Description

[0001] Cross-reference to related applications

[0002] This application claims priority and benefit to Korean Patent Application No. 10-2024-0063925, filed on May 16, 2024, with the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] The embodiments of this disclosure relate to pixels and display devices including the pixels. Background Technology

[0004] Recently, interest in information displays has increased. Accordingly, research and development of display devices have been ongoing. A display device includes multiple pixels connected to data lines and scan lines. Each pixel includes a pixel circuit and a light-emitting element. The light-emitting element emits light with a predetermined brightness corresponding to the drive current supplied from the drive transistor through the pixel circuit.

[0005] Each pixel may include at least two subpixels for displaying colors different from each other. When a single subpixel for representing a color is set in a pixel, the quality of the image displayed by the display device may degrade when that single subpixel fails.

[0006] The information disclosed in this background section is intended to enhance the understanding of the background of this disclosure, and therefore may contain information that does not constitute prior art. Summary of the Invention

[0051] In the following description, embodiments will be illustrated in more detail with reference to the accompanying drawings, in which the same reference numerals refer to the same elements throughout. However, this disclosure may be implemented in a variety of different forms and should not be construed as being limited to the embodiments illustrated herein. Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete and will fully convey the aspects and features of this disclosure to those skilled in the art. Accordingly, processes, elements, and techniques that are unnecessary for those skilled in the art to fully understand the aspects and features of this disclosure may not be described. Unless otherwise stated, the same reference numerals denote the same elements throughout the drawings and written description, and therefore, redundant descriptions may not be repeated.

[0052] When an embodiment can be implemented differently, the specific process sequence may differ from the described sequence. For example, two consecutively described processes may be performed simultaneously or substantially simultaneously, or in the reverse order of their description.

[0053] Furthermore, as will be understood by those skilled in the art, when the disclosure is considered as a whole, various suitable features of the various embodiments of the disclosure may be combined in part or in whole, or may be combined with each other, and may be technically interlocked and operated in a variety of suitable ways, and unless otherwise stated or implied, the various embodiments may be implemented independently of each other or in any suitable combination with each other.

[0054] In the accompanying drawings, for clarity, the relative dimensions, thicknesses, and ratios of elements, layers, and regions may be exaggerated and / or simplified. For ease of illustration, spatial relative terms such as “below,” “under,” “below,” “below,” “above,” and “above” may be used herein to describe the relationship of one element or feature as illustrated in the drawings to another (or other) element or feature. It will be understood that, in addition to the orientations depicted in the drawings, spatial relative terms are intended to include different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as “below,” “below,” or “under” other elements or features will then be oriented “above” that other element or feature. Thus, the example terms “below” and “below” can include both above and below orientations. The device may be oriented in other ways (e.g., rotated 90 degrees or oriented in other ways), and the spatial relative descriptive terms used herein should be interpreted accordingly.

[0055] Furthermore, it should be anticipated that the shapes shown in the figures may vary in practice depending on, for example, tolerances and / or manufacturing techniques. Accordingly, the embodiments of this disclosure should not be construed as limited to the specific shapes shown in the figures, and should be interpreted in light of possible changes in shape, for example, due to manufacturing processes. Thus, the shapes shown in the figures may not depict the actual shape of an area of ​​the device, and this disclosure is not limited thereto.

[0056] Additionally, embodiments of this disclosure can be described with reference to schematic diagrams of preferred embodiments (and intermediate structures) such that variations in the shapes shown may be anticipated due to, for example, manufacturing techniques and / or tolerances. Therefore, this disclosure should not be limited to the specific shapes of the regions shown herein, but should include shape deviations caused by, for example, manufacturing techniques. The regions shown in the figures are schematic in nature, and their shapes may not represent the actual shapes of the regions of the device.

[0057] In the accompanying drawings, the first direction D1, the second direction D2, and the third direction are not limited to directions corresponding to the three axes of the Cartesian coordinate system, and can be interpreted in a broader sense. For example, the first direction D1, the second direction D2, and the third direction can be perpendicular or substantially perpendicular to each other, or they can represent directions that are not perpendicular to each other and are different from each other.

[0058] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, areas, layers, and / or parts, these elements, components, areas, layers, and / or parts should not be limited by these terms. These terms are used to distinguish one element, component, area, layer, or part from another element, component, area, layer, or part. Therefore, the first element, component, area, layer, or part described below may be referred to as the second element, component, area, layer, or part without departing from the spirit and scope of this disclosure.

[0059] It will be understood that when an element or layer is referred to as being "on," "connected to," or "attached to" another element or layer, it can be directly on, directly connected to, or directly attached to that other element or layer, or one or more intermediary elements or layers may exist. Similarly, when a layer, area, or element is referred to as being "electrically connected" to another layer, area, or element, it can be directly electrically connected to that other layer, area, or element, or it can be indirectly electrically connected to that other layer, area, or element with one or more intermediary layers, areas, or elements located therebetween. Furthermore, it will be understood that when an element or layer is referred to as being "between" two elements or layers, it can be the only element or layer between those two elements or layers, or one or more intermediary elements or layers may exist.

[0060] The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit this disclosure. As used herein, the singular form “a” is intended to include the plural form as well, unless the context clearly indicates otherwise. It will be further understood that, when used in this specification, the terms “comprising,” “including,” “having,” and variations thereof indicate the presence of a stated feature, integral, step, operation, element, and / or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. For example, the expression “A and / or B” means A, B, or A and B. When an expression such as “at least one of…” follows a list of elements, it modifies the entire list of elements without modifying any individual elements in the list. For example, the expressions “at least one of a, b, and c” and “at least one selected from the group consisting of a, b, and c” indicate only a, only b, only c, both a and b, both a and c, both b and c, all of a, b, and c, or variations thereof.

[0061] As used herein, the terms “basically,” “approximately,” and similar terms are used as approximate terms rather than terms of degree and are intended to describe the inherent biases of measured or calculated values ​​that will be recognized by those skilled in the art. Furthermore, when describing embodiments of this disclosure, the use of “may” refers to “one or more embodiments of this disclosure.” As used herein, the terms “use” and variations thereof may be considered synonymous with the terms “utilize” and variations thereof, respectively.

[0062] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will be further understood that terms (such as those defined in common dictionaries) shall be interpreted as having the same meaning as they have in the context of the relevant technology and / or this specification, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0063] Figure 1 This is a block diagram illustrating a display device according to an embodiment.

[0064] Reference Figure 1 The display device DD may include a display panel DP and a display panel driver. The display panel driver may include a gate driver 120, a data driver 130, a voltage generator 140, and a main controller 150.

[0065] The display panel DP may include sub-pixels SP. Sub-pixels SP can be connected to gate driver 120 via first gate line GL1 to m-th gate line GLm, where m is an integer greater than 1. Sub-pixels SP can be connected to data driver 130 via first data line DL1 to n-th data line DLn, where n is an integer greater than 1.

[0066] Subpixels (SPs) can generate light of two or more colors. For example, each subpixel SP can generate light of red, green, blue, cyan, magenta, yellow, and / or white.

[0067] Two or more subpixels SP can constitute a pixel (e.g., a pixel) PXL. For example, as... Figure 1 As shown, pixel PXL may include three sub-pixels SP, but this disclosure is not limited thereto. Thus, pixel PXL can emit light of various suitable colors with various desired brightness based on the combination of light emitted from the sub-pixels SP included therein.

[0068] The gate driver 120 can be connected to sub-pixels SP arranged in the row direction via first gate lines GL1 to m-th gate lines GLm. The gate driver 120 can output gate signals to the first gate lines GL1 to m-th gate lines GLm in response to a gate control signal GCS. In some embodiments, the gate control signal GCS may include a start signal indicating the start of each frame and a horizontal synchronization signal, etc.

[0069] The gate signal may include a first transmit signal, a second transmit signal, a first compensation signal, a second compensation signal, and an initialization gate signal, which will be described in more detail below.

[0070] The gate driver 120 may be disposed on one side of the display panel DP. However, this disclosure is not limited thereto. For example, the gate driver 120 may be divided into two or more drivers that are physically and / or logically separated from each other, and these drivers may be disposed on one side of the display panel DP and on the opposite side of the display panel DP (e.g., opposite side). Thus, in some embodiments, the gate driver 120 may be disposed on the periphery of the display panel DP in various suitable forms.

[0071] Data driver 130 can be connected to sub-pixels SP arranged in the column direction via first data lines DL1 to nth data lines DLn. Data driver 130 can receive image data DATA and data control signal DCS from master controller 150. Data driver 130 can operate in response to data control signal DCS. In some embodiments, data control signal DCS may include source start pulse, source shift clock, and source output enable signal, etc.

[0072] Data driver 130 can receive voltage from voltage generator 140. Data driver 130 can use the received voltage to apply a data signal having a grayscale voltage (e.g., grayscale value or grayscale level) corresponding to image data DATA to first data lines DL1 through nth data lines DLn. When a gate signal is applied to each of the first gate lines GL1 through mth gate lines GLm, a data signal corresponding to image data DATA can be applied to the first data lines DL1 through nth data lines DLn. Accordingly, selected sub-pixels SP can generate light corresponding to the data signal. Thus, an image can be displayed on display panel DP.

[0073] In some embodiments, the gate driver 120 and the data driver 130 may include complementary metal-oxide-semiconductor (CMOS) circuit elements.

[0074] Voltage generator 140 can operate in response to a voltage control signal VCS from main controller 150. Voltage generator 140 can generate multiple voltages and can supply the generated voltages to components of display device DD, such as gate driver 120, data driver 130, and main controller 150. Voltage generator 140 can generate multiple voltages by receiving input voltages from outside the display device DD and adjusting the received input voltages.

[0075] Voltage generator 140 can generate a first electrical voltage and a second electrical voltage. The generated first and second electrical voltages can be provided to the sub-pixel SP via the power line PL. In other embodiments, at least one of the first and second electrical voltages can be provided from outside the display device DD.

[0076] Thus, voltage generator 140 can provide various voltages and / or signals. For example, voltage generator 140 can provide one or more initialization voltages applied to sub-pixel SP. For example, in a sensing operation for sensing the electrical characteristics of the transistors and / or light-emitting elements of sub-pixel SP, a reference voltage (e.g., a predetermined reference voltage) can be applied to the first data lines DL1 to the nth data lines DLn. Voltage generator 140 can generate the reference voltage and can transmit the reference voltage to data driver 130. For example, in a display operation for displaying an image on display panel DP, a common pixel control signal can be applied to sub-pixel SP, and voltage generator 140 can generate the pixel control signal. In some embodiments, voltage generator 140 can provide the pixel control signal to sub-pixel SP via pixel control line PXCL. Figure 1 The illustration shows a pixel control line PXCL connected between the voltage generator 140 and the display panel DP. However, this disclosure is not limited to this. For example, the pixel control line PXCL can be connected between the gate driver 120 and the display panel DP. In this case, pixel control signals can be transmitted from the voltage generator 140 to the pixel control line PXCL via the gate driver 120.

[0077] The main controller 150 can control the overall operation of the display device DD. The main controller 150 can receive input image data IMG and its corresponding input control signal CTRL from an external source. The main controller 150 can provide an output control signal CS in response to the input control signal CTRL. For example, the main controller 150 can provide a gate control signal GCS, a data control signal DCS, and a voltage control signal VCS in response to the input control signal CTRL.

[0078] The main controller 150 can convert the input image data IMG into a format suitable for a display device DD or display panel DP (e.g., its specifications), thereby outputting image data DATA. In some embodiments, the main controller 150 can arrange the input image data IMG in rows to fit sub-pixels SP, thereby outputting image data DATA.

[0079] Two or more of the components, including the data driver 130, the voltage generator 140, and the main controller 150, can be mounted on a single integrated circuit (IC). For example... Figure 1 As shown, the data driver 130, voltage generator 140, and main controller 150 may be included in a driver integrated circuit (DIC). The data driver 130, voltage generator 140, and main controller 150 may be functionally separate components within a single driver integrated circuit (DIC). In other embodiments, at least one of the data driver 130, voltage generator 140, and main controller 150 may be provided as a component (e.g., a circuit element or IC) to be distinguished from (e.g., separated from) the driver integrated circuit (DIC).

[0080] Figure 2 The illustration is based on an embodiment. Figure 1 A bounding box for any subpixel. Figure 2 In the middle, refer to the above. Figure 1 The ij-th subpixel SPij, arranged in the i-th row (where i is an integer greater than or equal to 1 and less than or equal to m) and j-th column (where j is an integer greater than or equal to 1 and less than or equal to n) of the described subpixel SP, is illustrated as a representative example.

[0081] Reference Figure 2 Subpixel SPij may include subpixel circuit SPC and light-emitting element LD.

[0082] The light-emitting element (LD) can be connected between the first voltage node VDDN and the second voltage node VSSN. The first voltage node VDDN is connected to the reference above. Figure 1 One of the power lines PL is described to receive a first power voltage. A second power voltage node VSSN is connected to the other power line PL to receive a second power voltage. The first power voltage may have a higher voltage level than the second power voltage.

[0083] The light-emitting element LD is connected between the anode electrode AE ​​and the cathode electrode CE. The anode electrode AE ​​can be connected to the first power voltage node VDDN via a sub-pixel circuit SPC. For example, the anode electrode AE ​​can be connected to the first power voltage node VDDN via one or more transistors included in the sub-pixel circuit SPC. The cathode electrode CE can be connected to the second power voltage node VSSN. The light-emitting element LD emits light according to the current flowing from the anode electrode AE ​​to the cathode electrode CE.

[0084] The sub-pixel circuit SPC can be connected to the reference above. Figure 1 The description refers to the i-th gate line GL1 to the m-th gate line GLm and the j-th data line DLj among the first data lines DL1 to the n-th data lines DLn. In response to a gate signal received via the i-th gate line GL1, the sub-pixel circuit SPC can control the light-emitting element LD to emit light according to a data signal received via the j-th data line DLj. In some embodiments, the sub-pixel circuit SPC may be further connected to the above-described reference... Figure 1 The pixel control line PXCL is described. The sub-pixel circuit SPC can further control the light-emitting element LD in response to the pixel control signal received through the pixel control line PXCL.

[0085] For such operation, the sub-pixel circuit (SPC) may include circuit elements such as multiple transistors and one or more capacitors.

[0086] The transistors of the sub-pixel circuit SPC may include P-type transistors and / or N-type transistors. In some embodiments, the transistors of the sub-pixel circuit SPC may include metal-oxide-semiconductor field-effect transistors (MOSFETs). In some embodiments, the transistors of the sub-pixel circuit SPC may include amorphous silicon semiconductors, monocrystalline silicon semiconductors, polycrystalline silicon semiconductors, and / or oxide semiconductors, etc.

Figure 3 A planar image of pixels within pixels. For example, Figures 4 to 7 Can be illustrated Figure 3 Various examples of the mn-th pixel PXLmn among the pixels.

[0088] Reference Figure 3 According to one or more embodiments of this disclosure, multiple pixels PXL (e.g., see...) Figure 1 ) can be set in the display panel DP. For example, the pixel PXL set in the display panel DP can be arranged along the first direction D1 and / or the second direction D2. Figure 3 The display panel DP shown above can be compared with the one referenced above. Figure 1 The description corresponds to the display panel DP.

[0089] Each of the multiple pixels PXL can include one or more sub-pixels SP1, SP2, and SP3.

For example, the first sub-pixel SP1_1, the first sub-pixel SP1_2, the second sub-pixel SP2_1, the second sub-pixel SP2_2, and the third sub-pixel SP3 can be arranged sequentially along the first direction D1. In other words, the first sub-pixel SP1_2 can be positioned between the first sub-pixel SP1_1 and the second sub-pixel SP2_1. Additionally, the second sub-pixel SP2_2 can be positioned between the second sub-pixel SP2_1 and the third sub-pixel SP3. The first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 can be positioned side-by-side with each other along the first direction D1.

For example, the third sub-pixel SP3 may have an "L" shape reversed in the first direction D1 and may surround a portion of the side of the second sub-pixel SP2_2 (e.g., around its periphery).

Figure 4 A planar diagram of the state of the subpixels of a pixel during the first time period. Figure 10 It is shown in the diagram. Figure 4 A planar diagram of the state of the subpixels of the pixel being driven during the second time period. Figure 11 It is a graph illustrating the brightness retention coefficient curves of pixels according to the first embodiment, the second embodiment, and the comparative example.

[0109] Reference Figures 8 to 10 The main controller 150 may include a memory 151, an aging determiner 152, and a signal generator 153. The main controller 150 may be configured to control the sub-pixel SP based on the driving data OD and aging data of the sub-pixel SP.

[0110] Memory 151 may include storage of data contained in pixel PXL (e.g., see [link]). Figure 1 Subpixels SP in ) (e.g., see Figure 1 A lookup table (LUT) for aging data is used for each of the sub-pixels SP1, SP2, and SP3. For example, the lifetimes of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 can be different from each other. Aging data for the lifetime of each of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 can be stored in the lookup table. The aging data can include information about the threshold lifetime for each of the sub-pixels SP. The threshold lifetime can be the point in time when each of the sub-pixels SP does not emit light at the desired brightness. For example, this will be referred to below. Figures 8 to 10 Together Figure 11 To describe in more detail: Threshold lifetime can be the point in time when the luminance retention factor of each of the sub-pixels SP decreases to 90% or less.

[0111] The aging determiner 152 can accumulate the driving time of each sub-pixel SP included in pixel PXL. For example, the aging determiner 152 can measure the time it takes for pixel PXL to be driven until a specific time point. Accordingly, the aging determiner 152 can generate driving data OD at the driving time point of each sub-pixel SP. The aging determiner 152 can transmit the driving data OD to the signal generator 153.

[0112] Signal generator 153 can read data from a lookup table included in memory 151. For example, signal generator 153 can read aging data included in the lookup table. Signal generator 153 can be supplied with driving data OD. Accordingly, signal generator 153 can convert the input control signal CTRL into an output control signal CS for controlling sub-pixels SP respectively, based on the aging data and driving data OD.

[0113] Reference Figure 9 and Figure 10 The sub-pixel SP of the mn-th pixel PXLmn (for example, see Figure 1 At least one of the sub-pixels SP1_1, SP2_1, and SP3 of the mn-th pixel PXLmn can be driven, and at least another sub-pixel SP of the mn-th pixel PXLmn can be de-driven. For example, during the first time period P1, sub-pixels SP1_1, SP2_1, and SP3 can be driven. During the first time period P1, sub-pixels SP1_2 and SP2_2 can be de-driven. Additionally, during the second time period P2, sub-pixels SP1_2, SP2_2, and SP3 can be driven. During the second time period P2, sub-pixels SP1_1 and SP2_1 can be de-driven.

[0114] In the following text, for ease of explanation, the driver above will be described in more detail. Figure 4 The embodiment described above, which describes a sub-pixel SP of the mn-th pixel PXLmn, is a representative example. However, this disclosure is not limited thereto. For example, reference above... Figures 5 to 7 The sub-pixels SP of each mn-th pixel PXLmn described in the text can also be applied equivalently or substantially equivalently.

[0115] According to the first embodiment, when only two or more sub-pixels SP that represent the same color as each other are driven (e.g., see...), Figure 1 Any one of the following, and the corresponding subpixel SP is driven until its threshold lifetime, can drive two or more subpixel SPs that represent the same color as each other (e.g., see [link]). Figure 1 Another one in ). For example, during the first time period P1, sub-pixels SP1_1 (1_1), SP2_1 (2_1), and SP3 (3_3) can be driven, while sub-pixels SP1_2 (1_2) and SP2_2 (2_2) can be de-driven. Then, during the second time period P2, sub-pixels SP1_2 (1_2), SP2_2 (2_2), and SP3 (3_3) can be driven, while sub-pixels SP1_1 (1_1) and SP2_1 (2_1) can be de-driven.

[0116] In other words, signal generator 153 can generate an output control signal CS such that sub-pixel SP1_1 and sub-pixel SP2_1 are driven during a first time period P1. The first time period P1 can be a time interval equal to or substantially equal to the threshold lifetime of each of sub-pixels SP1_1 and SP2_1. In other words, signal generator 153 can determine the first time period P1 to correspond to the threshold lifetime of each of sub-pixels SP1_1 and SP2_1. Subsequently, signal generator 153 can generate an output control signal CS such that sub-pixels SP1_2 and SP2_2 are driven during a second time period P2 following the first time period P1.

[0117] According to the second embodiment, each of the first time period P1 and the second time period P2 can correspond to one frame. For example, sub-pixel SP1_1 and sub-pixel SP1_2 can be driven alternately for each frame. In addition, sub-pixel SP2_1 and sub-pixel SP2_2 can be driven alternately for each frame.

[0118] In other words, signal generator 153 can define the first time period P1 as a single frame. Signal generator 153 can define the next frame after the first time period P1 as the second time period P2. Accordingly, signal generator 153 can generate an output control signal CS such that sub-pixels SP1_1 and SP2_1 are driven in the first time period P1 as a single frame, and sub-pixels SP1_2 and SP2_2 are driven in the second time period P2 as the next frame.

[0119] Sub-pixels SP1_1 and SP1_2 can emit light with the same or substantially the same brightness as each other. In other words, even when the brightness represented by pixel PXL remains unchanged, sub-pixels SP1_1 and SP1_2 can be driven in the manner described above. Additionally, sub-pixels SP2_1 and SP2_2 can emit light with the same or substantially the same brightness as each other.

[0120] Reference Figure 11 The diagram shows the representation based on pixel PXL (e.g., see...). Figure 1 The brightness retention coefficient curve of any one of the driving times is shown in the GP graph. For example, in Figure 11The figures in the middle are a brightness retention coefficient curve GP1 of pixel PXL according to the first embodiment, a brightness retention coefficient curve GP2 of pixel PXL according to the second embodiment, and a brightness retention coefficient curve GP3 of pixel PXL according to the comparative example.

[0121] During the driving period OP, the luminance retention coefficient of pixel PXL according to the comparative example can continuously decrease. For example, the luminance retention coefficient of pixel PXL according to the comparative example at the second time point T2 can be 90%. In addition, the luminance retention coefficient of pixel PXL according to the comparative example at the third time point T3 can be 80%. The threshold lifetime of pixel PXL according to the comparative example can be the time interval from the first time point T1 to the second time point T2.

[0122] According to the first embodiment, the first sub-pixel SP1_1, the second sub-pixel SP2_1, and the third sub-pixel SP3 can be driven during the first driving period OP1. The luminance retention coefficient of pixel PXL according to the first embodiment at the second time point T2 can be 90%. The first driving period OP1 can correspond to the threshold lifetime of each of the first sub-pixel SP1_1 and the second sub-pixel SP2_1. Subsequently, the first sub-pixel SP1_1 and the second sub-pixel SP2_1 can be undriven during the second driving period OP2. For example, the first sub-pixel SP1_1 and the second sub-pixel SP2_1 can be undriven starting from the second time point T2. Accordingly, according to the first embodiment, the luminance retention coefficient of pixel PXL can be maintained at 90% or greater during the driving period OP. In the first embodiment, the first period P1 and the second period P2 can be the same as or substantially the same as the first driving period OP1 and the second driving period OP2, respectively.

[0123] According to the second embodiment, during the driving period OP, sub-pixels SP1_1 and SP1_2 can be driven alternately for each frame. Additionally, during the driving period OP, sub-pixels SP2_1 and SP2_2 can be driven alternately for each frame. Accordingly, compared to the brightness retention coefficient of pixel PXL according to the first embodiment, the brightness retention coefficient of pixel PXL according to the second embodiment can decrease with a relatively small slope. For example, at the second time point T2, the brightness retention coefficient of pixel PXL according to the second embodiment can be 95%. On the other hand, at the second time point T2, the brightness retention coefficient of pixel PXL according to the first embodiment can be 90%. In other words, according to the second embodiment, during the driving period OP, the brightness retention coefficient of pixel PXL can be maintained at 90% or greater. According to the second embodiment, the first period P1 and the second period P2 can be different from the first driving period OP1 and the second driving period OP2, respectively.

[0124] According to embodiments of this disclosure, two or more sub-pixels representing the same color as each other (e.g., sub-pixel SP1_1 and sub-pixel SP1_2) are set in pixel PXL (e.g., see Figure 1 In this way, the display device DD can display images with improved quality for a relatively long time. In other words, the luminance retention factor of pixel PX can be maintained at a relatively high level during the driving period OP. For example, in the display device DD according to the comparative example, a single sub-pixel SP that emits light of the corresponding color (e.g., see...) Figure 1 A sub-pixel SP1_1 and a sub-pixel SP1_2 representing the same color of light are disposed in a pixel PXL and are driven at different points in time. Accordingly, the lifespan of a pixel PXL can be relatively improved compared to a comparative example where individual sub-pixels SP are driven consecutively.

Additionally, sub-pixels SP5_1 and SP5_2 can emit light with the same or substantially the same brightness as each other.
