An air conditioner of present invention comprises a housing having an outer panel forming the exterior and an opening formed on the outer panel, a heat exchanger configured to exchange heat with air flowing into the housing, and a door unit configured to open or close the opening by moving forward or backward from the opening through which the heat exchanged air is discharged. Wherein the door unit comprises a door blade configured to open or close the opening, a door operating part configured to move the door blade forward or backward, and a controller configured to control the air discharged from the opening to be moved forward from the opening in a straight line or to be discharged radially from the opening by controlling a distance between the door blade and the opening.

Air conditioner

A display device includes a display panel having pixels. A timing controller generates a first control signal and data control signals. Data driving circuits each recover a data signal from a corresponding data control signal of the data control signals in response to the first control signal, generate a data voltage corresponding to the data signal, and provide the data voltage to the display panel. Each of the data driving circuits includes: a setting unit configured to acquire a setting value from the data control signal; an equalizer configured to compensate for distortion of the corresponding data control signal according to the setting value to output compensated data control signal; and a recoverer configured to recover a clock signal from the compensated data control signal and recover the data signal from the compensated data control signal based on the clock signal.

Data driving circuit and display device including the same

The present invention relates to a composite material including a porous titania thin film and a preparation method therefor. A composite material according to the present invention allows for a simple thin film formation process because of the use of cellulose crystals, makes it easy to control the structure of the titanium dioxide thin film provided therefor, has a large specific area, and is superior in terms of scratch resistance and photoactivity, thus finding useful applications in the various fields utilizing titanium dioxide as a photocatalyst.

Method for preparing porous titania thin film by using cellulose nanocrystal

An air conditioner according to the present disclosure includes a housing provided with an outer panel forming an appearance, and an opening formed in the outer panel; a heat exchanger configured to exchange heat with air introduced to the inside of the housing; a first discharge portion connected to the opening to discharge heat-exchanged air to the outside; a second discharge portion disposed in a lower side of the first discharge portion in the outer panel to discharge the heat-exchanged air; and a blowing fan disposed inside of the housing to move air, which is heat-exchanged by the heat exchanger, in a direction of the second discharge portion.

A display device and a driving method is disclosed. The driving method includes receiving an image signal for one frame for one pixel, converting the image signal into at least two data voltages according to at least two gamma curves, applying a first gate signal and a second gate signal to a plurality of gate lines respectively connected to a plurality of subpixels included in one pixel during the frame. The method further includes applying the at least two data voltages to the plurality of subpixels during the frame. A gamma curve for the data voltage applied to one subpixel among the plurality of subpixels includes the at least two different gamma curves and is changed with a period of a first time.

Display device using plural gamma curves and driving method thereof

A digital contents control system includes: a set-top box which generates a video for a master display device and a video for a slave display device with a received broadcasting signal and sends the generated videos to the master display device and the slave display device, respectively; the master display device for receiving the video generated for the master display device from the set-top box and displaying the received video; and the slave display device for receiving the video generated for the slave display device from the set-top box, displaying the received video and providing a control video area for control of the master display device or the slave display device to a separate display area, wherein, when a control instruction is input through the control video area provided in the slave display device, the input control instruction is sent to the set-top box and the set-top box controls the video for the master display device or the slave display device according to the input control instruction.
