Described light source comprises constant-flow driver and full-color light-emitting diode, the pulse width modulating signal that described constant-flow driver is exported for receiving driving signal output interface, and export the second drive full-color light-emitting diode.
Wherein, the flicker frequency of light source is according to the modulating frequency of design Auto-matching display system shutter glasses, and light source scintillation frequency is the integral multiple of shutter glasses modulating frequency, and is that twice is with upper frequency; And the frequency multiple of light source, brightness, colourity, saturation, light distribution mode can arrange by control signal input terminal and the display system display screen terminal of display system according to demand.
As preferably, described full-color light-emitting diode forms and is fixed on display system display screen terminal dorsal edge place by organize independently full-color light-emitting diode working group more, it is distributed in the upper and lower, left and right Si Ge edge at the display system display screen terminal back side, direction of illumination is spent left and right to extrinsic deflection 45 on the basis of vertical display surface, and shine out through one deck scattering sheet, can, according to demand by organizing the independently setting of full-color light-emitting diode working group, form the multiple distribution mode of not sharing the same light more.
The beneficial effect of technique scheme of the present utility model is as follows: the modulating frequency of automatically identifying shutter glasses by being integrated in the lighting device of shutter three-dimensional display system, produce the lighting environment light of frequency match, under the condition that ensures certain illumination light, eliminate the flickering that conventional environment light source may produce with shutter glasses interaction, alleviate better issuable visual fatigue while watching for a long time shutter stereo display content, avoided vision impairment.In addition; the utility model is except frequency match is to reach the object of science vision protection; user can be by the man-machine interface of display system; according to demand with parameters such as fancy setting environment light frequency multiple, brightness, colourity, saturation, light distribution modes; thereby can build different environments by surround lighting, strengthen visual experience and visual experience.
