310, and in some embodiments, the inward flange 310 of color emission layer 300 can be substantially right with the inward flange 210 of light shield layer 200
Together.Similarly, the outward flange 220 of light shield layer 200 can be adjacent to the outward flange 320 of color emission layer 300, the outward flange of color emission layer 300
320 can be with the substantial alignment of outward flange 220 of light shield layer 200.Consequently, it is possible to light shield layer 200 and color emission layer 300 are in euphotic cover plate
Orthographic projection on 100 inner surface 110 can overlap, and orthographic projection of the light shield layer 200 on inner surface 110 is without departing from color emission layer
The scope of 300 projection on inner surface 110.Therefore, light shield layer 200 can be covered by color emission layer 300 completely, so as to be beneficial to make
User sees the integral color that light shield layer 200 is presented jointly with color emission layer 300 in the side of euphotic cover plate 100, and prevents from using
Person sees the color of light shield layer 200, to help the first area 111 for reducing euphotic cover plate 100 and the colour-difference of second area 112
It is different.
The system of color emission layer 300 is clipped between light shield layer 200 and the inner surface 110 of euphotic cover plate 100.Specifically, mix colours
Layer 300 can also include first surface 330 and second surface 340.First surface 330 is relative with the system of second surface 340, inner edge
Edge 310 and outward flange 320 are to be adjacent between first surface 330 and second surface 340.First surface 330 compares second surface
340 closer to euphotic cover plate 100, for example, first surface 330 can contact the inner surface 110 of euphotic cover plate 100.Second table
Face 340, closer to light shield layer 200, can contact light shield layer 200 than first surface 330.Consequently, it is possible to color emission layer 300 can clip in
Between light shield layer 200 and euphotic cover plate 100.
In some embodiments, color emission layer 300 can be first formed to the firstth area of the inner surface 110 of euphotic cover plate 100
On domain 111, then, then light shield layer 200 is formed in color emission layer 300, color emission layer 300 is clipped in light shield layer 200 and printing opacity
Between cover plate 100.In some embodiments, the exemplary forming method of color emission layer 300 can be heavy using evaporation or sputter etc.
The material of color emission layer 300 is deposited on the inner surface 110 of euphotic cover plate 100 by product processing procedure.The exemplary formation side of light shield layer 200

The integral color of the side presentation of plate 100 can change.Consequently, it is possible to producer can be by the thickness of control color emission layer 300, to adjust
The color of first area 111.For example, touch control display device further includes a display panel S, display panel S and euphotic cover plate
100 respectively positioned at touch sensing layer 400 different both sides (such as：Opposite side or opposite side), and it is located at second area 112, if
Display panel S (such as organic LED panel) is that blueness is presented at non-working condition (that is, closed mode), then is
It is non-blueness to make color of the light shield layer 200 in some embodiments, that is, the color of light shield layer 200 is sat in LAB color spaces
Target b* values are positive, and user can still use the color emission layer 300 of specific thicknesses, such as color emission layer is niobium oxide, silicon nitridation
Thing or both, thickness are between 5 nanometers to 15 nanometers so that this color emission layer 300 is with light shield layer 200 in euphotic cover plate 100
Blueness is presented in the integral color that side is presented, that is, this integral color is what is born in the b* values of LAB color space coordinates, so as to
Help reduce first area 111 and the color distortion of second area 112, may be such that between first area 111 and second area 112
Aberration Δ E* be less than or equal to 3, preferably, the aberration Δ E* between first area and second area 112 is between 0.7 to 2.5
Between.It should be noted that Δ E*=[(Δ L*)2+(Δa*)2+(Δb*)2]1/2, wherein Δ L* represent LAB color spaces seat
The brightness value L * of mark difference, Δ a* represent the difference of the abscissa value (a* values) of LAB color space coordinates, and Δ b* represents LAB
The difference of the ordinate value (b* values) of color space coordinates.
Generally when reflectivity is larger, the region also can be larger in the L* values of LAB color space coordinates, in the prior art,
Light shield layer 200 and euphotic cover plate 100 are not provided with color emission layer 300, and the repeatedly structure of light shield layer 200 and euphotic cover plate 100 is to exterior light
The reflectivity of line is larger, and first area 111 can be higher than the L* values of second area 112 in the L* values of LAB color space coordinates, therefore the
Aberration between one region 111 and second area 112 also can be larger.In some embodiments of the present invention, color emission layer 300 with
The reflectivity of the lamination of light shield layer 200 is less than the reflectivity of light shield layer 200, consequently, it is possible to when ambient passes through euphotic cover plate
100 and when arriving at color emission layer 300, color emission layer 300 is relative to be not easy to reflect this ambient, the overall reflectivity of first area 111
It is relatively low so that first area 111 is reduced in the L* values of LAB color space coordinates and approached with the L* values of second area 112, so as to
Further reduce the aberration between first area 111 and second area.
In some embodiments, color emission layer 300 can be niobium oxide, silicon nitride or both.For example, color emission layer
300 material can be the combination of niobium pentaoxide (Nb2O5), silicon nitride (Si3N4) or both.Above-mentioned material can not only be beneficial to make
The integral color of color emission layer 300 and light shield layer 200 is different from the color of light shield layer 200, can also be beneficial to the face for making first area 111
Color changes according to the thickness change of color emission layer 300, and the reflectivity that can be also beneficial to color emission layer 300 is less than the reflection of light shield layer 200
Rate.In other words, color emission layer 300 can be the combination of niobium oxide layer, silicon-nitride layer or both, and first area is reduced with profit
111 with the color distortion of second area 112.In some embodiments, the combination of niobium oxide layer, silicon-nitride layer or both
Exemplary forming method can be evaporation or the depositional mode such as sputter, but the present invention is not limited thereto.
First area 111 and the control group that following table includes the touch control display device of the embodiment according to the present invention are tactile
Control reflectivity of the first area 111 under each visual angle, the a* values and b* values of LAB color space coordinates of device.
In the first area 111 of the touch control display device of control group, color emission layer is had no between euphotic cover plate and light shield layer,
And in the first area 111 of the touch control display device of embodiment of the present invention, there is toning between euphotic cover plate and light shield layer
Layer.As seen from the above table, the b* values of LAB color space coordinates of the non-visible area with color emission layer under each visual angle are negative value
(that is, b* ＜ 0), without color emission layer LAB color space coordinates of the non-visible area under each visual angle b* values for just
It is worth (that is, b* ＞ 0).It follows that color emission layer can be used to adjust the color of first area 111, further, color emission layer also can use
The color of non-visible area is adjusted to blueness (that is, b* values are the color of negative value), therefore even if positioned at the lower section of second area 112
Display panel under non-working condition when system blueness is presented, color emission layer still may help to reduce first area 111 and second area
112 color distortion.In addition, from upper table also, there is reflectivity of the first area 111 of color emission layer under each visual angle,
Reflectivity of the system less than the first area 111 without color emission layer under same view angle.It follows that the antiradar reflectivity of color emission layer
Characteristic may help to reduce the reflectivity of non-visible area, further to reduce the color between first area 111 and second area 112
Difference.
