Abstract

The application provides mobile terminal equipment and a back cover component and a display screen component thereof. The mobile terminal equipment includes the back cover component and/or the displayscreen component. The back cover component includes a transparent substrate and a liquid crystal light-adjusting film disposed on one of surfaces of the transparent substrate. The liquid crystal light-adjusting film includes two conductive films and a liquid crystal layer disposed between the two conductive films. Voltage between the two conductive films can be adjusted according to a control signal of the terminal equipment to change light transmittance of the liquid crystal layer, and mutual switching of the back cover component of the mobile terminal equipment between transparency and hazedegrees is realized. The display screen component includes a display screen, a liquid crystal light-adjusting film and a light-supplementing lamp. The liquid crystal light-adjusting film is disposedat a position where an image sensor of the mobile terminal equipment directly faces. The light-supplementing lamp is used for carrying out light-supplementing for the liquid crystal light-adjusting film to optically shield the image sensor to enable an image sensor area to achieve a hiding effect when the image sensor stops working.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201811298327.6 and the application title "Mobile terminal equipment and its rear cover assembly and display assembly" submitted to the China Patent Office on November 02, 2018, the entire content of which is incorporated by reference incorporated in this application. technical field [0002] The embodiment of the present application relates to a mobile terminal device and its back cover assembly and display screen assembly, which belong to the technical field of communication equipment. Background technique [0003] With the development of economy and technology, consumers not only hope that the performance of mobile terminal devices such as smart phones, tablet computers and wearable devices will be better and better, but also put forward higher and higher requirements for the appearance of these mobile terminal devices. No matter the shell of the existing mobile termin...
