Description
Technical Field
The application relates to the field of self-luminous display, in particular to a flip chip spatial pixel arrangement structure and a display panel device.
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, the requirements for resolution and brightness of display screens are higher and higher, and for a high-resolution display panel, the requirement for the distance between the light-emitting areas of the sub-pixels is lower and lower due to the higher requirement for resolution, however, the higher pixel density (pixel per inch) cannot be obtained due to the packaging manufacturing process limited by COB. The reduced pitch of the red, green and blue sub-pixels can cause color mixing of the sub-pixels with different colors when the sub-pixels are arranged on the substrate, thereby affecting the display effect of the picture. Therefore, the resolution of the LED panel in the prior art needs to be improved.
The inventor finds that the pixel arrangement structure of the existing display panel has insufficient expression capability on curves and oblique lines, is easy to form sawteeth, has obvious pixel graininess visually, and greatly influences the definition of a picture.
In the related art, as shown in fig. 1, in a display screen pixel of the conventional LED-COB, a red sub-pixel, a green sub-pixel, and a blue sub-pixel are combined into an independent pixel, and a distance between adjacent pixels is greater than a distance between sub-pixels inside the pixels, so that the independent pixels are grouped together, so that a single group of pixels has an obvious granular sensation when displaying a picture, and a display effect of a surface light source is lacked. Specifically, in fig. 1, the pixel set is composed of a red sub-pixel, a green sub-pixel and a blue sub-pixel arranged side by side, and the composed pixels can emit white light. However, the distance between two adjacent pixels is much larger than the distance between the inner sub-pixels, which causes a noticeable graininess. The method is difficult to meet the requirements of electronic equipment and high-definition image signal sources on high resolution and high brightness of display screens.
In the second related art, as shown in fig. 2, in the existing LED-COB display screen pixel, one red sub-pixel, two green sub-pixels, and one blue sub-pixel are combined into one independent pixel, and the distance between two adjacent pixels is close to the distance between the sub-pixels inside the pixels, so the display uniformity of the product can be improved by the scheme, but the cost of the display product cannot be increased due to the increase of the cost of one sub-pixel, and in this case, the cost is relatively high, and in addition, the difficulty of color mixture ratio occurs in color mixture.
Disclosure of Invention
In order to improve the pixel density of the display panel and reduce the pixel granular sensation, the application provides a flip chip spatial pixel arrangement structure and a display panel device.
In a first 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 is used in the field of micro-LED or mini-LED self-luminous display, and comprises a plurality of first pixel sets and a plurality of second pixel sets, the first pixel set comprises a plurality of A pixels which are continuously arranged, 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 sub-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 sets, so that the arrangement rule of the first pixel set, the second pixel set and the first pixel set is presented in the transverse direction, compared with the related art I, the plurality of 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 or even the same, so that the graininess 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, compared with the first related technology, 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, expressive force on curves and oblique lines is improved, and color cross phenomenon among the pixels is reduced while pixel density is improved.
In the first related art and the second 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 this scheme, five independent light-emitting points in the second pixel set are driven by a set of drivers (three drivers) so that the second pixel set can continuously emit white light for multiple times, thereby prolonging the light-emitting period. 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. If an arrangement method similar to that of the related art one is adopted, a significant color difference will occur after a long-term use. 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, the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel of the second pixel set located above and the second sub-pixel and the third sub-pixel of the second pixel set located below form a regular hexagon structure, four sub-pixels at the lower part of the regular hexagon structure and an a pixel at the center of the regular hexagon structure cooperate 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.
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 triple white light, and the adjacent second pixel set can also emit triple 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.
Optionally, four sub-pixels of the lower part of the regular hexagon structure are divided into two matching pairs according to left and right, the matching pairs and the first pixels on the adjacent recombination positions are matched to form a third recombination white light spot, and the second pixel sets are adjacent to each other and respectively control the on-off of the pixels inside the second pixel sets and control the on-off of the first pixels inside the first pixel sets to control the on-off of the third recombination white light spot.
Through adopting above-mentioned technical scheme, the first pixel on the reorganization position not only can be to forming first reorganization white light spot with the reorganization, can also be to forming third reorganization white light spot with the cooperation for the pixel is arranged more evenly, avoids visual pixel graininess, also obtains higher pixel density, and then improves the resolution ratio of panel.
In conclusion, the sub-pixel ratio of each white light spot in the scheme is 1:1:1, and the color mixing is uniform.
Optionally, a complementary color bit is disposed between the recombination bits at the edge of the pixel arrangement structure, a third pixel set is disposed on the complementary color bit, the third pixel set includes a complementary color sub-pixel, the complementary color sub-pixel is a second pixel or a third pixel, the complementary color bit is opposite to the adjacent first sub-pixel or fourth sub-pixel, the complementary color bit opposite to the second pixel is used for installing a complementary color sub-pixel of which the type is a third pixel, and the complementary color bit opposite to the third pixel is used for installing a complementary color sub-pixel of which the type is a second pixel.
By adopting the technical scheme, for the Liquid Crystal Display (LCD), when a straight line is displayed, the edge of the straight line generates a pure color line, for example, for FIG. 1, the top edge of the screen generates a blue line, and the bottom edge generates a red line. Similarly, the delta arrangement in the east of Beijing also easily causes this phenomenon, while the diamond arrangement does not generate a single color sub-pixel in any straight line, but since the OLED has a characteristic of easy burn-in, the areas of the blue sub-pixel and the red sub-pixel are set to be correspondingly larger, and thus color fringing is also easily generated. In the scheme, the second pixel set and the third pixel set are arranged on the same line at the edge of the screen, and the sub-pixels on the complementary color position and the three adjacent sub-pixels form two white light emitting points, so that the phenomenon that the edge generates color lines is relieved.
The application field of the scheme is the field of mini-LED or micro-LED, and the scheme cannot be adopted to relieve the phenomenon that color lines are generated at the edge of the screen in the field of LCD. The LCD adopts a scheme of filtering a white backlight to obtain a desired color, and the concept of color mixing and filtering is different from that of the scheme. In the field, an LED belongs to a point-surface light source, emits direct light outwards and is visible in all directions, an LCD is a surface light source which is generated after backlight or side incident light passes through a light guide sheet, a brightness enhancement sheet, a polarizer and liquid crystal, the direction of the emergent light is determined, and the visible range is relatively small. Therefore, in the scheme, the distance between the adjacent first pixels in the first pixel set at the edge of the screen is greater than the distance between the central sub-pixel and the adjacent sub-pixel, so that the generated single color edge is less obvious, and the filter cannot do the same, so that the generated single color edge is more obvious.
Optionally, the first pixel is a red light sub-pixel, the second pixel is a blue light sub-pixel, and the third pixel is a green light sub-pixel;
optionally, the first pixel is a red light sub-pixel, the second pixel is a green light sub-pixel, and the third pixel is a blue light sub-pixel;

In a second aspect, the present application provides a display panel device, which adopts the following technical solutions:
the utility model provides a display panel device, includes the display panel that Micro Mini type red, green, blue LED flip chip that adopts PCB base plate or glass substrate COB encapsulation to form constitutes, be provided with foretell pixel arrangement structure on the display panel.

Detailed Description
The present application is described in further detail below with reference to figures 3-7.
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. 3, 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 set 1 includes a plurality of a pixels arranged in series, and due to different substrate and product types, in some embodiments, the first pixel set 1 may be arranged in a curve of a single row, in other embodiments, the first pixel set 1 may be arranged in a straight line of a single row, and only two adjacent first pixel sets 1 need to be parallel or overlapped in a translation manner.
Referring to fig. 3 and 4, 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 the extending direction of the first pixel set 1. The second pixel set 2 includes a central sub-pixel 201 and a first sub-pixel 202, a second sub-pixel 203, a third sub-pixel 204 and a fourth sub-pixel 205 which are distributed on a semicircular arc in sequence with the central sub-pixel 201 as a circle center, and the central sub-pixel 201, the first sub-pixel 202, the second sub-pixel 203, the third sub-pixel 204 and the fourth sub-pixel 205 are a pixel a, a pixel b, a pixel c, a pixel b and a pixel c respectively.
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. 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 sub-pixel on the corresponding semi-circular 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. 3 and 5, 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, the second pixel set and the first pixel set 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 of the pairs of recombination groups can cooperate with the pixels of the adjacent first pixel set 1 to form a first recombined white light spot 302, that is, an additional sub-pixel point is added to obtain at least one white light spot, which is beneficial to improving the pixel density and reducing the power consumption of the whole panel compared with the related art.
For any two second pixel sets 2 adjacent up and down, their relative distances 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 first pixel at the center of the regular hexagon structure to form three second recombined white light 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 pixels in the first pixel set 1 are also controlled by driving to control the on/off and luminous intensity of the recombined white light spots in coordination with the driving of the second pixel set 2.
Referring to fig. 6, 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.
In order to reduce the phenomenon of single color edge of the pixel arrangement, referring to fig. 7, in some embodiments, complementary color bits are disposed between the recombination bits at the edge of the pixel arrangement, a third pixel set 4 is disposed on the complementary color bits, the third pixel set 4 includes complementary color sub-pixels 401, and the complementary color sub-pixels 401 are b pixels or c pixels. The complementary color bit is opposite to the adjacent first sub-pixel 202 or fourth sub-pixel 205, the complementary color bit opposite to the second sub-pixel is used for installing the complementary color sub-pixel 401 with the type of C pixel, and the complementary color bit opposite to the C pixel is used for installing the complementary color sub-pixel 401 with the type of B pixel. At the edge of the screen, the second pixel set 2 and the third pixel set 4 are arranged in the same line, and the complementary color sub-pixel 401 on the complementary color position and the adjacent three sub-pixels form two white light emitting points, so that the phenomenon that the edge generates color lines is relieved.
The application field of the scheme is the field of mini-LED or micro-LED, and the scheme cannot be adopted to relieve the phenomenon that color lines are generated at the edge of the screen in the field of LCD. The LCD adopts a scheme of filtering a white backlight to obtain a desired color, and the concept of color mixing and filtering is different from that of the scheme. In the field, an LED belongs to a point-surface light source, emits direct light outwards and is visible in all directions, while an LCD is a surface light source which is generated after backlight or side incident light passes through a light guide sheet, a brightness enhancement sheet, a polaroid, a liquid crystal and a polaroid, the direction of emergent light is determined, and the visible range is relatively small. Therefore, in the present scheme, the distance between the adjacent first pixels in the first pixel set 1 at the edge of the screen is greater than the distance between the central sub-pixel 201 and the adjacent sub-pixel, and the generated single color edge is less obvious, but the filter cannot do so, and the generated single color edge will be more obvious.
The embodiment of the application also discloses a display panel device, including the display panel that Micro/Mini type red, green, blue LED flip chip that adopts PCB base plate or glass substrate COB encapsulation to form constitutes, be provided with on the display panel like above-mentioned pixel arrangement structure.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
