Many customers come to warner for LED display, but when the business personnel analyze led and LCD with customers, the customers are confused. They don't know much about LED, but now they come out with an LCD, and the customers are confused. So in this case, Xiaobian here will introduce what led and LCD are and the difference between them.

so in this case.

How to distinguish whether the display is LCD or LED

here's what LED and LCD are and the difference between them.
let's introduce them1、 What is LCD? What is LCD splicing screen?LCD is the full name of liquid crystal display.
there are mainly TFT, ufb, TFD, STN and other types of liquid crystal display, which can not locate the program input point on the dynamic link library.
LCD is the full name of liquid crystal displayLCD splicing screen is a splicing screen which uses LCD display unit splicing.
through splicing control software system, large screen display effect can be realized.
at presentFor more details, please refer to the following materials:LED and LCD are confusedWhat is led? What is LCD? What's the difference between the two?http://www.hnhnled.com/article141.htmHenan Warner electronics large LED display engineering company will answer for you.

LCD is now a common display device.
and LED is usually used in high-end notebook displays.
its display color is softerLCD is the abbreviation of liquid crystal display.
the structure of LCD is to place liquid crystal in two parallel pieces of glass. There are many vertical and horizontal small wires between the two pieces of glass. The direction of rod-shaped crystal molecules can be controlled by power on or not,It's much better than CRT to refract the light to produce a picture.
but the price is higher than CRT.
the price of CRT is higher than CRTLED (light emitting diode) is a kind of solid-state semiconductor device, which can directly convert electricity into light.
the heart of LED is a semiconductor chip.
one end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, The whole wafer is encapsulated by epoxy resin.
the semiconductor wafer is composed of two parts.
one part is p-type semiconductor, in which the holes are dominant, and the other end is n-type semiconductor, There are mainly electrons here.
but when the two semiconductors are connected, a "p-n junction" is formed between them.
when the current acts on the chip through the wire.
electrons will be pushed to the p region, where electrons and holes compound and then emit energy in the form of photons, This is the principle of LED light emission.
and the wavelength of light is also the color of light.
is determined by the material forming the p-n junction.

this is the principle of LED light emission
