Is there any difference between a LED display and a LED backlight? Now what's the LED TV set?
We know that the LCD material itself does not emit light, and the light source on the back of the LCD panel provides light support. This source of light has always been based on the CCFL cold light tube, and the luminescence principle of the CCFL cold light tube is similar to that of our everyday fluorescent tube. However, CCFL light emitting diode is also faced with uneven brightness, power consumption is relatively high, and contains mercury and other issues. In contrast, LED backlight in power and material environment to do better, brightness uniformity is relatively high, and the volume can be made thinner. Therefore, LED backlight prospects are very promising vendors. Let's review the basic principles of lcd.In simple terms, LED backlight is the traditional CCFL backlight for LED (light emitting diode, usually white light). It is divided into two types: dot formation (also called straight down type) and side light type. The dot matrix due to uniform brightness, high contrast, natural color, high resolution, long service life, is mainly used for various brands of high-end models; while the side light type is not uniform brightness (do not look carefully, may not see out), but the cost is relatively low, mainly used for various brands in the low-end models.Backlight module from CCFL to LED can bring many benefits, can make the screen brightness more uniform, product power consumption is lower, the shape can be more light and fashionable. However, the W-LED (white light LED) backlight is widely used in the market. In fact, this backlight is only the replacement of the light-emitting components, but the display effect is very weak, not even improved. The obvious improvement of the display effect of the LCD products, RGB-LED (tricolor LED), is more obvious for the display effect, but the production cost is higher, so it is applied to the high price LCD tv.
LED backlight refers to the backlight is composed of LED light-emitting tube, the number of pixels unrelated to it, pixel or LCD screen to achieveLED TV refers to the second
Each pixel of the LED display has a set of LED light-emitting tubes,
