Abstract
A light source module includes a light adjusting element including a first substrate, a second substrate and a fluid layer, the fluid layer includes polar fluid, the first substrate includes a light guide layer, a first electrode layer and a dielectric layer, the dielectric layer is in contact with the fluid layer, a refractivity of the dielectric layer is equal to that of the light guide layer, a refractivity of the polar fluid is greater than or equal to that of the dielectric layer, the light adjusting element incudes control regions corresponding to first electrodes included in the first electrode layer one by one, a second electrode layer is provided in the first or second substrate, a control electric field is formed between the first electrode and the second electrode layer to control hydrophilicity and hydrophobicity of the polar fluid on a surface of the dielectric layer.
