Abstract

The invention provides a data driving circuit with a data signal multiplexing structure. The data driving circuit also comprises a power line for connecting a power and a second transistor connected to a power supply line. The source electrode of the second transistor is electrically connected to the power supply line. The gate of the second transistor is electrically connected to a control line in a same line. The drain electrode of the second transistor is electrically connected to different signal lines, and the connection points are between the first transistor and a display area. Through connecting a compensation power supply in the signal line, a pixel unit is initialized so as to reduce the influence of a parasitic capacitor in the pixel unit, and thus the response characteristics and display characteristics of an organic light-emitting display device with the application of the data driving circuit is effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a data driving circuit capable of effectively improving the response characteristics of a display device, a driving method thereof, and an organic light-emitting display. Background technique [0002] Flat panel display has the characteristics of complete planarization, lightness, thinness, and power saving. It is an inevitable trend and research focus of image display development. Among various types of flat-panel display devices, since the active matrix organic light-emitting display device (English full name is ActiveMatrixOrganicLightEmittingDisplay, referred to as AMOLED) uses a self-illuminating organic light-emitting diode (English full name is OrganicLightEmittingDiode, referred to as OLED) to display images, it has a short response time. Short, driven by low power consumption, and relatively better in brightness and color purity, organic light-emitting display devices h...
