Display device based on electric control dimming

Abstract

The invention discloses a display device based on electric control dimming, which comprises an electric control dimming liquid crystal cover plate, the inner side of the electric control dimming liquid crystal cover plate is provided with a beam splitter prism with a right triangle cross section, and a light absorption surface facing an inclined surface is placed at the bottom of the inclined surface adjacent to and controlling the beam splitter prism, a light source is further arranged on the side, away from the electric control dimming liquid crystal cover plate, of the beam splitter prism, and the electric control dimming liquid crystal cover plate is further connected with an electric control dimming component, and the electric control dimming component is used for controlling the electric control dimming liquid crystal cover plate to be in an overall transparent state when the light source is turned off, so that external light entering the electric control dimming liquid crystal cover plate is reflected to the light absorption surface through the beam splitter prism and is absorbed. According to the display device based on electric control dimming, the effect of integrated black dynamic display and screen-off aesthetics can be achieved on the basis that the display energy consumption is reduced and the display device is more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted display equipment, and in particular relates to a display device based on electronic control dimming. Background technique [0002] With the advancement of science and technology, the amount of carbon emissions caused by human activities is also increasing, and the earth's ecology is facing threats. At present, my country has entered a new stage of development. Actively promoting carbon peaking and carbon neutrality will help improve the internationalization of industrial technology. Competitive, green and low-carbon products are the future trend. [0003] Most of the existing integrated black beacon products use black ink coating + transparent material / black material as the cover plate, and use high energy consumption LED and other light sources for lighting for a long time. This is to achieve "integrated black" and " The purpose of "screen-off aesthetics" is that when the product is powe...

Problems solved by technology

[0003] Most of the existing integrated black beacon products use black ink coating + transparent material / black material as the cover plate, and use high energy consumption LED and other light sources for lighting for a long time. This is to achieve "integrated black" and " The purpose of "screen-off aesthetics" is that when the product is powered off or turned off, the display area / beacon character area of ​​the display screen and the surrounding black non-luminous area form a consistent color to produce an integrated effect. Visible, To achieve this effect requires a substantial increase in power consumption of the product, resulting in a serious waste of energy and a very poor environmental protection effect
