Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a display device and its driving method. Background Technology

[0002] Display resolution is one of the most important parameters affecting display quality. Traditional methods to improve display resolution primarily involve increasing the number of pixels per unit area by reducing the physical pixel size. However, as pixel size continues to shrink, manufacturing difficulties increase significantly, yield rates decrease, and manufacturing costs rise.

[0003] To improve display quality without significantly reducing physical pixel size, some existing technologies employ microlens arrays. These microlenses project sub-pixel images to different positions through optical magnification, creating a denser display dot matrix. Other technologies use prisms or optical shift layers, altering the light propagation path to make the displayed image appear to change position from the observer's perspective at different times. Still other technologies utilize multi-layered stacked emissive layers, placing emissive units in different layers and controlling the emissive timing of each layer to improve the equivalent resolution.

[0004] However, the aforementioned technical solutions offer only a limited improvement in display quality.

[0027] The display device of this application includes a display panel and a driving circuit. The display panel includes a plurality of sub-pixels arranged in an array. The driving circuit is configured to acquire target image data, generate a plurality of sub-frame image data in sequence according to the target image data, and drive the display panel to display the plurality of sub-frame images in sequence within a time period according to the plurality of sub-frame image data. The image data corresponding to the same target position of the target image data in different sub-frame image data are assigned to sub-pixel combinations located at different positions in the display panel, and the nominal centroids of the sub-pixel combinations in different sub-frame images do not coincide.

Since the sub-pixel combinations in different subframe images are located at different positions on the display panel, the nominal centroids of these sub-pixel combinations form multiple non-overlapping spatial points on the display panel. When the human eye observes multiple subframe images within a time period, due to the persistence of vision, the multiple subframe images are superimposed and fused in time to form a complete image. In this fused image, the luminous centroids corresponding to the image data at the same target location expand from a single centroid to multiple non-overlapping equivalent centroids. These equivalent centroids constitute a denser equivalent display dot matrix in the display panel than the physical sub-pixel array. The density of the equivalent display dot matrix is ​​higher than the density of the physical sub-pixel array; therefore, this application improves the equivalent resolution without increasing the number of physical sub-pixels.

[0029] In the technical solution of this application, the driving circuit sequentially drives the display panel to display multiple sub-frame images within one time cycle. The image data allocation method of the multiple sub-frame images ensures that the nominal centroids of the sub-pixel combinations in different sub-frames do not overlap. This driving method achieves an equivalent increase in centroid in the spatial dimension through multiplexing in the temporal dimension. Compared with the traditional method of improving resolution by reducing the physical pixel size, this application does not need to change the physical size of the sub-pixels, avoiding the problems of increased manufacturing difficulty, decreased yield, and increased manufacturing cost caused by pixel size reduction. Compared with technical solutions using microlens arrays, prisms, or optical shifting layers, this application does not need to set additional optical structures in the display panel, avoiding the problems of increased device thickness, difficult optical calibration, and increased cost. Compared with technical solutions using multi-layer stacked light-emitting layers, this application does not need to manufacture multi-layer light-emitting structures, reducing manufacturing complexity.

[0030] This application improves the equivalent resolution and enhances the clarity of the displayed image by allocating, processing, and timing the subframe image data through a driving circuit. Attached Figure Description

[0047] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0048] The terms “first,” “second,” and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms “multiple,” and similar words mean two or more, unless otherwise expressly specified.

[0049] The technical solutions of different embodiments of this application can be combined with each other.

[0050] The display devices provided in the embodiments of this application may be, for example, organic light-emitting diode (OLED) display devices, mini light-emitting diode (Mini-LED) display devices, or micro light-emitting diode (Micro-LED) display devices. The embodiments of this application are described using organic light-emitting diode display devices as an example.

[0051] Embodiments of this application provide a display device including a display panel and a driving circuit. The display panel includes a plurality of sub-pixels PX arranged in an array. The driving circuit is configured to acquire target image data, sequentially generate a plurality of sub-frame image data based on the target image data, and sequentially drive the display panel to display the plurality of sub-frame images based on the plurality of sub-frame image data within a time period. In different sub-frame image data, image data corresponding to the same target position in the target image data are assigned to sub-pixel combinations PG located at different positions in the display panel, and the nominal centroids NP of the sub-pixel combinations PG in different sub-frame images do not coincide.

[0052] In this context, the nominal centroid (NP) refers to the geometric center or weighted emission center position of the sub-pixel combination (PG). The equivalent centroid refers to the multiple non-overlapping emission center positions formed on the display panel by the temporal superposition of image data at the same target location within a time period, through the temporal superposition of multiple subframe images.

[0053] like Figure 1 As shown, the display panel DP is an organic light-emitting diode (OLED) display panel. The driving circuit includes a timing controller TCON and a source driver chip SDIC. The timing controller TCON receives target image data and generates multiple sub-frame image data. The source driver chip SDIC drives the sub-pixels PX of the display panel to emit light according to the sub-frame image data.

[0054] In this application, the driving circuit distributes image data corresponding to the same target location in the target image data to sub-pixel combinations PG located at different positions in different sub-frames, so that the pixel content of the same target location is displayed through multiple sub-pixel combinations PG with different spatial positions within a time period. Since the sub-pixel combinations PG in different sub-frame images are located at different positions on the display panel, the nominal centroids NP of these sub-pixel combinations PG form multiple non-overlapping spatial points on the display panel. When the human eye observes multiple sub-frame images within a time period, due to the persistence of vision, the multiple sub-frame images are superimposed and fused in time to form a complete image. In this fused image, the luminous centroid corresponding to the image data at the same target location expands from a single centroid to multiple non-overlapping equivalent centroids, which constitute a denser equivalent display dot matrix in the display panel than the physical sub-pixel array.

[0055] The driving circuit sequentially drives the display panel to display multiple sub-frame images within a time cycle. The image data allocation method corresponding to the multiple sub-frame images ensures that the nominal centroids (NP) of the sub-pixel combination (PG) do not overlap in different sub-frames. This driving method achieves an equivalent increase in centroids in the spatial dimension through multiplexing in the temporal dimension. Compared to the traditional method of improving resolution by reducing the physical pixel size, this application does not require changing the physical size of the sub-pixel (PX), avoiding the problems of increased manufacturing difficulty, decreased yield, and increased manufacturing cost caused by pixel size reduction. Compared to technical solutions using microlens arrays, prisms, or optical shifting layers, this application does not require additional optical components in the display panel, avoiding the problems of increased device thickness, difficult optical calibration, and increased cost. Compared to technical solutions using multi-layer stacked light-emitting layers, this application does not require the fabrication of multiple light-emitting layers, reducing manufacturing complexity.

[0056] The display panel includes a substrate, a gate driving circuit GOA disposed on the substrate, multiple gate lines GL, multiple light emission control signal lines EM, multiple data lines DL, multiple first power lines VDD, multiple second power lines VSS, multiple sub-pixels PX, and an encapsulation layer disposed on the sub-pixels PX. The gate driving circuit GOA is configured to output scan signals to the gate lines GL. The gate lines GL extend along a second direction D2, and the multiple gate lines GL are arranged along a first direction D1. The light emission control signal lines EM extend along the second direction D2, and the multiple light emission control signal lines EM are arranged along the first direction D1. The data lines DL extend along the first direction D1, and the multiple data lines DL are arranged along the second direction D2. The first power lines VDD and the second power lines VSS provide power supply voltages to the sub-pixels PX. Each sub-pixel PX includes a light-emitting element and a pixel driving circuit. The light-emitting element includes an anode, a light-emitting layer, and a cathode, with the light-emitting layer disposed between the anode and the cathode. The pixel driving circuit is configured to control the current flowing through the light-emitting element to control the brightness of the light-emitting element.

[0057] The driving circuit includes a timing controller (TCON) and multiple source driver chips (SDICs). The timing controller (TCON) is configured to receive target image data and generate control signals and subframe image data. The source driver chips (SDICs) are configured to generate data signals based on the subframe image data and output these data signals to the data line (DL). The timing controller (TCON) outputs a gate control signal to the gate driver circuit (GOA), which in turn outputs scan signals sequentially to the gate line (GL) based on the gate control signal. The timing controller (TCON) outputs source control signals and subframe image data to the source driver chips (SDICs), which in turn output data signals to the data line (DL) based on the source control signals and subframe image data.

[0058] The present application will now be described in conjunction with specific embodiments.

[0059] Example 1 like Figure 2 As shown, an embodiment of this application provides a display device, which includes a display panel and a driving circuit.

[0060] The display panel includes multiple sub-pixels PX arranged in an array. Each sub-pixel PX includes multiple first-color sub-pixels, multiple second-color sub-pixels, and multiple third-color sub-pixels. The first-color sub-pixels are red sub-pixels R, the second-color sub-pixels are blue sub-pixels B, and the third-color sub-pixels are green sub-pixels G. The sub-pixel PX is rectangular in shape.

[0061] Multiple sub-pixels PX are arranged in a matrix, forming multiple rows of sub-pixels. Each row of sub-pixels includes multiple first-color sub-pixels, multiple second-color sub-pixels, and multiple third-color sub-pixels. The multiple rows of sub-pixels include a first row of sub-pixels, a second row of sub-pixels, and a third row of sub-pixels arranged along a first direction D1. The first direction D1 is the vertical direction.

[0062] In the first row of sub-pixels, the first color sub-pixels, the third color sub-pixels, and the second color sub-pixels are arranged periodically along the second direction D2 in the order of first color sub-pixels, third color sub-pixels, and second color sub-pixels. In the second row of sub-pixels, the second color sub-pixels, the first color sub-pixels, and the third color sub-pixels are arranged in a repeating sequence along the second direction D2. In the third row of sub-pixels, the third color sub-pixels, the second color sub-pixels, and the first color sub-pixels are arranged in a repeating sequence along the second direction D2. The second row of sub-pixels is offset by one sub-pixel PX relative to the first row of sub-pixels in the second direction D2, and the second row of sub-pixels is adjacent to the first row of sub-pixels along the first direction D1. The third row of sub-pixels is offset by one sub-pixel PX relative to the second row of sub-pixels in the second direction D2, and the third row of sub-pixels is adjacent to the second row of sub-pixels along the first direction D1. The second direction D2 is a horizontal direction and is perpendicular to the first direction D1. Multiple sub-pixels PX include a fourth row of sub-pixels, which is arranged in the same way as the first row of sub-pixels, and the fourth row of sub-pixels is adjacent to the third row of sub-pixels along the first direction D1. The arrangement of sub-pixels in the fourth row and thereafter repeats the arrangement pattern of sub-pixels from the first row to the third row.

[0063] Multiple sub-pixels PX are further arranged into multiple columns of sub-pixels, including a first column, a second column, and a third column of sub-pixels arranged along the second direction D2. In the first column, the first-color sub-pixel, the second-color sub-pixel, and the third-color sub-pixel are arranged in a repeating pattern along the first direction D1. In the second column, the third-color sub-pixel, the first-color sub-pixel, and the second-color sub-pixel are arranged in a repeating pattern along the first direction D1. In the third column, the second-color sub-pixel, the third-color sub-pixel, and the first-color sub-pixel are arranged in a repeating pattern along the first direction D1. The arrangement of the fourth column and subsequent sub-pixels PX repeats the arrangement pattern from the first to the third column of sub-pixels.

[0064] In two adjacent rows of sub-pixels, the sub-pixels in the latter row are offset relative to the sub-pixels in the former row in the second direction D2 by the width of one sub-pixel PX, so that sub-pixels PX of the same color are not in the same horizontal coordinate position between adjacent rows of sub-pixels.

[0065] The driving circuit is configured to acquire target image data, sequentially generate multiple sub-frame image data based on the target image data, and sequentially drive the display panel to display multiple sub-frame images within a time period based on the multiple sub-frame image data. In different sub-frame image data, image data corresponding to the same target position in the target image data are assigned to sub-pixel combinations PG located at different positions in the display panel, and the nominal centroids NP of the sub-pixel combinations PG in different sub-frame images do not coincide.

[0066] The multiple subframe images include at least three subframe images. A subpixel combination PG includes three adjacent subpixels PX along a first direction D1, or a subpixel combination PG includes three adjacent subpixels PX along a second direction D2. The driving circuit is configured to offset the subpixel combination PG along the first direction D1, along the second direction D2, or along both directions D1 and D2 in different subframe images.

[0067] The driving circuit is configured to decompose the image data at each target location in the target image data into a first color component, a second color component, and a third color component. In each subframe image data, the driving circuit allocates the first color component, the second color component, and the third color component according to the positions of the first color subpixel, the second color subpixel, and the third color subpixel in the subpixel combination PG.

[0068] like Figure 3 As shown, the driving circuit is configured to sequentially output three subframe images in a horizontal one-dimensional multiplexing mode. In the first subframe image, image data corresponding to the same target position of the target image data is allocated to a subpixel combination PG located at the first position. This subpixel combination PG includes a first color subpixel R[i,j], a third color subpixel G[i+1,j], and a second color subpixel B[i+2,j] located in the same row and adjacent to each other, forming a first horizontal offset state. In the second subframe image, image data corresponding to the same target position is allocated to a subpixel combination PG located at the second position. This subpixel combination PG is shifted relative to the first position in the second direction D2 by the width of one subpixel PX, and includes the third color subpixel G[i+1,j], the second color subpixel B[i+2,j], and the first color subpixel R[i+3,j], forming a second horizontal offset state. In the third subframe image, the image data corresponding to the same target position is assigned to the subpixel combination PG located at the third position. The subpixel combination PG is shifted relative to the second position in the second direction D2 by the width of one subpixel PX, including the second color subpixel B[i+2,j], the first color subpixel R[i+3,j] and the third color subpixel G[i+4,j], forming a third lateral offset state.

[0069] The nominal centroids NP of the sub-pixel combination PG corresponding to the three lateral offset states do not coincide. When the driving circuit continues to shift the sub-pixel combination PG by the width of one sub-pixel PX in the second direction D2, the new sub-pixel combination PG includes the first color sub-pixel R[i+3,j], the third color sub-pixel G[i+4,j], and the second color sub-pixel B[i+5,j]. The nominal centroid NP of this new sub-pixel combination PG coincides with the nominal centroid of the adjacent target position in the first lateral offset state, and therefore is not counted as a new effective offset state.

[0070] The driving circuit is also configured to sequentially output three subframe images in a vertical one-dimensional multiplexing mode. In the first subframe image, image data corresponding to the same target position of the target image data is allocated to a subpixel combination PG located at a first position. This subpixel combination PG includes a first color subpixel R[i,j], a second color subpixel B[i,j+1], and a third color subpixel G[i,j+2] located in the same column and adjacent to each other, forming a first vertical offset state. In the second subframe image, image data corresponding to the same target position is allocated to a subpixel combination PG located at a second position. This subpixel combination PG is shifted relative to the first position in a first direction D1 by the height of one subpixel PX, and includes the second color subpixel B[i,j+1], the third color subpixel G[i,j+2], and the first color subpixel R[i,j+3], forming a second vertical offset state. In the third subframe image, the image data corresponding to the same target position is assigned to the sub-pixel combination PG located at the third position. The sub-pixel combination PG is shifted relative to the second position in the first direction D1 by the height of one sub-pixel PX, including the third color sub-pixel G[i,j+2], the first color sub-pixel R[i,j+3] and the second color sub-pixel B[i,j+4], forming a third vertical offset state.

[0071] The nominal centroids NP of the sub-pixel combination PG corresponding to the three longitudinal offset states do not coincide. When the driving circuit continues to shift the sub-pixel combination PG by the height of one sub-pixel PX in the first direction D1, the nominal centroid of the new sub-pixel combination PG coincides with the nominal centroid NP of the adjacent target position in the first longitudinal offset state, and therefore is not counted as a new effective offset state.

[0072] The driving circuit is configured to distribute image data corresponding to the same target position to sub-pixel combinations PG located at nine different positions in nine sub-frame images, and sequentially drive the display panel to display the nine sub-frame images within a time period. The nine different positions are arranged in three rows and three columns in the display panel.

[0073] The nine subframes correspond to nine combined offset states, namely (0,0), (1,0), (2,0), (0,1), (1,1), (2,1), (0,2), (1,2), and (2,2). The combined offset state (0,0) corresponds to the base offset state. The combined offset state (1,0) represents an offset of one sub-pixel PX in the second direction D2; the combined offset state (2,0) represents an offset of two sub-pixels PX in the second direction D2; the combined offset state (0,1) represents an offset of one sub-pixel PX in the first direction D1; the combined offset state (1,1) represents an offset of one sub-pixel PX in the first direction D1 and an offset of one sub-pixel PX in the second direction D2; and the combined offset state (2,1) represents an offset of... The first offset state (0, 2) represents the width of two sub-pixels PX offset in the second direction D2 and the height of one sub-pixel PX offset in the first direction D1. The second offset state (1, 2) represents the width of one sub-pixel PX offset in the second direction D2 and the height of two sub-pixels PX offset in the first direction D1. The third offset state (2, 2) represents the width of two sub-pixels PX offset in the first direction D1 and the height of two sub-pixels PX offset in the second direction D2.

[0074] like Figure 4 As shown, in the initial state, the nominal centroid NP of the image data corresponding to the same target location in the target image data is a spatial point. In the two-dimensional multiplexing mode, the driving circuit sequentially outputs nine sub-frame images, and the image data of the same target location forms nine non-coincident equivalent centroids arranged in three rows and three columns in the nine sub-frame images.

[0075] Within one time period, the driving circuit sequentially drives the display panel to display nine sub-frame images. The duration of the time period is less than or equal to the visual persistence time of the human eye. Multiple sub-frame images observed by the human eye within one time period are superimposed and fused in time to form a complete image. When displaying the first sub-frame image, the source driver chip SDIC generates a data signal based on the first sub-frame image data and outputs the data signal to the corresponding data line DL to drive the first color sub-pixel R[i,j], the third color sub-pixel G[i+1,j], and the second color sub-pixel B[i+2,j] at the corresponding positions to emit light. When displaying the second sub-frame image, the source driver chip SDIC generates a data signal based on the second sub-frame image data and outputs the data signal to the corresponding data line DL to drive the third color sub-pixel G[i+1,j], the second color sub-pixel B[i+2,j], and the first color sub-pixel R[i+3,j] at the corresponding positions to emit light. When displaying subsequent sub-frame images, the driving circuit sequentially drives the sub-pixel combination PG at the corresponding positions to emit light.

[0076] Since the first color sub-pixel, the third color sub-pixel, and the second color sub-pixel in the first row are arranged repeatedly along the second direction D2, the second color sub-pixel, the first color sub-pixel, and the third color sub-pixel in the second row are arranged repeatedly along the second direction D2, and the third color sub-pixel, the second color sub-pixel, and the first color sub-pixel in the third row are arranged repeatedly along the second direction D2, when the sub-pixel combination PG is translated sequentially along the second direction D2, the color combination covered by the sub-pixel combination PG is RGB, GBR, and BRG in sequence. The nominal centroids NP of the three color combinations do not coincide with each other, forming three effective lateral offset states. In the first column of sub-pixels, the first, second, and third color sub-pixels are arranged sequentially along the first direction D1. In the second column of sub-pixels, the third, first, and second color sub-pixels are arranged sequentially along the first direction D1. In the third column of sub-pixels, the second, third, and first color sub-pixels are arranged sequentially along the first direction D1. When the sub-pixel combination PG is sequentially translated along the first direction D1, the color combinations covered by the sub-pixel combination PG are RBG, BGR, and GRB, respectively. The nominal centroids NP of the three color combinations do not coincide, forming three effective vertical offset states. The three effective horizontal offset states are combined with the three effective vertical offset states in pairs to form nine combined offset states, thus forming nine non-coincident equivalent centroids within one time period.

[0077] Embodiments of this application also provide a driving method for a display device, the display device including a display panel, the display panel including a plurality of sub-pixels PX arranged in an array. The plurality of sub-pixels PX includes a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The plurality of sub-pixels PX includes a first row of sub-pixels arranged along a second direction D2, in which the first color sub-pixel, the third color sub-pixel, and the second color sub-pixel are arranged in a repeating pattern along the second direction D2. The plurality of sub-pixels PX includes a second row of sub-pixels arranged along the second direction D2, the second row of sub-pixels being offset relative to the first row of sub-pixels in the second direction D2 by the width of one sub-pixel PX, and the second row of sub-pixels being adjacent to the first row of sub-pixels along a first direction D1.

[0078] The driving method includes: Acquire target image data; At least three sub-frame image data are generated sequentially within a time period based on the target image data. The sub-pixel combinations PG corresponding to the at least three sub-frame image data are shifted sequentially along a first direction D1, or sequentially along a second direction D2. In different sub-frame image data, image data corresponding to the same target position in the target image data are assigned to sub-pixel combinations PG located at different positions on the display panel. The nominal centroid NP of the sub-pixel combinations PG in different sub-frame images does not coincide. The display panel is driven to display multiple subframe images sequentially based on the image data of multiple subframes.

[0079] In one implementation, generating multiple subframe image data sequentially within a time period based on the target image data includes: generating nine subframe image data sequentially within a time period based on the target image data, wherein the image data corresponding to the same target position in the target image data in the nine subframe image data are respectively assigned to subpixel combinations PG located at nine different positions, and the nine different positions are arranged in three rows and three columns on the display panel.

[0080] Example 2 like Figure 5 As shown, Embodiment 2 of this application provides a display device, which includes a display panel and a driving circuit.

[0081] The display panel includes multiple sub-pixels PX arranged in an array. Each sub-pixel PX includes a first color sub-pixel, a second color sub-pixel, a third color sub-pixel, and a fourth color sub-pixel. The first color sub-pixel is a red sub-pixel R, the second color sub-pixel is a blue sub-pixel B, the third color sub-pixel is a first-band green sub-pixel G1, and the fourth color sub-pixel is a second-band green sub-pixel G2. The third color sub-pixel G1 and the fourth color sub-pixel G2 have different emission peak wavelengths. The sub-pixels PX are hexagonal in shape, and the multiple sub-pixels PX are arranged in a honeycomb pattern.

[0082] Multiple sub-pixels PX are arranged in alternating first and second type pixel columns. The first type pixel column includes first-color sub-pixels and second-color sub-pixels arranged alternately along a first direction D1. The second type pixel column includes third-color sub-pixels and fourth-color sub-pixels arranged alternately along the first direction D1. The first direction D1 is the vertical direction. Adjacent pixel columns are staggered relative to each other in the first direction D1 by a first preset distance, which is half the height of a sub-pixel PX.

[0083] The first and second pixel columns are arranged alternately along the second direction D2. The second direction D2 is a horizontal direction and is perpendicular to the first direction D1. In the first pixel column, the first and second color sub-pixels are arranged alternately along the first direction D1. In the second pixel column, the third and fourth color sub-pixels are arranged alternately along the first direction D1. Adjacent first and second pixel columns are offset by half a sub-pixel PX in the first direction D1, such that any first or second color sub-pixel in the first pixel column is adjacent to a third and a fourth color sub-pixel on its left and right sides.

[0084] The driving circuit is configured to acquire target image data, sequentially generate multiple sub-frame image data based on the target image data, and sequentially drive the display panel to display multiple sub-frame images within a time period based on the multiple sub-frame image data. In different sub-frame image data, image data corresponding to the same target position in the target image data are assigned to sub-pixel combinations PG located at different positions in the display panel, and the nominal centroids NP of the sub-pixel combinations PG in different sub-frame images do not coincide.

[0085] The subpixel group PG includes adjacent first color subpixels, second color subpixels, third color subpixels, and fourth color subpixels. The driving circuit is configured to distribute image data corresponding to the same target position to the subpixel group PG located at four different positions in the four subframe images, and sequentially drive the display panel to display the four subframe images within a time period. The four different positions are arranged in two rows and two columns in the display panel.

[0086] The driving circuit is configured to decompose the image data at each target location in the target image data into a first color component, a second color component, and a third color component. The driving circuit is configured to calculate the first sub-color component assigned to the third color sub-pixel and the second sub-color component assigned to the fourth color sub-pixel based on the third color component of the target image data and the chromaticity coordinates of the third and fourth color sub-pixels. For each target location in the target image data, the driving circuit calculates the first and second sub-color components based on the third color component of that target location and the chromaticity coordinates of the third and fourth color sub-pixels. In each subframe image data, the driving circuit assigns the first sub-color component to the third color sub-pixel and the second sub-color component to the fourth color sub-pixel.

[0087] When calculating the first and second sub-color components, the driving circuit first determines the chromaticity coordinates and brightness of the target green based on the third color component of the target image data. Then, based on the chromaticity coordinates of the third and fourth color sub-pixels and the target green, the driving circuit uses a chromaticity mixing algorithm to calculate the brightness values ​​that should be allocated to each of the third and fourth color sub-pixels. Furthermore, the driving circuit compensates for the brightness values ​​allocated to the third and fourth color sub-pixels based on their luminous efficiency to ensure that the color of the mixed light emitted by the third and fourth color sub-pixels matches the color of the target green.

[0088] In another implementation, the driving circuit uses the first, second, third, and fourth color sub-pixels to form a multi-primary-color correction matrix. Based on this matrix, the driving circuit converts the first, second, and third color components of the target image data into their respective driving values ​​for the first, second, third, and fourth color sub-pixels, thereby reducing color fringing, improving brightness efficiency, or expanding the color gamut.

[0089] like Figure 6As shown, in the first subframe image, image data corresponding to the same target position in the target image data is assigned to a subpixel combination PG located at the first position. This subpixel combination PG includes a first color subpixel R[i,j], a second color subpixel B[i,j+1], a third color subpixel G1[i+1,j], and a fourth color subpixel G2[i+1,j+1], forming a reference offset state. In the second subframe image, image data corresponding to the same target position is assigned to a subpixel combination PG located at the second position. This subpixel combination PG is shifted by a preset horizontal distance relative to the first position in the second direction D2, including the third color subpixel G1[i+1,j], the fourth color subpixel G2[i+1,j+1], the first color subpixel R[i+2,j], and the second color subpixel B[i+2,j+1], forming a horizontal offset state. In the third subframe image, image data corresponding to the same target position is assigned to a subpixel combination PG located at the third position. This subpixel combination PG is shifted relative to the first position along the first direction D1 by a preset vertical distance, including the second color subpixel B[i, j+1], the first color subpixel R[i, j+2], the fourth color subpixel G2[i+1, j+1], and the third color subpixel G1[i+1, j+2], forming a vertical offset state. In the fourth subframe image, image data corresponding to the same target position is assigned to a subpixel combination PG located at the fourth position. This subpixel combination PG is shifted relative to the first position along the second direction D2 by a preset horizontal distance and along the first direction D1 by a preset vertical distance, including the fourth color subpixel G2[i+1, j+1], the third color subpixel G1[i+1, j+2], the second color subpixel B[i+2, j+1], and the first color subpixel R[i+2, j+2], forming a combined horizontal and vertical offset state.

[0090] The offsets for the four offset states are (0, 0), (p_x, 0), (0, p_y), and (p_x, p_y), where p_x is the preset horizontal spacing and p_y is the preset vertical spacing. The nominal centroid NP of the sub-pixel combination PG corresponding to the four offset states does not coincide.

[0091] like Figure 7 As shown, in the initial state, the nominal centroid NP of the image data corresponding to the same target location in the target image data is a spatial point. In the quadruple offset state multiplexing mode, the driving circuit outputs four sub-frame images in sequence, and the image data of the same target location forms four non-coincident equivalent centroids arranged in two rows and two columns in the four sub-frame images.

[0092] Within one time cycle, the driving circuit sequentially drives the display panel to display four sub-frame images. When displaying the first sub-frame image, the driving circuit drives the first color sub-pixel R[i,j], the second color sub-pixel B[i,j+1], the third color sub-pixel G1[i+1,j], and the fourth color sub-pixel G2[i+1,j+1] to emit light. When displaying the second sub-frame image, the driving circuit drives the third color sub-pixel G1[i+1,j], the fourth color sub-pixel G2[i+1,j+1], the first color sub-pixel R[i+2,j], and the second color sub-pixel B[i+2,j+1] to emit light. When displaying the third sub-frame image, the driving circuit drives the second color sub-pixel B[i,j+1], the first color sub-pixel R[i,j+2], the fourth color sub-pixel G2[i+1,j+1], and the third color sub-pixel G1[i+1,j+2] to emit light. When displaying the fourth subframe image, the driving circuit drives the fourth color sub-pixel G2[i+1, j+1], the third color sub-pixel G1[i+1, j+2], the second color sub-pixel B[i+2, j+1], and the first color sub-pixel R[i+2, j+2] to emit light.

[0093] Since the first type of pixel column includes first-color sub-pixels and second-color sub-pixels arranged alternately along the first direction D1, and the second type of pixel column includes third-color sub-pixels and fourth-color sub-pixels arranged alternately along the first direction D1, adjacent pixel columns are offset relative to each other by half the height of a sub-pixel PX in the first direction D1, such that any first-color sub-pixel or second-color sub-pixel is surrounded by third-color sub-pixels and fourth-color sub-pixels. When the driving circuit causes the sub-pixel combination PG to shift sequentially in the first direction D1 and the second direction D2, the sub-pixel combination PG always includes first-color sub-pixels, second-color sub-pixels, third-color sub-pixels, and fourth-color sub-pixels, and the nominal centroid NP of the sub-pixel combination PG corresponding to the four shift states does not coincide with each other, forming four non-coincident equivalent centroids.

[0094] Embodiments of this application also provide a driving method for a display device, the display device including a display panel, the display panel including a plurality of sub-pixels PX arranged in an array. The plurality of sub-pixels PX includes a first color sub-pixel, a second color sub-pixel, a third color sub-pixel, and a fourth color sub-pixel, wherein the emission peak wavelengths of the third color sub-pixel and the fourth color sub-pixel are different. The plurality of sub-pixels PX are arranged in alternating first type pixel columns and second type pixel columns. The first type pixel column includes first color sub-pixels and second color sub-pixels arranged alternately along a first direction D1. The second type pixel column includes third color sub-pixels and fourth color sub-pixels arranged alternately along the first direction D1. Adjacent pixel columns are staggered relative to each other by a first preset distance in the first direction D1.

[0095] The driving method includes: Acquire target image data; Four sub-frame image data are generated sequentially within a time period based on the target image data. Image data corresponding to the same target location in the target image data are assigned to four different sub-pixel combinations PG located at different positions. Each sub-pixel combination PG contains a first-color sub-pixel, a second-color sub-pixel, a third-color sub-pixel, and a fourth-color sub-pixel. These four different positions are arranged in two rows and two columns on the display panel. In different sub-frame image data, image data corresponding to the same target location in the target image data are assigned to different sub-pixel combinations PG on the display panel. The nominal centroid NP of each sub-pixel combination PG in different sub-frame images does not coincide. The display panel is driven to display multiple subframe images sequentially based on the image data of multiple subframes.

[0096] Example 3 like Figure 8 As shown, Embodiment 3 of this application provides a display device, which includes a display panel and a driving circuit.

[0097] The display panel includes multiple sub-pixels PX arranged in an array. Each sub-pixel PX includes a first color sub-pixel, a second color sub-pixel, a third color sub-pixel, and a fourth color sub-pixel. The first color sub-pixel is a red sub-pixel R, the second color sub-pixel is a blue sub-pixel B, the third color sub-pixel is a first-band green sub-pixel G1, and the fourth color sub-pixel is a second-band green sub-pixel G2. The third color sub-pixel G1 and the fourth color sub-pixel G2 have different emission peak wavelengths. The shape of each sub-pixel PX is diamond-shaped.

[0098] Multiple sub-pixels PX are arranged in alternating columns of a first color pixel, a second type pixel, a second color pixel, and a second type pixel along a second direction D2. The first color pixel column includes first-color sub-pixels arranged along a first direction D1. The second color pixel column includes second-color sub-pixels arranged along a first direction D1. The second type pixel column includes third-color and fourth-color sub-pixels arranged alternately along a first direction D1. The first direction D1 is vertical, and the second direction D2 is horizontal, perpendicular to the first direction D1. Adjacent pixel columns are staggered relative to each other along the first direction D1 by a second preset distance, which is half the diagonal length of a rhombus-shaped sub-pixel PX.

[0099] The first and second color pixel columns are arranged alternately in the second direction D2. A second type of pixel column is placed between the first and second color pixel columns. The first color pixel column, the second type of pixel column, the second color pixel column, and the second type of pixel column are arranged in a repeating sequence in the second direction D2. Adjacent pixel columns are offset by half the diagonal length of a rhombus-shaped sub-pixel PX in the first direction D1, so that any first color sub-pixel or second color sub-pixel is surrounded by a third color sub-pixel and a fourth color sub-pixel.

[0100] The driving circuit is configured to acquire target image data, sequentially generate multiple sub-frame image data based on the target image data, and sequentially drive the display panel to display multiple sub-frame images within a time period based on the multiple sub-frame image data. In different sub-frame image data, image data corresponding to the same target position in the target image data are assigned to sub-pixel combinations PG located at different positions in the display panel, and the nominal centroids NP of the sub-pixel combinations PG in different sub-frame images do not coincide.

[0101] The subpixel group PG includes adjacent first color subpixels, second color subpixels, third color subpixels, and fourth color subpixels. The driving circuit is configured to distribute image data corresponding to the same target position to the subpixel group PG located at four different positions in the four subframe images, and sequentially drive the display panel to display the four subframe images within a time period. The four different positions are arranged in two rows and two columns in the display panel.

[0102] The driving circuit is configured to calculate a first sub-color component assigned to the third color sub-pixel and a second sub-color component assigned to the fourth color sub-pixel based on the third color component of the target image data and the chromaticity coordinates of the third and fourth color sub-pixels. For each target location in the target image data, the driving circuit calculates the first and second sub-color components based on the third color component of that target location and the chromaticity coordinates of the third and fourth color sub-pixels. In each subframe image data, the driving circuit assigns the first sub-color component to the third color sub-pixel and the second sub-color component to the fourth color sub-pixel.

[0103] like Figure 9 As shown, the driving circuit performs spatiotemporal multiplexing driving through four combined offset states. The four offset states are: the reference offset state, the lateral offset state offset by one sub-pixel distance along the second direction D2, the longitudinal offset state offset by one sub-pixel distance along the first direction D1, and the combined offset state offset by one sub-pixel distance along both the second direction D2 and the first direction D1. The sub-pixel distance is the length of the diagonal of the rhombus.

[0104] In the first subframe image, image data corresponding to the same target location in the target image data is assigned to a subpixel combination PG located at the first position. This subpixel combination PG includes four adjacent diamond-shaped subpixels PX. These four subpixels PX include at least a first color subpixel R[i,j], a third color subpixel G1[i+1,j], a fourth color subpixel G2[i+1,j+1], and a second color subpixel B[i+2,j], forming a baseline offset state. In the second subframe image, this subpixel combination PG is shifted one subpixel distance along the second direction D2, covering the new first color subpixel, second color subpixel, third color subpixel, and fourth color subpixel, including the second color subpixel B[i+2,j], the third color subpixel G1[i+3,j], the fourth color subpixel G2[i+3,j+1], and the first color subpixel R[i+4,j], forming a lateral offset state. In the third subframe image, the subpixel combination PG is shifted by one subpixel distance along the first direction D1, covering another new first color subpixel, second color subpixel, third color subpixel, and fourth color subpixel, including first color subpixel R[i, j+1], fourth color subpixel G2[i+1, j+1], third color subpixel G1[i+1, j+2], and second color subpixel B[i+2, j+1], forming a vertical offset state. In the fourth subframe image, the subpixel combination PG is shifted by one subpixel distance along both the second direction D2 and the first direction D1, respectively, covering a fourth group of first color subpixels, second color subpixels, third color subpixels, and fourth color subpixels, including second color subpixel B[i+2, j+1], fourth color subpixel G2[i+3, j+1], third color subpixel G1[i+3, j+2], and first color subpixel R[i+4, j+1], forming a horizontal and vertical combination offset state.

[0105] like Figure 10 As shown, in the initial state, the nominal centroid NP of the image data corresponding to the same target location in the target image data is a spatial point. In the quadruple offset state multiplexing mode, the driving circuit outputs four sub-frame images in sequence, and the image data of the same target location forms four non-coincident equivalent centroids arranged in two rows and two columns in the four sub-frame images.

[0106] Within one time cycle, the driving circuit sequentially drives the display panel to display four sub-frame images. When displaying the first sub-frame image, the driving circuit drives the first color sub-pixel R[i,j], the third color sub-pixel G1[i+1,j], the fourth color sub-pixel G2[i+1,j+1], and the second color sub-pixel B[i+2,j] to emit light. When displaying the second sub-frame image, the driving circuit drives the second color sub-pixel B[i+2,j], the third color sub-pixel G1[i+3,j], the fourth color sub-pixel G2[i+3,j+1], and the first color sub-pixel R[i+4,j] to emit light. When displaying the third sub-frame image, the driving circuit drives the first color sub-pixel R[i,j+1], the fourth color sub-pixel G2[i+1,j+1], the third color sub-pixel G1[i+1,j+2], and the second color sub-pixel B[i+2,j+1] to emit light. When displaying the fourth subframe image, the driving circuit drives the second color sub-pixel B[i+2, j+1], the fourth color sub-pixel G2[i+3, j+1], the third color sub-pixel G1[i+3, j+2], and the first color sub-pixel R[i+4, j+1] to emit light.

[0107] Since the first color pixel column includes first color sub-pixels arranged along the first direction D1, the second color pixel column includes second color sub-pixels arranged along the first direction D1, and the second type of pixel column includes third and fourth color sub-pixels alternately arranged along the first direction D1, the first color pixel column, the second type of pixel column, the second color pixel column, and the second type of pixel column are alternately arranged in the second direction D2. Adjacent pixel columns are offset relative to each other in the first direction D1 by half the diagonal length of the rhombus sub-pixel PX, so that any first color sub-pixel or second color sub-pixel is surrounded by third and fourth color sub-pixels. When the driving circuit causes the sub-pixel combination PG to shift sequentially along the diagonal direction of the rhombus, the sub-pixel combination PG always includes first color sub-pixels, second color sub-pixels, third color sub-pixels, and fourth color sub-pixels, and the nominal centroid NP of the sub-pixel combination PG corresponding to the four shift states does not coincide with each other, forming four non-coincident equivalent centroids.

[0108] Embodiments of this application also provide a driving method for a display device, the display device including a display panel, the display panel including a plurality of sub-pixels PX arranged in an array. The plurality of sub-pixels PX includes a first color sub-pixel, a second color sub-pixel, a third color sub-pixel, and a fourth color sub-pixel, the third color sub-pixel and the fourth color sub-pixel having different emission peak wavelengths. The plurality of sub-pixels PX are arranged in alternating columns of first color pixels, second type pixels, second color pixels, and second type pixels along a second direction D2. The first color pixel column includes first color sub-pixels arranged along a first direction D1. The second color pixel column includes second color sub-pixels arranged along the first direction D1. The second type pixel column includes third color sub-pixels and fourth color sub-pixels arranged alternately along the first direction D1. Adjacent pixel columns are staggered relative to each other by a second predetermined distance in the first direction D1.

[0109] The driving method includes: Acquire target image data; Four subframe image data are generated sequentially within a time period based on the target image data. Image data corresponding to the same target location in the target image data are assigned to four different subpixel combinations PG located at four different positions. These four different positions are arranged in two rows and two columns on the display panel. Within different subframe image data, image data corresponding to the same target location in the target image data are assigned to different subpixel combinations PG located at different positions on the display panel. The nominal centroid NP of the subpixel combinations PG in different subframe images does not coincide. The display panel is driven to display multiple subframe images sequentially based on the image data of multiple subframes.

[0110] Example 4 like Figure 11 As shown, Embodiment 4 of this application provides a display device, which includes a display panel and a driving circuit.

[0111] The display panel includes multiple sub-pixels PX arranged in an array. Each sub-pixel PX includes a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The first color sub-pixel is a red sub-pixel R, the second color sub-pixel is a blue sub-pixel B, and the third color sub-pixel is a green sub-pixel G. The sub-pixel PX is rectangular in shape.

[0112] Multiple subpixels PX are arranged in alternating first and second type pixel columns. The first type pixel column includes first-color subpixels and third-color subpixels arranged alternately along a first direction D1. The second type pixel column includes second-color subpixels arranged continuously along the first direction D1. The first direction D1 is the vertical direction. Along the first direction D1, the size of a second-color subpixel is equal to the sum of the sizes of a first-color subpixel and a third-color subpixel.

[0113] The first and second pixel columns are arranged alternately along the second direction D2. The second direction D2 is a horizontal direction and is perpendicular to the first direction D1. In the first pixel column, the first color sub-pixels and the third color sub-pixels are arranged alternately along the first direction D1. In the second pixel column, the second color sub-pixels are arranged continuously along the first direction D1. The first and second pixel columns are aligned along the second direction D2.

[0114] The driving circuit is configured to acquire target image data, sequentially generate multiple sub-frame image data based on the target image data, and sequentially drive the display panel to display multiple sub-frame images within a time period based on the multiple sub-frame image data. In different sub-frame image data, image data corresponding to the same target position in the target image data are assigned to sub-pixel combinations PG located at different positions in the display panel, and the nominal centroids NP of the sub-pixel combinations PG in different sub-frame images do not coincide.

[0115] The subpixel group PG includes a first color subpixel, a second color subpixel, and a third color subpixel. The driving circuit is configured to distribute image data corresponding to the same target position to the subpixel group PG located at six different positions in the six subframe images, and sequentially drive the display panel to display the six subframe images within a time period. The six different positions are arranged in two rows and three columns in the display panel.

[0116] The driving circuit is configured to decompose the image data at each target location in the target image data into a first color component, a second color component, and a third color component. In each subframe image data, the driving circuit allocates the first color component, the second color component, and the third color component according to the positions of the first color subpixel, the second color subpixel, and the third color subpixel in the subpixel combination PG.

[0117] like Figure 12As shown, the driving circuit combines two effective offset states laterally with three effective offset states vertically to form six combined offset states. The six combined offset states are (0,0), (1,0), (0,1), (1,1), (0,2), and (1,2). The combined offset state (0,0) corresponds to the reference offset state. The combined offset state (1,0) represents the width of offsetting one sub-pixel PX in the second direction D2. The combined offset state (0,1) represents the height of offsetting one sub-pixel PX in the first direction D1. The combined offset state (1,1) represents the width of offsetting one sub-pixel PX in the second direction D2 and the height of offsetting one sub-pixel PX in the first direction D1. The combined offset state (0,2) represents the height of offsetting two sub-pixels PX in the first direction D1. The combined offset state (1,2) represents the width of offsetting one sub-pixel PX in the second direction D2 and the height of offsetting two sub-pixels PX in the first direction D1.

[0118] In the first subframe image, image data corresponding to the same target position in the target image data is assigned to a subpixel combination PG located at the first position. This subpixel combination PG includes a first color subpixel R[i,j], a third color subpixel G[i,j+1], and a second color subpixel B[i+1,j], forming a baseline offset state. In the second subframe image, this subpixel combination PG is shifted relative to the first position in the second direction D2 by the width of one subpixel PX, including the second color subpixel B[i+1,j], the first color subpixel R[i+2,j], and the third color subpixel G[i+2,j+1], forming a first horizontal offset state. In the third subframe image, this subpixel combination PG is shifted relative to the first position in the first direction D1 by the height of one subpixel PX, including the third color subpixel G[i,j+1], the first color subpixel R[i,j+2], and the second color subpixel B[i+1,j], forming a first vertical offset state. In the fourth subframe image, the subpixel combination PG is shifted relative to the first position by the width of one subpixel PX in the second direction D2 and by the height of one subpixel PX in the first direction D1, including the second color subpixel B[i+1, j], the third color subpixel G[i+2, j+1], and the first color subpixel R[i+2, j+2], forming a first horizontal and vertical offset state. In the fifth subframe image, the subpixel combination PG is shifted relative to the first position by the height of two subpixels PX in the first direction D1, including the first color subpixel R[i, j+2], the third color subpixel G[i, j+3], and the second color subpixel B[i+1, j+2], forming a second vertical offset state. In the sixth subframe image, the subpixel combination PG is shifted relative to the first position by the width of one subpixel PX in the second direction D2 and by the height of two subpixels PX in the first direction D1, including the second color subpixel B[i+1, j+2], the first color subpixel R[i+2, j+2] and the third color subpixel G[i+2, j+3], forming the second horizontal and vertical combination offset state.

[0119] like Figure 13 As shown, in the initial state, the nominal centroid NP of the image data corresponding to the same target location in the target image data is a spatial point. In the six-fold offset state multiplexing mode, the driving circuit sequentially outputs six sub-frame images, and the image data of the same target location forms six non-coincident equivalent centroids arranged in two rows and three columns in the six sub-frame images.

[0120] Within one time cycle, the driving circuit sequentially drives the display panel to display six sub-frame images. When displaying the first sub-frame image, the driving circuit drives the first color sub-pixel R[i,j], the third color sub-pixel G[i,j+1], and the second color sub-pixel B[i+1,j] to emit light. When displaying the second sub-frame image, the driving circuit drives the second color sub-pixel B[i+1,j], the first color sub-pixel R[i+2,j], and the third color sub-pixel G[i+2,j+1] to emit light. When displaying the third sub-frame image, the driving circuit drives the third color sub-pixel G[i,j+1], the first color sub-pixel R[i,j+2], and the second color sub-pixel B[i+1,j] to emit light. When displaying the fourth sub-frame image, the driving circuit drives the second color sub-pixel B[i+1,j], the third color sub-pixel G[i+2,j+1], and the first color sub-pixel R[i+2,j+2] to emit light. When displaying the fifth subframe image, the driving circuit drives the first color subpixel R[i, j+2], the third color subpixel G[i, j+3], and the second color subpixel B[i+1, j+2] to emit light. When displaying the sixth subframe image, the driving circuit drives the second color subpixel B[i+1, j+2], the first color subpixel R[i+2, j+2], and the third color subpixel G[i+2, j+3] to emit light.

[0121] Since the first type of pixel column includes alternating first-color sub-pixels and third-color sub-pixels along the first direction D1, and the second type of pixel column includes continuously arranged second-color sub-pixels along the first direction D1, the size of a second-color sub-pixel along the first direction D1 is equal to the sum of the sizes of a first-color sub-pixel and a third-color sub-pixel. When the driving circuit causes the sub-pixel combination PG to shift sequentially along the second direction D2, two effective lateral shift states are formed. When the driving circuit causes the sub-pixel combination PG to shift sequentially along the first direction D1, three effective vertical shift states are formed. The two effective lateral shift states and the three effective vertical shift states are combined in pairs to form six combined shift states, thereby forming six non-coincident equivalent centroids within one time period.

[0122] Embodiments of this application also provide a driving method for a display device, the display device including a display panel, the display panel including a plurality of sub-pixels PX arranged in an array. The plurality of sub-pixels PX includes a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The plurality of sub-pixels PX are arranged in alternating first type pixel columns and second type pixel columns. The first type pixel column includes first color sub-pixels and third color sub-pixels arranged alternately along a first direction D1. The second type pixel column includes second color sub-pixels arranged continuously along the first direction D1. Along the first direction D1, the size of a second color sub-pixel is equal to the sum of the sizes of a first color sub-pixel and a third color sub-pixel.

[0123] The driving method includes: Acquire target image data; Six subframe image data are generated sequentially within a time period based on the target image data. Image data corresponding to the same target location in the target image data are assigned to six different subpixel combinations PG located at different positions. Each subpixel combination PG includes a first-color subpixel, a second-color subpixel, and a third-color subpixel. The six different positions are arranged in two rows and three columns on the display panel. In different subframe image data, image data corresponding to the same target location in the target image data are assigned to different subpixel combinations PG on the display panel. The nominal centroid NP of each subpixel combination PG in different subframe images does not overlap. The display panel is driven to display multiple subframe images sequentially based on the image data of multiple subframes.

[0124] Example 5 like Figure 14 As shown, Embodiment 5 of this application provides a display device, which includes a display panel and a driving circuit.

[0125] The display panel includes multiple sub-pixels PX arranged in an array. Each sub-pixel PX includes a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The first color sub-pixel is a red sub-pixel R, the second color sub-pixel is a blue sub-pixel B, and the third color sub-pixel is a green sub-pixel G. The sub-pixel PX has a regular hexagonal shape.

[0126] Multiple sub-pixels PX are arranged into multiple pixel columns, with adjacent pixel columns offset by half the height of a sub-pixel PX along the first direction D1. Within each pixel column, the first-color sub-pixel, the third-color sub-pixel, and the second-color sub-pixel are arranged sequentially and repeatedly along the first direction D1. The first direction D1 is the vertical direction.

[0127] The first pixel column includes a first-color sub-pixel, a second-color sub-pixel, and a third-color sub-pixel arranged in a repeating pattern along the first direction D1. The second pixel column includes a second-color sub-pixel, a third-color sub-pixel, and a first-color sub-pixel arranged in a repeating pattern along the first direction D1. The third pixel column includes a first-color sub-pixel, a second-color sub-pixel, and a third-color sub-pixel arranged in a repeating pattern along the first direction D1. The first, second, third, and fourth pixel columns are arranged in a repeating pattern along the second direction D2. The second direction D2 is a horizontal direction and is perpendicular to the first direction D1. Adjacent pixel columns are staggered by half the height of a sub-pixel PX along the first direction D1, such that the sub-pixels PX in adjacent columns interlock, and any three adjacent sub-pixels PX form a triangular sub-pixel cluster containing one first-color sub-pixel, one third-color sub-pixel, and one second-color sub-pixel.

[0128] The driving circuit is configured to acquire target image data, sequentially generate multiple sub-frame image data based on the target image data, and sequentially drive the display panel to display multiple sub-frame images within a time period based on the multiple sub-frame image data. In different sub-frame image data, image data corresponding to the same target position in the target image data are assigned to sub-pixel combinations PG located at different positions in the display panel, and the nominal centroids NP of the sub-pixel combinations PG in different sub-frame images do not coincide.

[0129] The subpixel group PG comprises a first color subpixel, a third color subpixel, and a second color subpixel. The driving circuit is configured to distribute image data corresponding to the same target position to the subpixel groups PG located at twelve different positions in the twelve subframe images, and sequentially drive the display panel to display the twelve subframe images within a time period. The twelve different positions are arranged in two rows and six columns in the display panel.

[0130] The driving circuit is configured to decompose the image data at each target location in the target image data into a first color component, a second color component, and a third color component. In each subframe image data, the driving circuit allocates the first color component, the second color component, and the third color component according to the positions of the first color subpixel, the second color subpixel, and the third color subpixel in the subpixel combination PG.

[0131] like Figure 15As shown, the driving circuit employs two effective offset states in the lateral direction and six effective offset states in the longitudinal direction. The two effective lateral offset states consist of two lateral offset states that are staggered sequentially. The six effective longitudinal offset states consist of six longitudinal offset states that are staggered sequentially. The driving circuit combines the two effective lateral offset states and the six effective longitudinal offset states in pairs to form twelve combined offset states.

[0132] Within one time period, the driving circuit sequentially outputs twelve sub-frame images. For each vertical offset state, the driving circuit outputs two sub-frame images corresponding to the first horizontal offset state and the second horizontal offset state, respectively. In the first sub-frame image, image data corresponding to the same target position of the target image data is assigned to the sub-pixel combination PG located at the first position. This sub-pixel combination PG includes a first color sub-pixel R[i,j], a second color sub-pixel B[i,j+1], and a third color sub-pixel G[i+1,j+1]. In the second sub-frame image, this sub-pixel combination PG is offset relative to the first position in the second direction D2, and includes the third color sub-pixel G[i+1,j+1], the first color sub-pixel R[i+2,j], and the second color sub-pixel B[i+2,j+1]. In the third sub-frame image, this sub-pixel combination PG is offset relative to the first position in the first direction D1, and includes the second color sub-pixel B[i,j+1], the third color sub-pixel G[i,j+2], and the first color sub-pixel R[i+1,j+2]. In subsequent subframe images, the subpixel combination PG is shifted sequentially in the second direction D2 and the first direction D1, covering combinations of first color subpixels, second color subpixels and third color subpixels at different positions.

[0133] like Figure 16 As shown, in the initial state, the nominal centroid NP of the image data corresponding to the same target location in the target image data is a spatial point. In the twelve-fold offset state multiplexing mode, the driving circuit sequentially outputs twelve sub-frame images, and the image data of the same target location forms twelve non-coincident equivalent centroids arranged in two rows and six columns in the twelve sub-frame images.

[0134] Within one time cycle, the driving circuit sequentially drives the display panel to display twelve sub-frame images. When displaying each sub-frame image, the driving circuit drives the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel at the corresponding position to emit light.

[0135] Since multiple sub-pixels PX are arranged into multiple pixel columns, adjacent pixel columns are offset by half the height of a sub-pixel PX along the first direction D1. Within each pixel column, the first-color sub-pixel, the third-color sub-pixel, and the second-color sub-pixel alternate along the first direction D1, such that any three adjacent sub-pixels PX form a triangular sub-pixel cluster containing one first-color sub-pixel, one third-color sub-pixel, and one second-color sub-pixel. When the driving circuit causes the sub-pixel combination PG to shift sequentially along the second direction D2, two effective lateral shift states are formed. When the driving circuit causes the sub-pixel combination PG to shift sequentially along the first direction D1, six effective vertical shift states are formed. The two effective lateral shift states and the six effective vertical shift states are combined in pairs to form twelve combined shift states, thus forming twelve non-coincident equivalent centroids within one time period.

[0136] Embodiments of this application also provide a driving method for a display device, the display device including a display panel, the display panel including a plurality of sub-pixels PX arranged in an array. The plurality of sub-pixels PX includes a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The plurality of sub-pixels PX are arranged into a plurality of pixel columns, and adjacent pixel columns are offset by half the height of a sub-pixel PX in a first direction D1. In each pixel column, the first color sub-pixel, the third color sub-pixel, and the second color sub-pixel are arranged sequentially and repeatedly along the first direction D1.

[0137] The driving method includes: Acquire target image data; Based on the target image data, twelve sub-frame image data are generated sequentially within a time period. Image data corresponding to the same target location in the target image data are assigned to twelve different sub-pixel combinations PG located at different positions. Each sub-pixel combination PG contains a first-color sub-pixel, a third-color sub-pixel, and a second-color sub-pixel. The twelve different positions are arranged in two rows and six columns on the display panel. In different sub-frame image data, image data corresponding to the same target location in the target image data are assigned to different sub-pixel combinations PG located at different positions on the display panel. The nominal centroid NP of each sub-pixel combination PG in different sub-frame images does not overlap. The display panel is driven to display multiple subframe images sequentially based on the image data of multiple subframes.
