Active matrix type organic light-emitting diode panel drive circuit and drive method

Abstract

The invention provides an active matrix type organic light-emitting diode panel drive circuit and drive method. The drive circuit comprises an active matrix type organic light-emitting diode panel (2), a gate driver (4) and a source driver (6) which are in electrical connection with the active matrix type organic light-emitting diode panel (2) separately, and a timing sequence controller (8) and a programmable gamma correction buffer circuit wafer (10) which are in electrical connection with the source driver (6) separately. The timing sequence controller (8) is further in electrical connection with the gate driver (4) and the programmable gamma correction buffer circuit wafer (10) separately. The timing sequence controller (8) is used to control the gate driver (4) through two sets of gate control signals. The source driver (6) is used to provide a data signal to the active matrix type organic light-emitting diode panel (2). The data signal comprises a plurality of date frames. Each of the date frames comprises a plurality of date subframes having a same time.

Description

technical field [0001] The invention relates to the field of flat display, in particular to an active matrix organic light emitting diode panel driving circuit and a driving method. Background technique [0002] The flat panel display device has many advantages such as thin body, power saving, and no radiation, and has been widely used. Existing flat panel display devices mainly include Liquid Crystal Display (LCD) and Organic Electroluminescence Device (OELD), also known as Organic Light Emitting Diode (OLED). [0003] Organic electroluminescent devices have the characteristics of self-luminescence, high brightness, wide viewing angle, high contrast, flexibility, low energy consumption, etc., so they have received extensive attention, and as a new generation of display methods, they have gradually replaced traditional liquid crystal display devices. It is widely used in mobile phone screens, computer monitors, full-color TVs and other fields. Organic electroluminescent de...

Problems solved by technology

Although the driving circuit of this structure is simple in structure, because the second thin film transistor 200 is affected by electrons for a long time, this will affect the threshold voltage V of the second thin film transistor 200. th , which in turn will change the current of the active matrix organic light emitting diode panel, so that the uniformity of the active matrix organic light emitting diode panel is affected, resulting in a decrease in the display quality of the active matrix organic light emitting diode panel
