Abstract: A display device includes a circuit board provided with signal lines, a first and a second panel unit separately attached to the circuit board and each provided with pixels comprising switching elements, and a driving circuit chip mounted on the circuit board and driving the first and the second panel units.

Abstract: A display apparatus includes a display panel, a gate driver, a data driver and a line selection circuit. The display panel including a plurality of gate lines, and a plurality of data lines divided into a plurality of blocks. The gate driver outputs a scan signal that activates the gate lines in sequence. The data driver applies a data signal to the data lines by a unit of blocks during an active period which corresponds to a time when one of the gate lines is activated such that a polarity of data signals of i-th active period is opposite to a polarity of data signals of (i+2)-th period, wherein ‘i’ is a natural number. The line selection circuit differentiates timing for selecting the blocks per the gate lines and applies the data signal to the blocks of the data lines. Therefore, display is enhanced.

Abstract: A display panel for driving a display panel in response to data and gate signals, includes first and second switching sections, a timing control section, a driving voltage generating section, a gate driving section and data driving section. The first switching section switches a source voltage in response to a first switching signal. The timing control section outputs a gate control signal and a data control signal in response to the source voltage. The driving voltage generating section receives the source voltage to output first, second and third driving voltages. The second switching section switches the first, second and third driving voltages. The gate driving section outputs the gate signals in response to the first and second driving voltages. The data driving section outputs the data signals in response to the third driving voltage. The display panel eliminates a noise generated when an electric power is off.
