Patent number: 10845011Abstract: A system of lighting for an artificial tree or other decoration that allows easy replacement of small sub-strings of luminaries. Each sub-string contains N luminaries, where N is an integer around 10, where the N luminaries are wired in series. Extender cables can be supplied that contain parallel splits so that the different sub-strings are operated in parallel. The extender cable can attach to a master power source that supplies the constant voltage needed to power each sub-string. The exact voltage is determined by the number N and by the voltage requirement for each of the luminaries. Each sub-string has a plug that mates with a receptacle on either an extender cable, or on the master power device. Single point failures only cause one sub-string to go dark. The physical arrangement with plugs and receptacles allows easy replacement of an individual sub-string that is dark because of a failed luminary.Type: GrantFiled: December 25, 2018Date of Patent: November 24, 2020Assignee: Evergreen Tree LimitedInventor: Cheng-che Tsai

Patent number: 10504460Abstract: The display device includes a circuit and multiple pixels. Each pixel includes multiple sub-pixels, and each sub-pixel includes a pixel electrode and a portion of a common electrode. A frame period includes a first polarity period and a second polarity period. The circuit maintains a voltage of the common electrode unchanged during the frame period, and applies a first dot inversion mode in the first polarity period and applies a second dot inversion mode in the second polarity period to the pixel electrodes. If determining that the input image has a bright stripe and the dark stripe adjacent to the each other, the circuit increases an intensity of the sub-pixel in an edge of the dark stripe or the bright stripe, and/or decrease an intensity of the middle sub-pixel in the bright stripe.Type: GrantFiled: December 14, 2017Date of Patent: December 10, 2019Assignee: HIMAX TECHNOLOGIES LIMITEDInventors: Tung-Ying Wu, Yi-Hsiu Lin, Cheng-Che Tsai, Ming-Hung Weng

Patent number: 9184539Abstract: 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.Type: GrantFiled: June 16, 2014Date of Patent: November 10, 2015Assignee: Evergreen Tree LimitedInventor: Cheng-Che Tsai
