This LED vs.The comparison of LCD HD TVs intends to present some facts about these highDefine TV, which will help you eliminate some prominent myths about them.If you are thinking of buying either of these two products, this must be read.To put it bluntly, there was nothing called "led hd TV" at first;What we call led TV is basically LCD TV with LED backlight instead of traditional CCFL backlight.This improper use of words can be attributed to the active marketing of manufacturers and retailers who have introduced LEDAt the beginning of the 21 st century, backlight LCD TV as led TV.Confused?It's not as hard as it looks.When you finish half of the article --All your misconceptions will be cleared.High-High-definition TV is referred to as high-definition TV, which is a TV set that is easy to transmit high-definition TV.Thanks to the amazing resolution of the 1920x1080 or 1280x720 pixels they brag about, HD video.These TVs are slowly but steadily phasing out their predecessors.e., the standard-TV (.k.a.SDTVs).Nowadays, almost all TV models on the market adopt high-definition TV technology;LCD TV is no exception.In short, LCD TV is also called Liquid TV.LCD TV is a TV that uses LCD technology to make and display images.In this technique, the images displayed on the screen are generated by selectively filtering the white light generated by the light source used in it.When the LCD TV was launched in the 20 th century, they used a series of coldA cathode fluorescent lamp (CCFLs) placed as a light source behind the display ).Recently, however, these CCFLs are light-LEDs (LEDs), they are either arranged in the array behind the display (back-lit or full-Array led TV) or along the edge of the display (edge-Led TV ).It is the use of LED bcklighting that makes the new LCD TV model get the popular name led TV.However, the fact remains that the led TV sold today is nothing more than an LCD TV with LED backlight and should be called an LED-LCD TV backlight.On the other hand, those LCD TVs that use the CCFL backlight as a light source should be called CCFL-LCD TV backlight.If this difference between LCD and LED technology is taken into account, we should compare LED-Backlit LCD TV with CCFLIn contrast, the backlight LCD TV.Just because both use LCD technology does not mean that they pass through and pass through the same.There are indeed quite a few differences between the two, and you need to consider them when deciding between them.As you must have realized now, LED-LCD and CCFL backlight-Backlight LCD displays are the backlight sources they use.The former relies on weak light.LEDs are used as light sources, which use cold-Same cathode fluorescent lamp.LED is relatively new on the blockBacklight LCD TVs do have some advantages over CCFLbacklit TVs.Start with power consumption, select LED-Backlight LCD TV is a better option because these units can save 40% of power compared to CCFLbacklit units.RGB color wheel used in LEDBacklight TVs add bright colors and give them an advantage in terms of image quality.At this time node, it is difficult to determine which of these two has a longer life span, but given the light-The lifetime of the LEDs is longer than the fluorescent lamp (because the fluorescent lamp will fade over time), which is undoubtedly the advantage of the led TV.Again, you may experience the halo effect when it comes to full --array LED-Backlight TV does have a tendency to sweep.The price is another aspect of the LCD TV relative to the led TV, perhaps the most critical aspect, which becomes more obvious when you compare the price of the same size device.While most led hd TV reviews suggest that the contrast of these devices is better and the black is deeper, LCD TVs are catching up quickly in this regard.Being high-Define TV, when it comes to speed, you can hardly see any difference between the twomoving videos.In terms of environmental friendliness, CCFLs used in LCD displays contain mercury, which makes these TVs potentially harmful to the environment.As the fighting between the two continues to heat up, differences between them are expected to narrow.At the end of the day, everything depends on your personal preferences.If you prefer to spend extra money instead of compromising on quality, you can choose led TV.However, if the price is the driver you care about, then LCD is your best choice.
