Description of the drawings
By reference to the following description in conjunction with the accompanying drawings and the contents of the claims, and with to the present invention more comprehensively
Understand, other objects and results of the present invention will be more clearly understood and understood.In the accompanying drawings：
Fig. 1 is the touch display screen schematic cross-section that embodiment provides；
Wherein：11- luminescent panels, 111- light emitting diodes, 12- touch panels, 13- light blocking plates, 131- light transmission apertures,
14- image sensor chips, 15- light transmission protection boards, 16- light transmission pieces.
Identical label indicates similar or corresponding feature or function in all the appended drawings.
Specific implementation mode
Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is the touch display screen schematic cross-section that embodiment provides.As shown in Figure 1, provided in an embodiment of the present invention touch
It includes luminescent panel 11, touch panel 12, light blocking plate 13 and image sensor chip 14 to touch display screen.Wherein, touch panel 12 is set
It sets in the upper surface of luminescent panel 11, light blocking plate 13 is arranged in the lower surface of luminescent panel 11, and the setting of image sensor chip 14 exists
The lower surface of light blocking plate 13.
It is provided with the light emitting diode 111 of array arrangement on luminescent panel 11 and drives each 111 work of light emitting diode
The circuit of work.Each light emitting diode 111 is respectively at different working conditions, combination formation figure under control of the control signal
Picture.The light that each light emitting diode 111 is sent out projects touch display screen by touch panel 12.
Touch panel 12 is used for pressure when sensing user touch display screen, and the position of user's effect on the touchscreen is sat
Mark is converted to the corresponding instruction of corresponding region.
As shown in Figure 1, being provided with light transmission aperture 131 on light blocking plate 13, the light that luminescent panel 11 is sent out is irradiated to tactile
Touch screen upside, user the positions such as finger when, light is reflected onto touch display screen, and reflected light line passes through touch panel
12, the light transmission aperture 131 on luminescent panel 11 and light blocking plate 13 is irradiated to image sensor chip 14.
In the present embodiment, luminescent panel 11 is arranged with corresponding to the region light transmission of the field angle of light transmission aperture 131, image sensing
Chip 14 also corresponds to the setting of 131 field angle of light transmission aperture.Because the size original of light transmission aperture 131 is less than the size of other component,
So can form pinhole imaging system at light transmission aperture 131, the light being irradiated on image sensor chip 14 forms user's touching
The texture at touch display screen position.The image that corresponding processing component obtains image sensor chip 14 can be sentenced after handling
Whether disconnected be display screen that designated user touches, also can then determine whether to open the smart machine for installing touch display screen
Lock operation.

The region that image sensor chip 14 corresponds to each 131 field angle of light transmission aperture is not overlapped.Each light transmission aperture 131 is irradiated to image
On sensing chip 14.In this way, the very little that the thickness of luminescent panel 11, touch panel 12 can be arranged so that touch display screen
Thickness correspondingly reduces.
Certainly, in other embodiment, light transmission aperture 131 can also only be set as one；Correspondingly, luminescent panel 11 and touch
The thickness for touching panel 12 needs correspondingly to increase.
As shown in Figure 1, in the present embodiment, light transmission protection board 15 is additionally provided in the upper surface of touch panel 12.Light transmission is protected
Backplate 15 is for protecting touch panel 12 to be damaged because of external impacts.In order to realize the modularization of touch display screen, touch aobvious
Display screen can be with protection setting in 14 side of luminescent panel 11, touch panel 12 and image sensor chip plastic frame；In addition,
Coat of metal can also be arranged in the lower surface of image sensor chip 14.
As shown in Figure 1, in the present embodiment, light transmission piece 16 is additionally provided between light blocking plate 13 and image sensor chip 14.
Light transmission piece 16, which is arranged, can suitably increase the area of 131 corresponding image sensor chip of light transmission aperture, 14 photosurface so that figure
As more photosensitive units are used to form the image of light transmission aperture 131 in sensing chip 14, then ensure picture quality.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
