Description
Technical field
The present invention relates to a kind of 2D, 3D display device based on space-time colour mixture technology, space-time colour mixture technology is based particularly on
The a variety of sequence display modes suitable for space-time colour mixture display device are proposed, 2D and 3D display patterns can be applied to simultaneously.
Background technology
Conventional cathode ray tube shows the liquid crystal display (LCD) of (CRT) and current popular, is realizing that colour picture shows
When, all employ spacing color mixed display pattern.This spacing color mixed display pattern is accounted for always in whole electronic display technology
According to leading position, but also there is its own shortcoming：Firstly, since the spacing color mixed sub-pixel for needing certain amount constitutes one effectively
Pixel, thus display device effective resolution be actual addressable resolution ratio 1/3 (correspondence three color informations show), or
Less (correspondence multicolour presentation of information).Secondly, in order to form red (R), green (G), blue (B) sub-pixel, liquid crystal display needs filter
Color chips (Color Filter)；One side colour filter cost accounts for the 20% of whole liquid crystal display device cost, on the other hand, filter
The light transmission rate of color chips only has 30% or so, i.e., absorbed in currently used liquid crystal display about 70% luminous energy
Amount, has huge energy waste.
At the same time, people are exploring application of the time mixing color in modern display always.One width colour picture is divided into
The width picture of red, green, blue three is referred to as (red, green, blue three), and is shown in order in a frame time, when frame frequency exceedes people
During the fusion frequency of eye, human eye perceives the complete colour picture of a width.Sequential colorization, which is shown, does not need sub-pixel, same
Under addressable resolution condition, display device effective resolution can bring up to original 3 times；Meanwhile, sequential colorization is shown not
Colour filter is needed, the light efficiency of liquid crystal display can be made to bring up to 3 times of original even more highs, while also a saving material cost.
But time mixing color there is also it is certain the problem of, mainly have of both reason：First, sequential colorization display needs higher refreshing frequency
Rate, if desired at least 180Hz field frequency, this was in the past, and liquid crystal response speed is difficult to meet to require；2nd, sequential colorization shows meeting
There is color separating phenomenon, have a strong impact on picture quality, in order to avoid color separating phenomenon, current Projection Display is employed
The field frequency of 600Hz even more highs.
How to make full use of spacing color mixed and color sequential operation advantage, evade respective shortcoming, develop high-quality low-power consumption and show
Show technology, as showing the focus that science and technology research structure is competitively studied in recent years.
Colour picture is realized using spacing color mixed technology more than existing shutter 3D Display Techniques, while in order to ensure left and right
The fusion of eye pattern picture, typically uses higher refresh rate.This causes when 3D is gone back under 2D patterns, and higher refresh rate becomes
Meaningless waste.Simultaneously as human eye can only once obtain general image information, resolution ratio under 3D display patterns significantly under
Drop.
The content of the invention
The technical problem to be solved：In view of the shortcomings of the prior art, the present invention proposes a kind of based on space-time colour mixture technology
Display device, solves the use colour filter cost height of simple spacing color mixed display device and haves the shortcomings that energy dissipation,
While solving power consumption under the resolution ratio and luminance-reduction of the 3D patterns under spacing color mixed technology, 3D display device 2D display patterns
The problem of waste.
Technical scheme：In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of display device based on space-time colour mixture technology, including liquid crystal display, the liquid crystal display include controllable
Array back unit and the liquid crystal layer being arranged in front of it, setting frame frequency are more than human eye fusion frequency, the controllable array back
The complete colour picture of one width is divided into many pictures with different color information so that liquid by unit over time and space
Crystal display has certain field frequency, and is shown in order by controllable array back unit and liquid crystal layer cooperation in a frame in
Come.
Controllable array back unit is briefly that one kind is arranged in matrix together by multiple luminescence units such as LED
A kind of form of light source, development in the field of business is quite ripe for the application of this arrangement mode, however, conventional application is only
Used as monochromatic source, matrix-addressable LED is also only in adjustment office of the consideration in synchronization selectivity of energy consumption
The light-source brightness in portion.And controllable array back unit not only can spatially can control local brightness used in this patent
Intensity, while can be modulated in colourity.I.e. each luminescence unit can with it is controlled send different colourities, brightness light.This
More than patent utilization controllable array back unit, during display, divides a secondary complete coloured image of original image source
For multiple fields, the control to controllable array back unit local chrominance and brightness is utilized so that comprising different between field and field
Colour information, by the field frequency more than human eye fusion frequency so that human eye experiences complete coloured image.Here because field is
Order display, that is, division in time is formed, while again because the luminescence unit in each field positioned at diverse location is pressed
Picture requirement according to its position sends corresponding light, that is, forms division spatially.So, from individually some luminous list
From the point of view of member, elapse over time, each field luminescence unit of correspondence can send different light；From the different positions in space
From the point of view of the multiple luminescence units put, in the same time, the luminescence unit of diverse location can send different light, and with
Time elapses, and each field of correspondence just forms different color informations.Such type of drive is maximum with existing application
Difference, that is, instead of single spacing color mixed technology, the present invention can without using or reduce and use colour filter, reduce due to
The huge energy loss that the light transmittance of colour filter is brought, meanwhile, utilize spatially modulated of controllable array back unit
Property, display process is reduced local brightness to greatest extent according to required coloured image, so as to reduce energy consumption.
More further, because complete coloured image is synthesized by different field sequences, every kind of sequence carries different color informations, so
More original three primary colours spatial color display based on RGB colour filters, the present invention is shown using many field sequential colors actually may be used
The colored display mode of multiple bases is realized, this can effectively expand display colour gamut in color display effect, so as to improve coloured silk
Quality and potentiality that color is shown.
Specifically, in the present invention, the controllable array back unit is made up of matrix form luminescence unit, it is each luminous single
Member is individually controlled and itself position is corresponding when needing to modulate different fields according to picture to display by addressing system
Colourity and brightness, certain gamut range is formed in a frame in so that controllable array back unit shows coloured image on the whole,
And elapse over time, the dynamic change of frame out is presented in controllable array back unit over time and space.
When actual use, the number of fields of a frame in is limited by the maximum refresh rate of display device, i.e., to ensure every complete coloured silk
The frame frequency of chromatic graph piece is higher than the fusion frequency of human eye.Preferably, the present invention discloses the complete colour picture of a frame being divided into 2
Field or 3 or 4 pictures, actual implementation are not limited to these three.
Further, in the present invention, when being divided into 2 pictures, in addition to be arranged on controllable array back unit and
Colour filter chip architecture between liquid crystal layer, the colour filter chip architecture includes 2 kinds of colour filters, and this 2 kinds of colour filters have different spectrum
Transmissivity distribution function.The increase of field ordinal number amount can not also be kept away while actually realizing that multiple bases show and expand and show colour gamut
The higher display refreshing frequency of the requirement exempted from.I.e. number of fields is fewer, and required display refreshing frequency is lower.But it is analogous to sky
Between in colour mixture, the color colour filter display patterns of RGB 3, if use time dither pattern expects certain gamut range, are at least needed
3 color informations are wanted to be merged.The complete colour picture of one frame is divided into the display mode of 2 color informations, not deposited
Actually inevitably there is the imperfect of color displays in the case of colour filter.The space-time colour mixture skill that the present invention is used
Art, a secondary complete color picture is not only carried out in time the segmentation of color information, using backlight control techniques in space
On also carried out the segmentation of certain color information, coordinate specific image algorithm, 2 can be realized to the full extent without using colour filter
The reduction of the coloured image of piece so that on the basis of preferable color display effect is realized, compared to it is spacing color mixed can be with
Reduced without using colour filter due to the energy consumption that colour filter is caused, display refreshing frequency is entered reduced compared to time mixing color again needed for
One step reduces energy consumption.Further, the present invention also proposes there is different spectral transmissions using 2 kinds in the case of 2
The colour filter of rate distribution function, so not only reduces a colour filter compared to the existing spacing color mixed technology of 3 color colour filter,
Energy consumption is reduced, while than simple time mixing color, using the spatial modulation of controllable array back unit, reducing required field
Frequently, got back while further reducing power consumption complete color representation.
Further, in the present invention, the supporting shutter type 3 D spectacles in addition to liquid crystal display, the shutter 3D
Glasses are according to the field frequency of liquid crystal display and as former modulation algorithm selecting switch frequency.Conventional shutter formula 3D glasses, are relied on
Right and left eyes receive the coloured image of full color information, form colour 3D figures in human brain using the parallax between right and left eyes image
Picture.The present invention is planted under the 3D display patterns of described space-time colour mixture display device, and the image that right and left eyes receive, which not only exists, to be regarded
The difference of poor information, while there is also the difference of color information.According to different field sequence patterns, right and left eyes receive specifically respectively
Colour information and parallax information, also depend on human eye while forming 3D senses and form complete coloured image.
Identical with traditional 3D sense generations, space-time colour mixture display device of the present invention is under 3D display patterns, the production of 3D senses
Life is also that the image information received by right and left eyes has parallax.But the characteristics of with based on space-time colour mixture of the present invention, right and left eyes
What is received at every is not complete coloured image, it is necessary to which shutter type 3 D spectacles receive different parallaxes respectively in control right and left eyes
While image, according to the display pattern of foregoing description display field sequential color information, control color information by human eye chronologically
Receive, so that while 3D senses are formed, fusion obtains complete coloured image.
As preferred, in the present invention, 2D display pattern end sequence patterns, respectively 2 are based on based on proposition before
Or 3 or 4 there is provided under 3D patterns for different field sequences, shutter type 3 D spectacles to entering the control models of the different fields of right and left eyes,
I.e. the switching frequency of shutter type 3 D spectacles and the field frequency of liquid crystal display are identical or into multiple proportion.Wherein, as preferred 3D
The switching frequency of mirror can be consistent with display field frequency, i.e., adjacent 2 are given left eye and right eye respectively.Display is sent per place
Except the difference of color information between the picture gone out, there is also parallax difference.The main function of 3D shutter glasses is according to specific
Field frequency the picture of the 2 secondary different colour informations with parallax difference between two is delivered to right and left eyes respectively.
Further, in the present invention, when being divided into 4 pictures, the switching frequencies of shutter type 3 D spectacles is except can be with
Keep the outer half that can also be the field frequency for liquid crystal display consistent with display field frequency, i.e., every two give respectively left eye with
There is parallax information in right eye, i.e. former two and rear two colour pictures being fused into respectively.
