Title:
ELECTRONIC DEVICE AND COVER PLATE THEREFOR, CONTROL METHOD AND CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/179457
Kind Code:
A1
Abstract:
Disclosed in the present application are a cover plate for an electronic device, an electronic device, a control method, a control apparatus and a readable storage medium. The cover plate comprises a first substrate, a first electrode layer, an electrochromic layer, a second electrode layer and a second substrate. When the cover plate is in a first time period, a first voltage difference is formed between the first electrode layer and the second electrode layer, and the color of the electrochromic layer changes under the action of the first voltage difference. When the cover plate is in a second time period, a pulse voltage difference is formed between the first electrode layer and the second electrode layer, and the first electrode layer and the second electrode layer form a fingerprint recognition structure under the action of the pulse voltage difference. The fingerprint recognition structure is arranged corresponding to a touch-control surface, the second electrode layer comprises a plurality of sensing pixel units, and when the cover plate is in the second time period, different sensing pixel units are used for sensing signal changes in different areas of the touch-control surface.
