摘要:
A light guide plate for a surface light-emitting device and a method of manufacturing the same are disclosed wherein the light guide plate is constructed in the form of an optical waveguide including an upper cladding film, core films formed with V-cut grooves, and a lower cladding film, so that since the upper and lower cladding films with a relatively low refractive index are respectively located on upper and lower surfaces of the core films, external foreign substances cannot penetrate into the core films, and the core films are not brought into contact with other components, whereby optical transmission properties are not changed and brightness can be also enhanced, and since the V-cut grooves are formed or both the V-cut grooves and optical waveguides are formed at the same time by means of a simple hot embossing process, the manufacturing costs can be saved.

Provided are a level shifter circuit and a corresponding method for controlling voltage levels of a clock signal and an inverted clock signal for driving gate lines of a ASG thin film transistor liquid crystal display panel, where the level shifter circuit includes first and second level shifters, the first level shifter controls the voltage level of the clock signal to swing between a negative external voltage level and a positive external voltage level in response to a clock activating signal, and increases the voltage level of the clock signal from the negative external voltage level to a power supply voltage level or decreases it from the positive external voltage level to a ground voltage level while a pre-charge clock activating signal is activated, the second level shifter controls the voltage level of the inverted clock signal to swing between the negative external voltage level and the positive external voltage level in response to an inverted clock activating signal, and increases the voltage level of the inverted clock signal from the negative external voltage level to the power supply voltage level or decreases it from the positive external voltage level to the ground voltage level while an inverted pre-charge clock activating signal is activated, and the level shifter circuit increases or decreases the voltage levels of the clock signal and inverted clock signal using a battery voltage or a ground voltage, thereby reducing current consumption caused by the increase or decrease in the voltage level.

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.

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.

A drying machine is disclosed. The drying machine includes a selectively rotatable drum receiving an object to be dried, a steam supply member having one side connected to a steam generator and the other side connected to the drum, and a swirler installed in the steam supply member at a predetermined position for swirling steam flowing through the steam supply member. A method for controlling the drying machine includes heating a drum, supplying steam generated in a steam generator into the drum, and supplying hot air into the drum. The drying machine having the above described configuration can efficiently eliminate creases of clothes.

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.
