BOE’s latest intelligent dimming scheme can control the rotation of dye molecules to change the transmittance under the voltage drive, so as to realize the continuous adjustment of light and dark state. Compared with other dimming schemes, BOE intelligent dimming window has the advantages of high permeability, low power consumption and fast response. It has the effect of sound insulation, heat insulation and UV protection when combined with the industrialized window scheme. It is especially suitable for passenger car skylight and side window scenes, and can be well integrated into the application scenarios of passenger car intelligent cockpit. At present, the conventional dimming glass schemes on the market include PDLC (polymer dispersed liquid crystal), EC (electrochromic) and SPD (suspended particles). Although the technical indicators have their own advantages and disadvantages, their overall functions can not match the market demand perfectly, so they have not been widely used. It is understood that PDLC (polymer dispersed liquid crystal) dimming glass is transparent when power is applied, and it is foggy when power is off. Due to the high haze, PDLC’s application scenarios are limited. It is suitable for meeting room partition and cannot be widely used in automobile glass. < p > < p > EC (electrochromic) principle is redox reaction to achieve color change and dimming, but the response speed is slow (~ 5min / m2), and the larger the glass size, the slower the color change, which is prone to uneven color change. < / P > < p > the working voltage of SPD (suspended particle) dimmer glass is as high as 110V, so it is worried about the safety risk, so its application in the window glass is greatly restricted. < / P > < p > among them, the skylight dimming window is based on BOE liquid crystal dimming technology, adapts to the free-form surface design of the roof skylight, and supports the whole or partition dimming. It has excellent heat insulation performance, can replace the traditional sunshade, and also supports touch control, voice control and other control methods. < / P > < p > the side window dimming window supports dimming of the whole glass or partition, realizing the free control of light; at the same time, the BOE transparent display technology is integrated to realize the interaction between people and vehicles.
