Company patents

HEFEI BOE DISPLAY TECHNOLOGY CO., LTD.

HEFEI BOE DISPLAY TECHNOLOGY CO., LTD's patent strategy reveals a strong, albeit shifting, focus on display technologies, with Liquid Crystal & Optical Modulators comprising 58.9% of its portfolio and Display Drivers 33.3%, despite a notable decline in patenting activity across both categories so far in 2026 (down 75.0% and 64.3% respectively). Surprisingly, while its core display categories are seeing a recent slowdown, the company showed an emerging interest in Semiconductor Diodes & Transistors, with 11 patents filed in 2025 and 2026 after no activity in prior years, suggesting a strategic pivot towards underlying semiconductor components.

Dimming window comprising a transparent conductive layer having a bonding region and method for manufacturing the same

Filed:2021-04-23Pub:2025-06-10
Applicant:Hefei BOE Display Technology Co., Ltd.

The present disclosure provides a dimming window and a method for manufacturing the same. The dimming window includes a cell defined by a first substrate and a second substrate, where at least one side edge of the first substrate exceeds an outside of the second substrate, and a part of the first substrate that exceeds the second substrate serves as a single substrate region; a first transparent conductive layer on one side of the first substrate facing the second substrate; a second transparent conductive layer on one side of the second substrate facing the first substrate; and a liquid crystal layer between the first substrate and the second substrate. The first transparent conductive layer includes a bonding region at the single substrate region; and a pattern of the bonding region includes a first sub-region and a second sub-region which are separated from each other; the first sub-region is in a binding connection with a first driving circuit which drives the first substrate, and the second sub-region is in a binding connection with a second driving circuit which drives the second substrate; and the second sub-region is in conductive connection with the second transparent conductive layer. The dimming window and the method for manufacturing the same in the present disclosure can eliminate the need to drill holes in substrates, reduce process difficulty, reduce time consumption and improve product yield.
