Abstract
The invention discloses a polarizing-shutter mixed type 3D display device, and belongs to the field of photoelectric technology. The 3D display device is formed by a display adapter, an LCD display panel, a light source A, a light source B, and a synchronizer. An image output end of the display adapter is connected with a signal input port of the LCD display panel, and an output end of the display adapter is connected with the synchronizer. The synchronizer comprises an inverter X, an inverter Y, and an inverter Z. The light source A is connected with the signal output end of the display adapter through the inverter X, and the light source B is connected with the signal output end of the display adapter through the inverter Z and the inverter Y. The light source A and the light source B are on a back side of the LCD display panel. When the display device is working, signals sent to the LCD display panel by the display adapter comprise video signals of each frame and signals to mark odd-even frames. Thus, when an odd-even signal line is zero, the light source A gives out light and the light source B goes out, and when the signal is one, the light source B gives out light and the light source A goes out. The 3D display device can ensure displayed resolution and high-quality 3D effect.
Description
Technical field
The invention belongs to field of photoelectric technology, relate to a kind of 3D rendering display unit.
Background technology
Existing have the 3D lcd technology of glasses can be divided into two types basically: fast gate-type and polarization type.
Fast gate-type 3D technology has ghost few, and film source is abundant, and image quality is good; Can keep the film original resolution, advantages such as technology maturation, but cost is expensive; Especially each user need wear electronic shutter glasses that involve great expense, and the 3D glasses that each manufacturer releases can not be general.Fast in addition gate-type 3D glasses are electronic equipment, and eyeglass is made by liquid crystal layer especially, though power is all little, also is certain to produce radiation, adds glasses and is close to eyes, wears for a long time and possibly damage human eye.Simultaneously, this technology also has the flicker problem, brightness discounting problem, and main is the operation principle that is limited to the 3D glasses, is easy to produce " Crosstalk phenomenon ", causes image fog, influence is watched.
Polarization type is divided into initiatively two kinds of polarization types and passive polarization type, and its characteristics do, does not have the scintillation of fast gate-type, and transmitance is high, and limit at no visual angle, and cost is low, and no electronic component is radiationless.But being passive polarization type vertical resolution drop by half, luminance loss, its shortcoming causes being difficult to realize full HD veritably resolution 3D image, and owing to polarisation principle picture brightness incurs loss, so require very high to display device.Initiatively polarization type then needs two display panels, and cost is too expensive.
Summary of the invention
It is high that the technical problem that the present invention will solve provides a kind of image resolution ratio, and the low hybrid 3D display unit of polarisation shutter of cost.
The scheme of technical solution problem of the present invention is to adopt display adapter, LCD display panel, light source A, light source B and synchronizer to constitute the hybrid 3D display unit of polarisation shutter; The display adapter output end of image connects the signal input port of LCD display panel; The display adapter signal output part connects synchronizer; Synchronizer is made up of inverter X, inverter Y and inverter Z, inverter Y and inverter Z series connection, and light source A connects the display adapter signal output part through inverter X; Light source B is connected the display adapter signal output part through inverter Z with inverter Y, and light source A and light source B are at the back side of LCD display panel.During work; The signal that display adapter is delivered to the LCD display panel comprises the vision signal of each frame and the signal of sign parity frame; Wherein the parity frame signal is 0 and 1 alternately to transmit, and for example this signal is that what transmitted in 0 o'clock is even frame, and this signal is that what transmitted in 1 o'clock is odd-numbered frame. this holding wire is picked out the driving of an inverter (this inverter reality is as analog line driver) as light source A; Pick out of the driving of the inverter of two series connection again as light source B; When the parity signal line was 0, then the luminous B of A extinguished like this, and the luminous A of B extinguishes when this signal is 1.The field synchronization device is connected with display device, has guaranteed display during odd field shows, light source A is luminous, and light source B extinguishes, and equally also guarantees display during even field shows, light source B is luminous, and light source A extinguishes.When watching the 3D film, only need be with common polarised light glasses.
Because right and left eyes content Alternation Display is on display panels; Need switch two light sources simultaneously; So the present invention and the same problem that also has flicker of fast gate-type 3D technology are so the field frequency that requires to show reaches 120HZ so that flickering drops to the very low lower cost of manufacture that has simultaneously.
The simultaneously compatible 2D program of the present invention shows that when the content of input was not distinguished right and left eyes, content displayed can not switched even light source also will normally switch, and the 2D image shows so can obtain clearly, and this moment, spectators need not to wear polaroid glasses.
If this display is used for computer, then need video card that an odevity field index signal line is provided, the backlight of display goes to drive two light source alternations according to this signal.
If this display is used for television system, then need the TV signal the inside to comprise the parity field level signal, TV receiver circuit can be separated this signal simultaneously, to drive two light source operate as normal.
Effect of the present invention is: adopt polaroid glasses with low cost; The 3D Display Technique that adopts polarisation to combine with shutter; Can guarantee the resolution that shows to guarantee high-quality 3D effect, avoid adopting expensive fast gate-type glasses; Avoid initiatively two LCD displays of polarization type employing simultaneously, reduced cost.
