The number of the sub-pixels is set to be N, N is larger than or equal to 2, and the larger the value of N is, the clearer the reproduced image is. As shown in fig. 9 and 10, one pixel cell group is divided into 9 sub-pixels of the same size, P1 to P9.
In a specific implementation, in the reflective holographic display device provided in the embodiment of the present invention, the phase plate may have a plurality of phase plate units corresponding to the pixel unit groups one by one; each phase plate unit may be divided into a plurality of sub-regions; the phases of the sub-regions in the same phase plate unit are different, and specifically, the heights of the phase plates corresponding to the sub-regions in the same phase plate unit are different; or the phase plates corresponding to the sub-regions in the same phase plate unit have different refractive indexes, so that different phases are selected, different phases of the incident light can be realized, light waves with different phases are converged to human eyes, and different depths of field can be realized. As shown in fig. 9 and 10, the pixel cell group shown on the left corresponds to the phase plate cell shown on the right one-to-one, and the phase plate cell is divided into 9 equal-sized sub-regions, R1 to R9.
The phase plate according to the embodiment of the present invention is generally composed of a diffraction grating, and can be classified into a transmission type and a reflection type according to the operation mode. The reflection type grating is characterized in that a trace is carved on a metal mirror, total reflection occurs on a notch, diffraction occurs in the direction of reflected light at the position where the notch is not carved, and the reflection type grating is equivalent to a group of diffraction gratings; the transmission type grating is formed by engraving a nick with equal interval on the optical flat glass, and the nick is opaque and has no light-transmitting slit.
Theoretically, the diffraction angle theta of the m-order diffraction wave of the grating is only composed of the grating period P, the wavelength lambda of the incident wave and the incident angle theta0It is decided that,
sinθ-sinθ0＝mλ/P(m＝0,±1,±2,…) (1)
generally, the diffraction intensity of 0-order diffraction and first-order diffraction of the transmission grating is larger, and the diffraction order of high order is much smaller than that of the first-order diffraction and the second-order diffraction; the 0-order diffracted wave is along the incident light direction, and the diffraction direction of the first-order diffracted wave can be regulated and controlled by the period of the grating, so that the first-order diffracted wave is generally used for regulating the light angle (when the light-emitting direction is equal to or very close to the incident wave, the zero-order diffracted wave can also be used). When the light emitting direction is given, the grating periods corresponding to different color lights are determined by the formula (1). The duty ratio is typically 0.5, but may deviate from this value in practical product design (e.g. for reasons of adjusting the intensity of the emitted light, balancing the brightness difference at different positions of the display panel, process conditions, etc.). The height of the grating, typically around 300nm, may be slightly larger, e.g. 1um, or slightly smaller, e.g. 200 nm. The height of the grating can be designed according to the wavelength for the purpose of eliminating, weakening or enhancing the zero-order diffraction wave of certain color light, and because the incident angle is fixed, when the phase difference of the color wave on the grating bars and the gaps of the grating is odd times of the half wavelength, the zero-order diffraction wave is subjected to coherent cancellation, the zero-order wave is subjected to coherent weakening, and the first-order wave is enhanced; when the phase difference is integral multiple of the wavelength, the zero-order wave coherence is enhanced, and the first-order wave is weakened. Different colors can be selected from different grating heights, and can also be selected from the same.
The phase plate can be a transmission grating, a reflection grating, a blazed grating or a echelle grating, and can be theoretically explained by the formula. The blazed grating is also a reflection type grating, and is characterized in that the groove surface of the blazed grating is not parallel to the grating surface, and an included angle gamma is formed between the groove surface and the grating surface, so that the central maximum of single groove surface (equivalent to a single slit) diffraction is separated from the interference zero-order main maximum between the groove surfaces, and light energy is transferred from the interference zero-order main maximum and is concentrated on a certain level of spectrum, thereby realizing the blazed of the level of spectrum.
Further, in a specific implementation, in the above-described reflective holographic display device provided in an embodiment of the present invention, specifically, in one pixel unit group and the phase plate unit corresponding to the pixel unit group, as shown in fig. 9, each sub-pixel corresponds to each sub-region one-to-one, that is, P1 corresponds to R1, P2 corresponds to R2, P3 corresponds to R3, P4 corresponds to R4, P5 corresponds to R5, P6 corresponds to R6, P7 corresponds to R7, P8 corresponds to R8, and P9 corresponds to R9, where the reference light is preferably collimated light; alternatively, as shown in fig. 10, one sub-pixel corresponds to a plurality of sub-regions, i.e., P5 corresponds to R1, R2, R3, R4, R5, R6, R7, R8, and R9, respectively, and in this case, the reference light is preferably incident light having a certain divergence angle.
In particular, the embodiment of the present invention provides an above-mentioned reflective holographic display device, wherein the front light source module can be set as a side-in type or a direct type. When the front light source module is in a side-in type light incoming mode, the front light source module specifically comprises a light guide plate and a light emitting diode positioned on the light incoming side of the light guide plate; or, when the front light source module is a direct-type light inlet, the front light source module may specifically include a back plate and a light emitting diode located on the back plate and close to the light outlet side of the display panel. Preferably, the front light source module is arranged to direct light.
It should be noted that the reference light may be a surface light source or a point light source, collimated light or non-collimated light, and preferably, the reference light is set as collimated coherent light. The reference light may be obtained by replacing the holographic plate with a Charge-coupled Device (CCD) or a Complementary Metal-Oxide-Semiconductor (CMOS) image sensor when recording the holographic image, and converting the three-dimensional topography of the surface of the object obtained by the CCD or the CMOS into digital holographic information as information of the reference light.
