However, because these pixels PX distributed on the arc edge of the boundary B cross the first display area DA1 and the second display area DA2 with different pixel densities at the same time, and often have independent color points that are difficult to handle, resulting in that human eyes can easily perceive the existence of the boundary B when viewing the conventional display panel 1. In addition, because the first display area DA1 and the second display area DA2 have different pixel densities, but some of the pixels of the two are arranged closely without interval, it is easy to interfere with each other to cause errors during display data calculation.
Therefore, the above-mentioned problems encountered by the prior art need to be further solved.
Therefore, the invention provides a display panel driving method to solve the above-mentioned problems occurred in the prior arts.
An embodiment of the invention is a display panel driving method. In this embodiment, the display panel driving method is used to drive a display panel including a first display area having a first pixel density and a second display area having a second pixel density. The first pixel density is larger than the second pixel density. There are regular linear boundaries connected to each other between the first display area and the second display area. Each regular linear boundary includes at least one vertical segment and/or at least one horizontal segment having a length larger than or equal to that of adjacent pixels in the first display area. The display panel driving method includes steps of: (a) at the regular linear boundaries, driving pixels in alternate rows and/or alternate columns to display along vertical direction and/or horizontal direction; and (b) in the second display area, driving pixels in alternate rows and/or alternate columns to display along vertical direction and/or horizontal direction.
In an embodiment, driving pixels in alternate rows and/or alternate columns to display in the step (a) and the step (b) is to drive pixels with at least an interval of one row of pixels and/or a column of pixels in the first display area.
In an embodiment, the regular linear boundaries include a first regular linear boundary and a second regular linear boundary connected to each other.
In an embodiment, the first regular linear boundary and the second regular linear boundary are straight lines perpendicular to each other.

Compared to the prior arts, when the different display areas of the display panel have different pixel densities, the display panel driving method according to the present invention adopts a regular straight-line border instead of the traditional arc edge design, and passes at the border and in the display area with lower pixel density. The interlaced and/or interlaced driving pixel display method effectively avoids the problem of color dots, color shift, and uneven brightness caused by the traditional display panel at the junction of two display areas with different pixel densities, which may cause the two display areas to not be visually integrated. It greatly enhances the visual experience of the human eye, and can also avoid the phenomenon of mutual interference during display data calculation.
The advantage and spirit of the invention may be understood by the following detailed descriptions together with the appended drawings.
Reference will now be made in detail to the exemplary embodiments, the same or similar reference numbers or components used in the drawings and the embodiments are used to represent the same or similar parts.
An embodiment of the invention is a display panel driving method. In this embodiment, the display panel driving method is used to drive a display panel.

Step S10: providing a display panel, the first pixel density of its first display area is greater than the second pixel density of its second display area, and there is a plurality of regular linear boundaries connected to each other between the first display area and the second display area, wherein each regular linear boundary includes at least one vertical line segment and/or at least one horizontal line segment, and the length of the at least one vertical line segment/the at least one horizontal line segment is greater than or equal to the length of two adjacent pixels in the first display area;
Step S12: at the plurality of regular linear boundaries, driving pixels to display in alternate rows and/or alternate columns along the vertical direction and/or the horizontal direction; and
Step S14: in the second display area, driving pixels to display in alternate rows and/or alternate columns along the vertical direction and/or the horizontal direction.
It should be noted that “driving pixels to display in alternate rows and/or alternate columns” described in the step S12 and the step 14 refers to “driving pixels with at least an interval of one row of pixels and/or a column of pixels in the first display area with a higher pixel density”, so as to avoid driving pixels to display on the regular linear boundaries or positions quite close to the regular linear boundaries, but not limited to this.
In practical applications, the shape of the second display area with lower pixel density can be a polygon formed by one or more rectangles. Please refer to
