Description

Electroluminescent sticker improvement

This creation is about an electroluminescent sticker that uses the principle of electroluminescence and has a streamlined structure.

Electroluminescence (EL) is a phenomenon that utilizes electroluminescence. The basic principle is to sandwich a suitable luminescent material between two conductive layers. When current flows, the luminescent material emits visible light. The light-emitting element manufactured by using such a light-emitting mode has advantages such as light weight and thin thickness; therefore, in recent years, a light-emitting element such as electroluminescence (EL) is used for a self-luminous display device of a pixel, so-called The illuminating device is eye-catching. As a light-emitting element for such a self-luminous display device, an organic light-emitting diode (OLED) and an EL element are attracting attention, and have been applied to an EL display or the like. Since these light-emitting elements emit light by themselves, their pixels have better visibility than liquid crystal displays, and thus do not require a backlight.

Nowadays, the manufacturing cost of the electroluminescent device cannot be easily reduced, and the substrate to which the electroluminescent device is applied is a hard material, so the field of application is limited.

Although this type of transfer sticker can be externally powered to continuously emit light, its structure is There are multiple layers on the surface, which not only increases the overall structural complexity, but also requires multiple alignment and assembly to increase the cost required during production. Further, the stability of the transfer sticker is also affected. It can be seen that the existing transfer stickers still have room for improvement and improvement in design.
