The most prominent advantages of preferred LED TVs are clearer pictures, wider color gamut coverage, and higher color reproduction. This is one of the main reasons why LED TVs are more expensive than ordinary LCD TVs. In addition, LED TVs only use LED as backlight source, and can't necessarily make the picture quality better. It must be backed by good image processing circuit and technology, otherwise there will be no improvement in image quality. Consumers can let the purchaser connect the same signal source when purchasing, preferably the high-definition signal source contrast watch, if the clarity is similar, even better than ordinary LCD TV, it proves that the LED TV has Its name. In addition, the consumer can let the shopping guide adjust the TV screen to the state of no signal or blue screen. If the brightness of the four corners of the TV and the central part are not uniform, or there is light leakage around the screen, this means that the LED TV technology of the manufacturer is very Mature, the most basic image quality circuit processing technology is not done well, and its LED TV quality can be imagined. Second, look at energy saving. LED TV power consumption should be lower than ordinary LCD TV. If the power consumption of LED is not comparable to ordinary LCD TV, consumers should not buy it easily. Again, look at the technology and configuration. One of the most important core technologies of LED TVs is the ability to have backlight zone control. This technology can ensure that the TV has better image quality, lower power consumption and longer service life. In addition, the TV picture clarity and processing speed are critical to the chip. In selecting the LED, it depends on whether there is a 1+1 chipset and a DOT restore system. If the chip processing speed is slow or a single-line chip, the picture will be played during playback. Not smooth, can not achieve point-to-point HD playback, and can not reach the full HD playback standard in the future. The identification method is as follows: under different signal sources, adjusting one of the brightness contrasts in the menu, it will be found that two different signal source parameters are different. If they are the same, the TV is processed by a single chip. In addition, from the perspective of high-definition audio and video playback, LED can play high-definition video VC1, H264, high-definition audio DTS, LPCM and other high-definition formats, which is one of the important criteria for identifying the advantages and disadvantages of LED LCD TV. Then, look at the brand again. LED LCD TVs have only been developed since 2007, and only a few brands in the world really master the LED core technology. Most manufacturers' so-called LED TVs are mostly foundry or grass component production lines. The technology is seriously immature, and there are many technical defects unknown to consumers. Experts warn consumers that the choice of LED TV must focus on the key aspects of image quality, sound quality, etc., not to be attracted by the additional product features or gifts of the manufacturer, because we buy TV, not functions other than TV products. And gifts. Ei 96 Transformer,96 Va Transformer,Ac Current Transformer,Ei Transformer Guang Er Zhong(Zhaoqing)Electronics Co., Ltd , http://www.poweradapter.com.cn
The so-called LED TV strict name is "LED backlight LCD TV", which refers to LCD TV with LED as backlight. It replaces traditional fluorescent tubes with LED light sources. LED TV has better picture quality, longer theoretical life, more energy saving, more environmentally friendly production process, and can make liquid crystal display panel thinner and other outstanding advantages, but not all LED TVs have the above advantages, consumers must purchase æ—¶big eyes.
