Accumulated in March, monthly revenue increased by 60%, Q2 revenue will continue to increase

The LED driver IC factory accumulated revenue of 198 million yuan (NTD, the same below) in March, with a monthly increase of 59.31% and an annual increase of 21.03%; Q1 revenue of 457 million yuan, a quarterly decrease of 12% and an annual increase of 10.02%.

Looking forward to the market outlook, the accumulation pointed out that with the arrival of the traditional peak season, coupled with the continued introduction of new products in the LED display driver IC and the gradual recapture of the market share, Q2 revenue will continue to increase, and the estimated monthly revenue for April-June is expected. It is expected to maintain a scale of 200 million yuan similar to that of March.

The current product portfolio is still dominated by LED driver ICs for display screens, accounting for more than 90% of the total revenue. As for LED lighting (including LED lighting wall washers, panel lights, etc., and LED architectural lighting), etc. The proportion of income is still less than 10%. If it is divided by the proportion of revenue in each region, mainland China accounts for about 2/3, while European and American markets account for 1% to 20%, and the rest are Taiwan and other parts of Asia.

Regarding the operation trend this year, the accumulation shows that after the reorganization and elimination of the LED display industry in mainland China in recent years, supply and demand have gradually become healthy, and the accumulation of their own products has gradually been put in place, including the introduction of the cost of the general-type LED driver IC. The -down version, while also launching new products on the ultra-dense screen, accumulates the overall operation this year.

USB3.0 is a USB specification, which was initiated by Intel and other companies. The maximum transmission bandwidth of USB3.0 is as high as 5.0gbps (500MB / s).
While maintaining compatibility with USB2.0, USB3.0 also provides enhancements: significantly increased bandwidth (up to 5Gbps full duplex); better power management; 
more power; faster device identification; and higher data processing efficiency.  
The reason why USB 3.0 has the performance of "speeding" is entirely due to the improvement of technology.
Compared with USB 2.0 interface, USB 3.0 adds more physical buses in parallel mode.
You can pick up a USB Cable and look at the interface.
On the basis of the original 4-wire structure (power supply, ground wire, 2 pieces of data), USB 3.0 adds 4 lines for receiving and transmitting signals.
So there are eight lines in the cable and on the interface.
It is the additional 4 (2 pairs) of lines that provide the bandwidth required for "superspeed USB" to achieve "over speed".
Obviously, two (1 pair) lines on USB 2.0 are not enough.
In addition, in the signal transmission method, the host control mode is still used, but the asynchronous transmission is changed.

USB 3.0 makes use of two-way data transmission mode instead of half duplex mode in USB 2.0 era. In short, data only needs to flow in one direction, which simplifies the time consumption caused by waiting.

In fact, USB 3.0 does not take any rarely heard of advanced technology, but theoretically increases the bandwidth by 10 times. As a result, it is more friendly and friendly. Once superspeed USB products come out, more people can easily accept and make better customized products.
