摘要： A charge pump circuit of a liquid crystal display driver integrated circuit (LDI) is provided, which can reduce unnecessary current consumption when a load of an output node varies is provided, where, in a gradient mode of a display-on mode, in which an output node of the charge pump circuit has a maximum load, the current driving capability of a driver in the charge pump circuit is increased, and where, in a binary mode, in which the output node of the charge pump circuit has a smaller load than in the gradient mode, the current driving capability of the driver is lower, to prevent unnecessary current consumption caused by too large driving transfer transistors in the driver and to maintain boost efficiency at a proper level.

摘要： Provided is a liquid crystal display panel having gate drivers. The LCD panel includes a gate line shift circuit setting a gate line scanning order such that the gate lines are sequentially scanned in units of n gate lines with k−1 gate lines between each pair of adjacent gate lines in each unit according to an interleaving method in response to a gate line-on signal received from a timing control unit outside the LCD panel, wherein the LCD panel reproduces source data output from a source driver outside the LCD panel in the gate line scanning order set by the gate line shift circuit. The LCD panel inverts the polarity of a common voltage for every unit of n gate lines, instead of every gate line, thereby reducing power consumption. In addition, since every kth gate line is scanned according to the interleaving method, deterioration of image quality such as a flickering phenomenon can be prevented, which is an advantage of a line inversion driving method.

摘要： One embodiment of the present invention provides a system for managing business responsibilities. During operation, the system receives a user request for a business responsibility and forwards the request to a managing entity, thereby allowing the managing entity to approve or deny the request. If the managing entity approves the user's request, the system identifies one or more resources corresponding to the requested business responsibility, and provisions the credentials required to access the identified resources, thereby allowing the user to access the business responsibility without managing the required credentials. The system further notifies the user that the requested business responsibility is accessible. If the managing entity denies the user's request, the system notifies the user that the request is denied.
