Many people have more or less concerns before buying TV: What brand to buy? What size to buy? OLED TV, Quantum TV, LCD TV, which TV is best for you? I believe many people Have considered such a problem.

From the current market structure, OLED TVs are indeed the general trend, but higher prices lead to high thresholds; quantum dot TVs can be described as “sub-era versions” of LCD TVs. Although the picture quality is improved, there is no essential difference. Although LCD TVs are relatively traditional technologies, LCD TVs are still very strong, and LCD TVs are still in the mainstream of the market.


Therefore, for most families, an LCD TV with excellent picture quality and reliable quality is worth having. In the field of LCD TVs, Hisense and Sharp have the greatest influence. In particular, Hisense's original ULED technology and Sharp Huangcai technology are popular with people. The corresponding new products are Hisense EC880 and Sharp LCD-60SU. Which of these two televisions is more worthwhile? It is still necessary to start with a technical perspective.


Hisense ULED technology's biggest feature is that it can create a strong high-contrast effect, the backlight can achieve independent control of the partition, according to the brightness and darkness of each frame to automatically adjust the brightness of the bright part of the screen, the darker the darker, more high contrast Facilitate the eyeballs, especially in the backlight, metering and other large light than the scene more clear and more three-dimensional. At the same time, full-channel resolution enhancement technology and MEMC stereo anti-shake technology also enhance the sharpness of the picture, and the visual experience is even better. Huang Cai technology is Sharp's housekeeping technology, and advanced backlight technology can also improve the clarity. However, as far as technological development is concerned, Hisense ULED technology is obviously more recent than Huangcai technology, merging high contrast, high definition, high color gamut, and high fluency to bring about a better visual experience. In contrast, Sharp Huang Cai technology has some meaning to eat, especially after being acquired by Foxconn, Sharp's high-end positioning before changing to cost-effective play, which also makes Sharp's brand value has been discounted.

Therefore, from the technical point of view or from the brand point of view, Hisense TV is more worthy of possession, EC880 equipped with ULED technology to bring a better visual experience, curved screen is also more to please the eyes, for most families are very suitable.

The role of the car amplifier is to select and preprocess the audio input signal, and to amplify the power, so that the electrical signal has the ability to drive the speaker. Car power amplifiers are slightly different from those in ordinary home theaters. Because many car hosts integrate power amplification functions to play a pre-amplification function, car power amplifiers are sometimes called post-amplification, which means that they can be connected and amplified. High level input over.
Amplifier is an indispensable component of a good sound system. The power amplifier on the host often cannot really amplify the sound current, so if you want to have a good music experience, you must install a power amplifier. Generally speaking, the power of the power amplifier is greater than the power of the speaker. Many car owners think that installing a bass amplifier is just to have a shocking effect. In fact, this is ignoring the characteristics of the car. No matter how high-end cars are, there will be noise. The bass part of the music released during driving will be different to different degrees. The roar is mixed, and the addition of a bass amplifier can increase the reserve power, reduce noise interference and reduce distortion.
When the power tube of the power amplifier is working, the temperature of the tube core is about 120 degrees, and the heat must be dissipated in a certain way. But the temperature of the Heat Sink exceeds 60 degrees, and even the case is hot, which may be a problem. Therefore, it can be seen that adding a cooling fan with good cooling performance and high reliability is a necessary way and the key to solving the heat dissipation problem of the power amplifier system.
