[0040] In the following description, the present invention will be described more fully with reference to the accompanying drawings, in which embodiments of the present invention are illustrated. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention.

[0041] The accompanying drawings and descriptions are to be regarded as illustrative and non-limiting in nature, and the same reference numerals refer to the same elements throughout the specification and drawings. Therefore, repeated descriptions may be omitted or briefly discussed.

[0042] Various thicknesses, lengths, and angles are shown in the accompanying drawings, and while the arrangements shown do represent embodiments of the present invention, it will be understood that various modifications to the thicknesses, lengths, and angles are possible within the spirit and scope of the present invention, and the present invention is not necessarily limited to the specific thicknesses, lengths, and angles shown.

[0043] It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, the element may be directly on the other element, or an intervening element may be present. Conversely, when an element is referred to as being "directly on" another element, no intervening element is present. Furthermore, in the specification, the phrases "on" or "above" indicate positioning on or below a portion of an object, and do not necessarily indicate positioning on the upper side of a portion of an object based on the direction of gravity.

[0044] Furthermore, throughout the instruction manual, the phrase "in a plane" refers to the target portion viewed from above, and the phrase "in a cross section" refers to the cross section formed by vertically cutting the target portion viewed from the side.

[0045] Figure 1 This is a top plan view of the light-emitting panel according to an embodiment of the present invention.

[0046] Reference Figure 1 According to an embodiment of the present invention, the light-emitting panel 1000 includes a plurality of unit pixels UNTs arranged on a plane parallel to a first direction DR1 and a second direction DR2. The plurality of unit pixels UNTs can emit light according to a data signal to display an image, or can serve as a light source by emitting light according to a data signal. When used as a light source, the light-emitting panel can function as a light source device that emits light in a direction substantially parallel to a third direction DR3, which is substantially perpendicular to the first direction DR1 and the second direction DR2.

[0047] On a plane, multiple unit pixels UNT can be arranged to form a matrix on the substrate 110, but the present invention is not limited thereto and can be arranged in various forms.

[0048] A unit pixel UNT may include multiple sub-pixels PX1, PX2, and PX3 that can emit light of different colors. For example, the multiple sub-pixels PX1, PX2, and PX3 may include a first sub-pixel PX1 that can emit light of a first color, a second sub-pixel PX2 that can emit light of a second color, and a third sub-pixel PX3 that can emit light of a third color. However, the present invention is not limited to this, and the number of sub-pixels included in a unit pixel UNT may be four or more. For example, the first color may be red, the second color may be blue, and the third color may be green, but they are not limited to these colors and may be various other basic colors.

[0049] like Figure 1 As shown, multiple sub-pixels PX1, PX2 and PX3 included in a unit pixel UNT can be arranged sequentially in one direction (e.g., the first direction DR1), but the present invention is not limited thereto and can be arranged in various forms.

[0050] Figure 1 The sub-pixels PX1, PX2, and PX3 shown can correspond to the light-emitting areas, which are areas capable of emitting light.

[0051] Figure 2 This is a top view of a unit pixel of the light-emitting panel according to an embodiment of the present invention.

[0052] Reference Figure 2 Each of the plurality of sub-pixels PX1, PX2, and PX3 included in a unit pixel UNTa according to an embodiment of the present invention may include a pixel electrode 191 capable of receiving data voltage. For example... Figure 1 As shown, pixel electrodes 191 comprising multiple sub-pixels PX1, PX2, and PX3 within a single pixel UNT can be arranged sequentially in one direction (e.g., a first direction DR1), but the present invention is not limited thereto and can be arranged in various forms. For example, the first sub-pixel PX1 and the second sub-pixel PX2 can be arranged alternately in the horizontal direction, and the third sub-pixel PX3 can be arranged in the vertical direction. For example, the first sub-pixel PX1 and the third sub-pixel PX3 can be arranged alternately in one diagonal direction, and the second sub-pixel PX2 and the third sub-pixel PX3 can be arranged alternately in another diagonal direction.

[0053] The planar shape of each pixel electrode 191 can be a polygon such as a rectangle, or various planar shapes such as a circle or an ellipse. Figure 2 An example is shown in which each pixel electrode 191 has a rectangle including a short side L2 and a long side L1 that is longer than the short side L2. When the short side L2 of each pixel electrode 191 extends in a first direction DR1 and the long side L1 extends in a second direction DR2, a plurality of sub-pixels PX1, PX2 and PX3 included in a unit pixel UNTa can be arranged in the first direction DR1.

[0054] The pixel electrodes 191 comprising multiple sub-pixels PX1, PX2, and PX3 within a single pixel UNTa can have substantially the same shape and size. For example, the length of the short side L2 of the pixel electrode 191 of each of the sub-pixels PX1, PX2, and PX3 within a single pixel UNTa can be the same, and the length of the long side L1 can also be the same. However, the present invention is not limited thereto, and the shape and size of the pixel electrodes 191 comprising multiple sub-pixels PX1, PX2, and PX3 within a single pixel UNTa can be different depending on the light-emitting characteristics of the sub-pixels PX1, PX2, and PX3 for each color.

[0055] The light-emitting area of ​​each of the sub-pixels PX1, PX2, and PX3 can correspond to the corresponding pixel electrode 191. The light-emitting area of ​​each of the sub-pixels PX1, PX2, and PX3 can be the same as the area of ​​the corresponding pixel electrode 191, and can be located within the area surrounded by the edge of the corresponding pixel electrode 191, and has an edge parallel to the edge of the pixel electrode 191.

[0056] Each pixel electrode 191 can receive data voltage through multiple contact holes 89. Among the multiple contact holes 89 to which each pixel electrode 191 is connected, the number of contact holes 89 arranged along the long side L1 can be greater than the number of contact holes 89 arranged along the short side L2. For example, the number of contact holes 89 adjacent to a short side L2 of the pixel electrode 191 can be one, and the number of contact holes 89 adjacent to the long side L1 can be two or more, and can vary depending on the length of the long side L1. When there are multiple contact holes 89 arranged along the short side L2 or the long side L1, the spacing between the multiple contact holes 89 arranged along one direction (e.g., a first direction DR1 or a second direction DR2) can be constant.

[0057] The multiple contact holes 89 to which each pixel electrode 191 is connected may or may not overlap with the rectangular portion of the corresponding pixel electrode 191. Figure 2 An example is shown in which the plurality of contact holes 89 to which each pixel electrode 191 is connected do not overlap with a rectangular portion of the corresponding pixel electrode 191. In this case, each pixel electrode 191 may include a plurality of protrusions 198 to overlap with and connect to the contact holes 89. Each protrusion 198 may have a shape that protrudes in a direction substantially perpendicular to the extending direction of the short side L2 or the long side L1 of the rectangle of each pixel electrode 191 in the plane. For example, the protrusion 198 extending from the short side L2 may extend in a direction substantially perpendicular to the extending direction of the short side L2, and the protrusion 198 extending from the long side L1 may extend in a direction substantially perpendicular to the extending direction of the long side L1.

[0058] At this point, the light-emitting area of ​​each of the sub-pixels PX1, PX2, and PX3 can be the same as the rectangular portion of each pixel electrode 191, or can be located within the edge of the rectangular portion. The light-emitting area of ​​each of the sub-pixels PX1, PX2, and PX3 can be non-overlapping with the protrusion 198.

[0059] Multiple contact holes 89 connected to pixel electrodes 191 of adjacent sub-pixels PX1, PX2, and PX3 can be positioned in the area between adjacent sub-pixels PX1, PX2, and PX3 in either a first direction DR1 or a second direction DR2. For example... Figure 2 As shown, a plurality of contact holes 89, which are respectively connected to two pixel electrodes 191 of adjacent sub-pixels PX1, PX2 and PX3 located in the area between adjacent sub-pixels PX1, PX2 and PX3, can be adjacent in the first direction DR1 or the second direction DR2 and aligned in the first direction DR1.

[0060] Each pixel electrode 191 can receive the same data voltage through a plurality of contact holes 89 that overlap with and are connected to the pixel electrode 191. The data voltages applied to the plurality of pixel electrodes 191 comprising a plurality of sub-pixels PX1, PX2, and PX3 included in a unit pixel UNTa can be the same or different. For example, the data voltages applied to the plurality of pixel electrodes 191 comprising a plurality of sub-pixels PX1, PX2, and PX3 included in a unit pixel UNTa can be independent.

[0061] Due to the decrease in data voltage applied on the first direction DR1 by two contact holes 89 (i.e., two contact holes 89 arranged along the two long sides L1 facing each other on the first direction DR1) that are spaced apart from each other and aligned on the first direction DR1, the length of the short side L2 of each pixel electrode 191 can be determined based on a predetermined reference that brightness degradation cannot be detected on the vertical centerline of the pixel electrode 191 (e.g., a centerline parallel to the second direction DR2). Under these conditions, even if the length of the long side L1 of each pixel electrode 191 is formed to be longer than the short side L2, the aperture (or opening) of each of the sub-pixels PX1, PX2, and PX3 can be enlarged without causing brightness degradation on the vertical centerline of each pixel electrode 191. Therefore, the aperture ratio (or aperture ratio) and uniformity of the light-emitting panel according to the embodiment can be improved. Furthermore, as Figure 1 As shown, the unit pixel UNT, which includes multiple sub-pixels PX1, PX2, and PX3 that can represent various basic colors, can be arranged repeatedly in a matrix form, thus uniformly emitting light of various colors, including white.

[0062] The spacing between the plurality of contact holes 89 arranged along the long side L1 of each pixel electrode 191 can be equal to or less than the length of the short side L2. Therefore, brightness non-uniformity due to voltage drop of each pixel electrode 191 according to the second direction DR2 can be prevented.

[0063] Next, we will refer to Figure 3 A light-emitting panel according to an embodiment of the present invention is described.

[0064] Figure 3 This is a top view of a unit pixel of the light-emitting panel according to an embodiment of the present invention.

[0065] Reference Figure 3 Although the unit pixel UNTb included in the light-emitting panel according to the embodiment of the present invention is largely the same as the unit pixel UNTa of the light-emitting panel according to the previously described embodiment, the plurality of contact holes 89 to which each pixel electrode 191 is connected may overlap with the rectangular portion of the corresponding pixel electrode 191. The plurality of contact holes 89 to which each pixel electrode 191 is connected may be arranged along the inner edge of the pixel electrode 191 and may be positioned closer to the inner edge than the center of the pixel electrode 191.

[0066] In this case, each pixel electrode 191 may not be included in the protruding portion of the previously described embodiments.

[0067] Because the multiple contact holes 89 connected to adjacent sub-pixels PX1, PX2, and PX3 are not located in the area between adjacent sub-pixels PX1, PX2, and PX3 on the first direction DR1 or the second direction DR2, the spacing between the pixel electrodes 191 of adjacent sub-pixels PX1, PX2, and PX3 can be smaller, the aperture of each of sub-pixels PX1, PX2, and PX3 can be wider, and the light-emitting area of ​​each of sub-pixels PX1, PX2, and PX3 can be wider. Therefore, the light-emitting aperture ratio of the light-emitting panel 1000 can be improved, and light with sufficient brightness can be emitted.

[0068] like Figure 2 As shown, among the plurality of contact holes 89 connected to adjacent sub-pixels PX1, PX2 and PX3, the contact holes 89 of each of the sub-pixels PX1, PX2 and PX3 arranged along the adjacent long side L1 can be adjacent in the first direction DR1 and substantially aligned with each other.

[0069] Next, we will refer to Figure 4 A light-emitting panel according to an embodiment of the present invention is described.

[0070] Figure 4This is a top view of a unit pixel of the light-emitting panel according to an embodiment of the present invention.

[0071] Reference Figure 4 The unit pixel UNTc included in the light-emitting panel according to an embodiment of the present invention is largely the same as the unit pixels UNTa and UNTb of the light-emitting panel according to the previously described embodiment. However, the unit pixel UNTc may further include at least one central contact hole 89c located approximately at the center of the area of ​​each pixel electrode 191 and overlapping with the pixel electrode 191. The central contact hole 89c may be located on the vertical centerline of each pixel electrode 191. Each pixel electrode 191 may also receive a data voltage through connection to the central contact hole 89c.

[0072] When an odd number of contact holes 89 are placed adjacent to the short side L2 of each pixel electrode 191, the contact hole 89 located at the center among the contact holes 89 adjacent to the short side L2 of each pixel electrode 191 can be aligned on the vertical centerline extending in the second direction DR2 of each pixel electrode 191. Conversely, when an even number of contact holes 89 are arranged along the short side L2 of each pixel electrode 191, the vertical centerline of each pixel electrode 191 can pass through the middle of two contact holes 89 located at the center of the contact holes 89 adjacent to the short side L2.

[0073] and Figure 4 Unlike the previous example, multiple center contact holes 89c can be positioned within the plane of each pixel electrode 191. In this case, the multiple center contact holes 89c can be arranged along the vertical centerline of each pixel electrode 191.

[0074] The number of center contact holes 89c placed in each of the multiple sub-pixels PX1, PX2 and PX3 included in a unit pixel UNTc can be the same or different from each other.

[0075] Each pixel electrode 191 can receive the same data voltage through a plurality of overlapping and connected contact holes 89 and at least one central contact hole 89c. If a data voltage is applied through the central contact hole 89c, brightness degradation of the central portion of the pixel electrode 191 due to voltage drop can be prevented, and light with uniform brightness can be emitted by increasing the aperture. Therefore, the aperture ratio and uniformity of the light-emitting panel according to the embodiment can be improved.

[0076] Next, we will refer to Figure 5 A light-emitting panel according to an embodiment of the present invention is described.

[0077] Figure 5 This is a top view of a unit pixel of the light-emitting panel according to an embodiment of the present invention.

[0078] Reference Figure 5 The unit pixel UNTd included in the light-emitting panel according to an embodiment of the present invention is the same as that described above. Figure 2 The unit pixel UNTa of the light-emitting panel in the embodiment is mostly the same, but a plurality of contact holes 89 connected to the pixel electrodes 191 of adjacent sub-pixels PX1, PX2 and PX3 located in the area between adjacent sub-pixels PX1, PX2 and PX3 located in the first direction DR1 or the second direction DR2 can be arranged alternately along the first direction DR1 or the second direction DR2.

[0079] For example, a plurality of contact holes 89 located in the area between two adjacent sub-pixels PX1, PX2 and PX3 on the first direction DR1 can be aligned on the second direction DR2, and the contact holes 89 connected to the pixel electrode 191 of the sub-pixel located on the left and the contact holes 89 connected to the pixel electrode 191 of the sub-pixel located on the right can be alternately positioned along the second direction DR2 and can not be aligned with each other along the first direction DR1.

[0080] Multiple contact holes 89 located in the area between two adjacent sub-pixels PX1, PX2 and PX3 in the second direction DR2 can be aligned in the first direction DR1, and contact holes 89 connected to the pixel electrode 191 of the sub-pixel located on the upper side of the plane and contact holes 89 connected to the pixel electrode 191 of the sub-pixel located on the lower side of the plane can be alternately positioned along the first direction DR1.

[0081] Therefore, the area between adjacent sub-pixels PX1, PX2 and PX3 on the first direction DR1 or the second direction DR2 can be reduced, thereby allowing the aperture of each of the sub-pixels PX1, PX2 and PX3 to be wider, increasing the light emission aperture ratio of the light-emitting panel 1000, and enabling it to emit light with sufficient brightness.

[0082] Next, we will refer to Figure 6 The present invention describes a pixel circuit PXC included in or connected to a sub-pixel of a light-emitting panel according to an embodiment of the present invention.

[0083] Figure 6 This is a pixel circuit diagram of a sub-pixel of a light-emitting panel according to an embodiment of the present invention.

[0084] Reference Figure 6A pixel circuit PXC may include multiple transistors T1, T2, T3, T4, T5, T6, and T7 connected to multiple signal lines 151, 152, 153, 154, 171, and 172, as well as a capacitor Cst. The pixel circuit PXC is connected to a light-emitting diode ED, which serves as a light-emitting element, to transmit data voltage. The light-emitting diode ED may include a pixel electrode 191, as described previously, serving as the anode.

[0085] Signal lines 151, 152, 153, 154, 171, and 172 may include multiple scan lines 151, 152, and 154, control line 153, data line 171, and drive voltage line 172.

[0086] Scan lines 151, 152, and 154 can transmit scan signals GWn, GIn, and GI(n+1), respectively. Scan signals GWn, GIn, and GI(n+1) can transmit gate on-state voltages and gate off-state voltages that enable transistors T2, T3, T4, and T7 to turn on or off.

[0087] Scan lines 151, 152, and 154 may include a first scan line 151 capable of transmitting a scan signal GWn, a second scan line 152 capable of transmitting a scan signal GIn with a gate on-state voltage at a timing different from that of the first scan line 151, and a third scan line 154 capable of transmitting a scan signal GI(n+1). The second scan line 152 may transmit the gate on-state voltage at a timing earlier than that of the first scan line 151. For example, when the scan signal GWn is the nth scan signal (where n is a natural number 1 or greater) among the scan signals applied during a frame, the scan signal GLn may be a previous scan signal such as the (n-1)th scan signal, and the scan signal GI(n+1) may be the nth scan signal.

As described above, a pixel electrode 191 may be electrically connected to the connection member 79 via multiple contact holes 89 and / or a central contact hole 89c to receive data voltage. For example, pixel electrodes 191 may directly contact and connect to the connection member 79 via contact holes 89 and / or a central contact hole 89c.

[0130] A fifth insulating layer 350 (e.g., a pixel defining layer) may be positioned on the fourth insulating layer 141. The fifth insulating layer 350 may have an opening 351 positioned to overlap with the pixel electrode 191. The fifth insulating layer 350 may comprise an organic insulating material such as a polyacrylic resin or a polyimide resin.

[0131] The light-emitting layer 370 is positioned on the pixel electrode 191. The light-emitting layer 370 may include a portion positioned within an opening 351 of the fifth insulating layer 350. The light-emitting layer 370 may include an organic light-emitting material or an inorganic light-emitting material.

[0132] The common electrode 270 can be positioned on the light-emitting layer 370. The common electrode 270 can also be formed on the fifth insulating layer 350 and continuously distributed across multiple sub-pixels PX1, PX2, and PX3. The common electrode 270 may include a conductive transparent material.

[0133] The pixel electrode 191, the light-emitting layer 370, and the common electrode 270 can together form a light-emitting diode ED, and one of the pixel electrode 191 or the common electrode 270 can be a cathode and the other can be an anode.

[0134] The opening 351 of the fifth insulating layer 350 can define the light-emitting area of ​​each of the sub-pixels PX1, PX2, and PX3. For example... Figure 8 As shown, the opening 351 may be located within the edge of each pixel electrode 191, or alternatively, the opening 351 may be substantially aligned with the edge of each pixel electrode 191.

[0135] Reference Figure 8 The contact hole 89 may not overlap with the light-emitting area of ​​the light-emitting diode ED on the third-direction DR3. In this case, as described above... Figure 2 or Figure 5 In this embodiment, the contact hole 89 overlaps with the protrusion 198 of the pixel electrode 191, such that the protrusion 198 of the pixel electrode 191 can be electrically connected to the connecting member 79 and to the sixth transistor T6 through the contact hole 89. In this embodiment, the top of the contact hole 89 can be covered by a fifth insulating layer that serves as the pixel defining layer.

[0136] Next, we will refer to Figure 9 as well as Figure 7 and Figure 8 To describe the light-emitting panel according to an embodiment of the present invention.

[0137] Figure 9 It is a section taken along line A1-A2. Figure 7 The image shows a cross-sectional view of the light-emitting panel.

[0138] Reference Figure 9 Also refer to Figure 4 The light-emitting panel according to an embodiment of the present invention is as described above. Figure 7 and Figure 8 The light-emitting panels of the embodiments shown are mostly the same, but the pixel electrode 191 can be indirectly electrically connected to the connecting member 79 through another conductor, and does not directly contact the connecting member 79 through the contact hole 89 and / or the center contact hole 89c.

[0139] For example, contact holes 89 and / or center contact holes 89c can be filled with conductors 146 formed before stacking pixel electrodes 191, and pixel electrodes 191 can be electrically connected to the connection member 79 by contacting conductors 146. Conductors 146 can be electrically connected by direct contact with the connection member 79. Therefore, pixel electrodes 191 can be electrically connected to the connection member 79 via conductors 146 and receive data voltage.

[0140] The upper surface of the fourth insulating layer 141, which forms the contact hole 89 and / or the center contact hole 89c, and the upper surface of the conductor 146 are substantially at the same height, allowing for the formation of a planar surface. For example, the upper surfaces of the fourth insulating layer 141 and the conductor 146 can be substantially coplanar. Therefore, in the manufacturing process of the light-emitting panel, after forming the contact hole 89 and / or the center contact hole 89c in the fourth insulating layer 141, conductive material can be stacked and the upper surface of the conductive material can be polished, so that the conductor 146 remains only in the contact hole 89 and / or the center contact hole 89c, and then the upper surface of the substrate 110 can be flat. Next, when the pixel electrode 191 is formed on the upper surface of the substrate 110, the lower and upper surfaces of the pixel electrode 191 can be flat. Therefore, the pixel electrode 191 and the light-emitting diode ED can be formed on a flat surface without bending, thereby preventing defects in the light-emitting diode ED.

[0141] Even if the contact hole 89 and / or the center contact hole 89c overlap with the opening of each sub-pixel that serves as the light-emitting area, defects in the light-emitting diode (ED) can be prevented. Therefore, as described above... Figure 3 or Figure 4Similar to the light-emitting panel of the embodiment shown, multiple contact holes 89 and a central contact hole 89c can be placed within the rectangular portion of the pixel electrode 191, that is, within the portion overlapping with the light-emitting area. Therefore, the spacing between the pixel electrodes 191 of adjacent sub-pixels can become smaller, the opening of each sub-pixel can become wider, and the light-emitting area of ​​each sub-pixel can become larger. Thus, the light-emitting aperture ratio of the light-emitting panel can be increased, and light with sufficient brightness can be emitted.

[0142] According to an embodiment of the present invention, the contact hole 89 and / or the center contact hole 89c may overlap with the light-emitting area of ​​the light-emitting diode ED on the third-direction DR3, and the light-emitting layer 370 may cover the top of the contact hole 89 and / or the center contact hole 89c without being covered by the fifth insulating layer that serves as the pixel defining layer.

[0143] Next, a visual device including a light source device comprising a light-emitting panel will be described according to the above embodiments of the present invention.
