[0055] In the specification, the expression that a first component (or region, layer, part, portion, etc.) is “on,” “connected to,” or “coupled to” a second component may mean that the first component may be directly on, directly connected to, or directly coupled to the second component, or may mean that a third component is interposed between the first and second components. The expression that a first component is “directly disposed on,” “directly connected to,” or “directly coupled to” a second component may mean that no third component is interposed between the first and second components.

[0056] The same reference numerals will be assigned to the same components. In addition, in the drawings, the thickness, proportions, and sizes of the components may be exaggerated to effectively describe the technical features. The term "and / or" may include any and all combinations of one or more of the associated components.

[0057] Although the terms "first," "second," etc. may be used to describe various components, these components should not be construed as being limited by these terms. Terms are used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the scope and spirit of the present disclosure. Unless the context clearly indicates otherwise, the singular is intended to include the plural.

[0058] In addition, the terms "below", "at the lower part", "above", and "upper" are used to describe the relationship between the components illustrated in the drawings. The terms are relative and are described with reference to the directions indicated in the drawings.

[0059] It will be further understood that the terms “include” or “comprises” or “has” and variations thereof specify the presence of stated features, quantities, steps, operations, components, parts or combinations thereof, but do not preclude the presence or addition of one or more other features, quantities, steps, operations, components, parts and / or combinations thereof.

[0060] Unless otherwise defined, all terms (including technical and scientific terms) used in the specification have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. In addition, terms defined in dictionaries and commonly used should be interpreted as having a meaning consistent with the meaning in the context of the relevant technology, and should not be interpreted in an idealized or overly formal sense unless explicitly defined herein.

[0061] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0062] Figure 1 is a perspective view of a display device according to an embodiment of the present disclosure.

[0063] refer to Figure 1 The display device DD may be a device activated in response to an electrical signal. The display device DD may include an active area 1000A and a peripheral area 1000NA. The display device DD may display an image in the active area 1000A. The active area 1000A may include a surface defined by a first direction DR1 and a second direction DR2. The peripheral area 1000NA may be disposed adjacent to the active area 1000A. The peripheral area 1000NA may surround the active area 1000A. According to an embodiment of the present disclosure, the peripheral area 1000NA may be omitted.

[0064] The thickness direction of the display device DD may be parallel to a third direction DR3 crossing the first direction DR1 and the second direction DR2. Accordingly, the front surface (or top surface) and the rear surface (or bottom surface) of the member of the display device DD may be defined in the third direction DR3.

[0065] According to an embodiment of the present disclosure, the display device DD may be an emissive display. However, the present disclosure is not limited thereto. For example, the display device DD may be an organic light-emitting display device, a quantum dot light-emitting display device, a micro light-emitting diode (LED) display device, or a nano-LED display device. The light-emitting layer of the organic light-emitting display device may include an organic light-emitting material.

These display devices are examples, and the display device may be applied to various other applications without departing from the scope of the present disclosure.

[0067] Figure 2 is a perspective view of a display device according to an embodiment of the present disclosure.

[0068] refer to Figure 2 The display device DD-1 may include a folding area FA and a non-folding area. The non-folding area may include a first non-folding area NFA1 and a second non-folding area NFA2. The folding area FA may be located between the first non-folding area NFA1 and the second non-folding area NFA2.

[0069] like Figure 2 As shown in FIG, the folding area FA can be folded about a folding axis FX. The folding axis FX can be parallel to the second direction DR2. When the display device DD-1 is folded, the folding area FA can have a specific curvature and a specific radius of curvature. When the display device DD-1 is in a closed state, the first non-folding area NFA1 and the second non-folding area NFA2 can face each other so that the display surface is not exposed to the outside. For example, in the closed state, the display device DD-1 can be folded about the folding axis FX, and the opposing edges of the first non-folding area NFA1 and the second non-folding area NFA2 can be close together.

[0070] According to an embodiment of the present disclosure, the display device DD-1 can be in an open state, such that the display surface is exposed to the outside. For example, in the open state, the opposing edges of the first non-folding area NFA1 and the second non-folding area NFA2 can be spaced apart from each other. According to an embodiment of the present disclosure, the display device DD-1 can be in a closed state or an open state. However, the present disclosure is not limited thereto.

[0071] although Figure 2 The folding axis FX is shown to be defined in the display device DD-1, but the present disclosure is not limited thereto. For example, the display device DD-1 may include a plurality of folding axes defined therein and may be in an unfolded state to a closed state or an open state.

[0072] although Figure 1 and Figure 2A bar-type display device DD and a foldable-type display device DD-1 are illustrated, but the present disclosure is not limited thereto. For example, the following description will be applied to various electronic devices such as a curved electronic device, a rollable electronic device, or a slidable electronic device.

[0073] Figure 3 is a block diagram of a display device according to an embodiment of the present disclosure.

[0074] refer to Figure 3 , the display device DD may include a driving controller TC, a data driving circuit DDC, a demultiplexer DM, a first driving circuit SDC1 , a second driving circuit SDC2 , and pixels PXij disposed in the active area 1000A.

[0075] The display device DD may include a plurality of scan lines. For example, the display device DD may include first scan lines GWL1 to GWLn, second scan lines GIL1 to GILn, and third scan lines GBL1 to GBLn. The display device DD may include emission control lines EML1 to EMLn and data lines DL1 to DLm. In this case, n and m are integers greater than 1.

[0076] The data lines DL1 to DLm may be connected to the demultiplexer DM. The data lines DL1 to DLm may be connected between the demultiplexer DM and the active area 1000A. The data lines DL1 to DLm may be arranged in a first direction DR1, and each of the data lines DL1 to DLm may extend in a second direction DR2.

[0077] The first scan lines GWL1 to GWLn may be connected to the first drive circuit SDC1. The first scan lines GWL1 to GWLn may be connected between the first drive circuit SDC1 and the active area 1000A. The first scan lines GWL1 to GWLn may be arranged in the second direction DR2, and each of the first scan lines GWL1 to GWLn may extend in the first direction DR1.

[0078] The second scan lines GIL1 to GILn may be connected to the first drive circuit SDC1. The second scan lines GIL1 to GILn may be connected between the first drive circuit SDC1 and the active area 1000A. The second scan lines GIL1 to GILn may be arranged in the second direction DR2, and each of the second scan lines GIL1 to GILn may extend in the first direction DR1.

[0079] The third scan lines GBL1 to GBLn may be connected to the first drive circuit SDC1. The third scan lines GBL1 to GBLn may be connected between the first drive circuit SDC1 and the active area 1000A. The third scan lines GBL1 to GBLn may be arranged in the second direction DR2, and each of the third scan lines GBL1 to GBLn may extend in the first direction DR1.

[0080] The emission control lines EML1 to EMLn may be connected to the second drive circuit SDC2. The emission control lines EML1 to EMLn may be connected between the second drive circuit SDC2 and the active area 1000A. The emission control lines EML1 to EMLn may be arranged in the second direction DR2, and each of the emission control lines EML1 to EMLn may extend in the first direction DR1.

[0081] The display device DD may include a plurality of pixels connected to first scan lines GWL1 to GWLn, second scan lines GIL1 to GILn, third scan lines GBL1 to GBLn, emission control lines EML1 to EMLn, and data lines DL1 to DLm. As a representative example, Figure 3 The pixel PXij is shown. The pixel PXij can be electrically connected to the first scan line GWLi among the first scan lines GWL1 to GWLn and the data line DLj among the data lines DL1 to DLm, where i is an integer greater than 1 and less than or equal to n, and j is an integer greater than 1 and less than or equal to m. Although Figure 3 The first scan line GWLi among the first scan lines GWL1 to GWLn is shown to be connected to the pixel PXij, but the present disclosure is not limited thereto. For example, an additional scan line may be connected to the pixel PXij. The lines connected to the pixel PXij will be described herein.

[0082] The driver controller TC can receive input image signals RGB and a control signal CTRL. The driver controller TC can generate an image data signal DATA. The image data signal DATA can be formed by converting the data format of the image signal RGB to match the interface specification of the data driver circuit DDC. Furthermore, the driver controller TC can generate a first control signal DCS for controlling the data driver circuit DDC, a second control signal SCS for controlling the first driver circuit SDC1, and a third control signal ECS for controlling the second driver circuit SDC2.

[0083] According to an embodiment of the present disclosure, the display device DD may further include channel lines CL1 to CLx. The channel lines CL1 to CLx may be connected between the data driving circuit DDC and the demultiplexer DM. The channel lines CL1 to CLx may be selectively electrically connected to the data lines DL1 to DLm through the demultiplexer DM. The number of channel lines CL1 to CLx may be less than the number of data lines DL1 to DLm. More generally, x is an integer greater than 1 and less than m. Although the demultiplexer DM is included in the display device DD as an example, the present disclosure is not limited thereto. For example, the demultiplexer DM may be included in the data driving circuit DDC, implemented in the form of a separate integrated circuit, or integrated into a printed circuit board on which the data driving circuit DDC is mounted.

[0084] According to an embodiment of the present disclosure, due to the demultiplexer DM, the number of channels of data output from the data driver circuit DDC can be less than the number of data lines DL1 to DLm. The number of channels can correspond to the number of channel lines CL1 to CLx. In this case, the number of integrated circuit (IC) chips including the data driver circuit DDC included in the display device DD can be reduced as the number of channels decreases. In addition, as the number of channels of a single IC chip including the data driver circuit DDC decreases, the cost of the IC chip can be reduced.

[0085] The data drive circuit DDC may receive a first control signal DCS and an image data signal DATA from a drive controller TC. The data drive circuit DDC may convert the image data signal DATA into a data signal and output the data signal to the channel lines CL1 to CLx. The data signal may be an analog voltage corresponding to the grayscale value of the image data signal DATA. The demultiplexer DM may electrically connect some of the data lines DL1 to DLm to the channel lines CL1 to CLx, and the data signal may be output to some of the data lines DL1 to DLm.

[0086] The first drive circuit SDC1 may be connected to the first scan lines GWL1 to GWLn, the second scan lines GIL1 to GILn, and the third scan lines GBL1 to GBLn. The second drive circuit SDC2 may be connected to the emission control lines EML1 to EMLn. The first drive circuit SDC1 and the second drive circuit SDC2 may receive first and second control signals SCS and ECS, respectively, from a drive controller TC and may apply scan signals to the first scan lines GWL1 to GWLn, the second scan lines GIL1 to GILn, the third scan lines GBL1 to GBLn, and the emission control lines EML1 to EMLn based on the first and second control signals SCS and ECS.

[0087] The scan signal can be set to a voltage for turning on the transistor receiving the scan signal. For example, the scan signal applied to the P-type transistor can be set to a logic low level, and the scan signal applied to the N-type transistor can be set to a logic high level. Hereinafter, the meaning of "applying a scan signal" or "activating a scan signal" can be understood as applying a scan signal at a logic level for turning on the transistor controlled by the scan signal.

[0088] According to an embodiment of the present disclosure, the first driver circuit SDC1 and the second driver circuit SDC2 may be spaced apart from each other, and the active area 1000A may be interposed between the first driver circuit SDC1 and the second driver circuit SDC2. However, the present disclosure is not limited thereto. For example, the first driver circuit SDC1 and the second driver circuit SDC2 may be disposed on the same side of the active area 1000A, or at least a portion of the first driver circuit SDC1 and the second driver circuit SDC2 may be disposed within the active area 1000A.

[0162] Figure 9 is a timing diagram illustrating the operation of the display device according to an embodiment of the present disclosure.

[0163] refer to Figure 4 、 Figure 5A 、 Figure 5B 、 Figure 8A 、 Figure 8B and Figure 9 During the first subframe period HFR1, the first control signal CLA may be alternately and repeatedly applied with an activation level and a deactivation level, and the second control signal CLB may have a deactivation level. Referring to the first control signal CLA and the second control signal CLB, the activation level may be a low level, and the deactivation level may be a high level.

[0164] During the first subframe period HFR1, the first clock signal GCLA may have an activation level, and the second clock signal GCLB may have a deactivation level. For example, in the first subframe period HFR1, in response to activation of the first control signal CLA in the first subframe period HFR1, the first clock signal GCLA may be transitioned to an activation level, and the second clock signal GCLB may be transitioned to a deactivation level. In the first subframe period HFR1, throughout multiple clock cycles of the first control signal CLA, the first clock signal GCLA may be maintained at an activation level, and the second clock signal GCLB may be maintained at a deactivation level. With reference to the first clock signal GCLA and the second clock signal GCLB, the activation level may be a low level, and the deactivation level may be a high level.

[0165] During the first subframe period HFR1, one of the third transistors T3-1 and T3-2, one of the fourth transistors T4-1 and T4-2, and one of the seventh transistors T7-1 and T7-2 of the first group of pixels GP1 may be turned on in response to the first clock signal GCLA. For example, the 3-1st transistor T3-1, the 4-1st transistor T4-1, and the 7-1st transistor T7-1 may be turned on in response to the first clock signal GCLA. During the first subframe period HFR1, the first group of pixels GP1 may emit light from the light-emitting element ED in response to the first scan signal GW.

For example, the 3-1st transistor T3-1, the 4-1st transistor T4-1, and the 7-1st transistor T7-1 may be turned off in response to the second clock signal GCLB. During the first subframe period HFR1, the second group of pixels GP2 may not emit light from the light emitting element ED.

[0167] During the first subframe period HFR1, the plurality of first scan lines GWL1, GWL2, GWL3, and GWL4 may be sequentially activated. For example, the first scan signals GW1, GW2, GW3, GW4 to GWn-1 and GWn applied to the first scan lines GWL1 to GWLn may sequentially have an activation level (e.g., a low level).

[0168] During the first subframe period HFR1 , the data signal DT may be applied to a first group of pixels GP1 connected to the first group of data lines DL1 - 1 , DL1 - 2 , DL1 - 3 , and DL1 - 4 among the first to fourth pixels PX11 to PX18 , PX21 to PX28 , PX31 to PX38 , and PX41 to PX48 .

[0169] During the second subframe period HFR2 , the first control signal CLA may have a deactivation level, and the second control signal CLB may be alternately and repeatedly applied with an activation level and a deactivation level.

[0170] During the second subframe period HFR2, the second clock signal GCLB may have an activation level, and the first clock signal GCLA may have a deactivation level. The activation period of the first clock signal GCLA may not overlap with the activation period of the second clock signal GCLB. That is, the activation period of the first clock signal GCLA may be in a state that does not overlap with the activation period of the second clock signal GCLB. For example, in the second subframe period HFR2, in response to the activation of the second control signal CLB, the first clock signal GCLA may be changed to a deactivation level, and the second clock signal GCLB may be changed to an activation level. In the second subframe period HFR2, throughout multiple clock cycles of the second control signal CLB, the first clock signal GCLA may be maintained at the deactivation level, and the second clock signal GCLB may be maintained at the activation level.

[0171] During the second subframe period HFR2, in the first group of pixels GP1, one of the third transistors T3-1 and T3-2, one of the fourth transistors T4-1 and T4-2, and one of the seventh transistors T7-1 and T7-2 may be turned off in response to the first clock signal GCLA. For example, the 3-1st transistor T3-1, the 4-1st transistor T4-1, and the 7-1st transistor T7-1 may be turned off in response to the first clock signal GCLA. During the second subframe period HFR2, the first group of pixels GP1 may not emit light from the light emitting element ED.

[0172] During the second subframe period HFR2, in the second group of pixels GP2, one of the third transistors T3-1 and T3-2, one of the fourth transistors T4-1 and T4-2, and one of the seventh transistors T7-1 and T7-2 may be turned on in response to the second clock signal GCLB. For example, the 3-1st transistor T3-1, the 4-1st transistor T4-1, and the 7-1st transistor T7-1 may be turned on in response to the second clock signal GCLB. During the second subframe period HFR2, the second group of pixels GP2 may emit light from the light-emitting element ED in response to the first scan signal GW.

[0173] During the second subframe period HFR2, the first scan lines GWL1, GWL2, GWL3, and GWL4 may be sequentially activated. For example, the first scan signals GW1, GW2, GW3, GW4 to GWn-1 and GWn applied to the first scan lines GWL1 to GWLn may sequentially have activation levels.

[0174] During the second subframe period HFR2, the data signal DT may be applied to the second group of pixels PX21 to PX28 and PX41 to PX48 connected to the second group of data lines DL2-1, DL2-2, DL2-3 and DL2-4 among the first to fourth pixels PX11 to PX18, PX21 to PX28, PX31 to PX38 and PX41 to PX48.

In some embodiments, the pixel area can be reduced compared to the case where the first group of pixels GP1 and the second group of pixels GP2 are connected to different scan lines. In some embodiments, the number of pixels arranged in the same area can be increased. Accordingly, the display device DD (see Figure 1 ) can be achieved with high resolution.

[0176] In a comparative embodiment, when the first group of pixels GP1 and the second group of pixels GP2 are connected to different first scan lines, a plurality of first drive circuits SDC1 may be provided to output first scan signals GW to drive the first group of pixels GP1 and the second group of pixels GP2, respectively. According to an embodiment of the present disclosure, the first drive circuit SDC1 may be used to provide the first scan signal GW. The first group of pixels GP1 and the second group of pixels GP2 may be driven separately by the first clock signal GCLA and the second clock signal GCLB. Accordingly, a plurality of first drive circuits SDC1 may be provided in the peripheral area 1000NA (see Figure 1 ) with a reduced area display device DD (see Figure 1 ).

[0177] In addition, according to an embodiment of the present disclosure, the first scanning signal GW can be provided by using the first driving circuit SDC1. In this case, the amount of power consumed in the first driving circuit SDC1 can be reduced compared to the amount of power consumed when the first scanning signal GW is applied separately to the first group of pixels GP1 and the second group of pixels GP2 to drive the first group of pixels GP1 and the second group of pixels GP2. Accordingly, the display device DD (see Figure 1 ) power consumption.

For example, the first scan stage ST1-1, the fifth scan stage ST5-1, and the ninth scan stage ST9-1 that receive the first scan clock signal CLK1-1 at the first input node and the second scan clock signal CLK2-1 at the second input node can belong to multiple first scan stages. The second scan stage ST2-1 and the sixth scan stage ST6-1 that receive the second scan clock signal CLK2-1 at the first input node and the third scan clock signal CLK3-1 at the second input node can belong to multiple second scan stages. The third scan stage ST3-1 and the seventh scan stage ST7-1 that receive the third scan clock signal CLK3-1 at the first input node and the fourth scan clock signal CLK4-1 at the second input node can belong to multiple third scan stages. The fourth scan stage ST4-1 and the eighth scan stage ST8-1 that receive the fourth scan clock signal CLK4-1 at the first input node and the first scan clock signal CLK1-1 at the second input node can belong to multiple fourth scan stages.

[0241] Among the plurality of scanning stages ST1-1 to ST9-1, the first scanning stage ST1-1 may receive a start signal FLM which may serve as a carry signal of the first scanning stage ST1-1. The first scanning stage ST1-1 may receive a start signal FLM from the driving controller TC (see Figure 3 )Receive the start signal FLM.

[0242] The phases of the first scanning clock signal CLK1-1, the second scanning clock signal CLK2-1, the third scanning clock signal CLK3-1, and the fourth scanning clock signal CLK4-1 may be sequentially shifted. In the first scanning clock signal CLK1-1, the second scanning clock signal CLK2-1, the third scanning clock signal CLK3-1, and the fourth scanning clock signal CLK4-1, the first voltage and the second voltage may be repeated at a specific cycle.

[0243] According to the present disclosure, when four clock signals such as a first scan clock signal CLK1-1, a second scan clock signal CLK2-1, a third scan clock signal CLK3-1, and a fourth scan clock signal CLK4-1 are used, the capacitance of each of the first scan clock signal CLK1-1, the second scan clock signal CLK2-1, the third scan clock signal CLK3-1, and the fourth scan clock signal CLK4-1 can be reduced by half, and the period can be doubled compared to when two clock signals are used. Since each of the capacitance and the frequency can be reduced by half, the power consumption can be reduced to one-quarter (i.e., 1 / 4). Accordingly, a display device DD with reduced power consumption can be provided (see Figure 1 ).

[0244] As described above, the first group of pixels and the second group of pixels can be connected to the same first scan line. Compared to the case where the first group of pixels and the second group of pixels can be connected to different scan lines, the pixel area can be reduced. A first drive circuit can be used to apply a first scan signal to the first group of pixels and the second group of pixels. The first group of pixels and the second group of pixels can be driven separately in response to a first clock signal and a second clock signal. The area of the non-display area can be reduced. In addition, the first drive circuit can be used to apply the first scan signal. In this case, compared to the case of driving multiple first drive circuits, the power consumption in the first drive circuit can be reduced. Accordingly, the display device can have reduced power consumption.

[0245] Although the embodiments of the present disclosure have been described for illustrative purposes, it will be understood by those skilled in the art that various modifications and substitutions are possible without departing from the scope and spirit of the present disclosure as disclosed in the claims. Accordingly, the technical scope of the present disclosure is not limited to the detailed description of this specification, but should be defined by the claims.

[0246] While the present disclosure has been described with reference to the embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the disclosure as set forth in the claims.
