    Abstract: A display driving circuit in accordance with the inventive concepts may include a source amplifier. The source amplifier may include an output transistor configured to amplify an input signal to generate an output signal, and charge a source line of a display panel using the output signal. The source amplifier may include an output transistor switch configured to control the output transistor, and a switch control block configured to receive configuration bits including on/off time information of the output transistor switch to generate a switch control signal. The on/off time information includes information for turning on the output transistor switch in synchronization with a horizontal synchronous signal associated with the display panel, and information for turning off the output transistor switch at a time when the source line of the display panel is charged to a desired charge level.

    Abstract: A water purifier and a filter for the water purifier are provided. The water purifier includes a raw water flow path formed to bring in raw water from the outside, a purified water flow path connected to the raw water flow path for the raw water to flow in a first direction, a filter located in the purified water flow path to filter the raw water, a bypass flow path branched from the purified water flow path for the raw water to bypass the filter and connected to the purified water flow path on a downstream side of the filter in the first direction, a washing flow path branched from the bypass flow path and connected to the purified water flow path on a downstream side of the filter in the first direction, and a drain flow path connected to the filter to guide the raw water flowing into the filter to a second direction. The filter includes a raw water inlet through which raw water flowing in the first direction is introduced, a purified water outlet through which purified water filtered is released, and a drain outlet through which wash water having washed the filter is discharged.
