Special survey tool measurement is crossed to obtain.Therefore, by way of realizing changing the bit phase delay amount of liquid crystal and turn blue module 10
It, only need to be during at box by way of controlling liquid crystal cell thickness without changing 100 existing production technology of display module
It realizes, such mode is simple to operation.
Except being turned blue in addition to module 10 by the way of changing liquid crystal bit phase delay amount to realize, optionally, combined with Figure 1 and Figure 2,
The module 10 that turns blue in the application can also realize by way of changing pixel transmittance area, the display module of the prior art
In 100, the glazed area of each sub-pixel is typically equal, and the embodiment of the present application increases the transparent surface of blue subpixels 113
Product so that the glazed area of blue subpixels 113 is more than the glazed area of red sub-pixel 111, the light transmission of blue subpixels 113
Area is more than the glazed area of green sub-pixels 112.
Specific to refer to Fig. 8, Fig. 8 show in the module that turns blue that the embodiment of the present application is provided showing for pixel unit
Be intended to, a pixel unit includes red sub-pixel 111, green sub-pixels 112 and blue subpixels 113, it is illustrated that box generation
The size of the open region of each sub-pixel of table, that is, glazed area, in embodiment illustrated in fig. 8, red sub-pixel 111, green
The height of 113 open region of pixel 112 and blue subpixels is respectively h1, h2 and h3, and width is respectively d1, d2 and d3, wherein h1
=h2=h3, d1=d2 ＜ d3, the glazed area of each sub-pixel are the product of above-mentioned height and the width, i.e. red sub-pixel 111
Glazed area be h1*d1, the glazed areas of green sub-pixels 112 is h2*d2, and the glazed area of blue subpixels 113 is h3*
D3, since h1=h2=h3, d1=d2 ＜ d3, therefore, the glazed area of blue subpixels 113 are maximum, the red and sub- picture of green
The glazed area of element 112 is equal.Increase the glazed area of blue subpixels 113 equivalent to increase being penetrated under the same conditions
Blue light amount, the intensity of blue light is enhanced, so that the module 10 of turning blue is whole partially blue, to make up blue light filter membrane 20
Blue light lacks caused by filtering out after excessive blue light, thus is conducive to improve display module 100 and shows partially yellow under white picture
Phenomenon.In the embodiment, red sub-pixel 111 and green sub-pixels 112 can be kept on the basis of existing display module 100
Glazed area it is constant, the mode for increasing the glazed area of blue subpixels 113 forms the module 10 that turns blue, alternatively, appropriate drop
The side of the glazed area of low red sub-pixel 111 and green sub-pixels 112 and the suitably glazed area of increase blue subpixels 113
Formula forms the module 10 that turns blue, and the application is to this without specifically limiting.
Optionally, Fig. 9 show the another kind of a pixel unit in the module that turns blue that the embodiment of the present application is provided and shows
It is intended to, in the embodiment, the height of 113 open region of red sub-pixel 111, green sub-pixels 112 and blue subpixels is respectively
H1, h2 and h3, width are respectively d1, d2 and d3, wherein h1=h2=h3, d1 ＜ d2 ＜ d3, the glazed area of each sub-pixel are
The product of above-mentioned height and the width, the i.e. glazed area of red sub-pixel 111 are h1*d1, the glazed area of green sub-pixels 112
Glazed area for h2*d2, blue subpixels 113 is h3*d3, due to, h1=h2=h3, d1 ＜ d2 ＜ d3, therefore, three seeds
The glazed area of pixel is different, the glazed areas of green sub-pixels 112 be more than the glazed area of red sub-pixel 111 and
Less than the glazed area of blue subpixels 113.In the actual production process, the glazed area of red sub-pixel 111 can be kept not
Become, the appropriate glazed area for increasing green sub-pixels 112 and blue subpixels 113, and the glazed area of green sub-pixels 112
Increase amplitude is smaller, and the increase amplitude of the glazed area of blue subpixels 113 is larger；Certainly green sub-pixels 112 can also be kept
Glazed area it is constant, the appropriate glazed area for reducing the glazed area of red sub-pixel 111 and increase blue subpixels 113；
This two ways can increase the glazed area of blue subpixels 113 so that the amount of the blue light of transmission increases, and then increases blue
The light intensity of light so that the module 10 that turns blue turns blue, and is lacked with making up blue light caused by blue light filter membrane 20 filters out after excessive blue light,
Improve display module 100 and shows partially yellow phenomenon under white picture.
It should be noted that in Fig. 8 and embodiment illustrated in fig. 9, the glazed area of each sub-pixel representated by box it is big
It is small not to represent actual size, only schematically illustrate.In addition, in Fig. 8 and embodiment illustrated in fig. 9 each sub-pixel open region height
Spend it is identical, it is of different size so that difference occurs in glazed area, can also be by the width of each sub-pixel open region in addition to such mode
Degree is set as identical, and by different height designs, to make, glazed area reaches different or length and width may be designed as
Difference, the application is to this without specifically limiting.
