What is the difference between led and What are the advantages and disadvantages of led and ? So what is ? is also a kind of backlight, but compared with led, is not bright enough. LCDs are generally used as backlights for electrical appliances. For example, most of our mobile phones and TVs use LCD backlights, because LCD backlights are less harmful to the eyes. So do you know the difference between led and ? The difference between led and : 1. LCD is the full name of mobile LCD screen display, mainly including TFT, UFB, TFD, STN and other types of liquid crystal displays. 2. LED is the English abbreviation of Light Emitting Diode. LED applications can be divided into two categories: one is LED display screens; the other is LED single-tube applications, including backlight LEDs, infrared LEDs, etc. Now as far as LED display is concerned, China's design and production technology level is basically in sync with the international level. The LED display screen is a display composed of light-emitting diodes arranged in one piece. It adopts low-voltage scanning drive, and has the characteristics of less power consumption, long service life, low cost, high brightness, less failure, large viewing angle, and long viewing distance. 3. Compared with LCD displays, LED displays have more advantages in terms of brightness, power consumption, viewing angle and refresh rate. Using LED technology, it is possible to create displays that are thinner, brighter and clearer than LCDs. The power consumption ratio of LED and LCD is about 1:10, and LED is more energy-efficient. 4. LED has a higher refresh rate and better performance in video. LED provides a wide viewing angle of 160°, can display various text, numbers, color images and animation information, and can play color video signals such as TV, video, VCD, DVD, etc. 5. The reaction speed of a single element of the LED display is 1000 times that of the LCD mobile LCD screen screen. It can also be looked after under strong light, and it can adapt to the low temperature of minus 40 degrees. Simply put, LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystals, while LED is a display screen composed of light-emitting diodes. 6. The LED display currently on the market is not a real LED display. To be precise, it is an LED backlight LCD screen. The LCD panel is still a traditional LCD screen. In a sense, how much is this? Contains fraudulent qualities!. For mobile LCD screen displays, the most important key is its liquid crystal panel and backlight type, and the LCD panel of the display on the market generally adopts TFT panel, which is the same. The difference between LED and LCD is only their backlight type: LED The backlight and CCFL backlight (that is, fluorescent lamps) are diodes and cold cathode lamps, respectively. The above is the introduction of the difference between led and . Led is a kind of high-brightness backlight. Now most of the smart TVs and smartphones are backlighted with leds, and many lamps also use leds. Leds are relatively popular in the current market because they are more practical. However, the backlight of will cause less damage to the eyes. It is generally used in digital products and is a backlight with long life and low cost. The essential difference between Led and mobile phone LCD is that the brightness of the two is different.
