Abstract

A wavelength conversion element comprises a substrate and a wavelength conversion layer. The wavelength conversion layer is disposed on the substrate. The wavelength conversion layer comprises a firstinorganic adhesive and a wavelength conversion material, wherein the wavelength conversion material are mixed in the first inorganic adhesive. The first inorganic adhesive comprises a first alcohol-soluble inorganic adhesive or a first water-soluble inorganic adhesive. The invention further provides a projection device using the wavelength conversion element and a manufacturing method of the wavelength conversion element.

Description

technical field [0001] The present invention relates to a display device, in particular to a wavelength conversion element, a projection device using the wavelength conversion element and a manufacturing method of the wavelength conversion element. Background technique [0002] The types of light sources used in projection devices have evolved from ultra-high pressure mercury lamps (UHP lamps) and light emitting diodes (light emitting diodes, LEDs) to Laser diode (laser diode, LD). [0003] At present, the cost of high-brightness red laser diodes and green laser diodes is too high. In order to reduce costs, blue laser diodes are usually used to excite the phosphors on the phosphor wheel to generate yellow and green light, and then pass through the color wheel (filterwheel) The required red light is filtered out, and then combined with the blue light emitted by the blue laser diode to form the three primary colors of red, green and blue required for the projection screen. ...
