Abstract

The invention relates to the field of optical technology, and discloses an optical structure, a control method thereof, and a display device. The optical structure includes a dimming unit, an optical sensing unit and a control unit. The dimming unit is divided into at least two sub-regions, the optical sensing unit is used to obtain parameters related to the light intensity irradiating each sub-region of the dimming unit, and the control unit illuminates each sub-region according to The parameters related to light intensity control the light transmittance of the corresponding sub-area, so that the light transmittance of the optical structure can be automatically adjusted according to the light intensity without manual adjustment, which improves user experience. At the same time, the divisional control of the dimming unit can ensure that the light transmittance of the entire dimming unit is the same to obtain a better user experience.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an optical structure, a control method thereof, and a display device. Background technique [0002] Polymer Dispersed Liquid Crystal (Polymer Dispersed Liquid Crystal, referred to as PDLC) is a mixture of low-molecular liquid crystals and prepolymers, and undergoes polymerization under certain conditions to form micron-sized liquid crystal droplets that are evenly dispersed in the polymer network. The dielectric anisotropy of liquid crystal molecules is used to obtain materials with electro-optic response characteristics. PDLC has two working states of scattering state and transparent state, and has a certain gray scale, so it has received extensive attention and has broad application prospects. [0003] The preparation process of PDLC devices is simple, and it has been widely used in large-area flexible displays, optical modulators, heat-sensitive and pressure-sensitive device...
