Embodiment Construction

[0021] Embodiments of the present invention will be described below with reference to the drawings.

[0022] In the pixel circuit of the present invention, by activating the common gate line after scanning the last gate line, the gap between the first charging gate line connected to the first pixel unit and the last charging gate line connected to the last pixel unit is reduced. The time difference of about one frame between them realizes the simultaneous display of pictures from the first pixel unit to the last pixel unit.

[0023] The present invention provides a full high-definition (FHD) product as an example to illustrate the pixel circuit and its driving method. Each pixel unit has a cache module, a pixel circuit module, a common gate line, a charging gate line, a data line and a common electrode line, such as figure 2 As shown, each pixel unit is connected to a common gate line. Each pixel unit of the pixel circuit includes a buffer module and a pixel circuit module:...
