Display panel and backlight compensation method therefor

A backlight compensation method for a display panel, the display panel comprising a backlight source configured to provide a light source for the display panel, the backlight compensation method comprising:

• detecting ambient light parameters at four positions of the display panel to obtain an ambient light intensity parameter at a first position, an ambient light intensity parameter at a second position, an ambient light intensity parameter at a third position, and an ambient light intensity parameter at a fourth position, wherein the four positions of the display panel comprise the first position, the second position, the third position, and the fourth position;
• calculating a ratio of the ambient light intensity parameter at the first position to the ambient light intensity parameter at the second position, and adjusting a first preset parameter and a partition parameter in a first direction based on the ratio of the ambient light intensity parameter at the first position to the ambient light intensity parameter at the second position and a respective preset model;
• calculating a ratio of the ambient light intensity parameter at the third position to the ambient light intensity parameter at the fourth position, and adjusting a second preset parameter and a partition parameter in a second direction based on the ratio of the ambient light intensity parameter at the third position to the ambient light intensity parameter at the fourth position and a respective preset model;
• obtaining a partition compensation table for a total number of n*m partitions based on the ambient light intensity parameter at the first position, the ambient light intensity parameter at the second position, the first preset parameter, the partition parameter in the first direction, the ambient light intensity parameter at the third position, the ambient light intensity parameter at the fourth position, the second preset parameter, and the partition parameter in the second direction;
• driving backlight sources of a plurality of different partitions according to the partition compensation table;
• wherein the four positions are respectively four sides of a light-emitting surface of the display panel, wherein the first position and the second position are opposite sides, and wherein the third position and the fourth position are opposite sides, wherein a direction pointing from the first position to the second position is the first direction, the direction pointing from the third position to the fourth position is the second direction, wherein a number of partitions arranged in the first direction is n, and a number of partitions arranged in the second direction is m, and wherein a total number of the plurality of different partitions is n*m;
• wherein the first preset parameter is a ratio of the ambient light intensity parameters between every two adjacent partitions arranged in the first direction, and the second preset parameter is a ratio of the ambient light intensity parameters between every two adjacent partitions arranged in the second direction;
• wherein each of the plurality of different partitions comprises at least one lamp bead, and wherein m and n are natural numbers greater than 0.
