Abstract
An organic light emitting diode (OLED) display and a low power driving method of the OLED display are provided. The OLED display comprises a display panel that comprises data lines, scan lines intersecting the data lines, and light emitting cells arranged in a matrix form, wherein the light emitting cells respectively comprise OLEDs, a DC-DC converter that is enabled in a normal mode to supply a first high potential power voltage to the display panel and is disabled in a low power mode, and a panel driver that drives the data lines and the scan lines of the display panel, disables the DC-DC converter in the low power mode, and supplies a second high potential power voltage to the display panel.

An organic light emitting diode (OLED) display comprising:
- a display panel that comprises data lines, scan lines intersecting the data lines, and light emitting cells arranged in a matrix form, wherein the light emitting cells respectively comprise OLEDs;
- a DC-DC converter that is enabled in a normal mode to supply a first high potential power voltage to the display panel and is disabled in a low power mode;
- and
- a panel driver that drives the data lines and the scan lines of the display panel, disables the DC-DC converter in the low power mode, and supplies a second high potential power voltage to the display panel,
- wherein the second high potential power voltage is produced in the panel driver.
A low power driving method of an organic light emitting diode (OLED) display comprising a display panel that comprises data lines, scan lines intersecting the data lines, and light emitting cells respectively comprising OLEDs, and a panel driver driving the data lines and the scan lines of the display panel, the method comprising:
- enabling a DC-DC converter in a normal mode to supply a first high potential power voltage produced from the DC-DC converter to the display panel;
- and
- disabling the DC-DC converter in a low power mode to supply a second high potential power voltage produced from the panel driver to the display panel.
