The light emission control principle of the planar sub-light source plate 10 may be as follows: the singlechip main control circuit 202 communicates with the computer through the serial port to USB circuit 201, namely, the serial port to USB circuit 201 is used for transmitting the required brightness data issued by the computer; correspondingly, the singlechip main control circuit 202 receives the required brightness data through the serial port-to-USB circuit 201 and transmits the required brightness data to the analog-to-digital conversion circuit 203 according to high and low positions; the analog-to-digital conversion circuit 203 receives the digital signal transmitted by the singlechip main control circuit 202, converts the digital signal into an analog signal and transmits the analog signal to the amplifying circuit 204; the analog signal received by the amplifying circuit 204 and output by the analog-to-digital conversion circuit 203 is usually weak, and the amplifying circuit 204 can amplify the weak analog signal and drive the lamp bead 104 to emit light; the light emitted by the lamp beads 104 is homogenized by the diffusion plate 202 to form the emergent light of the planar sub-light source plate 10.
In one embodiment, the Light beads 104 are Light-Emitting Diode (LED) Light beads.
The LED lamp bead adopts the semiconductor chip as the luminous material, and compared with the traditional incandescent lamp, the LED lamp bead has the advantages of low energy consumption, quick response, environmental protection, less heat generation, capability of working in a high-speed light-on state and the like, so that the dynamic range corresponding to the real scene can be simulated more accurately.
In one embodiment, the maximum luminance value of the light emitted from the planar sub-light source plate 10 is equal to or greater than 20000cd/m2(candela/m squared).
Therefore, the simulation of the real scene with a large dynamic range is convenient to realize.
Illustratively, the maximum luminance of the light emitted from the planar sub-light source plate 10 is 20000cd/m2、30000cd/m2Or other brightness values, which can be set based on the requirements of the light source board apparatus 100, are not described or limited herein.
In one embodiment, the uniformity of the brightness of the light emitting surface of the planar sub-light source plate 10 is equal to or greater than 90%.
Therefore, the brightness control is convenient to realize, and the simulation accuracy of the dynamic range of the real scene is improved.
For example, the uniformity of the brightness of the light-emitting surface of the planar sub light source plate 10 is equal to 90%, 93%, 95% or other percentage values, which can be set based on the requirements of the light source plate device 100, and is not described nor limited herein.
In one embodiment, the light output brightness of the planar light source sub-panel 10 is continuously adjustable, or the number of adjustable steps of the light output brightness of the planar light source sub-panel 10 is equal to or greater than 1000 steps.
Therefore, the continuous adjustment or small gradient adjustment of the dynamic range is convenient to realize, and the simulation accuracy of the dynamic range of the real scene is higher.
For example, when the brightness of the light emitted from the planar light source sub-panel 10 is adjusted in a gradient manner, the adjustable number of stages is equal to 1000, 1500, and 2000 or other values, which can be set based on the requirements of the light source panel apparatus 100, and is not described or limited herein.

The area between the adjacent planar sub-light source boards 10 is a non-light-emitting area, and the gap between the adjacent planar sub-light source boards 10 is reduced, so that the non-light-emitting area in the light source board device 100 can be reduced, the brightness continuity of the whole light-emitting surface of the light source board device 100 is better, and the more accurate simulation of the dynamic range of the real scene is realized.
For example, the gap between adjacent planar sub-light source boards 10 is equal to 1 cm, 0.85 cm, 0.5 cm or other distance values, which can be set based on the requirements of the light source board apparatus 100, and is not described or limited herein.
In the above embodiment, the planar light source sub-plate 10 may be a commercial product, and the model thereof may be selected from commercial products, so as to save the design and customization processes of the planar light source sub-plate 10, and also save the cost; or the planar sub-light source plate 10 may be customized by the manufacturer to meet the individual requirements of the live-action dynamic range simulation, which is not limited herein. Meanwhile, the brightness of the selected planar light source sub-plates 10 can be independently adjusted, and the brightness of the planar light source sub-plates 10 corresponding to the selected model can be continuously adjusted or the number of adjustable stages is more than 1000. The planar sub light source plate 10 has a serial communication function so as to program and control the light brightness. Further, to simulate a high-brightness sky area, the highest brightness of the light-emitting surface of the selected planar sub-light source plate 10 should be as large as possible, for example, not smaller than 20000cd/m2.
