Hello, everyone. Lin Fei has come to answer the above questions. What is the difference between ledlcd and ledlcd? many people don't know yet. Now let's take a look!

1. TV is a necessary equipment for people to watch wonderful programs at home. It has a long history and has undergone a series of technological changes. So far, there are two main forms of mainstream TV on the market: lcd and led. Presumably some owners will often hear the introduction of these two forms when buying. Although I have heard a lot, the specific difference is not very clear. The following editor will bring you the difference between TV lcd and led to popularize small knowledge.

2. First, the difference between display and security

3. When introducing the difference between the two, start with the new screen and security. As a backlight source, led can make the display thinner and lighter, and the color rendering effect will be better. Lcd uses cold cathode fluorescent lamps, which are also considered harmful to the environment because they contain mercury. LED LCD TVs use light-emitting diodes, so there is no mercury problem. However, for end consumers, even if the traditional LCD TV containing mercury is used, it will not directly harm the body and the environment in the actual use process.

4. 2. The difference of backlight effect picture.

5. The difference between the two lies not only in the display and security, but also in the backlight effect. In today's well-known liquid crystal technology, it does not glow, so it needs backlight. This lighting technology is divided into lcd and led. Compared with LCD, led technology is more advanced, so the overall visual effect of led TV is better, of course, the price will be higher.

6. 3. The difference between the working principle of led and LCD TV

7. The working principle is the foundation that determines the final effect of electrical appliances, which is also the reason why many electrical appliances should pay attention to the working principle in the manufacturing process. Lcd is a liquid crystal display and led is a light emitting diode. At present, in home TV, the promotion of led is to use LED instead of cathode fluorescent lamp as the backlight of LCD panel. Because the boost circuit is eliminated, it saves electricity, but in fact this kind of TV still uses an LCD screen. Lcd can be used as a real unit. Organic light-emitting diode (OLED) mobile phone displays have been available for some years, but there is still a gap in the practical application of this technology.

8. This is the difference between TV LCD and led. I hope I can help you!

At the end of this article, I hope it will be helpful to you.
