Led display working principle

A: Liquid crystal, a liquid crystal, is a very special substance. It is both liquid-like and has some optical properties of crystals. Liquid crystal was discovered in 1888 by the Austrian botanist Reinitzer, is a kind of organic compound between solid and liquid, with a regular molecular arrangement, the arrangement of liquid crystal molecules has a certain order, and this order is very sensitive to external conditions, such as temperature, electromagnetic field changes. Under the action of the electric field, the arrangement of liquid crystal molecules will change, thus affecting its optical properties, this phenomenon is called electro-optical effect. 

Usually in the two glass substrate is equipped with a mating film, the liquid crystal will be along the groove direction, because the glass substrate mating groove deviation from 900, the molecules in the liquid crystal in the same plane like a shutter one by one neatly arranged, and the direction of the molecules from one liquid level to another will gradually twist 900, that is to say, the phase difference between the arrangement of the two layers of molecules is 900. Generally the most commonly used liquid crystal type is a nematic liquid crystal, the molecular shape is an elongated rod shape, the length and width of about 1-10nm (1nm = 10Am), under the action of different current electric fields, the liquid crystal molecules will do regular rotation of 90 degrees arrangement, resulting in the difference in transmittance, so that the power supply on and off under the action of the light and shade difference, in this principle to control each pixel, you can constitute the desired image. 

LED display classification is diverse, generally in accordance with the following ways to classify

A: (1) According to the use environment, it is divided into indoor, outdoor and semi-outdoor

(2) According to the color, it is divided into monochrome, dual primary color, and three primary colors (full color).

(3) Synchronous and asynchronous according to the mode of control or use

(4) Divided by pixel density or pixel diameter

(5) According to the display performance, it can be divided into full color display, single primary color display, dual primary color display, digital tube or single primary color display;

(6) According to the display device, it can be divided into LED digital display, LED dot matrix graphic display, LED video display
