Abstract: A brightness correcting method of a display panel and a brightness correcting device are disclosed. The method divides a displayed image of the display panel into a first area and a plurality of second areas disposed surrounding the first area. A brightness correction factor of each of the second areas is obtained according to a brightness of the first area and a brightness of each of the second areas. An optical compensation value is adjusted according to the brightness correction factor. The method corrects a brightness of the display panel to allow uniformity of overall brightness of the display panel to meet requirements.

Abstract: A display panel driving method, a display device and a driving device are provided. The method obtains a standard driving voltage value of a target pixel when a subject display content is being displayed and a target compression unit corresponding to the target pixel, determines a target compensation curve parameter from compressed de-Mura data corresponding to the target compression unit according to the standard driving voltage value, determines an effective driving voltage value of the target pixel when the subject content is being displayed according to a position information where the target pixel is in the target compression unit and the target compensation curve parameter, and drives the display panel according to the effective driving voltage. This method could correctly identify the corresponding decompression data and thus the decompressed data could be close to the actual data. This raises the decompression accuracy of decompressing the de-Mura data.

Abstract: A backlight driving method is provided. The method includes: determining a first duration of a first active pulse phase in a backlight driving signal corresponding to a target frame of a to-be displayed picture in a display panel, based on a target duty ratio and a first period corresponding to a target previous frame; wherein the target previous frame is a frame preceding the target frame, and the backlight driving signal is configured to drive a backlight of the display panel; and determining a second duration based on a maximum period corresponding to a frame at a lowest refresh frequency of the display panel and the first period, to delay a start time of the first active pulse phase based on the second duration.
