The present disclosure provides a compound for a display panel. The compound includes elements selected from O, S or N, electron-donor groups and electron-accepting groups. The OLED device in the display panel includes an anode, a cathode, and at least one organic thin film layer between the anode and the cathode. The organic thin film layer includes a light emitting layer, the light emitting layer includes the compound of the present disclosure, and the compound is used to be any one of a host material, a doping material, and a co-doping material. The compound reduces energy level difference between singlet and triplet states &#x394;Ethrough design of the compound molecular structure. The compound realizes an efficient reverse intersystem crossing process, has typical TADF characteristics, and can be used as a light-emitting layer material of an OLED device to improve luminous efficiency and working life.

Compound, a display panel and an electronic device

Provided are a method for driving a display panel, a display driving device and an electronic device. The method includes: acquiring any one frame of the picture to de displayed; dividing the any one frame of the picture to be displayed into a first partition picture, a second partition picture and a third partition picture; displaying the first partition picture in the first display region, displaying the second partition picture in the second display region, and displaying the third partition picture in the third display region; where in a same frame of picture to be displayed, a density Aof sub-pixels for displaying the first partition picture, a density Aof sub-pixels for displaying the second partition picture and a density Aof sub-pixels for displaying the third partition picture satisfy that A&#x2264;A&#x2264;A; and where sub-pixels in the second display region include first sub-pixels and second sub-pixels.

Method for driving a display panel, display driving device and electronic device

Provided are a display panel, a display device and a compensation method for the display device. The display panel includes an organic light-emitting diode display panel and a liquid crystal display panel, where the organic light-emitting diode display panel in a first display region is configured as a backlight for the liquid crystal display panel. The organic light-emitting diode display panel includes a first array substrate and an organic light-emitting function film. The first array substrate includes a first pixel driving circuit, where the first pixel driving circuit includes a first A-type pixel driving circuit and a first B-type pixel driving circuit, and a density of the first A-type pixel driving circuit is less than a density of the first B-type pixel driving circuit.
