A printed circuit board includes a substrate and a plurality of pad forming regions disposed thereon. The plurality of pad forming regions are spaced apart from each other by a predetermined distance. A plurality of connection pads are disposed on a portion of the plurality of pad forming regions. The plurality of connection pads are configured to transmit or receive a signal to an external device or from the external device. The printed circuit board includes a path configured for the transportation of moisture therein.

Printed circuit board and method of manufacturing a printed circuit board

A gate driving module includes a gate driver and a gate signal generator. The gate driver generates a vertical start signal, a plurality of gate clock signals and a plurality of inverse gate clock signals based on a vertical start control signal, a plurality of gate clock control signals, a gate on voltage, a first gate off voltage and a second gate off voltage. The number of the gate clock signals is P. The number of the inverse gate clock signals is P. The number of the gate clock control signals is P. P is a positive integer equal to or greater than two. The gate signal generator generates a gate signal based on the vertical start signal, the gate clock signals and the inverse gate clock signals.

Gate driving module, display apparatus having the same and method of driving display panel using the same

In a method of driving a display panel, a gate signal is outputted to the display panel based on a first control signal. A gamma-corrected analog voltage is generated. A pre-charge compensating analog voltage is generated. A data voltage waveform is generated to include the generated gamma-corrected analog voltage and the generated pre-charge compensating analog voltage during one horizontal period of the display panel. The display panel has a pixel structure in which a data line is alternately connected to first and second subpixel columns adjacent to each other. The pre-charge compensating voltage has a level different from that of the gamma-corrected analog voltage where the latter represents a grayscale level represented by a received digital data signal. According to the method, display defects due to a difference of pre-charging levels used during plural horizontal periods may be decreased so that display quality of the display panel may be improved.
