Abstract: The quantum dot comprises a ligand which is a copolymer comprising a first repeating unit comprising at least one or more hole transporting functional groups and a second repeating unit comprising at least one or more photocrosslinking functional groups.

Abstract: Disclosed is a camera module and a camera apparatus having the same. The camera apparatus includes: a substrate; and a camera module passing through the substrate, and including a lens disposed forward of the substrate and a sensor unit disposed rearward of the substrate. An optical axis is not bent in the camera apparatus so that the accuracy of an image signal is improved.

Abstract: A circuit for variably controlling the frame ratio of a liquid crystal display (LCD) according to an operation mode, and a method for variably controlling the same are provided. A method for displaying received data on a liquid crystal display (LCD) includes the steps of selecting a power save mode, determining whether a data write enable signal for instructing received data to be displayed on an LCD panel is activated, outputting a first frame ratio when the data write enable signal is activated and outputting a second frame ratio when the data write enable signal is deactivated, and displaying the received data on the LCD panel according to the first frame ratio or the second frame ratio. The first frame ratio is larger than the second frame ratio.

Abstract: A liquid crystal display device capable of saving power consumption is provided. The liquid crystal display device reduces the power consumption by decreasing an output voltage of a voltage dividing element thereof and by changing common output signals (alternating current) of a row driver and segment output signals of a column driver make direct current uniformly. In order to achieve the above object, the LCD of this invention includes: a central processing unit for producing data signals when the display device is in on-condition and a power down signal when the display device is in off-condition; a liquid crystal driver controller for receiving an input voltage and divided voltages and for producing an first voltage, segment-output signals and common-output signals when the central processing unit produces the data signals, and for producing a second voltage and direct current voltages when the central processing unit produces the power down signal.
