The invention discloses a multifunctional liquid crystal writing board comprising a control circuit, a liquid crystal handwriting film and a background plate. The liquid crystal handwriting film and the background plate are stacked. The liquid crystal handwriting film includes a first base layer, a first conductive layer, a first liquid crystal layer, a second conductive layer and a second base layer that are arranged successively. The background plate includes a first polaroid, a third base layer, a third conductive layer, a second liquid crystal layer, a fourth conductive layer, a fourth base layer and a second Polaroid that are arranged successively. A light absorption axis of the first Polaroid is perpendicular to or is parallel to a light absorption axis of the second Polaroid. According to the invention, the multifunctional liquid crystal writing board can be used for imitation when the background plate is in a light transmitting state and can be used as a backboard when the background plate in a dark state. The user can switch imitation and backboard application modes by one key by the control circuit.
Description
technical field [0001] The invention relates to the field of liquid crystal display devices, in particular to a multifunctional liquid crystal tablet. Background technique [0002] Liquid crystal tablet is a device that relies on pressure to present handwriting. In order to better present handwriting, existing liquid crystal tablet generally includes a writing surface and a non-writing surface. Among them, the non-writing surface adopts a dark film to highlight writing. Handwriting on the surface. The function of the existing liquid crystal tablet is relatively single, and cannot satisfy the copying needs of some users at the same time. Contents of the invention [0003] The main purpose of the present invention is to propose a multi-functional liquid crystal tablet, aiming to solve the problem that the liquid crystal tablet in the prior art cannot meet the needs of writing and copying at the same time. [0004] In order to achieve the above object, the present invention...
