Problems solved by technology

When the surface layout of the display panel is carried out, different impedance values ​​are often generated due to the uneven length and / or width of the scanning lines and data lines or other factors, and the resulting difference in the resistance-capacitance product value is very large.
Moreover, the display screen will be uneven like a band, which will cause many poor display problems and greatly reduce the display quality of the display panel.

Abstract

Provided are a display driving device and a driving method of a display panel. The display driving device comprises the display panel, a controller and a driving circuit. The display panel is provided with a scanning line and a data line. The controller receives signal adjusting data and generates driving control signals according to the signal adjusting data. The driving circuit adjusts at least one electrical characteristic of provided scanning driving signals and at least one electrical characteristic of provided data driving signals according to the driving control signals, and the scanning driving signals are provided to the scanning line and the data driving signals are provided to the data line. Further, the signal adjusting data are generated according to the resistance value of the scanning line and the resistance value of the data line.

Description

technical field [0001] The present invention relates to a display driving device and a driving method of a display panel, and in particular to a display driving device and a driving method of a display panel capable of adjusting a driving waveform. Background technique [0002] The rapid progress of the multimedia society is mostly benefited from the rapid progress of semiconductor components or display devices. As far as displays are concerned, thin film transistor liquid crystal displays (Thin Film Transistor Liquid Crystal Display, TFT-LCD) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. [0003] Most of the current display panels made on the glass substrate use indium tin oxide (Indium Tin Oxide, ITO) material as the transparent conductive layer. When the surface layout of the display panel is performed, different impedance values ​​ar...
