Abstract

A data driving circuit of a display apparatus is electrically connected with a display panel through a plurality of data lines. A scanning driving circuit is electrically connected with the display panel through a plurality of scanning lines, and is provided with multiple stages of driving units. Each stage of driving unit is provided with a shift control element and a driving element, the shift control element outputs a control signal according to a starting signal, the driving element outputs an output signal to the corresponding scanning line according to the control signal, a first trigger signal and a second trigger signal, and the output signal is used as the starting signal of the next stage of driving unit. At a first second trigger signal and in a blanking time after start of a data output time of the display panel, the time for upward transition of the second trigger signal and the time for downward transition of the first trigger signal at least partially overlap.

Description

technical field [0001] The present invention relates to a display device, in particular to a plane display device with a scanning driving circuit. Background technique [0002] Flat display apparatus (flat display apparatus) has been used in a variety of electronic products due to its advantages of low power consumption, low heat generation, light weight and non-radiation, and has gradually replaced traditional cathode ray tubes (cathode ray tube, CRT) display device. In the manufacturing technology of flat-panel display devices, such as liquid crystal display devices, the technology of manufacturing the components of the scanning driver circuit on the glass substrate by thin film transistor technology to save the cost of the scanning driver IC is called GOP (Gate driver on panel) technology for short. Most of the display devices manufactured by the current GOP technology are double-sided drive type display devices, that is to say, there are a set of GOP circuits (scanning ...

Problems solved by technology

If the voltage difference between the gate and the source is greater than the threshold voltage (Vth) of the driving transistor, that is, Vgs>Vth, the driving transistor will be turned on, resulting in leakage of the pixel voltage, resulting in abnormal display screens (such as bright and dark lines) )Phenomenon

[0007] Therefore, how to provide a display device that can avoid pixel voltage leakage caused by signal coupling and leakage, and then cause abnormal display images has become one of the important issues.
