Abstract: An intelligent control method includes monitoring whether a protected object is within a preset range of a dangerous device. The method includes starting a tracking mode for the protected object when monitoring that the protected object is within the preset range of the dangerous device. The method includes monitoring in real time whether the protected object satisfies a preset condition in the tracking mode, and cutting off a power supply of the dangerous device when the protected object satisfies the preset condition.

Abstract: The present invention discloses a method for repairing a display panel, in which a path for electrically connecting two ends of an opened data line at an opened part thereof is formed by using first line segments and a first common electrode, wherein each of the first line segments is a part of one of common electrode lines in the display panel intersecting the opened data line, and the first common electrode is one of a plurality of common electrodes in a pixel array that is electrically connected with the first line segments. Further, a welding process is performed at an intersecting region between the first line segments and the opened data line to form an electrical connection, and electrical connections between the path and other common electrode lines and other common electrodes outside the path are cut off. This method for repairing data lines employs existing common electrode lines and common electrodes to repair an opened data line, so that no additional repairing line needs to be disposed in the display panel to facilitate a narrow bezel design of the display panel and thus repairing the data lines is no longer limited by the number of the repairing lines. Furthermore, the influence on data signals is negligible because no new line is introduced.
Abstract translation: 本发明公开了一种修复显示面板的方法，其中通过使用第一线段和第一公共电极形成用于电连接开放数据线的开口部分的两端的路径，其中，第一线 片段是与打开的数据线相交的显示面板中的一条公共电极线的一部分，第一公共电极是与第一线段电连接的像素阵列中的多个公共电极之一。 此外，在第一线段和打开的数据线之间的交叉区域进行焊接处理以形成电连接，并且路径和其它公共电极线和路径外的其它公共电极之间的电连接被切断。 用于修复数据线的这种方法使用现有的公共电极线和公共电极来修复打开的数据线，使得不需要在显示面板中设置额外的修理线，以便于显示面板的窄边框设计，从而修复数据 线路不再受修复线路数量的限制。 此外，对数据信号的影响是微不足道的，因为没有引入新的线。

Abstract: A display driving device is disclosed. The display driving device includes: a data signal end for providing a data signal, a source line, and a switching circuit. The source line can transmit the data signal to a first pixel circuit and a second pixel circuit. Along a direction of the source line, a distance between the second pixel circuit and the data signal end is larger than a distance between the first pixel circuit and the data signal end. The switching circuit is between the data signal end and the source line, and can be turned on in response to a first control signal, and can be turned on in response to a second control signal. A turned-on time period of the switching circuit in response to the second control signal is longer than a turned-on time period of the switching circuit in response to the first control signal.
