A liquid crystal display (LCD) component and an electronic device are provided. The LCD component may include: an upper substrate; a lower substrate arranged in parallel with the upper substrate; a liquid crystal layer interposed between the upper substrate and the lower substrate; an upper polarizer attached to a surface of the upper substrate which is not adjacent to the liquid crystal layer; and a lower polarizer attached to a surface of the lower substrate which is not adjacent to the liquid crystal layer; a control chip; and at least one optical proximity sensor arranged between the upper polarizer and the lower polarizer, and each optical proximity sensor is electrically connected with the control chip respectively.
