Seiko EPSON developed a white organic EL headlamp source

Seiko EPSON has developed a white organic EL element as a light source, and in the SID 2008 release. The method of the invention is that a white organic element is formed on the bottom of the glass plate by the interval of 150 m, and is sealed by a glass substrate. Luminescence of white organic EL elements on glass substrates. Compared with the prior light source of LED and CCFL, such as the etching part of the glass bottom plate, the utility model has the advantages of low viewing angle dependence, and easy realization of thin section, without the need of light guide plate and other components.

The shape of the new product is 30mm * 30MM, thickness of 0.8mm. "The previous way of the headlight thickness is about 1mm" (Seiko EPSON), the new product is thinner. By grinding the glass base plate, "still looking to 0.4mm" (Seiko EPSON).

The construction of the white organic EL element is the same as that of the common organic EL panel, and can also achieve a certain degree of scale (Seiko EPSON). The development of products can be equipped with reflective LCD panel, electronic paper, automotive and MEMS display products.
