In the world of consumer electronics, the "golden September and silver October" period has always been a crucial time for sales. As autumn approaches, many industries gear up for a surge in demand, aiming to capture market share in the second half of the year. In the traditional television industry, Sharp, known as the "father of LCD," has launched a new line of 4K ultra-high-definition large-screen TVs, focusing on consumer needs to deliver an enhanced audiovisual experience and bring high-quality, large-screen TVs into everyday life.
The new lineup includes models such as 50SU570A, 60SU570A, 70SU570A, 50SU575A, and 70SU575A, available in 50-inch, 60-inch, and 70-inch sizes. As the saying goes, “watching TV starts with the screen,†and these Sharp TVs are no exception. They come equipped with 4K ultra-high-definition displays, and with the growing availability of 4K Blu-ray sources and gaming consoles like Xbox One S, choosing a 4K TV is a smart long-term investment.
For users who demand more from their screens, the 60-inch and 70-inch versions offer even better performance. These models feature original Sharp panels with higher light transmittance and wide color gamut technology, delivering vibrant colors, accurate saturation, and natural brightness without harmful elements like heavy metals or indium. This makes them not only visually superior but also healthier and more eco-friendly.
Beyond the display, the audio quality of these TVs is equally impressive. All six models support Dolby Audio and DTS decoding, ensuring a balanced bass and detailed mid-to-high frequency sound. The sound range covers from 100Hz to 20kHz, creating a rich and immersive audio experience. Even subtle sounds like footsteps or breathing are clearly audible, bringing movie-like realism into your home.
The user experience is further enhanced by the Taitum operating system based on Android 4.4. It features a personalized interface, fast remote control functions, and one-touch access to favorite content. To ensure smooth performance, the TVs are powered by a 64-bit dual-core CPU and quad-core GPU. The 50SU570A, 60SU570A, and 70SU570A models come with 1GB RAM + 8GB storage, while the 50SU575A, 60SU575A, and 70SU575A models are upgraded to 1GB + 16GB, offering greater flexibility for multimedia use.
Sharp has also partnered with iQiyi, integrating the Galaxy Kiwi service directly into the TVs. This provides access to a vast library of high-definition content, including Chinese cinema, Hollywood films, and various formats like 1080P, 3D, 4K, and Dolby. No more searching for the right movie—everything you need is at your fingertips.
A great TV isn't just about one feature—it's about balance. Like a wooden barrel, it needs all parts to be strong to hold more water. Sharp has improved its manufacturing process, optimized its supply chain, and leveraged core technologies to stand out from low-cost internet brands. With the launch of this new lineup, Sharp is poised for a strong comeback, and its future market performance looks very promising.
Currently, the 50SU575A, 60SU575A, and 70SU575A models are available for reservation on JD.com. Buyers can enjoy free accessories like bonus racks, HD cables, and even items like WMF pots and Bluetooth game controllers for certain models.

High Frequency Power Supply
I. Definition and overview
A high-frequency UPS is an Uninterruptible Power Supply (UPS) technology. It uses the high-frequency switching power supply technology to convert the input AC power into high-frequency AC power through the inverter and then converts the input AC power into stable direct current (DC) power for electronic devices. High frequency UPS plays an important role in modern power supply system because of its efficient conversion rate, small size design and fast response ability.
Two, the main characteristics
Efficient conversion rate:
High frequency UPS adopts a new IGBT (insulated gate bipolar transistor) inverter technology, and its conversion efficiency can reach more than 90%, which is much higher than the traditional low-frequency UPS, effectively reducing energy loss and improving the use efficiency.

Small volume design:
Because high-frequency UPS uses a more compact design, its volume is significantly smaller than low-frequency UPS, and its footprint is smaller, which is very suitable for use in space-limited environments, such as data centers and computer rooms. (source ibid.)
High power density:
The power density of high-frequency UPS is large, and it can provide greater power output in a small volume, improving the capacity and power supply efficiency of the equipment.
Quick response:
The high frequency UPS has a fast response capability and can provide stable power for the device immediately when the power supply of the grid is interrupted, ensuring that the continuous operation of the device is not affected.
Intelligent management:
Many high-frequency UPS are equipped with advanced intelligent management systems, which can monitor the status of power supply, battery status, load situation in real time, and have fault diagnosis, automatic switching, remote monitoring and other functions, improving the reliability and maintainability of the system.
