Abstract
A display device includes: a low drop-out (“LDO”) regulator which provides a second power voltage to a power line during a first period of one frame; a buck converter which provides a first power voltage to the power line during a third period of the one frame; and a pixel connected to the LDO regulator and the buck converter through the power line. A voltage level of the second power voltage is equal to a voltage level of the first power voltage.
Claims20
A display device comprising:
- a low drop-out regulator which provides a second power voltage to a power line during a first period of one frame;
- a buck converter which provides a first power voltage to the power line during a third period of the one frame;
- and
- a pixel connected to the low drop-out regulator and the buck converter through the power line,
- wherein a voltage level of the second power voltage is equal to a voltage level of the first power voltage.
A method of driving a display device including a low drop-out regulator, a buck converter, and a pixel, the method comprising:
- supplying, by the low drop-out regulator, a second power voltage to a power line during a first period of one frame;
- supplying, the buck converter, supplying a first power voltage to the power line during a third period of the one frame;
- and
- receiving, by the pixel, the first power voltage or the second power voltage, which is supplied through the power line,
- wherein a voltage level of the second power voltage is equal to a voltage level of the first power voltage.
