer (POL1) and the second polarizing layer (POL2) may not be included.

[0077] When the display panel (see 10 in Fig. 1) is a liquid crystal display panel, a liquid crystal layer may be arranged between the anode electrode and the cathode electrode.

[0078] Thin film transistors are switching elements that transmit and control electrical signals to each pixel.

[0079] The anode electrode can be electrically connected to a thin film transistor.

[0080] The second substrate (SUB2) may include a color filter and a black matrix. The color filter may have R (red), G (green), and B (blue) patterns formed thereon. The black matrix may be positioned between the R, G, and B patterns of the color filter.

[0081] The second polarization layer (POL2) may be attached to the upper portion of the second substrate (SUB2), and the first polarization layer (POL1) may be attached to the lower portion of the first substrate (SUB1). A first bonding layer (AM1) may be disposed between the first polarization layer (POL1) and the first substrate (SUB1), thereby bonding the first polarization layer (POL1) and the first substrate (SUB1), and a second bonding layer (AM2) may be disposed between the second polarization layer (POL2) and the second substrate (SUB2), thereby bonding the second polarization layer (POL2) and the second substrate (SUB2).

[0082] The first polarizing layer (POL1) and the second polarizing layer (POL2) have different polarizing functions through stretching processes in opposite directions, and can have contractile forces in opposite directions according to stretching.

[0083] The printed circuit film (COF) described above in FIG. 1 may be electrically connected to the first substrate (SUB1). The printed circuit film (COF) may be attached to the lower surface of the first substrate (SUB1), but the embodiments of the present specification are not limited thereto, and may be attached to the upper surface of the first substrate (SUB1). When the printed circuit film (COF) is attached to the upper surface of the first substrate (SUB1), the first substrate (SUB1) may protrude further outwardly compared to the second substrate (SUB2) in the first non-display area (NDA1) above the display area (DA). That is, the printed circuit film (COF) may be attached to the upper surface of the first substrate (SUB1) that protrudes further outwardly compared to the second substrate (SUB2) in the first non-display area (NDA1) above the display area (DA).

[0084] Figure 5 is a cross-sectional view taken along line BB' of Figure 1.

[0085] Referring to FIG. 5, on the second non-display area (NDA2), the side surfaces of the first substrate (SUB1) and the side surfaces of the second substrate (SUB2) may be aligned in the thickness direction, and the external device (20) may be spaced apart from the second non-display area (NDA2) by a predetermined distance, but the embodiments of the present specification are not limited thereto. On the opening (HP), a resin layer (RL) may be additionally disposed between the side surfaces of the substrates (SUB1, SUB2) and the external device (20). The resin layer (RL) may include an organic material, and the hardness of the resin layer (RL) may be lower than the hardness of the substrates (SUB1, SUB2). The resin layer (RL) may protect the side surfaces of the substrates (SUB1, SUB2) exposed by the opening (HP).

[0086] Hereinafter, a display device according to another embodiment will be described. In describing the embodiments below, redundant descriptions of drawing symbols or components already described in FIGS. 1 to 5 will be omitted.

[0087] Fig. 6 is a cross-sectional view of a display device according to another embodiment.

[0088] Referring to FIG. 6, in the second non-display area (NDA2) of the display device (2) according to the present embodiment, the side surface of the first substrate (SUB1) may protrude toward the opening (HP) more than the side surface of the second substrate (SUB2). Accordingly, the resin layer (RL) may also be in direct contact with the upper surface of the first substrate (SUB1).

[0089] Other detailed descriptions are omitted as they are described above in Fig. 5.

[0090] Fig. 7 is a cross-sectional view of a display device according to another embodiment.

[0091] Referring to FIG. 7, in the second non-display area (NDA2) of the display device (3) according to the present embodiment, the side surface of the second substrate (SUB2) may protrude more toward the opening (HP) than the side surface of the first substrate (SUB1). Accordingly, the resin layer (RL) may also be in direct contact with the lower surface of the second substrate (SUB2).

[0092] Other detailed descriptions are omitted as they are described above in Fig. 5.

[0093] Fig. 8 is a plan view of a display device according to another embodiment.

[0094] Referring to FIG. 8, the display device (4) according to the present embodiment differs from the display device (1) according to FIG. 1 in that the width of the second non-display area (NDA2) may be different. As described above with reference to FIG. 1, the width of the second non-display area (NDA2) may be uniform around the opening (HP). However, in the case of the display device (4) according to FIG. 8, the width of the opening (HP) may increase as it approaches the display area (DA). On the other hand, the sum (W) of the width of the opening (HP) and the width of the second non-display area (NDA2) may decrease as it approaches the display area (DA), similar to FIG. 1.

[0095] As in the present embodiment, even if the width of the opening (HP) increases as it goes inward, if the width of the second non-display area (NDA2) is adjusted so that the sum (W) of the width of the opening (HP) and the width of the second non-display area (NDA2) is designed to become narrower as it gets closer to the display area (DA), the data line (DL) can be electrically connected to all pixels (PX) of the display area (DA).

[0096] Other detailed descriptions are omitted as they are described in Fig. 1.

[0097] Fig. 9 is a plan view of a display device according to another embodiment.

[0098] Referring to FIG. 9, the display device (5) according to the present embodiment differs from the display device (1) according to FIG. 1 in that the width of the second non-display area (NDA2) may be different. As described above with reference to FIG. 1, the width of the second non-display area (NDA2) may be uniform around the opening (HP). However, in the case of the display device (5) according to FIG. 9, the width of the opening (HP) may increase as it approaches the display area (DA). On the other hand, the sum (W) of the width of the opening (HP) and the width of the second non-display area (NDA2) may be designed to be uniform.

[0099] As in this embodiment, even if the width of the opening (HP) increases as it goes inward, if the width of the second non-display area (NDA2) is adjusted so that the sum (W) of the width of the opening (HP) and the width of the second non-display area (NDA2) is designed to be uniform overall, the data line (DL) can be electrically connected to all pixels (PX) of the display area (DA).

[0100] Other detailed descriptions are omitted as they are described in Fig. 1.

[0101] Fig. 10 is a plan view of a display device according to another embodiment.

[0102] Referring to FIG. 10, the opening (HP) of the display device (6) according to the present embodiment is different from the display device (1) according to FIG. 1 in that it can be formed at the right and lower corners of the display panel (10).

[0103] To be more specific, the opening (HP) of the display device (6) can be formed at the right and lower corners of the display panel (10).

[0104] In the present embodiment, the opening (HP) can be formed at two sides of the display panel (10). That is, the opening (HP) can be formed at the lower side and the right side of the display panel (10). In the present embodiment, the width of the opening (HP) and the width of the second non-display area (NDA2) must satisfy two conditions. For example, the sum (Wa) of the width of the opening (HP) and the width of the second non-display area (NDA2) in the direction viewed from the lower side of the display panel (10) must become smaller or the same as the direction toward the inside, and the sum (Wb) of the width of the opening (HP) and the width of the second non-display area (NDA2) in the direction viewed from the right side of the display panel (10) must become smaller or the same as the direction toward the inside.

[0105] Other detailed descriptions are omitted as they are described above in Fig. 1.

[0106] Fig. 11 is a plan view of a display device according to another embodiment.

[0107] Referring to FIG. 11, the opening (HP) of the display device (7) according to the present embodiment is different from the display device (6) according to FIG. 10 in that it can be formed at the right and lower corners of the display panel (10).

[0108] To be more specific, the opening (HP) of the display device (6) can be formed at the right and lower corners of the display panel (10).

[0109] In the present embodiment, the opening (HP) can be formed at two sides of the display panel (10).
