Wearable device

A display apparatus and a power circuit device thereof are provided. The power circuit device includes: a transforming unit which outputs a first output current and a second output current in response to change of an input current; a first switching unit which switches to allow the input current to be selectively input; a first switch control unit which controls the first switching unit so that an operation voltage of the display apparatus reaches a first target value; a second switching unit which switches to allow the second output current to be selectively output; a backlight driving unit which drives the backlight based on the second output current; and a second switch control unit which controls the second switching unit so that a driving voltage of the backlight reaches a second target value.

Display apparatus and power circuit devices thereof

An image processing apparatus, a power supply apparatus and a circuit apparatus, the image processing apparatus including a display unit which displays thereon an input image, and a power supply unit which outputs direct current power to drive the display unit, but gradually increases a voltage level of the direct current power.

Image processing apparatus and control method thereof for controlling the increase in voltage

A display apparatus, includes: a display unit which displays a video; a light source unit having a plurality of light sources which are independently driven, and which illuminate the display unit; and a driving unit which drives the light source unit. The driving unit includes: a driving signal generating unit which generates a driving signal which has a first voltage level and a second voltage level so that the plurality of light sources can be independently driven, and a control unit which blocks or applies the driving signal to drive the light source unit based on a voltage level which is applied to the light source unit if the driving signal which is generated by the driving signal generating unit is the first voltage level.

Backlight unit and display apparatus having the same
