Description

[0001] This application claims priority to Korean Patent Application No. 10-2019-0076537, filed on June 26, 2019, and claims all rights arising therefrom, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] The display device may include a display panel, which includes pixels for displaying images. The display device may further include sensors for sensing the proximity of objects and ambient brightness, and these sensors may be located around the display panel. The display device may include sensors disposed in a bezel area (the area surrounding the screen), and objects may be identified by the sensors.

[0004] Reducing the bezel area of ​​a display device increases its screen-to-body ratio, which is the ratio of the screen to the front of the display. The screen-to-body ratio reflects the technological level of the display device and plays a significant role in consumer product selection. However, because it is difficult to place sensors within the bezel area when reducing its size, there is a need to develop technologies that allow sensors to be positioned and detected in narrow areas.

[0050] In the following, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0051] In the following text, reference will be made to Figures 1 to 4 A detailed description of an exemplary embodiment of the display device is provided.

[0052] Figure 1 , Figure 2 and Figure 3 These are plan views showing the display areas of a display device according to an exemplary embodiment, and Figure 4 This is a schematic cross-sectional view of a display device according to an exemplary embodiment.

[0053] refer to Figure 1 An exemplary embodiment of the display device 1000a may include a first display area DA1 and a second display area DA2, wherein the first display area DA1 is an area for displaying images, and the second display area DA2 can display images and has other functions.

[0054] In the plan view, the second display area DA2 can be surrounded by the first display area DA1, and the second display area DA2 can be disposed at the periphery of one side of the display device 1000a. In the plan view, the first display area DA1 can be disposed between the edge of the second display area DA2 and the edge of the display device 1000a. That is, referring to the second direction DR2, at least one pixel row including the first display area DA1 can be disposed above the pixel row disposed at the outermost edge of the second display area DA2.

[0055] In an exemplary embodiment, the second display area DA2 may be disposed at the periphery of the upper end of the display device 1000a, and may have a planar shape extending along a large portion of the upper edge of the display device 1000a in a first direction DR1.

[0056] In this embodiment, optical components may be disposed in the second display area DA2, and the optical components will be described below.

[0057] In an exemplary embodiment, the optical component may include an infrared sensor. The infrared sensor can receive light of infrared wavelengths and light reflected by an object. Display devices (e.g., Figure 1 1000a in Figure 2 1000b in Figure 3 1000c and Figure 4 The distance between the display device and the object is calculated based on the intensity of the reflected light (1000 in the equation), and if the distance is within a predetermined range, the image may not be displayed.

[0058] In an exemplary embodiment, the optical component may include an illuminance sensor. The illuminance sensor can measure the illuminance around the display device, and the display device can adjust the brightness of the screen based on the measured illuminance.

[0059] Alternatively, the display device may include optical components with various other functions, and is not limited to those described above.

[0060] In this embodiment, more light of a specific wavelength can be incident on or emitted from the second display area DA2 compared to the first display area DA1. In the second display area DA2, the proportion of the area where the displayed image is located, i.e., the area occupied by pixel regions, can be smaller than the proportion of the area occupied by pixel regions in the first display area DA1.

[0061] The resolution of the second display area DA2 can be lower than that of the first display area DA1. In this embodiment, the average number of pixels included in the second display area DA2 (i.e., the number of pixels per unit area) can be smaller than the average number of pixels included in the first display area DA1. However, since the pixel areas and the transmission areas are regularly alternately arranged in the second display area DA2, the image displayed in the second display area DA2 may not be degraded.

[0062] refer to Figure 2 In an alternative exemplary embodiment, the second display area DA2 and Figure 1 The second display area DA2 in the illustrated exemplary embodiment is substantially the same as the first display area DA1, except that the first display area DA1 may not be located around at least one side of the second display area DA2. In the plan view, one edge of the second display area DA2 may coincide with one edge of the display device 1000b. In an exemplary embodiment, for example, when the second display area DA2 is disposed at the periphery of the upper edge of the display device 1000b, the first display area DA1 may not be disposed above the second display area DA2. Referring to the second direction DR2, the outermost pixel row included in the second display area DA2 may be the outermost pixel row of the pixel area corresponding to the combination of the first display area DA1 and the second display area DA2.

[0063] refer to Figure 3 In another alternative exemplary embodiment, the second display area DA2 and Figure 2 The exemplary embodiments shown are substantially the same, except that the second display area DA2 is positioned adjacent to or outside the corner edge of the display device 1000c. In the plan view, one edge of the second display area DA2 may coincide with one corner edge of the display device 1000c. In one exemplary embodiment, for example, if the second display area DA2 is positioned outside the upper corner of the display device 1000c, one edge of the second display area DA2 may coincide with one corner edge on the upper side of the display device 1000c.

[0064] In this embodiment, the second display area DA2 can be located at various positions within the display area of ​​the display device and can have various planar shapes. In another alternative exemplary embodiment, although not shown, the second display area DA2 can have a circular planar shape located at the periphery of the upper edge of the display device.

[0065] refer to Figure 4An exemplary embodiment of the display panel 30 included in the display device 1000 may include a lower substrate 10 and an encapsulation substrate 20 disposed in the first display area DA1 and the second display area DA2. The lower substrate 10 may be continuously formed in the first display area DA1 and the second display area DA2, and there are no removed portions. A sealant 310 may be further disposed at the edge of the display panel 30 between the lower substrate 10 and the encapsulation substrate 20.

[0066] Multiple first pixel regions PA1 can be set in the first display area DA1. Multiple second pixel regions PA2 and multiple transmissive regions TA can be set in the second display area DA2. See later. Figure 5 The first pixel region PA1, the second pixel region PA2, and the transmission region TA are described in more detail.

[0067] In an exemplary embodiment, the display device 1000 may include a display panel 30 and an optical component 500 disposed behind the display panel 30, and the light of the wavelength used by the optical component 500 can pass through the second display area DA2 with a higher transmittance than that in the first display area DA1. The optical component 500 may include a camera, a flash, or a sensor, etc.

[0068] The optical component 500 emits light within a predetermined wavelength range toward an object 600 disposed near the display panel 30, or can receive light reflected from the object 600. This predetermined wavelength of light can be light of a wavelength that can be processed by the optical component 500, and can be light of a wavelength other than the visible light region, which is determined by the pixels PX (see...). Figure 10 The light used to display the image. Light of a predetermined wavelength can pass through the transmission region TA provided in the second display area DA2. In an exemplary embodiment, when the optical component 500 is an infrared camera, the light of the predetermined wavelength can be infrared light of approximately 900 nanometers (nm) to approximately 1000 nm.

[0069] In the plan view, the optical component 500 can be configured to correspond to the entire portion of the second display area DA2, or it can be configured to correspond only to a portion of the second display area DA2. In an exemplary embodiment, for example, as shown... Figure 4 As shown, the optical component 500 can be configured to correspond to a portion of the second display area DA2.

[0070] In the following text, reference will be made to Figures 5 to 9 The accompanying drawings describe in detail the first display area DA1 and the second display area DA2 of the display device 1000 according to an exemplary embodiment.

[0071] Figure 5The first and second display areas are schematically shown according to an exemplary embodiment. Figure 6 The diagram schematically shows the first pixel region, the second pixel region, and the transmission region. Figure 7 It is along Figure 6 The cross-sectional view taken from line VII-VII', and Figure 8 and Figure 9 The illustration schematically depicts a method for manufacturing a common electrode according to an exemplary embodiment.

[0072] In an exemplary embodiment, reference is made to Figure 5 The first display area DA1 includes multiple first pixel areas PA1, and the second display area DA2 includes multiple second pixel areas PA2 and multiple transmissive areas TA. A first pixel area PA1 and a second pixel area PA2 may have the same size or may have different sizes.

[0073] The second display area DA2 may include a second pixel area PA2 and a transmissive area TA, and the transmissive area TA may have a higher transmittance than the second pixel area PA2 relative to light of a specific wavelength (e.g., infrared wavelength). No pixels are disposed in the transmissive area TA, such that light from the image to be displayed may not be displayed or emitted from the transmissive area TA. Here, a pixel may be a unit area in which light from an image is emitted.

[0074] In the first display area DA1, a plurality of first pixel regions PA1 can be arranged in a matrix along different first directions DR1 and second directions DR2. In the second display area DA2, a plurality of second pixel regions PA2 and a plurality of transmissive regions TA can be arranged in a matrix. In an exemplary embodiment, for uniform distribution of the second pixel regions PA2 and transmissive regions TA, the second pixel regions PA2 and transmissive regions TA can be arranged in a checkerboard pattern. In this embodiment, a transmissive region TA is adjacent to a second pixel region PA2 on the periphery of the second pixel region PA2 along the first direction DR1 and the second direction DR2, and a second pixel region PA2 can be adjacent to a transmissive region TA on the periphery of the transmissive region TA along the first direction DR1 and the second direction DR2. A second pixel region PA2 and a transmissive region TA can have the same size or different sizes. Transmissive regions TA can have the same size or different sizes. The arrangement and size of the second pixel regions PA2 and transmissive regions TA can be modified in various ways.

[0075] In the second display area DA2, the transmission area TA and the second pixel area PA2 are arranged in a regular layout, so that images can be displayed as in the first display area DA1, and other functions such as infrared sensing and illuminance sensing, in addition to image display, can be performed by using the aforementioned optical component 500.

[0076] In an exemplary embodiment, reference is made to Figure 6 and Figure 7 Each of the first pixel region PA1 and the second pixel region PA2 may include a plurality of pixels R, G, and B. In an exemplary embodiment, the pixel has a configuration including a pixel circuit section and a pixel light-emitting section, and see reference [reference needed]. Figure 23 The described cross-section shows that the pixel circuit section may include multiple wires and multiple conductive layers disposed between the substrate 110 and the pixel electrode 191a, and the pixel light-emitting section may include the pixel electrode 191a and the emitting layer 370.

[0077] The first pixel region PA1 and the second pixel region PA2 may each include at least one of a first pixel R displaying a first color, a second pixel G displaying a second color, and a third pixel B displaying a third color. According to an exemplary embodiment, the first pixel region PA1 and the second pixel region PA2 may each include a first pixel R, a second pixel G, and a third pixel B. In this embodiment, the first pixel region PA1 and the second pixel region PA2 may each include at least two first pixels R, at least four second pixels G, and at least two third pixels B. Each transmissive region TA may have a size corresponding to eight pixels, but is not limited thereto.

[0078] Multiple pixels R, G, and B included in a pixel row of pixel regions PA1 and PA2 can be arranged repeatedly along the first direction DR1 in the order of third pixel B, second pixel G, first pixel R, and second pixel G, or in the order of first pixel R, second pixel G, third pixel B, and second pixel G. The invention is not limited thereto, and the layout of pixels R, G, and B included in a pixel row can be modified in various ways.

[0079] In an exemplary embodiment, each of the transmission regions TA may include a first transmission region TA1 and a second transmission region TA2. The second transmission region TA2 may have a shape that surrounds the first transmission region TA1 on a plane.

[0080] The first transmission region TA1 and the second transmission region TA2 may have different transmittances relative to light of a specific wavelength. In one exemplary embodiment, for example, the transmittance of the first transmission region TA1 may be greater than that of the second transmission region TA2. The common electrode 270 may not overlap with the first transmission region TA1 on a plane, and a portion of the common electrode 270 and a portion of the signal line may be disposed in the second transmission region TA2 such that the transmittance of the first transmission region TA1 is greater than that of the second transmission region TA2. In this embodiment where a portion of the common electrode 270 and a portion of the signal line may be disposed in the second transmission region TA2, the second transmission region TA2 may have a transmittance greater than that of each of the first pixel region PA1 and the second pixel region PA2, and may substantially transmit some light.

[0081] The first display area DA1 may include multiple first units A. First unit A may include multiple first pixel areas PA1 arranged in a 2×2 matrix. The second display area DA2 may include multiple second units B. Second unit B may have a second pixel area PA2 and a transmission area TA arranged in one row, and another transmission area TA and another second pixel area PA2 arranged in the next row.

[0082] In this embodiment, the common electrode 270 can be disposed in the first display area DA1 and the second display area DA2 of the display device 1000. The portion of the common electrode 270 overlapping with the first display area DA1 and the portion of the common electrode 270 overlapping with the second display area DA2 can be connected to define a single electrode or integral unit, thereby enabling the transmission of a constant common voltage.

[0083] The common electrode 270 located in the first display area DA1 can be continuously formed into a single electrode without cuts, openings, patterns, etc.

[0084] Multiple openings 275 are defined by the arrangement of a common electrode 270 in a portion of the second display area DA2. In a plan view, the multiple openings 275 may overlap with a portion of the transmission area TA (e.g., the first transmission area TA1).

[0085] In an exemplary embodiment, such as Figure 6 and Figure 7As shown, the common electrode 270 may include a first region R1 overlapping with the first pixel region PA1 and the second pixel region PA2, a second region R2 overlapping with the first transmission region TA1, and a third region R3 disposed between the first region R1 and the second region R2 and overlapping with the second transmission region TA2. The second region R2 may be a region overlapping with an opening 275 defined in the common electrode 270. The third region R3 may be disposed along the edge of the first transmission region TA1.

[0086] In the first region R1, the common electrode 270 may have a substantially constant predetermined thickness. In the second region R2, the common electrode 270 may have a partially removed shape, and the second region R2 may overlap with the opening 275 of the common electrode 270. In the third region R3, the common electrode 270 may have a thickness of approximately 10% to approximately 90% of its thickness in the first region R1.

[0087] In an exemplary embodiment, the common electrode 270 may have a planar shape that substantially corresponds to the first region R1 and the third region R3. In this embodiment, the first region R1 and the third region R3 may be connected to each other, and the first region R1, which is located in different rows or different columns, may be connected to each other through the third region R3.

[0088] In this embodiment, the opening 275 overlapping the first transmission region TA1 is defined by a common electrode 270, and therefore the common electrode 270 can have a shape that is partially removed in the first transmission region TA1. Therefore, the transmittance in the transmission region TA relative to light of a specific wavelength (e.g., infrared wavelength) can become greater than the transmittance in the first pixel region PA1 and the second pixel region PA2. Thus, light emitted from the optical member 500 disposed on the rear side of the display panel 30, or light incident on the optical member 500, is transmitted through the display panel 30 in the transmission region TA with high transmittance, and correspondingly, the recognition rate, sensing accuracy, etc., of the object 600 identified by the optical member 500 can be increased.

[0089] In this embodiment, the common electrode 270 can be partially removed in the area overlapping with the second display area DA2, and thus can have a reduced area compared to the area of ​​the common electrode 270 overlapping the entire second display area DA2. Therefore, the signal delay caused by resistor-capacitor (“RC”) delay can be reduced.

[0090] Next, we will refer to Figure 8 and Figure 9 Detailed description for manufacturing the above reference Figure 6 and Figure 7 An exemplary embodiment of the method for the described common electrode 270.

[0091] In an exemplary embodiment, such as Figure 8 As shown, a portion of the common electrode 270 is deposited on the substrate 110 using a mask (see Figure 110). Figure 23 In this embodiment, multiple openings OP are defined in a mask, and a portion of the common electrode 270 is formed in the region corresponding to the openings OP.

[0092] In this embodiment, the first region R1 of the common electrode 270 can be formed in the region corresponding to the opening OP, and the third region R3 of the common electrode 270 can be formed along the edge of each opening OP.

[0093] Next, as Figure 9 As shown, the same mask moves a predetermined distance in the first direction DR1 and a predetermined distance in the second direction DR2 to deposit a portion of the common electrode 270 on the substrate 110 again.

[0094] In this embodiment, as referenced above... Figure 8 As described, the first region R1 of the common electrode 270 can be formed in the region corresponding to the opening OP, and the third region R3 of the common electrode 270 can be formed along the edge of the opening OP.

[0095] The above reference Figure 7 The described common electrode 270 can be formed by repeating this process multiple times. In this process, a first region R1 of the common electrode 270 is formed in a region overlapping with the opening OP of the mask, a second region R2 of the common electrode 270 is formed in a region not overlapping with the opening OP, and a third region R3 can be formed between the first region R1 and the second region R2. The third region R3 can be an edge region surrounding the opening OP and can be a shaded region with a thickness of approximately 10% to 90% of the thickness of the common electrode 270 formed in the first region R1.

[0096] According to an exemplary embodiment, adjacent third regions R3 can overlap each other. Therefore, first regions R1 located in different rows or columns can also be connected to each other through third regions R3 and can receive the same voltage from each other.

[0097] Next, refer to Figure 10 An exemplary embodiment of the display device 1000 will be described below. Figure 10 The diagram schematically illustrates data lines and drive voltage lines disposed in the display area according to an exemplary embodiment.

Hereinafter, (n)-1 sub-columns, (n)-2 sub-columns, (n)-3 sub-columns, and (n)-4 sub-columns may refer to the first through fourth sub-columns of the nth column, respectively.

[0101] In sub-column (n)-1, data line 171 and driving voltage line 172 extend along the second transmission region TA2 located at the left edge of the transmission region TA and overlap with the second pixel region PA2 (not shown in the figure) on the left side, and can then be sequentially connected to the third pixel B and the first pixel R. In sub-column (n)-1, data line 171 and driving voltage line 172 can further pass through the second pixel region PA2 (not shown) located at the left edge of the transmission region TA, and can then be alternately connected to a plurality of third pixels B and a plurality of first pixels R included in the first pixel region PA1.

[0102] In the (n)-2 sub-column, data line 171 and driving voltage line 172 travel along a second transmission region TA2 located at the left edge of the transmission region TA, and then connect to two second pixels G, and can then travel along the second transmission region TA2 located at the left edge of the transmission region TA. Data line 171 and driving voltage line 172 can be further extended to connect to multiple second pixels G located in the (n)-2 sub-column of the first pixel region PA1.

[0103] In the (n)-3 sub-column, data line 171 and driving voltage line 172 travel along a second transmission region TA2 located at the right edge of the transmission region TA, and then connect with a first pixel R and a third pixel B, and can then travel along the second transmission region TA2 located at the right edge of the transmission region TA again. Data line 171 and driving voltage line 172 can be further extended to alternately connect with a plurality of first pixels R and a plurality of third pixels B located in the (n)-3 sub-column.

[0104] In the (n)-4 sub-column, data line 171 and drive voltage line 172 extend overlapping with the second pixel region PA2 located on the right side as they travel along the second transmission region TA2 located at the right edge of the transmission region TA, and then pass through the second pixel G and travel along the second transmission region TA2 located at the right edge of the transmission region TA and the second pixel region PA2 located on the right side.

[0105] In a plurality of second pixel regions PA2 located in the nth column, a plurality of pixels R, G, and B included in the second pixel region PA2 can be connected to a plurality of data lines 171 and a plurality of drive voltage lines 172. In this embodiment, at least a portion of the plurality of data lines 171 can be routed around the left region of the second transmission region TA2 overlapping, and another portion of the plurality of data lines 171 can be routed around the right region of the second transmission region TA2 overlapping.

[0107] When the data line 171 and driving voltage line 172 overlap with the second transmission region TA2, they can overlap with the third region R3 of the common electrode 270. In this embodiment, the data line 171 and driving voltage line 172 that overlap with the second pixel region PA2 can overlap with the first region R1 of the common electrode 270 when they overlap. The data line 171 and driving voltage line 172 can overlap with either the second transmission region TA2 or the second pixel region PA2.

[0108] The following describes the multiple data lines 171 and multiple drive voltage lines 172 included in the (n+1)th column. The multiple second pixel regions PA2 and multiple first pixel regions PA1 located in the (n+1)th column may include multiple pixels R, G, and B corresponding to the (n+1)-1 sub-column, (n+1)-2 sub-column, (n+1)-3 sub-column, and (n+1)-4 sub-column. Here, the (n+1)-1 sub-column, (n+1)-2 sub-column, (n+1)-3 sub-column, and (n+1)-4 sub-column may refer to the first to fourth sub-columns of the (n+1)th column.

[0109] In the (n+1)-1 sub-column, data line 171 and driving voltage line 172 can be connected to the third pixel B and the first pixel R located in the (n+1)-1 sub-column, and then reconnected to the third pixel B and the first pixel R after passing through the second pixel region PA2 adjacent to the second transmission region TA2. Data line 171 and driving voltage line 172 can be further extended to alternately connect to multiple third pixels B and multiple first pixels R located in the (n+1)-1 sub-column of the first pixel region PA1.

[0110] In the (n+1)-2 sub-column, data line 171 and driving voltage line 172 can be connected to two second pixels G, and then can be connected to two second pixels G again after overlapping with the second transmission region TA2 in the left region of the transmission region TA. Data line 171 and driving voltage line 172 can be further extended to connect to multiple second pixels G located in the (n+1)-2 sub-column in the first pixel region PA1.

[0111] In the (n+1)-3 sub-column, data line 171 and driving voltage line 172 pass through the first pixel R and the third pixel B, and can then be connected to the first pixel R and the third pixel B after overlapping with the right region of the second transmission region TA2. Data line 171 and driving voltage line 172 can be further extended to alternately connect to multiple first pixels R and multiple third pixels B located in the (n+1)-3 sub-column of the first pixel region PA1.

[0112] Next, in the (n+1)-4 sub-column, data line 171 and driving voltage line 172, after passing through the second pixel G, overlap with the second pixel region PA2 (not shown) to the right of the second transmission region TA2, and can then be reconnected to the second pixel G. Data line 171 and driving voltage line 172 can be further extended to connect to multiple second pixels G located in the (n+1)-4 sub-column of the first pixel region PA1.

[0113] In the second pixel region PA2 located in each column, a plurality of pixels R, G, and B included in the second pixel region PA2 can be connected to a plurality of data lines 171 and a plurality of drive voltage lines 172. In this embodiment, at least a portion of the plurality of data lines 171 can overlap with the left region of the second transmission region TA2, and another portion of the plurality of data lines 171 can overlap with the right region of the second transmission region TA2. In this embodiment, a portion of the remaining portion of the plurality of data lines 171 can overlap with the adjacent second pixel region PA2.

[0114] In an exemplary embodiment, at least a portion of the plurality of driving voltage lines 172 may overlap with the left region of the second transmission region TA2, and another portion of the plurality of driving voltage lines 172 may overlap with the right region of the second transmission region TA2. In this embodiment, a portion of the remaining portion of the plurality of driving voltage lines 172 may overlap with the adjacent second pixel region PA2.

[0115] The data line 171 and driving voltage line 172, which travel along the second transmission region TA2, can overlap with the third region R3 of the common electrode 270. In this embodiment, the data line 171 and driving voltage line 172, which travel along the second pixel region PA2, can overlap with the first region R1 of the common electrode 270. That is, the data line 171 and driving voltage line 172 can overlap with either the second transmission region TA2 or the second pixel region PA2.

[0116] Data lines 171 and driving voltage lines 172 connected to multiple pixels R, G, and B can overlap with the first region R1 and / or the third region R3 of the common electrode 270. Specifically, data lines 171 and driving voltage lines 172 overlapping with the first pixel region PA1 and the second pixel region PA2 can overlap with the first region R1 of the common electrode 270. Data lines 171 and driving voltage lines 172 overlapping with the second transmission region TA2 can overlap with the third region R3 of the common electrode 270. In this embodiment, data lines 171 and driving voltage lines 172 that travel along the edge of the first transmission region TA1 can overlap with the third region R3 of the common electrode 270. Data lines 171 and driving voltage lines 172 overlapping with the second transmission region TA2 can alternately overlap with the first region R1 and the third region R3 of the common electrode 270. Therefore, the area occupied by signal lines in the transmission region TA can be reduced, thereby increasing the transmittance of the transmission region TA where the optical component 500 is located.

[0117] Next, an exemplary embodiment of the display device 1000 will be described. Figure 11 The diagram schematically illustrates scan lines and light emission control lines located in the display area according to an exemplary embodiment.

[0118] In the second pixel region PA2 and the transmission region TA corresponding to the nth row, the second pixel region PA2 and the transmission region TA can be alternately set from the left along the first direction DR1. In the (n+1)th row, the transmission region TA and the second pixel region PA2 can be alternately set from the left along the first direction DR1.

[0119] The second pixel region PA2 located in the nth row can, for example, include multiple pixels R, G, and B arranged in two rows. The multiple pixels R, G, and B located in the (n)-1 sub-row can be the third pixel B, the second pixel G, the first pixel R, and the second pixel G along the first direction DR1. Here, the (n)-1 sub-row and the (n)-2 sub-row can refer to the first and second sub-rows of the nth row, respectively. The multiple pixels R, G, and B located in the (n)-2 sub-row can be the first pixel R, the second pixel G, the third pixel B, and the second pixel G along the first direction DR1. However, the arrangement of pixels R, G, and B is not limited to this and can be modified in various ways.

In the second pixel region PA2 located in the nth row, at least a portion of the remaining portion of the light emission control line 153 connected to the plurality of pixels B, G, R, and G located in the (n)-1 sub-row and the plurality of scan lines 151, 152, and 154 can be routed along the second pixel region PA2 (not shown) located above the second transmission region TA2, and then reconnected to the plurality of pixels B, G, R, and G included in the second pixel region PA2.

In the second pixel region PA2 located in the nth row, a portion of the remaining portion of the light emission control line 153 connected to the plurality of pixels R, G, B, and G located in the (n)-2 sub-rows, and the plurality of scan lines 151, 152, and 154, can be routed along the second pixel region PA2 located below the second transmission region TA2, and then reconnected to the plurality of pixels R, G, B, and G included in the second pixel region PA2.

[0123] At least a portion of the light emission control line 153 connected to the plurality of pixels B, G, R, and G located in the (n+1)-1 sub-row and the plurality of scan lines 151, 152, and 154 may be routed along the second pixel region PA2 located above the second transmission region TA2, and then connected to the plurality of pixels B, G, R, and G included in the second pixel region PA2, and then routed along the second pixel region PA2 again above the second transmission region TA2. A portion of the remaining portion of the light emission control line 153 connected to the plurality of pixels B, G, R, and G and the plurality of scan lines 151, 152, and 154 may be routed along the second transmission region TA2 to connect to the plurality of pixels B, G, R, and G included in the second pixel region PA2, and then routed along the second transmission region TA2 again. At least a portion of the light emission control lines 153 and the multiple scan lines 151, 152, and 154 connected to the plurality of pixels R, G, B, and G disposed in the (n+1)-2 sub-rows can be connected to the plurality of pixels R, G, B, and G included in the second pixel region PA2 by means of a route around the lower region of the second transmission region TA2, and then can be routed around the lower region of the second transmission region TA2. Here, the (n+1)-1 sub-row and the (n+1)-2 sub-row can refer to the first sub-row and the second sub-row of the (n+1)-1 row. A portion of the remaining portion of the light emission control lines 153 and the multiple scan lines 151, 152, and 154 connected to the plurality of pixels R, G, B, and G disposed in the (n+1)-2 sub-rows can be connected to the plurality of pixels R, G, B, and G included in the second pixel region PA2 disposed below the second transmission region TA2 by means of a route around the second pixel region PA2 (not shown), and then can be routed around the second pixel region PA2 (not shown) disposed below the second transmission region TA2.

[0124] The light-emitting control line 153 extending along the first direction DR1, along with multiple scan lines 151, 152, and 154, may intersect the second pixel region PA2 and may overlap with the first region R of the common electrode 270 that overlaps with the second pixel region PA2. In this embodiment, at least a portion of the light-emitting control line 153 and the multiple scan lines 151, 152, and 154 may overlap with the third region R3 of the common electrode 270. At least a portion of the light-emitting control line 153 and the multiple scan lines 151, 152, and 154 may alternately overlap with the first region R1 and the third region R3 of the common electrode 270. This shape allows the first transmission region TA1, which has relatively high transmittance, to be enlarged or maximized, thereby providing a transmission region TA with improved light transmittance.

[0125] In the following text, reference will be made to Figures 12 to 14 The exemplary embodiments described above will be described in more detail.

[0126] Figure 12 This schematically illustrates multiple second pixel regions corresponding to the nth row and multiple second pixel regions PA2 corresponding to the (n+1)th row. Figure 13 schematically shown Figure 12 The common electrode of the exemplary embodiment, and Figure 14 Show Figure 13 Exemplary modifications.

[0127] First, refer to Figure 12 The two second pixel regions PA2 and the two transmissive regions TA can be arranged in a checkerboard pattern. In the nth row, the second pixel region PA2 and the transmissive region TA can be arranged in this order, and in the (n+1)th row, the transmissive region TA and the second pixel region PA2 can be arranged in this order.

[0128] In an exemplary embodiment, each second pixel region PA2 may include, for example, eight pixels PX. In this embodiment, each pixel PX may include multiple data lines 171 and multiple drive voltage lines 172 extending along the second direction DR2.

[0129] Data lines 171 and driving voltage lines 172, which connect to the four pixels PX on the left side of the eight pixels PX arranged in the nth row and nth column, can extend along the left side of the second transmission region TA2 arranged in the nth column and n+1th row. In this embodiment, at least a portion of the data lines 171 and driving voltage lines 172 can extend overlapping the transmission region TA, and a portion of the remaining portions of the data lines 171 and driving voltage lines 172 can extend overlapping the second transmission region TA2 and the adjacent second pixel region PA2 (not shown).

[0130] The data line 171 and driving voltage line 172, which connect to the four pixels PX on the right side of the eight pixels PX arranged in the nth row and nth column, can bypass the right region of the second transmission region TA2 arranged in the nth column and n+1th row. In this embodiment, at least a portion of the data line 171 and driving voltage line 172 can extend overlapping the transmission region TA, and a portion of the remaining portion of the data line 171 and driving voltage line 172 can extend overlapping the transmission region TA and the adjacent second pixel region PA2.

[0131] Data line 171 extending along the left edge of the transmission region TA and / or the second pixel region PA2 in the nth row and n+1th column can be connected to two pixels PX that are positioned opposite each other on the left side of the eight pixels PX in the n+1th row and n+1th column. Driving voltage line 172 extending along the left edge of the transmission region TA and / or the second pixel region PA2 in the nth row and n+1th column can be connected to two pixels PX that are positioned opposite each other on the left side of the eight pixels PX in the n+1th row and n+1th column.

[0132] In an exemplary embodiment, at least a portion of the scan lines 151, 152, and 154, which connect to the four pixels PX disposed on the upper side of the eight pixels PX in the nth row and nth column, and the light emission control line 153, may extend along the upper region of the second transmission region TA2 disposed in the nth row and n+1th column. A portion of the remaining portions of the scan lines 151, 152, and 154, which connect to the four pixels PX disposed on the upper side of the eight pixels PX in the nth row and nth column, and the light emission control line 153, may extend along the transmission region TA disposed in the nth row and n+1th column and the second pixel region PA2 (not shown) disposed above it.

[0133] At least a portion of the scan lines 151, 152, and 154, which connect to the four lower pixels of the eight pixels PX arranged in the nth row and nth column, and the light emission control line 153, can extend along the lower region of the transmissive region TA arranged in the nth row and n+1th column. In this embodiment, a portion of the remaining portion of the scan lines 151, 152, and 154, which connect to the four lower pixels of the eight pixels PX arranged in the nth row and nth column, and the light emission control line 153, can extend along the transmissive region TA arranged in the nth row and n+1th column and the second pixel region PA2 disposed below it.

[0134] In an exemplary embodiment, at least a portion of the signal lines that are not connected to any pixel and travel along the transmission region TA may overlap with the transmission region TA (e.g., the second transmission region TA2), and other portions may travel in an overlapping manner with the adjacent second pixel region PA2. Alternatively, all of the multiple traveling signal lines may travel in an overlapping manner with the transmission region TA (specifically, the second transmission region TA2).

[0135] In an exemplary embodiment, as described above, each pixel region PA1 or PA2 may include eight pixels PX, but is not limited thereto. In this embodiment, the number of pixels PX can be modified or appropriately adjusted in various ways. In an exemplary embodiment, data lines 171 and driving voltage lines 172 are arranged symmetrically in pixel regions PA1 or PA2 and transmission regions TA, but are not limited thereto. Alternatively, data lines 171 and driving voltage lines 172 may be arranged asymmetrically with respect to each other.

[0136] Figure 13 Showing with Figure 12 An exemplary embodiment of the common electrode is combined. See also Figure 13 In an exemplary embodiment, the light emission control line 153, multiple data lines 171, multiple drive voltage lines 172, and multiple scan lines 151, 152, and 154 overlapping with the second pixel region PA2 can overlap with the first region R1 of the common electrode 270. In this embodiment, the light emission control line 153, multiple data lines 171, multiple drive voltage lines 172, and multiple scan lines 151, 152, and 154 extending along the second transmission region TA2 can overlap with the third region R3 of the common electrode 270. The first transmission region TA1 can overlap with the second region R2 corresponding to the opening of the common electrode 270, and the transmittance relative to a specific wavelength can be improved. In this embodiment, since the signal lines passing through the second transmission region TA2 are arranged along the edge of the first transmission region TA1, the area of ​​the first transmission region TA1 can be effectively increased or maximized.

[0137] In an exemplary embodiment, as described above, the edges of the first region R1, the second region R2, and the third region R3 of the common electrode 270 are formed in a straight-line shape. Alternatively, as... Figure 14 As shown, the common electrode 270 may have rounded edges. The first region R1 and the third region R3 of the common electrode 270 may have a circular shape, but are not limited thereto. The first region R1 and the third region R3 of the common electrode 270 may be modified in various ways.

[0138] In the following text, reference will be made to Figures 15 to 20 The planar shape of a pixel light-emitting portion according to an exemplary embodiment is described. In an exemplary embodiment, the first pixel region PA1 and the second pixel region PA2 may include at least one or more pixel light-emitting portions, which will be referenced to...

In the following description, for ease of description, the reference numerals "R", "G", and "B" are also used to refer to the pixel light-emitting section.

[0139] In an exemplary embodiment, reference is made to Figure 15 The pixel light-emitting parts R, G and B included in each pixel unit PUa can have the same shape as each other, for example, an approximately rectangular shape, and can be arranged in one direction.

[0140] See Figure 16 In an alternative exemplary embodiment, each of the pixel light-emitting portions R, G, and B included in each pixel unit PUb may have a basic rectangular shape. Two of the three pixel light-emitting portions R, G, and B, such as the red pixel light-emitting portion R and the green pixel light-emitting portion G, may be perpendicularly adjacent to each other, and the remaining one of the three pixel light-emitting portions, the blue pixel light-emitting portion B, may be disposed on one side of each of the red pixel light-emitting portion R and the green pixel light-emitting portion G, while extending in the vertical direction. The red pixel light-emitting portion R and the green pixel light-emitting portion G may be arranged in the horizontal direction.

[0141] See Figure 17 In another alternative exemplary embodiment, the pixel light-emitting portions R, G, and B included in each pixel unit PUc may have an approximately rhomboid shape. The red pixel light-emitting portion R, the green pixel light-emitting portion G, and the blue pixel light-emitting portion B may differ in size from each other. In one exemplary embodiment, for example, the blue pixel light-emitting portion B may be the largest, while the green pixel light-emitting portion G may be the smallest.

[0142] Alternatively, such as Figure 18 As shown, each pixel unit PUd may include a red pixel light-emitting part R, a blue pixel light-emitting part B, and two green pixel light-emitting parts G. Each of the pixel light-emitting parts R, G, and B included in each pixel unit PUd may have an approximately rhomboid shape. The red pixel light-emitting part R, the green pixel light-emitting part G, and the blue pixel light-emitting part B may differ in size from each other. In an exemplary embodiment, for example, the blue pixel light-emitting part B may be the largest, while the green pixel light-emitting part G may be the smallest.

[0143] Figure 19 and Figure 20 The exemplary embodiments shown are consistent with those referenced above. Figure 17 and Figure 18The exemplary embodiments described are substantially the same, except that the positions of the red pixel light-emitting part R and the blue pixel light-emitting part B included in the pixel units PUe and PUf can be different. Figure 17 and Figure 18 In the pixel units PUc and PUd shown, the positions of the red pixel light-emitting part R and the blue pixel light-emitting part B are opposite.

[0144] In the following text, reference will be made to Figures 21 to 23 The detailed description includes a pixel in either the first display area DA1 or the second display area DA2.

[0145] Figure 21 This is a circuit diagram of the pixels of a display device according to an exemplary embodiment. Figure 22 This is a top view of a plurality of pixels included in a display device according to an exemplary embodiment, and Figure 23 It is along Figure 22 A cross-sectional view taken from the line Va-Vb.

[0146] refer to Figure 21 An exemplary embodiment of the pixel PX may include a capacitor Cst, a light-emitting diode ED, and transistors T1, T2, T3, T4, T5, T6, and T7 connected to signal lines 151, 152, 153, 154, 161, 171, and 172.

[0148] 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 the gate on / off voltages of transistors T2, T3, T4, and T7 in pixel PX.

[0149] Scan lines 151, 152, and 154 connected to pixel PX 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. In one exemplary embodiment, for example, the scan signal GWn is the nth scan signal among scan signals applied during a frame, the scan signal GIn may be a previous scan signal like the (n-1)th scan signal, and the scan signal GI(n+1) may be the nth scan signal. The scan signal GI(n+1) may be a scan signal different from the nth scan signal.

[0150] The light emission control line 153 can transmit a light emission control signal EM to control the light emission of the light-emitting diode ED. The light emission control signal EM may include the gate on voltage and the gate off voltage.

[0151] Data line 171 can transmit a data signal Dm. Drive voltage line 172 can transmit a drive voltage ELVDD. The data signal Dm can have a voltage level that varies based on the image signal input to the display device 1000, and the drive voltage ELVDD can have a substantially constant voltage. Initialization voltage line 161 can transmit a constant voltage such as an initialization voltage Vint.

[0152] The display device 1000 may include a driving device (e.g., a scan driver, a light-emitting driver, a data driver, and a signal controller, etc.) that generates signals transmitted to signal lines 151, 152, 153, 154, 161, 171, and 172.

[0153] The transistors T1, T2, T3, T4, T5, T6 and T7 included in the pixel PX may include a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a fifth transistor T5, a sixth transistor T6 and a seventh transistor T7.

[0154] The first scan line 151 can transmit the scan signal GWn to the second transistor T2 and the third transistor T3. The second scan line 152 can transmit the scan signal GIn to the fourth transistor T4. The third scan line 154 can transmit the scan signal GI(n+1) to the seventh transistor T7. The light emission control line 153 can transmit the light emission control signal EM to the fifth transistor T5 and the sixth transistor T6. Transistors T1, T2, T3, T4, T5, T6 and T7 can respectively include source electrodes S1, S2, S3, S4, S5, S6 and S7, drain electrodes D1, D2, D3, D4, D5, D6 and D7, and gate electrodes G1, G2, G3, G4, G5, G6 and G7.

[0155] The first transistor T1 can receive the data signal Dm transmitted through the data line 171 in response to the switching operation of the second transistor T2 and supply the drive current Id to the light-emitting diode ED.

[0156] The second transistor T2 is turned on by the scan signal GWn transmitted through the first scan line 151, and thus the data signal Dm transmitted from the data line 171 can be transmitted to the source electrode S1 of the first transistor T1.

[0157] The third transistor T3 is turned on by the scan signal GWn transmitted through the first scan line 151, and the first transistor T1 diode can be connected by connecting the gate electrode G1 and the drain electrode D1 of the first transistor T1.

[0158] The fourth transistor T4 is turned on in response to the scan signal GIn transmitted through the second scan line 152, and transmits the initialization voltage Vint to the gate electrode G1 of the first transistor T1, so that an initialization operation for initializing the voltage of the gate electrode G1 of the first transistor T1 can be performed.

[0159] The fifth transistor T5 and the sixth transistor T6 are simultaneously turned on in response to the light emission control signal EM transmitted through the light emission control line 153, and thus the drive voltage ELVDD is compensated through the diode-connected first transistor T1 and then transmitted to the light emission diode ED.

[0160] Transistors T1, T2, T3, T4, T5, T6 and T7 can be P-channel transistors, such as p-channel metal-oxide-semiconductor (“PMOS”) transistors, and at least one of transistors T1, T2, T3, T4, T5, T6 and T7 can be an N-channel transistor.

[0161] One end of capacitor Cst can be connected to the gate electrode G1 of the first transistor T1, and the other end can be connected to the drive voltage line 172. The cathode of the light-emitting diode ED can be connected to the common voltage terminal for transmitting the common voltage ELVSS, and therefore can receive the common voltage ELVSS.

[0162] The number of transistors and capacitors in a pixel PX, as well as their interconnections, can be modified in various ways.

[0163] The operation of the display device 1000 according to an exemplary embodiment will now be briefly described. When a scan signal GIn (which may be the (n-1)th scan signal) of a gate conduction voltage level is supplied through the second scan line 152 during the initialization period, the fourth transistor T4 is turned on, the initialization voltage Vint is transmitted through the fourth transistor T4 to the gate electrode G1 of the first transistor T1, and the first transistor T1 is initialized by the initialization voltage Vint.

[0164] Next, when a scan signal GWn (which may be the nth scan signal) of the gate conduction voltage level is supplied through the first scan line 151 during the data programming and compensation period, the second transistor T2 and the third transistor T3 are turned on. The first transistor T1 is connected to the diode of the turned-on third transistor T3 and is forward biased. Then, a compensated voltage, which has been reduced by approximately the threshold voltage of the first transistor T1 from the data signal Dm supplied through data line 171, is applied to the gate electrode G1 of the first transistor T1. The driving voltage ELVDD and the compensated voltage are applied to the opposite terminals of the capacitor Cst, respectively, and the charge corresponding to the voltage difference between the opposite terminals of the capacitor Cst can be stored in the capacitor Cst.

[0165] Next, when the light emission control signal EM supplied from the light emission control line 153 changes from the gate cutoff voltage level to the gate turn-on voltage level during the light emission period, the fifth transistor T5 and the sixth transistor T6 turn on, generating a drive current Id corresponding to the voltage difference between the gate voltage of the gate electrode G1 of the first transistor T1 and the drive voltage ELVDD. The drive current Id is supplied to the light emission diode ED through the sixth transistor T6, so that the current Ied flows to the light emission diode ED.

[0166] In this embodiment, during the initialization period, the seventh transistor T7 receives the scan signal GI(n+1) of the gate on-voltage level and is therefore turned on. The scan signal GI(n+1) can be the nth scan signal. Some of the drive current Id can be drawn out as a bypass current Ibp through the turned-on seventh transistor T7.

[0167] Next, we will refer to Figure 22 and Figure 23 The structure of the display device 1000 according to an exemplary embodiment will be described in detail.

[0170] Multiple scan lines 151, 152, and 154 can transmit scan signals.
