Abstract
The invention provides a transparent liquid crystal display panel, which comprises a first substrate and a second substrate which are oppositely arranged, wherein the first substrate is configured toenable light incident into the first substrate to be transmitted through reflection; a liquid crystal layer positioned between the first substrate and the second substrate; a first grating layer positioned between the liquid crystal layer and the first substrate, wherein the first grating layer comprises a plurality of first gratings arranged in an array; a first electrode layer arranged between the first grating layer and the liquid crystal layer, wherein the first electrode layer includes a plurality of first electrodes arranged in an array; a second electrode layer positioned between the liquid crystal layer and the second substrate, wherein the forward projection of each first grating on the first substrate at least partially covers an area between the forward projections of two adjacent first electrodes on the first substrate, the liquid crystal layer is configured to form a plurality of liquid crystal prisms arranged in an array when a voltage is applied to the plurality of firstelectrodes and the second electrode layer respectively, so that light emitted from the plurality of liquid crystal prisms is reflected on the second substrate and returned to the plurality of liquidcrystal prisms.
Description
technical field [0001] The invention relates to the field of liquid crystal display technology, and in particular to a transparent liquid crystal display panel, a driving method thereof, and a transparent liquid crystal display including the same. Background technique [0002] Due to the advantages of high color gamut, thinness, short response time, etc., liquid crystal displays have been widely used in various applications. However, for a conventional liquid crystal display, in order to obtain the modulation of the polarization state of light, for example to realize the display of different gray scales, it is necessary to set polarizers on the upper and lower sides of the liquid crystal layer, such as two polarizers whose polarization directions are perpendicular to each other. piece. Therefore, when such a liquid crystal display is applied in the technical field of transparent display, due to the existence of these two polarizers, more adverse absorption of ambient light ...
