Problems solved by technology

Therefore, the distance between the pixel electrode and the data line is increased to correspond to the protruding length of the active layer in order to prevent an increase in parasitic capacitance generated between the pixel electrode and the data line, which would cause the aperture ratio to decrease.

Abstract

A method for detecting a storage voltage, a display apparatus using the storage voltage and a method for driving the display apparatus. The method for detecting the storage voltage includes applying a test voltage to a storage line in a display panel having an active layer disposed between the storage line and a data line while varying the test voltage, the active layer being in an active state or an inactive state according to the test voltage, and detecting the storage voltage corresponding to the test voltage in an inactive state of the active layer. Thus, the display panel is driven by using the detected storage voltage, so that an aperture ratio may be increased and current consumption may be decreased.

Description

technical field [0001] The present invention relates to a method for detecting a stored voltage, a display device using the stored voltage, and a method for driving the display device. More particularly, the present invention relates to a method for detecting a storage voltage applied to a storage line forming a storage capacitor, a display device using the storage voltage, and a method for driving the display device. Background technique [0002] A liquid crystal display (LCD) device is a display picture An image display device includes a display substrate, an opposite substrate facing the display substrate, and a liquid crystal layer disposed between the display substrate and the opposite substrate. [0003] Conventionally, a display substrate includes gate lines, data lines, storage lines, thin film transistors (TFTs), and pixel electrodes formed on a transparent substrate to independently drive a plurality of pixels. The opposite substrate includes a color filter layer...
