[0031] Figure 1A high-resolution dynamic light-emitting display device based on virtual pixels according to the present application comprises:

[0032] The display unit 1 is arranged in a strip shape, and can be composed of a single display unit or a plurality of display units according to the size of the horizontal span of the display area to form an array capable of synchronously updating the displayed image in the display area, wherein each display unit is respectively arranged with a display array along the axial direction of its strip, and the display array has at least two display light output directions, and the output direction of the display light usually corresponds to the light outgoing angle interval corresponding to the circumference of the display unit, and the top of each of the display units 1 is also respectively provided with a plurality of electrode interfaces along the outer edge of its end face, and the display unit is also connected with a transmission structure, and is driven by the transmission structure to run along the driving track;

[0033] The driving track 2 is arranged in at least one layer along the display area, and is used to clamp and fix the top of each display unit 1, suspend the display unit in the display area and accommodate the movement of each display unit in the display area. During the movement, the inner wall of the driving track is also embedded with a plurality of electrode driving ports along the moving direction of the display unit, which are used to feed display driving signals to the electrode interfaces of the television units in different rotation states to trigger different light-emitting states of each pixel unit in the display array;

[0034] During the movement of the display unit 1 along the driving track 2, the display unit 1 is driven by the transmission mechanism to simultaneously realize rolling rotation in the clamping area of ​​the track 2 and move forward or backward accordingly along the arrangement direction of the driving track 2. The display light output directions of the display unit rotate alternately in turn to the visual reception area of ​​the viewer, and the display arrays and their afterimages in the display light output directions together constitute a display image in the visual reception area of ​​the viewer.

[0035] The imaging process can be referred to Figure 1 , the display unit rotates and moves along the track at the same time. For the human eye in a fixed position on one side of the track, the rotation of the display unit will rotate its display arrays in different outward directions to the visual area of ​​the human eye in sequence. Since the rotation frequency of the display unit is relatively fast, the display arrays in various directions will produce afterimages in the human eye. The afterimage and the light of the current display array of the display unit enter the human eye to form a pixel matrix distributed along the plane where the track is located, and the different color effects of each pixel in the pixel matrix can form a complete display image arranged along the track. Since the display unit body is only a long strip structure, it will not block the scene image on the back side of the track too much when radiating the display light of each array outward. Therefore, the display unit can display the corresponding pattern during operation and will not block the background on the back side of the track too much. Therefore, the display effect of the present application can achieve additional rendering effects on the background scene in a larger frame area.

[0036] Reference Figure 1 In order to improve the pixel display effect of the display unit and increase its color resolution, the present application preferably arranges the pixel units installed in the adjacent light output directions of the ligands of the display array in the display unit 1 in an interlaced manner, and arranges the colors corresponding to the first pixel units installed in the adjacent light output directions in a circular manner in the order of red, green, and blue, and arranges the colors corresponding to a column of pixel units installed in the same light output direction on the ligands in the display unit 1 in a circular manner in the order of red, green, and blue.

[0037] Since the pixel units of two adjacent columns in the display unit 1 are arranged in a staggered manner, Figure 1 Taking the left column as an example, after rotation, the adjacent column of pixel units is located exactly at the gap between the pixels in the leftmost residual image. Therefore, for the human eye, since the distance between the two columns of pixels is smaller than the angle of separation of the human eye, the four pixels in the two adjacent columns will be combined into one sub-pixel, for example Figure 1 The RB pixel at the top of the leftmost column and the GR pixel in the second column from the left are close to each other and will be recognized as a sub-pixel composed of three RGB colors by the human eye. Each sub-pixel module contains a first color light, a second color light and two third color lights among the three RGB colors. The two third color lights in the sub-pixel module are located in the upper left corner and the lower right corner of the tiny quadrilateral formed by the four pixels, and the first color light and the second color light are respectively located between the two third color lights of the quadrilateral of the sub-pixel module, and the first color light and the second color light are offset from each other in the row direction and the column direction.

[0038] by Figure 1 Taking the second group of sub-pixel modules in the third and fourth columns from the left as an example, the upper right corner of the second group of sub-pixel modules in the fourth column from the left is a green light-emitting unit marked with G, which corresponds to the first color light of the sub-pixel module, and is aligned with the third color light of the red light-emitting unit marked with R in the third column and the third row corresponding to the upper left corner of the sub-pixel module in the column direction, and the first color light is misaligned with the third color light in the lower right corner of the matrix in the row direction; correspondingly, the blue light-emitting unit marked with B corresponding to the fourth light-emitting potential in the third column in the sub-pixel module, the second color light is aligned with the third color light in the lower right corner of the sub-pixel module in the column direction, and the second color light is misaligned with the third color light in the upper left corner of the matrix in the row direction.

[0039] Since each sub-pixel module contains a first color pixel module, a second color pixel module and two third color pixel modules, they are arranged in sequence in the row direction and arranged alternately in the column direction. This arrangement can increase the number of pixels, thereby improving the resolution of the display screen and the fineness of the image. The three sub-pixel modules in each physical pixel unit can synthesize detailed and rich colors and grayscale levels, making the viewed image clearer and more realistic.

[0040] At the same time, due to the staggered arrangement of the color light pixel modules in the present application, in any two columns of residual images circled in the present application, the four adjacent light-emitting pixel units at any position all contain the three primary colors of red, green and blue, so they can all form a colored pixel point in the human eye. Therefore, when the display unit is running, the pixel points in the residual image produced in the human eye can be more dense: Figure 1 For example, in the first and second columns from the left, the first and second light-emitting elements pointing vertically downward can jointly constitute a virtual pixel composed of four RGBR light-emitting modules arranged clockwise, and the visual center displayed in the human eye is located at the center of the four RGBR light-emitting modules arranged clockwise. At the same time, in the first and second columns, the second and third light-emitting elements pointing vertically downward can jointly constitute a virtual pixel composed of four BRBG light-emitting modules arranged clockwise, and the visual center displayed in the human eye is located at the center of the four BRBG light-emitting modules arranged clockwise. The position difference between the above two virtual pixels actually corresponds to the installation space of only one light-emitting element. Similarly, in the second and third columns, the first and second light-emitting elements pointing vertically downward can jointly constitute a virtual pixel composed of four GBGR light-emitting modules arranged clockwise, and the visual center displayed in the human eye is located at the center of the four GBGR light-emitting modules arranged clockwise. In the second and third columns, the second and third light-emitting elements pointing vertically downward can together form a virtual pixel composed of four light-emitting modules RGRB arranged clockwise, and the visual center displayed in the human eye is located at the center of the four light-emitting modules RGRB arranged clockwise. Therefore, the present application can form a virtual pixel near each light-emitting element through the aforementioned special arrangement of light-emitting elements, thereby expanding the display pixels of the display device to be consistent with the number of rows and columns of its light-emitting elements by regulating the light and dark ratios of each color of light-emitting elements, without the need to combine at least three RGB light-emitting elements into an effective pixel that displays color as in the traditional way. Therefore, the present application can achieve a more delicate pixel display effect with a limited number of light-emitting elements, thereby improving the resolution of the display device and achieving a high-resolution dynamic display effect based on virtual pixels.

[0041] Two third color lights are placed in the upper left corner and the lower right corner of the matrix, and the first color light and the second color light are both between the two third color lights. This design arrangement can provide more accurate and balanced color reproduction capabilities. By arranging sub-pixels of different colors at different positions, color shift and color cross-interference can be eliminated, making the displayed color more accurate and consistent. In addition, since the positions of the light-emitting elements in the residual images of each column in the present application are staggered with each other, the first color light and the second color light in each sub-pixel module are arranged in a staggered manner in the row and column directions, and the first color light is aligned with the third color light in the upper left corner of the matrix in the column direction, and the second color light is aligned with the third color light in the lower right corner of the matrix in the column direction. Therefore, the driving circuit structure corresponding to each light-emitting element can simplify its arrangement by utilizing the gap position between adjacent columns, reduce the cross-interference of color signals and complex mapping relationships, thereby simplifying the design and production process of the display unit.

[0042] The specific arrangement structure provided in this embodiment effectively disperses the singleness of the vertically arranged pixel units through the staggered circular arrangement formed by the physical pixel units, unifies the distribution of the pixel points formed by the afterimage of the pixel units on the other side in the row direction, and makes them cooperate with each other to effectively eliminate the differences in pixel color distribution in each direction, and realizes a uniform circular layout of different types of pixel distribution in the row and column directions, which is not easy to form boundary differences between sub-pixel modules. At the same time, the staggered distribution of each light-emitting unit inside the sub-pixel module can also realize the mutual nesting of display effects in each distribution direction, thereby further improving the display effect of the visual unit, avoiding the sense of separation of the boundaries between sub-pixel modules, and further improving the visual effect of the overall display unit. In this application, the sub-pixel module can be realized by the LED sub-pixel arrangement structure, and can also be realized based on the arrangement and distribution of the OLED display unit. On the basis of following the original three primary colors (sub-pixel) unit, it can ensure that the number of each type of color unit of RGB (red, green and blue) in the figure is completely equal through the distribution of each primary color display unit, so that each primary color and the surrounding sub-pixel unit can achieve a uniform periodic distribution state through a circular arrangement. Each sub-pixel module presents a quadrilateral with non-equivalent distribution of base colors at its four corners, which can form a more uniform pixel staggered distribution form through the extension of the position. As a result, this arrangement allows the present application to use fewer color output units to present a display screen with higher resolution and smaller granularity. By placing two pixels of the same color in diagonal positions, the present application can also effectively reduce the discontinuity of color transitions, making the image transition smoother, and greatly weakening the granularity caused by the gaps between the sub-pixel modules. The second color light and the third color light are arranged in a staggered manner in the row and column directions, and this mutually staggered arrangement can also effectively reduce cross-contamination between colors. Between the lateral afterimages, the staggered arrangement of the light-emitting unit potentials of different sub-pixel modules in different directions can also reduce the mutual interference of color signals between adjacent pixels and improve the independence and color accuracy of each sub-pixel module.

[0043] This arrangement of sub-pixel modules composed of light-emitting elements can provide high-resolution and delicate image display in terms of visual characteristics, enhance color accuracy and balance, and make full use of the staggered gaps between the light-emitting units to simplify the layout design of the driving circuit, so that the overall display unit can present more realistic, clear and high-quality images.

[0044] Specifically Figure 2For example, in the present application, the display unit 1 can be set as a prism assembly including two layers of inner and outer cross-sections with a polygonal structure of constant width or a curved prism assembly with two layers of inner and outer cross-sections with a polygonal structure of constant width. Each side of the prism assembly or the curved prism assembly corresponds to a display light output direction, and since the side of the prism is relatively flat, it can avoid interference with the light path of the light-emitting unit in the array; at the same time, the polygonal cross-section with a constant width can ensure that each display unit can remain stuck in the track structure with a fixed width during rotation, maintain the electrical triggering state with the electrode structure in the track, and realize the feeding of the internal light-emitting element.

[0045] A pair of cathodes 102 and anodes 101 are embedded in the inner and outer two layers of prism assemblies or curved prism assemblies, and a light-emitting unit structure composed of an emission layer and a conductive layer is respectively arranged between each of the cathodes and anodes; the cathode 102, the emission layer 104, the conductive layer 103 and the anode 101 together constitute a light-emitting element, which realizes the corresponding light wavelength through different doping of the emission layer, and constitutes a pixel unit of the display array. Adjacent pixel units use their own luminous afterimages to form a sub-pixel module presented to the human eye, and the complete display image is formed by the interlaced superposition of each sub-pixel module. The height position of the pixel unit installed on the side of the prism assembly or curved prism assembly in the display unit 1 corresponds to the gap position between the pixel units installed on its adjacent side. Therefore, for a display unit, two adjacent pixel units on one of its light-emitting sides constitute the left two colors of a sub-pixel module, and two light-emitting elements on the adjacent light-emitting sides of the light-emitting element corresponding to the height of the gap position between the aforementioned light-emitting elements constitute the right two colors of the sub-pixel module. Since each light-emitting element rotates at a uniform speed in the track, the light radiation direction of each unit in its sub-pixel module can reach different viewing positions around the track through rotation, and be captured by human eyes at different viewing positions, thereby achieving the same pattern output effect at different viewing positions.

[0046] Figure 3 It is a cross-sectional schematic diagram of the display unit 1, wherein the cathode 102 and the anode 101 of each pixel unit are electrically connected to the electrode interface at the outer edge of the top end surface of the display unit 1 by a conductive circuit embedded in the assembly, and the cathode and the anode are respectively abutted against each electrode driving port in the clamping area of ​​the track 2 during the rotation of the display unit to form a driving path corresponding to each pixel unit, driving the corresponding display unit to excite the corresponding display light to realize display output.

[0047] In order to ensure that the electrical connection path of the electrode structure between the display unit and the track is stable, the present application preferably passes Figure 4In the manner shown, the drive track 2 is arranged as an inner and outer layer, the top of the inner prism assembly or the curved prism assembly in the display unit 1 extends beyond the top of the outer prism assembly or the curved prism assembly, and the tops of the inner and outer assemblies are respectively arranged with outward flips.

[0048] Thus, the bottom of the inner rail 20 is extended downward and bent inward, so that it can abut against the flip position of the top of the inner prism assembly or the curved prism assembly; similarly, the bottom of the outer rail 22 is extended downward to cover the inner rail 20 and then bent inward, so that it can stably abut against the flip position of the top of the outer prism assembly or the curved prism assembly;

[0049] The above structure cooperates with the negative electrode interface 12 extending from the cathode 102 conductive circuit embedded in the assembly and provided at the flip position of the top of the outer prism assembly or the curved prism assembly, and the positive electrode interface 13 extending from the anode 101 conductive circuit embedded in the assembly and provided at the flip position of the top of the inner prism assembly or the curved prism assembly, and can realize electrical connection with the positive electrode interface 13 through the positive electrode driving port 23 provided on the bent end of the inner track 20, and feed the driving signal of the light-emitting unit into its anode 101; similarly, through the negative electrode driving port 21 provided at the bent end of the outer track 22, realize electrical connection with the negative electrode interface 12, complete the model path of the cathode feeding circuit of the light-emitting unit, realize the excitation of the emission layer and the conductive layer between the cathode and the cathode, so that it radiates the corresponding light waves outward to realize the corresponding color output.

[0050] In order to reduce the occlusion of the background behind the track by the long strip structure of the display unit, the present application preferably uses a transparent flexible polymer material for its prism assembly or curved prism assembly, and correspondingly uses a polyfluorene material as the emitting layer embedded between the inner and outer layers of the flexible polymer, and sets the conductive layer to a polyaniline material, and sets the anode or cathode to a metal film and / or indium tin oxide. The display unit made of flexible polymer material can reduce the occlusion of the background through its transparent structure on the one hand, and can also interact with the human viewer through the flexibility of its material on the other hand. For example, while the pattern content in the corresponding area is synchronized through the reciprocating operation of the display unit, the display unit can be pushed aside by the touch of the viewer, so that the viewer can integrate into the pattern and realize the interaction between virtual and real scenes.

[0051] During this interaction, since the display unit will receive the torque of manual shifting, in order to avoid the misalignment of the docking relationship of its top electrode structure, the present application also preferably sets a positioning rib between each adjacent electrode drive port in the track; and correspondingly, a positioning groove matching the width of the aforementioned positioning rib is set between each adjacent electrode drive port on the reality unit. During the operation of the display unit in the track, its positioning grooves are meshed with the positioning ribs between the electrode drive ports in turn, ensuring one-to-one docking between the electrode drive port and the electrode structure, forming a stable electrical path, and realizing the feeding of the driving current to the corresponding light-emitting element in the reality unit, so that it outputs light of the corresponding color to achieve the imaging effect.

[0052] For the display requirements of a wider format range, the present application can be realized by adding several synchronously running display units 1 in the driving track 2. When running multiple display units, the spacing distance between each display unit in the track remains consistent and the spacing distance between adjacent display units is set to an integer multiple of the circumference of the bottom surface of a display unit through the corresponding relationship between the aforementioned positioning grooves and positioning ribs. For example, the track is divided into three equal-length ABC sections, each of which is connected at the end, and each section corresponds to a display unit. During the display process, the display unit in each track moves in the track from left to right by rotating, and the afterimages of each light-emitting element on the three display surfaces connected end to end in the display unit are mapped to the corresponding positions under the track. As long as the running time of the pixel unit in each track for the track 2 to rotate from the leftmost end to the rightmost end of the track meets the index requirement of refreshing the image of the display area at an update frequency of not less than 960Hz, the afterimage formed by the operation of the display unit along the track can be used to construct a corresponding visual afterimage in the human brain through the visual afterimage effect of the human body, thereby forming a complete image to be displayed.

[0053] For three sections of track with a length of L connected at the end, a display unit runs in each track, and the track distance traveled by the display unit in one rotation is the circumference C of the display unit. Then, the display unit rotates L / C circles in the track to complete a refresh of the image displayed in the track area. Therefore, as long as the interval between the display units is kept constant and the operation rate of each display unit is adjusted to at least 960*L / C circles per second in the L-length track area, a complete display pattern can be constructed through the residual image of each light-emitting element during the operation of the display unit, and a dynamic display effect can be achieved. When the number of display units in each section of the L-length track increases, the operation efficiency of the display unit of 960*L / C circles per second is divided by the actual number of display units evenly distributed in the track, so that the same dynamic display effect can be achieved at a slower operation rate.

[0054] The above is only an implementation method of the present application, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application.
