Problems solved by technology

[0004] However, since AMOLED is an active driving method, there will be charge left on the pixel capacitor at the moment of shutdown, and these charges will keep the pixel at the voltage before shutdown at the moment of shutdown, so that the panel will have residual images, forming the so-called shutdown residue. film

Abstract

An array substrate includes: a scanning driving unit for providing a row scanning signal to a plurality of gate lines, and a data driving unit for providing a data signal to a plurality of data lines, the plurality of gate lines and the plurality of data lines being horizontally and vertically crossed to form an array of pixel units arranged in an matrix form, and further including: a control unit electrically connected with the scanning driving unit and the data driving unit respectively, for controlling the scanning driving unit turn on each of the pixel units when the display device is powered off, such that charges stored in the pixel units are rapidly discharged through the data lines, so as to eliminate the shutdown image sticking of the AMOLED display. There have disclosed also a method for driving array substrate and a display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a driving method thereof, and a display device. Background technique [0002] The principle of OLED (Organic Light Emitting Diode) display is to apply a certain electric field to the anode and cathode on both sides of the electroluminescent layer. Driven by the electric field, electrons and holes pass through the cathode and anode respectively. The transport layer and the hole transport layer migrate to the emissive layer, where they meet to form excitons and excite light-emitting molecules, which undergo radiative relaxation to emit visible light. Compared with traditional LCD (Liquid Crystal Display, liquid crystal display), OLED display is more and more used in high performance display field. [0003] According to the driving method, OLED can be divided into two types: PMOLED (Passive Matrix Driving OLED, passive matrix driving organic light emit...
