Problems solved by technology

[0002] With the continuous development of science and technology and the continuous improvement of people's living standards, various types of electronic devices with display functions are more and more popular, and more and more electronic devices are equipped with front cameras on the display panel to meet Selfie, video call and other needs, however, in order to install a camera on the display panel, it is necessary to set a hollowed out area on the display panel. In this hollowed out area, there is no driving line, which will affect the line load of the display panel (line load ), resulting in uneven brightness of the display panel

Abstract

The invention relates to a driving device, a driving chip and electronic equipment, the device is used for driving a display panel to emit light, the display panel comprises a plurality of driving lines, and the display panel comprises at least one first display area and at least one second display area, the driving lines connected to the first display area are shorter than the driving lines connected to the second display area, the device comprises a first driving circuit used for outputting a plurality of first target signals through the driving lines connected to the first display area with a preset driving capability, and a second driving circuit used for outputting a plurality of second target signals through the driving lines connected to the second display area, the driving capability represents the speed of outputting the target signal by the driving circuit; the second driving circuit is used for outputting a plurality of second target signals through a driving line connected to the second display area with first driving capacity, and the first driving capacity is larger than the preset driving capacity. According to the embodiment of the invention, the display brightness of each area of the display panel can be homogenized, and the problem of brightness difference caused by load difference is solved.

Description

technical field [0001] The present disclosure relates to the technical field of integrated circuits, and in particular, to a driving device, a driving chip and an electronic device.
