Novel subway platform shielding and dimming liquid crystal glass image playing system

Abstract

A novel subway platform shielding and dimming liquid crystal glass image displaying system comprises a dimmable liquid crystal glass window, a dimming system control box, a player and multiple projectors. An infrared induction module is mounted at one end in a vehicle incoming direction. The infrared induction module is connected with the signal input end of the dimming system control box through an electric signal. The signal output end of the dimming system control box is respectively connected to the dimmable liquid crystal glass window and the player respectively through electric signals. The dimmable liquid crystal glass window is disposed on an advertising column on one side of a station. The projectors are arranged on the other side opposite to the advertising column. Video signals output by the player are connected to the projectors after passing a signal distribution amplifier and a circuit extender. The novel subway platform shielding and dimming liquid crystal glass image displaying system has the advantages of high resolution, large viewing angle, environment protection, no radiation, low energy consumption and the like.

Description

technical field [0001] The invention relates to a dimming liquid crystal glass image playing system, in particular to a novel subway platform shielding dimming liquid crystal glass image playing system. Background technique [0002] The shielding glass of the subway platform is generally made of transparent materials such as glass as the glass shield and movable door. In order to expand the utilization rate of subway resources, sometimes glass stickers are used or closed-circuit televisions are hung on the top to broadcast station or current news and other information. In order not to affect the line of sight of the passengers in the train and the passengers waiting on the platform when the subway train enters the station, these patterns and symbols are generally small and very simple. Some urban subways are already using subway shielding glass to place advertising light boxes and increase non-vehicle revenue. But the area where the advertising light box can be set up is ve...

Problems solved by technology

[0003] Although the closed-circuit television on the platform has the advantages of large amount of information and rich and colorful pictures, it is limited to the size of the monitor. Passengers who are far away from the monitor cannot see the content of the picture clearly, and the screen is too small to cause a strong visual impact on people; Secondly, limited by the installation location, the display can only be installed above the waiting room of the platform, and some passengers need to look up to watch it, causing inconvenience and affecting the publicity effect

[0004] Since the display device used is generally a liquid crystal display (LCD) or a plasma display (PDP), the display viewing angle and display size of the liquid crystal display are limited, and the plasma display is still technically imperfect. When a static image appears on the plasma screen for a long time In the same position, burns may occur. When turning on and off, the still image played before will be faintly displayed on the screen for a long time, which will have a certain impact on the effect of the displayed information.

Therefore, there is currently no technology that can better solve the contradiction between image playback effect, poor display position, and insufficient display area.
