EL experts have developed a complete thixotropic PTF ink system that uses the ink to print all the coating materials that make up EL lamps on a variety of substrates. The reason why we should concentrate on the term thixotropic is that when developing a new ink system, we must try to avoid the two disadvantages of the current technology: one is that the EL film is completely packed; the second is the pre- Indium tin oxide (ITO) coated polyester film.

The thixotropic ink is used as a primer, and all the coating materials of the EL sheet are separately mixed with it. All the powder and pigment particles are kept in suspension in the thixotropic ink primer (even the most insoluble components, such as capsules. The phosphor luminescent material and the pre-sprayed ITO also did not produce precipitation.

In cooperation with the best ITO powder manufacturers, a new ITO ink with a resistivity of 1000 ohms/mil2 and excellent light guiding properties has been developed.

Since the entire structure of the EL sheet uses the same thixotropic ink resin as a primer, it becomes a layered monolithic structure with good adhesion between layers and adhesion to various substrates. well.

The versatility of PTF ink means that it can be printed on the front side of the glossy side or printed on the reverse side. The printing area can be small or large - the traces are connected by the printed silver material. The terminal is consistent with the leads used in other thin film circuits. .
