[0053] By referring to the detailed description and accompanying drawings of the following embodiments, it is easier to understand the features of the inventive concept and the method for realizing the inventive concept. Below, the embodiments will be described in more detail with reference to the accompanying drawings, in which the same reference numerals always indicate the same elements. However, the present invention can be embodied in various different forms and should not be interpreted as being limited to the embodiments shown here. On the contrary, these embodiments are provided as examples so that the disclosure will be thorough and complete, and these embodiments will fully convey the aspects and features of the present invention to those skilled in the art. Therefore, it is not necessary to describe the processes, elements and techniques for fully understanding the aspects and features of the present invention for those skilled in the art. Unless otherwise specified, the same reference numerals indicate the same elements throughout the drawings and written descriptions, so the same reference numerals will not be repeatedly described. In the drawings, for clarity, the relative sizes of elements, layers and regions are exaggerated.

[0054] In the following description, for the purpose of explanation, numerous specific details are set forth to provide a thorough understanding of the various embodiments. However, it is apparent that the various embodiments can be practiced without these specific details or with one or more equivalent arrangements. In other cases, in order to avoid making the various embodiments unnecessarily obscure, well-known structures and devices are shown in the form of block diagrams.

[0055] It will be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, regions, layers and / or parts, however, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, without departing from the spirit and scope of the present invention, the first element, first component, first region, first layer or first part described below may be referred to as the second element, second component, second region, second layer or second part.

[0056] For ease of explanation, spatially relative terms such as "below", "below", "below", "below", "above", "above" and the like may be used here to describe the relationship between one element or feature and another element or features as shown in the accompanying drawings. It will be understood that the spatially relative terms are intended to cover different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure is turned over, the element described as "below" or "below" or "below" other elements or features will then be positioned "above" the other elements or features. Therefore, the example terms "below" and "below" can cover both above and below orientations. The device may be positioned otherwise (e.g., rotated 90 degrees or in other orientations), and the spatially relative descriptors used here should be interpreted accordingly.

[0057] It will be understood that when an element, layer, region, or component is referred to as being "on," "connected to," or "coupled to" another element, layer, region, or component, the element, layer, region, or component may be directly on, directly connected to, or directly coupled to the other element, layer, region, or component, or one or more intermediate elements, layers, regions, or components may also be present. However, "directly connected / directly coupled" means that one component is directly connected or directly coupled to another component without the presence of intermediate components. In addition, it will be understood that when an element or layer is referred to as being "between" two elements or layers, the element or layer may be the only element or the only layer between the two elements or layers, or one or more intermediate elements or layers may also be present.

[0058] For the purpose of this disclosure, "at least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" may be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as, for example, XYZ, XYY, YZ, and ZZ. Like reference numerals refer to like elements throughout. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0059] The terms used herein are only used for the purpose of describing specific embodiments, and are not intended to limit the present invention. As used herein, the singular forms "one" and "one (kind / person)" are also intended to include plural forms, unless otherwise clearly indicated in the context. It will also be understood that when the terms "include", "comprise" and their variations are used in this specification, the description indicates the presence of the features, integral bodies, steps, operations, elements, components and / or their groups, but does not exclude the presence or addition of one or more other features, integral bodies, steps, operations, elements, components and / or their groups. As used herein, the term "and / or" includes any combination and all combinations of one or more related listed items. When an expression such as "at least one of ..." appears after a column of elements (elements), the expression modifies the entire column of elements (elements), and does not modify the single element (element) in the column.

[0060] As used herein, the terms "substantially," "approximately," and similar terms are used as terms of approximation and not as terms of degree, and are intended to account for the inherent deviations in measurements or calculations that one of ordinary skill in the art would recognize. Additionally, the use of "may" when describing embodiments of the present invention refers to "one or more embodiments of the present invention." As used herein, the term "exemplary" means an example or illustration.

[0061] When a certain embodiment can be implemented differently, a specific process order can be performed differently from the described order. For example, two consecutively described processes can be performed substantially simultaneously or in the reverse order of the described order.

[0062] Various embodiments are described herein with reference to cross-sectional views that are schematic diagrams of embodiments and / or intermediate structures. As such, variations in the shapes of the illustrations due to, for example, manufacturing techniques and / or tolerances are to be expected. Therefore, the embodiments disclosed herein should not be construed as limited to the shapes of the specifically illustrated regions, but will include deviations in shapes due to, for example, manufacturing. For example, an implanted region illustrated as a rectangle will typically have rounded or curved features and / or a gradient of implant concentration at its edges, rather than a binary change from an implanted region to a non-implanted region. Similarly, a buried region formed by implantation may result in some implantation in the region between the buried region and the surface through which the implantation occurs. Therefore, the regions illustrated in the drawings are schematic in nature, and their shapes are not intended to illustrate the actual shape of a region of the device, and are not intended to be limiting.

[0063] Any suitable hardware, firmware (e.g., a dedicated integrated circuit), software, or a combination of software, firmware, and hardware may be used to implement the electronic or electrical devices and / or any other related devices or components according to the embodiments of the present invention described herein. For example, the various components of these devices may be formed on an integrated circuit (IC) chip or on separate IC chips. In addition, the various components of these devices may be implemented on a flexible printed circuit film, a tape carrier package (TCP), a printed circuit board (PCB), or may be formed on a substrate. In addition, the various components of these devices may be processes or threads that run on one or more processors in one or more computing devices, execute computer program instructions, and interact with other system components for performing the various functions described herein. The computer program instructions are stored in a memory, which may be implemented in a computing device using a standard memory device such as a random access memory (RAM) as an example. The computer program instructions may also be stored in other non-temporary computer-readable media such as CD-ROMs, flash drives, and the like as examples. In addition, it should be appreciated by those skilled in the art that, without departing from the spirit and scope of the embodiments of the present invention, the functions of various computing devices may be combined or integrated into a single computing device, or the functions of a particular computing device may be distributed to one or more other computing devices.

[0064] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present invention belongs. It will also be understood that terms (such as those defined in common dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and / or this specification, and should not be interpreted in an idealized or overly formal sense, unless explicitly defined as such herein.

[0065] Figures 1A to 1C FIG. 1 shows a wearable device according to an embodiment of the present invention and how a display device is installed on the wearable device. Figures 1A to 1C , an HMD is shown as an embodiment of a wearable device, but the wearable device according to the present invention is not limited thereto.

[0066] Reference Figure 1A to Figure 1B , the wearable device 30 according to the present embodiment may include a frame 31. A band 32 may be connected to the frame 31, and a user may wear the frame 31 around the head by using the band 32. The frame 31 has a structure to which the display device 10 can be detachably mounted.

[0067] In some embodiments, the display device 10 that can be mounted on the wearable device 30 can be a smart phone, but it is not limited thereto. For example, the display device 10 can be any electronic device that can be mounted on the wearable device 30 and includes a display means, such as a tablet PC, an e-book reader, a computer, a workstation, a personal digital assistant (PDA), a portable multimedia player (PMP), a camera, etc.

[0068] In some embodiments, when the display device 10 is mounted on the frame 31, the connection portion 11 of the display device 10 and the connection portion 33 of the frame 31 may be electrically connected to each other. Therefore, communication between the wearable device 30 and the display device 10 may be enabled. In order to control the display device 10 mounted on the frame 31, the wearable device 30 may include at least one of a touch sensor, a button, and a scroll wheel key.

[0069] When the display device 10 is mounted on the wearable device 30, the display device 10 can be operated as an HMD device. For example, when the display device 10 is separated from the wearable device 30, the display device 10 can be driven in a first mode. When the display device 10 is mounted on the wearable device 30, the display device 10 can be driven in a second mode, in which a valid image (e.g., a desired image) is displayed in an area different from an area in which the valid image is displayed in the first mode. In some embodiments, the first mode may be a normal display mode (e.g., a normal mode) in which an image is displayed in the entire display area of ​​the display device 10, and the second mode of the display device 10 may be a partial display mode (e.g., a VR mode) in which an image is displayed only in some parts of the display area.

[0070] In some embodiments, the driving mode of the display device 10 may be switched automatically or manually. For example, when the display device 10 is mounted on the wearable device 30, the driving mode of the display device 10 may be automatically switched to the second mode, or may be switched to the second mode by the user's setting. However, when the display device 10 is separated from the wearable device 30, the driving mode of the display device 10 may be automatically switched to the first mode, or may be switched to the first mode by the user's setting.

[0071] In some embodiments, the wearable device 30 may include a lens 20 corresponding to the user's eye. For example, the wearable device 30 may include a left-eye lens 21 corresponding to the user's left eye and a right-eye lens 22 corresponding to the user's right eye. However, the present invention is not limited to a wearable device 30 including a left-eye lens 21 and a right-eye lens 22. For example, a wearable device 30 according to another embodiment may include an integrated lens 20 so that the left eye and the right eye can see the same image in parallel or simultaneously. In some embodiments, the lens 20 may be a fisheye lens or a wide-angle lens to improve the user's field of view (FOV), but it is not limited thereto.

[0072] When the display device 10 is fixed to the frame 31, the user can see the image displayed by the display device 10 via the lens 20. Therefore, it is possible to achieve the effect of viewing a video image on a large screen at a certain distance.

[0073] Reference Figure 1C , when the display device 10 is mounted on the wearable device 30, some areas of the display device 10 will be covered by the frame 31. For example, when the display device 10 is mounted on the wearable device 30, some display areas of the display device 10 will be covered by the frame 31.

[0074] For example, after the display device 10 is mounted on the wearable device 30, the central portion of the display area of ​​the display device 10 (which may include an area recognized by the user through the lens 20 of the wearable device 30) can become a visible display area VDA. In addition, the remaining portion of the display area of ​​the display device 10 (e.g., the peripheral portion of the display area) can become a non-visible display area NVDA covered by the frame 31.

[0075] In some embodiments, the central portion of the display device 10 can be divided into a visible display area VDA and a non-visible display area NVDA, so that more vivid images can be displayed to the user. For example, the area of ​​the central portion of the display device 10 corresponding to each of the left eye lens 21 and the right eye lens 22 can be set as the visible display area VDA, and the other areas of the display device 10 can be set as the non-visible display area NVDA. In this case, the image displayed in the visible display area VDA can be controlled according to each of the left eye lens 21 and the right eye lens 22, respectively, so that a 3D image can be realized. When the display device 10 is mounted on the wearable device 30 and driven in the second mode, a valid image can be displayed in the visible display area VDA in the central portion. In addition, in the non-visible display area NVDA, no image may be displayed, or a black image or a dummy image may be displayed.

[0076] On the other hand, when the display device 10 is separated from the wearable device 30 and driven in the first mode, the entire display area of ​​the display device 10 can be recognized by the user. That is, when the display device 10 is separated from the wearable device 30, the entire display area can become the visible display area VDA. In this case, a valid image can be displayed in the entire display area of ​​the display device 10.

[0077] That is, the display device 10 according to the present embodiment can be driven differently according to the first mode and the second mode. For example, the display device 10 can display effective images in different areas depending on whether the display device 10 is in the first mode or the second mode.

[0078] As in the present embodiment, when the display device 10 is used together with the wearable device 30, various types of images can be experienced. However, because the area for displaying an effective image when the display device 10 is driven in the first mode is different from the area for displaying an effective image when the display device 10 is driven in the second mode, the boundary line between the visible display area VDA and the non-visible display area NVDA is recognized when the driving mode of the display device 10 is switched.

[0079] For example, assuming that the display device 10 displays an image only in the visible display area VDA in the central portion, and assuming that the driving of the non-visible display area NVDA is stopped, the hysteresis of the driving transistors set in the pixels of the visible display area VDA will be different from the hysteresis of the driving transistors set in the pixels of the non-visible display area NVDA. Therefore, when the display device 10 is switched to the first mode after the display device 10 has been driven in the second mode for a period of time (a predetermined period of time), a brightness deviation will occur between the visible display area VDA that has been driven as a display area in the second mode and the display area that has become the non-visible display area NVDA, so that the boundary line will be recognized.

[0080] Therefore, in the embodiments to be described below, a display device and a driving method thereof are proposed, which can reduce or prevent the recognition of boundary lines between multiple areas forming a display area, and can reduce or prevent the generation of image retention or light leakage interference, or can minimize image retention or light leakage interference.

[0081] Figure 2 A display device according to an embodiment of the present invention is schematically shown.

[0082] Reference Figure 2According to the present embodiment, the display device 10 includes a display area AA and a peripheral area NA. In some embodiments, the display area AA may be an active area in which a plurality of pixels PXL1, PXL2, and PXL3 are arranged to display an image. The peripheral area NA may be a non-active area surrounding the display area AA, and may correspond to a portion of the display device 10 that does not include the display area AA.

[0083] The display area AA may include at least two pixel areas arranged adjacent to each other. For example, the display area AA may include a first pixel area AA1, a second pixel area AA2, and a third pixel area AA3, which are sequentially arranged from one side of the display device 10. A plurality of pixels PXL1, PXL2, and PXL3 may be respectively disposed in the pixel areas AA1, AA2, and AA3. These pixels PXL1, PXL2, and PXL3 may be used to display an image in the display area AA.

[0084] In some embodiments, the first pixel area AA1 is disposed on one side of the second pixel area AA2, and the third pixel area AA3 may be disposed on the other side of the second pixel area AA2. For example, the first pixel area AA1 and the third pixel area AA3 may be disposed on opposite sides of the second pixel area AA2. For example, the first pixel area AA1 may be located at the upper end of the second pixel area AA2, and the third pixel area AA3 may be located at the lower end of the second pixel area AA2. In this case, the second pixel area AA2 may be disposed between the first pixel area AA1 and the third pixel area AA3.

[0085] In some embodiments, at least two of the pixel areas AA1, AA2, and AA3 may have different sizes. For example, the second pixel area AA2 may be larger than the first pixel area AA1 and / or the third pixel area AA3. For example, the second pixel area AA2 may have the largest size of the pixel area, and the first pixel area AA1 and the third pixel area AA3 may have the same size. However, the present invention is not limited thereto. For example, in another embodiment, all of the pixel areas AA1, AA2, and AA3 may have the same size.

[0086] Additionally, in some embodiments, Figure 2 , the first pixel area AA1, the second pixel area AA2, and the third pixel area AA3 have the same width, but the present invention is not limited thereto. For example, the first pixel area AA1 and / or the third pixel area AA3 may have a shape such that the width of the first pixel area AA1 and / or the third pixel area AA3 gradually decreases in a direction away from the second pixel area AA2. Alternatively, the first pixel area AA1 and / or the third pixel area AA3 may have a fixed width that is smaller than the width of the second pixel area AA2.

[0087] In addition, in some embodiments, at least two of the pixel areas AA1, AA2, and AA3 may have the same width and / or length, or may have different sizes, even if they have the same number of horizontal pixel columns and / or the same number of scan lines. For example, the first pixel area AA1 and the third pixel area AA3 may have the same width and / or length and the same number of horizontal pixel columns and / or the same number of scan lines, but their sizes may be different. For example, even if the first pixel area AA1 and the third pixel area AA3 have substantially the same width and / or length, when a concave portion, an opening, or a dummy area (e.g., an area in which the first pixel PXL1 is not disposed) is located in one of the first pixel areas AA1, the first pixel area AA1 may also be actually smaller than the third pixel area AA3. That is, in the present invention, the shape or size (e.g., width, length, and / or size) of the first pixel area AA1, the second pixel area AA2, and / or the third pixel area AA3 is not specifically limited, and various modifications may be made.

[0088] In some embodiments, the second pixel area AA2 disposed at the central portion of the display area AA may correspond to Figure 1C In addition, the first pixel area AA1 and the third pixel area AA3 disposed at the edge of the display area AA may correspond to Figure 1C The non-visible display area of ​​NVDA is shown.

[0089] For example, when the display device 10 is driven in the second mode, the user does not see the images displayed in the first pixel area AA1 and the third pixel area AA3, and can only see the image displayed in the second display area AA2. In this case, the display device 10 displays a valid image only in the second pixel area AA2. In the present embodiment, when the display device 10 is driven in the second mode, as will be described in detail below, a dummy image (e.g., a predetermined dummy image) may be displayed in the first pixel area AA1 and the third pixel area AA3.

[0090] When the display device 10 is driven in the first mode, the user can see the images displayed in the first pixel area AA1 to the third pixel area AA3. That is, when the display device 10 is driven in the first mode, a valid image can be displayed in the entire display area AA including the first pixel area AA1 to the third pixel area AA3. For example, when the display device 10 is driven in the first mode, the images displayed in the first pixel area AA1 to the third pixel area AA3 can be connected to effectively implement a single screen in the entire display area AA.

[0091] In some embodiments, a plurality of first pixels PXL1 may be disposed in the first pixel area AA1, and a plurality of second pixels PXL2 may be disposed in the second pixel area AA2. In addition, a plurality of third pixels PXL3 may be disposed in the third pixel area AA3.

[0092] The pixels PXL1, PXL2, and PXL3 emit light (eg, light having a predetermined brightness) according to various driving powers and / or driving signals supplied from the driver. To this end, each of the pixels PXL1, PXL2, and PXL3 may include at least one light emitting element (eg, an organic light emitting diode).

[0093] The peripheral area NA may be a non-display area in which no image is displayed. Components for driving the pixels PXL1, PXL2, and PXL3 may be located in the peripheral area NA. For example, wirings, pads, and / or at least one driver may be located in the peripheral area NA.

[0094] In some embodiments, the peripheral area NA may be located around the display area AA to surround at least a portion of the display area AA. For example, the peripheral area NA may be located outside the pixel areas AA1, AA2, and AA3 forming the display area AA to surround the entire display area AA.

[0095] Figure 3 1 shows a display device according to an embodiment of the present invention. In some embodiments, as Figures 1A to 2 As shown in Figure 3 The display device shown in FIG. 1 includes a plurality of pixel regions and may be a display device that is detachable from a wearable device. Figure 3 When the display device of the present embodiment is mounted on a wearable device, the display device can be driven in the second mode so as to display a valid image in some display areas, and when the display device is driven in the second mode so as to display a valid image in some display areas, Figure 3 When the display device of the current embodiment is separated from the wearable device, the display device can be driven in a first mode (in the first mode, a valid image is displayed in the entire display area).

[0096] Reference Figure 3 , the display device according to the present embodiment includes a first scan driver 100 , a second scan driver 200 , a third scan driver 300 , a data driver 400 , a timing controller 500 , and a display area 600 .

[0097] The display area 600 includes at least two pixel areas, for example, the display area 600 may include a first pixel area 602 , a second pixel area 604 , and a third pixel area 606 .

[0098] In some embodiments, the first pixel region 602, the second pixel region 604, and the third pixel region 606 may be sequentially arranged so that the first pixel region 602 and the third pixel region 606 are adjacent to the second pixel region 604. For example, the pixel regions 602, 604, and 606 may be sequentially arranged in the order of the first pixel region 602, the second pixel region 604, and the third pixel region 606 from one side (e.g., the upper end) of the display region 600. In this case, the second pixel region 604 may include a central portion of the display region 600. In addition, the first pixel region 602 may be disposed adjacent to a first horizontal line of the second pixel region 604, and the third pixel region 606 may be disposed adjacent to a last horizontal line of the second pixel region 604. Therefore, the first second scan line S21 among the second scan lines S21 to S2n (n is a natural number of 2 or greater) can be positioned adjacent to the last first scan line S1k among the first scan lines S11 to S1k (k is a natural number of 2 or greater), and the last second scan line S2n among the second scan lines S21 to S2n can be positioned adjacent to the first third scan line S31 among the third scan lines S31 to S3j (j is a natural number of 2 or greater).

[0099] In the present embodiment, the display area 600 can display valid images in different areas according to a plurality of different modes. For example, the display area 600 can display valid images in the entire area including the first pixel area 602 to the third pixel area 606 according to the first mode (e.g., the normal mode). That is, when the display device is driven in the first mode, valid images can be displayed in the first pixel area 602, the second pixel area 604, and the third pixel area 606. For example, when the display device is driven in the first mode, a unified screen can be realized by the first pixel area 602 to the third pixel area 606 connected to each other. In this case, the user can see all images displayed in the first pixel area 602, the second pixel area 604, and the third pixel area 606.

[0100] On the other hand, the display area 600 may display valid images only in some areas according to the second mode (eg, VR mode). For example, when the display device is driven in the second mode, the display area 600 may display valid images only in some areas including the central part (eg, Figure 1A The effective image is displayed in the second pixel area 604 (the central part corresponding to the lens 20 shown in FIG. 1 ), and the dummy image may be displayed in the first pixel area 602 and the third pixel area 606 disposed at the opposite sides of the second pixel area 604. When the display device is driven in the second mode, the dummy image displayed in the first pixel area 602 and the third pixel area 606 may be invisible to the user because the dummy image is Figure 1A The structure is covered by the frame 31 shown in FIG.

[0101] On the other hand, in the comparative embodiment, for the period during which the display device is driven in the second mode, the driving of the first pixel region 602 and the third pixel region 606 is stopped. For example, when the display device is driven in the second mode, the scan signal is not supplied to the scan lines S11 to S1k connected to the first pixel PXL1, nor is it supplied to the scan lines S31 to S3j connected to the third pixel PXL3. In this case, the data signal is not supplied to the first pixel PXL1 and the third pixel PXL3.

[0102] However, as described above, when the data signal is not provided to the first pixel PXL1 and the third pixel PXL3 according to a specific mode (e.g., the second mode), a characteristic deviation may occur between the driving transistors included in the first pixel PXL1 and the third pixel PXL3 and the driving transistor included in the second pixel PXL2 (disposed in the second pixel region 604). Therefore, when the driving mode of the display device is switched from the second mode to the first mode, a luminance deviation may occur for each of the pixel regions 602, 604, and 606. Such a luminance deviation may cause the boundary lines between the pixel regions 602, 604, and 606 to appear inside the display region 600, and the pixel regions 602, 604, and 606 may be recognized as stains in the form of blocks by the user, for example.

[0103] On the contrary, in the present embodiment, even when the display device is driven in the second mode, the first pixel region 602 and the third pixel region 606 are driven so that an image (e.g., a predetermined image or a dummy image) is displayed. Therefore, it is possible to reduce or prevent the characteristic deviation of the pixels PXL1, PXL2, and PXL3 (e.g., the characteristic deviation of the driving transistor) from occurring between the pixel regions 602, 604, and 606. Therefore, according to the present embodiment, when the display device is driven in the first mode, the pixel regions 602, 604, and 606 are not recognized as stains in the form of blocks by the user, thereby improving the display quality.

[0104] A plurality of first pixels PXL1 are disposed in the first pixel region 602. The first pixels PXL1 are connected to first scan lines S11 to S1k and data lines D1 to Dm, respectively. In some embodiments, the first scan lines S11 to S1k may be disposed in the first pixel region 602 to extend in a first direction (e.g., in a horizontal direction). In some embodiments, the data lines D1 to Dm may be disposed in the display region 600 to intersect the first scan lines S11 to S1k, the second scan lines S21 to S2n, and the third scan lines S31 to S3j along a second direction (e.g., in a vertical direction) intersecting the first direction.

[0105] When the first scan signal is supplied to the corresponding first scan line among the first scan lines S11 to S1k, the first pixel PXL1 is selected and receives the data signal from the data lines D1 to Dm. After receiving the data signal, the first pixel PXL1 emits light having brightness corresponding to the data signal while controlling a driving current flowing from the first power source ELVDD to the second power source ELVSS via the organic light emitting diode.

[0106] A plurality of second pixels PXL2 are disposed in the second pixel region 604. The second pixels PXL2 are connected to the second scan lines S21 to S2n and the data lines D1 to Dm. In some embodiments, the second scan lines S21 to S2n are disposed in the second pixel region 604 to extend along a first direction (e.g., a horizontal direction) and may intersect with the data lines D1 to Dm. In some embodiments, the number of the second scan lines S21 to S2n in the second pixel region 604 may be greater than the number of the first scan lines S11 to S1k in the first pixel region 602 and / or the number of the third scan lines S31 to S3j in the third pixel region 606, but the second scan lines S21 to S2n are not limited thereto.

[0107] When the second scan signal is supplied to the corresponding second scan line among the second scan lines S21 to S2n, the second pixel PXL2 is selected and receives the data signal from the data lines D1 to Dm. After receiving the data signal, the second pixel PXL2 emits light having brightness corresponding to the data signal while controlling a driving current flowing from the first power source ELVDD to the second power source ELVSS via the organic light emitting diode.

[0108] A plurality of third pixels PXL3 are disposed in the third pixel region 606. The third pixels PXL3 are connected to the third scan lines S31 to S3j and the data lines D1 to Dm. In some embodiments, the third scan lines S31 to S3j are disposed in the third pixel region 606 to extend in a first direction (eg, a horizontal direction) and may intersect the data lines D1 to Dm.

[0109] When the third scan signal is supplied to the corresponding third scan line among the third scan lines S31 to S3j, the third pixel PXL3 is selected and receives the data signal from the data lines D1 to Dm. After receiving the data signal, the third pixel PXL3 emits light having brightness corresponding to the data signal while controlling a driving current flowing from the first power source ELVDD to the second power source ELVSS via the organic light emitting diode.

[0110] In the present embodiment, the first to third pixels PXL1 to PXL3 may be implemented as circuits having various forms. For example, the first to third pixels PXL1 to PXL3 may include various pixel circuits including a driving transistor.

[0111] Furthermore, the number of first scan lines S11 to S1k located in the first pixel region 602 , second scan lines S21 to S2n located in the second pixel region 604 , and / or third scan lines S31 to S3j located in the third pixel region 606 may be variously modified.

[0112] For example, the number of the first scan lines S11 to S1k may be set to two or more in consideration of the overlap area with the frame 31 of the wearable device 30. For example, one hundred or more first scan lines S11 to S1k may be located in the first pixel region 602. Similarly, the number of the third scan lines S31 to S3j may be set to two or more in consideration of the overlap area with the frame 31 of the wearable device 30. For example, one hundred or more third scan lines S31 to S3j may be located in the third pixel region 606. The first scan driver 100 supplies a first scan signal to the first scan lines S11 to S1k to drive the first scan lines S11 to S1k. When the first scan signal is supplied to the first scan lines S11 to S1k, the first pixels PXL1 are sequentially selected in units of horizontal lines. To this end, the first scan signal is set to a gate-on voltage capable of turning on a transistor (e.g., a switching transistor) included in the first pixel PXL1.

[0113] The second scan driver 200 supplies the second scan signal to the second scan lines S21 to S2n to drive the second scan lines S21 to S2n. When the second scan signal is supplied to the second scan lines S21 to S2n, the second pixels PXL2 are sequentially selected in units of horizontal lines. To this end, the second scan signal is set to a gate-on voltage capable of turning on a transistor (e.g., a switching transistor) included in the second pixel PXL2.

[0114] The third scan driver 300 supplies a third scan signal to the third scan lines S31 to S3j to drive the third scan lines S31 to S3j. When the third scan signal is supplied to the third scan lines S31 to S3j, the third pixels PXL3 are sequentially selected in units of horizontal lines. To this end, the third scan signal is set to a gate-on voltage capable of turning on a transistor (e.g., a switching transistor) included in the third pixel PXL3.

[0115] The data driver 400 receives the data control signal DCS and the image data DATA from the timing controller 500. The data driver 400 generates data signals according to the data control signal DCS and the image data DATA, and supplies the generated data signals to the data lines D1 to Dm.

[0116] When the display device is driven in the first mode, the first scan driver 100, the second scan driver 200, and the third scan driver 300 may sequentially supply the first scan signal, the second scan signal, and the third scan signal. Then, the data signal from the data driver 400 is sequentially supplied to the corresponding pixels among the first pixel PXL1, the second pixel PXL2, and the third pixel PXL3, and thus, a predetermined effective image may be displayed in the entire display area 600.

[0117] On the other hand, when the display device is driven in the second mode, the second scan driver 200 may sequentially supply the second scan signal. Then, the data signal from the data driver 400 is sequentially supplied to the second pixel PXL2, and thus a predetermined effective image may be displayed in the second pixel region 604.

[0118] However, in the present embodiment, when the display device is driven in the second mode, the third scan driver 300 may sequentially supply the third scan signal for some period (e.g., the first period) during which the second scan signal is sequentially supplied. Then, the data signal from the data driver 400 is supplied not only to the second pixel PXL2 of the corresponding horizontal line, but also to the third pixel PXL3 disposed in the determined horizontal line of the third pixel region 606. Therefore, a dummy image corresponding to one region (e.g., the top region) of the effective image is displayed in the third pixel region 606.

[0119] In addition, when the display device is driven in the second mode, the first scan driver 100 may sequentially supply the first scan signal for the remaining period (e.g., the second period after the first period), during which the second scan signal is sequentially supplied. Then, the data signal from the data driver 400 is supplied not only to the second pixel PXL2 of the corresponding horizontal line, but also to the first pixel PXL1 disposed in the determined horizontal line of the first pixel area 602. Therefore, a dummy image corresponding to another area (e.g., the bottom area) of the effective image is displayed in the first pixel area 602.

[0120] As described above, in the present embodiment, when the display device is driven in the second mode, the first pixel PXL1 and the third pixel PXL3 are also driven to display a dummy image in the first pixel region 602 and the third pixel region 606. Therefore, while ensuring the time required for driving, it is possible to reduce or prevent the characteristics of the driving transistors included in the pixels PXL1, PXL2, and PXL3 from being set differently between the pixel regions 602, 604, and 606. Therefore, when the driving mode of the display device is switched from the second mode to the first mode, it is possible to reduce or prevent the generation of a brightness deviation between the pixel regions 602, 604, and 606, so that no boundary line appears between the pixel regions 602, 604, and 606 in the display region 600.

[0121] The timing controller 500 generates clock signals CLK1 and CLK2, start signals FLM1, FLM2 and FLM3, and a data control signal DCS based on an externally supplied timing signal. The clock signals CLK1 and CLK2 generated by the timing controller 500 are supplied to the first scan driver 100, the second scan driver 200, and the third scan driver 300. In addition, the first start signal FLM1 generated by the timing controller 500 is supplied to the first scan driver 100, the second start signal FLM2 generated by the timing controller 500 is supplied to the second scan driver 200, and the third start signal FLM3 generated by the timing controller 500 is supplied to the third scan driver 300. In addition, the data control signal DCS generated by the timing controller 500 is supplied to the data driver 400.

[0122] The first start signal FLM1 controls the supply timing of the first scan signal. The clock signals CLK1 and CLK2 supplied to the first scan driver 100 are used to shift the first start signal FLM1.

[0123] The second start signal FLM2 controls the supply timing of the second scan signal. The clock signals CLK1 and CLK2 supplied to the second scan driver 200 are used to shift the second start signal FLM2.

[0124] The third start signal FLM3 controls the supply timing of the third scan signal. The clock signals CLK1 and CLK2 supplied to the third scan driver 300 are used to shift the third start signal FLM3.

[0125] The data control signal DCS includes a source start signal, a source output enable signal and a source sampling clock. The source start signal controls the data sampling start point of the data driver 400. The source sampling clock controls the sampling operation of the data driver 400 based on the rising time or falling time. The source output enable signal controls the output timing of the data driver 400.

[0126] In addition, the timing controller 500 rearranges the image data DATA and then transmits it to the data driver 400. For example, the timing controller 500 converts the image data DATA according to the first mode or the second mode so that the image data DATA is suitable for an area (e.g., a predetermined area) in which a valid image is to be displayed, and may transmit the image data DATA to the data driver 400. Alternatively, the timing controller 500 may receive the image data DATA suitable for the area in which a valid image is to be displayed from the host system, and rearrange the image data DATA to transmit it to the data driver 400. Then, the data driver 400 generates a data signal corresponding to the image data DATA supplied from the timing controller 500.

[0127] As described above, when driven in the second mode, the display device according to the present embodiment displays dummy images in the first pixel region 602 and the third pixel region 606, the dummy images corresponding to respective regions or one region of the effective image to be displayed in the second pixel region 604. For example, for a period during which the display device is driven in the second mode, the first pixel region 602 and the third pixel region 606 located on opposite sides of the second pixel region 604 may display corresponding images, which are displayed at opposite ends of the effective image (the image displayed in the second pixel region 604).

[0128] According to the present embodiment, image sticking that would otherwise occur in the boundary area between the visible display area VDA (e.g., the second pixel area 604) and the non-visible display area NVDA (e.g., the first pixel area 602 and the third pixel area 606) can be reduced or minimized, and light leakage interference can be reduced or prevented. A detailed description of this will be described below.

[0129] Figure 4 Shows Figure 3 For ease of description, the pixel is shown in FIG. Figure 4 , any pixel among the first to third pixels PXL1 to PXL3 connected to the i-th (i is a natural number) data line Di and the i-th scan line Si (eg, any one of the first scan lines S11 to S1k, the second scan lines S21 to S2n, and the third scan lines S31 to S3j).

[0130] Reference Figure 4 According to the present embodiment, the pixels PXL1 , PXL2 and PXL3 include an organic light emitting diode OLED and a pixel circuit 610 , and the pixel circuit 610 is used to control a driving current supplied to the organic light emitting diode OLED.

[0131] An anode of the organic light emitting diode OLED is connected to the pixel circuit 610 , while a cathode of the organic light emitting diode OLED is connected to the second power source ELVSS. The organic light emitting diode OLED generates light (eg, light having a predetermined brightness) according to the amount of driving current supplied from the pixel circuit 610 .

[0132] The pixel circuit 610 controls the amount of driving current flowing from the first power source ELVDD to the second power source ELVSS via the organic light emitting diode OLED according to the data signal. To this end, the pixel circuit 610 includes a first transistor T1 and a second transistor T2.

[0133] The first transistor T1 (driving transistor) is connected between the first power source ELVDD and the anode of the organic light emitting diode OLED. In addition, the gate electrode of the first transistor T1 is connected to the first node N1. The first transistor T1 controls the amount of driving current flowing from the first power source ELVDD to the second power source ELVSS via the organic light emitting diode OLED according to the voltage of the first node N1.

[0134] The second transistor T2 is connected between the i-th data line Di and the first node N1. In addition, the gate electrode of the second transistor T2 is connected to the scan line Si. When the scan signal is supplied to the scan line Si, the second transistor T2 is turned on and electrically couples the i-th data line Di and the first node N1.

[0135] The storage capacitor Cst is connected between the first power source ELVDD and the first node N1. The storage capacitor Cst stores a voltage corresponding to the data signal.

[0136] The steps of driving the pixels PXL1, PXL2, and PXL3 will be described. First, a scan signal is supplied to the scan line Si to turn on the second transistor T2. When the second transistor T2 is turned on, a data signal is supplied from the i-th data line Di to the first node N1. In this case, the storage capacitor Cst stores a voltage corresponding to the data signal. After the voltage corresponding to the data signal is stored in the storage capacitor Cst, the second transistor T2 is turned off.

[0137] Subsequently, the first transistor T1 controls the amount of driving current flowing from the first power source ELVDD to the second power source ELVSS via the organic light emitting diode OLED according to the voltage of the first node N1. Then, the organic light emitting diode OLED generates light having a brightness corresponding to the amount of driving current. When a data signal corresponding to a black grayscale is supplied to the first node N1, the first transistor T1 reduces or blocks the driving current from being supplied to the organic light emitting diode OLED. In this case, the organic light emitting diode OLED does not emit light, thereby displaying a black grayscale.

[0138] The pixels PXL1, PXL2, and PXL3 repeat the above steps to display an image (eg, a predetermined image) in the display area 600. In addition, in the present embodiment, the circuit structure of the pixels PXL1, PXL2, and PXL3 is not limited to Figure 4 For example, the pixels PXL1, PXL2, and PXL3 may include various forms of pixel circuits.

[0139] Figure 5 Shows Figure 3 An embodiment of a scan driver is shown in FIG. Figure 5 In the embodiment, the scan driver is driven by two clock signals, but the present invention is not limited thereto. That is, the number and / or type of the clock signals may be changed.

[0140] Reference Figure 5 The first scan driver 100 according to the present embodiment includes first scan stages SST11 to SST1k connected to the first scan lines S11 to S1k, respectively. In some embodiments, the number of first scan stages SST11 to SST1k may be variously modified according to the number of horizontal lines disposed in the first pixel region 602.

[0141] The first scanning stages SST11 to SST1k receive the first start signal FLM1 and the clock signals CLK1 and CLK2, and sequentially supply the first scanning signals to the first scanning lines S11 to S1k according to the first start signal FLM1. For example, the first first scanning stage SST11 may supply the first scanning signal to the first first scanning line S11 according to the first start signal FLM1. In addition, the remaining first scanning stages (SST12 to SST1k) may provide the first scanning signals to the corresponding first scanning lines (any one of S12 to S1k) according to the output signals of the respective previous stages (e.g., the first scanning signals of the previous stages). That is, the supply timing of the first scanning signal supplied to each of the first scanning lines S11 to S1k may be determined according to the supply timing of the first start signal FLM1.

[0142] In some embodiments, the second scan driver 200 includes second scan stages SST21 to SST2n respectively connected to the second scan lines S21 to S2n. The second scan stages SST21 to SST2n receive the second start signal FLM2 and the clock signals CLK1 and CLK2, and sequentially supply the second scan signals to the second scan lines S21 to S2n according to the second start signal FLM2. For example, the first second scan stage SST21 may supply the second scan signal to the first second scan line S21 according to the second start signal FLM2. In addition, the remaining second scan stages SST22 to SST2n may provide the second scan signals to the corresponding second scan lines (any one of S22 to S2n) among the second scan lines connected to the remaining second scan stages SST22 to SST2n according to the output signals of the respective previous stages (e.g., the second scan signals of the previous stages). That is, the supply timing of the second scan signal supplied to each of the second scan lines S21 to S2n may be determined according to the supply timing of the second start signal FLM2.

[0143] In some embodiments, the third scan driver 300 includes third scan stages SST31 to SST3j respectively connected to the third scan lines S31 to S3j. In some embodiments, the number of third scan stages SST31 to SST3j may be variously modified according to the number of horizontal lines disposed in the third pixel region 606.

[0144] The third scanning stages SST31 to SST3j receive the third start signal FLM3 and the clock signals CLK1 and CLK2, and sequentially supply the third scanning signals to the corresponding third scanning lines among the third scanning lines S31 to S3j according to the third start signal FLM3. For example, the first third scanning stage SST31 may supply the third scanning signal to the first third scanning line S31 according to the third start signal FLM3. In addition, the remaining third scanning stages (SST32 to SST3j) may provide the third scanning signals to the corresponding third scanning lines (any one of SS32 to SS3j) according to the output signals of the respective previous stages (for example, the third scanning signals of the previous stages). That is, the supply timings of the third scanning signals respectively supplied to the third scanning lines S31 to S3j may be determined according to the supply timing of the third start signal FLM3.

[0145] In the present embodiment, the configuration of the scanning stages SST11 to SST1k, SST21 to SST2n, and SST31 to SST3j is not particularly limited. That is, the scanning stages SST11 to SST1k, SST21 to SST2n, and SST31 to SST3j may be implemented in various forms of scan driving circuits.

[0146] Figure 6When driven in the first mode Figure 3 The display device shown in FIG. 1 is an embodiment of the driving timing of the scan driver. For example, Figure 6 An embodiment of a start signal input to a scan driver according to a first mode and a scan signal output from the scan driver according to the start signal is shown. In addition, Figure 7 Schematically shows when driving in the first mode Figure 3 The display device shown in FIG. 1 is a display region supplying a scanning signal in a supply order. Figure 8 When driven in the first mode Figure 3 The display device shown in FIG. 1 is an embodiment of an image displayed in a display area.

[0147] Reference Figure 6 , when the display device is driven in the first mode, the timing controller 500 sequentially supplies the first start signal FLM1 to the first scan driver 100, the second start signal FLM2 to the second scan driver 200, and the third start signal FLM3 to the third scan driver 300. In this case, the supply timing of the first start signal FLM1, the second start signal FLM2, and the third start signal FLM3 is set so that the first scan signal, the second scan signal, and the third scan signal are sequentially supplied to the first scan lines S11 to S1k, the second scan lines S21 to S2n, and the third scan lines S31 to S3j. In some embodiments, the first start signal FLM1, the second start signal FLM2, and the third start signal FLM3 may have the same width, and the width may be changed.

[0148] When the first start signal FLM1 is provided, the first scan driver 100 supplies the first first scan signal to the first first scan line S11 according to the clock signals CLK1 and CLK2. For example, the first scan driver 100 may shift the first start signal FLM1 according to the clock signals CLK1 and CLK2 to supply the first first scan signal to the first first scan line S11. In addition, the first scan driver 100 may shift the first first scan signal to supply the second first scan signal to the second first scan line S12. In the foregoing manner, the first scan driver 100 sequentially supplies the first scan signal to the first scan lines S11 to S1k. Then, the data signals DS1 to DSk from the data driver 400 are supplied to the first pixel area 602. Therefore, an image (e.g., a predetermined image) corresponding to the data signals DS1 to DSk is displayed in the first pixel area 602.

[0149] When the second start signal FLM2 is provided, the second scan driver 200 supplies the first second scan signal to the first second scan line S21 according to the clock signals CLK1 and CLK2. For example, the second scan driver 200 shifts the second start signal FLM2 according to the clock signals CLK1 and CLK2 to supply the first second scan signal to the first second scan line S21. In addition, the second scan driver 200 may shift the first second scan signal to supply the second second scan signal to the second second scan line S22. In the aforementioned manner, the second scan driver 200 sequentially supplies the second scan signal to the second scan lines S21 to S2n. Then, the data signals DSk+1 to DSk+n from the data driver 400 are supplied to the second pixel area 604, and thus, an image (e.g., a predetermined image) corresponding to the data signals DSk+1 to DSk+n is displayed in the second pixel area 604.

[0150] When the third start signal FLM3 is provided, the third scan driver 300 supplies the first third scan signal to the first third scan line S31 according to the clock signals CLK1 and CLK2. For example, the third scan driver 300 may shift the third start signal FLM3 according to the clock signals CLK1 and CLK2 to supply the first third scan signal to the first third scan line S31. In addition, the third scan driver 300 may shift the first third scan signal to supply the second third scan signal to the second third scan line S32. In the aforementioned manner, the third scan driver 300 sequentially supplies the third scan signal to the third scan lines S31 to S3j. Then, the data signals DSk+n+1 to DSk+n+j from the data driver 400 are supplied to the third pixel area 606, and thus, an image (e.g., a predetermined image) corresponding to the data signals DSk+n+1 to DSk+n+j is displayed in the third pixel area 606.

[0151] When the display device is driven in the first mode, the first scan driver 100, the second scan driver 200, and the third scan driver 300 repeat the above steps, thereby sequentially supplying scan signals to all of the scan lines S11 to S1k, S21 to S2n, and S31 to S3j of the display area 600. That is, when the display device is driven in the first mode, the first scan driver 100, the second scan driver 200, and the third scan driver 300 sequentially drive the first scan lines S11 to S1k, the second scan lines S21 to S2n, and the third scan lines S31 to S3j, respectively.

[0152] Therefore, if Figure 7As shown in FIG. 6 , the scan signal is sequentially supplied to the first pixel region 602, the second pixel region 604, and the third pixel region 606. For example, for one frame period realizing one screen, the first pixel PXL1, the second pixel PXL2, and the third pixel PXL3 of each horizontal line may be sequentially selected in the order of the first pixel region 602, the second pixel region 604, and the third pixel region 606 to receive the data signal.

[0153] As described above, when the display device is driven in the first mode, a valid image can be displayed in the entire display area 600 of the display device. Figure 8 As shown in FIG. 6 , a valid image may be displayed collectively in all of the first pixel region 602, the second pixel region 604, and the third pixel region 606 forming the display region 600. For example, images displayed in the first pixel region 602, the second pixel region 604, and the third pixel region 606 may be connected to implement a single connected screen.

[0154] In some embodiments, when the display device is mounted on the wearable device 30, the first mode may be deactivated, and conversely, the first mode may be activated. That is, when the display device is separated from the wearable device 30, the display device may be driven in the first mode.

[0155] Fig. 9 When driven in the second mode Figure 3 The display device shown in FIG. 1 is an embodiment of the driving timing of the scan driver. For example, Fig. 9 An embodiment of a start signal input to the scan driver according to the second mode and a scan signal output from the scan driver according to the start signal is shown. In addition, Fig.10 Schematically shows when driving in the second mode Figure 3 The order in which the scanning signals are supplied to the display area when the display device is in the display device, Fig.11 When driven in the second mode Figure 3 The display device shown in FIG. 1 is an embodiment of an image displayed in a display area.

[0156] Reference Fig. 9, when the display device is driven in the second mode, the timing controller 500 supplies (for example, in a predetermined order) the first start signal FLM1 to the first scan driver 100, the second start signal FLM2 to the second scan driver 200, and the third start signal FLM3 to the third scan driver 300. In this case, the supply timings of the first start signal FLM1, the second start signal FLM2, and the third start signal FLM3 are set so that the first scan lines S11 to S1k and the third scan lines S31 to S3j are driven for different periods during which the second scan lines S21 to S2n are sequentially driven.

[0157] Specifically, in the present embodiment, when the display device is driven in the second mode, the supply timing of the first start signal FLM1, the second start signal FLM2, and the third start signal FLM3 may be set so that a dummy image is displayed in the first pixel region 602, and another dummy image is displayed in the third pixel region 606, the dummy image corresponding to an image of an area adjacent to the third pixel region 606 and may be a part of the effective image displayed in the second pixel region 604, and the other dummy image corresponding to an image of an area adjacent to the first pixel region 602 and may be another part of the effective image. To this end, the timing controller 500 may supply the second start signal FLM2 and the third start signal FLM3 to the second scan driver 200 and the third scan driver 300 in parallel or simultaneously for each frame period according to the second mode, and may supply the first start signal FLM1 to the first scan driver 100 after completing the driving of the third scan lines S31 to S3j.

[0158] For example, according to the second mode, for a first period P1 (e.g., an initial period) during which the second scan driver 200 sequentially drives some of the second scan lines S21 to S2n, the third scan driver 300 may sequentially drive the third scan lines S31 to S3j. In addition, for a second period P2 (e.g., a period immediately following the first period P1) after the driving of the third scan lines S31 to S3j is completed, the first scan driver 100 may sequentially drive the first scan lines S11 to S1k.

[0159] According to the second mode, the second scan driver 200 may drive at least some of the second scan lines S21 to S2n adjacent to the first pixel region 602 (e.g., some of the second scan lines S21 to S2n) for a first period P1. In addition, according to the second mode, the second scan driver 200 may drive at least some of the second scan lines S21 to S2n adjacent to the third pixel region 606 (e.g., other of the second scan lines S21 to S2n) for a second period P2. That is, when the display device is driven in the second mode, some of the second scan signals supplied to the second scan lines S21 to S2n may overlap with the third scan signals supplied to the third scan lines S31 to S3j. In addition, other of the second scan signals supplied to the second scan lines S21 to S2n may overlap with the first scan signals supplied to the first scan lines S11 to S1k.

[0160] In some embodiments, the supply timing of the first start signal FLM1 may depend on the number of the first scan lines S11 to S1k and the second scan lines S21 to S2n. For example, when k first scan lines S11 to S1k are arranged in the first pixel region 602 on the second pixel region 604, the k first scan lines S11 to S1k are set to have the supply timing of the first start signal FLM1, so that the k first scan lines S11 to S1k are driven in parallel or simultaneously with the k second scan lines S2(n-k+1) to S2n disposed at the lower end of the second pixel region 604. For example, when k first scan lines S11 to S1k and n (n is a natural number of k or greater) second scan lines S21 to S2n are respectively arranged in the first pixel area 602 and the second pixel area 604, the supply timing of the first start signal FLM1 can be set so that the first scan driver 100 and the second scan driver 200 supply scan signals to the first first scan line S11 and the n-k+1th second scan line S2 (n-k+1) in parallel or simultaneously according to the second mode.

[0161] After receiving the second start signal FLM2 and the third start signal FLM3 in parallel or simultaneously, the second scan driver 200 and the third scan driver 300 output scan signals to the first second scan line S21 and the first third scan line S31, respectively, according to the second start signal FLM2 and the third start signal FLM3. That is, according to the second mode, the second scan driver 200 and the third scan driver 300 may supply scan signals to the first second scan line S21 and the first third scan line S31 in parallel or simultaneously. After completing the driving of the third scan lines S31 to S3j, the first scan driver 100 may output scan signals to the first first scan line S11 according to the first start signal FLM1 after receiving the first start signal FLM1 from the timing controller 500. In addition, when the second scan driver 200 outputs scan signals to the last second scan line S2n, the first scan driver 100 may output scan signals to the last first scan line S1k. That is, the first scan driver 100 and the second scan driver 200 may supply scan signals to the last first scan line S1 k and the last second scan line S2 n in parallel or simultaneously, respectively.

[0162] That is, in this embodiment, according to the second mode, the second scan driver 200 sequentially drives the second scan lines S21 to S2n, and the first scan driver 100 and the third scan driver 300 respectively drive the first scan lines S11 to S1k and the third scan lines S31 to S3j for different time periods, during which the second scan lines S21 to S2n are driven.

[0163] When the second start signal FLM2 is supplied for each frame period during which the second mode is performed, the second scan driver 200 sequentially supplies the second scan signals to the second scan lines S21 to S2n, and the data driver 400 outputs the data signals DS1 to DSn corresponding to the effective image to be displayed in the second pixel area 604 according to the driving timing of the second scan driver 200. The data signals DS1 to DSn are supplied to the second pixel area 604 according to each second scan signal. Therefore, the effective image corresponding to the data signals DS1 to DSn is displayed in the second pixel area 604.

[0164] In the present embodiment, when the display device is driven in the second mode, some of the data signals DS1 to DSn output from the data driver 400 may be supplied in parallel or simultaneously to the second pixel region 604 and the third pixel region 606, or some of the data signals DS1 to DSn output from the data driver 400 may be supplied in parallel or simultaneously to the first pixel region 602 and the second pixel region 604. For example, when the display device is driven in the second mode, the same data signal DS1 may be supplied to the second pixel PXL2 disposed in the first horizontal line of the second pixel region 604 and the third pixel PXL3 disposed in the first horizontal line of the third pixel region 606. In addition, the same data signal DSn may be supplied to the first pixel PXL1 disposed in the last horizontal line (e.g., the kth horizontal line) of the first pixel region 602 and the second pixel PXL2 disposed in the last horizontal line of the second pixel region 604.

[0165] When the display device is driven in the second mode, the first scan driver 100, the second scan driver 200, and the third scan driver 300 repeat the aforementioned steps and supply scan signals to the scan lines S11 to S1k, S21 to S2n, and S31 to S3j. That is, when the display device is driven in the second mode, as shown in FIG. Fig.10 As shown in , the second scan lines S21 to S2n are sequentially driven for one frame period. In addition, the third scan lines S31 to S3j are sequentially driven for an initial first period P1 (during the first period P1, some of the second scan lines S21 to S2n are driven), and the first scan lines S11 to S1k are sequentially driven for a subsequent second period P2 (during the second period P2, other ones of the second scan lines S21 to S2n are driven).

[0166] In some embodiments, when the display device is driven in the second mode, valid images are displayed only in some display areas of the entire display area 600. Fig.11 As shown in , according to the second mode, a valid image is displayed only in the second pixel region 604 of the display area 600 , while dummy images corresponding to different regions of the valid image can be displayed in the first pixel region 602 and the third pixel region 606 .

[0167] In particular, as described above, according to the present embodiment, when the display device is driven in the second mode, during the first period P1 during which j second scan lines S21 to S2j adjacent to the first pixel region 602 among the second scan lines S21 to S2n (arranged in the second pixel region 604) are driven, j third scan lines S31 to S3j arranged in the third pixel region 606 are also driven. Therefore, the third pixel region 606 receives the data signal input to the second pixel PXL2 connected to the first second scan line S21 to the jth second scan line S2j, and displays the same image as the image displayed by the corresponding second pixel PXL2. In addition, when the display device is driven in the second mode, during the second period P2 during which k second scan lines S2(n-k+1) to S2n adjacent to the third pixel region 606 among the second scan lines S21 to S2n (arranged in the second pixel region 604) are driven, k first scan lines S11 to S1k arranged in the first pixel region 602 are also driven. Therefore, the first pixel area 602 receives the data signal input to the second pixels PXL2 connected to the n-k+1th second scan line S2(n-k+1) to the last n-th second scan line S2n, and displays the same image as the image displayed by the corresponding second pixels PXL2.

[0168] In some embodiments, the second mode may be activated when the display device is mounted on the wearable device 30. In this case, the first pixel area 602 and the third pixel area 606 are covered by the frame 31 of the wearable device 30 and thus become a non-visible display area NVDA, while at least some of the second pixel area 604 becomes or remains a visible display area VDA that is visible to the user.

[0169] In addition, in some embodiments, when the display device is driven in the second mode, the effective image displayed in the second pixel region 604 may be divided into a plurality of images. Figures 1A to 1C As shown in , when the display device is mounted on a wearable device 30 including a left-eye lens 21 and a right-eye lens 22 to be driven, the second pixel area 604 is divided into a plurality of areas according to each of the left-eye lens 21 and the right-eye lens 22, and a valid image (e.g., a predetermined valid image) can be displayed in each divided area.

[0170] For example, the second pixel area 604 may be divided into a plurality of areas to include a predetermined left eye area 6041 in which a left eye image is displayed and a predetermined right eye area 6042 in which a right eye image is displayed. In addition, in some embodiments, the second pixel area 604 may further include a boundary area 6043, which is disposed outside the left eye area 6041 and the right eye area 6042. For example, the boundary area 6043 may be disposed between the left eye area 6041 and the right eye area 6042, between the left eye area 6041 and the first pixel area 602, and between the right eye area 6042 and the third pixel area 606. In some embodiments, the boundary area 6043 may not be recognized by the user because it is shielded by the frame 31 of the wearable device 30, etc.

[0171] In some embodiments, when the display device is driven in the second mode, the boundary area 6043 may display a black grayscale. Alternatively, in another embodiment, the boundary area 6043 may also display a grayscale that changes gradually in a gradient form.

[0172] When the display device is driven in the second mode, the data driver 400 may supply a data signal corresponding to a left-eye image according to the left-eye area 6041, and may supply a data signal corresponding to a right-eye image according to the right-eye area 6042. In addition, when the left-eye area 6041 is disposed relatively close to the first pixel area 602 and the right-eye area 6042 is disposed relatively close to the third pixel area 606, at least some of the data signals corresponding to the left-eye image may be supplied to the third pixel area 606, and at least some of the data signals corresponding to the right-eye image may be supplied to the first pixel area 602.

[0173] In addition, when the display device is driven in the second mode, the data driver 400 may supply a data signal corresponding to a black grayscale to the boundary area 6043. That is, for the second pixel area 604, a data signal corresponding to a black grayscale may be supplied to the boundary area 6043 between the left eye area 6041 and the right eye area 6042, and a data signal corresponding to a black grayscale may be supplied to the boundary area 6043 outside the left eye area 6041 and the right eye area 6042. Therefore, a data signal corresponding to a black grayscale may be supplied to the boundary area between the pixel areas 602, 604, and 606 and to the boundary area 6043 included in the second pixel area 604. Alternatively, in another embodiment, a data signal corresponding to a grayscale that gradually changes in a gradient form may also be supplied to each boundary area 6043.

[0174] Alternatively, in another embodiment of the present invention, the left eye area 6041 and the right eye area 6042 are not separated, and the second pixel area 604 can be integrally formed into a visual display area VDA. In this case, the boundary area 6043 can be set in the boundary area 6043 between the corresponding pixel areas 602, 604 and 606 (for example, the boundary between the first pixel area 602 and the second pixel area 604 and the boundary between the second pixel area 604 and the third pixel area 606).

[0175] According to the present embodiment described above, when the display device is driven in the second mode, a data signal corresponding to a black grayscale (or a grayscale that changes gradually in a gradient form) is supplied to at least a boundary region between the pixel regions 602, 604, and 606 (e.g., a boundary line located between the pixel regions 602, 604, and 606, and an edge of each of the pixel regions 602, 604, and 606, respectively). In this case, the same data signal (e.g., a data signal of a black grayscale) as the data signal supplied to the last horizontal line of the second pixel region 604 may be supplied to the last horizontal line of the first pixel region 602. In addition, the same data signal (e.g., a data signal of a black grayscale) as the data signal supplied to the first horizontal line of the second pixel region 604 may also be supplied to the first horizontal line of the third pixel region 606.

[0176] Therefore, according to the present embodiment, no sharp image change occurs in the boundary region between the pixel regions 602, 604, and 606, and image sticking at the interface can be reduced or prevented (e.g., the occurrence of the image sticking phenomenon can be reduced or prevented). In addition, since the black grayscale is displayed at the edge of the first pixel region 602 and the third pixel region 606 adjacent to the second pixel region 604, light leakage interference caused by the first pixel region 602 and the third pixel region 606 can be reduced or prevented.

[0177] In addition, according to the present embodiment, when the display device is driven in the second mode, the scan signal is supplied not only to the second scan lines S21 to S2n of the second pixel area 604 (set as the visible display area VDA), but also to the scan lines S11 to S1k and S31 to S3j of the first pixel area 602 and the third pixel area 606 (set as the non-visible display area NVDA), thereby driving all the pixels of the first pixel PXL1 to the third pixel PXL3. According to the present embodiment, in the visible display area VDA and the non-visible display area NVDA, the driving transistors (for example, Figure 4 The characteristics of the first transistor T1 in the display device are set differently, and thus the display quality of the display device can be improved.

[0178] In addition, according to the present embodiment, when the display device is driven in the second mode, the first scan lines S11 to S1k and the third scan lines S31 to S3j are driven for at least some of the periods during which the second scan lines S21 to S2n are driven. Therefore, the time required for driving the display area 600 can be sufficiently ensured.

[0179] Fig.12 FIG. 2 shows a display device according to an embodiment of the present invention. Fig.12 In the drawings, the same reference numerals are used to indicate Figure 3 The same or similar elements will be described below and their repeated detailed description will be omitted.

[0180] Reference Fig.12 In the display device according to the present embodiment, the scan drivers 100, 200 and 300 may be arranged at opposite sides of the display area 600. For example, the display device according to the present embodiment may include two first scan drivers 100, two second scan drivers 200 and two third scan drivers 300, with each side of the display area 600 having one scan driver of each type of scan driver. In some embodiments, any one of the first scan drivers 100, any one of the second scan drivers 200 and any one of the third scan drivers 300 is located at one side of the display area 600, while another one of the first scan drivers 100, another one of the second scan drivers 200 and another one of the third scan drivers 300 may be located at the other side of the display area 600. According to the present embodiment, each of the scan lines S11 to S1k, S21 to S2n and S31 to S3j may receive scan signals from their opposite ends.

[0181] Fig.13 FIG. 2 shows a display device according to an embodiment of the present invention. Fig.13 In the drawings, the same reference numerals are used to indicate Figure 3 The components are the same or similar components, and their repeated detailed descriptions will be omitted.

[0182] Reference Fig.13 The display device according to the present embodiment further includes first emission control lines E11 to E1k, second emission control lines E21 to E2n, third emission control lines E31 to E3j, a first emission control driver 700, a second emission control driver 800, and a third emission control driver 900. Fig.13In the current embodiment, a first emission control driver 700, a second emission control driver 800, and a third emission control driver 900 are respectively shown, but the present invention is not limited thereto. For example, at least one of the first emission control driver 700, the second emission control driver 800, and the third emission control driver 900 may be provided in plural and may be located at different sides of the display area 600.

[0183] In some embodiments, the first emission control lines E11 to E1k are disposed in the first pixel region 602 so that they are connected to the first pixel PXL1, and the second emission control lines E21 to E2n may be disposed in the second pixel region 604 so that they are connected to the second pixel PXL2. In addition, the third emission control lines E31 to E3j may be located in the third pixel region 606 so that they are connected to the third pixel PXL3.

[0184] In some embodiments, the first emission control driver 700 may be connected to the first emission control lines E11 to E1k so that the emission control signals are sequentially supplied to the first emission control lines E11 to E1k. The second emission control driver 800 may be connected to the second emission control lines E21 to E2n so that the emission control signals are sequentially supplied to the second emission control lines E21 to E2n. The third emission control driver 900 may be connected to the third emission control lines E31 to E3j so that the emission control signals are sequentially supplied to the third emission control lines E31 to E3j. In some embodiments, the emission control signals output from the first emission control driver 700 to the third emission control driver 900 may be set to a gate-off voltage that can turn off the transistors included in the first pixel PXL1 to the third pixel PXL3.

[0185] In some embodiments, considering the area overlapping with the frame 31, the number of first scan lines S11 to S1k, first emission control lines E11 to E1k, third scan lines S31 to S3j and / or third emission control lines E31 to E3j may be differently set to two or more.

[0186] In addition, in this embodiment, the first pixel PXL1, the second pixel PXL2 and the third pixel PXL3 may include various forms of pixel circuits. For example, Fig.13 The first pixel PXL1, the second pixel PXL2, and the third pixel PXL3 shown in FIG. 4 may include various forms of pixel circuits, and the light emission time of the pixel circuits is controlled according to the emission control signal.

[0187] In the display device according to the aforementioned embodiment, the timing controller 500 may also generate a first emission start signal EFLM1, a second emission start signal EFLM2, a third emission start signal EFLM3, and clock signals (e.g., predetermined clock signals) CLK3 and CLK4 based on an externally supplied timing signal. The clock signals CLK3 and CLK4 generated by the timing controller 500 may be supplied to the first emission control driver 700, the second emission control driver 800, and the third emission control driver 900. In addition, the first emission start signal EFLM1 may be supplied to the first emission control driver 700, the second emission start signal EFLM2 may be supplied to the second emission control driver 800, and the third emission start signal EFLM3 may be supplied to the third emission control driver 900.

[0188] The first emission start signal EFLM1 controls the supply timing of the first emission control signal. The clock signals CLK3 and CLK4 supplied to the first emission control driver 700 are used to shift the first emission start signal EFLM1.

[0189] The second emission start signal EFLM2 controls the supply timing of the second emission control signal. The clock signals CLK3 and CLK4 supplied to the second emission control driver 800 are used to shift the second emission start signal EFLM2.

[0190] The third emission start signal EFLM3 controls the supply timing of the third emission control signal. The clock signals CLK3 and CLK4 supplied to the third emission control driver 900 are used to shift the third emission start signal EFLM3.

[0191] The display device according to the present embodiment can control the emission periods of the pixels PXL1, PXL2, and PXL3 according to the emission control signals output from the emission control drivers 700, 800, and 900. For example, the display device according to the present embodiment can control the light emission of the pixels PXL1, PXL2, and PXL3 in different ways according to the first mode and the second mode described above.

[0192] Fig.14 Shows Fig.13 An embodiment of one of the pixels shown in FIG. Fig.14 , for ease of description, pixels PXL1, PXL2, and PXL3 connected to an i-th data line Di and an i-th scan line Si (eg, any one of the first scan lines S11 to S1k, the second scan lines S21 to S2n, and the third scan lines S31 to S3j) will be shown.

[0193] Reference Fig.14, the pixels PXL1 , PXL2 , and PXL3 according to the present embodiment include an organic light emitting diode OLED and a pixel circuit 610 for controlling the amount of driving current supplied to the organic light emitting diode OLED.

[0194] The anode of the organic light emitting diode OLED is connected to the pixel circuit 610 , while the cathode of the organic light emitting diode OLED is connected to the second power source ELVSS. The organic light emitting diode OLED emits light with brightness corresponding to the amount of driving current supplied from the pixel circuit 610 .

[0195] The pixel circuit 610 controls the amount of current flowing from the first power source ELVDD to the second power source ELVSS via the organic light emitting diode OLED according to the data signal. To this end, the pixel circuit 610 includes a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a fifth transistor T5, a sixth transistor T6, a seventh transistor T7 and a storage capacitor Cst.

[0196] The seventh transistor T7 is connected between the initialization power supply Vint and the anode of the organic light emitting diode OLED. In addition, the gate electrode of the seventh transistor T7 is connected to the i-th scan line Si. When the scan signal is supplied to the i-th scan line Si, the seventh transistor T7 is turned on and supplies the voltage of the initialization power supply Vint to the anode of the organic light emitting diode OLED. In this case, the voltage of the initialization power supply Vint can be set to be equal to or less than the lowest voltage of the data signal.

[0197] The sixth transistor T6 is connected between the first transistor T1 and the organic light emitting diode OLED. In addition, the gate electrode of the sixth transistor T6 is connected to the emission control line Ei. The sixth transistor T6 is turned off when the emission control signal is supplied to the emission control line Ei, otherwise the sixth transistor T6 is turned on.

[0198] The fifth transistor T5 is connected between the first power source ELVDD and the first transistor T1. In addition, the gate electrode of the fifth transistor T5 is connected to the emission control line Ei. The fifth transistor T5 is turned off when the emission control signal is supplied to the emission control line Ei, otherwise the fifth transistor T5 is turned on.

[0199] A first electrode of the first transistor T1 (driving transistor) is connected to the first power source ELVDD through the fifth transistor T5, and a second electrode of the first transistor T1 is connected to the anode of the organic light emitting diode OLED through the sixth transistor T6. In addition, a gate electrode of the first transistor T1 is connected to a tenth node N10. The first transistor T1 controls the amount of driving current flowing from the first power source ELVDD to the second power source ELVSS via the organic light emitting diode OLED according to the voltage of the tenth node N10.

[0200] The third transistor T3 is connected between the second electrode of the first transistor T1 and the tenth node N10. In addition, the gate electrode of the third transistor T3 is connected to the i-th scan line Si. When the scan signal is supplied to the i-th scan line Si, the third transistor T3 is turned on and the second electrode of the first transistor T1 is electrically coupled to the tenth node N10. Therefore, when the third transistor T3 is turned on, the first transistor T1 is diode-connected.

[0201] The fourth transistor T4 is connected between the tenth node N10 and the initialization power supply Vint. In addition, the gate electrode of the fourth transistor T4 is connected to the i-1th scan line Si-1. When the scan signal is supplied to the i-1th scan line Si-1, the fourth transistor T4 is turned on and supplies the voltage of the initialization power supply Vint to the tenth node N10.

[0202] The second transistor T2 is connected between the i-th data line Di and the first electrode of the first transistor T1. In addition, the gate electrode of the second transistor T2 is connected to the i-th scan line Si. When the scan signal is supplied to the i-th scan line Si, the second transistor T2 is turned on and electrically combines the i-th data line Di and the first electrode of the first transistor T1.

[0203] The storage capacitor Cst is connected between the first power source ELVDD and the tenth node N10. The storage capacitor Cst stores a voltage corresponding to the voltage of the data signal and the threshold voltage of the first transistor T1.

[0204] Fig.15 Shows Fig.14 An embodiment of a pixel driving method is shown in FIG.

[0205] Reference Fig.15 , first, an emission control signal of a gate-off voltage is supplied to the emission control line Ei. When the emission control signal is supplied to the emission control line Ei, the fifth transistor T5 and the sixth transistor T6 are turned off. Therefore, the pixels PXL1, PXL2 and PXL3 are set to a non-emission state.

[0206] Subsequently, a scan signal is supplied to the i-1th scan line Si-1, so that the fourth transistor T4 is turned on. When the fourth transistor T4 is turned on, the voltage of the initialization power source Vint is supplied to the tenth node N10. Then, the tenth node N10 is initialized to the voltage of the initialization power source Vint.

[0207] After the tenth node N10 is initialized to the voltage of the initialization power source Vint, a scan signal is supplied to the i-th scan line Si. When the scan signal is supplied to the i-th scan line Si, the second transistor T2, the third transistor T3, and the seventh transistor T7 are turned on.

[0208] When the seventh transistor T7 is turned on, the voltage of the initialization power source Vint is supplied to the anode of the organic light emitting diode OLED. Then, the parasitic capacitor formed in the organic light emitting diode OLED is discharged, thereby improving the ability to express black grayscale.

[0209] For example, the parasitic capacitor of the organic light emitting diode OLED is charged with a certain voltage according to the current supplied from the previous frame. When the black grayscale is realized in the current frame, the organic light emitting diode OLED should maintain a non-emitting state. However, when the parasitic capacitor of the organic light emitting diode OLED maintains a charged state, the leakage current of the first transistor T1 causes the organic light emitting diode OLED to emit light weakly.

[0210] On the contrary, when the parasitic capacitor of the organic light emitting diode OLED is discharged, the leakage current of the first transistor T1 first charges the parasitic capacitor of the organic light emitting diode OLED. Therefore, the organic light emitting diode OLED maintains a non-emitting state.

[0211] When the third transistor T3 is turned on, the first transistor T1 is diode-connected.

[0212] When the second transistor T2 is turned on, the data signal from the i-th data line Di is supplied to the first electrode of the first transistor T1. In this case, since the tenth node N10 is initialized to the voltage of the initialization power supply Vint, the first transistor T1 is turned on. When the first transistor T1 is turned on, a voltage obtained by subtracting the threshold voltage of the first transistor T1 from the data signal is applied to the tenth node N10. A voltage corresponding to the voltage of the data signal applied to the tenth node N10 and a voltage corresponding to the threshold voltage of the first transistor T1 are stored in the storage capacitor Cst.

[0213] After storing a voltage corresponding to the voltage of the data signal and the threshold voltage of the first transistor T1 in the storage capacitor Cst, supply of the emission control signal to the emission control line Ei is stopped. Therefore, when supply of the emission control signal to the emission control line Ei is stopped, a gate-on voltage may be applied to the emission control line Ei.

[0214] When the emission control signal is stopped from being supplied to the emission control line Ei, the fifth transistor T5 and the sixth transistor T6 are turned on. Then, a current path is formed from the first power source ELVDD via the fifth transistor T5, the first transistor T1, the sixth transistor T6 and the organic light emitting diode OLED to the second power source ELVSS. In this case, the first transistor T1 controls the amount of driving current flowing from the first power source ELVDD via the organic light emitting diode OLED to the second power source ELVSS according to the voltage of the tenth node N10. Then, the organic light emitting diode OLED emits light having a brightness corresponding to the amount of driving current supplied from the first transistor T1.

[0215] The pixels PXL1, PXL2 and PXL3 repeatedly perform the above steps to generate light having a brightness corresponding to the data signal. In addition, in this embodiment, the circuit structure of the pixels PXL1, PXL2 and PXL3 is not limited to Fig.14 For example, the pixels PXL1, PXL2, and PXL3 may be implemented to have various forms.

[0216] The emission control signal supplied to the emission control line Ei is supplied to overlap with at least one scan signal, so that the pixels PXL1, PXL2 and PXL3 are set to a non-emission state for a period in which the data signal is charged to the pixels PXL1, PXL2 and PXL3. As an example, the emission control signal may overlap with the scan signal supplied to at least the current scan line (e.g., the i-th scan line Si), and may also overlap with the scan signal supplied to the previous scan line (e.g., the i-1-th scan line Si-1). The supply timing of the emission control signal may be set in various ways.

[0217] Fig.16 Shows Fig.13 An embodiment of an emission control driver is shown in FIG. Fig.16 , an embodiment in which the emission control driver is driven by two clock signals is disclosed, but the present invention is not limited thereto. That is, the number and / or type of clock signals input to the emission control driver may be changed.

[0218] Reference Fig.16According to the present embodiment, the first emission control driver 700 includes first emission control stages EST11 to EST1k, which are respectively connected to first emission control lines E11 to E1k, and the second emission control driver 800 includes second emission control stages EST21 to EST2n, which are respectively connected to second emission control lines E21 to E2n. In addition, the third emission control driver 900 includes third emission control stages EST31 to EST3j, which are respectively connected to third emission control lines E31 to E3j.

[0219] The first emission control stages EST11 to EST1k receive the first emission start signal EFLM1 and the clock signals CLK3 and CLK4 and supply a first emission control signal to each of the first emission control lines E11 to E1k according to the first emission start signal EFLM1.

[0220] The first first emission control stage EST11 supplies the first emission control signal to the first first emission control line E11 according to the first emission start signal EFLM1. The remaining first emission control stages EST12 to EST1k supply the first emission control signal to the first emission control line (any one of E12 to E1k) connected to the respective emission control stages EST12 to EST1k according to the output signal of the respective previous stage (e.g., the first emission control signal output from the previous stage).

[0221] In this case, the width of the first emission control signal is determined according to the width of the first emission start signal EFLM1. For example, the wider the width of the first emission start signal EFLM1 becomes, the wider the width of the first emission control signal becomes. Therefore, the width of the first emission control signal can be controlled by controlling the width of the first emission start signal EFLM1. The emission time of the first pixel PXL1 can be controlled by controlling the width of the first emission control signal.

[0222] In some embodiments, the width of the first emission start signal EFLM1 may be determined by the structure of the first pixel PXL1 and by the first scan signal supplied to the first scan lines S11 to S1k. For example, the first emission start signal EFLM1 may be set to have such a width that the first emission control signal supplied to the first first emission control line E11 overlaps the first scan signal supplied to the first first scan line S11.

[0223] The second emission control stages EST21 to EST2n receive the second emission start signal EFLM2 and the clock signals CLK3 and CLK4, and supply a second emission control signal to each of the second emission control lines E21 to E2n according to the second emission start signal EFLM2.

[0224] The first second emission control stage EST21 supplies the second emission control signal to the first second emission control line E21 according to the second emission start signal EFLM2. The remaining second emission control stages EST22 to EST2n provide second emission control signals to corresponding connected second emission control lines (any one of E22 to E2n) according to output signals of respective previous stages (e.g., second emission control signals output from the previous stage).

[0225] In this case, the width of the second emission control signal is determined according to the width of the second emission start signal EFLM2. For example, the wider the width of the second emission start signal EFLM2 becomes, the wider the width of the second emission control signal becomes. Therefore, the width of the second emission control signal can be controlled by controlling the width of the second emission start signal EFLM2. The emission time of the second pixel PXL2 can be controlled by controlling the width of the second emission control signal.

[0226] In some embodiments, the width of the second emission start signal EFLM2 may be determined by the structure of the second pixel PXL2 and by the second scan signal supplied to the second scan lines S21 to S2n. For example, the second emission start signal EFLM2 may be set to have such a width that the second emission control signal supplied to the first second emission control line E21 overlaps the second scan signal supplied to the first second scan line S21.

[0227] The third emission control stages EST31 to EST3j receive the third emission start signal EFLM3 and the clock signals CLK3 and CLK4, and supply a third emission control signal to each of the third emission control lines E31 to E3j according to the third emission start signal EFLM3.

[0228] The first third emission control stage EST31 supplies the third emission control signal to the first third emission control line E31 according to the third emission start signal EFLM3. The remaining third emission control stages EST32 to EST3j provide the third emission control signals to the respective connected third emission control lines (any one of E32 to E3j) according to the output signals of the respective previous stages (e.g., the third emission control signals outputted from the previous stages).

[0229] In this case, the width of the third emission control signal is determined according to the width of the third emission start signal EFLM3. For example, the wider the width of the third emission start signal EFLM3 becomes, the wider the width of the third emission control signal becomes. Therefore, the width of the third emission control signal can be controlled by controlling the width of the third emission start signal EFLM3. The emission time of the third pixel PXL3 can be controlled by controlling the width of the third emission control signal.

[0230] In some embodiments, the width of the third emission start signal EFLM3 may be determined by the structure of the third pixel PXL3 and by the third scan signal supplied to the third scan lines S31 to S3j. For example, the third emission start signal EFLM3 may be set to have such a width that the third emission control signal supplied to the first third emission control line E31 overlaps the third scan signal supplied to the first third scan line S31.

[0231] In the present embodiment, the configuration of the emission control stages EST11 to EST1k, EST21 to EST2n, and EST31 to EST3j is not specifically limited thereto. That is, the emission control stages EST11 to EST1k, EST21 to EST2n, and EST31 to EST3j control the width of the emission control signal supplied to the emission control lines E11 to E1k, E21 to E2n, and E31 to E3j according to the width of the emission start signals EFLM1, EFLM2, and EFLM3, and can be implemented by various forms of emission control circuits currently disclosed.

[0232] Fig.17 When driven in the first mode Fig.13 The display device shown in FIG. 1 is an embodiment of the driving timing of the emission control driver. In this case, the scanning line can be supplied with Figure 6 The scanning signal is shown in FIG.

[0233] Reference Fig.17, when the display device is driven in the first mode, the timing controller 500 sequentially supplies the first emission start signal EFLM1, the second emission start signal EFLM2, and the third emission start signal EFLM3 to the first emission control driver 700, the second emission control driver 800, and the third emission control driver 900, respectively. In this case, the first emission start signal EFLM1, the second emission start signal EFLM2, and the third emission start signal EFLM3 are set to have such a supply timing that the first emission control signal, the second emission control signal, and the third emission control signal are sequentially supplied to the first emission control lines E11 to E1k, the second emission control lines E21 to E2n, and the third emission control lines E31 to E3j, respectively. In some embodiments, the first emission start signal EFLM1, the second emission start signal EFLM2, and the third emission start signal EFLM3 may have the same width.

[0234] When the first emission start signal EFLM1 is supplied, the first emission control driver 700 sequentially supplies the first emission control signal to the first emission control lines E11 to E1k. In this case, the first emission control signal supplied to the i-th first emission control line E1i may be supplied to overlap with the first scan signal supplied to the i-th first scan line S1i.

[0235] When the second emission start signal EFLM2 is provided, the second emission control driver 800 sequentially supplies the second emission control signal to the second emission control lines E21 to E2n. In this case, the second emission control signal supplied to the i-th second emission control line E2i may be supplied to overlap with the second scan signal supplied to the i-th second scan line S2i.

[0236] When the third emission start signal EFLM3 is provided, the third emission control driver 900 sequentially supplies the third emission control signal to the third emission control lines E31 to E3j. In this case, the third emission control signal supplied to the i-th third emission control line E3i may be supplied to overlap with the third scan signal supplied to the i-th third scan line S3i.

[0237] When the display device is driven in the first mode, the first emission control driver 700, the second emission control driver 800, and the third emission control driver 900 repeat the above steps. That is, when the display device is driven in the first mode, the first emission control driver 700, the second emission control driver 800, and the third emission control driver 900 sequentially drive the first emission control lines E11 to E1k, the second emission control lines E21 to E2n, and the third emission control lines E31 to E3j in the order of the first pixel area 602, the second pixel area 604, and the third pixel area 606.

[0238] Fig.18 When driven in the second mode Fig.13 The display device shown in FIG. 1 is an embodiment of the driving timing of the emission control driver. In this case, the scanning line can be supplied with Fig. 9 The scanning signal is shown in FIG.

[0239] Reference Fig.18 When the display device is driven in the second mode, the timing controller 500 supplies the first emission start signal EFLM1 to the first emission control driver 700, the second emission start signal EFLM2 to the second emission control driver 800, and the third emission start signal EFLM3 to the third emission control driver 900 (for example, in a predetermined order).

[0240] In this case, the supply timings of the first emission start signal EFLM1, the second emission start signal EFLM2, and the third emission start signal EFLM3 are set so that the first emission control lines E11 to E1k and the third emission control lines E31 to E3j are driven for different periods, respectively, during which the second emission control lines E21 to E2n are sequentially driven. That is, in the present embodiment, the second emission control driver 800 sequentially drives the second emission control lines E21 to E2n according to the second mode, and the first emission control driver 700 and the third emission control driver 900 drive the first emission control lines E11 to E1k and the third emission control lines E31 to E3j, respectively, during different periods during which the second emission control lines E21 to E2n are driven.

[0241] For example, the timing controller 500 supplies the second emission start signal EFLM2 and the third emission start signal EFLM3 to the second emission control driver 800 and the third emission control driver 900 in parallel or simultaneously according to the second mode in each frame period, and at a specific time after the driving of the third emission control lines E31 to E3j is completed, the timing controller 500 may provide the first emission start signal EFLM1 to the first emission control driver 700. Therefore, the third emission control driver 900 may drive the third emission control lines E31 to E3j according to the second mode during the third period P3 (e.g., the initial period), and the second emission control driver 800 drives the second emission control lines E21 to E2n (e.g., some of the second emission control lines E21 to E2n) during the third period P3. In addition, the first emission control driver 700 may drive the first emission control lines E11 to E1k according to the second mode during a fourth period P4 (e.g., a subsequent period) after the third period P3, and the second emission control driver 800 drives the second emission control lines E21 to E2n (e.g., other ones of the second emission control lines E21 to E2n) during the fourth period P4.

[0242] The second emission control driver 800 may drive some of the second emission control lines (some of E21 to E2n) adjacent to the first pixel region 602 according to the second pattern in the third period P3. In addition, the second emission control driver 800 may drive some of the second emission control lines (other of E21 to E2n) adjacent to the third pixel region 606 according to the second pattern in the fourth period P4.

[0243] That is, when the display device is driven in the second mode, the second emission control signals supplied to some of the second emission control lines E21 to E2n may overlap with the third emission control signals supplied to the third emission control lines E31 to E3j. In addition, the second emission control signals supplied to other second emission control lines E21 to E2n may overlap with the first emission control signals supplied to the first emission control lines E11 to E1k. In this case, the first emission control signal may be supplied after the third emission control signal is supplied.

[0244] In some embodiments, the supply timing of the first emission start signal EFLM1 may depend on the number of the first emission control lines E11 to E1k and the second emission control lines E21 to E2n. For example, when k first emission control lines E11 to E1k (k is a natural number of 2 or more) are arranged in the first pixel region 602 (disposed at the upper end of the second pixel region 604), the supply timing of the first emission start signal EFLM1 may be set so that the k first emission control lines E11 to E1k are driven in parallel or simultaneously with the k second emission control lines E2 (n-k+1) to E2n disposed at the lower end region of the second pixel region 604. For example, when k first emission control lines E11 to E1k and n second emission control lines E21 to E2n (n is a natural number of k or greater) are respectively arranged in the first pixel area 602 and the second pixel area 604, the supply timing of the first emission start signal EFLM1 can be set so that the first emission control driver 700 and the second emission control driver 800 respectively provide emission control signals to the first first emission control line E11 and the n-k+1th second emission control line E2 (n-k+1) in parallel or simultaneously according to the second mode.

[0245] After receiving the second emission start signal EFLM2 and the third emission start signal EFLM3 from the timing controller 500 in parallel or simultaneously, the second emission control driver 800 and the third emission control driver 900 respectively output emission control signals to the first second emission control line E21 and the first third emission control line E31 according to the second emission start signal EFLM2 and the third emission start signal EFLM3. That is, the second emission control driver 800 and the third emission control driver 900 may provide emission control signals to the first second emission control line E21 and the first third emission control line E31 in parallel or simultaneously according to the second mode.

[0246] After receiving the first emission start signal EFLM1 from the timing controller 500, the first emission control driver 700 may output an emission control signal to the first first emission control line E11 according to the first emission start signal EFLM1. In addition, when the second emission control driver 800 outputs an emission control signal to the last second emission control line E2n, the first emission control driver 700 may output an emission control signal to the last first emission control line E1k. That is, the first emission control driver 700 and the second emission control driver 800 may supply emission control signals to the last first emission control line E1k and the last second emission control line E2n in parallel or simultaneously, respectively.

[0247] In some embodiments, when the display device is driven in the second mode, by controlling the width of the first emission start signal EFLM1 and / or the third emission start signal EFLM3, the first pixel region 602 and / or the third pixel region 606 can be reduced or prevented from actually emitting light. For example, in some embodiments, by increasing the width of the first emission start signal EFLM1 and / or the third emission start signal EFLM3, the emission time of the first pixel region 602 and / or the third pixel region 606 can be reduced to reduce the overall brightness of the first pixel region 602 and / or the third pixel region 606, or the emission of the first pixel region 602 and / or the third pixel region 606 can be selectively turned off. For example, the width of the first emission start signal EFLM1 and / or the third emission start signal EFLM3 can be increased so that the emission of the first pixel PXL1 and / or the third pixel PXL3 is reduced or prevented for at least some periods during which the display device is driven in the second mode.
