Abstract
Official abstract text for this publication.
A DC-DC converter and an organic light emitting display including the same are disclosed. The DC-DC converter generates first and second power voltages for the organic light emitting display with an inverting converter and a boost converter. The current of the converters is monitored, and if the currents exceed a threshold, the associated converter is stopped to prevent further damage to the display.
First claim
Opening claim text (preview).
What is claimed is: 1. A DC-DC converter, comprising: a boost converter including a first switching element, a second switching element, and a first inductor; an inverting converter including a third switching element, a fourth switching element, and a second inductor; a switching controller for controlling the first, second, third, and fourth switching elements; and a current sensing unit for sensing an amount of current that flows through the first inductor and for supplyi…
