Abstract

The invention provides an optical component, an optical device, and an adjustment method for the optical device, and relates to the field of display technology. When the characteristic parameter attribute of the conversion film layer reaches the preset conversion threshold of the conversion film layer, the excitation film layer will excite the conversion film layer. The static water contact angle changes from a super-hydrophilic state to a super-hydrophobic state, which weakens the adhesion of water droplets attached to the conversion film layer, making them easy to roll, gather into large water droplets and slide down, fundamentally improving the fogging inside the closed space The problem. The optical component includes: a conversion film layer and an excitation film layer on the conversion film layer, wherein the conversion film layer performs reversible conversion between hydrophilic state and hydrophobic state according to specific parameters of the excitation film layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical assembly, an optical device and an adjustment method for the optical device. Background technique [0002] With the continuous development of science and technology, the needs of users are becoming more and more abundant. For example, in rainy days or when the outside temperature is low, the temperature difference between the inside and outside of the car is relatively large, which will cause the water vapor in the air in the car to be trapped in the windshield 101. The surface condenses to form small water droplets. Because the gravity of the small water droplets is small, and the windshield has a large adsorption force for the small water droplets, the small water droplets 102 become figure 1 The shape shown increases the contact area between the small water droplets and the windshield, which increases the friction force on the small water droplets, causing a large ...
