Classification of electroluminescent powder

 

Inorganic powder electroluminescent (EL) material is a kind of inorganic powder luminescent material that converts electric energy directly into light energy. Its luminescent color mainly includes blue, green, orange, and the transition color of the above colors. KPT brand EL materials can be widely used in EL glass screen, EL enamel screen, EL plastic screen, EL wire and other AC and DC electroluminescent devices. At present, the screen making process of EL devices is mainly screen printing or spraying, so the EL phosphors produced by our company are divided into three types:

Class B: average grain size 29 m. Features: high brightness, high temperature resistance, suitable for plastic screen and enamel screen;

Class S: average grain size 9 m. It is characterized by high brightness, uniform and delicate light, suitable for glass and plastic screens;

Class C/CT: average grain size 28/25 m. The characteristics are that the particle surface is coated, with good moisture-proof performance, long service life, high brightness, no need for packaging, suitable for plastic screen;

 

Class DC: the average particle size is 10 microns, characterized by DC orange electroluminescence, suitable for glass screen.

2? Special materials for EL production

It is mainly used for screen printing and making EL luminescent film.

 

There are five common models of EL luminescent materials (large particles, small particles, blue-green, white, etc.)

One type of EL dielectric material is commonly used (white, 3-5 micron particles, high dielectric constant)

Two types of EL highlight glue are commonly used (PB type and AB type)

ITO film is commonly used in 3 models (thickness 0.175mm 0.025mm)

EL conductive silver paste is commonly used in 1 model (for conductive layer and back electrode)

There are three common models of EL control driver (DC3V, DC12V, AC220V, etc.)

There are 5 kinds of EL production equipment commonly used (screen printing, drying, UV machine, etc.)

3? Auxiliary raw materials and use consultation

The special auxiliary materials for the manufacture of electroluminescent devices developed by Keyan Optoelectronics can be used in combination with all kinds of EL luminescent materials. It is fully applicable to the implementation of the screen printing and spraying process of EL glass screen, enamel screen, plastic screen, silk thread and other device products. And can provide EL device production process consulting services

The index reference of various EL devices manufactured with this auxiliary material is: voltage 40V ~ 400V, frequency 50Hz ~ 4KHz, temperature - 40 ~+60 ?, current 0.02 ~ 0.2mA/cm2, capacitance 0.2 ~ 0.7nF/cm2, power consumption 2 ~ 7mW/cm2, humidity 0% ~ 90%, average service life 8000 hours, brightness 70 ~ 100cd/m2.

 

Model and application characteristics

High brightness AB component adhesive printing luminescent layer The dielectric layer is mixed with the dielectric powder, mixed with the luminescent powder, with strong adhesion, and dried at 110 C for 1 hour

High reflectivity and high dielectric constant of dielectric layer printed by dielectric powder

The modifier is added to the A and B component pastes for plasticizing and curing

Diluent, cleaning agent, viscosity adjustment, dilution of cleaning tools, cleaning

ITO film plastic transparent conductive film transparent and soft

Conductive silver paste printing back electrode has good conductivity

The back electrode protected by insulating coating is simple to use
