Abstract

The invention provides an organic light emitting displayer and a driving method thereof. Voltage resetting is performed on the pixel units of a display area by a reset circuit formed by a first test signal line, a second test signal line and a reset transistor so that the TFT hysteresis effect can be avoided. Meanwhile, the reset circuit is arranged in a non-display area so that the adverse influence on the opening rate and the resolution can be avoided.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to an organic light emitting display and a driving method thereof. Background technique [0002] In recent years, with the rapid development and application of information technology, wireless mobile communication and information home appliances, people's dependence on electronic products is increasing day by day, which brings about the vigorous development of various display technologies and display devices. The flat panel display device has the characteristics of complete planarization, lightness, thinness, power saving, etc., and thus has been widely used. [0003] Among them, an organic light-emitting display is a flat-panel display device that uses an organic light-emitting diode (English full name OrganicLighting Emitting Diode, referred to as OLED) to display images. Thin FilmTransistor liquid crystal display (TFT-LCD for short) has different display methods, no ...
