Description
Technical field
The present invention relates to field of display technology, more particularly, to a kind of true color Alpha all-pass channel display apparatus, with
And true color Alpha's full tunnel display methods.
Background technique
In computer graphics, each picture point can use tetra- parameter expressions of RGBA, and wherein RGB indicates that color is logical
Road, A (also referred to as α value, alpha value) indicate transparent channel (the also referred to as channel α, alpha channel).But Alpha at present
Channel exists only in theoretical and graphics calculations, temporarily can physically realize the display device of alpha channel not yet.
Current most display technologies are all opaque displays.
Even existing transparence display can not physically realize alpha channel.Existing transparence display technology, is only capable of
Presentation black transparent is shown or white clear is shown.
Black transparent shows, such as the self luminous display shielded or is incident upon image aobvious on transparent reflection medium
Show, this black transparent show the characteristics of be display content it is more transparent closer to black, closer to white it is opaquer.
White clear is shown, such as non-luminous light blocking is shielded thoroughly, and the unautogenous light of display medium itself needs background to have light
Source just can see that the display content on display surface, its main feature is that display content is more transparent closer to white, get over closer to black
It is opaque.
Because of the limitation of displaying principle, no matter black transparent is shown or white clear is shown, whole face can not be presented
Any transparent and opaque display of color.For example, shielding thoroughly in the self-luminous that black transparent is shown or reflecting on screen thoroughly, can not show close
Black system, and the light blocking that white clear is shown is shielded thoroughly, can not show near-white system.
Existing transparence display technology has the disadvantage that
1) color lacks.For example, shielding thoroughly in the self-luminous that black transparent is shown or reflecting on screen thoroughly, nearly black cannot be shown
System, and near-white system can not be shown by shielding thoroughly in the light blocking that white clear is shown.
2) transparency can not arbitrarily be changed under the premise of keeping color constant.
3) the transparent color of nature, such as the texture of glass and water can not be shown.
Therefore, the defect of existing display technology how is solved, it is required at present to do.
