Abstract: A liquid crystal display (LCD) and an operating method thereof are provided. The operating method includes the following steps. It is determined whether a first frame and a second frame following the first frame are dynamic frames. When the first frame and the second frame are dynamic frames, a timing controller of the LCD performs a polarity inversion on a polarity signal, so that the polarity signal corresponding to the first frame is the same as the polarity signal corresponding to the second frame. When the second frame is written into an LCD panel of the LCD, energy written into the LCD panel is reduced.

Abstract: A radially uniform spring-biased intra-pole plug connector and transformer outside the trunk configuration for an electric artificial tree is described. The radially uniform plug comprises a springed-tip and a prong, and allows the tree trunk segments to be connected at any point along their 360 degree circumference. The plug connector resembles the structure of a car cigarette lighter. A mold is used to sandwich the plug within the trunk. A plug portion of the plug connector is housed in one trunk segment, and a receptacle portion is housed in a different trunk segment, such that when the trunk segments are assembled, the plug is connected, illuminating the tree. The plug allows the electrical wiring to be hidden and housed within the trunk, providing safety, convenience to the user and giving the tree a cleaner appearance. The transformer outside the trunk configuration makes the trunk safer, more lightweight and less bulky.

Abstract: An umbrella Christmas tree comprising a slide ring, legs pivotably connected to the slide ring and branches rotationally connected to the legs is described. The tree is able to be transformed from a storage position into a continuum of display positions in one motion by sliding a slide ring along the tree trunk, while the legs extend outward increasing the in radius of the base of the tree. Likewise, the transition from a display position to a storage position is accomplished by moving the slide ring in the opposite direction along the tree trunk. These transitions resemble umbrella-like movement. The umbrella tree is pre-embellished with various decorations, including lights and other ornaments, as can be the components of the tree, obviating the need to decorate the tree after it has been set up. The one slide ring design simplifies assembly and disassembly and gives the umbrella tree a neater appearance.

Abstract: A method for operating an electret input device includes the following steps. An input signal is received. It is determined whether a voltage level of the input signal is greater than a first preset value. If the voltage level is greater than the first preset value, the voltage level is compared with a second preset value to determine whether the input signal is an effective signal. If the input signal is the effective signal, the position value of the input signal is obtained. Then, the position value is compared with a preset position value to determine an input state of the electret input device. Finally, the input signal is converted to an output signal to be outputted.
