Lamp driving device and display apparatus having the same |
摘要 |
A lamp driving device includes first, second, and third voltage converters. The first voltage converter converts a direct current (DC) power voltage to a first pulse voltage. The second voltage converter converts the DC power voltage to a second pulse voltage. The third voltage converter generates a high alternating current (AC) voltage based on the first and second pulse voltages. The lamp driving device generates the high AC voltage without a transformer, so that a manufacturing cost of a display apparatus adopting the lamp driving device may be reduced.
