Answer: A, 65536 4096
Answer analysis:
When discussing this question, we first need to understand the concept of grayscale of LED display.
Grayscale refers to the brightness level that can be distinguished from the darkest to the brightest in the brightness of the single primary color of the LED display.
The higher the grayscale level, the more natural the color transition, the more delicate the image display, the richer the color, and the higher the cost of the corresponding display control system.
Now, let's analyze the options in the question:
A, 65536 4096: This option means that the grayscale level of the indoor 1/8 scan LED display is 65536, while the grayscale level of the outdoor static LED display is 4096.
Indoor display screens usually require a higher grayscale level to ensure the delicacy and color richness of the image due to the close viewing distance, so the grayscale level of 65536 is reasonable.
However, outdoor display screens also require a certain grayscale level due to the long viewing distance and the great influence of ambient light, but usually do not need to be as high as indoor display screens. However, the grayscale level of the outdoor display in this option is relatively low, which is reasonable.
B, 16384 65536: The grayscale level of the indoor display in this option is low, while the grayscale level of the outdoor display is higher, which does not meet the needs of actual applications, because indoor displays usually require higher grayscale levels to ensure image quality.
C, 4096 16384: The grayscale level of this option is relatively low for both indoor and outdoor displays, which is not enough to meet the needs of high-quality image display.
D, 512 65536: The grayscale level of the indoor display is too low, while the grayscale level of the outdoor display is too high, which is also inconsistent with the needs of actual applications.
Comprehensively considered, indoor displays require higher grayscale levels to ensure the fineness and color richness of the image due to the short viewing distance.
Although outdoor displays also require a certain grayscale level, due to the long viewing distance and the influence of ambient light, their grayscale level usually does not need to be as high as that of indoor displays.
Therefore, the grayscale level of indoor 1/8 scan LED display is usually 65536, while the grayscale level of outdoor static LED display is also important, but it usually does not need to reach 65536. 4096 or higher grayscale levels can meet most outdoor display needs.
In summary, the correct answer is A: 65536 4096.
