Description

Technical Field

[0001] This invention relates to display devices. Background Technology

[0002] Typically, display devices have a structure where a scan drive unit is arranged on one side of the pixel section and a data drive unit is arranged on the other side. Recently, structures for display devices that minimize the non-display areas on both sides of the display device are under development. For example, to achieve a narrow bezel, panels using a single-side driving method, where the scan drive unit and the data drive unit are arranged together on one side, are being investigated.

[0003] In this type of single-sided driving display device, the lengths of the scan lines are not the same. Due to this wiring structure, the RC load corresponding to the pixel position is uneven. Furthermore, since the timing of supplying scan signals and data signals to each pixel is asynchronous, a deviation in the data charging rate occurs, which may reduce the display quality. Summary of the Invention

[0004] One object of the present invention is to provide a display device that reduces the charging rate deviation of data signals.

[0005] A display device according to an embodiment of the present invention may include: a pixel unit including pixels connected to data lines and scan lines; a data driving unit disposed on one side of the pixel unit to drive the data lines; a scan driving unit disposed together with the data driving unit on the same side of the pixel unit to drive the scan lines; and a control unit that controls the output timing of the data signals based on the load of the scan signals supplied to the scan lines and the load of the data signals supplied to the data lines, at least one of pixel columns and pixel rows.

[0006] In one embodiment, each of the scan lines may include: a main scan line extending along a first direction and connected to pixels of a corresponding pixel row; a first sub-scan line extending along a second direction different from the first direction and connected to the main scan line at a first contact point; and a second sub-scan line extending along the second direction and connected to the main scan line at a second contact point.

[0007] In one embodiment, the control unit may control the output timing of the data signal according to the distance between the main scan line connected to the pixel and the scan drive unit.

[0008] In one embodiment, the load of the scan signal may increase as the main scan line connected to the pixel moves away from the scan drive unit.

[0009] In one embodiment, for each of the scan lines, the control unit can adjust the output timing of the data signal according to the position of the object pixel connected to the main scan line in the first direction.

[0010] In one embodiment, the control unit may adjust the output timing of the data signal based on the distance between the object pixel and the first contact point and the distance between the object pixel and the second contact point.

[0011] In one embodiment, the load of the scan signal may increase as the distance between the pixel and the first contact point increases or as the distance between the pixel and the second contact point increases.

[0012] In one embodiment, the control unit may control the output timing of the data signal according to the distance between the pixel connected to the data line and the data driving unit.

[0013] In one embodiment, the load of the data signal may increase as the pixel connected to the data line moves away from the data drive unit.

[0014] In one embodiment, the lengths of the first sub-scan line and the second sub-scan line of the scan line may gradually increase in a first direction.

[0015] In one embodiment, the control unit can generate timing control signals for controlling the output timing of the data signals and supply them to the data driving unit.

[0016] In one embodiment, the data driving unit may delay the output timing of the data signal by a positive or negative delay value based on the timing control signal.

[0017] In one embodiment, when the supply timing of the data signal is later than the supply timing of the scan signal, the data driving unit may delay the output timing of the data signal by a negative delay value based on the timing control signal.

[0018] In one embodiment, when the supply timing of the data signal is earlier than the supply timing of the scan signal, the data driving unit may delay the output timing of the data signal by a positive delay value based on the timing control signal.

[0019] In one embodiment, when the supply timing of the data signal is consistent with the supply timing of the scan signal, the data driving unit can output based on the timing control signal without delaying the output timing of the data signal.

[0020] In one embodiment, the control unit can set adjacent pixel rows in a pixel row as a pixel row block, and can control the output timing of the data signal in units of the pixel row blocks.

[0021] In one embodiment, the control unit can set adjacent pixel columns in a pixel column as a pixel column block, and can control the output timing of the data signal in units of the pixel column blocks.

[0022] In one embodiment, the data driving unit can change the length of the horizontal blank period based on the timing control signal.

[0023] In one embodiment, when the length of the horizontal blank time period is increased, the output timing of the data signal can be delayed by the positive delay value.

[0024] In one embodiment, when the length of the horizontal blank time period is reduced, the output timing of the data signal can be delayed by the negative delay value.

[0025] The display device according to an embodiment of the present invention can control the output timing of the data signal based on the load of the scan signal and the load of the data signal. Accordingly, the charging rate deviation of the data signal of the pixels can be reduced, thereby improving the display quality.

[0026] However, the effects of the present invention are not limited to those described above, and various extensions can be made without departing from the concept and scope of the present invention. Attached Figure Description

[0035] This invention can be modified in many ways and can have many forms. Specific embodiments are shown in the accompanying drawings and will be described in detail in the specification. However, it is not intended to limit the invention to the specific disclosed forms, and should be understood to include all modifications, equivalents, and substitutions encompassed within the spirit and scope of the invention.

[0036] In describing the accompanying drawings, similar reference numerals are used for similar constituent elements. For clarity of the invention, the dimensions of the structures are exaggerated in the drawings compared to their actual dimensions. Terms such as "first," "second," etc., can be used to describe multiple constituent elements, but the constituent elements should not be limited by these terms. These terms are used only to distinguish one constituent element from another. For example, without departing from the scope of the invention, a first constituent element may be named a second constituent element, and similarly, a second constituent element may be named a first constituent element. Singular expressions include plural expressions unless the context clearly indicates a different meaning.

[0037] In this application, terms such as “comprising” or “having” should be understood as being intended to specify the presence of features, figures, steps, operations, constituent elements, components or combinations thereof as described in the specification, rather than pre-excluding the presence or possibility of one or more other features or figures, steps, operations, constituent elements, components or combinations thereof.

[0038] Furthermore, when referring to the “connection” between one part and another, it includes not only the case of a direct connection, but also the case of a connection through other elements that are in between the two.

[0039] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0040] Figure 1 This is a block diagram illustrating a display device according to an embodiment of the present invention.

[0041] Reference Figure 1 The display device 1000 may include a pixel unit 100, a scan driving unit 200, a data driving unit 300, and a control unit 400.

[0042] The display device 1000 can be implemented as a self-emissive display device including multiple self-emissive elements. For example, the display device 1000 can be an organic light-emitting display device including organic light-emitting elements or a display device including inorganic light-emitting elements. However, this is only an example, and the display device 1000 can also be implemented as a liquid crystal display device, a quantum dot display device, etc.

[0043] The display device 1000 can be a flat panel display device, a flexible display device, a curved display device, a foldable display device, or a bendable display device. Furthermore, the display device 1000 can be applied to transparent display devices, head-mounted display devices, wearable display devices, etc.

[0044] The pixel unit 100 may include a plurality of pixels PX connected to the scan line S and the data line D. The display device 1000 of this embodiment is a single-side driving display device 1000 in which the data driving unit 300 and the scan driving unit 200 are arranged together on one side of the pixel unit 100. Therefore, a narrow bezel can be achieved, minimizing the non-display areas on both sides of the display device 1000.

[0045] To apply single-sided drive, each scan line S may include a main scan line SM, a first sub-scan line SS1, and a second sub-scan line SS2.

[0046] The main scan line SM can extend along the first direction DR1 and can be connected to the pixel PX of its corresponding pixel row. Scan signals can be supplied to the pixel PX through the main scan line SM. That is, each of the main scan lines SM can define a pixel row.

[0047] The first sub-scan line SS1 may extend along the second direction DR2 and may be connected to the main scan line SM at the first contact point CP1. The second sub-scan line SS2 may extend along the second direction DR2 and may be connected to the main scan line SM at the second contact point CP2. In one embodiment, the second direction DR2 may correspond to the pixel column direction.

[0048] The first sub-scan line SS1 and the second sub-scan line SS2 can be electrically connected to the scan drive unit 200 and the main scan line SM. When a single sub-scan line is connected to the main scan line SM, the RC load (or RC delay) deviation between the portion near the contact point and the portion far from the contact point may increase. To reduce this RC load deviation, the main scan line SM can be connected to the first sub-scan line SS1 and the second sub-scan line SS2, which is separated from the first sub-scan line SS1. That is, since the scan signal is supplied to the main scan line SM through the first contact point CP1 and the second contact point CP2, the RC load deviation according to the position within the main scan line SM can be relatively reduced.

[0049] In one embodiment, the first sub-scan line SS1 can be connected one-to-one with the main scan line SM, and the second sub-scan line SS2 can be connected one-to-one with the main scan line SM. However, the connection relationship between the first sub-scan line SS1 and the second sub-scan line SS2 and the main scan line SM is not limited to this. For example, each of the first sub-scan lines SS1 can be connected to two or more main scan lines SM, and each of the second sub-scan lines SS2 can be connected to two or more main scan lines SM.

[0050] like Figure 1 As shown, the first sub-scan line SS1 and the second sub-scan line SS2 can be arranged in such a way that their lengths gradually increase in the first direction DR1.

[0051] In addition, although Figure 1 The illustration shows a case where each scan line S includes two sub-scan lines (i.e., a first sub-scan line SS1 and a second sub-scan line SS2), but this is merely an example, and the configuration of scan line S is not limited to this. For example, each scan line S may include three or more sub-scan lines. In this case, since the scan signal is supplied to the main scan line SM through three or more contact points, the RC load deviation according to the position within the main scan line SM can be further reduced compared to the case where each scan line S includes two sub-scan lines and the scan signal is supplied to the main scan line SM through two contact points. However, with the increase in the number of sub-scan lines, the number of signal wiring and input / output terminals increases, so it is necessary to appropriately set the number of sub-scan lines included in the scan line S. As an example, each scan line S may include three sub-scan lines. Hereinafter, for ease of explanation, the case where each scan line S includes two sub-scan lines (i.e., a first sub-scan line SS1 and a second sub-scan line SS2) will be used as a reference.

[0052] Data line D can be connected to pixel PX in units of pixel columns.

[0053] The scan drive unit 200 can receive a first control signal SCS from the control unit 400. The scan drive unit 200 can supply scan signals to the scan line S in response to the first control signal SCS (or, a scan control signal). The first control signal SCS may include a scan start signal, a clock signal, etc., for the scan signal.

[0054] The scan signal can be set to a gate on-state (low voltage or high voltage) corresponding to the type (P-type or N-type) of the transistor to which the corresponding scan signal is supplied.

[0055] The data drive unit 300 can receive a second control signal DCS (or a data control signal) from the control unit 400. In response to the second control signal DCS, the data drive unit 300 can convert digital image data RGB into an analog data signal (or a data voltage) and supply the data signal to the data line D.

[0056] Furthermore, as described above, for a pixel row, the RC load of the scan signal may increase as it moves away from the contact point in the first direction DR1, and for a pixel column, the RC load of the scan signal and the data signal may increase as it moves away from the scan drive unit 200 and the data drive unit 300 in the second direction DR2.

[0057] In one embodiment, the output timing of the data signal output from the data driver unit 300 can be adjusted by the control unit 400. For example, the data driver unit 300 can receive a timing control signal TCS from the control unit 400 and adjust the output timing of the data signal output to each data line D in response to the timing control signal TCS.

[0058] The control unit 400 can receive input control signals CON and input image data IDATA from an image source such as an external graphics device. The control unit 400 can generate image data RGB that matches the operating conditions of the pixel unit 100 based on the input image data IDATA and provide it to the data driver unit 300.

[0059] In one embodiment, the control unit 400 may generate a first control signal SCS for controlling the driving timing of the scan drive unit 200 and a second control signal DCS for controlling the driving timing of the data drive unit 300 based on the input control signal CON, and provide them to the scan drive unit 200 and the data drive unit 300 respectively.

[0060] Furthermore, the control unit 400 can generate a timing control signal TCS for adjusting the output timing of the data signal and provide it to the data drive unit 300.

[0061] The control unit 400 can adjust the output timing of the data signal based on the RC load deviation of the position of the scan line S of the supplied scan signal (e.g., the distance from the scan drive unit 200 on the second direction DR2) and the position of the pixel PX connected to the scan line S (e.g., the distance from the contact point on the first direction DR1). Furthermore, the control unit 400 can adjust the output timing of the data signal based on the RC load deviation of the position of the data line D of the supplied data signal (e.g., the distance from the data drive unit 300 on the second direction DR2).

[0062] In one embodiment, the data driving unit 300 can adjust the output timing of the data signal based on a look-up table (LUT) included in the timing control signal TCS provided from the control unit 400. Here, the look-up table (LUT) stores delay values ​​of the data signal based on the relative positions of the pixels PX within the pixel unit 100, and the data driving unit 300 can adjust the output timing of the data signal based on these delay values.

[0063] In one embodiment, the data driving unit 300 can control the output timing of the data signal by changing the length of the horizontal blank period (or horizontal blank field) based on the timing control signal TCS. For this, see [link to relevant documentation]. Figure 10 and Figure 11 Detailed explanation.

[0064] Each pixel PX can be charged with a data voltage corresponding to the data signal. Here, it takes a predetermined time to charge to the data voltage at a specific voltage level, and the charging of the data voltage needs to be completed within the time period during which the scan signal is applied (e.g., one horizontal time period (1H time) or two horizontal time periods (2H time) etc.).

[0065] However, if the supply time of the scan signal to each pixel PX is different from the supply time of the data signal, a deviation in the data charging rate according to the pixel PX may occur.

[0066] For example, in such Figure 1In the wiring structure of the pixel section 100 shown, for a pixel row, the time it takes for the scan signal to be transmitted to the pixel PX of that pixel row can be different due to the RC load of the distance from the first contact point CP1 and the distance from the second contact point CP2. Furthermore, the time it takes for the scan signal to be transmitted to the contact point of each pixel row can be different due to the RC load of the distance from the scan drive section 200 to each pixel row. And, for a pixel column (or a data line D), the time it takes for the data signal to be transmitted to the pixel PX of each pixel row can be different due to the RC load of the distance from the data drive section 300 to each pixel row.

[0067] Therefore, depending on the relative positions of the pixels PX within the pixel unit 100, the timing of the supply of the scan signal and the data signal may be inconsistent, and deviations in the data charging rate may occur, resulting in a decrease in display quality.

[0068] That is, the control unit 400 can adaptively control the output timing of the data signal by reflecting the RC load deviation of the scan signal and the data signal according to the relative position of the pixel PX.

[0069] In addition, although Figure 1 The illustrations show different configurations for the scan driver unit 200, data driver unit 300, and control unit 400, but at least a portion of these units can be integrated into a single module or integrated circuit chip. In one embodiment, at least a portion of the configuration and / or function of the control unit 400 may be included in the data driver unit 300. For example, the data driver unit 300 and the control unit 400 may be included in a single source IC.

[0070] Furthermore, the scan driving unit 200 can be configured using multiple scan driving units (or scan integrated circuits) each responsible for driving a portion of the pixel unit 100. Similarly, the data driving unit 300 can be configured using multiple data driving units (or data integrated circuits) each responsible for driving a portion of the pixel unit 100.

[0071] Figure 2 It is schematically shown that includes Figure 1 An example of a pixel section in a display device.

[0072] Reference Figure 2 Scan lines S1 to Sn (where n is an integer greater than 1) may include main scan lines SM_1 to SM_n, first sub-scan lines SS1_1 to SS1_n and second sub-scan lines SS2_1 to SS2_n.

[0073] For example, the first sub-scan line SS1_i of the i-th scan line Si (where i is a positive integer) can be connected to the main scan line SM_i of the i-th scan line Si through the first contact point CP1, and the second sub-scan line SS2_i of the i-th scan line Si can be connected to the main scan line SM_i of the i-th scan line Si through the second contact point CP2.

[0074] In one embodiment, each of the first sub-scan lines SS1_1 to SS1_n and the second sub-scan lines SS2_1 to SS2_n can be arranged such that its length gradually increases in the first direction DR1. Figure 2 The diagram schematically illustrates the arrangement tendency of the first contact point CPS1 to which the first sub-scan lines SS1_1 to SS1_n are connected, and the arrangement tendency of the second contact point CPS2 to which the second sub-scan lines SS2_1 to SS2_n are connected. For example, the first sub-scan line SS1_1 of the first scan line S1 may be arranged on the right side relative to the first sub-scan line SS1_n of the nth scan line Sn, and the second sub-scan line SS2_1 of the first scan line S1 may be arranged on the right side relative to the second sub-scan line SS2_n of the nth scan line Sn.

[0075] According to this arrangement of the first contact point CPS1 and the second contact point CPS2, the RC load (hereinafter referred to as load) of the scan signals supplied to the scan lines S1 to Sn can be different from each other. According to the arrangement of the first contact point CPS1 and the second contact point CPS2, as the scan signal load moves away from the lower side of the pixel portion 100 in the second direction DR2, the scan signal load can also increase as the scan signal load moves away from the first contact point CPS1 and the second contact point CPS2 in the first direction DR1.

[0076] In addition, as referenced Figure 1 As explained, as the data signal supplied to the data line moves away from the lower side of the pixel unit 100 in the second direction DR2, the RC load may increase.

[0077] In one embodiment, the scan signal and data signal can be supplied on the upper side of the pixel section 100 in the opposite direction to the second direction DR2. For example, the scan signal and data signal can be supplied sequentially from the pixel row corresponding to the first main scan line SM_1 to the pixel row corresponding to the nth main scan line SM_n.

[0078] Figure 3 It shows the connection included in Figure 1 A diagram illustrating an example of scan lines and data lines for pixel rows and columns in a display device.

[0079] exist Figure 3An example is shown with the first pixel row PXR1, the i-th pixel row PXRi, the n-th pixel row PXRn, and the k-th pixel column PXCk (where k is a positive integer). Furthermore, Figure 3 Exemplary examples show scan lines S1, Si, Sn and data lines D1, Dj, Dk, Dl, Dm (where j, l, m are positive integers) connected to pixel rows PXR1, PXRi, PXRn and pixel column PXCk.

[0080] Reference Figure 3 The first pixel row PXR1 can be connected to the first scan line S1, the i-th pixel row PXRi can be connected to the i-th scan line Si, and the n-th pixel row PXRn can be connected to the n-th scan line Sn.

[0081] In one embodiment, the first scan line S1 may include a main scan line SM_1, a first sub-scan line SS1_1, and a second sub-scan line SS2_1. The scan signals supplied to the first sub-scan line SS1_1 and the second sub-scan line SS2_1 can be supplied to the first pixel PX1 to the fifth pixel PX5 of the first pixel row PXR1 via the main scan line SM_1.

[0082] Furthermore, the scan signal supplied to the main scan line SM_1 via the first sub-scan line SS1_1 and the scan signal supplied to the main scan line SM_1 via the second sub-scan line SS2_1 can be the same scan signal. Accordingly, the same scan signal can be supplied to the first pixel PX1 to the fifth pixel PX5 of the first pixel row PXR1 via the main scan line SM_1.

[0083] The first pixel PX1 to the fifth pixel PX5 can be connected to the first data line D1, the j-th data line Dj, the k-th data line Dk, the l-th data line Dl, and the m-th data line Dm, respectively. If a scan signal is supplied to the first scan line S1, data signals can be written to the first pixel PX1 to the fifth pixel PX5 through the first data line Dl, the j-th data line Dj, the k-th data line Dk, the l-th data line Dl, and the m-th data line Dm, respectively.

[0084] The scan signal can be transmitted to the main scan line SM_1 via the first sub-scan line SS1_1, and can be supplied from the first contact point CP1 corresponding to the first position P1 along both directions of the main scan line SM_1. For example, the scan signal can be supplied from the first contact point CP1 along the first direction DR1 and the opposite direction of the first direction DR1 via the main scan line SM_1. Similarly, the scan signal transmitted via the second sub-scan line SS2_1 can be supplied from the second contact point CP2 along both directions of the main scan line SM_1.

[0085] At this time, the load of the scan signal on the main scan line SM_1 and the pixels PX1 to PX5 connected to the main scan line SM_1 can increase as it moves away from the first contact point CP1. For example, the load of the scan signal can be greater at the second position P2 than at the first position P1 corresponding to the first contact point CP1, and the load of the scan signal can be greater at the third position P3 than at the second position P2. Furthermore, the load of the scan signal can increase as it moves away from the second contact point CP2. For example, the load of the scan signal can be greater at the fifth position P5 than at the second contact point CP2. In addition, since two contact points (the first contact point CP1 and the second contact point CP2) are formed in the first pixel row PXR1, the load at the fifth position P5, which corresponds to the midpoint between the first contact point CP1 and the second contact point CP2, can be the largest.

[0086] In other words, the waveform of the scan signal supplied to the first pixel PX1 corresponding to the third position P3 is affected by the load to a greater extent than the waveform of the scan signal supplied to the second pixel PX2 corresponding to the second position P2 near the first contact point CP1 (or the first position P1). For example, the scan signal supplied to the first pixel PX1 may be delayed by a degree corresponding to the relative distance between the second position P2 and the third position P3, compared to the scan signal supplied to the second pixel PX2.

[0087] Similarly, the waveform of the scan signal supplied to the fourth pixel PX4 corresponding to the fifth position P5 is more affected by the load than the waveform of the scan signals supplied to the third pixel PX3 and the fifth pixel PX5, which are close to the first contact point CP1 and the second contact point CP2.

[0088] That is, the load of the scanning signal can increase from the first contact point CP1 along the left direction (i.e., the opposite direction of the first direction DR1), and in the region between the first contact point CP1 and the second contact point CP2, the load of the scanning signal can increase as it approaches the fifth position P5 corresponding to the middle location.

[0089] Similarly, the i-th scan line Si may include a main scan line SM_i, a first sub-scan line SS1_i, and a second sub-scan line SS2_i. The scan signals supplied to the first sub-scan line SS1_i and the second sub-scan line SS2_i can be supplied to the sixth pixel PX6 to the tenth pixel PX10 of the i-th pixel row PXRi through the main scan line SM_i.

[0090] In the i-th pixel row PXRi, the load of the scan signal can increase from the first contact point CP1 along the left direction (i.e., the opposite direction of the first direction DR1), and the load of the scan signal can increase from the second contact point CP2 along the right direction (i.e., the first direction DR1). In the region between the first contact point CP1 and the second contact point CP2, the load of the scan signal can increase as it approaches the position corresponding to the middle location.

[0091] Furthermore, the nth scan line Sn may include a main scan line SM_n, a first sub-scan line SS1_n, and a second sub-scan line SS2_n. The scan signals supplied to the first sub-scan line SS1_n and the second sub-scan line SS2_n can be supplied to the eleventh pixel PX11 to the fifteenth pixel PX15 of the nth pixel row PXRn through the main scan line SM_n.

[0092] In the nth pixel row PXRn, the load of the scan signal can increase from the second contact point CP2 along the right direction (i.e., the first direction DR1). In the region between the first contact point CP1 and the second contact point CP2, the load of the scan signal can increase as it approaches the position corresponding to the middle location.

[0093] Furthermore, according to the reference Figure 2 The arrangement of the first contact point CP1 and the second contact point CP2 is explained because the lengths of the first sub-scan lines SS1_1 to SS1_n and the second sub-scan lines SS2_1 to SS2_n increase in the first direction DR1. Therefore, the load of the scan signal can gradually increase from the nth scan line Sn to the first scan line S1. That is, in the second direction DR2, from the scan drive unit ( Figure 1 The greater the distance from 200 to the corresponding pixel row, the greater the load on the scan signal can be.

[0094] For example, although the distance between the pixel corresponding to the position of the first contact point CP1 and the second contact point CP2 in each of the pixel rows PXR1 to PXRn is the same as that between the first contact point CP1 and the second contact point CP2 in the first direction DR1, due to the scanning drive unit (see...) Figure 1The load of the scan signal can vary depending on the distance from the scan drive unit 200 to the pixel rows PXR1 to PXRn. For example, the load of the scan signal supplied to the pixel corresponding to the position of the first contact point CP1 and the second contact point CP2 in the i-th pixel row PXR1 can be greater than the load of the scan signal supplied to the pixel corresponding to the position of the first contact point CP1 and the second contact point CP2 in the n-th pixel row PXRn. Similarly, the load of the scan signal supplied to the pixel corresponding to the position of the first contact point CP1 and the second contact point CP2 in the first pixel row PXR1 can be greater than the load of the scan signal supplied to the pixel corresponding to the position of the first contact point CP1 and the second contact point CP2 in the i-th pixel row PXR1.

[0095] The k-th pixel column PXCk can be connected to the k-th data line Dk. The data signal supplied to the k-th data line Dk can be supplied to the third pixel PX3, the eighth pixel PX8, and the thirteenth pixel PX13 of the k-th pixel column PXCk.

[0096] At this time, the load of the data signals on the k-th data line Dk and the pixels PX3, PX8, and PX13 connected to it can be increased further away in the second direction DR2. For example, the load of the data signals supplied to pixels PX3, PX8, and PX13 can be increased further away from the data drive unit in the second direction DR2. Figure 1 The data driving unit 300 is increased. As an example, the load of the data signal supplied to the eighth pixel PX8 can be greater than the load of the data signal supplied to the thirteenth pixel PX13, and the load of the data signal supplied to the third pixel PX3 can be greater than the load of the data signal supplied to the eighth pixel PX8.

[0097] To illustrate more specifically the load deviation of the scan signal and data signal based on the relative positions of pixels in the first direction DR1 and the second direction DR2, please refer to... Figures 4a to 5 .

[0098] Figures 4a to 4c It shows the supply to Figure 3 A graph illustrating the supply delay time of the scan signal for each pixel in a row. Figure 5 It shows the supply to Figure 3 A graph illustrating the supply delay time of the data signal for a pixel column.

[0099] Reference Figure 4a , Figure 4a The delay time (GDT) of the scan signal based on the relative position (POSITION) on the first direction (DR1) of the first pixel row (PXR1) is shown.

[0100] For reference Figure 3As explained, within the first pixel row PXR1, since the scan signal load is minimal at the first contact point CP1 and the second contact point CP2 corresponding to the first position P1, the first contact point CP1 and the second contact point CP2 can have the shortest scan signal delay time GDT(A). Furthermore, since the scan signal load increases as it moves away from the first contact point CP1 and the second contact point CP2 in the first direction DR1, the scan signal delay time GDT increases as it moves away from the first position P1 corresponding to the first contact point CP1, and the location farthest from the first position P1 can have the longest scan signal delay time GDT(A+E). Moreover, in the region between the first contact point CP1 and the second contact point CP2, the fifth position P5, corresponding to the midpoint between the first contact point CP1 and the second contact point CP2, can have the longest scan signal delay time GDT(A+D).

[0101] Reference Figure 4b , Figure 4b The delay time (GDT) of the scan signal based on the relative position (POSITION) on the first direction (DR1) of the i-th pixel row (PXRi) is shown.

[0102] With Figure 4a Similarly, within the i-th pixel row PXRi, the shortest scan signal delay time GDT(B) can be achieved at the first contact point CP1 and the second contact point CP2, and the scan signal delay time GDT can increase as the distance from the first contact point CP1 and the second contact point CP2 in the first direction DR1 increases. Furthermore, the region between the first contact point CP1 and the second contact point CP2 can have the longest scan signal delay time GDT(B+D) at the position corresponding to the midpoint between the first contact point CP1 and the second contact point CP2.

[0103] Reference Figure 4c , Figure 4c The delay time (GDT) of the scan signal based on the relative position (POSITION) on the first direction DR1 of the nth pixel row PXRn is shown.

[0104] With Figure 4aSimilarly, within the nth pixel row PXRn, the shortest scan signal delay time GDT(C) can be achieved at the first contact point CP1 and the second contact point CP2, and the scan signal delay time GDT can increase as it moves away from the first contact point CP1 and the second contact point CP2 in the first direction DR1. Within the nth pixel row PXRn, the longest scan signal delay time GDT(C+E') can be achieved at the position furthest from the first contact point CP1 and the second contact point CP2 in the first direction DR1 (e.g., the position corresponding to the fifteenth pixel PX15). Furthermore, in the region between the first contact point CP1 and the second contact point CP2, the longest scan signal delay time GDT(C+D) can be achieved at the position corresponding to the midpoint between the first contact point CP1 and the second contact point CP2.

[0105] Furthermore, as referenced Figure 1 and Figure 3 As explained, the greater the distance from the scan drive unit 200 to the pixel row in the second direction DR2, the greater the load on the scan signal can be. For example, if we compare the delay time GDT of the scan signal at the first contact point CP1 and the second contact point CP2 in each pixel row, the delay time A of the scan signal can be the longest at the first contact point CP1 and the second contact point CP2 of the first pixel row PXR1, which is the farthest from the scan drive unit 200 in the second direction DR2, and the delay time C of the scan signal can be the shortest at the first contact point CP1 and the second contact point CP2 of the nth pixel row PXRn, which is the shortest from the scan drive unit 200 in the second direction DR2. That is, A>B>C.

[0106] Reference Figure 5 , Figure 5 The delay time DDT of the data signal based on the relative position POSITION on the second direction DR2 of the k-th pixel column PXCk is shown.

[0107] For reference Figure 1 and Figure 3 As explained, within the k-th pixel column PXCk, since the data signal load increases with the distance from the data driving unit 300 in the second direction DR2, the position corresponding to the thirteenth pixel PX13 can have the shortest data signal delay time DDT(F), and the position corresponding to the third pixel PX3 can have the longest data signal delay time DDT(F+H). That is, F+H>F+G>F.

[0108] Figure 6 It is used to explain the basis Figure 2 A graph showing the relative positions of pixels within a pixel region, along with the load of the scan signal and the load of the data signal. Figures 7 to 9It is used to explain the provision to Figure 1 A diagram illustrating an example of a lookup table in the data-driven department.

[0109] Reference Figure 1 , Figure 3 as well as Figure 6 The control unit 400 can control the output timing of the data signal based on the scan signal and the load of the data signal according to the relative position of the pixels PX in the pixel unit 100.

[0110] In one embodiment, the control unit 400 can generate a timing control signal TCS for controlling the data signal output timing of the data drive unit 300 based on the load of the scan signal (hereinafter referred to as scan load) and the load of the data signal (hereinafter referred to as data load) according to the pre-stored relative positions within the pixel unit 100. For example, such as Figure 6 As shown, the scan load and data load from location A_P to location H_P can be pre-stored in the control unit 400.

[0111] Here, the data load is greatest at locations A_P, B_P, C_P, and D_P, and least at locations E_P, F_P, G_P, and H_P. That is, the data load is greatest at the location furthest from the data drive unit 300 on the second direction DR2, and least at the location closest to the data drive unit 300 on the second direction DR2.

[0112] Furthermore, at locations A_P, B_P, C_P, and D_P, the scan load is greatest at the distances from the scan drive unit 200 along the second direction DR2, while at locations E_P, F_P, G_P, and H_P, the scan load is smallest at the distances from the scan drive unit 200 along the second direction DR2.

[0113] Furthermore, the closer the scan is to the first contact point CPS1 or the second contact point CPS2, the smaller the scan load; conversely, the farther the scan is from the first contact point CPS1 or the second contact point CPS2, the larger the scan load. Also, in the region between the first contact point CPS1 and the second contact point CPS2, the closer the scan is to the intermediate location MPS, the larger the scan load can be. For example, at locations B_P, D_P, E_P, and G_P, the scan load corresponding to the distance from the first contact point CPS1 and the second contact point CPS2 along the first direction DR1 can be the smallest, while at locations A_P and H_P, the scan load corresponding to the distance from the first contact point CPS1 and the second contact point CPS2 along the first direction DR1 can be the largest. Furthermore, in the region between the first contact point CPS1 and the second contact point CPS2, at locations C_P and F_P, the scan load corresponding to the distance from the first contact point CPS1 and the second contact point CPS2 along the first direction DR1 can be the largest.

[0114] In this way, one of the following loads can be set for each location A_P, B_P, C_P, D_P, E_P, F_P, G_P, H_P: first load HHH, second load HMH, third load HLH, fourth load LHL, fifth load LML, and sixth load LLL. This can be done based on the scan load (or the sum of the scan load corresponding to the distance from the scan drive unit 200 on the second direction DR2 and the scan load corresponding to the distance from the first contact point CPS1 and the second contact point CPS2 on the first direction DR1) and the data load.

[0115] The first load HHH can represent the load when the scan load corresponding to the distance from the scan drive unit 200 in the second direction DR2, the scan load corresponding to the distance from the first contact point CPS1 and the second contact point CPS2 in the first direction DR1, and the data load are all at their maximum.

[0116] The second load HMH can represent the load at which the maximum scan load and data load are corresponding to the distance from the scan drive unit 200 on the second direction DR2, and the intermediate scan load corresponding to the distance from the first contact point CPS1 and the second contact point CPS2 on the first direction DR1.

[0117] The third load HLH can represent the load in the case where the scan load and data load are maximized according to the distance between the scan drive unit 200 on the second direction DR2, and the scan load is minimized according to the distance between the first contact point CPS1 and the second contact point CPS2 on the first direction DR1.

[0118] The fourth load LHL can represent the load when the scan load and data load are minimized corresponding to the distance from the scan drive unit 200 on the second direction DR2, and the scan load is maximized corresponding to the distance from the first contact point CPS1 and the second contact point CPS2 on the first direction DR1.

[0119] The fifth load LML can represent the load that is the minimum scan load and data load corresponding to the distance from the scan drive unit 200 on the second direction DR2, and the intermediate level of scan load corresponding to the distance from the first contact point CPS1 and the second contact point CPS2 on the first direction DR1.

[0120] The sixth load LLL can represent the load in the case where the scan load corresponding to the distance from the scan drive unit 200 in the second direction DR2, the scan load corresponding to the distance from the first contact point CPS1 and the second contact point CPS2 in the first direction DR1, and the data load are all minimized.

[0121] Here, the scan load (hereinafter referred to as the final scan load) can be determined as the sum of the scan load corresponding to the distance from the scan drive unit 200 in the second direction DR2 and the scan load corresponding to the distance from the first contact point CPS1 and the second contact point CPS2 in the first direction DR1.

[0122] At this point, the delay of the scan signal and the delay of the data signal supplied to the object pixel corresponding to the final scan load and data load can be different from each other, and thus the supply timing of the scan signal and the data signal can be consistent or inconsistent.

[0123] In one embodiment, when the timing of the supply of the scan signal and the data signal to the target pixel corresponding to the final scan load and the data load is consistent, the control unit 400 can control the data driving unit 300 to output the data signal without substantially delaying it.

[0124] In one embodiment, if the timing of the supply of the scan signal and the data signal to the target pixel corresponding to the final scan load and the data load is inconsistent, the control unit 400 may control the data driving unit 300 to delay the output of the data signal.

[0125] For example, when the data signal supply timing is later than the scan signal supply timing, the control unit 400 can control the data drive unit 300 to delay the data signal by a specific delay value, thereby ensuring that the data signal is output in accordance with the scan signal supply timing. As an example, the control unit 400 can delay the data signal output timing by a negative (-) delay value to advance the data signal supply timing.

[0126] As another example, when the data signal supply timing is earlier than the scan signal supply timing, the control unit 400 can control the data drive unit 300 to delay the data signal by a specific delay value, thereby ensuring that the data signal is output in accordance with the scan signal supply timing. For example, the control unit 400 can delay the data signal supply timing by delaying the data signal output timing by a positive (+) delay value.

[0127] Specifically, in Figure 6 Taking locations A_P to H_P shown within pixel unit 100 as examples, at locations E_P and G_P, the final scan load and data load can both be minimized (shown as LLL). In this case, the scan signal and data signal supplied to the pixel PX corresponding to locations E_P and G_P can be substantially undelayed. In other words, the supply timing of the scan signal and data signal supplied to the pixel PX corresponding to locations E_P and G_P can be consistent. For example, the supply to... Figure 3 The timing of the scan signal supply for the eleventh pixel PX11 and the thirteenth pixel PX13 can be consistent with the timing of the data signal supply. In this case, the control unit 400 can control the data drive unit 300 to output data signals without substantially delaying them.

[0128] Furthermore, although the data load is minimal at locations F_P and H_P, the scan load corresponding to the distances from the first contact point CPS1 and the second contact point CPS2 along the first direction DR1 can be an intermediate or maximum load (denoted as LML and LHL, respectively). In this case, the scan signal supplied to the pixel PX corresponding to locations F_P and H_P may be delayed depending on the final scan load. That is, at locations F_P and H_P, the timing of the scan signal and data signal supplied to the pixel PX may be inconsistent depending on the final scan load and data load. For example, the supply to… Figure 3 The supply timing of the scan signal and data signal for the twelfth pixel PX12 and the fifteenth pixel PX15 may be inconsistent. Specifically, the supply timing of the scan signal corresponds to the final scan load at location F_P and location H_P and is therefore delayed. Thus, the supply timing of the scan signal may be later than the supply timing of the data signal. In this case, the control unit 400 can control the data drive unit 300 to delay the data signal by a positive (+) delay value, thereby delaying the supply timing of the data signal and ensuring that the data signal is output in accordance with the supply timing of the scan signal.

[0129] Furthermore, at locations B_P and D_P, while the scan load corresponding to the distances from the first contact point CPS1 and the second contact point CPS2 in the first direction DR1 can be minimized, the scan load and data load corresponding to the distances from the scan drive unit 200 in the second direction DR2 can be maximized (shown as HLH). In this case, the scan signal and data signal supplied to the pixel PX corresponding to locations B_P and D_P can be delayed based on the final scan load and data load. Here, assuming that the supply timing of the data signal supplied to locations B_P and D_P is later than the supply timing of the scan signal based on the final scan load and data load, in this case, the control unit 400 can control the data drive unit 300 to delay the data signal by a negative (-) delay value and advance the supply timing of the data signal, thereby outputting the data signal in accordance with the supply timing of the scan signal. In contrast, assuming that the data signal supply timing to location B_P and location D_P is earlier than the scan signal supply timing based on the final scan load and data load, then in this case, the control unit 400 can control the data drive unit 300 to delay the data signal supply timing by a positive (+) delay value, thereby outputting the data signal supply timing in accordance with the scan signal supply timing. Such scan signal and data signal supply timing can vary depending on the design, such as the size and area of ​​the pixel unit 100.

[0130] Furthermore, at locations A_P and D_P, the control unit 400 can control the data drive unit 300 to make the supply timing of the data signal consistent with the supply timing of the scan signal, corresponding to the supply timing of the scan signal based on the final scan load and data load.

[0131] In one embodiment, the data driving unit 300 can adjust the output timing of the data signal based on a lookup table (LUT) included in the timing control signal (TCS) provided from the control unit 400. Here, the lookup table (LUT) can store delay values ​​of the data signal based on the relative positions of the pixels (PX) within the pixel unit 100. The delay value of the data signal can be determined based on the scan load and data load based on the relative positions of the pixels (PX), so that the supply timing of the scan signal and the supply timing of the data signal are consistent. The data driving unit 300 can adjust the output timing of the data signal based on this delay value.

[0132] For example, such as Figure 7 As shown, the lookup table (LUT) can store the delay values ​​t1 to t24 of the data signal at each position corresponding to each pixel PX of the pixel unit 100. Based on the lookup table (LUT) described above, the data driving unit 300 can control the output timing of the data signal at each position corresponding to each pixel PX.

[0133] In one embodiment, the control unit 400 can control the output timing of the data signal in units of pixel rows.

[0134] For example, the control unit 400 can set adjacent pixel rows (or adjacent main scan lines SM_1 to SM_n) in a pixel row as pixel row blocks BPXR, and control the output timing of the data signal output from one data line in units of pixel row blocks BPXR for each pixel column. In this case, such as Figure 8 As shown, the lookup table LUT' can store the delay values ​​t7 to t24 of the data signal in units of pixel row blocks BPXR for a single data line. For example, the control unit 400 can control the output timing of the data signal output from the first data line D1 in units of pixel row blocks BPXR for the first pixel column. In this case, the delay value t7 of the same data signal corresponding to the first data line D1 and the main scan lines SM_1 and SM_2 included in the same pixel row block BPXR can be stored in the lookup table LUT'. Similarly, for each of the pixel columns, the control unit 400 can control the output timing of the data signals output from each of the second data line D2, the j-th data line Dj, the k-th data line Dk, the l-th data line Dl, and the m-th data line Dm in units of pixel row blocks BPXR. In this case, the delay values ​​t8, t9, t10, t11, and t12 of the same data signals corresponding to the second data line D2, the j-th data line Dj, the k-th data line Dk, the l-th data line Dl, and the m-th data line Dm, as well as the main scan lines SM_1 and SM_2 included in the same pixel row block BPXR, can be stored in lookup table LUT' respectively.

[0135] In addition, although Figure 8 The illustration shows a scenario where two adjacent pixel rows in a pixel row are set as a pixel row block BPXR, but this is only an example; three or more adjacent pixel rows in a pixel row can also be set as a pixel row block BPXR.

[0136] In one embodiment, the control unit 400 can control the output timing of the data signal in units of pixel columns.

[0137] For example, the control unit 400 can set adjacent pixel columns (or adjacent data lines D1 to Dm) in a pixel column as pixel column blocks BPXC, and can control the output timing of the data signals output to the data lines in units of pixel column blocks BPXC. In this case, such as Figure 9As shown, the lookup table "LUT" can store the delay values ​​t2 to t6, t8 to t12, t14 to t18, and t20 to t24 of the data signal in units of pixel column blocks BPXC. For example, the control unit 400 can control the output timing of the data signal output to the first data line D1 and the second data line D2 in units of pixel column blocks BPXC for the first pixel row corresponding to the main scan line SM_1. In this case, the delay value t2 of the same data signal corresponding to the first pixel row (or the main scan line SM_1) and the first data line D1 and the second data line D2 included in the same pixel column block BPXC can be stored in the lookup table "LUT". Similarly, for each pixel row, the control unit 400 can control the output timing of the data signals output to the first data line D1 and the second data line D2 in units of pixel column blocks BPXC, corresponding to each of the main scan lines SM_2, SM_i, and SMn. In this case, the delay values ​​t8, t14, and t20 of the same data signals corresponding to the main scan lines SM_2, SM_i, and SMn, as well as the first data line D1 and the second data line D2 corresponding to the same pixel column block BPXC, are stored in the lookup table LUT".

[0138] In addition, although Figure 9 The illustration shows a scenario where two adjacent pixel columns in a pixel column are set as a pixel column block BPXC, but this is only an example. Three or more adjacent pixel columns in a pixel column can also be set as a pixel column block BPXC.

[0139] In this way, the control unit 400 and the data driving unit 300 can control the output timing of the data signals output to the data lines in units of pixel row blocks BPXR and / or pixel column blocks BPXC, thereby reducing the driving burden and power consumption of the control unit 400 and the data driving unit 300.

[0140] As described above, the display device 1000 according to an embodiment of the present invention can take into account the scanning load and data load of the single-sided driving mode, and control the output timing (output delay time) of the data signal differently according to the position of the pixel in the pixel section 100. Therefore, the charging rate deviation of the pixel data signal can be reduced, thereby improving the display quality.

[0141] Figure 10 and Figure 11 This is a diagram illustrating the operation of the control unit and data drive unit to explain the timing sequence of the output control data signals. Figure 10 and Figure 11 An example of data packets DATA#1 and DATA#2 transmitted from the control unit to the data drive unit is shown.

[0142] Furthermore, data packets DATA#1 and DATA#2 can be data packets transmitted to the data driver unit corresponding to a pixel column (or a data line), or as referred to Figure 9 The data packets described here may correspond to data lines included in the same pixel column block BPXC and are transmitted to the data driving unit. Hereinafter, the description is based on the case where data packets DATA#1 and DATA#2 are transmitted to the data driving unit corresponding to one pixel column (or one data line). That is, the description is based on the case where the control unit 400 controls the output timing of the data signals on a pixel column basis.

[0143] Furthermore, the following explanation will be based on the case where the control unit 400 controls the output timing of the data signal in units of pixel rows.

[0144] Reference Figures 1 to 3 , Figure 10 as well as Figure 11 Each of the data packets DATA#1 and DATA#2 may include a line start field SOL, a composition field Configuration, a pixel data field RGB Pixel Data, and a horizontal blanking field HBP.

[0145] The Line Start Field SOL can indicate the start of each line (each pixel row) of the image frame displayed in the pixel unit 100. The data driving unit 300 can operate an internal counter in response to the Line Start Field SOL, and distinguish between the Configuration field and the RGB Pixel Data field based on the counter's count result.

[0146] The Configuration field can include configuration data for controlling the data driving unit 300. This configuration data can include frame configuration data for controlling frame settings of image frames, or line configuration data for controlling the settings of each line. Furthermore, the configuration data can include a frame synchronization signal activated when transmitting image data for the last line of an image frame. The data driving unit 300 can identify the start of a vertical blank time period after receiving the current image data by receiving the activated frame synchronization signal. In addition, the configuration data can include various types of control data.

[0147] In one embodiment, the constitutive data may include references Figure 1 The timing control signal TCS is explained. The data drive unit 300 can control the output timing of the data signal by changing the length of the horizontal blank field HBP based on the timing control signal TCS included in the constitutive data.

[0148] The RGB Pixel Data field can include pixel data.

[0149] The horizontal blank field HBP can be an interval allocated to ensure that the data-driven section 300 drives the pixel section 100 based on the pixel data time.

[0150] As described above, when the supply timing of the scan signal and data signal is consistent based on the scan load and data load according to the relative positions of pixels PX within the pixel unit 100, the control unit 400 can control the data drive unit 300 to output data signals without substantially delaying them. For example, as Figure 10 As shown, the horizontal blank field HBP corresponding to each adjacent line LINE_1, LINE_2 (or each pixel row) can have a first length HT1. That is, the data driving unit 300 can read the data of the horizontal blank field HBP for each line LINE_1, LINE_2, corresponding to the first length HT1, based on the timing control signal TCS included in the configuration field Configuration.

[0151] In contrast, when the supply timing of the scan signal and data signal is inconsistent based on the scan load and data load according to the relative positions of pixels PX within the pixel unit 100, the control unit 400 can control the data drive unit 300 to delay the data signal by a specific delay value to make the supply timing of the data signal consistent with the supply timing of the scan signal. For example, such as Figure 11 As shown, the horizontal blank field HBP' corresponding to the first line LINE_1 can have a second length HT2 that is longer than the first length HT1 by the first delay length DT1, and the horizontal blank field HBP" corresponding to the second line LINE_2 can have a third length HT3 that is longer than the first length HT1 by the second delay length DT2. That is, the data driving unit 300 can read the data of the horizontal blank fields HBP' and HBP" for lines LINE_1 and LINE_2 corresponding to the second length HT2 and the third length HT3, respectively, based on the timing control signal TCS included in the configuration field Configuration.

[0152] In this case, the length of the horizontal blank field HBP' corresponding to the first line LINE_1 is changed, so the output timing of the data signal of the second line LINE_2, which is the next adjacent line, can be delayed by a first delay length DT1. Similarly, the length of the horizontal blank field HBP" corresponding to the second line LINE_2 is changed, so the output timing of the data signal of the next adjacent line can be delayed by a second delay length DT2.

[0153] In this way, the data driving unit 300 can change the length of the horizontal blank field (HBP) corresponding to the previous line (previous pixel row) of the corresponding line (current pixel row) and read it in accordance with the timing control signal TCS included in the configuration field of the data packet provided from the control unit 400, thereby controlling the output timing of the data signal corresponding to the adjacent corresponding line (current pixel row).

[0154] In addition, although Figure 11 The diagram illustrates a scenario where the length of the horizontal blank field is increased by delaying it by a positive (+) delay length (e.g., a first delay length DT1, a second delay length DT2). However, the length of the horizontal blank field can also be decreased by delaying it by a negative (-) delay length. In this case, the data signal can be delayed by a negative (-) delay value, allowing the data signal supply timing to be advanced.
