What is the expected increase in revenue for the small and medium-sized display IC business in the second quarter compared to the previous quarter 
anying the rapid growth of 5G and high-performance computing, there's a noticeable increase in demand for semiconductor for advanced processes. The trend toward an ever more connected digital world also drives higher needs for mature nodes, notably demands from display driver IC, power management IC, CMOS image sensor, automotive industry and various AIoT devices that are already all around us and still increasing rapidly in number.
Adding these all up, what we have is a structural shift in demand and supply dynamics, especially for the mature nodes, which have lacked meaningful capacity expansion for many years. As I mentioned on our last earnings call, we have managed to secure more capacity for this year compared to last year, with accessible capacity expected to grow quarter-by-quarter during 2021. Looking further ahead, we are taking measures to work with our strategic foundry partners to further enlarge our long-term capacity pool. We'll give more details as they come about.
Separately, taking advantage of the current favorable environment, we are also making efforts to reposition ourselves toward higher-end and high value-added products by working more directly and closely with select leading end customers. We have made tremendous progress across various industries that we serve. For large display areas, we are pleased with the results so far in switching our focus more toward high-resolution TV, high-performance monitor and low-power notebook.
For smartphone, wearable and tablet, we are gearing up for the AMOLED driver IC development in partnership with strategic customers and foundry providers. For automotive market where we are already the leader in display driver IC, we are deepening our working relationships with Tier one players and end customers across all major markets. Last but not least, in our nondriver areas, we are pushing hard for the promotion of WiseEye ultra-low power AI sensing solution, which have been -- which have seen widespread adoption for numerous AIoT applications.
Our 3D decoder IC is also already ramping in volume. I will elaborate on this in a few minutes. Now let us start with an update on the large panel driver IC business. For the second quarter, we expect large display driver IC revenue to increase by around 20% sequentially, with the three major product lines offset for further growth. We expect decent increase in both monitor and notebook IC sales in Q2, thanks to persisting work-from-home and learn-from-home demands. For the TV IC segment, we anticipate an impressive quarterly growth in Q2, mainly due to shipments of high-end TV products going to a world-leading end customer, an illustration of the strategy toward high-end products and leading end customers that I just mentioned.
Nevertheless, our shipping quantity is constrained by capacity shortage for the large panel display driver IC business during the second quarter. Recently, we saw strong customer demand for high-end monitors unfolding post pandemic. When people work, study and play games at home, which they do much more than before, they are demanding high resolution, higher frame rate, ultrawide aspect, curved view an even multiple monitors sometimes. Himax continues to lead the high-end monitor market by providing advanced driver ICs and Tcons in partnership with leading panel makers and end customers.
Now let's turn to the small and medium-sized display IC business. In the second quarter, we see continuous strong demand for all three segments, namely smartphone, tablet and automotive. Again, we are unable to meet all customer demands due to tight foundry capacity. As the leading supplier for the Android tablet market, we are strategically allocating capacity in favor of tablet over smartphone to support the needs for home working and remote learning. For the second quarter, we expect tablet sales to grow by mid-teens and smartphone sales to be flattish compared to the previous quarter, reflecting our capacity allocation decision.
