Abstract
An organic light emitting diode (OLED) display device includes a display panel including a plurality of pixel rows; a driving circuit configured to: provide a first display data to the plurality of pixel rows in a normal mode; provide a second display data including black data to the plurality of pixel rows in a dimming mode, in response to a mode signal; and decrease a second luminance of the display panel in the dimming mode to a level lower than a first luminance of the display panel in the normal mode; and a power supply configured to apply a lower power supply voltage and a high power supply voltage to the display panel, the power supply providing the mode signal.
Claims20
An organic light emitting diode (OLED) display device, comprising:
- a display panel comprising a plurality of pixel rows;
- a driving circuit configured to:
- provide a first display data to the plurality of pixel rows in a normal mode;
- provide a second display data comprising black data to the plurality of pixel rows in a dimming mode, in response to a mode signal;
- and
- decrease a second luminance of the display panel in the dimming mode to a level lower than a first luminance of the display panel in the normal mode;
- and
- a power supply configured to apply a lower power supply voltage and a high power supply voltage to the display panel, the power supply providing the mode signal.
A display system comprising:
- an application processor configured to generate image data and a control signal;
- an organic light emitting diode (OLED) display device configured to display the image data in response to the control signal;
- and
- a power supply comprising a battery configured to provide a power supply voltage to the OLED display device and a battery sensing module configured to detect a power of the battery,
- wherein the OLED display device comprises:
- a display panel comprising a plurality of pixel rows;
- and
- a driving circuit configured to:
- provide a first display data to the plurality of pixel rows in a normal mode;
- provide a second display data including black data to the plurality of pixel rows in a dimming mode, in response to a mode signal;
- and
- reduce a second luminance of the display panel in the dimming mode to a lower level than a first luminance of the display panel in the normal mode, the mode signal being based on a battery sensing signal that the battery sensing module generates based on the power of the battery.
