Liquid crystal polarization type illumination lamp with invisible cue word function

Abstract

The invention discloses a liquid crystal polarization type illumination lamp with an invisible cue word function. The liquid crystal polarization type illumination lamp comprises a light source, a liquid crystal panel, a cue word subtitle signal generation module, a liquid crystal panel driving module, a lens module and a piece of polarized glasses. The cue word subtitle signal generation module is used for converting cue words into subtitle signals. The liquid crystal panel driving module is connected between the cue word subtitle signal generation module and the liquid crystal panel. The liquid crystal panel driving module is used for transmitting the subtitle signals generated by the cue word subtitle signal generation module to the liquid crystal panel. Light generated by the light source passes through the liquid crystal panel and is amplified through the lens module and projected to an imaging plane to form a lighting area on the imaging plane. A user can wear the polarized glasses to observe the cue words in the lighting area formed on the imaging plane. If not wearing the polarized glasses, the user cannot see the cue words. The liquid crystal polarization type illuminationlamp with the invisible cue word function is reasonable in design, convenient to use, capable of serving as a common illumination lamp and capable of achieving the cue word function and has no influence on audiences.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a lighting fixture with invisible teleprompter function. Background technique [0002] When TV newscasters broadcast news, they usually need the help of a teleprompter to broadcast news releases, which can reduce the burden of the host and improve the quality of the broadcast program, but this teleprompter can only be used for programs without audiences on the spot In general, it can only be used in news program broadcasts; however, for other types of programs, the host usually needs to memorize a large number of commentaries, series words, etc. when hosting the program, and it is very difficult to memorize all of them. Therefore, a device to assist memory is also needed, but the host needs to face the audience directly, and the usual teleprompter cannot be used. Take a look at the content of the card in your hand from time to time. Doing so will affect the effect of the show to a certain e...

[0002] When TV news announcers broadcast the news, they usually need the help of a teleprompter to broadcast the press release, which can reduce the burden on the host and improve the quality of the broadcast program, but this kind of teleprompter can only be used in programs with no audience on the spot In general, it can only be used in the broadcast of news programs; however, for other types of programs, the host usually needs to remember a large number of commentary words, concatenated words, etc. when hosting the program, and it is very difficult to memorize them all. Therefore, a memory-assisting device is also needed, but the host has to face the audience directly, and the usual TV teleprompter cannot be used. The teleprompter method commonly used now is generally that the host uses a card in hand. Take a look at the content of the card in your hand from time to time, this will affect the effect of the program to a certain extent
