Description

Technical Field

[0001] The invention relates to the field of display screens, and in particular to a combined intelligent display screen assembly. Background Art

[0002] With the development of the Internet, traditional advertising models can no longer meet the needs of the audience and the requirements of merchants. Therefore, merchants began to explore new advertising models, and LED advertising came into being. It can not only meet the needs of the public, but also meet the needs of many merchants. Especially in recent years, the continuous innovation and development of LED display screens have improved the promotion conversion rate of LED advertising, making the development of LED advertising even better.

[0003] The patent with the authorization announcement number CN111210738B proposes a combined intelligent display screen assembly and a control method thereof, including a housing, the interior of which is divided into an installation cavity and a battery cavity; a lithium battery is installed in the battery cavity; a control module, a power module and a display assembly are installed in the installation cavity; the control module is equipped with a communication module; the display assembly includes a first rotating drum, a second rotating drum, a first motor, a second motor, an LCD display screen, an electronic paper display screen and a flexible substrate; the first rotating drum and the second rotating drum are respectively arranged on both sides of the installation cavity and are arranged parallel to each other; the output shafts of the first motor and the second motor are respectively coaxially connected to the first rotating drum and the second rotating drum; the LCD display screen is installed under the transparent plate through a mounting frame; the flexible substrate is located between the transparent plate and the LCD display screen, and the two ends are respectively fixed and wound on the first rotating drum and the second rotating drum; the electronic paper display screen is flat on the upper surface of the flexible substrate. The present invention achieves the effect of saving electric energy by combining display.

[0004] The above patent uses an electronic paper display, but the electronic paper display itself does not emit light. The stronger the light, the clearer the electronic paper display. When the external lighting conditions are poor or it is completely dark, the electronic paper display will appear unclear or completely non-displaying. In the above patent, the advertisements displayed on the electronic paper display will not be clearly visible when it is dark, affecting the overall use of the device.
