DISPLAY PANEL DRIVING APPARATUS, METHOD OF DRIVING DISPLAY PANEL USING THE SAME AND DISPLAY APPARATUS HAVING THE SAME
Abstract:
A display panel driving apparatus includes a data driving part, a data driving part and an off voltage controlling part. The data driving part is configured to output a data signal to a data line of a display panel. The gate driving part is configured to output a gate signal to a gate line of the display panel. The off voltage controlling part is configured to receive a first off voltage and a second off voltage applied to the gate driving part to generate the gate signal, measure a leakage current of the gate driving part, and control the first off voltage based on the leakage current. Thus, display quality of a display apparatus including the gate driving part may be improved.
Abstract(Chinese):

显示面板驱动装置包括数据驱动部分，数据驱动部分和截止电压控制部分。 数据驱动部被配置为将数据信号输出到显示面板的数据线。 栅极驱动部件被配置为将栅极信号输出到显示面板的栅极线。 关断电压控制部被配置为接收施加到栅极驱动部分的第一截止电压和第二截止电压以产生栅极信号，测量栅极驱动部分的漏电流，并且基于泄漏来控制第一关断电压 当前。 因此，可以提高包括栅极驱动部分的显示装置的显示质量。
