Embodiment Construction

[0024] A pixel group, a flat display panel, and a driving method for a flat display device according to preferred embodiments of the present invention will be described below with reference to related drawings, wherein the same elements will be denoted by the same reference numerals.

[0025] First, refer to figure 2 As shown, the pixel group 1 used in combination with the pixel group driving method of the present invention has a first display area 11 and a second display area 12, wherein the first display area 11 is coupled to the data line S1 and the first scan line G1, The second display area 12 is coupled to the data line S1 , the first scan line G1 and the second scan line G2 . The so-called "coupling" here is, for example, an electrical connection formed by the transfer of charges. In addition, in this embodiment, the first display area 11 and the second display area 12 can be generally referred to as bright areas and dark areas.

[0026] The first display area 11 has...

Abstract

The invention discloses a driving method for a pixel group. The pixel group comprises a plurality of film transistors, and the plurality of film transistors are electrically connected to a first scanline or a second line and a data line. The pixel group is provided with a first display area and a second display area. The first display area is coupled with the data line and the first scan line. The second display area is coupled with the data line, the first scan line and the second scan line. The driving method comprises the following steps that: in a first time interval, providing a first driving signal by the first scan line, providing a second driving signal by the second scan line to conduct the plurality of film transistors, and writing the pixel data into the first display area andthe second display area of the pixel group through the data line; and in the second time interval, providing a third driving signal by the second scan line to conduct the plurality of film transistorselectrically connected to the second scan line so as to redistribute electric charges at two sides of each film transistor.

Description

technical field [0001] The present invention relates to a driving method, in particular to a driving method for driving a pixel group, a flat display panel and a flat display device. Background technique [0002] Flat Panel Display (FPD), compared with traditional cathode ray tube (Cathode Ray Tube, CRT) display devices, has slim size, light weight, low power consumption, no radiation pollution, and can be combined with semiconductor Advantages such as compatible manufacturing technology have been widely used in various electronic products with display screens. Currently, flat panel display devices include, for example, liquid crystal display devices (Liquid Crystal Display, LCD), plasma display devices (Plasma Display Panel, PDP), organic light emitting diode display devices (Organic Light Emitting Diode display, OLED) according to their structures and operating principles. , Field emission display, Surface conduction Electron Emitter Display (SED), Carbon Nanotube Field E...
