The device comprises a backlight extraction module, a self-adaptive spatial domain filtering module, a self-adaptive time domain filtering module and a backlight enhancement module, wherein the backlight extraction module is used for determining an initial brightness value of each backlight partition of a backlight source based on gray scale information of each image partition of a current frame image; the image partitions and the backlight partitions are in one-to-one correspondence; the self-adaptive spatial domain filtering module is used for carrying out self-adaptive spatial domain filtering on the initial brightness values of the backlight subareas aiming at the backlight subareas to obtain spatial domain filtering values of the backlight subareas; the self-adaptive time domain filtering module is used for carrying out self-adaptive time domain filtering on the spatial domain filtering value to obtain a first ...

Driving method, device and equipment of display panel and computer readable storage medium

The invention discloses a driving method, device and equipment of a display panel and a computer readable storage medium, and relates to the technical field of display. The reference driving voltage of the second display electrode is obtained according to the displayed gray scale of the first display electrode and the to-be-displayed gray scale of the second display electrode, so that the reference driving voltage considers the influence of the first display electrode on the gray scale display effect of the second display electrode. As the position of the second display electrode is related to the corresponding charging delay, the corresponding delay compensation coefficient is obtained according to the position of the second display electrode, and the reference driving voltage is adjusted according to the delay compensation coefficient; the adjusted reference driving voltage is jointly determined according to the displayed gray scale, the to-be-displayed gray scale and the charging delay ...

Regeneration method of reverse osmosis membrane for waste brackish water of thermal power plant

The invention relates to a method for regenerating a reverse osmosis membrane of waste brackish water in a thermal power plant. The method comprises the following steps: chemically cleaning the reverse osmosis membrane; the reverse osmosis membrane is a waste brackish water reverse osmosis membrane which is repeatedly compacted by high hydraulic pressure; and modifying the reverse osmosis membrane of which the internal pollutants are cleaned. The method has the beneficial effects that the modified regenerated membrane obtained by the method can effectively intercept small molecular organic matters and fluorides, has partial salt separation performance and good stability, and has a relatively good practical engineering application prospect.
