Detailed Description
The present disclosure will be described in more detail below with reference to the accompanying drawings. Like elements in the various figures are denoted by like reference numerals. For purposes of clarity, the various features in the drawings are not necessarily drawn to scale. In addition, certain well known components may not be shown.
FIG. 2 is a schematic diagram of an LED display screen according to an embodiment of the present disclosure. As shown in fig. 2, the display panel 200 includes a plurality of rows (Row 1-Row 10) and a plurality of columns (P1-P10) of subpixels r, g, b, and is connected to an external display integrated chip (not shown) via Row lines and column lines. The sub-pixels r, g and b respectively correspond to red light, green light and blue light LED lamps. As shown in the figure, the edge position of the display panel 200 is manufactured with a special-shaped portion in units of sub-pixels to realize an arc of the edge. For example, the ROW1 starts with the sub-pixel b of column P3 and ends with the sub-pixel r of column P8. That is, the sub-pixels r and g in the P3 column of the first Row1 are cut out, the sub-pixels g and b in the P8 column of the first Row1 are cut out, and so on. A smoother arc can be obtained by making the odd-shaped portion in units of sub-pixels.
Fig. 3a and 3b are schematic views of rounded corners fabricated in units of pixels and sub-pixels, respectively, on a display screen according to an embodiment of the present disclosure. As is apparent from the figure, the rounded corners made in sub-pixel units have smoother edge arcs than the rounded corners made in pixel units.
However, in a display panel having an irregular portion manufactured in units of sub-pixels, since the pixel units at the edge are not complete, color leakage occurs at the edge of the display panel when data is displayed. Illustrated in an RGB encoding format. The pixel unit of an edge includes only sub-pixels r and g, that is, the sub-pixel b is cut off, and the pixel value to be displayed on the pixel unit is (r ', g', b '), the pixel value b' cannot be displayed, and the last displayed (r ', g', 0), that is, the pixel data finally displayed on the pixel unit is different from the pixel data desired to be displayed, with the result that the pixel data of the point is more abrupt, and the edge color leakage problem is generated.
In order to solve the problem of color leakage of the edge of the special-shaped part of the display screen, the border data of the special-shaped part of the display screen is recorded into a register in the design stage of the display screen. The boundary data of the shaped portion indicates a boundary position of the shaped portion and a sub-pixel at the boundary position.
For example, for the above-described display screen 200, the boundary data of the recorded abnormal portion is as shown in table 1. In table 1, the start position indicates the start position and the start sub-pixel of each row of pixels of the display screen, and the end position indicates the end position and the end sub-pixel of each row of pixels of the display screen.

| Starting position | Stop position | |
| Row1 | b of P3 | r of P8 |
| Row2 | g of P2 | b of P9 |
| Row3 | b of P1 | r of P10 |
| Row4 | g of P1 | g of P10 |
| Row5 | P1 | P10 |
| Row6 | P1 | P10 |
| Row7 | g of P1 | g of P10 |
| Row8 | b of P1 | r of P10 |
| Row9 | g of P2 | b of P9 |
| Row10 | b of P3 | r of P8 |
According to the embodiment of the present disclosure, when the display data is displayed on the display screen, the pixel position of the pixel data of the display data needs to be compared with the data of the upper table, the pixel data corresponding to the boundary position of the special-shaped portion is found, and the pixel data is adjusted.
Fig. 4 is a flowchart of a driving method of a display panel according to an embodiment of the present disclosure. The display screen comprises a shaped portion at the border location.
The driving method includes the following steps.
In step S401, display data is received.
The display Data (Image Data) is a set of gradation values of each pixel (pixel) expressed as a numerical value. The display data includes a plurality of pixel data corresponding to each pixel, the pixel data including a pixel position and a pixel value (gradation value). At present, the mainstream image coding formats include RGB and YUV, and on the basis, other coding formats are further derived.
In step S402, the pixel position of the pixel data is compared with the boundary data of the pre-stored abnormal-shaped part.
From the display data obtained in step S401, each pixel position is matched with the boundary data (data in table 1) of the pre-stored irregularly shaped part, and pixel data corresponding to the boundary position of the irregularly shaped part can be found. The boundary data of the abnormal portion may be recorded at the time of designing the display panel and stored in a register of the display panel driving IC.
In step S403, it is determined whether the pixel position of the pixel data and the boundary data of the special-shaped portion match.
If the pixel position of one pixel data corresponds to the boundary data of the special-shaped part, step S404 is executed, i.e. the pixel data corresponding to the pixel position is adjusted by using the algorithm. If the pixel position of one pixel data does not correspond to the boundary data of the abnormal portion, step S405 is performed, i.e., no processing is performed on the pixel data corresponding to the pixel position.
In step S404, pixel data in which the pixel position matches the boundary data of the irregularly shaped part is adjusted.
The purpose of adjusting the pixel data matching the pixel position and the boundary data of the abnormal portion is to prevent the pixel data matching the boundary data of the abnormal portion from protruding from the peripheral pixel data and causing a color leakage problem. To this end, the pixel data may be adjusted, for example, according to pixel data of neighboring pixels, or directly to a softer color. In a preferred embodiment, this is achieved by reducing the size of the pixel data.
For example, if a pixel at a boundary position on a display screen includes only sub-pixels r and g, the pixel value of the pixel data to be displayed on the pixel is (255,182,193). Then in a preferred embodiment 255 and 182 are divided by a preset value, e.g., 2, and the adjusted value is (255/2,182/2,0), since 193 has no corresponding sub-pixel to directly set it to zero. In another preferred embodiment, a predetermined value, for example, 120, is subtracted from 255 and 182, and the adjusted value is (255-. By reducing the pixel values (i.e., the individual sub-pixel values), the pixel data can be displayed without being so apparent as to be distinguishable from the surrounding pixel data. In addition, the preset value can be adjusted at will according to actual needs.
In step S405, the pixel data is output.
And finally, outputting the adjusted pixel data to a display screen for display.
In summary, the driving method of the display panel provided by the embodiment of the disclosure is suitable for a display panel having an irregular portion manufactured by taking a sub-pixel as a unit. The driving method adjusts the pixel data corresponding to the boundary position of the special-shaped part in the display data according to the boundary data of the special-shaped part of the pre-stored display screen for the input display data, and outputs the adjusted pixel data to the display screen for display, so that the pixel data displayed by the sub-pixels can not be protruded from the peripheral pixel data when the display data is displayed, and the problem of color leakage of the edge of the special-shaped part is solved.

The storage module 503 is used to store the boundary data of the special-shaped portion of the display screen. The boundary data of the shaped portion indicates a boundary position of the shaped portion and a sub-pixel at the boundary position.

Further, the display data is in an RGB format or a YUV format.
Further, the boundary data of the pre-stored irregular portion of the display screen indicates a start position and an end position of each line of pixels of the irregular portion and sub-pixels at the start position and the end position. For example, the boundary data of the shaped portion records boundary information of the display screen, such as a start position, an end position, a start sub-pixel (or start pixel), and an end sub-pixel (or end pixel) of each line of pixels.
