Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a driving device, a display device and a driving method. The driving device comprises a substrate, a plurality of scanning lines on the substrate, pixel arrays, wherein each pixel array is connected with a corresponding scanning line, each pixel array includes a first pixel unit, a second pixel unit and a switch component connected to the first pixel unit and the second pixel unit, and the conduction of a switch component is controlled by scanning lines such that charge sharing is carried out between the first pixel unit and the second pixel unit. According to the technical scheme of the invention, the charge sharing time is prolonged, the charge sharing is full, and the charge sharing effect is improved.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a driving device, a display device and a driving method. Background technique [0002] Displays with advanced functions have gradually become an important feature of today's consumer electronics products, wherein display devices have been widely used in various electronic devices such as televisions, mobile phones, personal digital assistants (PDAs), and digital cameras. [0003] The display panel of the display device includes a plurality of scan lines and data lines to control charge and discharge of pixel units to display images. When the data line is being driven, its voltage polarity is reversed according to the duty cycle, and the electric energy is continuously consumed during the continuous reversal of the polarity of the data line. To increase the efficiency of power usage, charge sharing can be used to reduce such power consumption. [0004] During cha...
