Description

Technical Field

[0001] This invention relates to the field of LED display technology, and in particular to a secondary pixel arrangement structure, a virtual pixel arrangement structure, and a multiplexing control method. Background Technology

[0002] Currently, there are two main ways to increase display density on LED displays. The first is to increase the number of LED chips per unit area to improve pixel density. This method uses more LED chips, resulting in higher costs, higher circuit density, and more complex wiring and driving. The second method is to use virtual pixel reuse. However, existing virtual pixel reuse methods are limited and have low reuse rates, only achieving 4 or 6 times the number of virtual pixels as real pixels. This does not truly achieve higher pixel density within the same number of LED chips and display area. Furthermore, current virtual pixel structures suffer from inconsistent pixel spacing, leading to poor display quality and difficulties in color matching. Summary of the Invention

[0131] It should be noted that when hour,

[0132] Specifically, such as Figure 4 As shown, Figure 4 A schematic diagram of the virtual pixel arrangement structure reuse control structure in an embodiment of the present invention is shown. As shown in the figure, the light-emitting component in the 3rd row and 4th column is simultaneously reused by the virtual pixel units in the 1st row and 2nd column, the 1st row and 3rd column, the 2nd row and 2nd column, the 2nd row and 3rd column, the 2nd row and 4th column, the 3rd row and 2nd column, the 3rd row and 3rd column, the secondary pixel unit in the 2nd row and 3rd column, the secondary pixel unit in the 2nd row and 4th column, the secondary pixel unit in the 2nd row and 5th column, the secondary pixel unit in the 3rd row and 3rd column, the secondary pixel unit in the 3rd row and 4th column, and the secondary pixel unit in the 3rd row and 5th column. That is, a single group of light-emitting components is simultaneously reused by 13 pixels.

[0133] It should be noted that the driving signals of the three primary colors corresponding to the secondary pixel units in the second row and third column, the second row and fourth column, the second row and fifth column, the third row and third column, the third row and fourth column, and the third row and fifth column are all one-third of the driving signals of the three primary colors corresponding to the virtual pixel units in which they are located.

[0134] Specifically, the secondary pixel unit in the second row and third column has its pixel center at the center of an equilateral triangle. Three light-emitting components of the same primary color are distributed on an arc centered at this pixel center, and any two adjacent light-emitting components form a central angle of 120°. Therefore, the driving signal of a single light-emitting component in the third row and fourth column is one-third of the driving signal of the corresponding three primary colors of the virtual pixel unit in the second row and third column.

[0135] Furthermore, the driving signals for the three primary colors corresponding to the secondary pixel units in the second row and fourth column, the second row and fifth column, the third row and third column, the third row and fourth column, and the third row and fifth column are all one-third of the driving signals for the three primary colors corresponding to the virtual pixel units they belong to.

[0136] Furthermore, the driving signal D(3,4) of the light-emitting component in the 3rd row and 4th column is the driving signal d(1,2) of the three primary colors corresponding to the virtual pixel unit in the 1st row and 2nd column, the driving signal d(1,3) of the three primary colors corresponding to the virtual pixel unit in the 1st row and 3rd column, the driving signal d(2,2) of the three primary colors corresponding to the virtual pixel unit in the 2nd row and 2nd column, the driving signal d(2,3) of the three primary colors corresponding to the virtual pixel unit in the 2nd row and 3rd column, the driving signal d(2,4) of the three primary colors corresponding to the virtual pixel unit in the 2nd row and 4th column, the driving signal d(3,2) of the three primary colors corresponding to the virtual pixel unit in the 3rd row and 2nd column, the driving signal d(3,3) of the three primary colors corresponding to the virtual pixel unit in the 3rd row and 3rd column, and the driving signal of the three primary colors corresponding to the secondary pixel unit in the 2nd row and 3rd column.

The driving signals of the three primary colors corresponding to the secondary pixel unit in the 3rd row and 4th column. The driving signals of the three primary colors corresponding to the secondary pixel unit in the 3rd row and 5th column. The sum is:

[0137]

[0138] when hour, This achieves a 9-fold reuse effect.

[0139] When the light-emitting component displays a red primary color, its driving signal D(R) = 9d(R); when the light-emitting component displays a green primary color, its driving signal D(G) = 9d(G); when the light-emitting component displays a blue primary color, its driving signal D(B) = 9d(B).

[0140] This uses virtual display technology, where each group of light-emitting components can be reused by up to 13 pixel units, achieving a virtual pixel count that is 9 times the number of real pixels. This reduces the cost of light-emitting chips and, with the same number of light-emitting chips, effectively increases the number of display pixels, improves the reuse rate, and achieves a higher pixel density.

[0141] S305. Drive the light-emitting component based on the driving signal of the light-emitting component.

[0142] In one optional implementation of this embodiment, the corresponding light-emitting component is scanned and driven based on the driving signal of the light-emitting component.

[0143] Specifically, the control unit first writes the display data of the first row of light-emitting components to the column drive latch, and then writes the row scan signal of the first row to the row drive latch, selecting and lighting up the first row of light-emitting components. Then, the second row is lit up in the same way, until the last row is lit up, and a complete frame of the picture is displayed. This process is repeated continuously.

[0144] It should be noted that, based on the persistence of vision effect of the human eye, as long as the refresh rate is higher than 50Hz, the image seen by the human eye using virtual pixels is a stable image that fills the entire screen.

[0145] In an optional implementation of this embodiment, the reuse control method in this embodiment is used to reuse and control the virtual pixel arrangement structure in embodiment two. The application of the virtual pixel arrangement structure is not limited to LED display. It can also be used in OLED and LCD. At the same time, it can be implemented using various packaging processes such as IMD, COB, and MIP, making it more versatile.

[0146] In summary, Embodiment 3 of the present invention provides a method for reusing and controlling a virtual pixel arrangement structure. By employing virtual display technology, each group of light-emitting components can be reused by up to 13 pixel units, achieving a virtual pixel count that is 9 times the number of real pixels. This reduces the cost of the light-emitting chip, effectively increases the number of display pixels with the same number of light-emitting chips, improves the reuse rate, achieves a higher pixel density, and results in a better display effect. Furthermore, the virtual pixel spacing is uniform, the distribution is more even, and the display is more realistic and delicate. The method of implementation is diversified, and the applicability is stronger.

The rows are numbered with each row of LEDs as a unit, and the common electrode pins of the LEDs in each row are connected to obtain: A1, A2, A3, ..., Ai. Any group of LEDs within this scanning area can be illuminated by selecting the common electrode pin of the corresponding row and the pin of the corresponding column, allowing for precise control of each group of LEDs.
