For example, when the projection display screen 011 and the display array 022 are attached directly together, each pixel light source 021 is correspondingly accommodated in each projection display cell 012. For another example, projection display screen 011 is within 5 mm of display array 022. Therefore, by carrying out microspur projection on the display screen, the optical power loss caused by light transmission can be greatly reduced.
Preferably, as shown in fig. 2, the projection display grid 012 is an invaginated cavity isolated from each other. From this, corresponding pixel light source just in time projects in this projection display check and can not project light other projection display check, can guarantee like this that the spotlight nature of each pixel light source after projecting the projection display check can be better, has eliminated the dazzling effect that the light source sent light direct display to bring.
Preferably, the pixel light source includes a light source such as an LED light source, an OLED light source, an LCD light source, or the like, which can be independently controlled by the pixel.
Preferably, the projection display cell 012 includes a transmission layer, the transmission layer is provided with a transmission surface, and the pixel light source emits light in the form of a point light source and projects the light from the projection display screen in the form of a surface light source after projecting the light onto the transmission surface. Preferably, the light emitted by the pixel light source is projected to the transmission surface and then transmitted out in parallel in a direction perpendicular to the projection display screen. Fig. 3 is a cross-sectional view of the projection display cell 012, in which a schematic diagram of the light path along which light travels is shown. The pixel light sources 021 are correspondingly accommodated in the recessed cavities of the projection display cells 012, and in the main direction along which the pixel light sources 021 emit light rays to propagate, the transmission layer 121 is disposed in front of the projection display cells 012, preferably, the pixel light sources 021 are hemispherical point light sources, the transmission layer 121 includes a transmission surface 122 having a hemispherical structure, and the light rays 211 emitted by the pixel light sources 021 are projected onto the transmission surface 122 and then are transmitted out in parallel in a direction perpendicular to the projection display screen.

Preferably, the transmissive layer 121 is colorless transparent glass or plastic, or colored transparent glass or plastic that absorbs harmful light such as ultraviolet rays.
Preferably, the light blocking layer 123 is disposed behind the projection display grid 012, so that the light blocking layer 123 is seen to be absorbed by the light blocking layer 123 and cannot be transmitted, thereby preventing light emitted by adjacent pixel light sources from crosstalk after passing through the projection display grid 012, which may cause light interference.
On the basis of fig. 3, as shown in fig. 4, the projection display screen further includes a polarizing layer 131 disposed outside the transmissive layer 121, and the polarizing layer 131 changes the polarization direction of the light transmitted from the transmissive layer 121.
It is further preferred that the polarization directions of the polarization layers corresponding to the pixel light sources of each row of the display array on the projection display screen are the same, and the polarization directions of the polarization layers corresponding to adjacent rows of the display array are opposite. Alternatively, preferably, the polarization directions of the polarization layers corresponding to the pixel light sources of each column of the display array are the same, and the polarization directions of the polarization layers corresponding to adjacent columns of the display array are opposite. For example, as shown in fig. 5, the polarizing layer 131 outside the transmissive layer 121 of the projection display screen has two polarization directions, and the polarizing layers of the two polarization directions, i.e., the first polarization direction polarizing layer 1311 and the second polarization direction polarizing layer 1312, are alternately distributed on the projection display screen in row units. Or, preferably, the polarization directions of the polarization layers corresponding to the adjacent pixel light sources in each row of the display array are opposite, and the polarization directions of the polarization layers corresponding to the adjacent pixel light sources in each column of the display array are also opposite, which is called a "checkerboard" layout manner, for example, the polarization direction corresponding to the pixel light source in the first row is "left, right, left and right … …", the polarization direction corresponding to the pixel light source in the second row is "left, right and left … …", the polarization direction corresponding to the pixel light source in the third row is "left, right, left and right … …", and so on.

By the method, the projection display screen can present a three-dimensional video effect, and a three-dimensional stereo image can be displayed by matching with the conversion of the light source display content of the display array.
Preferably, the polarizing layer 131 may be a polarizing film adhered to the outer side of the transmissive layer 121, or a polarizing layer engraved on glass or plastic by a laser etching method.

Preferably, the transmissive layer is smooth enough to not be frosted in this case, which would otherwise affect the polarization-induced three-dimensional display.
On the basis of fig. 4, as shown in fig. 5, the projection display screen further includes a filter layer 141 disposed outside the polarizing layer 131, and when light transmitted from the polarizing layer 131 passes through the filter layer 141, the filter layer 141 attenuates harmful light components therein.

Further preferably, the outer surface of the projection display screen is a frosted surface, and the frosted granularity of the frosted surface is matched with the size of the pixel light source. The fitting means that the larger the size of the pixel light source is, the larger the frosted surface graininess or roughness is, otherwise, the smaller the size of the pixel light source is, the finer the frosted surface graininess or roughness is. The dazzling effect of light can be effectively weakened through the frosting surface, so that the emitted light is more fused.
Preferably, the display control terminal manually adjusts the luminance of the pixel light sources of the display array, or adaptively adjusts the luminance of the pixel light sources after sensing the outside light luminance. The method can adjust the brightness of the light source, so that the brightness of the display system can meet the optimal visual effect of the human eyes, and meanwhile, the display system has the advantages of reducing energy consumption, improving environmental adaptability and the like.
