Abstract:
The present invention divides a wire supplying a scan start signal to a gate driver into two wires, so as to avoid overlapping a clock signal line. In this way the clock signal is not delayed by interference, and a gate driving margin may continue uninterrupted, thereby uniformly outputting a gate-on voltage. In particular, if the clock signal line is connected to all stages in the gate driver and the clock signal line overlaps the scan start signal line, unsightly horizontal bands appear on the image and the parallel gate lines generate a very large parasitic capacitance. In contrast, the gate drivers in the present disclosure comprise clock signal lines which do not overlap the scan start signal lines. As benefits, interference resulting in horizontal banding is minimized and the power consumption may be reduced by about 10%.
Abstract:
In an array substrate and a display apparatus, a pixel part has a plurality of gate lines, a plurality of data lines, and a plurality of pixels electrically connected to the gate and data lines. A driving circuit drives the pixel part electrically connected to a first end of the gate lines. An inspection circuit is electrically connected to a second end of the gate lines, and inspects the pixel part in response to an inspection signal externally provided. Thus, positions and causes for defects of the pixel part may be accurately detected, thereby improving inspecting efficiency.
Abstract:
A gate driver comprises a shift register that has a plurality of stages connected together and outputs a gate signal comprising a first pulse and a second pulse to a gate line. A stage includes a holding part, a pre-charging part, a pull-up part, and a pull-down part. The holding part discharges an output terminal to an off-voltage in response to a first clock signal. The pre-charging part turns off the holding part and outputs the first clock signal as the first pulse to the output terminal in response to an output signal of a previous stage. The pull-up part outputs a second clock signal as the second pulse to the output terminal in response to the output signal of the previous stage. The pull-down part discharges the first output terminal to the off-voltage in response to an output signal of a next stage.
Abstract:
A laundry treatment apparatus is provided that includes a condensing pool disposed within a water supply port formed in a tub, a water supply passage formed between the condensing pool and the water supply port, and a cap that guides water to the condensing pool and stops steam flowing backward through the water supply passage so that the steam is introduced into the condensing pool. The steam flowing backward from an inside of the tub to the water supply port of the tub is brought into contact with the water contained in the condensing pool and is condensed, thereby preventing pollution of a detergent holder or peripheral portions thereof, which may occur when the steam flows backward into the detergent holder or peripheral portions thereof via the water supply port of the tub.
