The graph of a relation of width.To have a display surface of 0～255 gray value (whole gray values are for 256 gray scales)
As a example plate, compare the dark stricture of vagina width of highest gray value 255 and intermediate grey values 128, find middle gray
The dark stricture of vagina width (such as 4 units) of the first dark stricture of vagina DF1 of value 128 is the first of highest gray value 255
2.6 times of the dark stricture of vagina width (such as 1.54 units) of dark stricture of vagina DF1.In the present invention, it is to study dark stricture of vagina
Relation between width and the visual angle uniformity and visual angle sustainment rate, by corresponding to the different gray value of adjustment
Dark stricture of vagina width ratio design, so that display device is can reach stable and be not easily susceptible to processing technology variation shadow
The preferable visual angle sustainment rate ringing.
The visual angle uniformity of display floater, can be defined as follows：
In z-axis angle theta=60 degree and trunnion axis angleUnder brightness (luminance) divided by z-axis
Angle theta=60 degree and trunnion axis angleUnder brightness.Wherein, brightness (luminance) refers to a light
The source unit interior luminous flux being sent of per area per solid angle in given directions.Therefore, visual angle is equal
Evenness can simply be represented with formula (1)：
The visual angle sustainment rate of display floater, then may be defined as：
The visual angle uniformity of the visual angle uniformity/highest gray value of intermediate grey values.
Wherein, intermediate grey values and highest gray value are worked as depending on the specification of the display floater of practical application,
Intermediate grey values are usually the half of whole gray values.For example, if its gray value of display floater of application is
0～63, then highest gray value is 63, and whole gray values are 64 gray scales, then intermediate grey values are 32.
If its gray value of display floater of application is 0～255, highest gray value is 255, and whole gray values are
256 gray scales, then intermediate grey values are 128.If its gray value of display floater of application is 0～1023,
Then highest gray value is 1023, and whole gray values are 1024 gray scales, then intermediate grey values are 512.
Therefore, to gray value be 0～255 display floater embodiment for, the visual angle of its display floater dimension
Holdup then can be represented with formula (2)：
The visual angle uniformity ... (2) of the visual angle uniformity/255 gray value of 128 gray values
Refer to Fig. 5, it illustrates dark stricture of vagina width ratio in one embodiment of the invention, the regarding of intermediate grey values
The graph of a relation of the angle uniformity, the visual angle uniformity of highest gray value and visual angle sustainment rate.Wherein, dark stricture of vagina
Width ratio is that the dark stricture of vagina width of intermediate grey values (such as 128) is dark divided by highest gray value (such as 255)
Stricture of vagina width, left side y-axis coordinate values are intermediate grey values and the visual angle uniformity of highest gray value, and the right
Y-axis coordinate is then visual angle sustainment rate (the visual angle uniformity of intermediate grey values and highest gray value is divided by).
As shown in figure 5, when dark stricture of vagina width ratio is less than 2.1, the amplitude of variation of visual angle sustainment rate is very big；And
In dark stricture of vagina width ratio after more than 2.1, for example between about 2.1～about 3.0 when, visual angle sustainment rate is then tieed up
It is fixed to keep steady.Therefore, it is more than 2.1 for example between about 2.1～about 3.0 interval in dark stricture of vagina width ratio, be
It is not readily susceptible to the stable region of processing technology impact.And secretly stricture of vagina width ratio is higher, the opening of this pixel
Rate is lower, and the upper limit of therefore dark stricture of vagina width ratio selects to be considered according to the aperture opening ratio of actual pixels,
For example when dark stricture of vagina width ratio is more than 3.0, dark stricture of vagina is wide, and the aperture opening ratio of pixel is low, therefore
May be selected about 3.0 is higher limit.
In addition, for the display floater with chromatic filter layer, taking the trichroism sub-pixel of RGB as a example, by
The sharpest for green in human eye, green sub-pixel impact pixel penetrance is maximum, therefore in Application Design
Upper hope can improve the penetrance of green sub-pixel.And penetrance can be subject to dark stricture of vagina widths affect, dark stricture of vagina width
Degree is narrower, and to face penetrance higher.Fig. 6 illustrates the trichroism sub-pixel of RGB of display floater in an embodiment
Dark stricture of vagina width corresponding in different gray values.Application embodiments of the present invention make green sub-pixel
Centre during high gray value dark stricture of vagina width (first dark stricture of vagina DF1 width) reduces, to obtain high-high brightness,
And then improve its penetrance.Therefore, in one embodiment, produce secretly when light passes through pixel region PX
The first dark stricture of vagina DF1 and the second dark stricture of vagina DF2 of stricture of vagina, such as earlier figures 3A, Fig. 3 B, pixel region PX are
During green sub-pixel, in highest gray value, the first dark stricture of vagina has the dark stricture of vagina width of the first green, pixel region
When PX is red sub-pixel, in highest gray value, the first dark stricture of vagina has the first red dark stricture of vagina width, as
When plain region PX is blue sub-pixels, in highest gray value, the first dark stricture of vagina has the first blue dark stricture of vagina width
Degree, wherein, the dark stricture of vagina width of the first green is less than the first red dark stricture of vagina width, and the dark stricture of vagina width of the first green is little
In the first blue dark stricture of vagina width.
