Certainly, in some embodiments, above-mentioned matrix 42 may not be necessary, and multiple anti-units 41 of increasing are directly set
It sets between display device 20 and imaging device 30.
It is explained below and increases the concrete principle that anti-unit 41 is used to enhance the energy that interference optical signal is reflected:
Referring to Fig. 7, interference light is believed in diffracted light signals as described above, diffraction occurs when passing through viewing area 21 for optical signal
It number reaches and to increase on anti-unit 41, reach the interference optical signal a part for increasing anti-unit 41 and reflected by increasing anti-unit 41, another part
Across the anti-unit 41 of increasing.Increasing anti-unit 41 enhances the energy that interference optical signal is reflected in diffracted light signals, and due to being incident to
The energy for increasing the interference optical signal of anti-unit 41 is certain, therefore, across the energy dropoff for the interference optical signal for increasing anti-unit 41, with
Reduce the energy for entering the interference optical signal of imaging device 30.
It in one example, include the optical signal of multiple levels incorporated by reference to Fig. 8 (a), in diffracted light signals, wherein 0 grade of light
Signal is the target optical signal for imaging, and the optical signal of remaining level (± 1, ± 2, ± 3) is interference optical signal.Increase anti-single
Member 41 can be used for weakening interference optical signal and pass through the energy after increasing anti-unit 41.
Specifically, incorporated by reference to Fig. 9 and Figure 10, interfering the gross energy of optical signal Li is I, and it is anti-that interference optical signal Li is incident on increasing
In unit 41, part forms transmitted light Lt after interfering optical signal Li to pass through the anti-unit 41 of increasing, and part interferes optical signal Li by increasing instead
The first reflected light L1 is formed after the plane of incidence reflection of unit 41, part interferes optical signal Li to be reflected by the exit facet for increasing anti-unit 41
After form the second reflected light L2.
By taking the waveform of incident interference optical signal Li is the waveform such as Figure 10 (a) as an example, wherein horizontal axis is phase, the longitudinal axis
For amplitude, then the waveform (shown in such as Figure 10 (b)) of the first reflected light L1 and the phase difference of the waveform of interference optical signal Li are 0.By
It compares the first reflected light L1 in the second reflected light L2 and passes through more and increase anti-unit 41 twice, waveform (such as Figure 10 of the second reflected light L2
(c) shown in) and the waveform of the first reflected light L1 between may have phase difference.It is anti-single when increasing if interfering the wavelength of optical signal is λ
When the thickness of member 41 is equal to λ/8, the optical path difference that the second reflected light L2 compares the first reflected light L1 is λ/8 × 2=λ/4, the light of λ/4
Path difference will make the constant phase difference of the second reflected light L2 and the first reflected light L1 be pi/2, the reflection of the second reflected light L2 and first
Light L1 is interfered, so that the gross energy R of reflected light is enhanced, shown in gross energy R such as Figure 10 (d) of reflected light.According to energy
Conservation theorem is measured, then the energy T=I-R of transmitted light Lt will weaken, therefore reduce across the interference optical signal for increasing deinstall 40
Energy, so that the optical signal into imaging device 30 is the optical signal as shown in Fig. 8 (b) after actually cutting through increasing deinstall 40,
In, 0 grade of optical signal is not increased anti-unit 41 and is weakened, and the optical signal of remaining level (± 1, ± 2, ± 3) is increased anti-unit 41 and cut
Weak, the signal-to-noise ratio of the optical signal for imaging is improved.
To sum up, it in the terminal 100 of the application embodiment, is received by imaging device 30 and the optical signal for being used for imaging is successive
Across viewing area 21 and increase deinstall 40, anti-unit 41 is increased by setting, to increase in the optical signal by 20 diffraction of display device
Interference optical signal, the energy for being increased anti-unit 41 and reflecting reduces interference optical signal and passes through the energy for increasing anti-unit 41, to reduce
The influence that imaging device 30 be imaged of interference optical signal, when raising imaging device 30 is arranged in below display device 20 at image quality
Amount.
Figure 11 is please referred to, in some embodiments, increasing anti-unit 41 includes multiple Anti-reflective coatings 411 being stacked.It is dry
The interference optical signal through Anti-reflective coating 411 can repeatedly be weakened successively by multiple 411 multiple reflections of Anti-reflective coating by disturbing optical signal
Energy further increases image quality.When manufacture increases anti-unit 41, Anti-reflective coating 411 can be successively manufactured, and increased instead by multilayer
Film 411, which is constituted, increases anti-unit 41.
Further, the thickness of the same multiple Anti-reflective coatings 411 for increasing anti-unit 41 is not identical.It can from above-mentioned principle analysis
To know, the Anti-reflective coating 411 of different-thickness (h) can be used for enhancing the reflected energy of the optical signal of corresponding wavelength (λ),
In, the corresponding relationship of thickness h and wavelength X is λ/8 h=, and interferes the optical signal that may include multi-wavelength in optical signal, is passed through
The Anti-reflective coating 411 of different-thickness is set, the interference optical signal of corresponding different wave length can be made to be weakened.Specifically, each
The thickness of Anti-reflective coating 411 can be [47.5,95] nanometer, for example, thickness can be 47.5 nanometers, 50 nanometers, 51 nanometers, 65 receive
Rice, 70 nanometers, 82 nanometers, the numerical value in any of the above-described ranges such as 95 nanometers.Accordingly, use thickness range for [47.5,95]
The Anti-reflective coating 411 of a thickness in nanometer, can increase to wave-length coverage is a corresponding wavelength in [380,760] nanometer
Interference optical signal reflected energy.The interference optical signal of wave-length coverage [380,760] nanometer is visible light signal, therefore,
Anti-reflective coating 411 in above-mentioned thickness range can reduce influence of the visible light signal to image quality in interference optical signal, mention
The image quality of high visible image.
Figure 12 is please referred to, it is in some embodiments, same to increase anti-list on the direction close along four circumferential central axis Z
The thickness of member 41 is gradually increased.In actual use, the diffraction principle of foundation light, the optical signal of the identical level of different wave length
Position can be variant, and specifically, under identical level, for longer wavelengths of optical signal closer to 0 grade, the shorter optical signal of wavelength is farther
From 0 grade.And the same interference optical signal for increasing anti-unit 41 and can be used for weakening the different wave length of identical level, therefore, for
It is same to increase anti-unit 41, on the direction close along four circumferential central axis Z, the thickness equipment for increasing anti-unit 41 is obtained and is gradually increased
Greatly, the characteristic distributions of the interference optical signal at the same level of different wave length are adapted to, realize more preferably anti-tampering effect.
