Abstract: A wavelength conversion element including a substrate, a blocking wall structure layer, and a wavelength conversion layer is provided. The blocking wall structure layer is disposed on a surface of the substrate and defines multiple microgrooves. Reflectivity of the blocking wall structure layer is in a range of 1% to 99%. The wavelength conversion layer is disposed in the microgrooves and includes multiple wavelength conversion particles. A height of the blocking wall structure layer along a normal direction of the surface of the substrate is greater than a height of the wavelength conversion layer along the normal direction of the surface of the substrate. A backlight module adopting the wavelength conversion element is also provided.

Abstract: An electronic device is provided, and the electronic device includes a main body, an actuating module, a first linkage, a first casing and a thermal dissipating module. The actuating module is disposed in the main body. One side of the first linkage is connected with the actuating module. The first casing is connected with the other side of the first linkage. One side of the thermal dissipating module is disposed at the main body and the other side of the thermal dissipating module is disposed at the first casing. The actuating module controls the first linkage to rotate to separate the first casing from the main body so that the thermal dissipating module is exposed from the main body and the electronic device is switched from a closed state to an open state.
