Abstract

The invention relates to a method for operating a display. The method includes the following steps: firstly, an input voltage of the display is detected; when the input voltage declines to a first voltage, the data signal source of the display is cut off with a plurality of data wires, therefore, a plurality of data wires are coupled with each other. After the data wires are coupled with each other, transistors of all pixel units of the display are conducted so that electric potentials at a first end of a plurality of storage capacitances which are coupled with the transistors can be neutralized, and the transistors are coupled with data wires. After the neutralization of the electric potentials at the first end of the storage capacitances, a second end of the storage capacitances is coupled with a ground terminal.

Description

technical field [0001] The invention relates to a display, and in particular to a display capable of improving afterimage after shutdown. Background technique [0002] With the substantial progress of computer performance and the high development of Internet and multimedia technology, the transmission of image information has mostly changed from analog to digital transmission. In order to match the modern life pattern, the volume of video or image devices tends to be thinner and thinner day by day. Flat Panel Display (FPD) developed in conjunction with optoelectronic technology and semiconductor manufacturing technology, such as Liquid Crystal Display (LCD), Organic Electro-Luminescent Display (OELD) or Plasma Display (Plasma Display Panel, PDP), has gradually become the mainstream of display products. [0003] figure 1 It is a partial circuit diagram of an existing display. Please refer to figure 1 , each pixel unit of an existing display includes a transistor 103 , a ...
