Abstract: A touch display device is provided, which includes a substrate, multiple touch electrodes arranged in an array on the substrate, and multiple touch lines on the substrate. The touch lines are arranged in a layer different from a layer in which the touch electrodes are positioned. The touch electrodes are arranged corresponding to the touch lines respectively. Each touch line is arranged parallel to a column direction of the touch electrodes. Each touch line includes a signal transmission portion. One end of the signal transmission portion of each touch line is connected to a corresponding one of the touch electrodes, another end of the signal transmission portion of each touch line is extended in a same direction to outside an area where the touch electrodes are positioned. Such configuration reduces a risk of short-circuiting between the touch lines and data lines in the same layer to ensure good production yields.

Abstract: A system is provided to optimize multiple boiler plant systems having mixed condensing and non-condensing boiler groups. The system advantageously employs the independent groups of boilers depending on preset conditions under control of a system control unit. The preset conditions are checked against operating conditions of the boiler plant, and a system control unit controls which of the groups of boilers is the lead and which is secondary. In some instances, both groups of boilers may be utilized under heavy load. Further, effective switching between groups and within groups is also provided to minimize unnecessary repetitive boiler operation.
