Revenue. Revenue for the year ended December 31, 2007 was $134.0 million, an increase of $29.0 million, or 27.6%, from $105.0 million for year ended December 31, 2006. The increase in revenue between the two periods resulted from increased sales of our DC to DC converters of $15.0 million, LCD backlight inverter products of $6.5 million and audio products of $7.5 million. For the year ended December 31, 2007, despite a decline in our average sales price for certain of our units, revenue from our DC to DC converters increased 20.9% due to increased sales of flat panel TVs and other consumer devices. Revenue for our CCFL products, which are a part of our LCD backlight inverter family increased 22.3% due to strength in the notebook market over the same period in 2006. However, given the uncertainty of the outcome of our litigation with O2, we cannot predict the impact that such litigation will have on such revenue in the future. Revenue for our audio amplifier product family increased by 182.8% primarily due to increased demand for new and existing products used in consumer electronic applications.
Revenue for the year ended December 31, 2006 was $105.0 million, an increase of $5.9 million, or 5.9%, over $99.1 million for the year ended December 31, 2005. The increase in revenue primarily resulted from increased sales of our DC to DC converter products, which increased $14.0 million, or 24.2%. The increase in DC to DC products was mainly due to higher sales volumes from existing products used in consumer electronic applications, including TVs and portable DVDs. Revenue from LCD backlight inverter products decreased $8.9 million, or 23.4%, for the year ended December 31, 2006 as compared to the year ended December 31, 2005, primarily due to customer concerns resulting from our lawsuit with O2 and the availability of alternative solutions from parties not involved in the litigation. Revenue for our audio amplifier product family increased $0.8 million, or 26.1%, primarily due to increased demand for existing products used in consumer electronic applications.
Gross Profit. Gross profit as a percentage of revenue, or gross margin, was 63.6% for year ended December 31, 2007 and 63.7% for the year ended December 31, 2006. Our gross margin remained relatively flat year over year. There was a decline in our average sales prices for certain of our mature DC to DC products, which was offset by a shift in product mix and certain production efficiencies at our Chengdu facility.
Gross profit as a percentage of revenue, or gross margin, remained constant at 63.7% for the years ended December 31, 2006 and 2005. In the first half of 2006, we incurred start-up costs for our Chengdu facilities in the amount of $0.8 million; however, due to a change in product mix and efficiencies in test costs resulting from the start-up of our Chengdu operations, we were able to absorb those costs and maintain our margins.
