Table body surface liquid crystal display TV and device realizing multiple identification

Abstract

The invention discloses a table body surface liquid crystal display (LCD) TV and device realizing multiple identification, comprising a transmissive type liquid crystal display (1), a transparent grating backing liner (3) on the lower surface of the transmissive type liquid crystal display, a semi-transparent optical microsphere diffusion membrane (2), an LED optical field module, a LCD driving device, an optical field box (15), a surface transparent touch table surface (4) and a multiple man-machine interaction identification device. Upper and lower transmission optical field space is made between the surface of the transmissive type liquid crystal display and the LED optical field module. A surface man-machine interaction device realizes identification of infrared images and human body biological characteristics by adopting the upper and lower transmission optical field space. The transmission optical field space is adopted to realize multiple touch and surface identification of man-machine interaction operation and multiple identification of bidirectional short-distance radio communication, etc. A table body TV box is arranged below the table body surface transparent table surface and is used for installing and fixing the optical field box, the LCD driving device and the surface man-machine interaction device, thereby realizing the table body surface LCD TV realizing multiple identification.

Description

technical field [0001] The invention relates to a table surface liquid crystal television, in particular to a multi-identification table surface liquid crystal display television and a device. technical background [0002] As we all know, the structural design of LCD TV is characterized by ultra-thin, but the backlight module of the liquid crystal display is very close to the liquid crystal display with almost no distance. A single flat-panel attribute, although touch can be realized in the use of human-computer interaction, but due to the limitation of the flat-panel display structure of LCD TVs, the human-computer interaction recognition technology of liquid crystal display is limited to resistance, capacitance, surface acoustic wave, and infrared sensing. Technology, due to the limitations of the flat panel display structure of LCD TVs, the surface of LCD TVs cannot use its own transmission characteristics to realize optical images of people or objects, human body feature...

Problems solved by technology

[0002] As we all know, the structural design of LCD TV is characterized by ultra-thin, but the backlight module of the liquid crystal display is very close to the liquid crystal display with almost no distance. A single flat-panel attribute, although touch can be realized in the use of human-computer interaction, but due to the limitation of the flat-panel display structure of LCD TVs, the human-computer interaction recognition technology of liquid crystal display is limited to resistance, capacitance, surface acoustic wave, and infrared sensing. Technology, due to the limitations of the flat panel display structure of LCD TVs, the surface of LCD TVs cannot use its own transmission characteristics to realize optical images of people or objects, human body feature biometrics, and multi-touch optical image recognition technology that is not limited by the number of touch points. Short-distance wireless communication identification, large-screen flat-panel LCD TVs are only used for viewing functions, which limits the functions of large-screen flat-panel LCD TVs, and does not have two-way recognition for small mobile handheld flat-panel LCDs in use. Short-distance wireless communication , the application of LCD TVs is limited due to the flat structure of LCD TVs
