[0058] The present disclosure provides a display device, which includes a display panel and a control component for driving a display module. Figure 1 It exemplifies a schematic diagram of the structure of a liquid crystal display device in one embodiment of the present disclosure; in Figure 1In the example, the display panel is a liquid crystal display panel, and the display device further includes a backlight module BLU that cooperates with the liquid crystal display panel. The control component CTR drives the liquid crystal display panel and the backlight module BLU simultaneously. In other examples of the present disclosure, the display panel can also be other types of display panels, such as an OLED (organic light-emitting diode) display panel, a Micro LED (micro light-emitting diode) display panel, a QD-OLED (quantum dot-organic light-emitting diode) display panel, a QLED (quantum dot light-emitting diode) display panel, a PLED (polymer organic light-emitting diode) display panel, an LED (light-emitting diode) display panel, or other active light-emitting display panels.

[0059] In an embodiment of the present disclosure, taking the display device as a liquid crystal display device as an example, the structure, function, and driving method of the display device of the present disclosure are introduced exemplarily.

[0060] From the perspective of the stacked structure, the liquid crystal display panel may include an array substrate and a color filter substrate that are stacked in sequence. A liquid crystal cell surrounded by sealant is provided between the array substrate and the color filter substrate, and liquid crystal is provided in the liquid crystal cell. Among them, the liquid crystal display panel further includes a first polarizer located on the side of the array substrate away from the color filter substrate and a second polarizer located on the side of the color filter substrate away from the array substrate. Pixel electrodes and pixel driving circuits for applying data voltages to the pixel electrodes are provided on the array substrate. A common electrode is provided on the array substrate or the color filter substrate. By controlling the electric field strength between the pixel electrode and the common electrode, the twisting degree or the lodging degree of the liquid crystal within the corresponding range of the pixel electrode can be adjusted, and then the polarization direction of the polarized light passing through the liquid crystal can be adjusted, and finally the light transmittance of the liquid crystal display panel within the corresponding range of the pixel electrode can be adjusted.

[0061] Figure 2FIG. 0 shows a schematic structural diagram of a liquid crystal display panel PNL according to an embodiment of the present disclosure. From a planar perspective, the liquid crystal display panel PNL may include a display area AA and a peripheral area BB surrounding the display area AA. In the display area AA, the array substrate is provided with gate lines GTW extending in the row direction and data lines DataW extending in the column direction. The gate lines GTW and the data lines DataW define a plurality of pixel areas, and a pixel electrode and a pixel driving circuit may be located in the pixel areas. In an example, the pixel driving circuit may be a thin film transistor serving as a switching transistor. One end of the switching transistor is electrically connected to the data line DataW, the other end of the switching transistor is connected to the pixel electrode, and the gate of the switching transistor is connected to the gate line GTW. The peripheral area BB of the array substrate has a first peripheral area B1 for bonding the source driver integrated circuit SIC, and a second peripheral area B2 for providing the gate driver integrated circuit GOA. Among them, the first peripheral area B1 is located at one end of the array substrate in the column direction, and the second peripheral area B2 is located at one end of the array substrate in the row direction. Among them, the gate driver integrated circuit GOA is electrically connected to each gate line GTW, and is configured to load a scan signal that turns on the switching transistor to the gate line GTW. The source driver integrated circuit SIC is electrically connected to the data line DataW, and is configured to generate a data voltage according to the picture synchronization data and load it to the data line DataW.

[0062] Referring to Figure 2 , in this example, the number of source driver integrated circuits SIC of the liquid crystal display panel PNL is multiple, and each source driver integrated circuit SIC can drive multiple data lines DataW respectively. Further, the source driver integrated circuit SIC is a chip; the array substrate is provided with an FPC (flexible printed circuit) bonding area and a source driver integrated circuit bonding area in the first peripheral area B1. The source driver integrated circuit bonding area can bond the source driver integrated circuit SIC, and the source driver integrated circuit bonding area is electrically connected to the data line DataW and the FPC bonding area through traces respectively. The FPC bonding area can be bonded and connected to the control component CTR through the FPC. In this way, the signals and voltages of the control component CTR can be transmitted to the source driver integrated circuit SIC through the FPC. Further, the signals between the source driver integrated circuit SIC and the control component CTR can be LVDS (low voltage differential signal) signals or mini LVDS signals to reduce signal crosstalk.

[0063] Of course, in other embodiments of the present disclosure, the liquid crystal display panel PNL may also have other structures. For example, the gate driving circuit GOA may not be provided on the array substrate, but a gate driving circuit board may be additionally bonded; for another example, the gate driving circuit GOA may be provided on both sides of the array substrate in the row direction to reduce the voltage drop of the scanning signal or increase the scanning frequency; for another example, the source driving circuits SIC may be provided at both ends of the array substrate in the column direction to drive both sides of the liquid crystal display panel PNL, reducing the voltage drop on the data line DataW in the large-size liquid crystal display panel PNL, especially reducing the voltage drop on the data line DataW in the tiled screen. For another example, the source driving circuit SIC may not be provided on the liquid crystal display panel PNL, but on the COF (chip on film). The present disclosure does not limit the relative positional relationship and setting form between the source driving circuit SIC and the display panel PNL, as long as the source driving circuit SIC can directly drive each pixel in the display area of the PNL.

[0064] It can be understood that when the display panel is an active light-emitting display panel such as an OLED display panel, a QLED display panel, or a Micro LED display panel, the display panel may include an array substrate provided with a pixel driving circuit and a light-emitting element as a sub-pixel, without the need to provide a liquid crystal layer, etc. The structures of the sub-pixels of these display panels, the structure of the pixel driving circuit, and the structure of the wiring may be different from those of the liquid crystal display panel, and the present disclosure does not elaborate on them one by one.

[0065] The backlight module in the example of the embodiment of the present disclosure is a direct-lit backlight module, which includes a lamp board. Figure 3 The structural schematic diagram of the lamp board of the backlight module in the embodiment of the present disclosure is exemplified. Refer to Figure 3 , the lamp board has a lamp area LEDA distributed in an array, and each lamp area LEDA has one or more synchronously controlled light-emitting elements (such as an LED, such as a Mini LED or a Micro LED). Under the control of the control component CTR, the light-emitting brightness of each lamp area LEDA can be independently controlled to cooperate with the picture displayed on the liquid crystal display panel PNL, improving the display effect of the display device. In one example, the control component CTR controls the light-emitting brightness of each lamp area LEDA by controlling the duty cycle of each light-emitting element when it emits light.

[0066] In Figure 3In the example, a microchip MIC can be provided on the lamp board, and each microchip MIC can control one or more light areas LEDA. For example, one microchip MIC controls one light area LEDA or controls four light areas LEDA. The control component CTR can send the light area data of each controlled light area to each microchip MIC. The microchip MIC determines the time ratio (duty cycle) of electrical conduction and electrical interruption of each controlled light area LEDA according to the light area data, and then controls the brightness of each light area LEDA. In other words, the control component CTR can refresh the brightness of each light area by loading the light area data to each microchip MIC.

[0067] For example, in one embodiment, a control unit, a power supply trace for the light zone, a ground trace for the light zone, a data trace, etc. are provided on the light board. Each control unit may include a microchip MIC and a light zone LEDA controlled by the microchip MIC. Each light zone LEDA includes one light-emitting element or multiple light-emitting elements. The multiple light-emitting elements may be connected in parallel, in series, or in a hybrid connection of parallel / series. Among them, the first power terminal of the light zone LEDA is electrically connected to the power supply trace for the light zone, and the second power terminal of the light zone LEDA is electrically connected to the control pin of the microchip MIC. A relatively stable driving voltage (ACC) can be applied to the power supply trace for the light zone, and a ground voltage (GND) can be applied to the ground trace for the light zone. When the microchip MIC controls multiple light zone LEDAs, the control pins connected to each light zone LEDA are different. The microchip MIC is connected to the data trace and the ground trace for the light zone, and is used to receive the light zone data from the control component CTR through the data trace, and control the electrical connection relationship between each control pin and the ground trace for the light zone according to the received light zone data. Under the control of the microchip MIC, when the control pin is electrically connected to the ground trace for the light zone, each light-emitting element in the light zone LEDA connected to the control pin is in a conductive state, and the current on the power supply trace for the light zone flows through the light-emitting element to the ground trace for the light zone, so that each light-emitting element emits light under a substantially constant current. Under the control of the microchip MIC, when the control pin is electrically open-circuited with the ground trace for the light zone, each light-emitting element in the light zone LEDA connected to the control pin is in an open-circuit state, and the current on the power supply trace for the light zone cannot flow through the light-emitting element to the ground trace for the light zone, so that each light-emitting element does not emit light. Thus, under the control of the light zone data, the microchip MIC can control the duty cycle of each light-emitting element in the light zone LEDA by controlling the time ratio of electrical conduction and electrical open-circuit of each control pin, and ultimately reflects the control of the macroscopic brightness of each light zone LEDA. In this embodiment, the control component CTR also needs to apply a working voltage for enabling the microchip MIC to work to the microchip MIC. Among them, the light board can be additionally provided with a chip power supply line to apply the working voltage to the microchip MIC, or the working voltage can be applied to the microchip MIC through the data trace. Exemplarily, the data trace can be multiplexed as the chip power supply line, and then the power line carrier communication technology is used to apply the working voltage and the light zone data to the microchip MIC at the same time.

[0068] In one example, sensors such as a temperature sensor, a brightness sensor, etc. can also be provided on the light board; the sensing signals generated by these sensors can be directly sent to the control component CTR or forwarded to the control component CTR through the microchip MIC, and the control component CTR can directly adjust the working state or working process of the backlight module BLU according to these sensing signals.

[0069] In one example, the lamp board may include a substrate, a driving layer, and an element layer that are sequentially stacked. The driving layer is provided with at least two wiring metal layers, for example, two wiring metal layers containing copper are provided. Between the wiring metal layers, they are isolated by an insulating layer. The insulating layer can be an inorganic insulating layer (such as silicon nitride or silicon oxide) or an organic insulating layer (such as resin), or it can also be a stacked inorganic insulating layer and organic insulating layer. The wiring metal layers can be connected through vias penetrating the insulating layer. A bonding pad can be formed on the surface of the wiring metal layer farthest from the substrate to bond electronic components, such as bonding light-emitting components, microchips MIC, and sensors.

[0070] In one example, the substrate of the lamp board can be a glass substrate. Further, the lamp board can be formed by splicing multiple sub-lamp boards together; the sub-lamp boards are electrically connected to each other, or each sub-lamp board is independently and directly controlled by a control component CTR.

[0071] In one example, the light-emitting colors of the respective light-emitting components are the same, for example, they are all blue light-emitting components. A photoluminescent layer is also provided on the lamp board, for example, a quantum dot film is provided to convert blue light into relatively uniform white light.

[0072] In some examples, the backlight module BLU can also be provided with one or more of a collimating film, a band-pass filter film, a diffuser, a brightness enhancement film, or other optical film materials, which are not limited in the present disclosure.

[0073] It can be understood that the backlight module BLU in the embodiments of the present disclosure can also adopt other structures, for example, using a lamp strip to form a lamp board, and the present disclosure does not introduce these methods one by one.

[0074] In some embodiments of the present disclosure, referring to Figure 4 , the display panel PNL can be used as a splicing unit, and multiple display panels PNL can be spliced into a larger-sized splicing panel PNLA. In this way, the shape of the splicing panel PNLA can be adjusted or the size of the splicing panel PNLA can be increased. In one example, the display panel PNL can be a large-sized display panel PNL, for example, it can be a display panel of 45 inches or larger, specifically, it can be a 55-inch display panel. In another embodiment, the display panel PNL can be a special-shaped panel, for example, it can have multiple different protruding parts.

[0075] Referring to Figure 6 and Figure 7 , the display panel PNL in the embodiments of the present disclosure includes pixels Pix distributed in an array. Any one pixel Pix includes a plurality of sub-pixels SP that are sequentially adjacent in the row direction DH, especially including a plurality of sub-pixels SP that can emit different colors of light. In Figure 6 and Figure 7In the example, pixel Pix includes three different sub-pixels SP, namely the first sub-pixel SPA, the second sub-pixel SPB, and the third sub-pixel SPC, and the light-emitting colors of the three different sub-pixels are different. For example, the first sub-pixel SPA can emit red light and is a red sub-pixel R; the second sub-pixel SPB can emit green light and is a green sub-pixel G; the third sub-pixel SPC can emit blue light and is a blue sub-pixel B. In other examples of the present disclosure, the pixel Pix may include sub-pixels SP of other colors or other numbers of sub-pixels SP.

[0076] See Figure 6 and Figure 7 , the display panel PNL includes a plurality of pixel columns, and any one of the pixel columns includes a plurality of pixels arranged in sequence along the column direction DV. The pixel column includes a plurality of sub-pixel columns VSP, and each sub-pixel column VSP includes a plurality of sub-pixels SP arranged in sequence along the column direction DV.

[0077] In an embodiment of the present disclosure, the display panel PNL of the present disclosure may have a narrow border, and the distance between the edge of the display area AA of the display panel PNL and the edge of the display panel PNL on the corresponding side is very small. For example, on at least one side of the display panel PNL, the distance between the edge of the display area AA of the display panel PNL and the edge of the display panel PNL on this side is less than or equal to 2 mm; exemplarily, the distance between the sub-pixel at the edge of the display panel PNL and the edge of the display panel PNL is between 1.4 and 1.5 mm. For example, on at least one side of the display panel PNL, the distance between the edge of the display area AA of the display panel PNL and the edge of the display panel PNL on this side is less than or equal to 1 mm; exemplarily, the distance between the sub-pixel at the edge of the display panel PNL and the edge of the display panel PNL is between 0.58 mm and 0.68 mm. Specifically, at least one side of the display panel PNL includes the side where the display panels PNL are spliced together. In this way, the width of the non-display area at the splicing position of the display panels PNL is relatively narrow, and the display effect is good.

[0078] For example, on each side of the display panel PNL, the distance between the edge of the display area AA of the display panel PNL and the edge of the display panel PNL on this side is less than or equal to 2 mm; exemplarily, the distance between the sub-pixel at the edge of the display panel PNL and the edge of the display panel PNL is 1.7 mm. For example, on each side of the display panel PNL, the distance between the edge of the display area AA of the display panel PNL and the edge of the display panel PNL on this side is less than or equal to 1 mm; exemplarily, the distance between the sub-pixel at the edge of the display panel PNL and the edge of the display panel PNL is 0.88 mm.

[0079] For example, the edge contour of the display panel PNL is rectangular, the contour of the display area AA is rectangular, and the overall edge contour of the splicing panel PNLA is rectangular.

[0080] When the display panel PNL with a narrow border is applied to a display device, due to the height of the border BR of the display device and the viewing angle, there is a risk that the sub-pixels SP near the edge are blocked by the border BR of the display device. For example, referring to Figure 8 , in an example of the present disclosure, the distance between the sub-pixel column VSP closest to the edge of the display area AA and the border of the display device is very small. Since the border BR has a certain height, when the user views from a large viewing angle, the border BR may block the light emitted by the sub-pixel column VSP, thereby causing the sub-pixel column VSP to be visually blocked by the border BR. It can be understood that in actual use, the display panel PNL is generally placed perpendicular to the horizontal plane. At this time, the borders BR on the left and right sides of the display panel PNL (referring to Figure 8 the relative two sides along the row direction of the pixel Pix) are likely to block the sub-pixel column VSP when the user views from a large viewing angle.

[0081] Figure 5 and Figure 6 show the arrangement of the sub-pixels SP in the pixel Pix in the related art. Referring to Figure 5 and Figure 6 In the related art, the arrangement of the sub-pixels SP in each pixel Pix is the same, which makes the colors of the sub-pixels SP in the same column the same. Exemplarily, in the related art, the sub-pixel arrangement of the pixel Pix can be a Real RGB structure. However, when the display panel PNL in the related art is applied to a display device with a narrow border, the sub-pixel column VSP at the edge of the display panel PNL may be blocked by the border BR of the display device at a large viewing angle. In this case, color deviation is likely to occur at the position near the edge (row direction edge) of the displayed image, such as being reddish or cyanish.

[0082] In order to overcome this defect and enable the display device of the present disclosure to still have a good display effect when having a narrow border, referring to Figure 7 and Figure 8 , in the embodiments of the present disclosure, each sub-pixel SP can be arranged into a plurality of sub-pixel columns VSP. Each sub-pixel column VSP is arranged in sequence along the row direction DH and extends along the column direction DV; each sub-pixel column VSP includes a plurality of sub-pixels SP arranged in the same column. Referring to Figure 7 and Figure 8In an example, in the same sub-pixel column VSP, adjacent sub-pixels SP have different colors. In this way, in the embodiments of the present disclosure, the sub-pixels of the display panel PNL are arranged in a disordered order, that is, the arrangement of the sub-pixels SP of two adjacent pixels Pix along the column direction DV is different. Refer to Figure 8 , even if the sub-pixel column VSP of the display panel PNL of the present disclosure near the border BR of the display device is blocked at a large viewing angle, the remaining sub-pixel columns VSP are not single-color sub-pixel columns VSP, but sub-pixel columns VSP with multiple different color sub-pixels. In this way, it is possible to avoid or effectively reduce display abnormalities at the edge of the displayed image.

[0083] Furthermore, the pixels Pix arranged in the same row have the same sub-pixel SP arrangement.

[0084] In one example, refer to Figure 7 , the arrangement of the sub-pixels SP of the pixel Pix is periodically arranged in a cycle of every three rows. In each cycle, the arrangement of the sub-pixels SP of one row of pixels Pix is the first sub-pixel SPA, the second sub-pixel SPB, and the third sub-pixel SPC arranged in sequence along the row direction DH, the arrangement of the sub-pixels SP of one row of pixels Pix is the second sub-pixel SPB, the third sub-pixel SPC, and the first sub-pixel SPA arranged in sequence along the row direction DH, and the arrangement of the sub-pixels SP of one row of pixels Pix is the third sub-pixel SPC, the first sub-pixel SPA, and the second sub-pixel SPB arranged in sequence along the row direction DH.

[0085] In an example of the embodiments of the present disclosure, the splicing panel PLNA includes a plurality of spliced display panels PNL, and each display panel PNL can be used as a splicing unit of the splicing panel. In order to reduce the width of the splicing line between the display panels PNL, the size of the border of the display panel PNL can be reduced, that is, the display panel PNL has an extremely narrow border. This makes the sub-pixels of the display panel PNL close to the edge of the display panel PNL. On the splicing panel PLNA, the sub-pixels of the splicing panel PLNA are also close to the edge of the splicing panel PLNA, so that the sub-pixels SP close to the edge of the splicing panel PLNA are easily blocked by the border BR of the display device at a large viewing angle. In the embodiments of the present disclosure, by arranging each sub-pixel in a disordered manner, it is possible to avoid the edge turning blue or red caused by the border BR blocking the sub-pixel column VSP. Specifically, the sub-pixel column VSP blocked by the border BR includes sub-pixels SP of various colors, and it will not cause color deviation on the macro scale due to the same color sub-pixels SP being blocked at a large viewing angle for the pixels Pix close to the border BR.

[0086] Under normal circumstances, since the sub-pixels SP of two adjacent pixels Pix in each column of pixels are arranged differently, each column of pixels will present a certain jagged effect when displaying some pictures; this jagged effect is basically invisible under the influence of light mixing of surrounding pixels and will not affect the display effect. However, for some line patterns, such as vertical lines (lines along the column direction), curves or oblique lines (lines with a certain angle to the row direction), if the brightness difference between the line pattern and the adjacent pattern is relatively large, the edge of the line may present a visible jagged shape. For the boundary vertical line between two color block patterns, if the brightness difference between the two color block patterns is large, it will also make the boundary vertical line have a jagged feeling. Exemplarily, in Figure 10 the boundary vertical line between the area FIGD and the area FIGE will present a certain jagged feeling.

[0087] The display device provided by the embodiment of the present disclosure can display a target picture according to the picture data of the received initial picture. The display device is configured to: when the initial picture has at least one feature pattern area, adjust the brightness of at least part of the sub-pixels in the feature pattern area to generate a target picture. In the initial picture, there is a relatively large brightness difference between at least part of the pixels in the feature pattern area and needs to be optimized. The display device provided by the embodiment of the present disclosure can perform gray-scale transition correction on the gray-scale of at least part of the sub-pixels in these feature pattern areas, so that the actually displayed target picture has a better display effect. Specifically, it can eliminate or weaken the jagged feeling generated in the feature pattern area.

[0088] Optionally, after obtaining the feature pattern area, the display device of the present disclosure can determine part of the sub-pixels in the feature pattern area as the correction sub-pixels to be gray-scale corrected, and determine the reference sub-pixels of the correction sub-pixels; according to the gray-scale of the correction sub-pixels in the initial picture and the gray-scale of the reference sub-pixels in the initial picture, determine the gray-scale of the correction sub-pixels in the target picture, for example, make the gray-scale of the correction sub-pixels in the target picture be between the gray-scale of the correction sub-pixels in the initial picture and the gray-scale of the reference sub-pixels in the initial picture, so as to realize the gray-scale transition correction of the correction sub-pixels, and further realize the transition correction of the brightness of the correction sub-pixels, while ensuring the display effect of the pattern in the feature pattern area, eliminate or weaken the jagged feeling at the edge of the pattern.

[0089] In the embodiment of the present disclosure, the correction sub-pixels, the reference sub-pixels of the correction sub-pixels, etc. can be determined according to the arrangement mode of the sub-pixels in the display panel and according to the uncorrected gray-scale of these sub-pixels, and then the gray-scale of the correction sub-pixels can be subjected to gray-scale transition correction.

[0090] In some examples of the present disclosure, the initial frame data may first undergo sub-pixel reordering so that the order of the sub-pixels in the frame data is consistent with the order of the sub-pixels of the display panel; then, based on the reordered frame data, the feature pattern area, the corrected sub-pixels, and the reference sub-pixels are determined.

[0091] In some other embodiments, before determining the feature pattern area, the corrected sub-pixels, and the reference sub-pixels, it may not be necessary to pre-reorder the sub-pixels of the frame data of the initial frame; according to the frame data of the initial frame, even without sub-pixel reordering, the uncorrected gray levels of the respective sub-pixels of the display panel can be determined, and then, based on the uncorrected gray levels of the respective sub-pixels of the display panel, the feature pattern area, the corrected sub-pixels, and the reference sub-pixels can be determined, and further, gray level transition correction of the sub-pixels is performed to obtain the corrected frame data. According to the display requirements of the display panel, the corrected frame data may or may not be subjected to sub-pixel reordering.

[0092] For example, when the display panel can directly drive each sub-pixel according to the frame data without sub-pixel reordering through hardware settings or algorithm settings, the corrected frame data may not need to be subjected to sub-pixel reordering. For example, when the source driver circuit of the display panel is provided with a sub-pixel reordering algorithm or a sub-pixel reordering circuit, the control component CTR can directly send the corrected frame data to the source driver circuit of the display panel without going through the sub-pixel reordering process; the source driver circuit can reorder the corrected frame data and drive each sub-pixel of the display panel in sequence. For another example, when the data lines for driving the sub-pixels in the display panel are pre-designed such that the data voltages generated according to the frame data without sub-pixel reordering can be sequentially loaded onto the correct sub-pixels, the control component CTR can send the corrected frame data to the display panel without going through the sub-pixel reordering process.

[0093] Of course, if the display panel requires the frame data after sub-pixel reordering, then the control component CTR can reorder the corrected frame data, thereby obtaining the corrected and reordered frame data, and sending the corrected and reordered frame data to the display panel.

[0094] In other words, when the required picture data of the display panel is the unreordered picture data due to its algorithm, hardware, or other setting methods, the picture data loaded by the control component CTR to the display panel can be the unreordered picture data. For example, it can be the picture data after gray-scale transition correction and without sub-pixel reordering. When the required picture data of the display panel is the reordered picture data due to its algorithm, hardware, or other setting methods, the picture data loaded by the control component CTR to the display panel can be the reordered picture data. For example, it is the picture data after reordering and gray-scale transition correction; the reordering process of this picture data can be before or after the gray-scale transition correction.

[0095] It can be understood that in the embodiments of the present disclosure, the sub-pixel reordering process can be implemented by a sub-pixel reordering circuit, that is, it can be implemented by the hardware located in the control component CTR or by software. For example, it can be implemented by a sub-pixel reordering algorithm located in the control component CTR.

[0096] In the embodiments of the present disclosure, sub-pixel reordering can adjust the order of the gray scales of at least some sub-pixels in the unordered picture data to obtain the reordered picture data. For example, it can adjust the order of the gray scales of some sub-pixels in the picture data of the initial picture. Among them, in the picture data before reordering (for example, the picture data of the initial picture), the gray scales of each sub-pixel SP are arranged according to the same arrangement method of the sub-pixels SP of each pixel; in the picture data after reordering, the gray scales of the sub-pixels SP of each pixel Pix in the liquid crystal display panel PNL of the present disclosure are arranged according to the arrangement method of the sub-pixels SP of each pixel.

[0097] For example, in the picture data of the initial picture, the data of any one pixel includes the gray scales of three sub-pixels arranged in sequence, that is, the gray scale of the red sub-pixel, the gray scale of the green sub-pixel, and the gray scale of the blue sub-pixel arranged in sequence; in this arrangement method, it is default that the arrangement order of the three types of sub-pixels of red, green, and blue in each pixel is the same, that is, they all maintain the arrangement order of the red sub-pixel SPR, the green sub-pixel SPG, and the blue sub-pixel SPB in sequence. However, in the liquid crystal display panel PNL of the present disclosure, the arrangement methods of the sub-pixels SP of different pixels Pix may be different, and the picture data before reordering cannot be directly applied to the driving of the liquid crystal display panel PNL of the present disclosure. For example, when the sub-pixels SP of a pixel Pix of the present disclosure are arranged in sequence according to the order of the blue sub-pixel SPB, the red sub-pixel SPR, and the green sub-pixel SPG, it is necessary to adjust the arrangement order of the gray scales of each sub-pixel SP according to the actual arrangement method of the sub-pixels SP, so that the data of the pixel Pix after reordering includes the gray scale of the blue sub-pixel, the gray scale of the red sub-pixel, and the gray scale of the green sub-pixel arranged in sequence.

[0098] In an embodiment of the present disclosure, referring to Figure 7 , in the liquid crystal display panel PNL of the display panel according to the embodiment of the present disclosure, each pixel Pix includes a red sub-pixel SPR, a green sub-pixel SPG, and a blue sub-pixel SPB; the arrangement of the sub-pixels SP of the pixel Pix is periodically arranged in a cycle of every three rows. In each cycle, the arrangement of the sub-pixels SP of the pixels Pix in the first row is the red sub-pixel SPR, the green sub-pixel SPG, and the blue sub-pixel SPB arranged in sequence along the row direction DH, the arrangement of the sub-pixels SP of the pixels Pix in the second row is the green sub-pixel SPG, the blue sub-pixel SPB, and the red sub-pixel SPR arranged in sequence along the row direction DH, and the arrangement of the sub-pixels SP of the pixels Pix in the third row is the blue sub-pixel SPB, the red sub-pixel SPR, and the green sub-pixel SPG arranged in sequence along the row direction DH. In the pre-reordering frame data, each pixel Pix data includes the gray levels of the red sub-pixel SPR, the green sub-pixel SPG, and the blue sub-pixel SPB arranged in sequence. The data processing module DHU adjusts the order of the gray levels of the sub-pixels SP in each pixel data in the pre-reordering frame data through a sub-pixel reordering algorithm or a sub-pixel reordering subunit. Since the out-of-order arrangement is a cycle of three rows, the arrangement order of the gray levels of the sub-pixels SP in the pixel data of the first row remains unchanged; the order of the gray levels of the sub-pixels SP in the pixel data of the second row is adjusted to the gray level of the green sub-pixel SPG, the gray level of the blue sub-pixel SPB, and the gray level of the red sub-pixel SPR; the order of the gray levels of the sub-pixels SP in the pixel data of the third row is adjusted to the gray level of the blue sub-pixel SPB, the gray level of the red sub-pixel SPR, and the gray level of the green sub-pixel SPG. The data of the subsequent rows of pixels is cyclically adjusted in the order of these three rows. For example, in the sub-pixel reordering process, only the order of the gray levels of the sub-pixels inside the pixel data is changed, so only the order of the gray levels of the sub-pixels inside the pixel data is adjusted. For example, the sub-pixel reordering algorithm or the sub-pixel reordering subunit UA2 only needs to adjust the order of the gray levels of the sub-pixels inside each pixel data and set a cycle of three rows.

[0099] In the embodiment of the present disclosure, the feature pattern area includes at least one of the first feature pattern area, the second feature pattern area, and the third feature pattern area.

[0100] The first feature pattern area includes a plurality of first feature pixel groups arranged in sequence along the column direction. Each first feature pixel group includes a first feature pixel, a second feature pixel, and a third feature pixel that are adjacent to each other in sequence in the same row. Among them, the brightness difference between the first feature pixel and the second feature pixel is greater than or equal to a brightness threshold; the brightness difference between the third feature pixel and the second feature pixel is greater than or equal to the brightness threshold; and all the first feature pixels are arranged in the same column.

[0101] The second feature pattern area includes a plurality of second feature pixel groups arranged in sequence along the column direction. Each second feature pixel group includes a fourth feature pixel, a fifth feature pixel, and a sixth feature pixel that are adjacent to each other in sequence in the same row. Among them, the brightness difference between the fourth feature pixel and the fifth feature pixel is greater than or equal to the brightness threshold; the brightness difference between the sixth feature pixel and the fifth feature pixel is less than the brightness threshold; and all the fourth feature pixels are arranged in the same column.

[0102] In an embodiment of the present disclosure, the third feature pattern area includes a first sub-pixel group, a second sub-pixel group, and a third sub-pixel group that are adjacent to each other in sequence along the row direction. The second sub-pixel group includes 3 sub-pixels that are adjacent to each other in sequence along the row direction. The first sub-pixel group and the third sub-pixel group each include a plurality of sub-pixels that are adjacent to each other in sequence along the row direction. In the first sub-pixel group, the gray levels of all sub-pixels of the same color are the same, and the number of any one kind of sub-pixels of the same color is N1. In the third sub-pixel group, the gray levels of all sub-pixels of the same color are the same, and the number of any one kind of sub-pixels of the same color is N2. Both N1 and N2 are positive integers from 1 to 1000. The brightness difference between the pixels of the second sub-pixel group and the pixels of the first sub-pixel group is greater than or equal to the brightness threshold. The brightness difference between the pixels of the second sub-pixel group and the pixels of the third sub-pixel group is greater than or equal to the brightness threshold.

[0103] In another embodiment, in the third feature pattern area, the number of sub-pixels in the second sub-pixel group may not be only 3, but may be in the range of 3 to 5. In other words, the third feature pattern area includes a first sub-pixel group, a second sub-pixel group, and a third sub-pixel group that are adjacent to each other in sequence along the row direction. The second sub-pixel group includes 3 to 5 sub-pixels that are adjacent to each other in sequence along the row direction. For example, in this embodiment, the gray levels of all sub-pixels in the second sub-pixel group are the same.

[0104] Therefore, the display device can be configured to adjust one or more of the first feature pattern region, the second feature pattern region, and the third feature pattern region as the feature pattern region. It can be understood that when one or more of the first feature pattern region, the second feature pattern region, and the third feature pattern region are not used as the feature pattern region, they may not be adjusted according to the method or adjustment effect provided in the embodiments of the present disclosure. For example, in another embodiment of the present disclosure, there may be a first feature pattern region in the initial screen, but in this embodiment, the first feature pattern region may not be used as the feature pattern region for sub-pixel transition correction. In another embodiment of the present disclosure, there may be a second feature pattern region in the initial screen, but in this embodiment, the second feature pattern region may not be used as the feature pattern region for sub-pixel transition correction. In another embodiment of the present disclosure, there may be a third feature pattern region in the initial screen, but in this embodiment, the third feature pattern region may not be used as the feature pattern region for sub-pixel transition correction.

[0105] In an embodiment of the present disclosure, when the first feature pattern region is adjusted as the feature pattern region, Gx(SA1) is located between G(SA1) and G(SA10); where Gx(SA1) is the gray scale of the first corrected sub-pixel in the target screen, G(SA1) is the gray scale of the first corrected sub-pixel in the initial screen, and G(SA10) is the gray scale of the reference sub-pixel of the first corrected sub-pixel; according to the arrangement of the sub-pixels on the display panel, the first corrected sub-pixel is the sub-pixel of the first feature pixel that is close to the second feature pixel; the reference sub-pixel of the first corrected sub-pixel is the sub-pixel that is located in the second feature pixel adjacent to the first corrected sub-pixel and has the same color as the first corrected sub-pixel; Gx(SA2) is located between G(SA2) and G(SA20); Gx(SA2) is the gray scale of the second corrected sub-pixel in the target screen, G(SA2) is the gray scale of the second corrected sub-pixel in the initial screen, and G(SA20) is the gray scale of the reference sub-pixel of the second corrected sub-pixel; according to the arrangement of the sub-pixels on the display panel, the second corrected sub-pixel is the sub-pixel of the third feature pixel that is close to the second feature pixel; the reference sub-pixel of the second corrected sub-pixel is the sub-pixel that is located in the second feature pixel adjacent to the second corrected sub-pixel and has the same color as the second corrected sub-pixel.

[0106] In another embodiment, the gray levels of the sub-pixels of the first characteristic pixel are the same; the gray levels of the sub-pixels of the second characteristic pixel are the same; the gray levels of the sub-pixels of the third characteristic pixel are the same. At this time, the reference sub-pixel of the first correction sub-pixel is not necessarily the sub-pixel that is located in the second characteristic pixel adjacent to the first correction sub-pixel and has the same color as the first correction sub-pixel. Exemplarily, the reference sub-pixel of the first correction sub-pixel can be any one or more sub-pixels located in the second characteristic pixel adjacent to the first correction sub-pixel, or the sub-pixels located in the second characteristic pixel and adjacent to the first correction sub-pixel. Similarly, the reference sub-pixel of the second correction sub-pixel is not necessarily the sub-pixel that is located in the second characteristic pixel adjacent to the second correction sub-pixel and has the same color as the second correction sub-pixel. Exemplarily, the reference sub-pixel of the second correction sub-pixel is any one or more sub-pixels located in the second characteristic pixel adjacent to the second correction sub-pixel, or the sub-pixels located in the second characteristic pixel and adjacent to the second correction sub-pixel.

[0107] It can be understood that any number of sub-pixels includes all sub-pixels, and these sub-pixels have a common gray level. Therefore, for example, making the reference sub-pixel of the first correction sub-pixel be any number of sub-pixels located in the second characteristic pixel adjacent to the first correction sub-pixel includes: making the reference sub-pixel of the first correction sub-pixel be the common gray level of the sub-pixels located in the second characteristic pixel adjacent to the first correction sub-pixel.

[0108] In an embodiment of the present disclosure, when the second characteristic pattern area is adjusted as the characteristic pattern area, Gx(SB1) is located between G(SB1) and G(SB10); Gx(SB1) is the gray level of the third correction sub-pixel in the target screen, G(SB1) is the gray level of the third correction sub-pixel in the initial screen, and G(SB10) is the gray level of the reference sub-pixel of the third correction sub-pixel; according to the arrangement manner of the sub-pixels on the display panel, the third correction sub-pixel is the sub-pixel in the fourth characteristic pixel that is close to the fifth characteristic pixel; the reference sub-pixel of the third correction sub-pixel is the sub-pixel that is located in the fifth characteristic pixel adjacent to the third correction sub-pixel and has the same color as the third correction sub-pixel.

[0109] In another embodiment, the gray levels of the sub-pixels of the fourth feature pixel are the same; the gray levels of the sub-pixels of the fifth feature pixel are the same; the gray levels of the sub-pixels of the sixth feature pixel are the same. At this time, the reference sub-pixel of the third correction sub-pixel is not necessarily the sub-pixel that is located in the fifth feature pixel adjacent to the third correction sub-pixel and has the same color as the third correction sub-pixel. Exemplarily, the reference sub-pixel of the third correction sub-pixel is any one or more sub-pixels located in the fifth feature pixel adjacent to the third correction sub-pixel, or is the sub-pixel located in the fifth feature pixel and adjacent to the third correction sub-pixel.

[0110] In an embodiment of the present disclosure, when the third feature pattern area is adjusted as a feature pattern area, if the number of sub-pixels in the second sub-pixel group is only 3, it is possible to make Gx(SC1) located between G(SC1) and G(SC10); Gx(SC1) is the gray level of the fourth correction sub-pixel in the target screen, G(SC1) is the gray level of the fourth correction sub-pixel in the initial screen, and G(SC10) is the gray level of the reference sub-pixel of the fourth correction sub-pixel; according to the arrangement manner of the sub-pixels on the display panel, the fourth correction sub-pixel is the sub-pixel in the first sub-pixel group close to the second sub-pixel group; the reference sub-pixel of the fourth correction sub-pixel is the sub-pixel in the second sub-pixel group having the same color as the fourth correction sub-pixel; Gx(SC2) is located between G(SC2) and G(SC20); Gx(SC2) is the gray level of the fifth correction sub-pixel in the target screen, G(SC2) is the gray level of the fifth correction sub-pixel in the initial screen, and G(SC20) is the gray level of the reference sub-pixel of the fifth correction sub-pixel; according to the arrangement manner of the sub-pixels on the display panel, the fifth correction sub-pixel is the sub-pixel in the third sub-pixel group close to the second sub-pixel group; the reference sub-pixel of the fifth correction sub-pixel is the sub-pixel in the second sub-pixel group having the same color as the fifth correction sub-pixel.

[0111] In another embodiment, if the gray levels of the sub-pixels in the second sub-pixel group are the same, then the reference sub-pixel of the fourth correction sub-pixel is not necessarily the sub-pixel in the second sub-pixel group that has the same color as the fourth correction sub-pixel. Exemplarily, the reference sub-pixel of the fourth correction sub-pixel can be any one or more sub-pixels located in the second sub-pixel group, or can be the sub-pixel located in the second sub-pixel group and adjacent to the fourth correction sub-pixel. Similarly, the reference sub-pixel of the fifth correction sub-pixel is not necessarily the sub-pixel in the second sub-pixel group that has the same color as the fifth correction sub-pixel. Exemplarily, the reference sub-pixel of the fifth correction sub-pixel is any one or more sub-pixels located in the second sub-pixel group, or is the sub-pixel located in the second sub-pixel group and adjacent to the fifth correction sub-pixel.

[0112] In another embodiment, if the number of sub-pixels in the second sub-pixel group is not limited to only 3, for example, the number of sub-pixels in the second sub-pixel group can be 3 to 5, then the gray levels of the sub-pixels in the second sub-pixel group can be simultaneously defined as the same. At this time, the reference sub-pixel of the fourth correction sub-pixel can be any one or more sub-pixels located in the second sub-pixel group, or is the sub-pixel located in the second sub-pixel group and adjacent to the fourth correction sub-pixel. The reference sub-pixel of the fifth correction sub-pixel can be any one or more sub-pixels located in the second sub-pixel group, or is the sub-pixel located in the second sub-pixel group and adjacent to the fifth correction sub-pixel.

[0113] In other words, the present disclosure provides a variety of different embodiments. In some embodiments, it is not necessarily defined that the characteristic pixel is a gray pixel (a gray pixel means that the gray levels of the sub-pixels of the pixel are the same, including black, gray, and white); at this time, the reference sub-pixel of the correction sub-pixel can be the sub-pixel having the same color as the correction sub-pixel. In other embodiments, if it is defined that only gray pixels can be used as characteristic pixels, then the reference sub-pixel of the correction sub-pixel can also be sub-pixels of other colors rather than necessarily sub-pixels of the same color.

[0114] In some embodiments, the second sub-pixel group only includes three sub-pixels. In this way, when there are multiple third feature pattern regions adjacent to each other and located in different pixel rows, the second sub-pixel groups of these third feature pattern regions can form a line (such as an oblique line or a curve), and the slope of this line (the angle with the pixel row direction) is large. Since it is difficult to display a curve or a line with a small slope on a single pixel row with less than 3 sub-pixels, the display effect of a curve or an oblique line with a small slope can be optimized without relying on this embodiment. In some other embodiments, the number of second sub-pixel groups in the third feature pattern region may be more than 3, for example, it may be 3 to 5. In this embodiment, at least some curves and lines with small slopes can have their display effects optimized.

[0115] For example, the cases where the colors of the sub-pixels are the same include that the sub-pixels are all red, all green, or all blue.

[0116] The present disclosure also provides a control component for a display device. Refer to Figure 11 , the control component includes a data processing module, and the data processing module includes a data acquisition unit UA, a feature pattern region acquisition unit UB, a transition correction unit UC, and a data output unit UD.

[0117] The data acquisition unit UA is configured to acquire picture data; exemplarily, the picture data includes the gray levels of the sub-pixels of each pixel. This picture data can be the picture data before sorting or the picture data after sorting.

[0118] The feature pattern region acquisition unit UB is configured to acquire a feature pattern region according to the picture data, for example, acquire at least one of the first feature pattern region, the second feature pattern region, and the third feature pattern region as the feature pattern region.

[0119] The transition correction unit UC is configured to use at least some of the sub-pixels in the feature pattern region as corrected sub-pixels, and perform gray level transition correction on the corrected sub-pixels to achieve adjustment of the feature pattern region. Among them, when determining the corrected sub-pixels and the reference sub-pixels of the corrected sub-pixels, it is determined according to the arrangement manner of the sub-pixels on the display panel.

[0120] The data output unit UD is configured to drive the liquid crystal display panel according to the gray levels of the corrected sub-pixels in the feature pattern region after correction.

[0121] The present disclosure also provides a driving method for a display device. Refer to Figure 13 , the driving method of the display device may include the steps shown in step S110 to step S140.

[0122] Step S110, acquire picture data;

[0123] Step S120: Obtain a feature pattern area according to the screen data.

[0124] Step S130: Use at least some of the sub-pixels in the feature pattern area as corrected sub-pixels, and perform grayscale transition correction on the corrected sub-pixels to adjust the feature pattern area.

[0125] Step S140: Drive the liquid crystal display panel according to the grayscale of the corrected sub-pixels in the feature pattern area after correction.

[0126] As follows, with reference to the accompanying drawings, the display device, control component, and driving method provided by the embodiments of the present disclosure will be further exemplarily described.

[0127] Figure 12 The flowchart of a driving method is exemplified. In this example, sub-pixel reordering is performed first, and then grayscale transition correction is performed. In this example, the screen data of the initial screen forms reordered screen data after sub-pixel reordering; this reordered screen data is used to obtain the feature pattern area and perform grayscale transition correction on the corrected sub-pixels. When the feature pattern area can be obtained according to the reordered screen data, grayscale transition correction is performed on the corrected sub-pixels in the feature pattern area to obtain the target screen data; when there is no feature pattern area in the initial screen according to the reordered screen data, the reordered screen data is directly used as the target screen data. It can be understood that in other embodiments, sub-pixel reordering may not be performed first. For example, sub-pixel reordering may be performed after grayscale transition correction, or the display panel may directly receive and apply the screen data without sub-pixel reordering.

[0128] In an embodiment of the present disclosure, obtaining the screen data may be obtaining the screen data of the initial screen. The screen data of this initial screen may be directly used to obtain the feature pattern area without going through the sub-pixel reordering process. It can be understood that when determining the corrected sub-pixels and reference sub-pixels, it is necessary to determine the corrected sub-pixels and reference sub-pixels according to the arrangement pattern of the sub-pixels on the display panel, rather than according to the sub-pixel arrangement structure in the initial screen data. This embodiment is applicable to the situation where the control component CTR does not need to perform sub-pixel reordering or performs sub-pixel reordering after grayscale transition correction. Of course, in some examples, sub-pixel reordering may also be performed after determining the corrected sub-pixels and reference sub-pixels and before performing grayscale transition correction on the corrected sub-pixels.

[0129] In another embodiment of the present disclosure, obtaining the picture data may be obtaining the reordered picture data. In this way, the sub-pixel arrangement structure in the reordered picture data is the same as that of the display panel, and the gray levels of the sub-pixels in the reordered picture data can be directly used as the gray levels of the corresponding sub-pixels on the display panel.

[0130] In one embodiment of the present disclosure, when obtaining the picture data, the picture data of the initial picture may be obtained; then, according to the arrangement structure of each sub-pixel SP in the liquid crystal display panel PNL, the positions of the gray levels of each sub-pixel SP in the picture data of the initial picture are adjusted to obtain the reordered picture data.

[0131] In one embodiment of the present disclosure, the data acquisition unit UA is configured to obtain the picture data of the initial picture, and reorder the arrangement order of the gray levels of at least some sub-pixels in the picture data of the initial picture according to the sub-pixel arrangement mode of the display panel to obtain the reordered picture data.

[0132] In one example, the data acquisition unit UA includes a data cache sub-unit UA1 and a sub-pixel reordering sub-unit UA2; the data cache sub-unit UA1 is configured to obtain the picture data of the initial picture;

[0133] The sub-pixel reordering sub-unit UA2 is configured to reorder the arrangement order of the gray levels of at least some sub-pixels in the picture data of the initial picture according to the sub-pixel arrangement mode of the display panel, so that the data in the data cache sub-unit UA1 is updated to the reordered picture data.

[0134] See Figure 12 , in the embodiment of the present disclosure, the feature pattern area includes at least one of a first feature pattern area, a second feature pattern area, and a third feature pattern area. In the Figure 12 example, three different pattern areas, namely the first feature pattern area, the second feature pattern area, and the third feature pattern area, are taken as the feature pattern areas for illustration. It can be understood that in other embodiments of the present disclosure, the feature pattern area does not include any one or two of the first feature pattern area, the second feature pattern area, and the third feature pattern area. Correspondingly, the modified sub-pixels include one or more of a first modified sub-pixel, a second modified sub-pixel, a third modified sub-pixel, a fourth modified sub-pixel, a fifth modified sub-pixel, etc. Among them, the first modified sub-pixel and the second modified sub-pixel are determined according to the first feature pattern area, the third modified sub-pixel is determined according to the second feature pattern area, and the fourth modified sub-pixel and the fifth modified sub-pixel are determined according to the third feature pattern area. In the embodiment of the present disclosure, the first feature pattern area, the second feature pattern area, and the third feature pattern area are determined according to the picture data before gray level transition correction.

[0135] It can be understood that the driving method and control component of the embodiments of the present disclosure can obtain a characteristic image area and perform grayscale transition correction for each frame of picture data. In this way, different picture data can obtain different characteristic image areas; of course, it is also possible that some or all of the characteristic image areas remain unchanged.

[0136] In some embodiments of the present disclosure, the first characteristic pattern area can be obtained and adjusted as the characteristic pattern area. At this time, the first characteristic pattern area can be obtained according to the picture data.

[0137] See Figures 14 - 16 , the first characteristic pattern area TAA includes a plurality of first characteristic pixel groups PA arranged in sequence along the column direction DV, and the first characteristic pixel group PA includes first characteristic pixels PA1, second characteristic pixels PA2, and third characteristic pixels PA3 that are adjacent to each other in the same row in sequence; wherein, the brightness difference between the first characteristic pixel PA1 and the second characteristic pixel PA2 is greater than or equal to the brightness threshold Lset; the brightness difference between the third characteristic pixel PA3 and the second characteristic pixel PA2 is greater than or equal to the brightness threshold Lset; all the first characteristic pixels PA1 are arranged in the same column.

[0138] When adjusting the first characteristic pattern area, according to the arrangement structure of the sub-pixels on the display panel, the sub-pixel SP of the first characteristic pixel PA1 close to the second characteristic pixel PA2 is used as the first correction sub-pixel SA1 for grayscale transition correction, and the sub-pixel SP of the third characteristic pixel PA3 close to the second characteristic pixel PA2 is used as the second correction sub-pixel SA2 for grayscale transition correction, so that Gx(SA1) is located between G(SA1) and G(SA10), and Gx(SA2) is located between G(SA2) and G(SA20); Gx(SA1) is the corrected grayscale of the first correction sub-pixel SA1, G(SA1) is the grayscale before correction of the first correction sub-pixel SA1, G(SA10) is the grayscale of the reference sub-pixel SA10 of the first correction sub-pixel, and the reference sub-pixel SA10 of the first correction sub-pixel is the sub-pixel SP that is the same color as the first correction sub-pixel SA1 and is located in the second characteristic pixel PA2 adjacent to the first correction sub-pixel SA1; Gx(SA2) is the corrected grayscale of the second correction sub-pixel SA2, G(SA2) is the grayscale before correction of the second correction sub-pixel SA2, G(SA20) is the grayscale of the reference sub-pixel SA20 of the second correction sub-pixel, and the reference sub-pixel SA20 of the second correction sub-pixel is the sub-pixel SP that is the same color as the second correction sub-pixel SA2 and is located in the second characteristic pixel PA2 adjacent to the second correction sub-pixel SA2.

[0139] When driving the liquid crystal display panel PNL, according to the corrected gray levels of the first corrected sub-pixel SA1 and the second corrected sub-pixel SA2.

[0140] In this embodiment, when there is a first feature pattern area TAA in the frame data, each second feature pixel PA2 in the first feature pattern area TAA forms a feature vertical line (a single-pixel line along the column direction), and the brightness difference between this feature vertical line and the patterns on both sides is relatively large; if the gray levels of some sub-pixels in the first feature pattern area TAA are not corrected, obvious jaggedness will appear on both side edges of the feature vertical line. In step S130 of the present disclosure, the gray levels of the first corrected sub-pixel SA1 and the second corrected sub-pixel SA2 can be corrected, so that the brightness difference between the sub-pixel SP adjacent to the second feature pixel PA2 on the display panel and the second feature pixel PA2 is reduced, and during this process, the gray levels of each of the second feature pixels PA2 remain unchanged. In this way, it is possible to eliminate the possible visible jaggedness on both sides of the second feature pixel PA2 while ensuring the normal display of the second feature pixel PA2, and improve the display effect of the feature vertical line. As a counterexample, if the gray levels of each second feature pixel PA2 itself are adjusted, for example, the gray levels of the sub-pixel SP adjacent to the first feature pixel PA1 in the second feature pixel PA2 and the sub-pixel SP adjacent to the third feature pixel PA3 in the second feature pixel PA2 are corrected, it will cause the feature vertical line formed by each second feature pixel PA2 to become narrower and less clear visually. For example, when each second feature pixel PA2 forms a white vertical line and each first feature pixel PA1 and third feature pixel PA3 form a black pattern, reducing the gray levels of the sub-pixels SP adjacent to the first feature pixel PA1 and third feature pixel PA3 in the second feature pixel PA2 will cause the brightness and width of the white vertical line to decrease, thereby reducing the display effect of the white vertical line. Of course, it can be understood that if there is no first feature pattern area TAA in the initial frame, the gray level transition correction of the first corrected sub-pixel SA1 and the second corrected sub-pixel SA2 will not be performed accordingly.

[0141] Optionally, the brightness difference between the feature vertical line in the first feature pattern area TAA and the patterns on both sides is relatively large. This difference can be that the feature vertical line is darker than the patterns on both sides in the row direction (see Figure 15 ), or the feature vertical line is brighter than the patterns on both sides in the row direction (see Figure 14 ), or the feature vertical line is brighter than one pattern and darker than the other pattern (see Figure 16 ). In any case, the sub-pixels in the sub-pixel column adjacent to the feature vertical line are used as the corrected sub-pixels, which can avoid poor display effects caused by the feature vertical line being too narrow or the brightness decreasing.

[0142] Optionally, the color of the feature vertical line may be the same as or different from the colors of the patterns on both sides. In one example, the colors on both sides of the feature vertical line may be the same, especially when the colors and gray levels of the pixels are the same. This makes the feature vertical line a vertical line in a solid-color pattern.

[0143] Optionally, the colors and gray levels of the respective pixels of the feature vertical line (i.e., the respective second feature pixels PA2) are the same. In other words, the feature vertical line may be a solid-color vertical line with the same brightness.

[0144] In one embodiment of the present disclosure, in the first feature pattern area TAA, the gray levels of the respective sub-pixels of the same feature pixel before correction are the same. In other words, each pixel in the first feature pattern area TAA displays a grayscale pattern, making the first feature pattern area TAA particularly suitable for processing black-and-white patterns.

[0145] It can be understood that the above adjustment method of the first feature pattern area is only one embodiment of the present disclosure. For example, in another embodiment, when it is specified that the gray levels of the respective sub-pixels of the first feature pixel, the gray levels of the respective sub-pixels of the second feature pixel, and the gray levels of the respective sub-pixels of the third feature pixel are the same, that is, when the first feature pattern area is specified as a grayscale pattern, when adjusting the first feature pattern area, it is also possible to make the reference sub-pixels of the first corrected sub-pixel and the reference sub-pixels of the second corrected sub-pixel be other sub-pixels. For example, it is possible to make the reference sub-pixel of the first corrected sub-pixel be any one or more sub-pixels in the second feature pixel adjacent to the first corrected sub-pixel, or be the sub-pixels in the second feature pixel and adjacent to the first corrected sub-pixel. For another example, it is possible to make the reference sub-pixel of the second corrected sub-pixel be any one or more sub-pixels in the second feature pixel adjacent to the second corrected sub-pixel, or be the sub-pixels in the second feature pixel and adjacent to the second corrected sub-pixel.

[0146] In one embodiment of the present disclosure, the number of the first feature pixel groups PA in the first feature pattern area TAA is greater than or equal to the first quantity threshold. In other words, if the number of pixels of the vertical line (the number of pixel rows occupied by the vertical line in the column direction) does not reach the first quantity threshold, it will not be determined whether the vertical line belongs to the first feature pattern area TAA. This is because the jagged feeling generated when the number of pixels of the vertical line is small is not obvious, so good display effects can be maintained without using gray-level transition correction. Optionally, the first quantity threshold can be determined according to prior detection, especially in combination with the actual usage scenario of the display device and the corresponding detection. Optionally, the first quantity threshold is a positive integer greater than or equal to 3, especially it can be a positive integer greater than or equal to 5; for example, it can be one of 5, 6, 7, 8, 9, 10.

[0147] In one embodiment of the present disclosure, the first quantity threshold can be obtained through testing. For example, in a preset environment, such as viewing a picture containing a vertical bright-dark boundary line at a preset distance (e.g., 0.5 meters) from the liquid crystal display panel PNL of the display panel and at a preset viewing angle (e.g., directly in front), by adjusting the first quantity threshold until the sawtooth of the vertical bright-dark boundary line disappears or the visibility is weakened to an acceptable level.

[0148] In some embodiments of the present disclosure, the feature pattern area includes a second feature pattern area. In other words, the second feature pattern area can be obtained and adjusted as the feature pattern area.

[0149] See Figure 17 , the second feature pattern area TAB includes a plurality of second feature pixel groups PB arranged in sequence along the column direction DV. Each second feature pixel group PB includes a fourth feature pixel PB1, a fifth feature pixel PB2, and a sixth feature pixel PB3 that are adjacent to each other in the same row in sequence. Among them, the brightness difference between the fourth feature pixel PB1 and the fifth feature pixel PB2 is greater than or equal to the brightness threshold Lset; the brightness difference between the sixth feature pixel PB3 and the fifth feature pixel PB2 is less than the brightness threshold Lset; all the fourth feature pixels PB1 are arranged in the same column.

[0150] When adjusting the second feature pattern area, according to the arrangement structure of the sub-pixels on the display panel, the sub-pixel SP of the fourth feature pixel PB1 that is close to the fifth feature pixel PB2 is used as the third correction sub-pixel SB1 for gray-scale transition correction; where Gx(SB1) is between G(SB1) and G(SB10); Gx(SB1) is the corrected gray-scale of the third correction sub-pixel SB1, G(SB1) is the gray-scale before correction of the third correction sub-pixel SB1, G(SB10) is the gray-scale of the reference sub-pixel SB10 of the third correction sub-pixel, and the reference sub-pixel SB10 of the third correction sub-pixel is the sub-pixel SP that is the same color as the third correction sub-pixel SB1 and is located in the adjacent fifth feature pixel PB2.

[0151] When driving the liquid crystal display panel PNL, the liquid crystal display panel PNL is driven according to the corrected gray-scale of the third correction sub-pixel SB1.

[0152] In this embodiment, when there is a second feature pattern area TAB in the screen data, there is a large brightness difference between the pixel column where the fifth feature pixel PB2 in the second feature pattern area TAB is located and the pixel column where the fourth feature pixel PB1 is located. This makes the line displayed by the pixel column where the fifth feature pixel PB2 is located have an obvious serrated feeling on the side close to the fourth feature pixel PB1. In this embodiment, by correcting the gray-scale transition of the third correction sub-pixel SB1, the brightness difference between the fourth feature pixel PB1 and the fifth feature pixel PB2 is reduced, and the smoothness of the line displayed by the pixel column where the fifth feature pixel PB2 is located is improved. The brightness difference between the fifth feature pixel PB2 and the sixth feature pixel PB3 is relatively small, so it will not cause a serrated feeling or the serrated feeling is very low. Therefore, there is no need to correct the gray-scale transition of the sub-pixels SP in the sixth feature pixel PB3.

[0153] In some examples, the display device is further configured to determine whether there is a second feature pattern area group; the second feature pattern area group is composed of two second feature pattern areas. Refer to Figure 18 , where one of the second feature pattern areas can be used as the selected second feature pattern area TAB1 and the other second feature pattern area as the auxiliary second feature pattern area TAB2. The fourth feature pixel PB1 of the selected second feature pattern area TAB1 is the fifth feature pixel PB2 of the auxiliary second feature pattern area TAB2, and the fifth feature pixel PB2 of the selected second feature pattern area TAB1 is the fourth feature pixel PB1 of the auxiliary second feature pattern area TAB2; in the selected second feature pattern area TAB1, the gray scale of the fourth feature pixel PB1 is greater than the gray scale of the fifth feature pixel PB2. Therefore, in the second feature pattern area group, the two second feature pattern areas share the same two columns of pixels and have the same length in the column direction.

[0154] When there is the second feature pattern area group, the third correction sub-pixel SB1 of the selected second feature pattern area TAB1 performs gray-scale transition correction and the third correction sub-pixel SB1 of the auxiliary second feature pattern area TAB2 does not perform gray-scale transition correction. In this way, the boundary vertical line between the color block patterns can be corrected to eliminate the serrated feeling of the boundary vertical line. When performing the correction, the gray scale of the sub-pixel closest to the side with a smaller brightness in the pixels on the side with a larger brightness is reduced. Exemplarily, in one final effect, at the boundary vertical line between a bright color block pattern and a dark color block pattern, the gray-scale transition correction is performed on a column of sub-pixels on the side of the bright color block pattern to weaken or eliminate the serrated feeling at the boundary vertical line between the bright color block pattern and the dark color block pattern.

[0155] In some examples, the transition correction unit is further configured to: determine whether there is a second feature pattern group; the second feature pattern group includes a selected second feature pattern area TAB1 and an auxiliary second feature pattern area TAB2, a fourth feature pixel PB1 of the selected second feature pattern area TAB1 is a fifth feature pixel PB2 of the auxiliary second feature pattern area TAB2, and a fifth feature pixel PB2 of the selected second feature pattern area TAB1 is a fourth feature pixel PB1 of the auxiliary second feature pattern area TAB2; in the selected second feature pattern area TAB1, the gray scale of the fourth feature pixel PB1 is greater than the gray scale of the fifth feature pixel PB2.

[0156] When there is the second feature pattern group, gray scale transition correction is performed on a third correction sub-pixel SB1 of the selected second feature pattern area TAB1, and gray scale transition correction is not performed on a third correction sub-pixel SB1 of the auxiliary second feature pattern area TAB2. In this way, the boundary vertical line between color block patterns can be corrected to eliminate the jagged feeling of the boundary vertical line. When performing the correction, the gray scale of the sub-pixel closest to the side with a smaller brightness among the pixels on the side with a larger brightness is reduced. Exemplarily, in one final effect, at the boundary vertical line between a bright color block pattern and a dark color block pattern, gray scale transition correction is performed on a column of sub-pixels on the side of the bright color block pattern to weaken or eliminate the jagged feeling at the boundary vertical line between the bright color block pattern and the dark color block pattern.

[0157] In some examples, in step S130, it is also possible to determine whether there is a second feature pattern group; the second feature pattern group includes a selected second feature pattern area TAB1 and an auxiliary second feature pattern area TAB2, a fourth feature pixel PB1 of the selected second feature pattern area TAB1 is a fifth feature pixel PB2 of the auxiliary second feature pattern area TAB2, and a fifth feature pixel PB2 of the selected second feature pattern area TAB1 is a fourth feature pixel PB1 of the auxiliary second feature pattern area TAB2; in the selected second feature pattern area TAB1, the gray scale of the fourth feature pixel PB1 is greater than the gray scale of the fifth feature pixel PB2.

[0158] When the second feature pattern block exists, the third correction sub-pixel SB1 of the selected second feature pattern area TAB1 performs gray-scale transition correction, and the third correction sub-pixel SB1 of the auxiliary second feature pattern area TAB2 does not perform gray-scale transition correction. In this way, the boundary vertical lines between the color block patterns can be corrected to eliminate the jagged feeling of the boundary vertical lines. When performing the correction, the gray scale of the sub-pixel closest to the side with a smaller brightness among the pixels on the side with a larger brightness is reduced. Exemplarily, in one final effect, at the boundary vertical line between a bright color block pattern and a dark color block pattern, gray-scale transition correction is performed on a column of sub-pixels on the side of the bright color block pattern to weaken or eliminate the jagged feeling at the boundary vertical line between the bright color block pattern and the dark color block pattern.

[0159] In an embodiment of the present disclosure, in the second feature pattern area TAB, the gray scales of the respective sub-pixels of the same pixel (feature pixel) before correction are the same; in other words, the pattern in the second feature pattern area TAB can be a grayscale pattern, such as a black-and-white pattern.

[0160] In an embodiment of the present disclosure, if the first feature pattern area TAA and the second feature pattern area TAB are both adjusted as feature pattern areas, then when obtaining the feature pattern areas, the first feature pattern area TAA and the second feature pattern area TAB can be obtained successively or simultaneously. For example, in one example, after obtaining the first feature pattern area TAA according to the reordered picture data, the second feature pattern area TAB is obtained from outside the first feature pattern area TAA. In another example, the first feature pattern area TAA and the second feature pattern area TAB can be obtained simultaneously from the reordered picture data.

[0161] It can be understood that the above adjustment method of the second feature pattern area is only one embodiment of the present disclosure. For example, in another embodiment, when it is specified that the gray scales of the respective sub-pixels of the fourth feature pixel are the same, the gray scales of the respective sub-pixels of the fifth feature pixel are the same, and the gray scales of the respective sub-pixels of the sixth feature pixel are the same, that is, when the second feature pattern area is specified as a grayscale pattern, when adjusting the second feature pattern area, the reference sub-pixel of the third correction sub-pixel can also be other sub-pixels. For example, the reference sub-pixel of the third correction sub-pixel can be any one or more sub-pixels located in the fifth feature pixel adjacent to the third correction sub-pixel, or the sub-pixels located in the fifth feature pixel and adjacent to the third correction sub-pixel.

[0162] In an implementation manner of the present disclosure, the number of the second feature pixel groups PB in the second feature pattern area TAB is greater than or equal to a second quantity threshold. In other words, if the number of pixels of a vertical line (the number of rows occupied by the vertical line in the column direction) does not reach the second quantity threshold, it will not be determined whether the vertical line belongs to the second feature pattern area TAB. This is because the jagged feeling generated when the number of pixels of the vertical line is small is not obvious, so a good display effect can be maintained without using gray-scale transition correction. Optionally, the second quantity threshold can be determined according to a pre-detection, especially in combination with the actual use scenario of the display device and the corresponding detection. Optionally, the second quantity threshold is a positive integer greater than or equal to 3, especially a positive integer greater than or equal to 5; for example, it can be one of 5, 6, 7, 8, 9, 10.

[0163] In an example, the second quantity threshold is the same as the first quantity threshold, for example, both are 5.

[0164] In some implementation manners of the present disclosure, the feature pattern area may include a third feature pattern area. In other words, the third feature pattern area can be obtained and adjusted as the feature pattern area.

[0165] See Figures 19 - 22 , the third feature pattern area TAC includes a first sub-pixel group TPA, a second sub-pixel group TPB, and a third sub-pixel group TPC that are adjacent to each other in sequence along the row direction DH; the second sub-pixel group TPB includes 3 sub-pixels SP that are adjacent to each other in sequence along the row direction DH; the first sub-pixel group TPA and the third sub-pixel group TPC each include a plurality of sub-pixels SP that are adjacent to each other in sequence along the row direction DH; in the first sub-pixel group TPA, the gray levels of the sub-pixels SP of the same color are the same, and the number of any one kind of sub-pixels SP of the same color is N1; in the third sub-pixel group TPC, the gray levels of the sub-pixels SP of the same color are the same, and the number of any one kind of sub-pixels SP of the same color is N2; both N1 and N2 are positive integers from 1 to 1000; the difference between the brightness of the second sub-pixel group TPB and the brightness of the pixels in the first sub-pixel group TPA is greater than or equal to the brightness threshold Lset; the difference between the brightness of the second sub-pixel group TPB and the brightness of the pixels in the third sub-pixel group TPC is greater than or equal to the brightness threshold Lset.

[0166] In some other embodiments of the present disclosure, the third feature pattern region TAC includes a first sub-pixel group TPA, a second sub-pixel group TPB, and a third sub-pixel group TPC that are adjacent to each other in sequence along the row direction DH. The first sub-pixel group TPA includes K1 sub-pixels SP that are adjacent to each other in sequence along the row direction DH; in the first sub-pixel group TPA, the gray levels of all the sub-pixels SP are the same; K1 is a positive integer from 3 to 3000. The third sub-pixel group TPC includes K2 sub-pixels SP that are adjacent to each other in sequence along the row direction DH; in the third sub-pixel group TPC, the gray levels of all the sub-pixels SP are the same; K2 is a positive integer from 3 to 3000. The difference in brightness between the second sub-pixel group TPB and the pixels in the first sub-pixel group TPA is greater than or equal to the brightness threshold Lset; the difference in brightness between the second sub-pixel group TPB and the pixels in the third sub-pixel group TPC is greater than or equal to the brightness threshold Lset. In this case, the first sub-pixel group TPA and the third sub-pixel group TPC display gray-scale patterns. For example, in this case, the gray levels of all the sub-pixels in the second sub-pixel group TPB are the same.

[0167] Optionally, both K1 and K2 are integers not exceeding 300, for example, they can be integers not exceeding 150, and in particular, they can be integers not exceeding 60. In one embodiment of the present disclosure, both K1 and K2 are positive integers from 9 to 30. When the values of K1 and K2 are too small, two intersecting curves or oblique lines may visually present a thickening effect near the intersection position, and the visual perception is not ideal. When the values of K1 and K2 are too large, the number of patterns that can be adjusted will be too small, resulting in a reduction in the overall improvement effect, and it will also cause the omission of patterns that can be adjusted. It can be understood that the three sub-pixels in the second sub-pixel group TPB can belong to the same pixel on the display panel or two adjacent pixels on the display panel.

[0168] When adjusting the third feature pattern region, refer to Figures 19 - 22, according to the arrangement structure of the sub-pixels on the display panel, the sub-pixel SP in the first sub-pixel group TPA close to the second sub-pixel group TPB is used as the fourth correction sub-pixel SC1 for gray-scale transition correction, and the sub-pixel SP in the third sub-pixel group TPC close to the second sub-pixel group TPB is used as the fifth correction sub-pixel SC2 for gray-scale transition correction; wherein, Gx(SC1) is between G(SC1) and G(SC10); the Gx(SC1) is the corrected gray-scale of the fourth correction sub-pixel SC1, the G(SC1) is the gray-scale before correction of the fourth correction sub-pixel SC1, the G(SC10) is the gray-scale of the reference sub-pixel SC10 of the fourth correction sub-pixel, and the reference sub-pixel SC10 of the fourth correction sub-pixel is the sub-pixel SP of the same color as the fourth correction sub-pixel SC1 in the second sub-pixel group TPB; Gx(SC2) is between G(SC2) and G(SC20); the Gx(SC2) is the corrected gray-scale of the fifth correction sub-pixel SC2, the G(SC2) is the gray-scale before correction of the fifth correction sub-pixel SC2, the G(SC20) is the gray-scale of the reference sub-pixel SC20 of the fifth correction sub-pixel, and the reference sub-pixel SC20 of the fifth correction sub-pixel is the sub-pixel SP of the same color as the fifth correction sub-pixel SC2 in the second sub-pixel group TPB.

[0169] When driving the liquid crystal display panel PNL, drive the liquid crystal display panel PNL according to the corrected gray-scales of the fourth correction sub-pixel SC1 and the fifth correction sub-pixel SC2.

[0170] In some examples, the display device is configured that when the feature pattern area includes the first feature pattern area and the third feature pattern area, if a pixel satisfies both the first feature pattern area and the third feature pattern area, then the pixel belongs to the first feature pattern area.

[0171] In some examples, the feature pattern area acquisition unit is further configured that when the feature pattern area includes the first feature pattern area and the third feature pattern area, if a pixel satisfies both the first feature pattern area and the third feature pattern area, then the pixel belongs to the first feature pattern area.

[0172] In some examples, in step S120, when the feature pattern area includes the first feature pattern area and the third feature pattern area, if a pixel satisfies both the first feature pattern area and the third feature pattern area, then the pixel belongs to the first feature pattern area.

[0173] In one example, the first feature pattern area TAA can be obtained first, and then the third feature pattern area TAC can be obtained, and the second sub-pixel group TPB is made not to intersect with the first feature pattern area TAA. In this way, repeated gray-scale transition correction for the same pixel or sub-pixel can be avoided. For example, when a pixel can be divided into the first feature pattern area TAA, the pixel is preferentially divided into the first feature pattern area TAA, thereby ensuring that the feature vertical lines in the initial image can be fully obtained.

[0174] It can be understood that the first feature pattern area TAA includes a plurality of first feature pixel groups PA adjacent to each other in the same column. That is, gray-scale transition correction according to the first feature pattern area TAA is the correction of multiple rows of pixels. The third feature pattern area TAC includes a plurality of sub-pixels adjacent to each other in the same row; gray-scale transition correction according to the third feature pattern area TAC is the pixel transition correction of the dot pattern, and the corrected sub-pixels are in the same row.

[0175] In this embodiment, when the third feature pattern area TAC is found, the second sub-pixel group TPB for displaying the dot pattern can be expanded by one sub-pixel to each side (in the row direction) to display the dot pattern, and the expanded sub-pixels are used as corrected sub-pixels for gray-scale transition correction. For example, the first sub-pixel group TPA and the third sub-pixel group TPC on both sides of the second sub-pixel group TPB can both be solid-color patterns. Therefore, borrowing one edge sub-pixel will not reduce the display effect, but will make the display of the dot pattern clearer. When the dot patterns displayed by some of the second sub-pixel groups TPB are connected to form a diagonal line or a curve, this embodiment can also achieve compensation for the edges of the diagonal line or the curve, eliminating or weakening the jagged feeling of the edges of these diagonal lines or curves. Moreover, while increasing the smoothness of the curve or diagonal line, the diagonal line or curve can be widened, thereby increasing the brightness of the diagonal line or curve.

[0176] In some embodiments of the present disclosure, a solid-color pattern means that the colors and brightnesses of the individual pixels forming the pattern are the same. Specifically, the gray-scale data of the pixels forming the pattern are the same. In a solid-color pattern, the gray scales of all the red sub-pixels are the same, the gray scales of all the green sub-pixels are the same, and the gray scales of all the blue sub-pixels are the same. The solid-color pattern can be a solid-color pattern with single-sub-pixel emission, such as a red pattern, a green pattern, or a blue pattern, or a solid-color pattern with multi-sub-pixel emission, such as a purple pattern, a magenta pattern, a cyan pattern, a white pattern, a gray pattern, or a black pattern in which all sub-pixels do not emit light.

[0177] In some other embodiments of the present disclosure, the solid color pattern may also mean that the colors and brightness of the respective pixels forming the pattern are similar. The criterion for "similar" is that for the image directly displayed on the initial screen by the human eye, there is no obvious transition between different parts. Thus, the first sub-pixel group TPA may include a plurality of similar pixels, and the data (color and gray scale) of each pixel is similar; among them, for the image directly displayed on the initial screen by the human eye, there is no obvious transition between different parts of the first sub-pixel group. The third sub-pixel group TPC may include a plurality of similar pixels, and the data (color and gray scale) of each pixel is similar; among them, for the image directly displayed on the initial screen by the human eye, there is no obvious transition between different parts of the third sub-pixel group. Thus, without departing from the main purpose and intention of the protection of the present disclosure, the applicable scope of the first sub-pixel group and the third sub-pixel group can be expanded, and then the applicable scope of the third characteristic pattern area can be expanded, having a better display effect.

[0178] It can be understood that the above adjustment method of the third characteristic pattern area is only one of the embodiments of the present disclosure. For example, in another embodiment, when the gray scales of the respective sub-pixels of the second sub-pixel group defining the third characteristic pattern area are the same, the reference sub-pixel of the fourth correction sub-pixel is not necessarily the sub-pixel of the same color as the fourth correction sub-pixel in the second sub-pixel group. For example, the reference sub-pixel of the fourth correction sub-pixel may be any one or more sub-pixels located in the second sub-pixel group, or a sub-pixel located in the second sub-pixel group and adjacent to the fourth correction sub-pixel. For another example, when the gray scales of the respective sub-pixels of the second sub-pixel group defining the third characteristic pattern area are the same, the reference sub-pixel of the fifth correction sub-pixel is not necessarily the sub-pixel of the same color as the fifth correction sub-pixel in the second sub-pixel group. For example, the reference sub-pixel of the fifth correction sub-pixel may be any one or more sub-pixels located in the second sub-pixel group, or a sub-pixel located in the second sub-pixel group and adjacent to the fifth correction sub-pixel.

[0179] It can be understood that the adjustment method of the above third characteristic pattern area is only one implementation mode of the present disclosure. In this implementation mode, it is defined that the second sub-image group is composed of 3 sub-pixels. In other implementation modes of the present disclosure, the second sub-pixel group can also be composed of more sub-pixels. For example, in another implementation mode, the second sub-pixel group includes 3 to 5 sub-pixels, and the gray levels of each sub-pixel are the same. At this time, it is not necessarily required that the number of sub-pixels in any two second sub-pixel groups is the same; for example, some second sub-pixel groups can include 3 sub-pixels, some second sub-pixel groups can include 4 sub-pixels, and some second sub-pixel groups can include 5 sub-pixels. In this implementation mode, the reference sub-pixel of the fourth correction sub-pixel can be any one or more sub-pixels located in the second sub-pixel group, or a sub-pixel located in the second sub-pixel group and adjacent to the fourth correction sub-pixel. The reference sub-pixel of the fifth correction sub-pixel can be any one or more sub-pixels located in the second sub-pixel group, or a sub-pixel located in the second sub-pixel group and adjacent to the fifth correction sub-pixel.

[0180] Of course, based on the inventive concept and means of the present disclosure, in other implementation modes of the present disclosure, other types of modifications can also be made to the definition and adjustment method of the third characteristic pattern area, so as to achieve a similar effect. For example, the second sub-pixel group TPB can also have more than 3 sub-pixels, for example, it can have 4, 5 or 6 sub-pixels. For example, the second sub-pixel group TPB can have 3 - 6 sub-pixels. For example, the second sub-pixel group TPB can have 3 - 5 sub-pixels. In this way, only when the second sub-pixel group TPB is greater than or equal to 1 pixel width and less than 2 pixel widths, the brightness of at least some sub-pixels in the characteristic pattern area is adjusted, and a better improvement effect is achieved. For example, the lines processed in this way have an ideal visual effect.

[0181] Figure 20 The case where the second sub-pixel group TPB has four sub-pixels is illustrated; Figure 21 The case where the second sub-pixel group TPB has five sub-pixels is illustrated; Figure 22An example of a case where the second sub-pixel group TPB has six sub-pixels is illustrated. In one example, when the number of sub-pixels in the second sub-pixel group TPB exceeds three, the average pixel luminance of the second sub-pixel group TPB can be used as the luminance of the second sub-pixel group TPB. For example, (3 / M)*∑Lsp can be used as the luminance of the second sub-pixel group TPB, where M represents the number of sub-pixels in the second sub-pixel group TPB, and ∑Lsp represents the sum of the luminances of each sub-pixel in the second sub-pixel group TPB. In this way, the embodiments of the present disclosure can perform gray-scale transition correction on a wider dot pattern, further improving the display effect. Especially when the display panel displays a straight line with a small slope, some points of the straight line may need to be displayed through 4 to 6 sub-pixels to present continuously and clearly. This example can perform gray-scale transition correction on these dot patterns to eliminate the possible jagged feeling of the straight line.

[0182] In another embodiment of the present disclosure, the second sub-pixel group TPB has no less than three sub-pixels. When there are two or more sub-pixels in the second sub-pixel group TPB that have the same color as the fourth correction sub-pixel SC1, the reference sub-pixel of the fourth correction sub-pixel SC1 can be the sub-pixel in the second sub-pixel group TPB that has the same color as the fourth correction sub-pixel SC1 and is closest to the fourth correction sub-pixel SC1. Correspondingly, when there are two or more sub-pixels in the second sub-pixel group TPB that have the same color as the fifth correction sub-pixel SC2, the reference sub-pixel of the fifth correction sub-pixel SC2 can be the sub-pixel in the second sub-pixel group TPB that has the same color as the fifth correction sub-pixel SC2 and is closest to the fifth correction sub-pixel SC2.

[0183] In another embodiment of the present disclosure, the second sub-pixel group TPB has no less than 3 sub-pixels. When there are two or more sub-pixels in the second sub-pixel group TPB that have the same color as the fourth correction sub-pixel SC1, the reference sub-pixel of the fourth correction sub-pixel SC1 can be any one of the sub-pixels in the second sub-pixel group TPB that have the same color as the fourth correction sub-pixel SC1. Correspondingly, when there are two or more sub-pixels in the second sub-pixel group TPB that have the same color as the fifth correction sub-pixel SC2, the reference sub-pixel of the fifth correction sub-pixel SC2 can be any one of the sub-pixels in the second sub-pixel group TPB that have the same color as the fifth correction sub-pixel SC2. For example, when there are two or more sub-pixels in the second sub-pixel group TPB that have the same color as the fourth correction sub-pixel SC1, and the gray levels of the two or more sub-pixels that have the same color as the fourth correction sub-pixel SC1 are the same, the reference sub-pixel of the fourth correction sub-pixel SC1 can be any one or more of the sub-pixels in the second sub-pixel group TPB that have the same color as the fourth correction sub-pixel SC1. For example, when there are two or more sub-pixels in the second sub-pixel group TPB that have the same color as the fifth correction sub-pixel SC2, and the gray levels of the two or more sub-pixels that have the same color as the fifth correction sub-pixel SC2 are the same, the reference sub-pixel of the fifth correction sub-pixel SC2 can be any one or more of the sub-pixels in the second sub-pixel group TPB that have the same color as the fifth correction sub-pixel SC2.

[0184] In another embodiment of the present disclosure, the second sub-pixel group TPB has no less than 3 sub-pixels. When there are two or more sub-pixels in the second sub-pixel group TPB that have the same color as the fourth correction sub-pixel SC1, the gray level of the reference sub-pixel of the fourth correction sub-pixel SC1 can be the average of the gray levels of the respective sub-pixels in the second sub-pixel group TPB that have the same color as the fourth correction sub-pixel SC1. At this time, the reference sub-pixel of the fourth correction sub-pixel SC1 is a virtual sub-pixel rather than a physical sub-pixel, and the gray level of the virtual sub-pixel is the average of the gray levels of the sub-pixels of the same color in the second sub-pixel group TPB. Correspondingly, when there are two or more sub-pixels in the second sub-pixel group TPB that have the same color as the fifth correction sub-pixel SC2, the gray level of the reference sub-pixel of the fifth correction sub-pixel SC2 can be the average of the gray levels of the respective sub-pixels in the second sub-pixel group TPB that have the same color as the fifth correction sub-pixel SC2. At this time, the reference sub-pixel of the fifth correction sub-pixel SC2 is a virtual sub-pixel rather than a physical sub-pixel, and the gray level of the virtual sub-pixel is the average of the gray levels of the sub-pixels of the same color in the second sub-pixel group TPB.

[0185] In another embodiment of the present disclosure, the second sub-pixel group TPB has no less than 3 sub-pixels. When there are two or more sub-pixels in the second sub-pixel group TPB with the same color as the fourth corrected sub-pixel SC1, the luminance of the reference sub-pixel of the fourth corrected sub-pixel SC1 can be the average of the luminances of the sub-pixels with the same color as the fourth corrected sub-pixel SC1 in the second sub-pixel group TPB. At this time, the reference sub-pixel of the fourth corrected sub-pixel SC1 is a virtual sub-pixel rather than a physical sub-pixel, the luminance of the virtual sub-pixel is the average of the luminances of the sub-pixels with the same color in the second sub-pixel group TPB, and the gray level of the virtual sub-pixel is the gray level corresponding to its luminance. In other words, the luminance corresponding to the gray level of the reference sub-pixel of the fourth corrected sub-pixel SC1 is the average of the luminances of the sub-pixels with the same color in the second sub-pixel group TPB. Correspondingly, when there are two or more sub-pixels in the second sub-pixel group TPB with the same color as the fifth corrected sub-pixel SC2, the luminance of the reference sub-pixel of the fifth corrected sub-pixel SC2 can be the average of the luminances of the sub-pixels with the same color as the fifth corrected sub-pixel SC2 in the second sub-pixel group TPB. At this time, the reference sub-pixel of the fifth corrected sub-pixel SC2 is a virtual sub-pixel rather than a physical sub-pixel, the luminance of the virtual sub-pixel is the average of the luminances of the sub-pixels with the same color in the second sub-pixel group TPB, and the gray level of the virtual sub-pixel is the gray level corresponding to its luminance. In other words, the luminance corresponding to the gray level of the reference sub-pixel of the fifth corrected sub-pixel SC2 is the average of the luminances of the sub-pixels with the same color in the second sub-pixel group TPB. It can be understood that in the embodiment of the present disclosure, the luminance of the pixels in the sub-pixel group is the average pixel luminance in the sub-pixel group, rather than the sum of the luminances of the individual sub-pixels in the sub-pixel group.

[0186] In one embodiment of the present disclosure, in the first sub-pixel group TPA, the pre-correction gray levels of the sub-pixels of the same pixel are the same. In other words, the pixels in the first sub-pixel group TPA can be gray-scale pixels.

[0187] In one embodiment of the present disclosure, in the third sub-pixel group TPC, the pre-correction gray levels of the sub-pixels of the same pixel are the same. In other words, the pixels in the third sub-pixel group TPC can be gray-scale pixels.

[0188] Optionally, multiple third feature pattern regions TAC may be adjacent to each other in sequence along the column direction DV, and two adjacent third feature pattern regions TAC among the multiple third feature pattern regions TAC are arranged staggeredly. The staggered arrangement of two adjacent third feature pattern regions TAC can be understood as: two adjacent third feature pattern regions TAC are located in adjacent rows, and only some sub-pixels are located in the same pixel column. In this way, these third feature pattern regions TAC can form a diagonal line or a curve. By correcting the gray-scale transition of the corrected sub-pixels in each third feature pattern region TAC in the embodiment of the present disclosure, the jaggedness at the edge of the diagonal line or the curve can be weakened or eliminated.

[0189] In the embodiment of the present disclosure, by setting N1 and N2, interference between different patterns can be avoided. By setting reasonable sizes of N1 and N2, while improving the display effect of dot patterns, diagonal lines or curves formed by dot patterns, no new abnormalities are introduced. Both N1 and N2 are integers not exceeding 100, for example, they can be integers not exceeding 50, especially they can be integers not exceeding 20. In an embodiment of the present disclosure, both N1 and N2 are positive integers from 3 to 10. When the values of N1 and N2 are too small, two intersecting curves or diagonal lines may visually present a thickened effect near the intersection position, and the visual perception is not ideal. When the values of N1 and N2 are too large, the number of patterns that can be adjusted will be too small, resulting in a reduction in the overall improvement effect, and the patterns that can be adjusted will be missed. Figure 9 Illustrates the optimization effect of this embodiment on diagonal lines and curves. According to Figure 9 It can be seen that by adopting the embodiment of the present disclosure to adjust the third feature pattern region, the diagonal line and the curve can both become smooth and have no obvious jaggedness.

[0190] Optionally, N1 and N2 may be the same or different. In one example, both N1 and N2 are 5.

[0191] In the embodiment of the present disclosure, after obtaining the feature pattern region, the corrected gray scale of each corrected sub-pixel can be determined according to the feature pattern region. For example, after obtaining the first feature pattern region TAA, the corrected gray scales of the first corrected sub-pixel SA1 and the second corrected sub-pixel SA2 can be determined; after obtaining the second feature pattern region TAB, the corrected gray scale of the third corrected sub-pixel SB1 can be determined; after obtaining the third feature pattern region TAC, the corrected gray scales of the fourth corrected sub-pixel SC1 and the fifth corrected sub-pixel SC2 can be determined. Specifically, the corrected gray scale of the corrected sub-pixel is between the pre-correction gray scale of the corrected sub-pixel and the gray scale of the reference sub-pixel of the corrected sub-pixel. For example, the corrected gray scale of the corrected sub-pixel is determined according to the pre-correction gray scale of the corrected sub-pixel and the gray scale of the reference sub-pixel of the corrected sub-pixel according to a predetermined weighting method.

[0192] Optionally, when determining the corrected gray level of the corrected sub-pixel, Gx = round[G(L)+β*(G(H)-G(L))] can be used. Here, Gx is the corrected gray level of the corrected sub-pixel, G(L) is the smaller gray level among the gray level before correction of the corrected sub-pixel and the gray level of the reference sub-pixel of the corrected sub-pixel, G(H) is the larger gray level among the gray level before correction of the corrected sub-pixel and the gray level of the reference sub-pixel of the corrected sub-pixel; β is the gray level transition coefficient, which is greater than 0 and less than 1, especially between 0.1 and 0.9. Further, in the embodiments of the present disclosure, the gray level transition coefficients of sub-pixels of different colors are different. For example, the gray level transition coefficient can be determined according to the sensitivity of the human eye to light of different colors; the more sensitive the human eye is to light of a certain color, the lower the gray level transition coefficient of the sub-pixel of that color can be. In this way, adjacent sub-pixels in the corrected sub-pixel column are corrected for gray level transition using different gray level transition coefficients, which can make the effects presented between the corrected sub-pixels more uniform to the human eye, eliminating the jagged feeling caused by the large brightness difference between the corrected sub-pixels due to the different sensitivities of the human eye to different colors. For example, the sub-pixel SP includes a red sub-pixel SPR, a green sub-pixel SPG, and a blue sub-pixel SPB; the gray level transition coefficients of the red sub-pixel SPR, the green sub-pixel SPG, and the blue sub-pixel SPB decrease in sequence.

[0193] In one embodiment, when the red sub-pixel SPR is the corrected sub-pixel, the corrected gray level Gx(SPR) of the corrected sub-pixel is round[G(RL)+x*(G(RH)-G(RL))]; G(RH) is the larger gray level among the gray level before correction of the corrected sub-pixel and the reference sub-pixel of the corrected sub-pixel, G(RL) is the smaller gray level among the gray level before correction of the corrected sub-pixel and the gray level of the reference sub-pixel of the corrected sub-pixel; round() represents rounding to the nearest integer; x is the gray level transition coefficient of the red sub-pixel SPR.

[0194] When the green sub-pixel SPG is the corrected sub-pixel, the corrected gray level Gx(SPG) of the corrected sub-pixel is round[G(GL)+y*(G(GH)-G(GL))]; G(GH) is the larger gray level among the gray level before correction of the corrected sub-pixel and the reference sub-pixel of the corrected sub-pixel, G(GL) is the smaller gray level among the gray level before correction of the corrected sub-pixel and the gray level of the reference sub-pixel of the corrected sub-pixel; y is the gray level transition coefficient of the green sub-pixel SPG.

[0195] When the blue sub-pixel SPB is a corrected sub-pixel, the corrected gray level Gx(SPB) of the corrected sub-pixel is round[G(BL)+z*(G(BH)-G(BL))]; G(BH) is the larger gray level between the gray level before correction of the corrected sub-pixel and the reference sub-pixel of the corrected sub-pixel, and G(BL) is the smaller gray level between the gray level before correction of the corrected sub-pixel and the gray level of the reference sub-pixel of the corrected sub-pixel; z is the gray level transition coefficient of the blue sub-pixel SPB.

[0196] Further, 0.1≤z<y<x≤0.9.

[0197] In an embodiment of the present disclosure, there may be a large difference between the gray level transition coefficients of different color sub-pixels SP, for example, the difference is greater than or equal to 0.2, so as to fully compensate for the difference in the sensitivity of the human eye to different color lights. In one example, y - z>0.2; x - y>0.2.

[0198] In an embodiment of the present disclosure, 0.6≤x≤0.9; 0.35≤y≤0.65; 0.15≤z≤0.45. Exemplarily, x = 0.75; y = 0.50; z = 0.25.

[0199] In an embodiment of the present disclosure, the brightness threshold is 50 nits; the first quantity threshold is 5, the second quantity threshold is 5; N1 is 5, N2 is 5; the brightness of the pixel refers to the rated maximum brightness of the pixel at the maximum brightness of the display panel. When performing gray level transition correction on the corrected sub-pixel, the gray level transition coefficient of the red sub-pixel is 0.75, the gray level transition coefficient of the green sub-pixel is 0.5, and the gray level transition coefficient of the blue sub-pixel is 0.25.

[0200] In an embodiment of the present disclosure, the brightness threshold Lset can be obtained through testing. For example, in a preset environment, such as viewing a picture containing a feature pattern area at a preset distance (such as 0.5 meters) from the display panel PNL and at a preset viewing angle (such as directly in front), by adjusting the brightness threshold Lset so that the sawtooth of the bright-dark boundary vertical line disappears or the visibility is weakened to an acceptable level.

[0201] In one example, the brightness threshold Lset can be between 50 and 1000 nits, for example, it can be 50 nits. According to the usage scenario of the display panel and the requirements for quality, the brightness threshold of the display device can be determined through testing.

[0202] Of course, in other embodiments of the present disclosure, the brightness threshold can also be expressed as a gray level threshold, or other parameter thresholds related to the brightness threshold, as long as the brightness threshold can be directly or indirectly inferred.

[0203] In some embodiments of the present disclosure, there is a corresponding relationship between the brightness of a pixel and the gray level. Therefore, the brightness of each pixel can be determined according to the gray level data of the pixel, and then whether the brightness difference between two adjacent pixels is greater than or equal to the brightness threshold Lset can be determined according to the brightness of the pixels. In the embodiments of the present disclosure, the brightness of each sub-pixel of a pixel can be determined according to the gray level of each sub-pixel; the sum of the brightnesses of each sub-pixel is the brightness of the pixel. In one example, the brightness of a sub-pixel can be determined according to the gray level of the sub-pixel through a gamma curve.

[0204] In some other embodiments of the present disclosure, the brightness difference between two pixels may not be the brightness difference between the actual brightnesses of the two pixels, but may also be the difference in the theoretical maximum brightnesses of the two pixels, so as to reduce the computational complexity of the driving algorithm. For example, the theoretical maximum brightness of a pixel can be determined according to the rated maximum brightness of the display panel and the gray level data of the pixel, without considering whether the display panel displays the picture at the rated maximum brightness; in such a case, the theoretical maximum brightness difference between two pixels, that is, the brightness threshold Lset' can be set between 40 nits and 60 nits, or set between 50 and 1000 nits, and can be 50 nits for example. The control component CTR can pre-store the gamma curve GAmax at the rated maximum brightness; after obtaining the gray levels of each sub-pixel of the pixel, the theoretical maximum brightness of the sub-pixel can be determined according to the gray level of the sub-pixel and the gamma curve GAmax, and the theoretical maximum brightness of the pixel can be obtained according to the sum of the theoretical maximum brightnesses of each sub-pixel. Exemplarily, the rated maximum brightness of the display panel is between 300 and 1000 nits.

[0205] For example, a pixel includes three sub-pixels such as a red sub-pixel, a green sub-pixel, and a blue sub-pixel. When obtaining the gray level data of the pixel, the gray level of the red sub-pixel, the gray level of the green sub-pixel, and the gray level of the blue sub-pixel of the pixel can be obtained; then, according to the gray level of the red sub-pixel and the gamma curve of the red sub-pixel at the rated maximum brightness, the theoretical maximum brightness of the red sub-pixel is determined; according to the gray level of the green sub-pixel and the gamma curve of the green sub-pixel at the rated maximum brightness, the theoretical maximum brightness of the green sub-pixel is determined; according to the gray level of the blue sub-pixel and the gamma curve of the blue sub-pixel at the rated maximum brightness, the theoretical maximum brightness of the blue sub-pixel is determined. Then, the sum of the theoretical maximum brightnesses of the red sub-pixel, the green sub-pixel, and the blue sub-pixel is the theoretical maximum brightness of the pixel.

[0206] Of course, in other embodiments of the present disclosure, other methods can also be used to determine the brightness of a pixel (the brightness can be the actual brightness, or can be the theoretical maximum brightness, or can be other brightness related to the gray level).

[0207] In an embodiment of the present disclosure, the control component CTR may include an SOC (system-on-chip) board and a BCON (backlight control) board.

Further, when the display device is a liquid crystal display device, the SOC chip may generate synchronous picture data and synchronous dimming data according to the picture data. The synchronous backlight data is used to be sent to the liquid crystal display panel PNL for displaying a picture, and the synchronous dimming data is used to be sent to the MCU of the BCON board for controlling the duty ratio of each light zone of the BLU. Optionally, the SOC chip may generate synchronous dimming data and synchronous picture data according to the picture data to be displayed.

The SOC chip may receive initial picture data and perform processing such as sub-pixel reordering, transition zone determination, and transition zone correction on the initial picture data. Further, when the display device is a liquid crystal display device, the SOC chip may generate synchronous picture data and synchronous dimming data according to the picture data. The synchronous backlight data is used to be sent to the PNL for displaying a picture, and the synchronous dimming data is used to be sent to the MCU of the BCON board for controlling the duty ratio of each light zone of the BLU.

The synchronous dimming data generated by the FPGA can be directly sent to the backlight driving unit LEDD, and the backlight driving unit LEDD sends the duty cycle data of each light zone to the microchip MIC connected to each light zone according to the dimming data. In this way, it is possible to avoid the out-of-sync response between the display panel PNL and the backlight module BLU caused by the MCU forwarding the synchronous dimming data.

[0211] In one example, a power supply module PM, a power management unit PMIC, and a gamma voltage unit GMIC may also be provided on the circuit board of the FPGA board. The power supply module PM is used to connect to an external power supply and supply power to the power management unit PMIC and the backlight driving unit LEDD. The power management unit PMIC is configured to supply various different power supply voltages to the liquid crystal display panel PNL and supply power to the gamma voltage unit GMIC. The gamma voltage unit GMIC is configured to supply a common voltage VCOM and gamma binding point voltages VGamma corresponding to the gray levels of each gamma binding point to the liquid crystal display panel PNL. The power of the FPGA comes from the power supply module PM or the power management unit PMIC. In this way, the integrated board of the present disclosure can at least implement the functions of the screen driving board, the voltage board, and the conversion board in the related art, which can reduce the number of boards in the control component, thereby improving the integration degree of the control component and the assembly efficiency of the display device.

For example, multiple light zones LEDA controlled by cascaded microchips MIC in sequence are provided. Optionally, the panel port and the backlight port may be pads arranged in sequence or connectors for plugging, or other feasible structures.

[0213] In one example, a communication module is further provided on the circuit board of the FPGA board.

The communication module includes at least one video signal port and a signal conversion unit TRU; the video signal port is configured to receive a video signal and forward it to the signal conversion unit TRU; the signal conversion unit TRU is configured to transcode the video signal into initial picture data and forward the initial picture data to the FPGA.

[0214] Optionally, the signal conversion unit TRU can forward the picture data to the FPGA in the form of a TTL signal. For example, it can be forwarded in the form of a 24-channel TTL signal. It can be understood that in other examples of the present disclosure, the signal conversion unit TRU can also use other signals to forward the picture data, such as forwarding the picture data through an SPI signal, an LVDS signal, or a Mini LVDS signal.

[0215] Optionally, the video signal port is selected from one or more of an HDMI port, a DVI port, a VGA port, and a DP port. In Figure 23 the example, an HDMI port and a DVI port are provided on the FPGA board.

[0216] Optionally, the communication module may further include a serial communication port to enable the FPGA board to communicate with external devices. Further, the serial communication port may include a serial input port RSIN and a serial output port RSOUT. The serial input port RSIN can receive an external communication signal, for example, it is configured to receive an external control signal and transmit it to the FPGA; the serial output port RSOUT is used to send an external communication signal, for example, it is configured to send out the signal generated by the FPGA.

[0217] Optionally, the serial input port RSIN can forward the communication signal to the FPGA, and the FPGA responds to the communication signal. For example, a debugging device can send a debugging signal (as a kind of communication signal) to the FPGA through the serial input port RSIN, and the FPGA responds to the debugging signal to adjust the display state of the display device, such as adjusting the color temperature of the picture, adjusting the resolution, and displaying a debugging interface, etc. The serial output port RSOUT can receive the communication signal sent by the FPGA and forward it outward.
