Glasses and Freestyle 2-in-1 Stereo TV

Abstract

The invention discloses a spectacle type and free type two-in-one stereoscopic television set which comprises a mainboard of a television set, a data processing circuit, a driving circuit of a liquid crystal grating, the liquid crystal grating, a display liquid crystal driving circuit, a display liquid crystal screen and a spectacle synchronous transmitter. The liquid crystal grating can work in a passive mode of a transparent glass mode or an active mode of a slit grating mode under the control of the driving circuit of the liquid crystal grating; the mainboard of the television set is further used for outputting spectacle synchronous signals to the spectacle synchronous transmitter and outwardly transmitting the spectacle synchronous signals, so that 3D (three-dimensional) spectacles can receive the synchronous signals under the control of the main board of the television set, left-eye images can be seen an observer via the left eye, and right-eye images can be seen by the observer via the right eye. The spectacle type and free type two-in-one stereoscopic television set has the advantages that the spectacle type and free type two-in-one stereoscopic television set not only has merits of low crosstalk and good 3D effects when spectacle type 3D television sets are used for 3D experience, but also has a merit that users do not need to wear spectacles when watching free type 3D television sets, and the problem of impaired image resolution due to lenticular grating films adhered to the existing free type 3D television sets can be solved.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a two-in-one stereoscopic TV set of glasses type and free type. Background technique [0002] There are currently two types of stereoscopic displays or televisions on the market, one is glasses-style stereoscopic displays, and the other is freestyle (ie, glasses-free) stereoscopic displays. The glasses-type stereoscopic display needs to wear glasses to experience the 3D effect, which is very inconvenient, but it has the advantages of small crosstalk and good stereoscopic effect when experiencing 3D. However, the free-style stereoscopic display can experience 3D effect without wearing glasses, but has the disadvantages of large crosstalk and poor stereoscopic effect. [0003] In addition, most of the free-style stereoscopic displays on the market adopt the method of sticking film, that is, a film called lenticular grating is pasted on the liquid crystal display surface. This film w...
