LED is light emitting diode
LED is the abbreviation of light emitting diodeLED applications can be divided into two categories: one is led single tube applications.
including backlight LED, infrared LED, etc; At present, there is still a certain gap between China and the world in the manufacturing of LED basic materials, but as far as LED display is concerned, China's design and production technology level is basically in line with the international level.
in addition, there is a gap between China and the world in the manufacturing of LED basic materialsLED display is a display device composed of LED arrays.

What are the advantages of LED backlight screen?

it is driven by low voltage scanning.
it has the following characteristics: low power consumption, long service life, low cost, high brightness, few faults, large viewing angle, long viewing distance, etc.
it has the advantages of low power consumption, long service life, low cost, high brightness, less faults, long viewing distance, etcThe original text of LCD is liquid crystal display.
it is composed of the first letter of each word, which is often called "liquid crystal flat panel display" or "liquid crystal display" in Chinese.
its working principle is to make use of the physical characteristics of liquid crystal: the arrangement becomes orderly when power is on.
it makes light easy to pass through; The advantages of LCD are: compared with CRT display.
the advantages of LCD mainly include zero radiation, low power consumption, small heat dissipation, small volume, accurate image restoration, sharp character display, etc.
choose LCD.
there are several basic indicators: high brightness: the higher the brightness value, the higher the brightness value, The brightness unit is CD / m2.
that is, candlelight per square meter.
the brightness value of low-level LCD is as low as 150 CD / m2, while that of high-level display is as high as 250 CD / m2.
the brightness value of low-level LCD is as low as 150 CD / m2High contrast: the higher the contrast is.
the brighter the color is, the more saturated it will be, and the more three-dimensional it will be.
on the contrary.
if the contrast is low, the color will be poor, and the image will become flat.
the contrast value is quite different.
there are as low as 100:1 and as high as 600:1, Even higher.
wide visual range: simply speaking,
refers to the clear range that can be seen in front of the screen.
the larger the visual range, the easier it will be; The smaller the value is, the clearer the picture will be if the viewer changes the viewing position a little.
the algorithm of visual range is from the middle of the picture.
the clear angle range of the picture is from the top, bottom, left and right directions.
the larger the value is.
the wider the range is naturally, but the range of the four directions is not necessarily symmetrical.
some manufacturers will add the angle values on both sides and mark them as horizontal: 160 °; Vertical: 160 °; It may also be labeled left / right separately: ± eighty °; Up / down: ± eighty °. signal response is very important for animation and mouse movement.
generally speaking, this phenomenon only occurs on LCD, The faster the signal response time is, the more convenient the task processing is.
one of the ways to observe is to move the mouse quickly (that is, the mouse keeps moving down to indicate to the system.
the system keeps responding to the signal to the display),When the cursor moves quickly, it will disappear in the process. It will not appear again until the mouse is positioned and no longer moves for a short period of time; When moving at normal speed, you can also see the trace of mouse movement clearly.
while the response time of ve500's ultrafast signal is as fast as 16ms.
it allows the cursor to move without time difference, and the moving process is clear and easy to see, which does not bring work trouble.
.
first, it provides a super long service life without being inferior to the traditional backlight brightness and contrast, The performance was stableSecond, LED display technology has thinner thickness and lower voltage power consumption compared with traditional technology under the same specification.
this paper introduces the advantages of LED display technologyThird, because of the manufacturing process and raw materials.
LED does not contain mercury, so it is more environmentally friendly.
LEDFourth, the reaction speed is faster.
the reaction speed of single element of LED display screen is 1000 times of that of traditional screen.
the reaction speed of single element of LED display screen is 1000 times of that of traditional screenFifth, it has strong adaptability.
it can be looked after under strong light and adapt to lower temperatureSixth: visually.
it can provide a larger viewing angle, higher brightness, higher color saturation, and cover a wider gamut.
.
.
it can provide a wider range of colors
