Abstract

The present application proposes a display device and its driving method. The display device includes a display panel and a drive control module. The display panel includes a first display area and a second display area. The drive control module drives the first display area to display The first data signal of the first data signal, and the second data signal for driving the second display area to display, so that the high potential segment of the first data signal is located in the low potential segment of the second data signal, and the second data signal The high potential section of the signal is located in the low potential section of the first data signal, so that the first data signal and the second data signal are arranged out of phase, and the first data signal and the second data signal are avoided. The above-mentioned second data signals are arranged in the same phase, resulting in excessive peak current, which reduces the maximum current required by the display device for display, and also reduces the requirements of the display device for power supply specifications, saving production and use costs.

Description

technical field [0001] The present application relates to the display field, in particular to a display device and a driving method thereof. Background technique [0002] In recent years, Mini-LED (Mini Light Emitting Diode) has been widely used in the backlight of display devices because of its ultra-thin and multi-partition functions. The requirements for effects are getting higher and higher, and Mini-LED will be further used in display panels with high gray scale display. [0003] At present, in order to realize the display of high-gray-scale display screens such as 64 gray-scale, the display panel will be divided into at least two display areas, and two driving integrated circuits (IC, integrated circuit) are correspondingly arranged to drive the two display areas respectively. However, since the two drive ICs use the same phase output mode to drive the display panel, the currents driving the two display areas will be superimposed at the peak value, resulting in a larg...
