Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
As described in the background art, (human eye is perpendicular to display panel there are positive visual angle for display panel in the prior art
Visual angle when light-emitting surface) under the white light that shows can show different degrees of colour cast under non-positive visual angle so that non-positive visual angle (people
Visual angle when eye is not orthogonal to the light-emitting surface of display panel) under display effect the problem of being deteriorated.Through inventor the study found that going out
The reason of existing above problem, is that white light is mixed by the light of three kinds of colors of red, green, blue, and white light is under different angle
Be from the amount of light of display panel it is certain, different colours light with visual angle increases (human eye from perpendicular to display panel to parallel
It is gradually increased in display panel light-emitting surface visual angle) brightness decay speed is inconsistent.For example, red light declines as visual angle increases brightness
Subtract comparatively fast, and blue light is slower with visual angle increase brightness decay, so that the white picture under positive visual angle is at non-positive visual angle
The partially blue phenomenon of lower appearance.And in conventional display panels, upper and lower surface of the pixel on the thickness direction of display panel is usually
Plane, so that the wide part that pixel issues is emitted along the direction perpendicular to display panel light-emitting surface, small part light edge and light out
Face vertical direction at an angle (not including 0 degree) direction outgoing so that the light for being able to enter human eye under non-positive visual angle has
It limits, i.e., the feux rouges, green light and blue light that human eye is able to enter under big visual angle are all less, and as described above, and feux rouges increases with visual angle
The big brightness rate of decay is very fast, more exacerbates color offset phenomenon.
