What is the difference between the LED backlight screen and the LED screen? (detailed description)
The LED display can display the changing numbers, characters and graphics. It can be used not only in the indoor environment, but also in the outdoor environment. It has the incomparable advantages of projectors, TV wall and LCD screen.
And LED backlight means that the backlight is LED, rather than silver light, more power saving, in fact, the LCD panel is also LCD.
LED has been widely valued and developed rapidly. It is inseparable from its advantages. These advantages are: high brightness, low working voltage, low power consumption, miniaturization, long life, shock resistance and stable performance. LED has a bright future, and is developing towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability and panchromatic.
LED display is divided into graphic display and video display, all composed of LED matrix blocks. Graphic display can be displayed Chinese characters, English text and graphics and computer synchronization; video screen using microcomputer control, graphic, image, play all kinds of information in real-time, synchronization, clear information dissemination way, but also shows 2D, 3D animation, video, TV VCD programs and live. The LED display screen display bright colors, stereo sense is strong, such as oil, such as films, widely used in finance, taxation, industry and commerce, telecommunications, sports, advertising, industrial enterprises, transportation, education system, station, wharf, airport, shopping malls, hospitals, hotels, banks, securities market, the construction market, auction management, industrial enterprises and other public places.
The 1.led is an active light source that lights up when energized. The LED screen is the LED array. On specific functions, it is used as a large display. For example, 2M x 1.5M outdoor large display, such as shopping malls advertising screen.2.led backlight, since LED is an active light source, can be used as a light source. The more commonly used is the LCD display, where we have to say LCD, LCD is the abbreviation of liquid crystal display. The operating principle is that the LCD produces deflection at the desired operating voltage. Shading effect. Then there is a beam of light at the back of the LCD to see the display of the liquid crystal. So, LCD must have a backlight. This can be done very well with a high brightness white light diode. The early LCD's Backlight was a fluorescent light (which can be interpreted as a small daylight lamp). Say here, you see?.Summary: LED is a light source, the specific application of different, the role is also different. LED screen is dynamic work. As a light source, it works steadily and steadily. Now we have the LED backlight projector. Hope to be of help to you
