Description

Flip chip spatial pixel arrangement structure and display panel device

technical field

The present application relates to the field of self-luminous display, and in particular, to a flip-chip spatial pixel arrangement structure and a display panel device.

Background technique

In flat panel display technology, Micro (Mini) inorganic light emitting diode (LED) displays are widely recognized by the industry for their many advantages, such as lightness and thinness, active light emission, fast response speed, wide viewing angle, rich colors, high brightness, low power consumption, and high and low temperature resistance. It is recognized as the fourth-generation display technology after LCD displays, OLED displays, and LED signage. Therefore, large-size, high-resolution panels can be realized, which is the focus of current research and the development direction of future display technology.

With the development of display technology, people have higher and higher requirements for the resolution and brightness of the display screen. For high-resolution display panels, due to the increased requirements for resolution, the distance between the sub-pixel light-emitting areas is required to be higher. However, limited by the packaging manufacturing process of COB, higher pixel density (pixels per inch) cannot be obtained. Reducing the pitch of the three sub-pixels of red, green and blue will cause the sub-pixels of different colors to mix colors when the sub-pixels are 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 found that the pixel arrangement structure of the existing display panel has insufficient performance for curves and oblique lines, and is prone to jaggies, and has obvious pixel graininess visually, which greatly affects the clarity of the picture.

In the related art, as shown in FIG. 1 , in the existing LED-COB display screen pixels, a red sub-pixel, a green sub-pixel, and a blue sub-pixel are combined into an independent pixel, and the pixels between adjacent pixels are The distance is greater than the distance between the sub-pixels inside the pixel, so the independent pixels are grouped together so that a single group of pixels will have obvious graininess when displaying the picture, and the display effect of the surface light source is lacking. Specifically, in FIG. 1 , the pixel set is composed of a red sub-pixel, a green sub-pixel and a blue sub-pixel 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 will cause obvious graininess. Such a method is difficult to meet the requirements of electronic equipment and high-definition image signal sources for high-resolution and high-brightness display screens.

In related art 2, as shown in FIG. 2, in the existing LED-COB display screen pixels, one red sub-pixel, two green sub-pixels and one blue sub-pixel are combined into one independent pixel, and two adjacent pixels are combined into one independent pixel. The distance between them is close to the distance between the sub-pixels inside the pixel, so this solution can improve the display uniformity of the product, but the cost of the display product cannot increase the pixel density because of the increased cost of one sub-pixel. In this case, the cost is relatively high. In addition, there will be difficulties in color mixing and matching.

SUMMARY OF THE INVENTION

In order to improve the pixel density of the display panel and reduce the graininess of the pixels, the present application provides a flip-chip spatial pixel arrangement structure and a display panel device.

In the first aspect, a flip-chip spatial pixel arrangement structure provided by the present application adopts the following technical solutions:

A flip-chip spatial pixel arrangement structure, used in the field of micro-LED or mini-LED self-luminous display, includes a plurality of first pixel sets and a plurality of second pixel sets, wherein the first pixel sets include consecutively arranged pixel sets. A number of pixels, the second pixel set includes a central sub-pixel and a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel which are centered on the central sub-pixel and are sequentially distributed on a semi-circular 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 pixel, B pixel, C pixel, B pixel, and C pixel, and the A pixel, B pixel and The C pixel is one of the red photon pixel, the green photon pixel and the blue light sub-pixel respectively, and three independent white light points are formed in each of the second pixel sets. Adjacent sub-pixels are cooperatively formed; the second pixel set is located between adjacent first pixel sets, and 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 formed with a recombination bit on the side of the recombination pair away from the central sub-pixel, and the first pixel in the first pixel set is arranged on the recombination bit and cooperates with the adjacent recombination pair to form the first recombination white light spot. , the first pixel set and the second pixel set are both independently electronically controlled to control the on-off sequence and on-off frequency of the independent white light point and the first recombined white light point.

By adopting the above technical solution, a single second pixel set is composed of five sub-pixels, and three independent white light emitting points are formed inside, and each white light emitting point is surrounded by a pixel A, a pixel B and a pixel C, that is, In other words, the three groups of RGB form three white light emitting points, which are generated without the cooperation of the first pixel set, so they are called independent light emitting points. At the same time, each recombination pair can cooperate with the pixels on the adjacent first pixel set to form a first recombined white light point, that is, an additional sub-pixel point is added, and at least one white light point is obtained. In terms of technology two, it is beneficial to the improvement of pixel density and at the same time reduces the power consumption of the entire panel.

The second pixel set is located between adjacent first pixel sets, so the arrangement rule of the first pixel set-second pixel set-first pixel set is presented in the lateral direction. Compared with the related art 1, a plurality of white light points are It is a continuous and uniform arrangement in the horizontal direction, and the spacing between adjacent white light points and the spacing between sub-pixels is of the same magnitude or even the same, which significantly reduces the graininess of the pixels, which can better meet the needs of electronic equipment and high-definition image signals. The source's requirements for high-resolution and high-brightness display screens.

In addition, compared with the related art 1, the sub-pixels of the same type in this solution are staggered and not arranged on the same straight line, which is helpful for the color mixing of pixels within a unit panel size, and improves the expressiveness of curves and oblique lines. This ensures that the pixel density is improved and the cross-color phenomenon between pixels is also reduced.

In the related art 1 and the related art 2, the on-off of each pixel needs to be controlled by a driver, the on-off of the white light point is controlled by the on-off of the sub-pixel, and the sub-pixel is subjected to pulse width modulation (PWM, Pulse- widthmodulation) to control the brightness of the white light point. That is, in the related art, three sub-pixels or four sub-pixels are driven by one driver. In this solution, five independent light-emitting points in the second pixel set are driven by a set of drivers (three drives), so that the second pixel set can continuously emit white light for multiple times, thereby extending the light-emitting period. The first pixel in the first pixel set is also driven and controlled to control the on-off and luminous intensity of the recombined white light point in cooperation with the driving of the second pixel.

For liquid crystal display technology (LCD) or oxide light emitting diode technology (OLED), pixels can be controlled by thin film transistors (TFT, Thin Film Transistor), which are usually made of metal oxides for Control the liquid crystal or light-emitting oxide, which has a thin film structure and is usually located on the optical path. It has a certain light transmittance and has a light opening. That is to say, when the pixels are denser, if the driving volume does not change, The smaller the aperture is. Therefore, the number of drives imposes constraints on the display quality. In this solution, the driver can set the back of the pixel, so the number of drivers does not affect the amount of light passing, and more drivers can be used in the case of high pixel density, thereby improving various display indicators.

In addition, in the oxide light-emitting diode technology (OLED), the diamond arrangement of the RGB sub-pixels and the BOE delta arrangement of the related art are similar on the surface, but there are substantial differences in fact. The diamond arrangement and the BOE delta arrangement are designed to solve the problem that the lifespan of the RGB three-color sub-pixels of the OLED is quite different, which is commonly known as the burn-in problem. If an arrangement method similar to the related art 1 is adopted, obvious chromatic aberration will occur after long-term use. Therefore, the BOE delta arrangement can make the areas of the blue sub-pixels and red sub-pixels with lower lifetimes set larger to compensate for chromatic aberration. Moreover, after adopting the diamond arrangement or BOE delta arrangement, the pixel density will be reduced. In this solution, this arrangement is used to solve the problem of low pixel density. Since the red sub-pixels, green sub-pixels, and blue sub-pixels have similar life spans, pixels A, B, and C are the same as the red sub-pixels. There is no limit to the correspondence between pixels, green sub-pixels, and blue sub-pixels, only one-to-one correspondence is required, that is, there can be six correspondences, which cannot be achieved in diamond arrangement and BOE delta arrangement. Similarly, the setting area of pixel A, pixel B, and pixel C are also close, so a denser arrangement can be achieved, which is also impossible for diamond arrangement and BOE delta arrangement.

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

By adopting the above technical solution, the first sub-pixel, the second sub-pixel and the central sub-pixel form an equilateral triangle, the second sub-pixel, the third sub-pixel and the central sub-pixel form an equilateral triangle, and the third sub-pixel forms an equilateral triangle. , the fourth subpixel and the center subpixel form an equilateral triangle, in other words, if the first subpixel, the second subpixel, the third subpixel, the fourth subpixel, the center subpixel and the first subpixel The pixels are sequentially connected to form an isosceles trapezoid, and the two endpoints of the bottom side of the isosceles trapezoid are the first subpixel and the fourth subpixel, and the two endpoints of the top side are the second subpixel and the third subpixel. Since the recombination pair and the pixel A on the corresponding recombination position are arranged in an equilateral triangle, the independent white light spots and the first recombined white light spots are arranged uniformly, and the spatial pixels will not be distorted compared with other arrangements, or There is no need to adjust the hue position to correct distortion, and no need to control the system for spatial pixel shifting.

Optionally, the second pixel set is longitudinally arranged in a single row between adjacent first pixel sets, and in any two vertically adjacent second pixel sets, the first pixel of the second pixel set located above is the first pixel set. The sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel and the second sub-pixel and the third sub-pixel of the second pixel set located below form a regular hexagonal structure, and the lower part of the regular hexagonal structure The four sub-pixels and the pixel A at the center of the regular hexagonal structure cooperate to form three second recombined white light spots, and two adjacent second pixel sets control the on-off of their own internal pixels respectively to control the second recombined white light spot. On-off sequence and on-off frequency.

By adopting the above technical solution, two adjacent second pixel sets can spatially recombine and emit white light three times. The pixel set of each second recombined white light point is 1R1G1B, the sub-pixel ratio is 1:1:1, and the white light is mixed. 3:6:1. The distance between the white light-emitting points in the horizontal and vertical directions is uniform, and the pixel arrangement is more uniform, avoiding the visual graininess of the pixels. In addition, the second pixel set can not only emit white light three times by itself, but also can emit white light three times with the adjacent second pixel set, so as to obtain a higher pixel density, thereby improving the resolution of the panel, and also improving the drive to a single pixel set. luminous modulation capability.

Optionally, the four sub-pixels in the lower part of the regular hexagonal structure are divided into two matching pairs on the left and right, and the matching pairs cooperate with the first pixel on the adjacent recombination position to form a third reorganized white light spot, and the two adjacent The second pixel set controls the on-off of its own internal pixels respectively, and the first pixel set controls the on-off of its internal first pixel to control the on-off of the third recombined white light point.

By adopting the above technical solution, the recombined upper pixel can not only form the first recombined white light spot with the recombination pair, but also form the third recombined white light spot with the matching pair, which makes the pixel arrangement more uniform and avoids the visual pixel graininess. , and also achieve a higher pixel density, thereby increasing the resolution of the panel.

To sum up, the sub-pixel ratio of each white light point in this scheme is 1:1:1, and the color mixing is uniform.

Optionally, complementary color bits are arranged between the recombination bits at the edge of the pixel arrangement structure, and a third pixel set is arranged on the complementary color bits, and the third pixel set includes complementary color sub-pixels, and the complementary color sub-pixels are: B pixel or C pixel, the complementary color position is opposite to the adjacent first sub-pixel or the fourth sub-pixel, and the complementary color position opposite to the B pixel is used for installing the complementary color sub-pixel of the C pixel, and the complementary color sub-pixel of the C pixel is opposite. The complementary color bits are used to install complementary color sub-pixels of type B pixel.

By adopting the above technical solutions, for liquid crystal display technology (LCD), when displaying straight lines, solid color lines will be generated at the edges. For example, for Figure 1, the top edge of the screen will generate blue lines, and the bottom edge will generate red lines. Similarly, the BOE delta arrangement is also prone to this phenomenon, while the diamond arrangement does not produce sub-pixels of a single color on any straight line. The area is set to be larger accordingly, so color fringing is still prone to occur. In this solution, at the edge of the screen, the second pixel set and the third pixel set are set in line, and the sub-pixels on the complementary color bits will form two white light emitting points with the adjacent three sub-pixels, which alleviates edge generation. The phenomenon of color lines.

Since this solution is applicable to the field of mini-LED or micro-LED, this solution cannot be adopted in the field of LCD to alleviate the phenomenon of color lines at the edge of the screen. The LCD is a scheme that filters the white backlight to obtain the desired color, and the concept of color mixing and filtering is different from this scheme. In this field, LED is a point surface light source, which emits direct light outward and is visible in all directions, while LCD is a surface light source generated by backlight or side-incident light after passing through a light guide film, a light enhancement film, a polarizer, and a liquid crystal. The direction of the outgoing light is determined, and the visible range is relatively small. Therefore, in this solution, the distance between the adjacent 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-pixels, and the resulting single color fringing is even less obvious, and the filter cannot achieve this. At one point, the resulting single color fringing will be more pronounced.

Optionally, the A pixel is a red photon pixel, the B pixel is a blue light sub-pixel, and the C pixel is a green photon pixel;

Optionally, the A pixel is a red photonic pixel, the B pixel is a green photonic pixel, and the C pixel is a blue light sub-pixel;

Optionally, the A pixel is a green photonic pixel, the B pixel is a blue light sub-pixel, and the C pixel is a red photonic pixel.

In the second aspect, a display panel device provided by the present application adopts the following technical solutions:

A display panel device, comprising a display panel composed of Micro/Mini red, green and blue LED flip-chips packaged with a PCB substrate or a glass substrate COB, the display panel is provided with the above-mentioned pixel arrangement structure .

To sum up, the present application includes at least one of the following beneficial technical effects:

1. By changing the arrangement structure of Micro-LED/Mini-LED pixels, this solution makes the white light emitting points formed by RGB sub-pixels more evenly arranged, avoiding the visual pixel graininess, thereby obtaining a higher pixel density, and then Improve the resolution of the panel; at the same time, increase the distance between sub-pixels of different colors, improve the pixel color mixing within the unit panel size, improve the performance of curves and oblique lines The lower density reduces the power consumption of the entire display panel.

2. This solution also reduces the cost compared to the traditional pixel arrangement solution. The physical RGB pixel group is improved through the spatial reorganization of sub-pixels, which reduces the average physical cost of a single group of pixels and effectively improves the cost-effectiveness of the product.

Detailed ways

The present application will be further described in detail below in conjunction with accompanying drawings 3-7.

The embodiment of the present application discloses a flip-chip spatial pixel arrangement structure, and the pixel arrangement structure 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 the driving relationship, including multiple first pixel sets 1 and multiple second pixel sets 2, wherein the first pixel set 1 includes a number of consecutively arranged pixels. Depending on the type of product, in some embodiments, the first pixel set 1 may be arranged in a single row of curves, and in other embodiments, the first pixel set 1 may be arranged in a single row in a straight line, and only two adjacent groups of A pixel set 1 may be parallel to each other or overlapped in translation.

3 and 4 , there are multiple second pixel sets 2 and are disposed between two adjacent first pixel sets 1 . Specifically, each second pixel set 2 is arranged in the extending direction of the first pixel sets 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 centered on the central sub-pixel 201 and are sequentially distributed on a semi-circular arc. , 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 pixel A, pixel B, pixel C, pixel B, and pixel C, respectively.

The A pixel, the B pixel and the C pixel are respectively a kind of the red photon pixel, the green photon pixel and the blue photon sub-pixel. Compared with OLED, the area of red sub-pixel, blue sub-pixel and green sub-pixel is the same, and there is no need to compensate for the increase of the light-emitting area of blue and red sub-pixels, so pixel A, pixel B and pixel C The correspondence with the green sub-pixel, the blue sub-pixel and the red sub-pixel can be selected differently in different embodiments. Specifically, in some embodiments, pixel A is a red photonic pixel, pixel B is a blue photonic pixel, and pixel C is a green photonic pixel; in other embodiments, pixel A is a red photonic pixel, and pixel B is a green photonic pixel , pixel C is a blue sub-pixel; in other embodiments, pixel A is a blue sub-pixel, pixel B is a red photonic pixel, and pixel C is a green photonic pixel; in other embodiments, pixel A is a blue sub-pixel, The B pixel is a green photonic pixel, and the C pixel is a red photonic pixel; in other embodiments, the A pixel is a green photonic pixel, the B pixel is a red photonic pixel, and the C pixel is a blue light sub-pixel; in other embodiments, the A pixel is a blue photonic pixel. The pixel is a green photonic pixel, the B pixel is a blue light sub-pixel, and the C pixel is a red photonic pixel. Without limitation, in this embodiment, the pixel A is a red photonic pixel, the pixel B is a blue photonic pixel, and the pixel C is a green photonic pixel as an example.

The central angle formed by the central sub-pixel 201 and any pair of adjacent sub-pixels on the corresponding semicircular arc may be different. In some embodiments, a 65° central angle or a 55° central angle or other non-60° central angles may be formed. 's central angle. Since the triangle formed by the central sub-pixel 201 and the adjacent pair of sub-pixels on the corresponding semicircular arc is not an equilateral triangle, spatial pixel distortion will occur. In order to correct the distortion, the hue position needs to be adjusted. Perform spatial pixel shifting. In order to reduce the computational complexity of the control system, in some embodiments, the central angle formed by the central sub-pixel 201 and any pair of adjacent sub-pixels on the corresponding semi-circular arc forms a central angle of 60°. That is to say, the first sub-pixel 202, the second sub-pixel 203 and the central sub-pixel 201 form an equilateral triangle, and the second sub-pixel 203, the third sub-pixel 204 and the central sub-pixel 201 form an equilateral triangle, The third sub-pixel 204, the fourth sub-pixel 205 and the central sub-pixel 201 enclose an equilateral triangle. In other words, if the first sub-pixel 202, the second sub-pixel 203, the third sub-pixel 204, the fourth sub-pixel 205, the center sub-pixel 201 and the first sub-pixel 202 are connected in sequence, they will form an isosceles The two end points of the bottom side of the isosceles trapezoid are the first subpixel 202 and the fourth subpixel 205 , and the 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 the independent white light spots 301 are formed by the cooperation between the central sub-pixel 201 and any adjacent sub-pixel on the corresponding semicircular arc. Each white light emitting point is surrounded by a pixel A, a pixel B and a pixel C, that is to say, three groups of RGB form three white light emitting points, which do not need the cooperation of the first pixel set 1 to be generated, so it is called independent Glowing point.

3 and 5 , the first sub-pixel 202 and the second sub-pixel 203, the third sub-pixel 204 and the fourth sub-pixel 205 respectively form a recombination pair, and the pixel arrangement is on the side of the recombination pair away from the center sub-pixel 201. A recombination bit is formed, and the first pixel in the first pixel set 1 is disposed on the recombination bit and cooperates with the adjacent recombination pair to form the first recombined white light spot 302 . Further, the recombination pairs and the A pixels on the corresponding recombination bits are arranged in an equilateral triangle. The arrangement law of the first pixel set - the second pixel set - the first pixel set is presented in the horizontal direction, and the multiple white light points are continuously and uniformly arranged in the horizontal direction. With the same spacing, the graininess of the pixels is significantly reduced, which can better meet the high-resolution and high-brightness requirements of electronic devices and high-definition image signal sources for display screens.

In addition, each recombination pair can cooperate with the pixels on the adjacent first pixel set 1 to form the first recombined white light spot 302, that is to say, an additional sub-pixel point is added, and at least one white light spot is obtained. For the second related art, it is beneficial to increase the pixel density and reduce the power consumption of the entire panel at the same time.

For any two vertically adjacent second pixel sets 2, the relative distance may be different in different embodiments. In order to avoid distortion of spatial pixels, in some embodiments, the upper second pixel set 2 The first sub-pixel 202, the second sub-pixel 203, the third sub-pixel 204 and the fourth sub-pixel 205 and the second sub-pixel 203 and the third sub-pixel 204 of the second pixel set 2 located below form a regular hexagonal structure, And the four sub-pixels at the bottom of the regular hexagonal structure cooperate with the first pixel at the center of the regular hexagonal 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 arranged in a uniform mesh as a whole.

The first pixel set 1 and the second pixel set 2 are both independently electronically controlled to control the on-off sequence and 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 are controlled respectively. The on-off of the internal pixels is used to control the on-off sequence and on-off frequency of the second recombined white light spot 303 . Specifically, the on-off of each pixel needs to be controlled by the driver, the on-off of the white light point is controlled by the on-off of the sub-pixel, and the sub-pixel is subjected to Pulse-width modulation (PWM, Pulse-width modulation) to control the white light Brightness of the point. In this solution, five independent light-emitting points in the second pixel set 2 are driven by a set of drivers, so that the second pixel set 2 can continuously emit white light for many times, thereby extending the light-emitting period. The first pixel in the first pixel set 1 is also driven and controlled, so as to cooperate with the driving of the second pixel set 2 to control the on-off and luminous intensity of the recombined white light point.

6, adjacent sub-pixels of two adjacent second pixel sets 2 are also surrounded by RGB areas to form white light spots. Specifically, the four sub-pixels in the lower part of the above-mentioned regular hexagonal structure are divided into two matching pairs according to left and right, That is, the first sub-pixel 202 of the second pixel set 2 above and the second sub-pixel 203 of the second pixel set 2 below form a matching pair, and the fourth sub-pixel 205 of the second pixel set 2 above and the third sub-pixel below The second sub-pixels 203 of the set of pixels 204 form a mating pair. The coordination pair cooperates with the first pixel on the adjacent recombination position to form a third recombination white light spot 304. The two adjacent second pixel sets 2 control the on-off of their own internal pixels respectively, and cooperate with the first pixel set 1 to control their own internal A pixels. on and off, so as to control the on-off of the third recombined white light spot 304 .

In order to reduce the single color fringing phenomenon that occurs in the pixel arrangement structure, referring to FIG. 7 , in some embodiments, complementary color bits are arranged between the recombination bits at the edge of the pixel arrangement structure, and a third pixel set 4 is arranged 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 the fourth sub-pixel 205, and the complementary color bit opposite to the B pixel is used to install the complementary color sub-pixel 401 of the C pixel type, and the complementary color bit opposite to the C pixel is used to install Complementary color sub-pixel 401 of type B pixel. At the edge of the screen, the second pixel set 2 and the third pixel set 4 are arranged on the same line, and the complementary color sub-pixel 401 on the complementary color position will form two white light emitting points with the adjacent three sub-pixels, which alleviates the generation of color lines at the edge. The phenomenon.

Since this solution is applicable to the field of mini-LED or micro-LED, this solution cannot be adopted in the field of LCD to alleviate the phenomenon of color lines at the edge of the screen. The LCD is a scheme that filters the white backlight to obtain the desired color, and the concept of color mixing and filtering is different from this scheme. In this field, LED is a point-surface light source, which emits direct light outward and is visible in all directions, while LCD is a backlight or side incident light generated after passing through a light guide film, a light enhancement film, a polarizer, a liquid crystal, and a polarizer. Surface light source, the direction of the outgoing light is determined, and the visible range is relatively small. Therefore, in this solution, the distance between the adjacent pixels A 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-pixels, and the resulting single color fringe is even less obvious, and the filter cannot At this point, the single color fringing it produces will be more pronounced.

The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore: all equivalent changes made according to the structure, shape and principle of the present application should be covered within the scope of the present application. Inside.
