Abstract: The present disclosure relates to the field of display technology, and particularly to a display control system and control method, and a display device. The display control system comprises a plurality of source drive chips, a plurality of gate drive chips, a power-on timing controller and a standby timing controller, each of the source drive chips being connected with the power-on timing controller and the standby timing controller, respectively, the power-on timing controller being connected in series with the plurality of gate drive chips, the standby timing controller being also connected in series with the plurality of gate drive chip. The display control system further comprises a backlight source drive chip, both the power-on timing controller and the standby timing controller being connected with the backlight source drive chip. A display of a background-pushed message by a display device in a standby state can be achieved in the present disclosure by employing a design of two timing controllers, the power-on timing controller and the standby timing controller. This solves the problem that existing display devices only enable a prompt of a background-pushed message in the standby state but fail to display the contents of the background-pushed message.
