Hello, everyone. Thank you for joining our call today. COVID-19 indeed change the way we live, work and think. And our team members at MagnaChip have been actively adapting to the new normal by adhering to our multiple safety protocols and business continuity plan. We hope that you and your family are all healthy and well.
We successfully completed the sale of the foundry business and Fab 4, slightly ahead of our internal schedule for a purchase price of about $350.6 million. We used $227.4 million of the proceeds to fully redeem all of the 6.625% senior notes due 2021 on October 2, 2020, lowering the future interest expense by approximately $16 million annually. This sets our new chapter as a fab-lite, pure-play standard product company, generating substantial and sustainable cash flow.
In Q3, we achieved solid quarterly results with a 5% sequential revenue growth, which came in above the high end of the guidance range as well as a healthy bottom line. This was achieved despite the backdrop of market disruptions caused by the global pandemic, the escalated U.S.-China trade tension and supply-constrained environment.
Gross profit margin was largely impacted by 2 onetime items, including the delayed recovery from the power outage of Fab 3 and the display's excess inventory charge related to the U.S. government's export restrictions to Huawei. These 2 onetime items together negatively impacted our gross profit margin by 3 percentage points. Adjusted for the impact of these onetime factors, we delivered non-GAAP diluted earnings per share of $0.14.
Now let's take a look -- closer look at our product business, starting with the display business. I remind you that we have completely exited the non-auto LCD business in Q2 2020. As a reference point, our display revenue in Q3 of 2019 was $90.6 million, which included about $10.4 million of non-automotive LTD business. Our display revenue was $69.6 million for the third quarter, up 0.6% sequentially and down about 14% year-over-year, adjusting the nonautomotive LCD revenue in 2019. Q3 OLED drive IC revenue was $67.6 million, up 0.9% sequentially and down 13.7% year-over-year.
In September, we recorded a $2.3 million excess inventory charge driven by our display customers' last minute business decision based on the U.S. government export restrictions on Huawei. Our panel customers have derisked the Huawei business, and we don't expect further impact from the Huawei ban other than this unusual excess inventory charge. Please note that our Q4 guidance does not include any of Huawei business.
Now let me highlight 3 key takeaways for our display business. First, starting with demand. During our last earnings call, we mentioned an upswing in demand for our OLED product, which was outstripping our supply capability in Q3 due to the recent longer lead times. The strong demand continued throughout the quarter and to date. We are working very closely and diligently with our foundry partners to be able to continue to serve our customers' strong ramp schedule in Q4 and beyond. We remain confident and excited about the long-term growth trajectory of the overall OLED, DDIC market, and our leading market position as one of the pioneers.
Second, both our revenue and design activities were driven by a major Korean smartphone OEM and Chinese OEMs. One of the notable achievements that we are very excited about is that a major Korean smartphone OEM has launched a new key model with our display driver in early October. This end customer's model is being well adapted in the market as it keeps the flagship features that consumers want while hitting the price point that consumers need, and we expect the momentum to continue in the remaining 2020.
In addition, design activities from major Chinese smartphone OEMs have been very strong in Q3, and we expect these design wins to support our revenue growth in Q4 as well as in 2021. MagnaChip's top market position as non-captive supplier in the OLED DDIC market reflects that our advanced technology and distinctive portfolio resonate with our customers. We continue to focus on empowering our customers through relentless innovation and unparalleled support.
Last but not least, the 5G momentum. We are enjoying the booming 5G smartphone industry, especially with our High Frame Rate, HFR, OLED driver ICs. In Q3, we were awarded 8 new design wins, and 7 of them were 5G and HFR models using 28-nanometer process. You may recall that our revenue from 5G smartphones accounted for about 20% of the total OLED revenue in first half 2020. In Q3, 5G revenue represented about 40% of the OLED revenue. According to the market data, the global 5G smartphone shipment in 2020 will be about 200 million units, and it will likely to be more than double in 2021. The emerging global 5G trend bodes well with the underlying strength in our product portfolio.
Now let's turn to the Power business. The Power revenue came in at $46.7 million, up 17.3% sequentially and down 4.2% year-over-year. The complete recovery from the power outage took longer than we anticipated, which limited Fab 3 output at full capacity, resulting in a lower utilization during Q3. Despite this handicap, we achieved a double-digit sequential growth and managed the production. The market momentum and our product pipeline remains strong.
Now let me highlight key takeaways for our Power business. First, starting with demand. As both China and Korea were gradually recovering from the global pandemic, our Power revenue in the third quarter was mainly driven by personal transportation and TV applications. The rebound in Chinese and Korean TV market drove strong demand for our Super Junction MOSFET and Power IC product in Q3, and the trend is continuing in Q4. We expect our Power business in Q4 to grow 15% to 20% year-over-year.
Driven by the combination of capacity constraint and strong demand, our channel inventory level became below our normal operating range. We are striving to address the continued demand and also to replenish the channel inventory to a more balanced level in the future.
Let me also underline the progress we are making in the China market under our go-to-market strategy with a newly established leadership team. To efficiently target the fast-growing China market, we set up a regional support system with a dedicated sales and marketing function. The team focused our product to be more optimized for the China -- Chinese market demand, and we directly engaged with numerous Power customers that resulted in new wins from a wide range of applications, including TV, industrials and mobiles. We are encouraged by the great momentum in China Power business.
Looking ahead, I am very excited about our Power business potential. By 2022, we will have introduced a complete set of next-generation power discrete product portfolios. These new generation premium product families will carry superior performance with a much improved cost. The upgrade will take place at our Fab 3, and by that time, our Fab 3 will be up and running with about 40% additional capacity.
Now turning to our long-term plan. We are repositioning MagnaChip to achieve sustainable and profitable growth. As we close the divestiture ahead of our original schedule, we decided to accelerate our disclosure of pro forma financials rather than wait until the future Analyst Day.
Let me provide our key goals we are targeting to achieve by 2023. While our quarterly reports are based on the total revenue, including the transitional Fab 3 foundry services in accordance with GAAP, we are providing the following metrics based on the standard product business revenue, excluding the transitional Fab 3 foundry service as such service is expected to cease after a certain period of time. We plan to: one, grow our top line at a double digit CAGR; two, consistently achieve above 30% gross profit margin; three, reduced adjusted OpEx to be below 18% of revenue; four, exceed 10% adjusted operating income margin. This will enhance our ability to generate free cash flow; five, tax rate to be approximately 14% to 16% in the next 2 to 3 years due to the net operating loss carryforwards to be offset taxable income in part. Our estimated consolidated tax rate is based on our current organization and business structure and tech strategies; six, CapEx for PP&E. Last quarter, we discussed about the special investment we are making in Fab 3 for 2020 and 2021. From 2022, we expect the capital spending to return to the moderate level of 3% of revenue or below; seven, by 2023, we will generate free cash flow in excess of 8% of revenue.
These additional financial pro forma metrics will give you a better understanding of our long-term outlook and value creation. We also would like to further share our capital allocation plan in the near future. Our Board and management are actively evaluating all available options to maximize our shareholders value.
Now that we communicated these key pro forma financial metrics, it seems more prudent that we reschedule our Analyst Day to Q1 2021 due to uncertainties around COVID-19 and related matters. We will then our share capital allocation plan and our growth strategic initiatives. We believe this rescheduling will allow for more comprehensive discussion with investors and analysts. The date will be announced in the near future.
In closing, Q3 represented a pivotal chapter of MagnaChip as we successfully closed the sale of foundry business and Fab 4 that ultimately resulted in MagnaChip becoming a pure-play products company with a very healthy balance sheet for the first time. Across the company, we are making well-planned moves to realign our resources, sharpen our R&D focus on key priority areas and improve our operational efficiency.
More importantly, the upswing in demand, which began since July, is continuing into the fourth quarter. We are encouraged by the robust growth opportunities ahead of us, which creates a stronger foundation for profitable growth. We continue to push the envelope on enhancing our competitive position through continuous technology advancement, addressable market expansion and strategic customer engagements.
Now I will turn the call over to Dr. Woo and come back for the Q&A.
