Abstract
The embodiment of the invention provides a light valve element and a liquid crystal display device. The light valve element comprises a first substrate and a second substrate which are oppositely arranged in parallel, transparent insulating layers are arranged on the opposite surfaces of the first substrate and the second substrate respectively, and a plurality of cylinders are arranged between the first substrate and the second substrate at intervals; a space formed between the first substrate and the second substrate is divided into at least one cavity by the cylinders, at least one laser device is arranged in each cylinder, and a lithium niobate film is laid on at least one part of the side surface of each cylinder along the laser emitting direction. According to the embodiment of the invention, the controllable particles in the liquid crystal display device can be conveniently controlled by utilizing the interaction between the laser device and the lithium niobate film through the photo-assisted virtual electric field micro-control technology, so that the switching between transmission-type display and reflection-type display is realized, and the control and utilization of a light source are facilitated. Therefore, the display effect and the display performance can be well improved, and the power consumption is low.
Description
Technical field [0001] The present disclosure relates to the field of display devices, and more particularly to a light valve element and a liquid crystal display device. Background technique [0002] The existing liquid crystal display device can be divided into a variety of transmissions, reflective, semi-transmissive, and more depending on the light source. Among them, the transmission liquid crystal display device generally transmits the substrate with the LED lamp as a backlight, the backlight transmitted by the backlight, and irradiates to the color film substrate to form an image; the reflective liquid crystal display device is an ambient light or a front light as a light source , A material having a good reflective performance is prepared on the display substrate, irradiated by ambient light or the front light to the display substrate to form an image; the semi-transmissive display device is a combination of the above, and can be on the array substrate. The reflection zon...
