Description

Flip chip space pixel arrangement structure, pixel multiplexing method, system, device and storage medium

Technical Field

The present disclosure relates to the field of display technologies, and in particular, to a flip chip spatial pixel arrangement structure, a pixel multiplexing method, a system, an apparatus, and a storage medium.

Background

Among flat panel display technologies, micro (mini) inorganic Light Emitting Diode (LED) displays are considered to be a fourth generation display technology following LCD displays, OLED displays, and LED panels due to their advantages of lightness, thinness, active light emission, fast response speed, wide viewing angle, rich colors, high brightness, low power consumption, and high and low temperature resistance. Therefore, the realization of large-size and high-resolution panels is the focus of current research and the development direction of future display technologies.

With the development of display technology, people have higher and higher requirements on the resolution and brightness of a display screen, but for a display panel with high resolution, as the requirement on the resolution is improved, the distance between light emitting areas of sub-pixels is smaller and smaller, for example, in the prior art submitted by the inventor, a flip chip space pixel arrangement structure is disclosed, red, green and blue sub-pixels are uniformly arranged at intervals to form a triangular mesh structure, and any adjacent three sub-pixels forming a triangle can form a white light pixel point. The structure provides higher pixel density, but the arrangement of the sub-pixels has an upper density limit due to the limitation of relevant factors such as the size of components and heat dissipation capacity. Therefore, new methods for improving display resolution are needed.

Disclosure of Invention

In order to achieve high resolution of a display screen, the application provides a flip chip spatial pixel arrangement structure, a pixel multiplexing method, a system, a device and a storage medium.

In a first aspect, the present application provides a pixel multiplexing method based on a flip chip spatial pixel arrangement structure, which adopts the following technical scheme:

a pixel multiplexing method based on a flip chip space pixel arrangement structure comprises the following steps:

dividing the LED display screen into a plurality of first pixel points and a second pixel set which are uniformly arrayed according to the equal spacing of rows and columns to form a light emitting tube array; the light emitting tube array is provided with a plurality of white light point groups, and each white light point group comprises three first-type white light points formed in each second pixel set, two first-type white light points formed between adjacent first pixel points and the second pixel sets, and two second-type white light points formed between adjacent second pixel sets;

sampling a single-frame original image with higher resolution into seven basic images with lower resolution based on a pixel acquisition algorithm, wherein pixels of each basic image are mapped with the same white light point of each group of white light point groups one by one;

formulating a display order of the basic images based on a judgment strategy, wherein the single-frame original images correspond to three display orders, and each display order corresponds to one or more basic images;

and sequentially displaying each low-resolution image within the duration of a single frame based on the display sequence to complete the sub-pixel recombination of the space pixel arrangement structure of the flip chip.

By adopting the technical scheme, the first-class white light spots are formed by the second pixel set or are generated by matching the first pixel point and the second pixel set, so that the light emission of the first-class white light spots cannot be influenced when other second pixel sets emit light. The second-class white light spot is a white light spot formed by matching sub-pixel points in two adjacent second pixel sets, and the corresponding sub-pixel points of the two second pixel sets are in an idle state in the display time sequence, or the interference sub-pixel points, namely the shared sub-pixel points, are modulated, so that the second-class white light spot can be simultaneously lightened when the adjacent first-class white light spots are lightened, and the utilization rate of the white light spot is improved.

Through a pixel acquisition algorithm, an original image with higher resolution is decomposed into seven basic patterns with lower resolution, and after the seven basic patterns with lower resolution are combined, an image with higher resolution can be formed. In order to improve the display efficiency, the pixels of the seven split basic images corresponding to the original image are different and respectively correspond to different white light points of the white light point group. Specifically, after each basic image is translated properly, most of the pixel points can be overlapped with the pixel points of other basic images. The first type white light points and the second type white light points may be lit up in different display orders, such as in a first display order, two non-adjacent first type white light points are lit up simultaneously for displaying two basic patterns. The seven images are displayed by the white light point group in three display orders. Since the refresh frequency of the base image is high, the human eye generates afterimage when receiving the base image, and thus the three display time-series patterns are overlapped, thereby generating the effect of high resolution by the high refresh rate.

Optionally, the determining policy includes:

judging whether the color difference between a first pixel point and an adjacent second pixel point in the basic image is larger than a preset threshold value, if so, modulating the brightness of three sub-pixels forming a second-order first-type white light spot and the brightness of two adjacent first pixel points so as to enable the color of a second-type white light spot formed by the five sub-pixel points to correspond to the basic image; and if not, canceling the display of the second type white light point in the second sequence to the second pixel point, and brightening the display brightness of the first type white light point corresponding to the similar pixel point, wherein the first pixel point and the second pixel point are respectively the pixel point of the first type white light point in the first sequence and the pixel point corresponding to the second type white light point in the white light point group corresponding to the same frame of original image, and the similar pixel point is the first pixel point.

By adopting the above technical solution, since the pixels are driven by the driver, the pixels are usually chips for controlling the scan driving circuit. To reduce cost, reduce heat generation and increase pixel density, this scheme combines multiple single-color sub-pixels into a pixel set, with a single driver for driving a single pixel set. That is, as long as the pixel points of the seven basic patterns sequentially correspond to the respective white light points of the white light point group, the single driver can sequentially drive without separately driving. The driver is corresponding to a buffer, and can store the seven-frame basic pattern split from each frame of original pattern. Because the second-class white light points have mutual interference of pixel points when in use, the controller reads two interfered basic images corresponding to the first sequence and the second sequence from the buffer before display to compare, judges whether the color difference between the first pixel point and the second pixel point at the interference position is larger than a preset threshold value, if so, determines that the first-class white light points of the second sequence and the second-class white light points of the second sequence share the sub-pixels, and modulates the luminous intensity of the sub-pixels to reduce color cast. The principle is based on the illusion that human eyes have limited resolution and can mix colors of adjacent pixel points, so that high color gradation is generated. Similarly, if the difference is small, the display brightness of the original first pixel point is improved, similar to the principle of PWM, two adjacent frames use one time of brightness respectively, and the two adjacent frames use two times of brightness at intervals, which are actually very close to each other in visual effect. Through the reality of merging similar pixel points, the calculation of the controller can be reduced, and the charging and discharging times of the circuit are reduced, so that the effect of saving power is achieved.

Optionally, the determining policy includes:

judging whether the color difference between a third pixel point and an adjacent second pixel point in the basic image is larger than a preset threshold value, if so, modulating the brightness of three sub-pixels forming a first white light spot of a second sequence and the brightness of two adjacent third pixel points so as to enable the color of a second white light spot formed by the five sub-pixel points to correspond to the basic image; and if not, canceling the display of the second type white light point in the second sequence to the second pixel point, and brightening the display brightness of the first type white light point corresponding to the similar pixel point, wherein the third pixel point and the second pixel point are respectively the pixel point of the third sequence first type white light point in the white light point group corresponding to the same frame of original image and the pixel point corresponding to the second sequence second type white light point, and the similar pixel point is the third pixel point.

By adopting the above technical solution, since the pixels are driven by the driver, the pixels are usually chips for controlling the scan driving circuit. To reduce cost, reduce heat generation and increase pixel density, this scheme combines multiple single-color sub-pixels into a pixel set, with a single driver for driving a single pixel set. That is, as long as the pixel points of the seven basic patterns sequentially correspond to the respective white light points of the white light point group, the single driver can sequentially drive without separately driving. The driver is corresponding to a buffer, and can store the seven-frame basic pattern split from each frame of original pattern. Because the second-class white light points are interfered with each other when in use, the controller reads two interfered basic images corresponding to the third sequence and the second sequence from the buffer before display to compare, judges whether the color difference between the third pixel point and the second pixel point at the interference position is larger than a preset threshold value, if so, determines that the first-class white light points of the second sequence and the second-class white light points of the second sequence share the interfered sub-pixels, and modulates the luminous intensity of the sub-pixels to reduce the color cast. The principle is based on the illusion that human eyes have limited resolution and can mix colors of adjacent pixel points, so that high color gradation is generated. Similarly, if the difference is small, the display brightness of the original third pixel point is improved, similar to the principle of PWM, two adjacent frames use one time of brightness respectively, and the two adjacent frames use two times of brightness at intervals, which are actually very close to each other in visual effect. Through the display of combining similar pixel points, the calculation of the controller can be reduced, and the charging and discharging times of the circuit can be reduced, so that the effect of saving power is achieved.

Optionally, the determining policy includes:

judging whether the color difference of the basic image corresponding to the third pixel point and the adjacent second pixel point is larger than a preset threshold value or not, judging whether the color difference of the basic image corresponding to the third pixel point and the adjacent second pixel point is larger than the preset threshold value or not, and if so, modulating the brightness of three sub-pixels forming the first white light spot of the second sequence and the brightness of two adjacent third pixel points so as to enable the color of the second white light spot formed by the five sub-pixel points to correspond to the basic image; and if not, canceling the display of the second type white light point in the second sequence to the second pixel point, and adjusting the display brightness of the first type white light point corresponding to the similar pixel point, wherein the first pixel point, the second pixel point and the third pixel point are respectively the pixel point of the first type white light point in the first sequence, the pixel point of the second type white light point in the second sequence and the pixel point of the first type white light point in the third sequence in the white light point group corresponding to the same frame of original image, and the similar pixel point is the pixel point of the first sequence or the third sequence, the color difference between the similar pixel point and the second pixel point is less than or equal to a preset threshold value.

By adopting the technical scheme, the two judgment strategies are integrated, and the interference pixel points generated by the corresponding basic images of the first light-emitting sequence, the second light-emitting sequence and the third light-emitting sequence are judged at the same time so as to merge the display of similar pixel points as much as possible, reduce the calculation of the controller, reduce the charging and discharging times of the circuit and achieve the effect of saving electricity.

Optionally, the step of modulating the brightness of three sub-pixels forming the second sequential white light spot and the brightness of two adjacent third pixel points to make the color of the second white light spot formed by the five sub-pixel points correspond to the color of the basic image includes:

acquiring the mapping relation between the three primary colors of the second pixel point and the similar pixel point and the three primary color sub-pixels of the corresponding white light point;

obtaining primary color development data of the three primary color sub-pixels of each white light point in the second sequence corresponding to the basic image, and adding and dividing the primary color development data corresponding to the common sub-pixels of each white light point by 2 to obtain the primary color development data of the common sub-pixels in the second sequence;

and transmitting the adjusted sub-pixel point display data and the unadjusted sub-pixel real point data of each white spot in the second sequence to the display screen based on the scanning driving circuit to control the corresponding white spot to emit light.

By adopting the technical scheme, four independent sub-pixels and a sub-pixel (namely the interference sub-pixel) shared by the first white light point and the second white light point exist in the two interfered white light points, the primary color development data of the two white light points corresponding to the two basic images are obtained, and the shared sub-pixel is displayed as the average value of the development data of the two basic images. In practical use, the color information received by the eyes is the average value of light emitted within a period of time, so that the method can improve the pixel density and the color expression accuracy.

In a second aspect, the present application provides a flip chip spatial pixel arrangement structure, which adopts the following technical scheme:

a flip-chip spatial pixel arrangement structure suitable for the pixel multiplexing method comprises a plurality of first pixel sets and a plurality of second pixel sets, the first pixel set comprises a plurality of first pixel points which are arranged in series, the first pixel points are A pixels, the second pixel set comprises a central sub-pixel and a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel which take the central sub-pixel as the center of a circle and are sequentially distributed on a semicircular arc, the central sub-pixel, the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel are respectively a first pixel, a second pixel, a third pixel, a second pixel and a third pixel, the A pixel, the B pixel and the C pixel are respectively one of a red sub-pixel, a green sub-pixel and a blue sub-pixel, three independent white light spots are formed in each second pixel set, the independent white light spot is formed by matching a central sub-pixel with any adjacent pixel on the corresponding semicircular arc; the second pixel set is located between the adjacent first pixel sets, the first sub-pixel and the second sub-pixel, the third sub-pixel and the fourth sub-pixel are respectively used as a recombination pair, the pixel arrangement structure is provided with a recombination position on one side of the recombination pair, which is far away from the central sub-pixel, an A pixel in the first pixel set is arranged on the recombination position and is matched with the adjacent recombination pair to form a first recombination white light spot, and the first pixel set and the second pixel set are independently electrically controlled to control the on-off sequence and the on-off frequency of the independent white light spot and the first recombination white light spot.

By adopting the technical scheme, the single second pixel set consists of five sub-pixels, three independent white light emitting points are formed in the single second pixel set, each white light emitting point is surrounded by one pixel A, one pixel B and one pixel C, namely, three groups of RGB form three white light emitting points, and the white light emitting points are generated without the cooperation of the first pixel set, so the white light emitting points are called independent light emitting points. Meanwhile, each recombination pair can be matched with pixels on the adjacent first pixel set to form a first recombination white light spot, namely, a sub-pixel point is additionally added, at least one white light spot is obtained, and compared with the second related technology, the second related technology is beneficial to improving the pixel density and simultaneously reduces the power consumption of the whole panel.

The second pixel set is located between the adjacent first pixel points, so that the arrangement rule of the first pixel points, the second pixel set and the first pixel points is presented in the transverse direction, the white light spots are continuously and uniformly arranged in the transverse direction, and the distance between the adjacent white light spots and the distance between the sub-pixels are in the same order of magnitude or even the same, so that the granular sensation of the pixels is remarkably reduced, and the requirements of electronic equipment and a high-definition image signal source on high resolution and high brightness of a display screen can be better met.

In addition, the sub-pixels of the same type are staggered and not arranged on the same straight line, so that color mixing of pixels in the unit panel size is facilitated, the expressive force of curves and oblique lines is improved, and the color cross phenomenon among the pixels is reduced while the pixel density is improved.

In the related art, the on-off of each pixel needs to be controlled by a driver, the on-off of the white spot is controlled by the on-off of the sub-pixel, and the sub-pixel is Pulse-width modulated (PWM) to control the brightness of the white spot. That is, in the related art, three sub-pixels or four sub-pixels are driven by one driver. In the scheme, five independent light-emitting points in the second pixel set are driven by a set of drivers, so that the second pixel set can continuously emit white light for multiple times, and the light-emitting period is prolonged. The first pixel in the first pixel set is also controlled by driving to control the on and off of the recombined white light spot and the luminous intensity in coordination with the driving of the second pixel.

For Liquid Crystal Display (LCD) or Oxide Light Emitting Diode (OLED), the pixel points can be controlled by Thin Film Transistors (TFTs), which are usually made of metal oxide and used for controlling the liquid crystal or light emitting oxide, are in a Thin Film structure and usually located on the light path, have a certain light transmittance and are provided with light passing ports, that is, when the pixels are more dense, the light passing ports are smaller if the driving volume is unchanged. The number of drives imposes a restriction on display quality. In the scheme, the back of the pixel can be set in the driving mode, so that the driving quantity does not influence the light transmission quantity, more drivers can be used under the condition of high pixel density, and various display indexes are improved.

In addition, in the Oxide Light Emitting Diode (OLED) technology, the diamond arrangement and the delta arrangement of the RGB sub-pixels of the related art are similar to those of the present solution, but in fact, there is a substantial difference. The diamond arrangement and the delta arrangement in the east of Beijing aim at solving the problem that the service lives of RGB three-color sub-pixels of the OLED are greatly different, namely the commonly known screen burning problem. Therefore, the delta arrangement in the east of kyoto enables the areas of the blue and red sub-pixels having lower lifetimes to be set larger to compensate for the chromatic aberration. Furthermore, after the diamond arrangement or delta arrangement in the east of Beijing will result in a decrease in pixel density. In the scheme, the arrangement mode is adopted to solve the problem of low pixel density, and because the service lives of the red sub-pixel, the green sub-pixel and the blue sub-pixel are close to each other, the corresponding relations between the pixels A, B and C and the red sub-pixel, the green sub-pixel and the blue sub-pixel are not limited, and only one-to-one correspondence is needed, namely six corresponding relations can be provided, which cannot be realized in diamond arrangement and delta arrangement in Jing east. Similarly, the setting areas of the pixels A, B and C are also close, so that the dense arrangement can be realized, which cannot be realized by diamond arrangement and delta arrangement in the east of Beijing.

Optionally, the central sub-pixel and any pair of adjacent sub-pixels on the corresponding semicircular arc form a central angle of 60 degrees, and the recombination position and the A pixel on the corresponding recombination position are arranged in an equilateral triangle.

By adopting the technical scheme, the first sub-pixel, the second sub-pixel and the central sub-pixel define an equilateral triangle, the second sub-pixel, the third sub-pixel and the central sub-pixel define an equilateral triangle, the third sub-pixel, the fourth sub-pixel and the central sub-pixel define an equilateral triangle, in other words, if the first sub-pixel, the second sub-pixel, the third sub-pixel, the fourth sub-pixel, the central sub-pixel and the first sub-pixel are sequentially connected to define an isosceles trapezoid, two end points at the bottom side of the isosceles trapezoid define the first sub-pixel and the fourth sub-pixel, and two end points at the top side define the second sub-pixel and the third sub-pixel. The reset group is arranged in an equilateral triangle with the A pixel on the corresponding reset position, so that the independent white light spots and the first reset white light spots are uniformly arranged, and compared with the arrangement modes at other angles, the spatial pixels can not be distorted, or the hue position does not need to be adjusted for correcting distortion, and the spatial pixel displacement does not need to be carried out by a control system.

Optionally, the second pixel sets are longitudinally arranged in a single row between adjacent first pixel sets, in any two adjacent upper and lower second pixel sets, a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel of the upper second pixel set and a second sub-pixel and a third sub-pixel of the lower second pixel set form a regular hexagon structure, four sub-pixels at the lower part of the regular hexagon structure cooperate with an a pixel at the center of the regular hexagon structure to form three second recombination white light spots, and two adjacent second pixel sets respectively control the on and off of pixels inside the second pixel sets to control the on and off sequence and the on and off frequency of the second recombination white light spots; four sub-pixels of regular hexagon structure lower part divide into two cooperation pairs according to controlling, the cooperation forms the white light spot of third reorganization with the first pixel cooperation on the adjacent reorganization position, adjacent two the second pixel set controls the bright and dark of the inside pixel of self respectively just first pixel set controls the bright and dark of the inside first pixel of self in order to control the bright and dark of the white light spot of third reorganization.

By adopting the technical scheme, the second pixel sets adjacent to each other can be recombined in space to emit white light for three times, the pixel set of each second recombined white light point is 1R1G1B, the ratio of the sub-pixels is 1:1:1, and the white light mixing ratio is 3:6: 1. The distances between the white light-emitting points in the transverse direction and the longitudinal direction are uniform, the pixel arrangement is more uniform, and the visual pixel granular feeling is avoided. In addition, the second pixel set can emit three times of white light, and the adjacent second pixel set can also emit multiple times of white light, so that higher pixel density is obtained, the resolution of the panel is further improved, and the modulation capability of driving the light emission of the single pixel set can also be improved.

The embodiment of the application discloses a flip chip spatial pixel arrangement structure, which is used in the field of micro-LED or mini-LED self-luminous display. Referring to fig. 1, the pixel arrangement structure is divided according to a driving relationship, and includes a plurality of first pixel sets 1 and a plurality of second pixel sets 2, where the first pixel sets 1 include a plurality of first pixel points that are continuously arranged, and the first pixel points are first pixels, and due to the difference between the substrate and the product type, in some embodiments, the first pixel sets 1 may be arranged in a single-row curved line, in other embodiments, the first pixel sets 1 may be arranged in a single-row straight line, and only two adjacent sets of the first pixel sets 1 need to be parallel to each other or overlapped in a translation manner.

Referring to fig. 1 and 2, the plurality of second pixel sets 2 are disposed between two adjacent first pixel sets 1, and specifically, each second pixel set 2 is arranged in an extending direction of the first pixel set 1.

The areas of the red, blue and green sub-pixels are the same compared to the OLED without a need for a compensatory increase in the light emitting areas of the blue and red sub-pixels, and therefore the correspondence of the a, b and c pixels to the green, blue and red sub-pixels may be chosen differently in different embodiments. Specifically, in some embodiments, the a pixel is a red sub-pixel, the b pixel is a blue sub-pixel, and the c pixel is a green sub-pixel; in other embodiments, the first pixel is a red sub-pixel, the second pixel is a green sub-pixel, and the third pixel is a blue sub-pixel; in other embodiments, the first pixel is a blue sub-pixel, the second pixel is a red sub-pixel, and the third pixel is a green sub-pixel; in other embodiments, the first pixel is a blue sub-pixel, the second pixel is a green sub-pixel, and the third pixel is a red sub-pixel; in other embodiments, the first pixel is a green sub-pixel, the second pixel is a red sub-pixel, and the third pixel is a blue sub-pixel; in other embodiments, the A pixel is a green sub-pixel, the B pixel is a blue sub-pixel, and the C pixel is a red sub-pixel. In this embodiment, the first pixel is a red sub-pixel, the second pixel is a blue sub-pixel, and the third pixel is a green sub-pixel.

The central angle of the central sub-pixel 201 with any pair of adjacent sub-pixels on the corresponding half-circle arc may be different, and in some embodiments, may form a central angle of 65 °, or a central angle of 55 °, or other central angle other than 60 °. Since the triangle formed by the central sub-pixel 201 and the adjacent sub-pixels on the corresponding half-arc is not an equilateral triangle, the distortion of the spatial pixel will occur, and the color phase position needs to be adjusted to correct the distortion, so that the spatial pixel shift can be performed by the control system. To reduce the amount of computation by the control system, in some embodiments, the central sub-pixel 201 forms a 60 ° central angle with any pair of adjacent sub-pixels on the corresponding semi-circular arc. That is, the first sub-pixel 202, the second sub-pixel 203 and the center sub-pixel 201 form an equilateral triangle, the second sub-pixel 203, the third sub-pixel 204 and the center sub-pixel 201 form an equilateral triangle, and the third sub-pixel 204, the fourth sub-pixel 205 and the center sub-pixel 201 form an equilateral triangle. In other words, if the first subpixel 202, the second subpixel 203, the third subpixel 204, the fourth subpixel 205, the center subpixel 201, and the first subpixel 202 are sequentially connected to form an isosceles trapezoid, two end points of the bottom side of the isosceles trapezoid are the first subpixel 202 and the fourth subpixel 205, and two end points of the top side are the second subpixel 203 and the third subpixel 204.

Thus, three independent white light spots 301 are formed in the second pixel set 2, and each independent white light spot 301 is formed by matching the central sub-pixel 201 with any adjacent pixel on the corresponding semicircular arc. Each white light emitting point is surrounded by an a pixel, a b pixel and a c pixel, that is, three groups of RGB form three white light emitting points, which are generated without cooperation of the first pixel set 1, and thus are called independent light emitting points.

Referring to fig. 1 and 3, the first subpixel 202 and the second subpixel 203, and the third subpixel 204 and the fourth subpixel 205 form a recombination pair, the pixel arrangement structure forms a recombination site on a side of the recombination pair away from the central subpixel 201, and the a pixel in the first pixel set 1 is disposed on the recombination site and cooperates with the adjacent recombination pair to form a first recombination white spot 302. Furthermore, the recombination group and the A pixel on the corresponding recombination position are arranged in an equilateral triangle. The arrangement rule of the first pixel set 1, the second pixel set 2 and the first pixel set 1 is presented in the transverse direction, the white light spots are continuously and uniformly arranged in the transverse direction, and the distance between the adjacent white light spots is the same as that between the sub-pixels, so that the graininess of the pixels is obviously reduced, and the requirements of electronic equipment and a high-definition image signal source on high resolution and high brightness of a display screen can be better met.

In addition, each group of the recombination pairs can cooperate with the pixels on the adjacent first pixel set 1 to form a first recombined white light spot 302, that is, an additional sub-pixel point is added, at least one white light spot is obtained, which is beneficial to improving the pixel density and simultaneously reduces the power consumption of the whole panel.

Referring to fig. 4, for any two second pixel sets 2 adjacent up and down, the relative distance may be different in different embodiments, in order to avoid distortion of spatial pixels, in some embodiments, the first sub-pixel 202, the second sub-pixel 203, the third sub-pixel 204, and the fourth sub-pixel 205 of the upper second pixel set 2 and the second sub-pixel 203 and the third sub-pixel 204 of the lower second pixel set 2 form a regular hexagon structure, and the four sub-pixels at the lower part of the regular hexagon structure cooperate with the a pixel at the center of the regular hexagon structure to form three second recombination white spots 303. Therefore, all the sub-pixels of the first pixel set 1 and the second pixel set 2 are uniformly arranged in a net shape.

The first pixel set 1 and the second pixel set 2 are independently electrically controlled to control the on-off sequence and the on-off frequency of the independent white light spot 301 and the first recombined white light spot 302, and two adjacent second pixel sets 2 respectively control the on-off of the pixels in the second pixel set to control the on-off sequence and the on-off frequency of the second recombined white light spot 303. Specifically, the on-off of each pixel needs to be controlled by a driver, the on-off of the white spot is controlled by the on-off of the sub-pixel, and Pulse-width modulation (PWM) is performed on the sub-pixel to control the brightness of the white spot. The scheme drives five independent light-emitting points in the second pixel set 2 through a set of drivers, so that the second pixel set 2 can continuously emit white light for multiple times, and the light-emitting period is prolonged. The first pixel in the first pixel set 1 is also controlled by driving to control the on/off and the luminous intensity of the recombined white light spot in cooperation with the driving of the second pixel.

Referring to fig. 4, adjacent sub-pixels of two adjacent second pixel sets 2 also enclose an RGB area to form a white light spot, specifically, the four sub-pixels at the lower part of the regular hexagonal structure are divided into two matching pairs at left and right, that is, a first sub-pixel 202 of the upper second pixel set 2 and a second sub-pixel 203 of the lower second pixel set 2 form a matching pair, and a fourth sub-pixel 205 of the upper second pixel set 2 and a second sub-pixel 203 of the lower third sub-pixel 204 set form a matching pair. The matching pair is matched with the A pixel on the adjacent recombination position to form a third recombination white light spot 304, the adjacent two second pixel sets 2 respectively control the on-off of the pixel inside the second pixel sets, and the first pixel set 1 is matched to control the on-off of the A pixel inside the second pixel sets, so that the on-off of the third recombination white light spot 304 is controlled.

Specifically, in order to make full use of the flip chip spatial pixel arrangement structure, the application also discloses a pixel multiplexing method based on the flip chip spatial pixel arrangement structure, which is used for controlling the light emission of the sub-pixel points on the LED display screen so as to control the white light spot to emit light as much as possible within the display frequency as less as possible without interference. Referring to FIG. 5, it includes at least four steps S1-S4.

S1, dividing an LED display screen into a plurality of first pixel points and a second pixel set 2 which are uniformly arrayed according to line and column equal intervals to form a light emitting tube array; the light emitting tube array is formed with a plurality of white light point groups, each white light point group includes three first-type white light points 4 formed inside each second pixel set 2, two first-type white light points 4 formed between the adjacent first pixel points and the second pixel sets 2, and two second-type white light points 5 formed between the adjacent two second pixel sets 2.

Referring to fig. 6, based on the foregoing embodiment of the flip chip spatial pixel arrangement structure, five first-type white light spots 4 are a first white light spot 41, a second white light spot 42, a third white light spot 43, a fourth white light spot 44, and a fifth white light spot 45 from left to right, two second-type white light spots 5 are a sixth white light spot 51 and a seventh white light spot 52 from left to right, in fact, the second white light spot 42, the third white light spot 43, and the fourth white light spot 44 are independent white light spots 301, the first white light spot 41 and the fifth white light spot 45 are first recombined white light spots 302, and the sixth white light spot 51 and the seventh white light spot 52 are third recombined white light spots 304. That is, the first white light point 41 and the fourth, fifth, and seventh white light points 52 do not have a common subpixel, the second white light point 42 and the fifth and seventh white light points 52 do not have a common subpixel, the third white light point 43 and the other six white light points all have a common subpixel, the fourth white light point 44 and the first and sixth white light points 51 do not have a common subpixel, and the fifth white light point 45 and the first, second, and sixth white light points 51 do not have a common subpixel. In addition, two white light point groups adjacent to each other on the left and right share a first pixel point, that is, a white light point number five 45 of the white light point group on the left and a white light point number one 41 of the white light point group on the right share a sub-pixel.

And S2, sampling a single-frame original image with higher resolution into seven basic images with lower resolution based on a pixel acquisition algorithm, wherein pixels of each basic image are mapped with the same white light point of each group of white light point groups one by one.

Through a pixel acquisition algorithm, an original image with higher resolution is decomposed into seven basic patterns with lower resolution, and after the seven basic patterns with lower resolution are combined, an image with higher resolution can be formed. In order to improve the display efficiency, the pixels of the seven split basic images corresponding to the original image are different and respectively correspond to different white light points of the white light point group. Specifically, after each basic image is translated properly, most of the pixel points can be overlapped with the pixel points of other basic images. For example, referring to fig. 7, the original image 7-a with higher resolution can be split into basic images 7-b, 7-c, 7-d, 7-e, 7-f, 7-g, 7-h with lower resolution, and the pixel points of each basic image correspond to the white light points at the same position of each white light point group, so that it can also be seen that the white light points in each image of fig. 7 are uniformly distributed as a whole. It should be noted that fig. 7 is only used to illustrate a method for splitting an original image with a higher resolution into 7 lower resolution images in an embodiment, and a specific form of the splitting is not specifically limited, for example, the pixels depicted in fig. 7 are not uniform and are completely split, in practice, a single pixel of the original image may be repeatedly split into multiple basic images, and only the brightness of the repeated pixels needs to be reduced so that the brightness of the overlapped pixels after the basic images are overlapped corresponds to the brightness of the original image. It is of course also possible to discard a part of the pixels of the original image during the sampling process, instead of displaying them on the base image.

And S3, formulating display sequences of the basic images based on the judgment strategy, wherein the single-frame original images correspond to three display sequences, and each display sequence corresponds to one or more basic images.

The first type of white light spots 4 and the second type of white light spots 5 may be lit up in different display orders, such as in the first display order, two non-adjacent first type of white light spots 4 are lit up simultaneously for displaying two basic patterns. The seven images are displayed by the white light point group in three display orders. For example, based on the above-described embodiment of the flip-chip spatial pixel arrangement, the white light dots displayed in the first order 61 are the white light dot No. two 42 and the white light dot No. five 45, the white light dots displayed in the second order 62 are the white light dot No. three 43, the white light dot No. six 51 and the white light dot No. seven 52, and the white light dots displayed in the third order 63 are the white light dot No. one 41 and the white light dot No. four 44. The partial images corresponding to the white light point number six 51 and the white light point number seven 52 in the second order 62 are finely adjusted based on the determination policy, so that the partial images are merged and displayed in the first order 61 or the third order 63.

Specifically, in some embodiments, the determining the policy includes:

judging whether the color difference between the first pixel point and the adjacent second pixel point in the basic image is larger than a preset threshold value, if so, modulating the brightness of three sub-pixels of the first-type white light point 4 forming the second sequence 62 and the brightness of the adjacent two first pixel points, so that the color of the second-type white light point 5 formed by the five sub-pixel points corresponds to the basic image; if not, the display of the second type white light point 5 in the second sequence 62 on the second pixel point is cancelled, and the display brightness of the first type white light point 4 corresponding to the similar pixel point is adjusted to be bright, wherein the first pixel point and the second pixel point are respectively the pixel point of the first type white light point 4 in the first sequence 61 and the pixel point of the second type white light point 5 corresponding to the second sequence 62 in the white light point group corresponding to the same frame of original image, and the similar pixel point is the first pixel point.

Since the pixels are driven by the driver, they are usually chips for controlling the scan driving circuit. To reduce cost, reduce heat generation and increase pixel density, this scheme combines multiple single-color sub-pixels into a pixel set, with a single driver for driving a single pixel set. That is, as long as the pixel points of the seven basic patterns sequentially correspond to the respective white light points of the white light point group, the single driver can sequentially drive without separately driving. The driver is corresponding to a buffer, and can store the seven-frame basic pattern split from each frame of original pattern. Because the second-type white light point 5 has mutual interference of pixel points when in use, the controller reads two interfered basic images corresponding to the first sequence 61 and the second sequence 62 from the buffer before display and compares the two interfered basic images, judges whether the color difference between the first pixel point and the second pixel point at the interference position is larger than a preset threshold value, if so, determines that the first-type white light point 4 of the second sequence 62 and the second-type white light point 5 of the second sequence 62 share a sub-pixel, and modulates the luminous intensity of the sub-pixel to reduce color cast. The principle is based on the illusion that human eyes have limited resolution and can mix colors of adjacent pixel points, so that high color gradation is generated. Similarly, if the difference is small, the display brightness of the original first pixel point is improved, similar to the principle of PWM, two adjacent frames use one time of brightness respectively, and the two adjacent frames use two times of brightness at intervals, which are actually very close to each other in visual effect. Through the reality of merging similar pixel points, the calculation of the controller can be reduced, and the charging and discharging times of the circuit are reduced, so that the effect of saving power is achieved.

For example, when the light emitting intensity of the blue sub-pixel corresponding to the basic image pixel corresponding to the second white light point 42 is 100 units, the light emitting intensity of the blue sub-pixel corresponding to the basic image pixel corresponding to the sixth white light point 51 is 101 units, and the preset threshold is 10 units, it is determined that the color difference between the first pixel point and the adjacent second pixel point in the basic image is smaller than the preset threshold, and during displaying, the display of the frame original object corresponding to the sixth white light point 51 in the second order 62 is cancelled, and the light emitting intensity of the second white light point 42 in the first order 61 is adjusted to 200 units. For another example, when the light emitting intensity of the blue sub-pixel corresponding to the basic image pixel corresponding to the white light point No. two 42 is 100 units, the light emitting intensity of the blue sub-pixel corresponding to the basic image pixel corresponding to the white light point No. six 51 is 120 units, and the preset threshold is 10 units, it is determined that the color difference between the first pixel point and the adjacent second pixel point in the basic image is greater than the preset threshold, so that in the second sequence 62, during displaying, the display of the frame original object corresponding to the white light point No. six 51 in the second sequence 62 is continued, but the light emitting intensity of the blue sub-pixel shared by the white light point No. three 43 and the white light point No. six 51 is adjusted.

In other embodiments, determining the policy includes:

judging whether the color difference between the third pixel point and the adjacent second pixel point in the basic image is larger than a preset threshold value, if so, modulating the brightness of three sub-pixels of the first type white light point 4 forming the second sequence 62 and the brightness of the adjacent two third pixel points, so that the color of the second type white light point 5 formed by the five sub-pixel points corresponds to the basic image; if not, the display of the second type white light point 5 in the second sequence 62 on the second pixel point is canceled, and the display brightness of the first type white light point 4 corresponding to the similar pixel point is adjusted to be bright, wherein the third pixel point and the second pixel point are respectively the pixel point of the third sequence 63 first type white light point 4 in the white light point group corresponding to the same frame of original image and the pixel point corresponding to the second type white light point 5 in the second sequence 62, and the similar pixel point is the third pixel point.

In other embodiments, determining the policy includes:

judging whether the color difference corresponding to a third pixel point and an adjacent second pixel point in the basic image is larger than a preset threshold value or not, judging whether the color difference corresponding to the third pixel point and the adjacent second pixel point in the basic image is larger than the preset threshold value or not, and if so, modulating the brightness of three sub-pixels of a first type white light point 4 forming a second sequence 62 and the brightness of two adjacent third pixel points so as to enable the color of a second type white light point 5 formed by the five sub-pixel points to correspond to the basic image; and if not, canceling the display of the second type white light point 5 in the second sequence 62 on the second pixel point, and brightening the display brightness of the first type white light point 4 corresponding to the similar pixel point, wherein the first pixel point, the second pixel point and the third pixel point are respectively a pixel point of the first type white light point 4 in the first sequence 61, a pixel point of the second type white light point 5 corresponding to the second sequence 62 and a pixel point of the first type white light point 4 corresponding to the third sequence 63 in the white light point group corresponding to the same frame of original image, and the similar pixel point is a pixel point of the first sequence 61 or the third sequence 63, the color difference between the similar pixel point and the second pixel point is less than or equal to a preset threshold value.

The two judgment strategies are integrated, and the interference pixel points generated by the corresponding basic images of the first light-emitting sequence, the second light-emitting sequence and the third light-emitting sequence are judged at the same time, so that the display of similar pixel points is combined as much as possible, the calculation of a controller can be reduced, the charging and discharging times of a circuit are reduced, and the effect of saving electricity is achieved.

Although in different embodiments, the representation of the determination strategy may be different, in these determination steps, the step of modulating the luminances of three sub-pixels of the first type white light spot 4 and the luminances of two adjacent third pixel points that constitute the second order 62, so that the color of the second type white light spot 5 formed by these five sub-pixel points corresponds to the basic image, includes:

acquiring primary color rendering data of the three primary color sub-pixels of each white light point of the second order 62 corresponding to the basic image, and adding and dividing the primary color rendering data corresponding to the common sub-pixels of each white light point by 2 to obtain the primary color rendering data of the common sub-pixels in the second order 62;

the adjusted sub-pixel point display data and the unadjusted sub-pixel real point data of each white spot in the second order 62 are transmitted to the display screen based on the scanning driving circuit to control the corresponding white spot to emit light.

In the two interfered white light points, four independent sub-pixels exist, and one sub-pixel (namely, an interference sub-pixel) shared by the first type white light point 4 and the second type white light point 5 is obtained, the two white light points correspond to the primary color development data of the two basic images, and the shared sub-pixel is displayed as the average value of the development data of the two basic images. In practical use, the color information received by the eyes is the average value of light emitted within a period of time, so that the method can improve the pixel density and the color expression accuracy.

Taking the above example, if the light-emitting intensity of the blue sub-pixel corresponding to the basic image pixel corresponding to the white light point No. two 42 is 100 units, the light-emitting intensity of the blue sub-pixel corresponding to the basic image pixel corresponding to the white light point No. six 51 is 120 units, and the preset threshold is 10 units, it is determined that the color difference between the first pixel point and the adjacent second pixel point in the basic image is greater than the preset threshold, so in the second sequence 62, and further during displaying, the frame original object is displayed corresponding to the white light point No. six 51 in the second sequence 62, but the light-emitting intensity of the blue sub-pixel shared by the white light point No. three 43 and the white light point No. six 51 is adjusted, so that the light-emitting intensity of the blue sub-pixel is adjusted to (100 + 120)/2 =110 units.

And S4, sequentially displaying each low-resolution image within the duration of a single frame based on the display sequence to complete the sub-pixel recombination of the space pixel arrangement structure of the flip chip.

Since the refresh frequency of the base image is high, the human eye generates afterimage when receiving the base image, and thus the three display time-series patterns are overlapped, thereby generating the effect of high resolution by the high refresh rate. Specifically, the display duration of each low-resolution image may be different, for example, in some embodiments, the refresh frame rate of the original image is 60Hz, and the refresh frame rate of the basic images is 180Hz, that is, in the first order 61, the basic images corresponding to the white light point No. two 42 and the white light point No. five 45 are refreshed, in the second order 62, the basic images corresponding to the white light point No. three 43, the white light point No. six 51 and the white light point No. seven 52 are refreshed, and in the third order 63, the basic images corresponding to the white light point No. one 41 and the white light point No. four 44 are refreshed.
