However, this disclosure is not limited to organic light-emitting display devices.

[0058] Reference will now be made in detail to aspects of this disclosure, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same or similar parts.

[0059] Figure 1 The diagram illustrates a schematic block diagram of a display device according to the present disclosure. Figure 2 The diagram illustrates a schematic block diagram of a subpixel in a display device according to the present disclosure.

[0060] Reference Figure 1 The display device 100 may include an image processor 102, a timing controller 104, a gate driver 106, a data driver 107, a power supply 108, and a display panel 109.

[0061] The image processor 102 outputs drive signals for driving various components, as well as image data supplied from the outside. For example, the drive signals output from the image processor 102 may include, but are not limited to, data enable signals, vertical synchronization signals, horizontal synchronization signals, clock signals, etc.

[0062] The timing controller 104 receives drive signals and image data from the image processor 102. Based on the drive signals input from the image processor 102, the timing controller 104 generates and outputs a gate timing control signal GDC for controlling the operating timing of the gate driver 106 and a data timing control signal DDC for controlling the operating timing of the data driver 107.

[0063] Gate driver 106 outputs a scan signal to display panel 109 in response to a gate timing control signal GDC supplied from timing controller 104. Gate driver 106 outputs the scan signal through multiple gate lines GL1 to GLm (m is an integer equal to or greater than 2). In one embodiment, gate driver 106 may be formed as an integrated circuit (IC), but is not limited thereto. In another embodiment, gate driver 106 may include various gate driving circuits formed directly on display panel 109. In this case, gate driver 106 may be a GIP (gate in panel).

[0064] Data driver 107 outputs a data voltage to display panel 109 in response to a data timing control signal DDC input from timing controller 104. Data driver 107 samples and latches a digital data signal DATA supplied from timing controller 104, and converts the digital data signal DATA into an analog data voltage based on gamma voltage. Data driver 107 outputs the data voltage through multiple data lines DL1 to DLn (n is an integer equal to or greater than 2). In one embodiment, data driver 107 may be formed as an integrated circuit (IC), but is not limited thereto.

[0065] Power supply 108 outputs a high-level voltage and a low-level voltage, and supplies these voltages to display panel 109. The high-level voltage is supplied to display panel 109 via a first power line EVDD, and the low-level voltage is supplied to display panel 109 via a second power line EVSS. Alternatively or additionally, the voltage output from power supply 108 can be output to gate driver 106 and / or data driver 107 to drive those drivers 106 and 107.

[0066] The display panel 109 displays an image in response to a scan signal supplied from the gate driver 106, a data voltage supplied from the data driver 107, and power supplied from the power supply 108.

[0067] Display panel 109 includes a plurality of subpixels SP for displaying images. In one embodiment, subpixels SP may include red (R) subpixels, green (G) subpixels, and blue (B) subpixels. Alternatively, subpixels SP may include white (W) subpixels, red (R) subpixels, green (G) subpixels, and blue (B) subpixels. In one embodiment, the white (W) subpixels, red (R) subpixels, green (G) subpixels, and blue (B) subpixels may have substantially the same area. Alternatively, the white (W) subpixels, red (R) subpixels, green (G) subpixels, and blue (B) subpixels may have different areas.

[0068] Reference Figure 2 Each sub-pixel SP can be connected to a gate line GL1, a data line DL1, a first power line EVDD, and a second power line EVSS. The number of transistors and capacitors and the driving method can be determined by the configuration of the pixel circuitry in the sub-pixel SP. For example, a sub-pixel SP may include two transistors and one capacitor (2T1C), but is not limited thereto. In another embodiment, the sub-pixel SP may include 3T1C, 4T1C, 5T1C, 6T1C, 7T1C, 3T2C, 4T2C, 5T2C, 6T2C, 8T2C, etc.

[0069] Figure 3 The diagram illustrates a schematic circuit diagram of a sub-pixel in a display device according to the present disclosure.

[0070] Reference Figure 3 The display device 100 includes gate lines GL, data lines DL, and power lines PL that intersect each other to define sub-pixels SP. Switching thin-film transistors Ts, driving thin-film transistors Td, storage capacitors Cst, and light-emitting diodes D can be disposed in the sub-pixels SP.

[0071] The switching thin-film transistor Ts is connected to the gate line GL and the data line DL. The driving thin-film transistor Td and the storage capacitor Cst are connected between the switching thin-film transistor Ts and the power line PL, and the light-emitting diode D is connected to the driving thin-film transistor Td.

[0072] In the display device 100, when the switching thin-film transistor Ts is turned on by the gate signal applied to the gate line GL, the data signal applied to the data line DL is applied to the gate electrode 114 through the switching thin-film transistor Ts. Figure 6A ) and one electrode of the storage capacitor Cst.

[0073] The driving thin-film transistor Td is turned on by a data signal applied to its gate electrode 114, such that a current proportional to the data signal is supplied from the power line PL through the driving thin-film transistor Td to the light-emitting diode D. The light-emitting diode D then emits light with a brightness proportional to the current flowing through the driving thin-film transistor Td. In this case, the storage capacitor Cst is charged to a voltage proportional to the data signal, such that the voltage at the gate electrode 114 in the driving thin-film transistor Td remains constant during one frame. Therefore, the display device 100 can display the desired image.

[0074] exist Figure 3 In the present invention, the display device 100 includes two thin-film transistors Ts and Td, and a storage capacitor Cst in the sub-pixel SD. However, the display device 100 may include three or more thin-film transistors and two or more storage capacitors in the sub-pixel SP.

[0075] Figure 4 The diagram illustrates a schematic plan view of a display device according to one embodiment of the present disclosure. Figure 5 The diagram illustrates the arrangement of lines in the display area of ​​a display device according to one embodiment of the present disclosure.

[0076] In one embodiment, the display device 100 may be applied to a free-form display device, but is not limited thereto. As used herein, a free-form display device may refer to a display device having a non-rectangular shape. For example, a free-form display device may be a non-rectangular display device such as a circle, ellipse, curved shape, or irregular shape, but is not limited thereto.

[0077] In one exemplary embodiment, the display device 100 can be a free-form display device applicable to various electronic devices such as watches and / or dashboards in vehicles. Hereinafter, a display device 100 having a circular shape will be described in more detail. In another embodiment, the display device 100 can be applied to a display device with rounded corners.

[0078] Reference Figure 4 and Figure 5 According to one embodiment, the display device includes a display area AA for displaying a real image and a non-display area NA (i.e., a first non-display area NA2 or a second non-display area NA2) disposed outside the display area AA.

[0079] Multiple gate lines GL1 to GLm and multiple data lines DL1 to DLn are arranged in the display area AA to define multiple sub-pixels SP1, SP2, and SP3. In one embodiment, sub-pixels SP1, SP2, and SP3 may include red (R) sub-pixels, green (G) sub-pixels, and blue (B) sub-pixels. Alternatively or additionally, sub-pixels SP may further include white (W) sub-pixels. In one embodiment, sub-pixels SP1, SP2, and SP3 may form a pixel P.

[0080] Thin-film transistors with switching elements and display elements for realizing a real image are set in each sub-pixel SP1, SP2 or SP3.

[0081] Display elements may include a variety of display elements. For example, display elements may include, but are not limited to, organic light-emitting elements, liquid crystal display elements, quantum dot display elements, micro LED (light-emitting diode) display elements, and mini LED display elements.

[0082] The display area AA can be divided into a first area A1, a second area A2, and a third area A3 along a first direction (horizontal direction, x-axis direction). Furthermore, since the areas on both sides of the first area are referred to as the second area, the second area A2 can be called the left second area and the third area A3 can be called the right second area.

[0083] In the first region A1 of the display area AA, multiple first data lines DL1 and multiple vertical connecting lines VLINK are arranged along a second direction (vertical direction, y-axis direction). In this case, one first data line DL1 and one vertical connecting line VLINK correspond to a sub-pixel column arranged along the second direction. Each of the multiple sub-pixels arranged in a sub-pixel column is electrically connected to the corresponding first data line DL1 to receive a data signal. In this case, the corresponding vertical connecting line VLINK is not electrically connected to the multiple sub-pixels arranged in the sub-pixel column.

[0084] Display areas A2 and A3 are arranged on both sides of the first area A1. Multiple second data lines DL2 and multiple third data lines DL3 extending along a second direction (vertical direction, y-axis direction) are arranged in the second area A2 and the third area A3, respectively. No vertical connecting lines VLINK are arranged in the second area A2 and the third area A3.

[0085] Multiple first data lines DL1 arranged in the first region A1 are formed to have the same length from the bottom to the top of the circular display area AA. The length of the second data line DL2 arranged in the second region A2 decreases from the central region outwards, that is, from the boundary of the first region A1 to the left end. Furthermore, the length of the third data line DL3 arranged in the third region A3 decreases from the central region outwards, that is, from the boundary of the first region A1 to the right end.

[0086] Multiple horizontal connecting lines HLINK are arranged along the first direction (x-axis direction) in the first area A1, the second area A2, and the third area A3 of the display area AA. The multiple horizontal connecting lines HLINK can be spaced apart from each other with the same spacing, but are not limited to this.

[0087] Each horizontal HLINK is electrically connected to a corresponding vertical VLINK in the first region A1 via the first contact hole CNT1. Each horizontal HLINK is provided with an insulating layer between it and the second data line DL2 in the second region A2 and the third data line DL3 in the third region A3, and is electrically connected via the second contact hole CNT2.

[0088] exist Figure 4 In one embodiment, multiple vertical VLINK lines and multiple horizontal HLINK lines are arranged on one side of sub-pixels SP1, SP2, and SP3. In another embodiment, the multiple vertical VLINK lines and multiple horizontal HLINK lines may be arranged across sub-pixels SP1, SP2, and SP3.

[0089] The leftmost vertical connection VLINK in the first region A1 can be electrically connected via the horizontal connection HLINK to the closest second data line DL2 arranged in the second region A2, that is, the rightmost second data line DL2 in the second region A2. Furthermore, the second vertical connection VLINK located from the leftmost side of the first region A1 can be electrically connected via the horizontal connection HLINK to the second second data line DL2 located from the rightmost side of the second region A2, but this is not a limitation.

[0090] The rightmost vertical line VLINK in the first region A1 can be electrically connected via the horizontal line HLINK to the nearest third data line DL3 in the third region A3, that is, the leftmost third data line DL3 in the third region A3. Furthermore, the second vertical line VLINK from the rightmost position in the first region A1 can be electrically connected via the horizontal line HLINK to the second third data line DL3 from the leftmost position in the third region A3, but this is not a limitation.

[0091] A gate driver 106 for applying various signals to sub-pixels SP1, SP2, and SP3 can be disposed in a first non-display area NA1 surrounding the display area AA. Figure 1 Gate driver 106 is connected to gate line GL1 through gate line GLm. Figure 1 The scan signal is applied to sub-pixels SP1, SP2, and SP3. In one embodiment, the gate driver 106 may be a gate driving circuit directly disposed on the substrate 140. Figure 6A and Figure 6B GIP circuitry on ).

[0092] A curved region BA extending from the first non-display region NA1 can be formed on the lower end of the first non-display region NA1. The curved region BA can be bent by bending in a certain direction. The second non-display region NA2 is the region extending from the curved region BA. A flexible circuit film (FPC) is attached to the second non-display region NA2.

[0093] Since the flexible circuit film FPC is disposed on the lower surface of the display device 100 by bending the bending area BA, the bezel of the display device 100 can be reduced.

[0094] A driving element DR is mounted on a flexible circuit film (FPC), and lines are formed in the FPC to supply data signals output from the driving element DR and various signals output from the outside to the display area AA. In one embodiment, the driving element DR may be directly mounted in a second non-display area NA2.

[0095] Multiple data lines (DLINK) and multiple signal lines (SLINK) are set in the second non-display area (NA2) and the curved area (BA).

[0096] Multiple data links (DLINKs) are electrically connected to multiple first data lines (DL1) in the first region A1. Multiple signal links (SLINKs) are electrically connected to multiple vertical links (VLINKs) in the first region A1. The connections between the data links (DLINKs) and the first data lines (DL1), and between the signal links (SLINKs) and the vertical links (VLINKs) can be established via solder pad electrodes. Data signals are applied to the multiple data links (DLINKs) and the multiple signal links (SLINKs).

[0097] The data signal is directly applied to the first data line DL1 in the first area A1 of the display area AA via the data connection DLINK, so as to supply the data signal to multiple sub-pixels SP1, SP2, and SP3 corresponding to the sub-pixel columns in the first area A1. The data signal is applied to the second data line DL2 in the second area A2 of the display area AA via the signal connection SLINK, the vertical connection VLINK, and the horizontal connection HLINK, so as to supply the data signal to multiple sub-pixels SP1, SP2, and SP3 corresponding to the sub-pixel columns in the second area A2. The data signal is applied to the third data line DL3 in the third area A3 of the display area AA via the signal connection SLINK, the vertical connection VLINK, and the horizontal connection HLINK, so as to supply the data signal to multiple sub-pixels SP1, SP2, and SP3 corresponding to the sub-pixel columns in the third area A3.

[0098] In the display device 100 of this disclosure, the connection lines that supply data signals to the sub-pixels SP1, SP2, and SP3 in the second region A2 and the third region A3, which are respectively located outside the curved region BA and the second non-display region NA2 in the first direction (width direction, x-axis direction), are not located in the non-display region NA, but are located in the display region AA. Therefore, the border area can be minimized.

[0099] A compensation line COLINK is formed for each of the multiple vertical interconnects VLINK. In one embodiment, the compensation line COLINK can be formed by extending from each vertical interconnect VLINK. Since the vertical interconnect VLINK extends from the lower end of the display area AA to the first contact hole CNT1, the compensation line COLINK can be formed by extending a predetermined distance l from the first contact hole CNT1 along the second direction (y-axis direction).

[0100] In this way, the compensation connection COLINK is formed by extending from the vertical connection VLINK. This is to compensate for the storage capacitance of the data lines DL, thereby eliminating the deviation in storage capacitance between data lines DL with different lengths.

[0101] In the freeform or non-rectangular display device 100, the length of the data line DL varies depending on the position. In particular, the data signal is applied to the sub-pixels SP1, SP2 and SP3 using the vertical connection VLINK and the horizontal connection HLINK, and the storage capacitance formed in the data line DL varies depending on the position.

[0102] This difference in storage capacitance is a major cause of image distortion and quality degradation. Various methods can be used to eliminate this difference in storage capacitance between the data lines DL. For example, the storage capacitance can be compensated by generating parasitic capacitance through the formation of a separate metal pattern in the first non-display area NA1. However, in this case, because the area of ​​the first non-display area NA1 increases due to the metal pattern, there is a problem of increased bezel area of ​​the display device 100.

[0103] In this disclosure, by arranging compensation lines COLINK in the display area AA, the increase in the border area caused by the individual metal pattern can be prevented.

[0104] The compensation link (COLINK) can be configured to extend from the vertical link (VLINK). In one embodiment, the length l of the compensation link (COLINK) is inversely proportional to the lengths of the second data line DL2 in the second region A2 and the third data line DL2 in the third region A3.

[0105] The reason for the storage capacitance deviation in the second data line DL2 and the third data line DL3 is that the lengths of the second data line DL2 and the third data line DL2 are shorter than the length of the first data line DL1. Since the difference in storage capacitance between the first data line DL1 and the second and third data lines DL2 increases as the relative lengths of the second and third data lines DL2 decrease, the length l of the compensation connection COLINK used to compensate for the storage capacitance difference must be inversely proportional to the lengths of the second data line DL2 in the second region A2 and the third data line DL3 in the third region A3.

[0106] That is to say, the compensation line COLINK, which extends from the vertical connection VLINK connecting the shortest second data line DL2 and the third data line DL2 located on the outermost side of the second region A2 and the third region A3 respectively, is the longest, and the length of the compensation line COLINK gradually decreases from the outermost side of the second region A2 and the third region A3 to the first region A1 (i.e., as the length of the second data line DL2 and the third data line DL3 increases).

[0107] As described above, in the display device 100, the pattern for compensating for changes in storage capacitance caused by the length difference of the data line DL is not provided in the non-display area NA of the display device 100, but is provided in the display area AA, thereby minimizing the bezel area.

[0108] The configuration of the display device 100 will be described in more detail below with reference to the accompanying drawings.

[0146] Figure 7 The diagram illustrates the line arrangement in the display area AA of a display device 200 according to another embodiment of this disclosure. In this embodiment of the display device 200, only the arrangement of the horizontal connecting lines HLINK and the vertical connecting lines VLINK differs from those of the display device 100 in the first embodiment; the other configurations are the same as those of the display device 100. Therefore... Figure 7 Only the arrangement of the horizontal HLINK and vertical VLINK is shown. Specifically, the second and third regions, located on either side of the first region A1 of the display area AA, are symmetrical with respect to the first region A1, such that the arrangement of the horizontal HLINK and vertical VLINK in the second and third regions is identical to each other. Therefore, for ease of description, in... Figure 7 Only the first region A1 and the second region A2 of the display area AA are shown.

[0147] Reference Figure 7 In the first region A1 of the display area AA of the display device 200, multiple first data lines DL1 and multiple vertical connecting lines VLINK are arranged along the second direction (vertical direction, y-axis direction). In the second region A2 of the display area AA, multiple second data lines DL2 extending in the second direction are arranged. In this embodiment, the vertical connecting lines VLINK are not arranged in the second region A2.

[0148] The multiple first data lines DL1 arranged in the first region A1 are all formed to have the same length from the bottom to the top of the display area AA. Conversely, the multiple second data lines DL2 arranged in the second region A2 have a length that decreases from the central region to the outside, that is, from the boundary of the first region A1 to the left end.

[0149] Multiple horizontal lines HLINK are set along the first direction (horizontal direction, x-axis direction) in the first area A1 and the second area A2 of the display area AA.

[0150] The horizontal connection HLINK is electrically connected to the vertical connection VLINK in the first region A1 via the first contact hole CNT1. An insulating layer is formed between the horizontal connection HLINK and the second data line DL2 to electrically connect them to each other via the second contact hole CNT2.

[0151] The leftmost vertical connection VLINK in the first region A1 can be electrically connected via the horizontal connection HLINK to the closest second data line DL2 arranged in the second region A2, that is, the rightmost second data line DL2 in the second region A2. Furthermore, the second vertical connection VLINK from the leftmost position in the first region A1 can be electrically connected via the horizontal connection HLINK to the second second data line DL2 from the rightmost position in the second region A2, but this is not a limitation.

[0152] The data signal is directly applied to each first data line DL1 in the first region A1 of the display area AA to supply the data signal to multiple sub-pixels SP1, SP2, and SP3 corresponding to the sub-pixel columns in the first region A1. The data signal is applied to each second data line DL2 in the second region A2 of the display area AA through the vertical connection VLINK and the horizontal connection HLINK to provide the data signal to multiple sub-pixels SP1, SP2, and SP3 corresponding to the sub-pixel columns in the second region A2.

[0153] In the display device 200 of this disclosure, a data signal is provided to a region that is a curved area BA and a second non-display area NA2. Figure 4 The lines connecting sub-pixels SP1, SP2, and SP3 in the outer display area AA, in the first direction of the width direction, are arranged in the display area AA, not in the non-display area NA. Figure 4 In ), the border area can be minimized.

[0154] In one embodiment, according to the display device 200, the multiple horizontal interconnects HLINK provided in the display area DA are not arranged with equal spacing. In the freeform or non-rectangular display device 200, since differences in storage capacitance occur between data lines DL with different lengths, the differences in storage capacitance are compensated by changing the length of the vertical interconnects VLINK connected to the data lines DL according to the length of the data lines DL.

[0155] In other words, the difference in storage capacitance can be compensated by setting the length of the vertical connection line to be inversely proportional to the length of the second data line DL2. For example, the vertical connection line VLINK connected to the outermost second data line DL2 located in the second region A2 is the longest, and the length of the vertical connection line VLINK gradually decreases from the outermost part of the second region A2 to the first region A1.

[0156] In other words, depending on the length of the second data line DL2, the difference in storage capacitance can be compensated by increasing the distance "d" between the horizontal connection HLIN that connects to the vertical connection VLINKK and the second data line DL2. For example, as the lengths of multiple second data lines DL2 decrease, the difference in storage capacitance can be compensated by adjusting the distance "d" between the horizontal connections HLINK that each electrically connects to the corresponding second data line DL2.

[0157] While the circular display device described above applies to freeform or non-rectangular display devices such as watches, this disclosure is not limited to display devices having this specific shape. In one embodiment, the first region A1 may be a rectangular region, and the second region A2 may be a non-rectangular (circular) region, but is not limited thereto.

[0158] This disclosure can be applied to display devices with various shapes other than square or rectangular shapes, or display devices with freeform or non-rectangular partial areas. For example, when some areas have freeform or non-rectangular shapes, the length of the data lines in the freeform areas is reduced, and the storage capacitance of the data lines in the freeform or non-rectangular areas can be compensated for by horizontal and vertical connections provided in the freeform areas. In one embodiment, the first area A1 can be a rectangular area, and the second area A2 can be a non-rectangular area, but is not limited thereto.

[0159] It will be apparent to those skilled in the art that various modifications and variations may be made to this disclosure without departing from its scope. Therefore, this disclosure is intended to cover modifications and variations thereof, provided they fall within the scope of the appended claims and their equivalents.
