It can ensure the color richness and display details of dynamic pictures. Existing transparent screens are equipped with brightness sensors and touch components, enabling the transparent screen to automatically adjust the brightness according to the surrounding environment and interact with consumers.

[0004] The intelligent transparent screen device of the prior art only uses a single Bluetooth or a single WIFI or a single MCU control box to directly output control signals, and the display screen is an ordinary non-transparent screen.

[0037] In the above embodiment, various types of wireless control units can be adopted.

[0049] In this embodiment, the first power conversion unit converts the voltage input by the power input unit into a low voltage, and the voltage remains stable, so that the two wireless control units can operate stably and the service life can be extended.

[0050] Optionally, the control module further includes: a fuse unit electrically connected to the power input unit, which is used to provide overcurrent protection for the control module and the transparent display module. When overcurrent or overvoltage occurs during the operation of the entire device, the fuse unit can automatically blow, thus cutting off the circuit and ultimately protecting the electronic components from being burned out.

[0051] Preferably, the control module further includes: a soft start unit electrically connected to the power input unit, which is used to filter the surge overshoot voltage. Similarly, it can provide protection for the electrical components inside the device to avoid being burned out or broken down.

Here, it should be noted that: through the signal enhancement effect of the second signal enhancement unit, the attenuation phenomenon generated during signal transmission is greatly reduced, ensuring that the signal strength does not deteriorate due to the loss of the transmission medium itself during the transmission process.

[0054] Further preferably, the transparent display module further includes a third signal enhancement unit, and the third signal enhancement unit is serially arranged between the driving and scanning display unit and the output connector, which is used to enhance the received control signal and then output it. Similarly, through the signal enhancement effect of the third signal enhancement unit, the attenuation phenomenon during signal transmission can be reduced, ensuring that the signal strength remains unchanged.

[0055] Preferably, the number of the transparent display modules is multiple, and multiple transparent display modules are cascaded. For example, in one embodiment, 10 transparent display modules can be cascaded with each other to form a transparent display screen array with a larger area and control range, which can undoubtedly display more information and is suitable for displaying dynamic pictures or information to passers-by in large venues such as squares.

[0056] Generally speaking, in the intelligent transparent screen device provided by the present utility model, two wireless control units are adopted.
