What is the difference between LCD backlight and LED backlight

It may be that the business vigorously promotes, and we all think that LED is good.

In fact, the difference between them is not very big, please be patient and read it.

The difference between LED and LCD is only in the backlight, the panels are the same.

The merchant said this, which is somewhat deceptive.

Real LEDs are the ones we see on the big billboards on the walls.

Both of their panels are LCD, also called TN panels.

Compare it with the diode is of course good, energy-saving, environmentally friendly, small place, high brightness, and fashionable.

But it's a bit more expensive.

If you are optimistic about these two **, you still buy LED, if the difference is too much, you need LCD.

LCD is also beneficial, I think the lamp is softer, and the adjustable range is relatively high.

Understand, it's pure hand, and I don't want to copy.

Good luck.

It is a display screen that controls the display of semiconductor light-emitting diodes and is used to display various information such as text, graphics, images, animations, video signals, etc. The LED display is divided into **display and **display, both of which are composed of LED matrix blocks. **The display screen can display Chinese characters, English text and graphics synchronously with the computer; **The display screen is controlled by a microcomputer, and the images are rich in real-time, synchronous and clear information dissemination mode** various information, and can also display two-dimensional and three-dimensional animations, videos, TV, VCD programs and live events.

LED display screen display screen bright color, three-dimensional sense of strong, static like oil painting, moving like a movie, widely used in stations, docks, airports, shopping malls, hospitals, hotels, banks, markets, construction markets, auction houses, industrial enterprise management and other public places.

Backlight: In recent years, the backlight has developed rapidly, and new technologies and new products have been introduced, and the LED backlight has gradually entered the industrialization, with a certain scale, compared with CCFL, LED has obvious energy-saving advantages. The kanji for backlight is interpreted as "direct exposure to light" or "direct exposure to light".

In the electronics industry, backlight is a form of illumination that is often used on LCD displays. The difference between a backlit type and a frontlit type is that the backlight shines from the side or from behind, while the front light shines from the front, as the name suggests.

LCD itself does not produce light. It relies on a backlight to illuminate its pixels, especially in environments with high ambient light.

Most LCDs today are backlit with edge lighting. Several white LEDs are mounted behind one edge of the LCD screen, feeding light into a complex setup of light guides, reflectors, and diffusers. LED backlights are typically driven by a pulse-width modulated signal to control screen brightness.

The active matrix mini LED backlight, invented by LCD TV manufacturers, is now moving down to consumer and industrial LCD applications. In the structure of the Mini LED backlight display, the Mini LED is used as the backlight source, arranged in an array to form different local dimming areas, so that the LCD display above can achieve full brightness or full darkness to achieve high brightness and high contrast.

The application of Mini LED as the backlight of LCD display has the advantages of high contrast, power saving, thinness, etc., which can compete with OLED and show obvious performance in LCD display applications.

LED backlight is an LCD TV that uses LED as a backlight module. LCD TV with LED backlight technology - the backlight is replaced with LED, and the panel is still LCD! Replacing an LED backlight can save energy, making the panel thinner and more beautiful in appearance

LCD backlight refers to the liquid crystal display uses the old tube backlight circuit, the new one is the LED backlight circuit, the new circuit has the characteristics of low energy consumption and high brightness.

LCD is the liquid crystal display of mobile phones.

LCD, is the abbreviation of Liquid Crystal Display, the structure of LCD is to place liquid crystals in two parallel pieces of glass, allowing many vertical and horizontal tiny wires between the two pieces of glass, through the power or not to control the rod-shaped crystal molecules to change direction, the light is refracted to produce a picture. Selecting the appropriate test module in the test can play a good connection function, and can play an excellent role in the on-current and transmission signal. The high-current shrapnel microneedle module is a test connection module suitable for LCD screen testing.

LED backlight refers to the use of LED (light-emitting diode) as the backlight of the liquid crystal display, and the LED backlight display is only the backlight of the liquid crystal display, which transitions from the traditional CCFL cold light tube (similar to fluorescent lamp) to the LED (light-emitting diode). The imaging principle of liquid crystal can be simply understood as that the external application of voltage to deflect liquid crystal molecules will block the transparency of the light emitted by the backlight like a gate, and then project the light in different colors of color filters to form an image.

LED display is a set of microelectronic technology, computer technology, information processing in one, with its bright color, wide dynamic range, high brightness, long life, stable and reliable work and other advantages, become the most advantageous public display, LED display has been widely used in large squares, commercial advertising, stadiums, information dissemination, news releases, transactions, etc., can meet the needs of different environments. LED display is a display method that controls semiconductor light-emitting diodes, which is generally composed of many light-emitting diodes, usually red, and displays characters by turning the lights on and off. A display screen used to display various information such as text, graphics, images, animations, video signals, etc.

OLED display is considered to be the emerging application technology of the next generation of flat panel display due to its excellent characteristics such as self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panels, wide temperature range, and simple structure and manufacturing process.

Many netizens are easy to associate OLED with LED backlight, which is hyped by manufacturers, in fact, OLED and LED backlight are completely different display technologies. OLED emits light by driving the organic film itself with an electric current, and the light emitted can be red, green, blue, white and other monochrome, and it can also achieve a full-color effect. Therefore, OLED is a new luminous principle that is different from CRT, LED and liquid crystal technology.

In general, LED display, LED backlight, OLED are three completely different imaging technologies.
