Description of the invention [Technical Field (1) Field] The present invention refers to a structure that is mainly a luminous EL element depending on the light [previously, the following is used as a backlight for the backlight collar structure The layer electrode layer 7 5 is used to make the EL and thus to make the original luminous color, etc., but the luminous color is different from the color of the base, which is a kind of noctilucent type electroluminescence combined with noctilucent powder and EL element to absorb external light source, and can Type Electro-Excitation Light (EL)] The electromechanical-excitation light-emitting element (L element) itself is thin and is usually used for production; please refer to Figure 8 for the red pigment mixed with yellow but these general mixed fluorescent Pigment or dye, when the light disappears, the technology is generally called the E element field. The EL element is successively coated with a 7 21, a light emitting layer 7 3, and an insulating encapsulation layer 7. The front electrode layer 72 and the back side The light-emitting layer 73 of the element can generate the EL element in the market application. When the backlight is PDA, mobile phone, etc., the color is generally only green, blue-green, orange, and white. Red, timing, blending photoluminescence fluorescent light, for example white light or a dye-element E L, and hair from yellowish green pigment or dye. Light-emitting (EL) elements, especially manufacturing techniques, make them available at night or in dark places.

Electro Luminescent sheet, shown in market applications as PDA, mobile phone, etc., is a conventional EL element transparent substrate layer 7 1, a positive electrical induction layer 7 4, and a back electrical layer 6, and has a sheet shape. Borrow electrode layer 75-AC voltage, the effect of light. It is mainly used as a backlight element. Due to the limitation of the original materials, the dark blue, orange and white have a shorter service life. Moreover, for this reason, the market today requires its pigments or dyes, and the addition is a blue-green luminescent powder blended powder. EL element is green luminescent powder

Explanation of the invention (2), that is, stop the light-emitting action, and it is impossible to explain why the above-mentioned conventional constitution is used. [Objective and Effect] The environmentally-friendly effects of the noctilucent electric excitation of the present invention, which is coated or applied to its light source and storage source, can be made into the elements of the present invention. [Technical Content] The present invention is not The electromechanical excitation light element is a light-emitting layer composed of particles. The light-emitting layer is superposed with a back electrode layer excited by the majority of the light-emitting particles in the front electrode layer, and the back electrode is installed; Night light layer, which, that into. The detailed descriptions of the above and other embodiments of the present invention and the continuous luminous illumination in the drawings are less practical and lacking, and they have to be improved. The main purpose is to 'energe energy in one layer in the light (EL) element. The function is to solve the above-mentioned problems and provide a piece. Since the luminous layer in the EL element of the present invention has absorption, the EL element has the advantage of saving the luminous backlight which can be mixed with other fluorescent pigments and mixed with color. The purpose is to mix the different luminous powder with E L to have a different color mixing effect. Another difference is that a luminous positive-type electroluminescent (EL) element is provided in the color. The surface electrode layer is superposed with a majority of the light-emitting layers and an electromotive layer is superposed. The inducer is driven by alternating current, and The luminescence is vibrated, and then the outer periphery of the luminous layer is mixed with an insulating encapsulation layer or blended or combined with a luminous layer that absorbs and reserves light and is composed of most luminous powders.
