Description

Technical Field

[0001] Some aspects of the example embodiments generally relate to an organic light-emitting display device. Background Technology

[0002] To enhance the image quality of organic light-emitting diode (OLED) displays, their resolution can be increased. For example, OLED displays can have resolutions such as Full High Definition (FHD), Quadruple High Definition (QHD), and Ultra High Definition (UHD). Furthermore, OLED displays can operate at relatively high speeds (e.g., relatively high drive frequencies such as 90Hz or 120Hz). That is, because the number of scan lines included in the OLED display increases and the frame time for achieving a frame decreases, the horizontal time may decrease, the scan on-time (SOT) corresponding to the activation period of the scan signal may decrease, and therefore crosstalk may occur among the scan lines. As a result, when an OLED display capable of selectively performing display operations at different drive frequencies (e.g., capable of selectively operating at a drive frequency of 60Hz or 120Hz) has relatively high resolution and operates at relatively high speed, the image quality of the OLED display may actually degrade.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the background art, and therefore, the information discussed in this background section does not necessarily constitute prior art. Summary of the Invention

[0004] Some aspects of the example embodiments generally relate to an organic light-emitting display device. For example, some example embodiments of the invention relate to an organic light-emitting display device that can selectively perform display operations at different driving frequencies (e.g., selectively operate at a driving frequency of 60 Hz or 120 Hz).

[0005] Some example embodiments include an organic light-emitting display device that, when operating at a relatively high speed, can enhance image quality by ensuring sufficient horizontal time and sufficient scan conduction time, thereby preventing or reducing crosstalk in the scan lines.

[0006] According to some example embodiments, an organic light-emitting display device may include: a display panel comprising a plurality of pixels; a data driver electrically connected to a data line of the display panel and configured to divide a frame into odd-numbered subframes and even-numbered subframes, divide frame data used to implement a frame into odd-numbered subframe data and even-numbered subframe data, provide odd-numbered subframe data to the data line in odd-numbered subframes and provide even-numbered subframe data to the data line in even-numbered subframes; and an odd-numbered scan driver electrically connected to an odd-numbered scan line among the scan lines of the display panel and configured to provide odd-numbered subframe data to the data line in odd-numbered subframes. Odd-numbered scan signals are provided to odd-numbered scan lines; an even-numbered scan driver is electrically connected to an even-numbered scan line among the scan lines of the display panel and is configured to provide even-numbered scan signals to even-numbered scan lines in even-numbered subframes; a transmit driver is electrically connected to a transmit line of the display panel and is configured to provide transmit signals to transmit line groups formed by grouping transmit lines according to two adjacent transmit lines in both odd-numbered and even-numbered subframes; and a timing controller is configured to control the data driver, the odd-numbered scan driver, the even-numbered scan driver, and the transmit driver.

[0007] According to some example embodiments, the non-light-emitting operation of a target pixel electrically connected to a target emission line group to which an emission signal is applied can be performed simultaneously (or concurrently) during the deactivation period of the emission signal, and the light-emitting operation of the target pixel can be performed simultaneously (or concurrently) during the activation period of the emission signal.

[0008] According to some example embodiments, the timing controller can adjust the brightness of the display panel by adjusting the ratio between the activation period and the deactivation period of the transmitted signal.

[0009] According to some example embodiments, in odd-numbered subframes, during the deactivation period of the transmitted signal, a data write operation of a first target pixel electrically connected to an odd-numbered scan line can be performed, and a data write operation of a second target pixel electrically connected to an even-numbered scan line can be omitted.

[0010] According to some example embodiments, in odd-numbered subframes, during the active period of the transmitted signal, a first target pixel may emit light based on the current odd-numbered subframe data, and a second target pixel may emit light based on the previous even-numbered subframe data.

[0011] According to some example embodiments, in even-numbered subframes, during the deactivation period of the transmitted signal, the data write operation of a first target pixel electrically connected to an odd-numbered scan line may not be performed, and the data write operation of a second target pixel electrically connected to an even-numbered scan line may be performed.

[0012] According to some example embodiments, in an even-numbered subframe, during the active period of the transmitted signal, a first target pixel may emit light based on the data of the previous odd-numbered subframe, and a second target pixel may emit light based on the data of the current even-numbered subframe.

[0013] According to some example embodiments, an odd-numbered scan driver may include a first scan level to a 2k-1 scan level that sequentially generates odd-numbered scan signals, where k is an integer greater than or equal to 1. Furthermore, when the timing controller applies an odd-numbered scan start signal to the first scan level in an odd-numbered subframe, the odd-numbered scan driver may sequentially provide the odd-numbered scan signals to the odd-numbered scan lines.

[0014] According to some example embodiments, in even-numbered subframes, the timing controller may not apply the odd-numbered scan start signal to the first scan level, and the clock signals applied to the first scan level to the (2k-1)th scan level may have a low voltage level.

[0015] According to some example embodiments, an even-numbered scan driver may include a second scan level to a 2k scan level that sequentially generates even-numbered scan signals. Furthermore, when the timing controller applies an even-numbered scan start signal to the second scan level in an even-numbered subframe, the even-numbered scan driver may sequentially provide even-numbered scan signals to even-numbered scan lines.

[0016] According to some example embodiments, in odd-numbered subframes, the timing controller may not apply the even-numbered scan start signal to the second scan level, and the clock signal applied to the second scan level to the 2kth scan level may have a low voltage level.

[0017] According to some example embodiments, the pulse width of the odd-numbered scan start signal can be equal to the pulse width of the odd-numbered scan signal, and the pulse width of the even-numbered scan start signal can be equal to the pulse width of the even-numbered scan signal.

[0018] According to some example embodiments, the pulse width of the odd-numbered scan start signal can be greater than the pulse width of the odd-numbered scan signal, and the pulse width of the even-numbered scan start signal can be greater than the pulse width of the even-numbered scan signal.

[0019] According to some example embodiments, each of the transmit signal groups may include odd-numbered transmit lines and even-numbered transmit lines, and the odd-numbered transmit lines may not be electrically connected to the even-numbered transmit lines.

[0020] According to some example embodiments, a transmit driver may include: an odd-numbered transmit driver that sequentially provides transmit signals to odd-numbered transmit lines, and an even-numbered transmit driver that sequentially provides transmit signals to even-numbered transmit lines, wherein the odd-numbered transmit driver and the even-numbered transmit driver may provide transmit signals simultaneously (or concurrently) to each transmit line group.

[0021] According to some example embodiments, the odd-numbered transmit driver can be electrically connected to the odd-numbered transmit line and can include a first transmit stage to a (2k-1)th transmit stage that sequentially generates transmit signals, where k is an integer greater than or equal to 1. Furthermore, when the timing controller applies a transmit start signal to the first transmit stage in odd-numbered and even-numbered subframes, the odd-numbered transmit driver can sequentially provide transmit signals to the odd-numbered transmit line.

[0022] According to some example embodiments, even-numbered transmit drivers can be electrically connected to even-numbered transmit lines and can include second to 2k transmit stages that sequentially generate transmit signals. Furthermore, when the timing controller applies a transmit start signal to the second transmit stage in odd-numbered and even-numbered subframes, the even-numbered transmit drivers can sequentially provide transmit signals to the even-numbered transmit lines.

[0023] According to some example embodiments, the timing controller can simultaneously (or concurrently) apply the transmit start signal to the first and second transmit stages in odd-numbered and even-numbered subframes.

[0024] According to some example embodiments, each of the transmitter groups may include odd-numbered transmitters and even-numbered transmitters, and the odd-numbered transmitters may be electrically connected to the even-numbered transmitters.

[0025] According to some example embodiments, the transmit driver may be electrically connected to a group of transmit lines and includes a first transmit stage to a k-th transmit stage that sequentially generates transmit signals. Furthermore, the transmit driver may sequentially provide transmit signals to the group of transmit lines when the timing controller applies a transmit start signal to the first transmit stage in odd-numbered and even-numbered subframes.

[0026] Therefore, an organic light-emitting display device according to some example embodiments may include: a display panel including a plurality of pixels; a data driver that provides odd-numbered subframe data to data lines in odd-numbered subframes and even-numbered subframe data to data lines in even-numbered subframes; an odd-numbered scan driver that provides odd-numbered scan signals to odd-numbered scan lines in odd-numbered subframes; an even-numbered scan driver that provides even-numbered scan signals to even-numbered scan lines in even-numbered subframes; an emission driver that provides emission signals to emission line groups formed by grouping emission lines according to two adjacent emission lines in both odd-numbered and even-numbered subframes; and a timing controller that controls the data driver, the odd-numbered scan driver, the even-numbered scan driver, and the emission driver. Therefore, when an organic light-emitting display device operates at a relatively high speed, an organic light-emitting display device that can selectively perform display operations at different drive frequencies can ensure sufficient horizontal time and sufficient scan conduction time, so that the organic light-emitting display device can prevent crosstalk in the scan lines to enhance image quality.

[0039] In the following sections, some exemplary embodiments of the inventive concept will be explained in more detail with reference to the accompanying drawings.

[0040] Figure 1 This is a block diagram illustrating an organic light-emitting display device according to some example embodiments. Figure 2 It is shown in the diagram. Figure 1 A schematic diagram of an example of an organic light-emitting display device operating at a first driving frequency, and Figure 3 and Figure 4 It is shown in the diagram.

[0041] Reference Figures 1 to 4 The organic light-emitting display device 100 may include a display panel 110, a data driver 120, odd-numbered scan drivers 130, even-numbered scan drivers 140, an emission driver 150, and a timing controller 160. Here, the organic light-emitting display device 100 can selectively perform display operations at different driving frequencies (for example, it can selectively operate at a driving frequency of 60 Hz or 120 Hz).

[0042] Display panel 110 may include a plurality of pixels 111. Pixels 111 may be arranged in various forms (e.g., matrix form, etc.) in display panel 110. Each of pixels 111 may include at least one of red display pixels, green display pixels, and blue display pixels.

[0043] The data driver 120 can be electrically connected to the data line of the display panel 110. Here, when the organic light-emitting display device 100 operates at a first driving frequency (i.e., a relatively low driving frequency), the data driver 120 can provide frame data OSD and ESD for implementing a frame 1F to the data line within a frame 1F. For example, as... Figure 2 As illustrated, when the organic light-emitting display device 100 operates at a first driving frequency (e.g., a driving frequency of 60 Hz), the data driver 120 can sequentially provide frame data DATA (i.e., indicated by S1, S2, S3, S4, etc.) to the data lines in response to scan signals SS(1), SS(2), SS(3), SS(4), etc. (e.g., SS(1), SS(2), SS(3), SS(4), ..., SS(2k-1), SS(2k)) that are sequentially applied to the scan lines during a frame 1F (i.e., during the frame time (e.g., 1 / 60 seconds)).

[0044] On the other hand, when the organic light-emitting display device 100 operates at a second driving frequency (i.e., a relatively high frequency), the data driver 120 can divide a frame 1F into odd-numbered subframes SF1 and even-numbered subframes SF2, divide the frame data OSD and ESD used to implement a frame 1F into odd-numbered subframe data OSD and even-numbered subframe data ESD, provide odd-numbered subframe data OSD to the data line in odd-numbered subframes SF1, and provide even-numbered subframe data ESD to the data line in even-numbered subframes SF2.

[0045] For example, such as Figure 3 As illustrated, when the organic light-emitting display device 100 operates at a second driving frequency (e.g., a driving frequency of 120 Hz), the data driver 120 can sequentially provide odd-numbered subframe data OSD (i.e., indicated by S1, S3, S5, etc.) to the data lines in response to odd-numbered scan signals SS(1), SS(3), SS(5), etc., which are sequentially applied to the odd-numbered scan lines during the odd-numbered subframe SF1 (i.e., during the subframe time (e.g., 1 / 120 seconds)). Furthermore, as... Figure 4As illustrated, when the organic light-emitting display device 100 operates at a second driving frequency (e.g., a driving frequency of 120 Hz), the data driver 120 can sequentially provide even-numbered subframe data ESD (i.e., indicated by S2, S4, S6, etc.) to the data lines in response to even-numbered scan signals SS(2), SS(4), SS(6), etc., which are sequentially applied to even-numbered scan lines during even-numbered subframes SF2 (i.e., during the subframe time (e.g., 1 / 120 seconds)).

[0046] Odd-numbered scan drivers 130 can be electrically connected to odd-numbered scan lines in the scan lines of the display panel 110. Even-numbered scan drivers 140 can be electrically connected to even-numbered scan lines in the scan lines of the display panel 110. Here, when the organic light-emitting display device 100 operates at a first driving frequency (i.e., a relatively low driving frequency), the scan drivers (i.e., odd-numbered scan drivers 130 and even-numbered scan drivers 140) can sequentially provide scan signals SS(1), SS(2), SS(3), SS(4), etc. to the scan lines in one frame 1F. For example, as Figure 2 As illustrated, when the organic light-emitting display device 100 operates at a first driving frequency (e.g., a driving frequency of 60 Hz), the odd-numbered scan driver 130 and the even-numbered scan driver 140 can operate as a single scan driver to sequentially provide scan signals SS(1), SS(2), SS(3), SS(4), etc. to the scan lines within a frame 1F (i.e., during the frame time (e.g., 1 / 60 seconds)).

[0047] On the other hand, when the organic light-emitting display device 100 operates at a second driving frequency (i.e., a relatively high driving frequency), the odd-numbered scan driver 130 can sequentially provide odd-numbered scan signals SS(1), SS(3), SS(5), etc. to the odd-numbered scan lines in the odd-numbered subframe SF1, and the even-numbered scan driver 140 can sequentially provide even-numbered scan signals SS(2), SS(4), SS(6), etc. to the even-numbered scan lines in the even-numbered subframe SF2. For example, as Figure 3 As illustrated, when the organic light-emitting display device 100 operates at a second driving frequency (e.g., a driving frequency of 120 Hz), the odd-numbered scan driver 130 can sequentially provide odd-numbered scan signals SS(1), SS(3), SS(5), etc., to the odd-numbered scan lines during the odd-numbered subframe SF1 (i.e., during the subframe time (e.g., 1 / 120 second)). Furthermore, as... Figure 4As illustrated, when the organic light-emitting display device 100 operates at a second driving frequency (e.g., a driving frequency of 120 Hz), the even-numbered scan driver 140 can sequentially provide even-numbered scan signals SS(2), SS(4), SS(6), etc. to the even-numbered scan lines during the even-numbered subframe SF2 (i.e., during the subframe time (e.g., 1 / 120 seconds)).

[0048] Therefore, the odd-numbered scan driver 130 may include a first scan level to a 2k-1 scan level that sequentially generates odd-numbered scan signals SS(1), SS(3), SS(5), etc., where k is an integer greater than or equal to 1, and when the timing controller 160 applies an odd-numbered scan start signal SOSP to the first scan level in an odd-numbered subframe SF1, the odd-numbered scan signals SS(1), SS(3), SS(5), etc., may be sequentially provided to the odd-numbered scan lines. According to some example embodiments, such as Figure 3 As shown in the figure, the pulse width of the odd-numbered scan start signal SOSP can be equal to the pulse width of the odd-numbered scan signals SS(1), SS(3), SS(5), etc.

[0049] Furthermore, the even-numbered scan driver 140 may include a second scan level to a 2k scan level that sequentially generates even-numbered scan signals SS(2), SS(4), SS(6), etc., and when the timing controller 160 applies an even-numbered scan start signal SESP to the second scan level in an even-numbered subframe SF2, the even-numbered scan signals SS(2), SS(4), SS(6), etc., may be sequentially provided to the even-numbered scan lines. According to some example embodiments, such as Figure 4 As illustrated in the diagram, the pulse width of the even-numbered scan start signal SESP can be equal to the pulse width of the even-numbered scan signals SS(2), SS(4), SS(6), etc. (Refer to...) Figure 8 and Figure 9 Describe these operations in detail.

[0050] The transmitter driver 150 can be electrically connected to the transmitter lines of the display panel 110. Here, the transmitter lines can be grouped according to two adjacent transmitter lines to form a transmitter line group. For example, as... Figures 2 to 4As illustrated, a first emission line (i.e., an odd-numbered emission line) connected to pixels connected to a first scan line (i.e., an odd-numbered scan line) and a second emission line (i.e., an even-numbered emission line) connected to pixels connected to a second scan line (i.e., an even-numbered scan line) can form a first emission line group. A third emission line (i.e., an odd-numbered emission line) connected to pixels connected to a third scan line (i.e., an odd-numbered scan line) and a fourth emission line (i.e., an even-numbered emission line) connected to pixels connected to a fourth scan line (i.e., an even-numbered scan line) can form a second emission line group. The fifth emission line (i.e., the odd-numbered emission line) connected to the pixel of the fifth scan line (i.e., the odd-numbered scan line) and the sixth emission line (i.e., the even-numbered emission line) connected to the pixel of the sixth scan line (i.e., the even-numbered scan line) can form a third emission line group, and the 2k-1 emission line (i.e., the odd-numbered emission line) connected to the pixel of the 2k-1 scan line (i.e., the odd-numbered scan line) and the 2k emission line (i.e., the even-numbered emission line) connected to the pixel of the 2k scan line (i.e., the even-numbered scan line) can form a k emission line group. Here, when the organic light-emitting display device 100 operates at a first driving frequency (i.e., a relatively low driving frequency), the emission driver 150 can provide emission signals EM(1), EM(2), EM(3), etc. to the emission line group formed by grouping emission lines according to two adjacent emission lines in one frame 1F.

[0051] For example, such as Figure 2 As illustrated, when the organic light-emitting display device 100 operates at a first driving frequency (e.g., a driving frequency of 60 Hz), the emission driver 150 can sequentially provide emission signals EM(1), EM(2), EM(3), etc. to the emission line group in a frame 1F (i.e., during the frame time (e.g., 1 / 60 second)). On the other hand, when the organic light-emitting display device 100 operates at a second driving frequency (i.e., a relatively high driving frequency), the emission driver 150 can provide emission signals EM(1), EM(2), EM(3), etc. to the emission line group formed by grouping emission lines according to two adjacent emission lines in odd-numbered subframes SF1 and even-numbered subframes SF2.

[0052] For example, such as Figure 3 As illustrated, when the organic light-emitting display device 100 operates at a second driving frequency (i.e., a driving frequency of 120 Hz), the emission driver 150 can sequentially provide emission signals EM(1), EM(2), EM(3), etc., to the emission line group during odd-numbered subframes SF1 (i.e., during the subframe time (e.g., 1 / 120 second)). Furthermore, as... Figure 4 As illustrated, when the organic light-emitting display device 100 operates at a second driving frequency (e.g., a driving frequency of 120 Hz), the emission driver 150 can sequentially provide emission signals EM(1), EM(2), EM(3), etc. to the emission line group during even-numbered subframes SF2 (i.e., during the subframe time (e.g., 1 / 120 seconds)).

[0053] According to some example embodiments, each of the transmitter line groups may include odd-numbered transmitter lines and even-numbered transmitter lines, and the odd-numbered transmitter lines and even-numbered transmitter lines may not be electrically connected to each other. In this case, the transmitter driver 150 may include an odd-numbered transmitter driver that sequentially provides the transmitter signals EM(1), EM(2), EM(3), etc. to the odd-numbered transmitter lines, and an even-numbered transmitter driver that sequentially provides the transmitter signals EM(1), EM(2), EM(3), etc. to the even-numbered transmitter lines, and the odd-numbered transmitter driver and the even-numbered transmitter driver may simultaneously (or concurrently) provide the transmitter signals EM(1), EM(2), EM(3), etc. to each of the transmitter line groups.

[0054] Here, the odd-numbered transmit drivers can be electrically connected to the odd-numbered transmit lines and can include a first transmit stage to a 2k-1 transmit stage that sequentially generates transmit signals EM(1), EM(2), EM(3), etc. Furthermore, when the timing controller 160 applies the transmit start signal ESP to the first transmit stage in the odd-numbered subframe SF1 and the even-numbered subframe SF2, the odd-numbered transmit drivers can sequentially provide transmit signals EM(1), EM(2), EM(3), etc., to the odd-numbered transmit lines. The even-numbered transmit drivers can be electrically connected to the even-numbered transmit lines and can include a second transmit stage to a 2k-1 transmit stage that sequentially generates transmit signals EM(1), EM(2), EM(3), etc.

[0055] Furthermore, when the timing controller 160 applies the transmit start signal ESP to the second transmit stage in odd-numbered subframe SF1 and even-numbered subframe SF2, the even-numbered transmit driver can sequentially provide transmit signals EM(1), EM(2), EM(3), etc., to the even-numbered transmit lines. The timing controller 160 can simultaneously (or concurrently) apply the transmit start signal ESP to the first and second transmit stages in odd-numbered subframe SF1 and even-numbered subframe SF2. According to some example embodiments, each transmit line group in the transmit line group may include odd-numbered transmit lines and even-numbered transmit lines, and the odd-numbered transmit lines and even-numbered transmit lines may be electrically connected to each other. In this case, the transmit driver 150 may be electrically connected to the transmit line group and may include the first to the kth transmit stages that sequentially generate transmit signals EM(1), EM(2), EM(3), etc. When the timing controller 160 applies the transmit start signal ESP to the first transmit stage in odd-numbered subframe SF1 and even-numbered subframe SF2, the transmit driver 150 can sequentially provide transmit signals EM(1), EM(2), EM(3), etc., to the transmit line group. (Refer to...) Figure 6 and Figure 7 Describe these operations in detail.

[0056] The timing controller 160 can control the data driver 120, the odd-numbered scan driver 130, the even-numbered scan driver 140, and the transmit driver 150. To this end, the timing controller 160 can generate first control signals to fourth control signals CTL1, ..., CTL4 to provide the first control signals to the fourth control signals CTL1, ..., CTL4 to the data driver 120, the odd-numbered scan driver 130, the even-numbered scan driver 140, and the transmit driver 150, respectively. The timing controller 160 can provide the odd-numbered scan start signal SOSP to the odd-numbered scan driver 130, so that the odd-numbered scan driver 130 can sequentially provide the odd-numbered scan signals SS(1), SS(3), SS(5), etc., to the odd-numbered scan lines.

[0057] For example, such as Figure 2 As illustrated, the timing controller 160 can provide the odd-numbered scan start signal SOSP to the first scan stage of the odd-numbered scan driver 130 in a frame 1F, so that the odd-numbered scan driver 130 can sequentially provide the odd-numbered scan signals SS(1), SS(3), SS(5), etc., to the odd-numbered scan lines. Furthermore, as shown... Figure 3As illustrated, the timing controller 160 can control the odd-numbered scan driver 130 to sequentially provide odd-numbered scan signals SS(1), SS(3), SS(5), etc., to the odd-numbered scan lines by applying the odd-numbered scan start signal SOSP to the first scan stage of the odd-numbered scan driver 130 in the odd-numbered subframe SF1. On the other hand, as shown in the figure, Figure 4 As shown in the figure, the timing controller 160 can control the odd-numbered scan driver 130 not to provide the odd-numbered scan signals SS(1), SS(3), SS(5), etc. to the odd-numbered scan lines by not applying the odd-numbered scan start signal SOSP to the first scan stage of the odd-numbered scan driver 130 in the even-numbered subframe SF2.

[0058] The timing controller 160 can provide the even-numbered scan start signal SESP to the even-numbered scan driver 140, so that the even-numbered scan driver 140 can sequentially provide the even-numbered scan signals SS(2), SS(4), SS(6), etc., to the even-numbered scan lines. For example, Figure 2 As illustrated, the timing controller 160 can provide the even-numbered scan start signal SESP to the second scan stage of the even-numbered scan driver 140 in a frame 1F, so that the even-numbered scan driver 140 can sequentially provide the even-numbered scan signals SS(2), SS(4), SS(6), etc., to the even-numbered scan lines. Furthermore, as shown in the figure... Figure 4 As shown in the figure, the timing controller 160 can control the even-numbered scan driver 140 to sequentially provide even-numbered scan signals SS(2), SS(4), SS(6), etc. to the even-numbered scan lines by applying the even-numbered scan start signal SESP to the second scan stage of the even-numbered scan driver 140 in the even-numbered subframe SF2.

[0059] On the other hand, such as Figure 3 As illustrated, the timing controller 160 can control the even-numbered scan driver 140 not to provide even-numbered scan signals SS(2), SS(4), SS(6), etc. to even-numbered scan lines in odd-numbered subframes SF1 by not applying the even-numbered scan start signal SESP to the second scan stage of the even-numbered scan driver 140. The timing controller 160 can provide the transmit start signal ESP to the transmit driver 150, so that the transmit driver 150 can sequentially provide transmit signals EM(1), EM(2), EM(3), etc. to the transmit line group. For example, as Figures 2 to 4As illustrated, timing controller 160 can control transmitter driver 150 to sequentially provide transmit signals EM(1), EM(2), EM(3), etc. to the transmit line group by applying a transmit start signal ESP to the first transmit stage of transmitter driver 150 in odd-numbered subframe SF1 and even-numbered subframe SF2, as well as in a frame 1F. According to some example embodiments, timing controller 160 can perform specific processing (e.g., degradation compensation, etc.) on image data input from external components.

[0060] like Figures 2 to 4 As illustrated in the figure, non-light-emitting operations (e.g., initialization operations, threshold voltage compensation operations, data writing operations, etc.) of the target pixel electrically connected to the target emission line group to which emission signals EM(1), EM(2), EM(3), etc., are applied can occur during the deactivation period of the emission signals EM(1), EM(2), EM(3), etc. (i.e., Figures 2 to 4 The emission operation of the target pixel, which is electrically connected to the target emission line group to which emission signals EM(1), EM(2), EM(3), etc. are applied, can be performed simultaneously (or concurrently) during the period when the voltage level is high, and can be performed during the activation period of the emission signals EM(1), EM(2), EM(3), etc. (i.e., Figures 2 to 4 They are executed simultaneously (or concurrently) during periods when there is a low voltage level.

[0061] For example, such as Figures 2 to 4 As illustrated in the figure, the activation periods of even-numbered scan signals SS(2), SS(4), SS(6), etc. and / or odd-numbered scan signals SS(1), SS(3), SS(5), etc., applied to the target pixel (i.e., Figures 2 to 4 The period with a low voltage level exists during the deactivation period of the emission signals EM(1), EM(2), EM(3), etc., applied to the target pixel, so the data writing operation of the target pixel can be performed. On the other hand, such as Figures 2 to 4 As illustrated in the figure, the deactivation period (i.e.,) of the even-numbered scan signals SS(2), SS(4), SS(6), etc. and / or the odd-numbered scan signals SS(1), SS(3), SS(5), etc. applied to the target pixel is due to the activation period of the target pixel. Figures 2 to 4 The high voltage level period exists during the activation period of the emission signals EM(1), EM(2), EM(3), etc., applied to the target pixel, so the emission operation of the target pixel can be performed. For example, as Figure 3As illustrated in the figure, in the odd-numbered subframe SF1, during the deactivation period of the transmitted signals EM(1), EM(2), EM(3), etc., the first target pixel electrically connected to the odd-numbered scan line can perform a data writing operation, and the odd-numbered scan line is applied with the odd-numbered scan signals SS(1), SS(3), SS(5), etc. with activation level, and the second target pixel electrically connected to the even-numbered scan line can not perform a data writing operation, and the even-numbered scan line is applied with the even-numbered scan signals SS(2), SS(4), SS(6), etc. with deactivation level.

[0062] As a result, in the odd-numbered subframe SF1, during the activation period of the transmitted signals EM(1), EM(2), EM(3), etc., the first target pixel can emit light based on the current odd-numbered subframe data (i.e., the odd-numbered subframe data OSD written by the data write operation in the current odd-numbered subframe), and the second target pixel can emit light based on the previous even-numbered subframe data (i.e., the even-numbered subframe data ESD written by the data write operation in the previous even-numbered subframe). On the other hand, as Figure 4 As illustrated in the figure, in the even-numbered subframe SF2, during the deactivation period of the transmitted signals EM(1), EM(2), EM(3), etc., the first target pixel electrically connected to the odd-numbered scan line can not perform a data writing operation, the odd-numbered scan line is applied with the odd-numbered scan signals SS(1), SS(3), SS(5), etc. with deactivation level, and the second target pixel electrically connected to the even-numbered scan line can perform a data writing operation, the even-numbered scan line is applied with the even-numbered scan signals SS(2), SS(4), SS(6), etc. with activation level.

[0063] As a result, in the even-numbered subframe SF2, during the activation period of the transmitted signals EM(1), EM(2), EM(3), etc., the first target pixel can emit light based on the data of the previous odd-numbered subframe (i.e., the odd-numbered subframe data OSD written by the data write operation in the previous odd-numbered subframe), and the second target pixel can emit light based on the data of the current even-numbered subframe (i.e., the even-numbered subframe data ESD written by the data write operation in the current even-numbered subframe).

[0064] As described above, the organic light-emitting display device 100 may include: a display panel 110 including pixels 111, a data driver 120 electrically connected to data lines of the display panel 110, an odd-numbered scan driver 130 electrically connected to odd-numbered scan lines of the scan lines of the display panel 110, an even-numbered scan driver 140 electrically connected to even-numbered scan lines of the scan lines of the display panel 110, an emission driver 150 electrically connected to emission lines of the display panel 110, and a timing controller 160 controlling the data driver 120, the odd-numbered scan driver 130, the even-numbered scan driver 140, and the emission driver 150. The data driver 120 divides a frame 1F into odd-numbered subframes SF1 and even-numbered subframes SF2, and divides the frame data OSD and ESD used to implement a frame 1F into odd-numbered subframes. According to OSD and even-numbered subframe data ESD, in odd-numbered subframe SF1, the odd-numbered subframe data OSD is provided to the data line, and in even-numbered subframe SF2, the even-numbered subframe data ESD is provided to the data line. The odd-numbered scan driver 130 provides the odd-numbered scan signals SS(1), SS(3), SS(5), etc. to the odd-numbered scan line in the odd-numbered subframe SF1. The even-numbered scan driver 140 provides the even-numbered scan signals SS(2), SS(4), SS(6), etc. to the even-numbered scan line in the even-numbered subframe SF2. The transmit driver 150 provides the transmit signals EM(1), EM(2), EM(3), etc. to the transmit line group formed by grouping the transmit lines according to two adjacent transmit lines in both odd-numbered subframe SF1 and even-numbered subframe SF2.

[0065] Therefore, when the organic light-emitting display device 100 operates at a relatively high speed, the organic light-emitting display device 100, which can selectively perform display operations at different driving frequencies (e.g., selectively operate at a driving frequency of 60 Hz or 120 Hz), can ensure sufficient horizontal time and sufficient scan conduction time (i.e., Figure 3 and Figure 4 The activation period 2H of the scan signal SS shown is compared to Figure 2 The activation period of the scan signal SS shown is 1 hour long. Figure 3 and Figure 4 The scan conduction time of the scan signal SS shown is compared to Figure 2The scanning signal SS shown has a long scan conduction time, thus achieving the effect of increasing the horizontal time. As a result, the organic light-emitting display device 100 can prevent or reduce crosstalk in the scan lines to enhance image quality. For ease of description, although the organic light-emitting display device 100 is described above as operating selectively at a driving frequency of 60 Hz or 120 Hz, the driving frequency of the organic light-emitting display device 100 is not limited to this.

[0066] Figure 5 The illustration is included in Figure 1 A schematic diagram of the emission signal generated by the emission driver in an organic light-emitting display device.

[0067] Reference Figure 5 When the organic light-emitting display device 100 is driven (i.e., operated) at a relatively high speed, the emission signal EM can include a deactivation period DAP and an activation period ACP within a subframe SF (i.e., in each of the odd-numbered subframe SF1 and the even-numbered subframe SF2). As described above, pixel 111 can perform non-light-emitting operations (e.g., including initialization operations, threshold voltage compensation operations, data writing operations, etc.) during the deactivation period DAP of the emission signal EM, and can perform light-emitting operations during the activation period ACP of the emission signal EM.

[0068] In other words, when the deactivation period (DAP) of the emitted signal EM decreases and the activation period (ACP) of the emitted signal EM increases, the brightness of the display panel 110 can increase. On the other hand, when the deactivation period (DAP) of the emitted signal EM increases and the activation period (ACP) of the emitted signal EM decreases, the brightness of the display panel 110 can decrease. Therefore, the organic light-emitting display device 100 (e.g., timing controller 160) can adjust the brightness of the display panel 110 by adjusting the ratio between the activation period (ACP) and the deactivation period (DAP) of the emitted signal EM.

[0069] Unlike interlaced scanning OLEDs that divide a frame 1F into odd-numbered subframes SF1 and even-numbered subframes SF2, where only pixels 111 connected to odd-numbered scan lines are controlled to emit light in odd-numbered subframes SF1 and even-numbered subframes SF2, OLED OLED 100 can divide a frame 1F into odd-numbered subframes SF1 and even-numbered subframes SF2. It can control both pixels 111 connected to even-numbered scan lines and pixels 111 connected to odd-numbered scan lines to emit light in odd-numbered subframes SF1 and even-numbered scan lines to emit light in even-numbered subframes SF2. Therefore, OLED OLED 100 can solve (or overcome) the problems of OLEDs using interlaced scanning technology (e.g., brightness degradation, pattern retention, etc.).

[0070] Figure 6 The illustration includes Figure 1 A block diagram of an example emission driver in an organic light-emitting display device.

[0071] Reference Figure 6 The transmitter driver 150-1 can be electrically connected to the transmitter lines EL(1), EL(2), EL(3), EL(4), EL(5), EL(6), etc. of the display panel 110. Here, the transmitter lines EL(1), EL(2), EL(3), EL(4), EL(5), EL(6), etc. can be grouped according to two adjacent transmitter lines to form (or constitute) transmitter line groups. For example, the first transmitter line EL(1) and the second transmitter line EL(2) can form a first transmitter line group, the third transmitter line EL(3) and the fourth transmitter line EL(4) can form a second transmitter line group, the fifth transmitter line EL(5) and the sixth transmitter line EL(6) can form a third transmitter line group, and the 2k-1 transmitter line EL(2k-1) and the 2k transmitter line EL(2k) can form a k transmitter line group.

[0072] Transmit driver 150-1 can sequentially provide the first transmit signal to the k-th transmit signal EM(1), ..., EM(k) to the first transmit line group to the k-th transmit line group. Here, as... Figure 6As shown in the figure, each of the first to the kth transmitter groups may include transmitters with odd numbers such as EL(1), EL(3), EL(5) and transmitters with even numbers such as EL(2), EL(4), EL(6), etc., and transmitters with odd numbers such as EL(1), EL(3), EL(5) may not be electrically connected to transmitters with even numbers such as EL(2), EL(4), EL(6). In this case, the transmitter driver 150-1 may include: an odd-numbered transmitter driver 150-11 that sequentially provides the transmitter signals EM(1), EM(2), EM(3), etc. to odd-numbered transmitter lines EL(1), EL(3), EL(5), etc., and an even-numbered transmitter driver 150-12 that sequentially provides the transmitter signals EM(1), EM(2), EM(3), etc. to even-numbered transmitter lines EL(2), EL(4), EL(6), etc., and the odd-numbered transmitter driver 150-11 and the even-numbered transmitter driver 150-12 may simultaneously (or concurrently) provide the transmitter signals EM(1), ..., EM(k) to each of the first to the kth transmitter line groups.

[0073] Here, the odd-numbered transmitter drivers 150-11 can be electrically connected to the odd-numbered transmitter lines EL(1), EL(3), EL(5), etc., and can include a first transmitter stage to a 2k-1 transmitter stage EST(1), EST(3), EST(5), etc., that sequentially generate the first transmitter signal to the kth transmitter signal EM(1), ..., EM(k). When the timing controller 160 applies the transmitter start signal ESP to the first transmitter stage EST(1), the odd-numbered transmitter drivers 150-11 can sequentially provide the first transmitter signal to the kth transmitter signal EM(1), ..., EM(k) to the odd-numbered transmitter lines EL(1), EL(3), EL(5), etc. For example, the first to the 2k-1th transmitter stages EST(1), EST(3), EST(5), etc., included in the odd-numbered transmitter drivers 150-11 can sequentially generate the first transmitter signal to the kth transmitter signal EM(1), ..., EM(k) based on the transmitter start signal ESP (or the output signal of the previous transmitter stage) and the first transmitter clock signal ECLKS(1).

[0074] Furthermore, the even-numbered transmitter drivers 150-12 can be electrically connected to even-numbered transmitter lines EL(2), EL(4), EL(6), etc., and can include second transmitter stages to 2k transmitter stages EST(2), EST(4), EST(6), etc., that sequentially generate the first transmitter signal to the kth transmitter signal EM(1), ..., EM(k). When the timing controller 160 applies the transmitter start signal ESP to the second transmitter stage EST(2), the even-numbered transmitter drivers 150-12 can sequentially provide the first transmitter signal to the kth transmitter signal EM(1), ..., EM(k) to the even-numbered transmitter lines EL(2), EL(4), EL(6), etc. For example, the second to 2kth transmitter stages EST(2), EST(4), EST(6), etc., included in the even-numbered transmitter drivers 150-12 can sequentially generate the first to the kth transmitter signals EM(1), ..., EM(k) based on the transmitter start signal ESP (or the output signal of the previous transmitter stage) and the second transmitter clock signal ECLKS(2). According to some example embodiments, the first transmitter clock signal ECLKS(1) can be the same as the second transmitter clock signal ECLKS(2), and therefore, the first transmitter clock signal ECLKS(1) and the second transmitter clock signal ECLKS(2) can be shared by the odd-numbered transmitter drivers 150-11 and the even-numbered transmitter drivers 150-12.

[0075] The timing controller 160 can simultaneously (or concurrently) apply the transmit start signal ESP to the first transmit stage EST (1) of the odd-numbered transmit driver 150-11 and the second transmit stage EST (2) of the even-numbered transmit driver 150-12. For example, the first transmitter stage EST(1) and the second transmitter stage EST(2) can simultaneously (or concurrently) apply the first transmit signal EM(1) to the first transmitter line group (i.e., the first transmitter line EL(1) and the second transmitter line EL(2)), the third transmitter stage EST(3) and the fourth transmitter stage EST(4) can simultaneously (or concurrently) apply the second transmit signal EM(2) to the second transmitter line group (i.e., the third transmitter line EL(3) and the fourth transmitter line EL(4)), the fifth transmitter stage EST(5) and the sixth transmitter stage EST(6) can simultaneously (or concurrently) apply the third transmit signal EM(3) to the third transmitter line group (i.e., the fifth transmitter line EL(5) and the sixth transmitter line EL(6)), and the 2k-1 transmitter stage EST(2k-1) and the 2k transmitter stage EST(2k) can simultaneously (or concurrently) apply the k transmit signal EM(k) to the k transmitter line group (i.e., the 2k-1 transmitter line EL(2k-1) and the 2k transmitter line EL(2k)).

[0076] Figure 7 The illustration includes Figure 1 A block diagram of another example of an emission driver in an organic light-emitting display device.

[0077] Reference Figure 7 The transmitter driver 150-2 can be electrically connected to the transmitter lines EL(1), EL(2), EL(3), EL(4), EL(5), EL(6), etc. of the display panel 110. Here, the transmitter lines EL(1), EL(2), EL(3), EL(4), EL(5), EL(6), etc. can be grouped according to two adjacent transmitter lines to form transmitter line groups. For example, the first transmitter line EL(1) and the second transmitter line EL(2) can form the first transmitter line group, the third transmitter line EL(3) and the fourth transmitter line EL(4) can form the second transmitter line group, the fifth transmitter line EL(5) and the sixth transmitter line EL(6) can form the third transmitter line group, and the 2k-1 transmitter line EL(2k-1) and the 2k transmitter line EL(2k) can form the k-th transmitter line group.

[0078] Transmit driver 150-2 can sequentially provide the first transmit signal to the k-th transmit signal EM(1), ..., EM(k) to the first transmit line group to the k-th transmit line group. Here, as... Figure 7 As illustrated in the diagram, each of the first to kth transmitter groups may include odd-numbered transmitter lines EL(1), EL(3), EL(5), etc., and even-numbered transmitter lines EL(2), EL(4), EL(6), etc., and the odd-numbered transmitter lines EL(1), EL(3), EL(5), etc. may be electrically connected to the even-numbered transmitter lines EL(2), EL(4), EL(6), etc. In this case, the transmitter driver 150-2 may be electrically connected to the first to kth transmitter groups and may include a first to kth transmitter stage EST(1), ..., EST(k) that sequentially generates the first to kth transmitter signals EM(1), ..., EM(k). When the timing controller 160 applies the transmit start signal ESP to the first transmitter stage EST(1), the transmitter driver 150-2 may sequentially provide the first to kth transmitter signals EM(1), ..., EM(k) to the first to kth transmitter groups. For example, the first to the kth transmitter stages EST(1), ..., EST(k) included in the transmitter driver 150-2 can sequentially generate the first transmitter signal to the kth transmitter signal EM(1), ..., EM(k) based on the transmitter start signal ESP (or the output signal of the previous transmitter stage) and the transmitter clock signal ECLKS.

[0079] For example, the first transmitter stage EST(1) can simultaneously (or concurrently) apply the first transmit signal EM(1) to the first transmit line group (i.e., the first transmit line EL(1) and the second transmit line EL(2)), the second transmitter stage EST(2) can simultaneously (or concurrently) apply the second transmit signal EM(2) to the second transmit line group (i.e., the third transmit line EL(3) and the fourth transmit line EL(4)), the third transmitter stage EST(3) can simultaneously (or concurrently) apply the third transmit signal EM(3) to the third transmit line group (i.e., the fifth transmit line EL(5) and the sixth transmit line EL(6)), and the k-th transmitter stage EST(k) can simultaneously (or concurrently) apply the k-th transmit signal EM(k) to the k-th transmit line group (i.e., the 2k-1 transmit line EL(2k-1) and the 2k transmit line EL(2k)).

[0080] Figure 8 The illustration includes Figure 1 A schematic diagram of an example of a scan driver in an organic light-emitting display device.

[0081] Reference Figure 8 The scan driver 135-1 can be electrically connected to the scan lines SL(1), SL(2), SL(3), SL(4), SL(5), SL(6), etc. of the display panel 110. Here, the scan driver 135-1 may include an odd-numbered scan driver 130 and an even-numbered scan driver 140. The odd-numbered scan driver 130 is electrically connected to the odd-numbered scan lines SL(1), SL(3), SL(5), etc. of the scan lines SL(1), SL(2), SL(3), SL(4), SL(5), SL(6), etc. of the display panel 110, and is configured to provide the odd-numbered scan signals SS(1), SS(3), SS(5), etc. to the odd-numbered subframe SF1. The even-numbered scan driver 140 is electrically connected to the even-numbered scan lines SL(2), SL(4), SL(6), etc. of the scan lines SL(1), SL(3), SL(5), etc. of the display panel 110, and is configured to provide even-numbered scan signals SS(2), SS(4), SS(6), etc. to the even-numbered scan lines SL(2), SL(4), SL(6), etc. in the even-numbered subframe SF2.

[0082] For example, such as Figure 8As illustrated, the odd-numbered scan driver 130 may include a first scan level to a 2k-1 scan level SST(1), SST(3), SST(5), etc., that sequentially generate odd-numbered scan signals SS(1), SS(3), SS(5), etc. When the timing controller 160 applies the odd-numbered scan start signal SOSP to the first scan level SST(1) in the odd-numbered subframe SF1, the odd-numbered scan driver 130 may sequentially provide the odd-numbered scan signals SS(1), SS(3), SS(5), etc., to the odd-numbered scan lines SL(1), SL(3), SL(5), etc.

[0083] For example, the first scan level to the 2k-1 scan level SST(1), SST(3), SST(5), etc., included in the odd-numbered scan driver 130 can sequentially generate odd-numbered scan signals SS(1), SS(3), SS(5), etc., based on the odd-numbered scan start signal SOSP (or the output signal of the previous scan level) and the first clock signal SCLKS(1). According to some example embodiments, in the even-numbered subframe SF2, the timing controller 160 may not apply the odd-numbered scan start signal SOSP to the first scan level SST(1), and the first clock signal SCLKS(1) applied to the first scan level to the 2k-1 scan level SST(1), SST(3), SST(5), etc., may have a low voltage level. In this case, the first scan level to the 2k-1 scan levels SST(1), SST(3), SST(5), etc., can be inactive in the even-numbered subframe SF2, and therefore, the organic light-emitting display device 100 can avoid consuming unnecessary power.

[0084] Furthermore, the even-numbered scan driver 140 may include second scan levels to 2k scan levels SST(2), SST(4), SST(6), etc., that sequentially generate even-numbered scan signals SS(2), SS(4), SS(6), etc. When the timing controller 160 applies an even-numbered scan start signal SESP to the second scan level SST(2) in an even-numbered subframe SF2, the even-numbered scan driver 140 may sequentially provide even-numbered scan signals SS(2), SS(4), SS(6), etc., to even-numbered scan lines SL(2), SL(4), SL(6), etc. For example, the second scan levels to 2k scan levels SST(2), SST(4), SST(6), etc., included in the even-numbered scan driver 140 may be sequentially generated based on the even-numbered scan start signal SESP (or the output signal of the previous scan level) and the second clock signal SCLKS(2). According to some example embodiments, in odd-numbered subframes SF1, the timing controller 160 may not apply the even-numbered scan start signal SESP to the second scan level SST(2), and the second clock signal SCLKS(2) applied to the second scan level to the 2k scan level SST(2), SST(4), SST(6), etc., may have a low voltage level. In this case, the second scan level to the 2k scan level SST(2), SST(4), SST(6), etc., may not operate in odd-numbered subframes SF1, and therefore, the organic light-emitting display device 100 may not consume unnecessary power.

[0085] Figure 9 The illustration includes Figure 1 A schematic diagram of another example of a scan driver in an organic light-emitting display device.

[0086] Reference Figure 9 The scan driver 135-2 can be electrically connected to the scan lines SL(1), SL(2), SL(3), SL(4), SL(5), SL(6), etc. of the display panel 110. Here, the scan driver 135-2 can include an odd-numbered scan driver 130 and an even-numbered scan driver 140. The odd-numbered scan driver 130 can be electrically connected to the odd-numbered scan lines SL(1), SL(3), SL(5), etc. of the scan lines SL(1), SL(2), SL(3), SL(4), SL(5), SL(6), etc. of the display panel 110.

[0087] The odd-numbered scan driver 130 can provide odd-numbered scan signals SS(1), SS(3), SS(5), etc., to odd-numbered scan lines SL(1), SL(3), SL(5), etc., in the odd-numbered subframe SF1. The even-numbered scan driver 140 can be electrically connected to the even-numbered scan lines SL(2), SL(4), SL(6), etc., among the scan lines SL(1), SL(2), SL(3), SL(4), SL(5), SL(6), etc., of the display panel 110. The even-numbered scan driver 140 can provide even-numbered scan signals SS(2), SS(4), SS(6), etc., to even-numbered scan lines SL(2), SL(4), SL(6), etc., in the even-numbered subframe SF2. Figure 8 Unlike the scan driver 135-1, the odd-numbered scan driver 130 and the even-numbered scan driver 140 of the scan driver 135-2 can share the clock signal SCLKS.

[0088] In other words, with Figure 8 Compared to the structure of the scan driver 135-1, the structure of the scan driver 135-2 can be simplified. However, the organic light-emitting display device 100 including the scan driver 135-2 can perform display operations without selectively using different driving frequencies (e.g., it can operate selectively without using a driving frequency of 60Hz or 120Hz). In other words, the organic light-emitting display device 100 including the scan driver 135-2 can perform display operations only at a specific driving frequency (e.g., a driving frequency of 120Hz).

[0089] Figure 10A and Figure 10B It is shown in the diagram. Figure 1 A schematic diagram illustrating an example of an organic light-emitting display device switching and outputting a scanning signal.

[0090] Reference Figure 10A and Figure 10B The pulse width of the odd-numbered scan start signal SOSP can be greater than the pulse width of the odd-numbered scan signals SS(1), SS(3), SS(5), etc., and the pulse width of the even-numbered scan start signal SESP can be greater than the pulse width of the even-numbered scan signals SS(2), SS(4), SS(6), etc. For example, Figure 10AAs illustrated in the figure, when the timing controller 160 provides the odd-numbered scan start signal SOSP with an increased pulse width to the odd-numbered scan driver 130, the odd-numbered scan driver 130 can switch and output odd-numbered scan signals SS(1), SS(3), SS(5), etc. Here, the effective pulse synchronized with the odd-numbered subframe data S1, S3, S5, etc. can be the last pulse of the odd-numbered scan signals SS(1), SS(3), SS(5), etc. (i.e., Figure 10A The third pulse of the odd-numbered scan signals SS(1), SS(3), SS(5), etc. in the display panel 110, and the driving deviation of the driving transistors included in the pixels 111 in the display panel 110 can be compensated by the remaining pulse.

[0091] In addition, such as Figure 10B As illustrated in the figure, when the timing controller 160 provides the even-numbered scan start signal SESP with an increased pulse width to the even-numbered scan driver 140, the even-numbered scan driver 140 can switch and output even-numbered scan signals SS(2), SS(4), SS(6), etc. Here, the effective pulse synchronized with the even-numbered subframe data S2, S4, S6, etc. can be the last pulse of the even-numbered scan signals SS(2), SS(4), SS(6), etc. (i.e., Figure 10B The third pulse of the even-numbered scan signals SS(2), SS(4), SS(6), etc. in the display panel 110, and the driving deviation of the driving transistors included in the pixels 111 in the display panel 110 can be compensated by the remaining pulse. Because Figure 10A and Figure 10B The switching patterns of the odd-numbered scan signals SS(1), SS(3), SS(5) and the even-numbered scan signals SS(2), SS(4), SS(6) shown are examples. Therefore, the number of pulses, pulse width, etc. of the odd-numbered scan signals SS(1), SS(3), SS(5) and the even-numbered scan signals SS(2), SS(4), SS(6) can be changed in various ways as needed.

Processor 1010 can be a microprocessor, central processing unit (CPU), application processor (AP), etc. Processor 1010 can be coupled to other components via address bus, control bus, data bus, etc. Furthermore, processor 1010 can be coupled to an expansion bus such as a peripheral component interconnect (PCI) bus. Memory device 1020 can store data used for the operation of electronic device 1000. For example, memory device 1020 may include at least one non-volatile memory device (such as an erasable programmable read-only memory (EPROM) device, an electrically erasable programmable read-only memory (EEPROM) device, a flash memory device, a phase-change random access memory (PRAM) device, a resistive random access memory (RRAM) device, a nano-floating gate memory (NFGM) device, a polymer random access memory (PoRAM) device, a magnetic random access memory (MRAM) device, a ferroelectric random access memory (FRAM) device, etc.), and / or at least one volatile memory device (such as a dynamic random access memory (DRAM) device, a static random access memory (SRAM) device, a mobile DRAM device, etc.). Storage device 1030 may include a solid-state drive (SSD) device, a hard disk drive (HDD) device, a CD-ROM device, etc. I / O device 1040 may include input devices (such as a keyboard, keypad, mouse device, touchpad, touch screen, etc.) and output devices (such as a printer, speaker, etc.). According to some example embodiments, I / O device 1040 may include an organic light-emitting display device 1060. Power supply 1050 can provide power for the operation of electronic device 1000.

[0095] The organic light-emitting display device 1060 can display an image corresponding to the visual information of the electronic device 1000. The organic light-emitting display device 1060 can be coupled to other components via a bus or other communication link. The organic light-emitting display device 1060 can selectively perform display operations at different driving frequencies (e.g., it can selectively operate at a driving frequency of 60 Hz or 120 Hz). Here, the organic light-emitting display device 1060 may include a display panel, a data driver, odd-numbered scan drivers, even-numbered scan drivers, an emission driver, and a timing controller. The display panel may include multiple pixels. The data driver can be electrically connected to a data line. Here, when the organic light-emitting display device 1060 operates at a first driving frequency (i.e., a relatively low driving frequency), the data driver can provide frame data for implementing a frame to the data line in one frame. On the other hand, when the organic light-emitting display device 1060 operates at a second driving frequency (i.e., a relatively high driving frequency), the data driver can divide a frame into odd-numbered subframes and even-numbered subframes, divide frame data used to implement a frame into odd-numbered subframe data and even-numbered subframe data, provide odd-numbered subframe data to the data lines in odd-numbered subframes, and provide even-numbered subframe data to the data lines in even-numbered subframes. The odd-numbered scan driver can be electrically connected to the odd-numbered scan lines among the scan lines. The even-numbered scan driver can be electrically connected to the even-numbered scan lines among the scan lines. Here, when the organic light-emitting display device 1060 operates at a first driving frequency, the scan drivers (i.e., the odd-numbered scan drivers and the even-numbered scan drivers) can sequentially provide scan signals (i.e., odd-numbered scan signals and even-numbered scan signals) to the scan lines within a frame. On the other hand, when the organic light-emitting display device 1060 operates at the second driving frequency, the odd-numbered scan drivers can sequentially provide odd-numbered scan signals to odd-numbered scan lines in odd-numbered subframes, and the even-numbered scan drivers can sequentially provide even-numbered scan signals to even-numbered scan lines in even-numbered subframes. Here, when the organic light-emitting display device 1060 operates at the first driving frequency, the emission drivers can sequentially provide emission signals to emission line groups formed by grouping emission lines according to two adjacent emission lines within a frame. On the other hand, when the organic light-emitting display device 1060 operates at the second driving frequency, the emission drivers can sequentially provide emission signals to emission line groups formed by grouping emission lines according to two adjacent emission lines in both odd-numbered and even-numbered subframes. The timing controller can control the data driver, the odd-numbered scan drivers, the even-numbered scan drivers, and the emission drivers.Since the organic light-emitting display device 1060 has been described above, its related descriptions will not be repeated.
