[0002] This application claims priority to Korean Patent Application No. 10-2020-0021039, filed on February 20, 2020, the entire contents of which are incorporated herein by reference. Technical Field
[0003] The inventive concept described herein relates to a display device. Background Technology
[0004] Electronic devices that provide images to users, such as smartphones, digital cameras, laptops, navigation devices, and smart TVs, include display devices configured to display images. The display device includes a display panel configured to generate images and an input device, such as an input detection section.
[0005] An input detection unit is located on the display panel and detects the user's touch. The signal detected by the input detection unit is converted into an input signal. The display panel provides the user with an image corresponding to the input signal from the input detection unit.
[0006] The display device includes a polarizing film disposed on the display panel to prevent the reflection of external light.

The polarizing film reduces the reflectivity of external light incident from the outside of the display device toward the display panel. Inventively, the polarizing film (POL) may include a phase retarder and / or a polarizer. However, due to the thickness of the polarizing film, the thickness of the display device can be increased when using a polarizing film.

[0115] The first detection portion SP1, the second detection portion SP2, and the extended pattern EP can be disposed on the same layer. The first conductive pattern CP can be disposed on a different layer from the first detection portion SP1, the second detection portion SP2, and the extended pattern EP.

[0117] For example, Figure 8 The diagram illustrates two first detection portions SP1 that are adjacent to each other and spaced apart from each other, and two second detection portions SP2 that are adjacent to each other and connected to each other.
[0118] refer to Figure 8 , Figure 9 and Figure 10 Each of the first detection portion SP1 and the second detection portion SP2 may include a plurality of first branch portions BP1 extending in the first diagonal direction DDR1 and a plurality of second branch portions BP2 extending in the second diagonal direction DDR2. The first branch portions BP1 and the second branch portions BP2 are combined to have a grid shape.
[0119] The first diagonal direction DDR1 can be defined as a direction that intersects the first direction DR1 and the second direction DR2 on a plane defined by the first direction DR1 and the second direction DR2. The second diagonal direction DDR2 can be defined as a direction that intersects the first diagonal direction DDR1 on a plane defined by the first direction DR1 and the second direction DR2. For example, the first direction DR1 and the second direction DR2 can intersect each other perpendicularly, and the first diagonal direction DDR1 and the second diagonal direction DDR2 can intersect each other perpendicularly.

[0122] An extended pattern EP can be disposed between the first detection portions SP1 and can extend from the second detection portion SP2. The second detection portion SP2 and the extended pattern EP can be integrally formed. The extended pattern EP has a grid shape and can extend from each of the second detection portions SP2.

The extended pattern EP, the first detection portion SP1, and the second detection portion SP2 disposed on the same layer can be defined as a second conductive pattern.
[0123] The first conductive pattern CP may include a first extension EX1 and a second extension EX2 having a shape symmetrical to the first extension EX1. The extension pattern EP may be disposed between the first extension EX1 and the second extension EX2.
[0124] The first extension EX1 can extend through an area overlapping with one of the second detection portions SP2, and can be connected to the upper and lower first detection portions SP1. The second extension EX2 can extend through another area overlapping with the second detection portion SP2, and can be connected to the upper and lower first detection portions SP1.
[0125] exist Figure 8 and Figure 9 In the accompanying drawings, based on the relative arrangement positions, the first detection portion SP1 is referred to as the upper first detection portion SP1 and the lower first detection portion SP1. Furthermore, based on the relative arrangement positions in the accompanying drawings, the second detection portion SP2 is defined as the left second detection portion SP2 and the right second detection portion SP2.
[0126] The predetermined portions of the first extension portion EX1 and the second extension portion EX2 adjacent to one side of the first extension portion EX1 and the second extension portion EX2 can be connected to the lower first detection portion SP1 through multiple contact holes TC-CH. The predetermined portions of the first extension portion EX1 and the second extension portion EX2 adjacent to the other side of the first extension portion EX1 and the second extension portion EX2 can be connected to the upper first detection portion SP1 through multiple contact holes TC-CH.
[0127] The contact hole TC-CH is defined in an insulating layer disposed on the first conductive pattern CP, and will be described below. Figure 11 The diagram shows the structure of the contact hole TC-CH.
[0128] The first extension EX1 may include a first sub-extension EX1_1 and a second sub-extension EX1_2 extending in the first diagonal direction DDR1, a third sub-extension EX1_3 and a fourth sub-extension EX1_4 extending in the second diagonal direction DDR2, a first sub-conductive pattern SCP1 extending in the second diagonal direction DDR2, and a second sub-conductive pattern SCP2 extending in the first diagonal direction DDR1. The first sub-conductive pattern SCP1 is a part of the fourth sub-extension EX1_4. The second sub-conductive pattern SCP2 is a part of the second sub-extension EX1_2.
[0129] The predetermined portions of the first sub-extension EX1_1 and the second sub-extension EX1_2 adjacent to one side of the first sub-extension EX1_1 and the second sub-extension EX1_2 can be connected to the lower first detection portion SP1 at region A through multiple contact holes TC-CH. The predetermined portions of the third sub-extension EX1_3 and the fourth sub-extension EX1_4 adjacent to one side of the third sub-extension EX1_3 and the fourth sub-extension EX1_4 can be connected to the upper first detection portion SP1 at region B through multiple contact holes TC-CH.
[0130] The other side of the first sub-extension EX1_1 can extend from the other side of the third sub-extension EX1_3 and is adjacent to the other side of the third sub-extension EX1_3. The other side of the second sub-extension EX1_2 can extend from the other side of the fourth sub-extension EX1_4 and is adjacent to the other side of the fourth sub-extension EX1_4. The first sub-conductive pattern SCP1 can extend from the other side of the fourth sub-extension EX1_4 in the second diagonal direction DDR2 and can extend to the first sub-extension EX1_1. The second sub-conductive pattern SCP2 can extend from the other side of the second sub-extension EX1_2 in the first diagonal direction DDR1 and can extend to the third sub-extension EX1_3.
[0131] The first sub-extension EX1_1, the second sub-extension EX1_2, the third sub-extension EX1_3, the fourth sub-extension EX1_4, the first sub-conductive pattern SCP1, and the second sub-conductive pattern SCP2 can be formed as a single unit.
[0132] The first sub-extension EX1_1 and the second sub-extension EX1_2 can be extended to intersect with a predetermined number of second branch portions BP2 in the second branch portion BP2 of the right second detection portion SP2 that are adjacent to the lower first detection portion SP1. For example... Figure 9 As illustrated in the diagram, some parts of the first branch BP1 of the second detection section SP2 on the right may not be placed in the area overlapping with the first sub-extension EX1_1, the second sub-extension EX1_2, and the second sub-conductive pattern SCP2.
[0133] The third sub-extension EX1_3 and the fourth sub-extension EX1_4 can be extended to intersect with a predetermined number of first branch sections BP1 in the first branch section BP1 of the right second detection section SP2 that are adjacent to the upper first detection section SP1. For example... Figure 9 As illustrated in the diagram, some parts of the second branch BP2 of the second detection section SP2 on the right may not be placed in the area overlapping with the third sub-extension EX1_3, the fourth sub-extension EX1_4, and the first sub-conductive pattern SCP1.
[0134] The second extension EX2 may include a fifth sub-extension EX2_1 and a sixth sub-extension EX2_2 extending in the second diagonal direction DDR2, a seventh sub-extension EX2_3 and an eighth sub-extension EX2_4 extending in the first diagonal direction DDR1, a third sub-conductive pattern SCP3 extending in the first diagonal direction DDR1, and a fourth sub-conductive pattern SCP4 extending in the second diagonal direction DDR2.
[0135] The left second detection portion SP2 may have a structure symmetrical to the right second detection portion SP2, and the second extension portion EX2 may have a structure symmetrical to the first extension portion EX1. Therefore, the fifth sub-extension portion EX2_1 to the eighth sub-extension portion EX2_4 can be connected to the first detection portion SP1 through the left second detection portion SP2. Furthermore, predetermined portions of the fifth sub-extension portion EX2_1 to the eighth sub-extension portion EX2_4 can be connected to the first detection portion SP1 through multiple contact holes TC-CH.
[0136] The fifth sub-extension EX2_1 to the eighth sub-extension EX2_4 may intersect with some of the first branch BP1 and the second branch BP2 of the left second detection section SP2. Additionally, the first branch BP1 and the second branch BP2 of the left second detection section SP2 may not be located in areas overlapping with the fifth sub-extension EX2_1 to the eighth sub-extension EX2_4, as well as the third sub-conductive pattern SCP3 and the fourth sub-conductive pattern SCP4.
[0137] Figure 11 It is along Figure 8 The cross-sectional view taken from line I-I'.
[0138] refer to Figure 11 The input detection section (ISP) may further include an insulating layer (IOL) disposed on the thin-film encapsulation layer (TFE). The insulating layer (IOL) may include inorganic materials. An insulating layer (IOL) is illustrated, but is not limited thereto. Multiple inorganic insulating layers may be disposed on the thin-film encapsulation layer (TFE).
[0139] A first conductive pattern CP can be disposed on an insulating layer IOL. The first conductive pattern CP can be directly disposed on the insulating layer IOL. When multiple insulating layers IOL are provided, the first conductive pattern CP can be directly disposed on the uppermost insulating layer IOL. A first insulating layer TC-OL1 can be disposed on the first conductive pattern CP and the insulating layer IOL. The first insulating layer TC-OL1 may include an organic material.

An extended pattern EP integrally formed with the second detection portion SP2 can also be disposed on the first insulating layer TC-OL1. The first conductive pattern CP can be connected to the first detection portion SP1 through a plurality of contact holes TC-CH defined in the first insulating layer TC-OL1.

[0142] Figure 12 yes Figure 7 The image shows an enlarged view of the second region A2.
[0143] For example, Figure 12 The diagram illustrates the luminescent regions PA1, PA2, and PA3, as well as the first detection section SP1 and the second detection section SP2.
[0144] refer to Figure 12, Figure 6 The light-emitting region PA shown in the figure can be any one of the light-emitting regions PA1, PA2, and PA3. The light-emitting regions PA1, PA2, and PA3 can be arranged along the first diagonal direction DDR1 and the second diagonal direction DDR2. The first branch portion BP1 and the second branch portion BP2 of the first detection portion SP1 and the second detection portion SP2 can overlap with the non-light-emitting region NPA between the light-emitting regions PA1, PA2, and PA3.
[0145] The light-emitting areas PA1, PA2, and PA3 may include a plurality of first light-emitting areas PA1 configured to display red, a plurality of second light-emitting areas PA2 configured to display green, and a plurality of third light-emitting areas PA3 configured to display blue. The third light-emitting areas PA3 may be larger than the first light-emitting areas PA1, and the first light-emitting areas PA1 may be larger than the second light-emitting areas PA2.
[0146] The light-emitting areas PA1, PA2, and PA3 can be rhomboid in shape. The touch opening portion TOP can overlap with the light-emitting areas PA1, PA2, and PA3. The touch opening portion TOP can have a rhomboid shape or other polygonal shape corresponding to the shape of the light-emitting areas PA1, PA2, and PA3, and can have dimensions corresponding to the light-emitting areas PA1, PA2, and PA3.
[0147] Since the first detection section SP1 and the second detection section SP2 are set in the non-light-emitting region NPA, the light generated in the light-emitting regions PA1, PA2 and PA3 can be emitted normally without being affected by the first detection section SP1 and the second detection section SP2.
[0148] Figure 13 It is a schematic diagram. Figure 12 The diagram shows the cross-sectional configuration of the display panel and input detection section.
[0149] Figure 13 The luminescent region PA shown in the figure can correspond to Figure 12 The luminescent regions PA1, PA2, and PA3 are illustrated in the diagram. For example, Figure 13 The illustration shows that the light-emitting regions PA have the same size. Additionally, in... Figure 13 For example, the first conductive pattern CP, the first detection portion SP1, and the second detection portion SP2 are illustrated one by one.
[0150] refer to Figure 13The display panel (DP) may include multiple light-emitting areas (PAs) and non-light-emitting areas (NPAs) between the light-emitting areas (PAs). The input detection section (ISP) may include an insulating layer (IOL), a first conductive pattern (CP), a second conductive pattern (CNP2), a color filter layer (CF), a first insulating layer (TC-OL1), a black matrix (BM), and a second insulating layer (TC-OL2). The first insulating layer (TC-OL1), the black matrix (BM), and the second insulating layer (TC-OL2) can be respectively... Figure 11 The diagram shows the first insulating layer TC-OL1, the black matrix BM, and the second insulating layer TC-OL2.
[0151] A color filter layer CF and a first conductive pattern CP can be disposed on the thin-film encapsulation layer TFE of the display panel DP. Specifically, the color filter layer CF can overlap with the light-emitting area PA and can be disposed on the insulating layer IOL. The color filter layer CF can be directly disposed on the insulating layer IOL. When multiple insulating layers IOL are provided, the color filter layer CF can be directly disposed on the uppermost insulating layer IOL. The first conductive pattern CP can overlap with the non-light-emitting area NPA and can be disposed on the insulating layer IOL.
[0152] The color filter layer CF can extend to each adjacent portion of the non-luminescent region NPA and the luminescent region PA. The color filter layer CF can include multiple color filters CF1, CF2, and CF3. Color filters CF1, CF2, and CF3 can include a first color filter CF1, a second color filter CF2, and a third color filter CF3.
[0153] The first color filter CF1, the second color filter CF2, and the third color filter CF3 can have different colors. For example, the first color filter CF1, the second color filter CF2, and the third color filter CF3 can respectively include a red color filter, a green color filter, and a blue color filter.
[0154] The red filter can be set Figure 12 The green color filter can be set on the first luminescent area PA1 shown in the diagram. Figure 12 The blue filter can be set on the second luminescent area PA2 shown in the diagram. Figure 12 The third luminescent region PA3 is shown in the diagram.
[0155] Each of the first color filter CF1, the second color filter CF2, and the third color filter CF3 can extend into the portion of the non-luminescent region NPA adjacent to the corresponding luminescent region PA. The first color filter CF1, the second color filter CF2, and the third color filter CF3 can be spaced apart from each other in the non-luminescent region NPA. The larger middle portions of color filters CF1, CF2, and CF3 can be disposed in the luminescent region PA, while the smaller side portions are disposed in the non-luminescent region NPA.
[0156] The first conductive pattern CP can be disposed between some of the color filters CF1, CF2, and CF3. For example, the first conductive pattern CP can be disposed between the first color filter CF1 and the second color filter CF2. Figure 11 It is a cross-sectional view of the non-luminescent region NPA in which the first branch portion BP1 and the second branch portion BP2 are set, and therefore Figure 11 There is no illustration in the middle. Figure 13 The color filters CF1, CF2 and CF3 are shown in the diagram.
[0157] A first insulating layer TC-OL1 can be disposed on an insulating layer IOL. The first insulating layer TC-OL1 can be disposed on a first conductive pattern CP and a color filter layer CF. An opening portion OP overlapping with the light-emitting region PA can be defined in the first insulating layer TC-OL1. Therefore, the first insulating layer TC-OL1 can be disposed in the non-light-emitting region NPA to cover color filters CF1, CF2, and CF3 and the first conductive pattern CP. Color filters CF1, CF2, and CF3 can be exposed by the opening portion OP in the light-emitting region PA.
[0158] The side surface SLP of the first insulating layer TC-OL1, which defines the opening portion OP, can have an inclined surface forming an acute angle AAL relative to the upper surface of the display panel DP. For example, based on a direction parallel to the upper surface of the display panel DP, the width of the first insulating layer TC-OL1 can decrease in an upward direction perpendicular to the upper surface of the display panel DP. The width W1 of the first insulating layer TC-OL1 can be defined as the distance between the opening portions OP. The side surface SLP of the first insulating layer TC-OL1 can be defined as a reflective side surface. The first insulating layer TC-OL1 is mainly disposed in the non-light-emitting region NPA. The side surface SLP of the first insulating layer TC-OL1 can extend into the light-emitting region PA.
[0159] The second conductive pattern CNP2 can overlap with the non-light-emitting region NPA and can be disposed on the first insulating layer TC-OL1. The second conductive pattern CNP2 may include a first detection portion SP1 and a second detection portion SP2. Although in Figure 13 Not shown in the figure, but the second conductive pattern CNP2 may include an extended pattern EP extending from the second detection portion SP2. The second conductive pattern CNP2 may be connected to the first conductive pattern CP.
[0160] The black matrix BM can overlap with the non-emitting region NPA and can be disposed on the second conductive pattern CNP2. The black matrix BM can be disposed on the first insulating layer TC-OL1 to cover the second conductive pattern CNP2. The black matrix BM can be disposed entirely within the non-emitting region NPA.
[0161] The second insulating layer TC-OL2 can be disposed on the color filter layer CF, the first insulating layer TC-OL1, and the black matrix BM. The second insulating layer TC-OL2 can be configured to fill the opening portion OP. For example, the second insulating layer TC-OL2 can be provided on the color filter layer CF, the first insulating layer TC-OL1, and the black matrix BM using an inkjet process. The refractive index of the second insulating layer TC-OL2 can be greater than the refractive index of the first insulating layer TC-OL1.
[0162] The light L generated in the luminescent region PA can propagate upwards. Since the refractive index of the second insulating layer TC-OL2 is greater than that of the first insulating layer TC-OL1, total internal reflection can occur at the interface between the first insulating layer TC-OL1 and the second insulating layer TC-OL2. Therefore, the light L propagating towards the side surface SLP of the first insulating layer TC-OL1 can be reflected from the side surface SLP of the first insulating layer TC-OL1 and propagate upwards. As a result, the brightness in the luminescent region PA can be increased.
[0163] Black matrix (BM) can block unwanted light in the non-emitting area (NPA). Black matrix (BM) can include light-absorbing black material.
[0164] The first color filter CF1, the second color filter CF2, and the third color filter CF3 can convert external light into red, green, and blue. This external light can be directed towards the display panel DP and provided to the display device DD. If the first color filter CF1, the second color filter CF2, and the third color filter CF3 are not used, the external light can be reflected from the display panel DP and provided to the user. In this case, the external light is visible to the user, for example, light reflected from a mirror.
[0165] However, as illustrated and described, external light is supplied to the first color filter CF1, the second color filter CF2, and the third color filter CF3, so that it is absorbed by the first color filter CF1, the second color filter CF2, and the third color filter CF3, or converted into red, green, and blue in the first color filter CF1, the second color filter CF2, and the third color filter CF3. Therefore, even if external light is supplied to the display device DD, like the light-emitting area PA, the external light can be converted into red, green, and blue in the first color filter CF1, the second color filter CF2, and the third color filter CF3. As a result, reflection of external light is prevented, making the visibility of external light impossible.
[0166] A first layer, comprising a color filter layer CF and a black matrix BM, is disposed on the input detection section ISP, and a second layer, comprising a first insulating layer TC-OL1 and a second insulating layer TC-OL2, may be disposed on the first layer. In this case, the input detection section ISP may include other inorganic insulating layers and other organic insulating layers instead of the first insulating layer TC-OL1 and the second insulating layer TC-OL2. Additionally, an additional organic insulating layer may be disposed between the first and second layers.
[0167] Therefore, when the first and second layers are stacked on the input detection section (ISP) respectively, the number of organic insulating layers used may increase, the manufacturing process may become more complex, and the thickness of the display device (DD) may increase.
[0168] In embodiments of the present invention, the color filter layer CF, the black matrix BM, and the first insulating layer TC-OL1 and the second insulating layer TC-OL2 can be integrated and disposed in the input detection section ISP. Therefore, the number of organic insulating layers used is reduced, simplifying the process and reducing the thickness of the display device DD.
[0169] Figure 14 This is a schematic diagram illustrating a cross-sectional configuration of a display device according to another embodiment of the concept of the present invention.
[0170] For example, in Figure 14 In, with Figure 13 The corresponding cross-sections are shown as the cross-sections of the display panel DP and the input detection section ISP_1.

The black matrix BM can be disposed on the first conductive pattern CP. The black matrix BM can be disposed on the insulating layer IOL to cover the first conductive pattern CP. The first insulating layer TC-OL1 can be disposed on the black matrix BM.

The first conductive pattern CP can be connected to the first detection portion SP1 of some of the second conductive patterns CNP2 defined in the first insulating layer TC-OL1 and the black matrix BM through the contact hole TC-CH' defined in the first insulating layer TC-OL1 and the black matrix BM.
[0175] The second insulating layer TC-OL2 can be disposed on the color filter layer CF, the first insulating layer TC-OL1, and the second conductive pattern CNP2, and can fill the opening portion OP.

The first branch portions BP1 and the second branch portions BP2 may be integrally formed and disposed in the non-light-emitting region NPA. The touch opening portion TOP overlapping the light-emitting region PA may be defined by the first branch portions BP1 and the second branch portions BP2.
[0180] The planar area of the input detection section ISP_2 can include an active area AA and an inactive area NAA surrounding the active area AA. The detection section SP can be set within the active area AA, and the pad PD can be set within the inactive area NAA. The routing section SNL can connect to the detection section SP, extend into the inactive area NAA, and connect to the pad PD.
[0181] The input detection section ISP_2 can be driven in self-inductive mode to obtain coordinate information using a self-capacitance method. For example, each of the detection sections SP can be operated as both a drive electrode and a detection electrode. A drive signal can be applied to the detection section SP, and a detection signal can be output from the detection section SP.
