Description
Technical field
The present invention relates to light emitting diode (LightEmittingDiode, LED) Display Technique field, specialRelate to a kind of LED display unit and system thereof that can show multi-view image signal.
Background technology
By light emitting diode (LED) with after walking crosswise the matrix of file and spreading all over, by driving each LED, canTo form LED display unit, and show the image of single view. Each LED wherein can be correspondingThe pixel of monochromatic (black and white) display unit, or the sub-pixel of colour display device.
But known LED display unit can not show the picture material of many views, do not using and can filterIn the situation of the glasses of light, cannot provide three-dimensional viewing effect for beholder. Described many views refer to two orTwo with last view. Show the picture material of many views, mean that people's eyes are likely watched respectivelyDifferent views or view combine, and then obtain the three-dimensional viewing effect of so-called bore hole.
People know, the pixel issued light of known two-dimensional display is guided to specifically, noSame direction, display unit can show multiple views, and then realizes three-dimensional viewing effect. But, makeThe ability that the pixel of known two-dimensional display possesses the light of transmitting different directions is difficult. By profitWith the various optical guidance elements including lens and grating, in recent years people start can be by LCDThe optics output of each pixel in plate (LCDpanel) is directed in different directions, and and then manufacturesGo out to show the display unit with three-dimensional viewing effect of multi-view image signal.
