DETAILED DESCRIPTION

Various exemplary embodiments of the inventive concept will be described more fully with reference to the accompanying drawings, in which embodiments are shown. This inventive concept may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like reference numerals refer to like elements throughout this application.



FIGS. 1 and 2 are block diagrams illustrating a display apparatus according to exemplary embodiments of the inventive concept.


Referring to FIG. 1, a display apparatus 10 may include a display panel 100, a timing controller 200, a gate driver 300 and a data driver 400.


The display panel 100 operates (e.g., display an image) based on output image data DAT. The display panel 100 includes a plurality of pixels PX, a plurality of data lines DL, a plurality of gate lines GL and a plurality of terminals 120.


The plurality of pixels PX are arranged to form a plurality of pixel rows PR and a plurality of pixel columns PC. For example, the plurality of pixels PX may be arranged in a matrix form, as shown in FIG. 1. Each of the pixel rows PR is formed (e.g., may extend) in a first direction DR1, and each of the pixel columns PC is formed (e.g., may extend) in a second direction DR2 crossing (e.g., substantially perpendicular to) the first direction DR1. For example, the first direction DR1 may be parallel with a relatively long side of each pixel, and may be referred to as a “long-side” direction of each pixel. The second direction DR2 may be parallel with a relatively short side of each pixel, and may be referred to as a “short-side” direction of each pixel. Each of the pixels PX may be electrically connected to a respective one of the gate lines GL and a respective one of the data lines DL.


With continued reference to FIG. 1, each of the plurality of data lines DL extends in the second direction DR2 that is parallel with the plurality of pixel columns PC. The plurality of data lines DL are driven by a plurality of data voltages that are generated from the data driver 400. Each of the data lines DL is connected to at least two adjacent pixels included in a single pixel row. For example, the plurality of data lines DL may be arranged for each of at least two pixel columns per data line. A single data line may be shared by at least two adjacent pixels in a single pixel row, and then at least two adjacent pixels in a single pixel row may receive data voltages through a single data line.


Each of the plurality of gate lines GL extends in the first direction DR1 parallel with the plurality of pixel rows PR. The plurality of gate lines GL are driven by a plurality of gate signals that are generated from the gate driver 300. For example, each of the gate lines GL is connected to at least one pixel included in a single pixel row, and at least two of the gate lines GL are disposed between two adjacent pixel rows. For example, pixels included in a single pixel row may be connected to at least two adjacent gate lines, and then may receive gate signals through at least two adjacent gate lines.


The plurality of terminals 120 receive the plurality of gate signals from the gate driver 300 to transmit the plurality of gate signals to the plurality of gate lines GL. Each of the terminals 120 is electrically connected to a respective one of the gate lines GL, and some of the terminals 120 are connected to some of the gate lines GL with a cross-coupled structure. The cross-coupled structure according to exemplary embodiments will be described with reference to FIGS. 3, 4A, 4B and other example figures.


In some exemplary embodiments of the inventive concept, the plurality of pixels PX may be disposed in a display region of the display panel 100, and the plurality of terminals 120 may be disposed in a peripheral region of the display panel 100. The peripheral region may partially or fully surround the display region. For example, the plurality of terminals 120 may be disposed in the peripheral region of the display panel, and may be adjacent to a first side (e.g., a relatively short side on the left) of the display panel 100.


The timing controller 200 controls an operation of the display panel 100, the gate driver 300 and the data driver 400. The timing controller 200 receives an input image data IDAT and an input control signal ICONT from an external device (e.g., a host or a graphic processor). The input image data IDAT may include a plurality of pixel data for the plurality of pixels PX. The input control signal ICONT may include a master clock signal, a data enable signal, a vertical synchronization signal, a horizontal synchronization signal, etc.


The timing controller 200, for example, may generate the output image data DAT based on the input image data IDAT. For example, the timing controller 200 may selectively perform an image quality compensation, a spot compensation, an adaptive color correction (ACC), and/or a dynamic capacitance compensation (DCC) on the input image data IDAT to generate the output image data DAT. The timing controller 200 may generate a first control signal GCONT and a second control signal DCONT based on the input control signal ICONT. For example, the first control signal GCONT may include, for example, a vertical start signal, a gate clock signal, etc. The second control signal DCONT may include, for example, a horizontal start signal, a data clock signal, a polarity control signal, a data load signal, etc.


With continued reference to FIG. 1, the gate driver 300 generates the plurality of gate signals for driving the gate lines GL based on the first control signal GCONT. For example, the gate driver 300 may sequentially provide the gate signals to the display panel 100 through the gate lines GL. For example, the gate driver 300 may include structure such as a memory, e.g., a plurality of shift registers.


The data driver 400 generates the plurality of data voltages (e.g., analog voltages) for driving the data lines DL based on the output image data DAT (e.g., digital data) and the second control signal DCONT. For example, the data driver 400 may sequentially provide the data voltages to a plurality of lines (e.g., horizontal lines) in the display panel 100 through the data lines DL. For example, the data driver 400 may include structure such as a shift register, a data latch, an analog-to-digital converter and an output buffer.


Referring to FIG. 2, a display apparatus 10a may include a display panel 100a, a timing controller 200, a gate driver 300a and a data driver 400. The display apparatus 10a may further include a printed circuit board (PCB) 201 and/or a flexible PCB (FPCB) 401.


The display apparatus 10a of FIG. 2 may be substantially similar to the display apparatus 10 of FIG. 1. However, the gate driver 300a in FIG. 2 is included in the display panel 100a in FIG. 2, and the display apparatus 10a of FIG. 2 further includes, for example, the PCB 201 and the FPCB 401.


The gate driver 300a may be an amorphous silicon gate (ASG) unit that is integrated in the display panel 100a. In some exemplary embodiments, the plurality of pixels PX may be disposed in a display region of the display panel 100a, and the gate driver 300a and the plurality of terminals 120 may be disposed in a peripheral region of the display panel 100a. The peripheral region may surround the display region. For example, the gate driver 300a may be disposed in the peripheral region, and may be adjacent to a first side (e.g., a relatively short side on the left) of the display panel 100a. The plurality of terminals 120 may be disposed in peripheral region between the gate driver 300a and the display region.


The timing controller 200 may be mounted, for example, on the PCB 201. The data driver 400 may be mounted on the FPCB 401. The FPCB 401 may electrically connect the PCB 201 with the display panel 100a. For example, the PCB 201 and the FPCB 401 may be electrically connected by an anisotropic conductive film (ACF), and the FPCB 401 and the display panel 100a may be electrically connected by the ACF. For example, the FPCB 401 may be adjacent to a second side (e.g., a relatively long side on the upper) of the display panel 100a crossing the first side of the display panel 100a. In other words, the data driver 400 may be connected to the display panel 100a in a tape carrier package (TCP) type.


Although FIG. 2 illustrates an example where the display apparatus 10a includes a single data driver chip and a single FPCB 401, a display apparatus according to exemplary embodiments of the inventive concept may include a plurality of data driver chips. For example, where the display apparatus includes a plurality of data driver chips, the number of the FPCBs on which at least one data driver chip is mounted may be equal to or less than the number of the data driver chips.


Although not illustrated in FIG. 2, the data driver 400 may also be mounted on or integrated in the display panel 100a.


In the display apparatuses 100 and 100a according to exemplary embodiments, shown in FIGS. 1 and 2, the data lines DL may extend in a direction parallel with a short side of each pixel, and thus the number of the data lines DL may be reduced. In addition, a single data line may be shared by at least two adjacent pixels included in a single pixel row, and thus the number of the data lines DL may also be reduced. Further, in the display apparatuses 100 and 100a that have a configuration of reducing the number of the data lines DL, and some of the terminals 120 may be connected to some of the gate lines GL with a cross-coupled structure, and thus a driving order of the gate lines GL may be efficiently changed without excessive design change.



FIG. 3 is a diagram illustrating an example of a portion of a display panel according to an exemplary embodiment of the inventive concept.


Referring to FIG. 3, a display panel may include, for example, first, second, third, fourth, fifth and sixth gate lines GL1, GL2, GL3, GL4, GL5 and GL6, first and second data lines DL1 and DL2, first, second, third, fourth, fifth and sixth pixels P11, P12, P13, P14, P15 and P16, and first, second, third, fourth, fifth and sixth terminals 120a, 120b, 120c, 120d, 120e and 120f. The first through sixth pixels P11˜P16 may form a first repeating pixel group RPG1.


Each of the first through sixth gate lines GL1˜GL6 may extend in a first direction DR1 (see FIG. 3). The first through sixth gate lines GL1˜GL6 may be adjacent to each other, and may be sequentially arranged in a second direction DR2. Each of the first and second data lines DL1 and DL2 may extend in the second direction DR2. The first and second data lines DL1 and DL2 may be adjacent to each other, and may be sequentially arranged in the first direction DR1.


Each of the first through sixth pixels P11-P16 may be included in a respective one pixel row and a respective one pixel column. For example, the first and second pixels P11 and P12 may be included in a first pixel row, and may be adjacent to each other. The third and fourth pixels P13 and P14 may be included in a second pixel row, and may be adjacent to each other. The fifth and sixth pixels P15 and P16 may be included in a third pixel row, and may be adjacent to each other. With the aforementioned arrangement, the second pixel row may be adjacent to the first pixel row, and the third pixel row may be adjacent to the second pixel row. The first, third and fifth pixels P11, P13 and P15 may be included in a first pixel column. The second, fourth and sixth pixels P12, P14 and P16, for example, may be included in a second pixel column that is adjacent to the first pixel column.


Each of the first through sixth pixels P11˜P16 may be electrically connected to a respective one of the first through sixth gate lines GL1˜GL6 and a respective one of the first and second data lines DL1 and DL2. For example, the first and second pixels P11 and P12 may be electrically connected to the first data line DL1, and may be electrically connected to the first and second gate lines GL1 and GL2, respectively. The third and fourth pixels P13 and P14 may be electrically connected to the second data line DL2, and may be electrically connected to the third and fourth gate lines GL3 and GL4, respectively. The fifth and sixth pixels P15 and P16 may be, for example, electrically connected to the first data line DL1, and may be electrically connected to the fifth and sixth gate lines GL5 and GL6, respectively.


The first and second gate lines GL1 and GL2 may be connected to the pixels P11 and P12 that are included in the first pixel row. The first gate line GL1 may be disposed at a first side (e.g., an upper side) with respect to the first pixel row, and the second gate line GL2 may be disposed at a second side (e.g., a lower side) with respect to the first pixel row. In this example, the first gate line GL1 may be referred to as a “top gate line” of the first pixel row, and the second gate line GL2 may be referred to as a “bottom gate line” of the first pixel row. Similarly, the third and fourth gate lines GL3 and GL4 may be referred to as a top gate line of the second pixel row and a bottom gate line of the second pixel row, respectively, and the fifth and sixth gate lines GL5 and GL6 may be referred to as a top gate line of the third pixel row and a bottom gate line of the third pixel row, respectively.


In some exemplary embodiments of the inventive concept, the second and third gate lines GL2 and GL3 may be disposed between the first and second pixel rows, and the fourth and fifth gate lines GL4 and GL5 may be disposed between the second and third pixel rows.


In FIG. 3, each of black squares (▪) that overlap the first, third and fifth pixels P11, P13 and P15 may represent a switching element (e.g., a transistor) connected to the top gate line, and each of white squares (□) that overlap the second, fourth and sixth pixels P12, P14 and P16 may represent a switching element connected to the bottom gate line. In an example of FIG. 3, the switching elements (e.g., ▪ and □) may be arranged between the first and second pixel columns, and thus lengths of wirings that connect the switching elements with the data lines DL1 and DL2 may be substantially the same as each other.


The first through sixth terminals 120a˜120f may sequentially receive first, second, third, fourth, fifth and sixth gate signals G1, G2, G3, G4, G5 and G6. Similar to the first through sixth gate lines GL1-GL6, the first through sixth terminals 120a˜120f may be sequentially arranged in the second direction DR2.

In an example of FIG. 3, three wiring overlapping regions A, B and C may be formed by the cross-coupled structure.


Based on the cross-coupled structure in FIG. 3, the first gate signal G1 may be applied to the first gate line GL1, the second gate signal G2 may be applied to the third gate line GL3, the third gate signal G3 may be applied to the fifth gate line GL5, the fourth gate signal G4 may be applied to the second gate line GL2, the fifth gate signal G5 may be applied to the fourth gate line GL4, and the sixth gate signal G6 may be applied to the sixth gate line GL6.


In some exemplary embodiments, each of the first and second pixels P11 and P12 may be a red pixel outputting red light, each of the third and fourth pixels P13 and P14 may be a green pixel outputting green light, and each of the fifth and sixth pixels P15 and P16 may be a blue pixel outputting blue light.


In some exemplary embodiments, the first repeating pixel group RPG1 may be repeated in the first and second directions DR1 and DR2 to form the display panel according to exemplary embodiments. In other exemplary embodiments, a second repeating pixel group in which the first, second, fifth and sixth pixels P11, P12, P15 and P16 are connected to the second data line DL2, and the third and fourth pixels P13 and P14 are connected to the first data line DL1 may exist, and then the first repeating pixel group RPG1 and the second repeating pixel group may be alternately repeated in the first and second directions DR1 and DR2 to form the display panel according to exemplary embodiments. In the display panel according to exemplary embodiments, the connection of the terminals 120a˜120f with the gate lines GL1˜GL6 in FIG. 3 may be repeated for each of six gate lines.



FIGS. 4A, 4B, 5A and 5B provide diagrams to illustrate a connection structure of a display panel according to exemplary embodiments. FIG. 4A is a plan view of an example of a connection of the terminals with the gate lines in FIG. 3. FIG. 4B is a cross-sectional view taken along line I-I′ in FIG. 4A. FIG. 5A is a plan view of another example of a connection of the terminals with the gate lines in FIG. 3. FIG. 5B is a cross-sectional view taken along line II-II′ in FIG. 5A. For convenience of illustration, elements other than wirings and patterns are omitted in FIGS. 4A and 5A.


Referring now to FIGS. 4A and 4B, the display panel may include the first through sixth gate lines GL1˜GL6 and the first through sixth terminals 120a˜120f. The display panel may further include first, second, third, fourth, fifth and sixth connection patterns 130a, 130b, 130c, 130d, 130e and 130f, first, second, third, fourth, fifth and sixth wirings 142a, 142b, 142c, 142d, 142e and 142f, and contacts 132a, 132b, 132c, 132d, 132e, 132f, 134a, 134b, 134c, 134d, 134e and 134f.


As shown in FIG. 4A, each of the first through sixth wirings 142a˜142f may be electrically connected to a respective one of the first through sixth terminals 120a˜-120f.


Each of the first through sixth connection patterns 130a˜130f may electrically connect a respective one of the first through sixth terminals 120a˜120f with a respective one of the first through sixth gate lines GL1˜GL6. For example, the first connection pattern 130a may electrically connect the first terminal 120a with the first gate line GL1, and may be electrically connected to the first wiring 142a and the first gate line GL1 through the contacts 132a and 134a, respectively. The second connection pattern 130b may electrically connect the second terminal 120b with the third gate line GL3, and may be electrically connected to the second wiring 142b and the third gate line GL3 through the contacts 132b and 134b, respectively. The third connection pattern 130c may electrically connect the third terminal 120c with the fifth gate line GL5, and may be electrically connected to the third wiring 142c and the fifth gate line GL5 through the contacts 132c and 134c, respectively. The fourth connection pattern 130d may electrically connect the fourth terminal 120d with the second gate line GL2, and may be electrically connected to the fourth wiring 142d and the second gate line GL2 through the contacts 132d and 134d, respectively. The fifth connection pattern 130e may electrically connect the fifth terminal 120e with the fourth gate line GL4, and may be electrically connected to the fifth wiring 142e and the fourth gate line GL4 through the contacts 132e and 134e, respectively. The sixth connection pattern 130f may electrically connect the sixth terminal 120f with the sixth gate line GL6, and may be electrically connected to the sixth wiring 142f and the sixth gate line GL6 through the contacts 132f and 134f, respectively.


In some exemplary embodiments of the inventive concept, the gate lines GL1˜GL6 and the wirings 142a˜142f may be disposed in a first wiring layer (e.g., in the same layer), and the connection patterns 130a˜130f may be disposed in a second wiring layer that is different from the first wiring layer. Thus, the second connection pattern 130b may overlap the second gate line GL2 without being electrically connected to the second gate line GL2. The fourth and fifth connection patterns 130d and 130e may overlap the third wiring 142c connected to the third terminal 120c without being electrically connected to the third wiring 142c. An overlapping structure of the second connection pattern 130b and the second gate line GL2 may correspond to the wiring overlapping region A in FIG. 3, an overlapping structure of the fourth connection pattern 130d and the third wiring 142c may correspond to the wiring overlapping region B in FIG. 3, and an overlapping structure of the fifth connection pattern 130e and the third wiring 142c may correspond to the wiring overlapping region C in FIG. 3.


For example, as illustrated in FIG. 4B, the second wiring layer may be disposed on the first wiring layer. In other words, the second and third gate lines GL2 and GL3 and the second wirings 142b may be formed on a substrate (e.g., a semiconductor substrate) 110, and the second connection pattern 130b may be formed on the second and third gate lines GL2 and GL3 and the second wirings 142b. The second connection pattern 130b may be electrically connected to the second wiring 142b and the third gate line GL3 by the contacts 132b and 134b. The second connection pattern 130b may be insulated from the second gate line GL2 by an insulation layer 150.


In some exemplary embodiments, the insulation layer 150 may include a plurality of insulation layers. For example, a first insulation layer may be formed on the substrate 100 on which the gate lines GL2 and GL3 and the wirings 142b are formed, and then may be partially etched to form openings. The contacts 132b and 134b may be formed by filling the openings with conductive material, and then the second connection pattern 130b may be formed to electrically connect the wirings 142b with the gate line GL3. A second insulation layer may be formed on the substrate 100 on which the second connection pattern 130b is formed.


Although not illustrated in FIG. 4B, each of the overlapping structure of the fourth connection pattern 130d and the third wiring 142c and the overlapping structure of the fifth connection pattern 130e and the third wiring 142c may be substantially the same as the overlapping structure of the second connection pattern 130b and the second gate line GL2 in FIG. 4B.


Referring to FIGS. 5A and 5B, the display panel may include the first through sixth gate lines GL1˜GL6 and the first through sixth terminals 120a˜120f, and may further include first, second, third, fourth, fifth and sixth connection patterns 140a, 140b, 140c, 140d, 140e and 140f, the first through sixth wirings 142a˜142f and the contacts 132a˜132f and 134a˜134f.


The display panel of FIGS. 5A and 5B may be substantially the same as the display panel of FIGS. 4A and 4B, except that a cross-sectional structure of the gate lines GL1˜GL6, the wirings 142a˜142f and the connection patterns 140a˜140f is changed in FIGS. 5A and 5B.


In some exemplary embodiments, as illustrated in FIG. 5B, a first wiring layer in which the gate lines GL1˜GL6 and the wirings 142a˜142f are disposed or formed may be disposed on a second wiring layer in which the connection patterns 140a˜140f are disposed or formed. In other words, the second connection pattern 140b may be formed on a substrate (e.g., a semiconductor substrate) 110, and the second and third gate lines GL2 and GL3 and the second wirings 142b may be formed on the second connection pattern 140b. The second connection pattern 140b may be electrically connected to the second wiring 142b and the third gate line GL3 by the contacts 132b and 134b. The second connection pattern 140b may be insulated from the second gate line GL2 by an insulation layer 150.


Although FIGS. 4A, 4B, 5A and 5B illustrates examples of the wirings and the connection patterns, the wirings, the connection patterns and/or the gate lines may have one of various shapes and structures for implementing the cross-coupled structure described with reference to FIG. 3.



FIGS. 6A, 6B, 7A and 7B are diagrams for describing an operation of a display panel according to exemplary embodiments of the inventive concept.


Referring to FIGS. 3 and 6A, in some exemplary embodiments, the first through sixth gate signals G1˜G6 may be sequentially activated. As shown in the example of FIG. 6A, the order of activation is the first, second, third, fourth, fifth and sixth gate signals G1, G2, G3, G4, G5 and G6, but it should be understood that different activation orders are possible. For example, each of the first through sixth gate signals G1˜G6 may have an ON level (e.g., a high level) during one horizontal period 1H. One horizontal period 1H may be defined as a duration for charging a data voltage to a pixel. When the first through sixth gate signals G1˜G6 are activated as illustrated in FIG. 6A, the first through sixth pixels P11˜P16 may be sequentially driven in an order of the first, third, fifth, second, fourth and sixth pixels P11, P13, P15, P12, P14 and P16 (see FIG. 3) based on the activated first through sixth gate signals G1˜G6. In other words, in an example of FIG. 6A, the pixels P11, P13 and P15 that are connected to the top gate lines may be driven first, and then the pixels P12, P14 and P16 that are connected to the bottom gate lines may be driven subsequent to the top gate lines.


Referring to FIGS. 3 and 6B, in other exemplary embodiments, the first through sixth gate signals G1˜G6 may be sequentially activated in an order of the fourth, fifth, sixth, first, second and third gate signals G4, G5, G6, G1, G2 and G3. When the first through sixth gate signals G1˜G6 are activated as illustrated in FIG. 6B, the first through sixth pixels P11˜P16 may be sequentially driven in an order of the second, fourth, sixth, first, third and fifth pixels P12, P14, P16, P11, P13 and P15 based on the activated first through sixth gate signals G1˜G6. In other words, in the example of FIG. 6B, the pixels P12, P14 and P16 that are connected to the bottom gate lines may be driven first, and then the pixels P11, P13 and P15 that are connected to the top gate lines may be driven later.


Referring to FIGS. 3, 7A and 7B, examples of FIGS. 7A and 7B may be substantially similar to the examples of FIGS. 6A and 6B, respectively, except that the examples of FIGS. 7A and 7B operate based on a precharge driving scheme. In the precharge driving scheme, a gate signal may have the ON level during at least two consecutive or successive horizontal periods to increase a charging duration and/or a charging rate. In the examples of FIGS. 7A and 7B, each of the first through sixth gate signals G1˜G6 may have the ON level during six consecutive or successive horizontal periods (e.g. 6H), and activation periods of the first through sixth gate signals G1˜G6 may partially overlap each other, whereas in FIGS. 6A and 6B, the sequential activation periods generally do not overlap each other.


In some exemplary embodiments of the inventive concept, the examples of FIGS. 6A and 6B may be alternately performed for each frame, or the examples of FIGS. 7A and 7B may be alternately performed for each frame. For example, during a first frame period for displaying a first frame image, the first through sixth gate signals G1˜G6 may be driven as illustrated in FIG. 6A (or FIG. 7A). During a second frame period for displaying a second frame image after the first frame period, the first through sixth gate signals G1˜G6 may be driven as illustrated in FIG. 6B (or FIG. 7B).


Although not illustrated in FIGS. 1, 2, 6A, 6B, 7A and 7B, the display panel according to exemplary embodiments may operate based on an inversion driving scheme in which a polarity of a data voltage applied to each pixel is reversed with respect to a common voltage per a set or predetermined period. For example, a data voltage having a first polarity (e.g., a positive polarity) may be applied to the first data line DL1, and a data voltage having a second polarity (e.g., a negative polarity) may be applied to the second data line DL2. The polarity of the data voltage applied to each data line may be changed or reversed at every frame. As the opposite potentials may generate a lateral electric field between adjacent pixels, an artisan should appreciate that techniques such as shielding to avoid a leakage light may be desirable.



FIGS. 8, 9, 10 and 11 are diagrams illustrating examples of a portion of a display panel according to exemplary embodiments of the inventive concept.


Referring to FIG. 8, a display panel may include the first through sixth gate lines GL1˜GL6, the first and second data lines DL1 and DL2, first, second, third, fourth, fifth and sixth pixels P21, P22, P23, P24, P25 and P26, and first through sixth terminals 120a˜120f. The first through sixth pixels P21˜P26 may form a repeating pixel group RPG2.


The repeating pixel group RPG2 of FIG. 8 may be substantially the same as the repeating pixel group RPG1 of FIG. 3, except that an arrangement of the third and fourth pixels P23 and P24 is different in FIG. 8. A person or ordinary skill in the art should appreciate that the inventive concept is not limited to the arrangements of pixels in FIGS. 3 and 8.


With continued reference to FIG. 8, each of the first through sixth pixels P21˜P26 may be included in a respective one pixel row and a respective one pixel column, and may be electrically connected to a respective one of the first through sixth gate lines GL1˜GL6 and a respective one of the first and second data lines DL1 and DL2. For example, the first and second pixels P21 and P22 may be included in a first pixel row. The third and fourth pixels P23 and P24 may be included in a second pixel row that is adjacent to the first pixel row. The fifth and sixth pixels P25 and P26 may be included in a third pixel row that is adjacent to the second pixel row.

In the repeating pixel group RPG2 of FIG. 8, the pixels P21, P23 and P25 that are connected to the top gate lines may be arranged in a zigzag shape, and the pixels P22, P24 and P26 that are connected to the bottom gate lines may be arranged in a zigzag shape.

The first through sixth pixels P31˜P36 may form a repeating pixel group RPG3.


The repeating pixel group RPG3 of FIG. 9 may be substantially the same as the repeating pixel group RPG1 of FIG. 3, except that an arrangement of the switching elements (e.g., ▪ and □) is changed in FIG. 9.


Switching elements (e.g., ▪) of the first and fifth pixels P31 and P35 may be arranged adjacent to the first data line DL1. A switching element (e.g., □) of the fourth pixel P34 may be arranged adjacent to the second data line DL2. Although not illustrated in FIG. 9, according to exemplary embodiments, an arrangement of the switching elements (e.g., ▪ and □) may be changed.


Referring to FIG. 10, a display panel may include the first through sixth gate lines GL1˜GL6, the first and second data lines DL1 and DL2, first, second, third, fourth, fifth and sixth pixels P41, P42, P43, P44, P45 and P46, and first through sixth terminals 120a˜120f. The first through sixth pixels P41˜P46 may form a repeating pixel group RPG4.


The repeating pixel group RPG4 of FIG. 10 may be substantially the same as the repeating pixel group RPG1 of FIG. 3, except that an arrangement of the gate lines GL1˜GL6 is changed in FIG. 10, and a structure of the pixels P41˜P46 is changed in FIG. 10. It should be understood that the inventive concept is not limited to the arrangements shown and described herein.


Each of the first through sixth pixels P41˜P46 may be included in a respective one (e.g. first) pixel row and a respective one (e.g. first) pixel column, and may be electrically connected to a respective one of the first through sixth gate lines GL1˜GL6 and a respective one of the first and second data lines DL1 and DL2. For example, the first and second pixels P41 and P42 may be included in a first pixel row. The third and fourth pixels P43 and P44 may be included in a second pixel row that is adjacent to the first pixel row. The fifth and sixth pixels P45 and P46 may be included in a third pixel row that is adjacent to the second pixel row.

Similarly, the second, third and sixth pixels P42, P43 and P46 may be included in a second pixel column that is adjacent to the first pixel column. The first and second pixels P41 and P42 may be electrically connected to the first data line DL1, and may be electrically connected to the first and second gate lines GL1 and GL2, respectively. The third and fourth pixels P43 and P44 may be electrically connected to the second data line DL2, and may be electrically connected to the third and fourth gate lines GL3 and GL4, respectively. The fifth and sixth pixels P45 and P46 may be electrically connected to the first data line DL1, and may be electrically connected to the fifth and sixth gate lines GL5 and GL6, respectively.


In some exemplary embodiments of the inventive concept, the first and second gate lines GL1 and GL2 may be disposed between the first and second pixel rows, and the third and fourth gate lines GL3 and GL4 may be disposed between the second and third pixel rows. In this example, all switching elements (e.g., □) of the first through sixth pixels P41˜P46 may be connected to the bottom gate lines.


Although not illustrated in FIG. 10, according to exemplary embodiments of the inventive concept, the first and second gate lines GL1 and GL2 may be disposed at a first side (e.g., an upper side) with respect to the first pixel row, the third and fourth gate lines GL3 and GL4 may be disposed between the first and second pixel rows, and the fifth and sixth gate lines GL5 and GL6 may be disposed between the second and third pixel rows. In this example, all switching elements of the pixels may be connected to the top gate lines, as opposed to, for example, all the switching elements being connected to the bottom gate lines.


In the examples shown in FIGS. 8, 9 and 10, the first through sixth terminals 120a˜120f may be connected to the first through sixth gate lines GL1˜GL6 based on the examples described with reference to FIGS. 3, 4A, 4B, 5A and 5B, and the first through sixth gate signals G1˜G6 may be driven based on the examples previously-described with reference to FIGS. 6A, 6B, 7A and 7B.


Referring to FIG. 11, a display panel may include, for example, twelve gate lines (e.g. first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh and twelfth gate lines GL1, GL2, GL3, GL4, GL5, GL6, GL7, GL8, GL9, GL10, GL11 and GL12), first and second data lines DL1 and DL2, twelve pixels (e.g. first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh and twelfth pixels P51, P52, P53, P54, P55, P56, P57, P58, P59 P5A, P5B and P5C), and first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh and twelfth terminals 120a, 120b, 120c, 120d, 120e, 120f, 120g, 120h, 120i, 120j, 120k, 120l. The first through twelfth pixels P51˜P5C may form a first repeating pixel group RPG5.


With continued reference to FIG. 11, each of the first through twelfth gate lines GL1˜GL12 may extend in the first direction DR1. The first through twelfth gate lines GL1˜GL12 may be sequentially arranged in the second direction DR2. Each of the first and second data lines DL1 and DL2 may extend in the second direction DR2.

A m-th terminal among the first through 6*n terminals is connected to a 2*(m−3n)-th gate line, where m is a natural number equal to or greater than (3n+1) and equal to or less than 6*n. Accordingly, the cross-coupled structure according to exemplary embodiments may be implemented.
