Abstract: An improved method for detecting a laundry weight in a washing machine employing a sensorless BLDC motor is provided. The motor is rotated until the washer reaches a first speed. The washer then operates in a torque control mode for a predetermined amount of time, and a laundry weight is then determined based on a speed of the motor after the predetermined amount of time has elapsed. In this manner, laundry weight can be accurately determined and the laundry can be effectively washed. Additionally, since a washing machine employing this improved method for detecting does not require a hall sensor and its peripheral circuit manufacture is simplified, and thus cost may be reduced.

Abstract: An LCD is adapted to be manufactured using a significantly reduced number of masks and masking processes. In order to form a gate of the LCD, aluminum and one of molybdenum, tantalum, tungsten and antimony are sequentially deposited and patterned using a single mask. Cutting a shorting bar for preventing static electricity is performed while a passivation layer is patterned and rinsed. Accordingly, an LCD produced by this method includes a first metal layer, which includes a first contact hole and is disposed on a substrate, a second metal layer which covers the first metal layer and includes a second contact hole which is smaller than the first contact hole, an insulating layer, which covers the second metal layer and includes a third contact hole larger than the second contact hole, and a pad, which includes a conductive layer contacting the second metal layer through the third contact hole on the insulating layer.
